Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.

Why remodel with a CSLB-licensed SF contractor

San Francisco does not issue its own general contractor license. The California Contractors State License Board (CSLB) is the statewide licensing authority, and the Class B General Building Contractor license is the credential any prime contractor on an SF residential remodel of any meaningful scope must hold. What San Francisco adds on top of CSLB is a dense regulatory overlay: Department of Building Inspection permits, SF Planning Department zoning and environmental review, Historic Preservation Commission Certificate of Appropriateness on landmark districts, San Francisco Fire Department Bureau of Fire Prevention review on high-rise and R-occupancy work, BAAQMD dust and VOC compliance, the Mandatory Soft-Story Retrofit Program on pre-1978 multi-unit buildings, the SF Rent Ordinance on rent-stabilized buildings, Planning Code §311 neighborhood notification and §317 demolition control, CEQA environmental-review triage, and the SF Noise Ordinance on construction hours. The net effect is that an SF remodel stacks more layered regulatory review than a comparable Los Angeles or Austin project — even though the GC licensing itself is the same statewide CSLB layer.

This is by design. SF's housing stock, its seismic posture, its preservation of Victorian and Edwardian architecture, and its decades-long rent-stabilization regime have all produced regulatory structures that other US cities do not have. A homeowner who verifies only that 'the contractor is CSLB-licensed' has verified a necessary condition, not a sufficient one. The SF-specific competence — knowing the DBI plan-review conventions, knowing which Planning counter staffer to consult on a §311 triage question, knowing the HPC Article 10 vs Article 11 distinction, knowing which Soft-Story Retrofit tier a building belongs to, knowing how §37.9C tenant-displacement payments interact with a Rent-Ordinance-covered remodel — is what distinguishes a contractor who will deliver the project on schedule from one who will spend the first six months learning SF's overlays at the homeowner's expense.

AskBaily built a government-direct verifier for exactly this. Wave 181 shipped automated CSLB verification; the same verifier that runs on every /los-angeles project runs identically on every SF project. The difference is the partner GC's own license number, not the verification mechanism. When a vetted SF-area Class B GC signs through the /for-pros pathway, their CSLB record flows into the cached- verification system that renders the card below. Until an SF partner is live, the card below is an honest receipt-shape demonstration using NPLD's actual CSLB #1105249 — clearly labeled because NPLD's real service area is LA / Malibu / Ventura, not San Francisco.

Honest status: AskBaily is pre-launch for SF partner GCs as of the Wave 257 ship. The card below renders a live CA-jurisdiction skeleton using the clearly-labeled sample credential CSLB #1105249 — sample / SF partner pre-launch (NPLD scope is LA) to demonstrate the receipt shape. We do not fabricate an SF partner's license number because CSLB records are publicly searchable by business name and license number — inventing a number would be both dishonest and trivially falsifiable. When a vetted SF Class B GC completes the Wave 187 manual-review path, their live CSLB Class B record replaces this skeleton with no further code changes on this page.

This matters for San Francisco specifically because SF's housing stock is the oldest of any major US west- coast metro and its regulatory overlays are the most layered in California. A significant share of SF's residential buildings are Victorian (1860s-1900) or Edwardian (1900-1920) — buildings that pre-date modern structural, electrical, plumbing, fire, and seismic codes entirely. Retrofitting these buildings for modern kitchens, baths, and accessibility requires a contractor who can hold three conversations at once: the structural conversation (foundation bolting, shear-wall upgrade, soft-story retrofit where applicable), the envelope conversation (lead paint, asbestos in plaster and flooring, knob-and-tube wiring, galvanized supply and cast-iron drain lines), and the preservation conversation (original window restoration vs replacement, facade carpentry integrity, interior trim and plaster detail). Most SF remodels touch at least two of the three. A contractor who knows only one — or worse, who promises to do the work at LA labor rates without the SF overlays priced in — will deliver a project that breaks mid-build. The cost band difference between an SF-savvy Class B and a contractor winging it is typically 20-35% at the budget line and 3-9 months at the schedule line.

Practically, here is what an active CSLB license plus SF-specific competence give you on an SF remodel: permits filed by the GC in their own name with proper SF DBI coordination, not yours; access to the DBI Pre-Application path that catches review-track issues before a full construction set is produced; Planning review triage that catches §311, §317, and HPC issues upstream; CSLB surety-bond protection up to $25,000 under California Business & Professions Code §7071; workers-compensation coverage required on any contractor with employees; general-liability insurance in force on the jobsite; the ability to enforce a mechanics lien on real property under California Civil Code §8400 et seq. within the strict statutory windows; and the ability to close out a DBI permit with a finaled Certificate of Final Completion. An unlicensed or Class-C-only contractor acting as prime on a multi-trade residential scope forfeits nearly all of these protections.

