Book a conversation with Baily online or by phone. Share photos, your address, any prior permit history, deed-restriction status, historic-district status, floodplain status, MUD jurisdiction (if unincorporated), and budget range. Baily returns a rough scope, a cost band, the applicable Houston Public Works permit track, whether Chapter 42 compatibility standards will apply, whether the parcel sits in a Harris County Flood Control District SFHA, whether HAHC review will be required, and whether the project needs TCEQ OSSF sign-off — all in the same session.

Houston remodels bifurcate on seven questions, one more than Dallas: are there recorded deed restrictions on the parcel (roughly 80% of residential Houston has them), is the parcel inside a designated historic district (Houston Heights, Old Sixth Ward, Sam Houston, Broadacres, Avondale, Audubon Place, Courtlandt Place, First Montrose Commons, Westmoreland), is the parcel inside a Special Flood Hazard Area as updated post-Harvey (Buffalo Bayou, White Oak Bayou, Brays Bayou, Greens Bayou, Sims Bayou, Halls Bayou corridors), does the scope trigger Chapter 42 compatibility or setback review, is the parcel inside Houston city limits or inside an adjacent city (Bellaire, West University Place, Southside Place, Hunters Creek Village, Sugar Land, Pearland, Katy, League City — the permit jurisdiction is by parcel, not by mailing address), is the parcel on a MUD rather than City of Houston water/sewer, and does the scope trigger hurricane-uplift hardening under the Houston Fire Code wind-zone framework. Baily answers all seven from the address and photo set alone, so the scope conversation reflects the real permit path — not a best-case fantasy.

Before design begins, pull the recorded deed restrictions from the Harris County Clerk and verify Chapter 42 compatibility against the current lot configuration. Because Houston has no zoning, the deed-restriction covenants govern setbacks, lot coverage, material palette, fence height, accessory structures, paint colors, and sometimes full design review — and they vary block by block. Chapter 42 governs minimum lot size, parking ratios, and compatibility with adjacent properties. A scope that violates either can be stopped by a neighbor's civil suit or by Planning & Development's plan-review desk.

Houston's no-zoning posture is a moat, not a void. Deed restrictions are enforced privately by neighbors, active HOAs (Westbury, Memorial, River Oaks Property Owners, Bellaire Civic Club), and neighborhood associations. Violating a recorded deed restriction — building a detached ADU that a 1962 covenant bans, using composite siding where wood is required, exceeding a 3-foot front-yard fence restriction — exposes the homeowner to injunction, forced demolition at the homeowner's cost, and attorney-fee recovery by the suing neighbor. Chapter 42 is the city-side backstop: minimum lot size rules that prevent a single parcel from being subdivided below threshold, compatibility standards that constrain building lines and rear yards relative to adjacent houses, parking minimums for ADUs. Baily's consultation pulls the deed-restriction document automatically on parcels where it's recorded and flags Chapter 42 applicability against scope — so the design that lands on the architect's desk is already inside the envelope.

If the parcel sits inside a FEMA Flood Insurance Rate Map (FIRM) Special Flood Hazard Area — possible on any parcel near Buffalo Bayou, White Oak Bayou, Brays Bayou, Sims Bayou, Greens Bayou, Halls Bayou, or their tributaries, and on many parcels that moved into the SFHA after the post-Harvey floodplain-ordinance revisions — Houston requires a floodplain development permit, base-flood-elevation certification, and (on substantial improvement scope >50% of pre-project appraised value) full Chapter 19 compliance: lowest-floor elevation to BFE + 2' freeboard. Floodplain determination runs 2-6 weeks on routine scope; substantial-improvement scope adds 12-24 weeks and significant design cost.

A Houston parcel's post-Harvey floodplain status often does not match pre-Harvey intuition. Homes that flooded in Harvey but had never flooded in the previous 40 years, homes that were listed outside the 100-year floodplain before 2017 and inside it after, and homes inside the 500-year floodplain (which Chapter 19 now regulates more strictly than pre-Harvey FEMA alone did) can all carry floodplain development obligations the homeowner didn't know about. The substantial-improvement threshold is defined as any renovation whose value exceeds 50% of the building's pre-project appraised value — a figure Houston homeowners often reach without realizing it because Harris County's land-vs-improvement split on inner-loop parcels heavily favors land. Crossing the substantial-improvement threshold flips the project from 'routine floodplain review' to 'must elevate the lowest floor to BFE + 2-foot freeboard' — a design change that can add $45K-$200K on a typical remodel and 8-16 weeks on the schedule. Baily flags the substantial-improvement math at consultation so homeowners see it before committing to a scope.

The matched Houston GC walks the home, confirms electrical panel capacity, plumbing-stack condition, gas-line material, load-bearing walls, foundation type (slab-on-grade common post-1950, pier-and-beam on older stock, post-Harvey-elevated pier-and-beam in flood-rebuilt homes), expansive-clay soil movement history, asbestos and lead-paint presence on pre-1981 and pre-1978 buildings respectively, humidity and mold history (Gulf Coast-specific), prior Harvey or Imelda flood-damage records, and any existing Houston Public Works permits open or recently finaled. Fixed-fee proposal follows within 5-7 business days.

Houston's pre-1970 housing stock — the Heights, Montrose, East End, Third Ward, Sunnyside, Independence Heights, Acres Homes, Fifth Ward — presents common existing-conditions complications: expansive-clay soil movement under pier-and-beam foundations, 60-100 amp service from rear-lot alley feeds, cast-iron drain stacks corroded at the hub-and-spigot, galvanized water supply, knob-and-tube in pre-1940 upstairs, asbestos in 9-by-9 floor tile and pre-1981 pipe insulation, pre-1978 lead paint that triggers EPA RRP on every dust-generating interior scope, and in flooded homes: residual mold in wall cavities, rotted subfloor never fully dried, salt-water corrosion on pre-Harvey metal fasteners. Post-1970 slab-on-grade Houston housing in Memorial, Westbury, Meyerland (heavily flooded in Harvey), Bellaire, and West University has its own signature complication — post-tension slab cables on post-1975 stock restrict floor cuts. A contractor who skips the walk and bids from photos without reviewing Harvey/Imelda flood-insurance claim history is setting up change orders.

Before a contract is signed, verify each trade subcontractor's state credential: TDLR for electrical (TECL/TECH), HVAC, AC contractor, and irrigator; TSBPE (separate state board) for plumber. Verify the general contractor's Houston Public Works registration on file for the permit class being pulled. Verification is per-project, not per-signup; TDLR and TSBPE rosters refresh daily. The LicenseCard on this page demonstrates the TDLR receipt shape live.

AskBaily's Wave 181 verifier automates TDLR trade-card lookups against the state's public license search; the TSBPE plumbing connector follows the same pattern. The Houston Public Works contractor-registration connector is on the Phase 7.F roadmap — until it lands, Public Works registration is manually confirmed against the iPermits portal on every project. Houston Public Works does not issue a standalone ACD-style