The practical difference between a CSLB Class B holder with SF familiarity and an unlicensed handyman or a C-class specialty holder acting as prime on an SF kitchen, bath, whole-home gut, soft-story retrofit, Victorian restoration, or addition job is enormous. The Class B carries required general liability, follows EPA RRP on pre-1978 buildings, handles asbestos abatement through properly licensed subcontractors on pre-1981 materials, is legally entitled to pull DBI permits as prime, can retain a California-licensed architect for stamp-and-structural scope, can file a mechanics lien within California Civil Code's statutory windows, and leaves a clean paper trail at resale. The unlicensed or out-of-scope contractor cannot pull permits as prime (unless the homeowner files as owner-builder, which carries its own significant liability exposure), cannot enforce a lien, cannot close a Certificate of Final Completion, and leaves the homeowner personally liable for every code violation the project creates. California homeowner insurance frequently voids the moment the adjuster reads the word 'unpermitted' in the event of any loss traceable to unpermitted work.

Shared-lead marketplaces — Angi, Thumbtack, HomeAdvisor, Houzz Pro — cannot run live CSLB verification at SF resolution on their contractor rosters. They display user-submitted credentials with no CSLB-direct refresh. Expired and suspended CSLB numbers sit on their rosters for months; contractors holding only C-class specialty classifications list themselves with impunity as 'general contractors.' The FTC consent decree against HomeAdvisor (Matter 192 3113, settled March 2023 for $7.2 million) specifically faulted the company for misrepresenting license and background-check verification. AskBaily is building the structural answer: government-direct CSLB verification, SF-overlay- aware scoping, embedded on every matched SF page. The card below is the structural difference between lead-gen and a real platform.

Sample CSLB Class B receipt — pre-launch SF. Replaced with a live SF-area partner GC’s CSLB record when a vetted Class B holder signs through /for-pros. NPLD’s #1105249 is used here as a real-license receipt-shape demonstration; NPLD’s actual scope is LA / Malibu / Ventura.

Regulatory · 12 SF entities

San Francisco regulatory at a glance

Every San Francisco remodel touches between three and a dozen of the regulatory bodies, statutes, and ordinances listed below. Baily is trained on each one; generic LLMs are not. Plain-English summaries follow, each linked to the canonical glossary page and the authoritative government source.

The California Contractors State License Board is the statewide licensing authority for every general contractor working on an SF remodel of any meaningful scope. CSLB issues the Class B General Building Contractor license, requires a $25,000 surety bond, requires general-liability insurance (typically $1M per occurrence, $2M aggregate for SF work), and enforces mandatory workers' compensation on any contractor with employees. Every SF Tier-0 remodel on this site is scoped to a CSLB-licensed Class B holder; the verification is direct-from-cslb.ca.gov on every project, not a stale roster snapshot. CSLB #1105249 (sample below) renders the receipt shape; SF partner GCs go live when a vetted local Class B signs through /for-pros.

The San Francisco Department of Building Inspection is the permit, plan-review, and inspection authority for every construction activity inside SF city limits. DBI runs distinct tracks: Over-the-Counter (OTC) for minor interior non-structural work (same-day to 2-week turnaround), Standard Plan Review for typical kitchen/bath and light remodels (6-14 weeks), Complex Plan Review for additions, structural work, and multi-trade (12-24 weeks), and special review paths for high-rise, multi-family, and projects inside the Soft-Story Retrofit mandate. All filings run through DBI's Permit & Project Tracking system. DBI's plan-check rigor is substantially higher than most US cities; expect two or three review cycles on any complex scope before permit issue.

The San Francisco Planning Department is the zoning, urban-design, and environmental-review authority for every parcel in SF. Planning controls the RH-1, RH-2, RH-3, RM, RC, and NCD zoning classes; setback, rear-yard, height, and bulk limits; design review; CEQA lead-agency responsibility on most projects; discretionary-review hearings; and demolition-control oversight under Planning Code §317. Every SF permit that alters a building's footprint, height, or exterior expression goes through Planning in parallel with DBI. A Planning review can add 4-16 weeks (or substantially more if a Discretionary Review hearing is filed); a skilled Planning-savvy architect is usually more valuable than a stack of contractor bids.

The San Francisco Historic Preservation Commission reviews alterations in SF's 11 Article 10 Landmark Districts (Alamo Square, Bush Street-Cottage Row, Dogpatch, Duboce Park, Jackson Square, Liberty-Hill, Northeast Waterfront, Pacific Heights, South End, Telegraph Hill, Webster Street), ~220+ individual Article 10 landmarks, ~180+ Article 11 Category I-IV rated buildings, and properties within California Register historic districts. A Certificate of Appropriateness (CofA) or Permit to Alter from HPC must precede the DBI permit on any visible exterior change inside these overlays. Typical HPC review runs 8-20 weeks; complex whole-facade Victorian or Edwardian restorations extend to 26+ weeks. Interior alteration is unreviewed unless the interior itself is a designated interior landmark — extraordinarily rare.

The SF Mandatory Soft-Story Retrofit Program is the city's seismic-safety program targeting wood-frame buildings of three or more stories with five or more residential units, permitted before January 1, 1978, with a weak or open first story (typically ground-floor parking or storefront). Roughly 4,800 SF buildings were identified and issued compliance tiers beginning 2014. Required retrofit work includes steel-moment frames, plywood shear walls, and tie-downs at the ground-floor level. A non-compliant soft-story building faces Notices of Violation, loss of certificate of habitability, and — in most cases — inability to refinance through conforming mortgage products. Even partial remodels in these buildings interact with the retrofit requirement.

The San Francisco Rent Ordinance (administered by the SF Rent Board) covers buildings of two or more residential units permitted for construction before June 13, 1979. For any remodel in a rent-stabilized building, tenant habitability, relocation payments for temporary displacement (SF Administrative Code §37.9C), restrictions on reducing unit size or amenities, and the prohibition on eviction for capital improvements all become binding scope constraints. The Rent Ordinance interacts with DBI's permit process: permits that would reduce habitable square footage, eliminate a bedroom, or merge two units into one face heightened scrutiny. Owner-occupied single-family homes and post-1979 buildings are generally exempt.

SF Planning Code §311 requires neighborhood notification — typically a 30-day Section 311 Notice mailed to property owners and tenants within 150 feet — on most residential alteration, addition, and expansion permits. Any noticed neighbor may file a Discretionary Review (DR) request during the protest window, which suspends permit issuance and triggers a Planning Commission hearing. A DR adds 3-9 months and $10K-$50K in architect, expediter, and hearing-prep fees; roughly 5-10% of noticed permits draw a DR filing. §317 is the companion demolition-control provision: SF treats 'demolition' on a tonnage-removed and volumetric basis, not a colloquial one, and an unintended demolition finding can convert a 4-month remodel into a 14-month new-construction entitlement.

The San Francisco Fire Department Bureau of Fire Prevention reviews and inspects high-rise buildings (75+ feet above grade), R-1 occupancies (hotels, SROs), R-2 apartment buildings, mixed-use buildings with residential above commercial, and any project with fire alarm, sprinkler, or standpipe scope. SFFD runs parallel review to DBI on applicable projects and issues its own sign-offs at rough and final. For the typical single-family SF remodel, SFFD engagement is limited to smoke-alarm and carbon-monoxide-alarm compliance at final inspection; for ADU conversions in multi-unit buildings, for soft-story retrofits, and for any high-rise residential alteration, SFFD review is a separate critical-path clock that the GC must sequence.

The Bay Area Air Quality Management District regulates air-quality compliance across the nine-county Bay Area, including every SF construction site. On a residential remodel this means three things: (1) construction-dust control under Regulation 11-2 — soil watering, covered trucks, stabilized site entrance, typically documented via a site-specific Dust Control Plan on any project disturbing ≥1 acre or any demolition; (2) VOC compliance under Regulation 8-3 on architectural coatings — low-VOC paints, adhesives, and sealants are required across the board; (3) asbestos demolition / renovation notification under Regulation 11-2 — a 10-business-day advance notice and certified asbestos consultant for any demolition in buildings likely to contain asbestos (anything pre-1981). BAAQMD fines for missed asbestos notification start at $10,000 per day.

The California Environmental Quality Act is the state's environmental-review statute requiring agency analysis of potentially significant environmental impacts before discretionary approvals. Most SF single-family residential permits qualify for a Class 1 (existing facility) or Class 3 (new small structure) categorical exemption under CEQA Guidelines §15301 / §15303 and require no further environmental analysis. Projects in historic districts (§15331 historical-resource exemption with potential loss-of-exemption findings), in the coastal zone, with discretionary Planning Commission entitlements, or with potential significant impacts to historic resources can trigger full CEQA review — a tiered process running from Initial Study through Negative Declaration or full Environmental Impact Report. A full EIR on a contested SF project can add 12-24 months.

California SB 9 (the HOME Act, 2021) allows by-right lot splits and duplex construction on qualifying single-family parcels statewide. SF's qualifying SB 9 parcels are limited because most SF residential land is zoned RH-2 or RH-3 (already multi-family) rather than RH-1 (single-family), and the statute applies only to true single-family zones. Where SB 9 does apply — principally in the outer Sunset, outer Richmond, and a handful of RH-1 islands — it allows a homeowner to split a lot into two and build one unit on each, or to add a duplex on an existing single-family parcel, without a Planning Commission hearing. The state-law override preempts many SF-local restrictions but does not override CEQA-exempt historic resources or coastal-zone requirements.

SF Police Code Article 29 regulates construction noise, ambient noise, and noise variances across the city. On a residential site this means construction noise above 80 dBA at the property line is limited to 7am-8pm Monday through Saturday, and construction is prohibited on Sundays and holidays except with a filed variance. Extended-hours variances are available from DBI's Noise Complaint and Construction Management staff for $500-$2,500 and typically require 2-4 weeks to process; mitigation measures (noise blankets, time-of-day restrictions on the loudest equipment, notice to affected neighbors) are the norm. Interior finish work that stays below the property-line decibel threshold can sometimes run longer hours without a variance.

Process · 8 steps · consultation → Certificate of Final Completion

The 8-step San Francisco remodel process

Every AskBaily-scoped SF remodel moves through the same eight stages. OTC interior work compresses to 8-14 weeks of site time. Standard plan-review kitchen or bath remodels run 20-32. Full residential additions or Victorian restorations with HPC review run 36-72. The sequence never changes; only the duration does.

  1. Step 01

    Consultation and initial scope

    Book a conversation with Baily online or by phone. Share photos, your address, any prior DBI permit history, rent-stabilized status, historic-district status, and budget range. Baily returns a rough scope, a cost band, the applicable DBI permit track, whether SF Planning review will be required, whether HPC review will be required, and whether the building falls inside the Soft-Story Retrofit mandate or the Rent Ordinance — all in the same session.

    SF remodels bifurcate on six questions: is the parcel inside an Article 10 Landmark District or on an Article 11 rated building, does the building have two or more residential units permitted before June 13, 1979 (Rent Ordinance), is the scope large enough to trigger §311 neighborhood notification, is the building inside the Soft-Story Retrofit Program roster, is the scope potentially a §317 demolition, and is there any coastal-zone exposure (rare in SF proper but possible in some westside parcels). Baily answers all six from the address and photo set alone, so the scope conversation reflects the real permit path — not a best-case fantasy.

  2. Step 02

    Scope, feasibility, and existing-conditions walk

    The matched SF GC walks the home, confirms electrical panel capacity (many SF Victorians still run 60-100 amp service), plumbing-stack condition, gas-line material (cast-iron vs galvanized vs copper), load-bearing walls, foundation type (perimeter concrete vs brick vs pier-and-post), asbestos and lead-paint presence (anything pre-1981 is assumed asbestos-containing until tested), and any existing DBI permits open or recently finaled. Fixed-fee proposal follows within 5-7 business days.

    SF's housing stock skews old: a large fraction of Victorian (1860s-1900), Edwardian (1900-1920), early-modern (1920s-1940s), and mid-century (1940s-1960s) buildings carry existing-conditions complications that first-time renovators routinely underestimate. Galvanized water supply lines leak at the threads the moment they are disturbed. Knob-and-tube wiring on the upper floors of pre-1940 buildings must be decommissioned during any electrical scope. Pre-1981 materials require asbestos testing before any demolition. Foundation bolting to meet current seismic standards is a common scope line in Victorian and Edwardian homes. A contractor who skips the walk and bids from photos is setting up change orders; Baily's matched GC walks every home before issuing the fixed-fee proposal.

  3. Step 03

    CSLB license + bond verification

    Before a contract is signed, the matched SF GC's CSLB record is verified directly against cslb.ca.gov — active status, Class B General Building classification (required for any structural or multi-trade residential work), active $25,000 surety bond, general-liability insurance, and workers' compensation coverage if the contractor has employees. Verification is per-project, not per-signup; CSLB records refresh in real time. The LicenseCard on this page demonstrates the receipt shape live.

    AskBaily's Wave 181 verifier automates direct CSLB lookups and is the same tool used on /los-angeles. SF partner GCs go through the identical verification path; the only difference is the partner's own license number replaces the current sample. CSLB enforcement history is also checked — suspension, probation, revocation, and unresolved complaints are all surfaced. A contractor who claims a CSLB number that doesn't appear active, that doesn't include Class B classification, or that has an open formal accusation is filtered out before reaching the homeowner. SF-area contractors who hold only Class C specialty classifications (e.g., C-36 Plumbing, C-10 Electrical, C-54 Tile) cannot legally be the prime contractor on a multi-trade residential remodel; a C-class-only contractor acting as GC is a common red flag on Angi and Thumbtack rosters.

  4. Step 04

    DBI Pre-Application and Planning + HPC triage

    The architect or contractor files a DBI Pre-Application (or proceeds directly to a Planning Department counter review for small scopes) to confirm which DBI track applies, whether Planning review is required, whether §311 neighborhood notification will be triggered, and whether HPC Certificate of Appropriateness is required. Triage typically runs 2-6 weeks and saves 6-20 weeks downstream by catching path selection before a full plan set is produced.

    An SF Pre-Application is not a permit — it is a path-selection conversation with DBI and Planning staff that answers the gating question 'what review track will this project go through?' before the architect spends $30K-$150K on a full construction set. Triage outcomes include confirmation of DBI track (OTC, Standard, Complex), confirmation of Planning review (needed / not needed), confirmation of §311 notification (required / exempt), confirmation of §317 demolition classification (alteration / demolition), confirmation of HPC jurisdiction (CofA required / not required), and confirmation of whether any state-law overrides (SB 9, SB 35, ADU law §65852.2) apply. Skipping triage and filing a full permit set blind is how SF projects lose 6-12 months.

  5. Step 05

    SF Planning review (zoning, urban design, environmental)

    Planning reviews the proposed scope against the applicable zoning class (RH-1, RH-2, RH-3, RM-1 through RM-4, RC, NCD), setback and rear-yard requirements, height and bulk limits, and urban-design guidelines. CEQA lead-agency review runs in parallel. Most single-family residential remodels qualify for a Class 1 (existing facility) or Class 3 (new small structure) categorical exemption. §311 neighborhood notification is mailed if required; any filed Discretionary Review request triggers a Planning Commission hearing.

    Planning's timeline is the usual SF bottleneck. A Class 1 / Class 3 CEQA-exempt single-family residential alteration with no §311 notification clears in 4-8 weeks. A §311-noticed scope with no DR filing clears in 8-14 weeks (the 30-day protest window is the bottleneck). A DR-filed scope takes 24-44 additional weeks to reach a Planning Commission hearing, and the homeowner typically spends $15K-$50K on architect/expediter/hearing-prep fees. Historic-district parcels route to HPC in parallel; coastal-zone parcels (rare in SF proper, more common in adjacent Marin and San Mateo) route to the California Coastal Commission. State-law overrides (SB 9 ministerial lot splits, SB 35 streamlined ministerial, ADU statute §65852.2) bypass Planning Commission hearings on qualifying projects but require separate substantiation.

  6. Step 06

    SF Historic Preservation Commission review (when applicable)

    If the building is individually landmarked (Article 10 or Article 11) or sits inside one of SF's 11 Article 10 Landmark Districts — Alamo Square, Bush Street-Cottage Row, Dogpatch, Duboce Park, Jackson Square, Liberty-Hill, Northeast Waterfront, Pacific Heights, South End, Telegraph Hill, Webster Street — any visible exterior alteration requires a Certificate of Appropriateness from HPC before the DBI permit can issue. Review runs 8-20 weeks in parallel with Planning; complex whole-facade Victorian or Edwardian restorations extend to 26+ weeks.

    HPC review is not optional and not negotiable. Historic-district status is a parcel overlay that many SF buyers discover only at closing or — worse — at the first DBI counter visit. Baily checks landmark and rated-building status against the SF Planning GIS overlays at consultation. The architect prepares the HPC CofA submission package (materials cutsheets, elevations, historic photographs where available, window-and-door schedules, roofing samples) in parallel with the DBI filing so the two clocks overlap rather than sequence. HPC staff review and Commission hearing stages are distinct; a properly prepared staff-level CofA can often clear without a full Commission hearing. SF Heritage's informal advocacy and SF Architectural Heritage's advisory review are separate from formal HPC review and do not substitute.

  7. Step 07

    DBI plan review and permit issuance

    The plan set is filed through DBI's Permit & Project Tracking portal under the applicable track: OTC for minor interior non-structural (same day to 2 weeks), Standard for typical kitchen/bath with plumbing/electrical (6-14 weeks), Complex for additions and structural (12-24 weeks), or special tracks for high-rise, multi-family, and Soft-Story Retrofit work. Plan check typically runs two to three review cycles with corrections returned to the architect. Trade permits (plumbing, electrical, mechanical) may file separately or bundled. Issued permits carry itemized fee schedules including Planning review fees, SFFD fees where applicable, and impact fees on substantial additions.

    SF DBI plan review is more rigorous than comparable review in most US cities. Energy compliance under Title 24 2022 / 2025 is audited line by line; structural calculations for any load path change require stamped engineer review; fire-rated assembly details in multi-unit work are verified against the 2022 SF Building Code (based on 2021 IBC with SF amendments). Two review cycles is typical; three or four cycles on a complex Complex Plan Review project is not unusual. The architect and expediter answer plan-check corrections directly; the homeowner should not be in the response loop. Once the permit issues, trade-permit coordination (plumbing, electrical, mechanical, soft-story retrofit if applicable) is the next sequencing task.

  8. Step 08

    Construction, mechanicals, finishes

    With permit in hand and the CSLB-licensed GC holding the job, demo starts within SF Noise Ordinance hours (7am-8pm Mon-Sat, no Sunday work without variance). Asbestos abatement and lead-safe RRP work on pre-1978 surfaces sequences early. Framing, MEP rough-in, insulation, drywall, finishes, and final trade inspections proceed through DBI's inspection cadence — typically 8-20 inspections on a standard remodel, more on a complex addition or soft-story retrofit. BAAQMD dust control and VOC compliance remain in force throughout.

    SF construction is logistically harder than LA or Austin because of parking (every job needs an SFMTA temporary no-parking permit or daily street-parking dance), street width (fire access + disposal-truck access can force staging to back yards or roof drops), SFMTA street use permits for scaffolding or sidewalk-shed overhead, and the SF Rent Board's scrutiny of tenant habitability on multi-unit work. A skilled SF GC budgets these logistics costs explicitly rather than hiding them in the 'conditions' line. Winter-season (December-February) rain is the dominant schedule risk on any project that opens the roof or envelope; summer's persistent fog moderates the heat exposure that burdens Austin and Phoenix sites but does not eliminate weather delays.

  9. Step 09

    DBI final inspections and Certificate of Final Completion

    Structural, mechanical, plumbing, electrical, and building trade finals clear in sequence. SFFD signs off on sprinkler/alarm work where applicable. Any Planning conditions of approval are confirmed satisfied. DBI final building inspection closes the permit and — on substantial additions and new-dwelling-unit projects — issues a Certificate of Final Completion (CFC) or, for new occupancy, a Certificate of Occupancy. Cosmetic remodels close at permit final only, without a formal CFC issuance.

    A finaled DBI permit plus a clean CFC (where applicable) is what future buyers, insurers, title companies, and the SF Assessor-Recorder all require. An open permit that never finals is a chronic title-search flag on SF real estate — unpermitted or un-finaled work discovered at closing can reprice the transaction, lose the buyer, or trigger DBI enforcement. SF's aggressive code-enforcement posture, paired with a hot real-estate disclosure regime, makes close-out discipline especially important. We close the paperwork the month the project ends, file any HPC CofA final documentation if one applied, confirm Rent Board compliance on rent-stabilized buildings, and archive the complete permit history for the homeowner's records. Clean close-out is what distinguishes a finished SF project from a perpetually pending one.

Cost · 2026 San Francisco bands

What an SF remodel actually costs in 2026

Remodel costs in San Francisco are a function of six inputs: labor rate, material cost, permit-and-regulatory overhead, existing-conditions complexity (especially on Victorian and Edwardian housing stock), preservation overhead on historic-district and HPC-reviewed parcels, and — on multi-unit buildings — Rent Ordinance tenant- habitability and relocation costs. SF sits at the top of the US labor-cost pyramid: skilled framing labor runs $85–$130 per hour loaded; CSLB C-10 licensed electricians $135–$225; CSLB C-36 licensed plumbers $150–$245. The rates reflect SF’s cost of living, a tight construction labor market, and California prevailing-wage practices on any project receiving public funds or rent-control passthrough.

Permit-and-regulatory overhead in SF is significantly higher than comparable US cities. A typical $150,000 kitchen remodel with plumbing, electrical, and gas work carries $8,000–$22,000 in DBI permit, plan- check, and trade-permit fees, plus $3,000–$15,000 in Planning review fees if §311 notification or HPC review applies. A §317 demolition-control finding can flip a $15K soft-cost line into a $75K-$200K entitlement line if the project needs a full Conditional Use Authorization. HPC CofA review on historic-district blocks adds $5,000–$25,000 in architect and filing fees plus 8-20 weeks of carrying cost. Soft-Story Retrofit projects carry their own permit-fee schedule. California Title 24 2025 energy- compliance and the SF Green Building Ordinance layer additional compliance costs on every permit.

California property tax under Proposition 13 is the counterweight — base-year values reset only on change of ownership, so a $400,000 remodel on a long-held SF home does not flow into next year's tax notice. A substantial addition or new-construction permit can trigger a partial reassessment on the improvement value under R&T Code §70, which the SF Assessor- Recorder calculates on the improvement alone rather than resetting the whole parcel. Capital-improvement passthroughs under the SF Rent Ordinance are a separate line for rent-stabilized buildings; the Rent Board caps and depreciates these, so they do not reimburse the full project cost. We flag both in every cost conversation so homeowners understand the carrying-cost side of an SF remodel.

Existing-conditions complexity is where SF’s pre-1940 housing stock surprises first-time renovators. A Mission Dolores Victorian built in 1895 with pier-and- post foundation on bay-mud fill, 60-amp service from a single-pole drop, knob-and-tube on all three floors, cast-iron drain stacks corroded to the horizon, lead paint on every original molding, and asbestos-containing plaster throughout does not remodel on the same budget as a 2005 SoMa condo. Baily's consultation surfaces these conditions from photos, the address’s DBI permit history, and the SF Planning GIS overlay set before a bid is issued. We would rather raise the scope honestly at the consultation than deliver a lowball bid that explodes on change orders when the pier-and-post leveling reveals a rotted girder the homeowner did not know existed.

Historic-district and preservation overlays are the third SF cost reality that lead-gen platforms routinely miss. An Alamo Square or Pacific Heights Victorian facade restoration is not a paint job — it’s a months-long carpentry exercise using species-matched redwood, period-appropriate profiles, and HPC-approved paint schemes. Original wood windows typically must be restored rather than replaced; a CofA for aluminum or vinyl replacement windows will be denied. Facade materials removal and replacement follows a documented in-kind standard. Interior gut work behind an HPC- protected facade is permissible but the facade itself is typically off-limits to visible alteration. These constraints add 20-40% to exterior scope line items on most Article 10 buildings.

Here is what the real cost bands look like in San Francisco in 2026, by project type, for work priced by a CSLB Class B GC with SF-area experience, proper DBI permits and Planning coordination, closed-out inspections, HPC CofA where applicable, and a 1-year workmanship warranty:

  • Cabinet-and-countertop kitchen refresh (no plumbing or gas moves, OTC permit path): $55,000–$110,000, 6–10 weeks site time.
  • Mid-tier kitchen remodel (new cabinetry, island, appliance package, relocated plumbing, Standard Plan Review): $125,000–$245,000, 14–22 weeks.
  • High-end kitchen remodel (custom millwork, stone slab counter with full-height backsplash, Sub-Zero /Wolf/Miele package, structural beam for open plan with Complex Plan Review): $275,000–$485,000, 20–34 weeks.
  • Guest bathroom refresh (new tile, vanity, fixtures, retain plumbing rough, OTC track): $38,000–$78,000, 5–8 weeks.
  • Primary spa bathroom (walk-in shower, freestanding tub, double vanity, reconfigured plumbing, proper waterproofing): $85,000–$185,000, 10–16 weeks.
  • Soft-story retrofit (mandated, 5-10 unit building, steel-moment frames + shear walls + tie-downs): $65,000–$325,000, 14–28 weeks.
  • Detached ADU / backyard cottage / garage conversion (state ADU statute, no §311 issues): $185,000–$385,000, 24–44 weeks.
  • Residential addition (single-story, Standard or Complex Plan Review, §311 noticed): $225,000–$550,000, 32–60 weeks.
  • Whole-home Edwardian or mid-century gut renovation (MEP, insulation, structural upgrade, finishes): $325,000–$850,000, 36–64 weeks.
  • Victorian whole-home restoration (HPC CofA, facade restoration, foundation bolting, MEP, interior gut): $520,000–$1,450,000, 52–88 weeks.
  • Pacific Heights or Russian Hill high-end addition with HPC review and full §311 process: $1,200,000–$3,800,000, 60–120 weeks.

These bands reflect the midpoint of completed SF project data, cross-checked against the AskBaily cost-research database and DBI public permit record. They assume CSLB Class B pricing with properly licensed C-class subcontractors, proper DBI permits, a 1-year workmanship warranty, and — where relevant — a closed-out HPC Certificate of Appropriateness and Rent Board sign-off on rent-stabilized buildings. Shared-lead-marketplace bids frequently come in 25–45% below these bands by omitting permits, skipping asbestos abatement, using unlicensed trades, substituting non-original materials in historic districts, or cutting workmanship warranty to zero. The difference shows up at the first DBI inspection, the first HPC photograph review, or the first time a foundation bolt that was never installed causes a floor to shift after the first winter storm.

After the project · warranty + insurance + resale

What happens after the DBI permit is finaled

Most homeowner conversations about an SF remodel focus on the build. The conversations that should have happened earlier focus on what happens after the DBI permit is finaled. Four buckets matter: warranty coverage, insurance posture, SF Assessor interaction under Proposition 13, and future-resale paper trail. Baily is trained on all four because they are where unlicensed and lead-gen projects fail SF homeowners in year two, year five, or during the estate-planning or sale cycle.

Warranty: an AskBaily-matched SF GC carries a 1-year full workmanship warranty on every project. California statutory protections layer on top: Civil Code §896 et seq. (the Right to Repair Act, also known as SB 800) governs residential construction defect claims on new construction and substantial additions, with specific notice-and-opportunity-to-repair procedures before litigation. California’s 10-year statute of repose under Code of Civil Procedure §337.15 applies to major structural, mechanical, plumbing, waterproofing, and foundation defects. Unlicensed work significantly complicates SB 800 claims and typically forfeits the mechanics-lien remedy entirely.

Insurance: a finaled DBI permit, a CSLB-licensed GC, and a closed-out set of trade inspections preserve homeowner insurance coverage. An unpermitted SF renovation risks coverage voidance in the event of any loss traceable to the unpermitted work — electrical fire, plumbing flood, foundation movement, seismic damage traced to an undocumented addition. California FAIR Plan, the insurer of last resort for high-wildfire-risk and difficult-to-underwrite properties, specifically excludes unpermitted improvements from its already-limited coverage envelope. Standard SF homeowner insurance underwriters routinely request permit history during policy rewrites and can non-renew over open or missing permits. CSLB-licensed contractors carry required general liability as a condition of licensure.

SF Assessor interaction: California Proposition 13 caps annual property-value increases at 2% on established base-year values, and a remodel on a long-held SF property does not reset the base-year value. A substantial addition or new-construction permit does trigger a partial reassessment on the improvement value under Revenue & Taxation Code §70 — the Assessor calculates the value added by the new construction and adds it to the existing assessment, leaving the original base year intact on the pre-existing structure. Homeowners often underestimate this because a $400K permit does not flip the whole parcel to current market value; it adds $400K-ish of assessed improvement on top of the existing Prop 13 base. For rent-stabilized multi-unit buildings, capital-improvement passthroughs are a separate line administered by the Rent Board rather than the Assessor.

Resale: California Civil Code §1102 et seq. requires a seller’s Real Estate Transfer Disclosure Statement (TDS) on every residential sale, covering known defects, prior alterations, and permit status. An unpermitted kitchen, an open DBI permit that never finals, a missing HPC CofA on a historic-district alteration, or an undocumented soft-story retrofit failure can all reprice or break an escrow. SF title companies routinely refuse to close on a home with visible unpermitted work, and post-2021 SF lender overlays on non-conforming improvements are tightening. A permit history finaled with DBI, closed with a Certificate of Final Completion where applicable, archived with the HPC CofA where one applied, and documented through the Rent Board on rent-stabilized buildings, is the cleanest possible documentation for a future sale. We build that paper trail by default.
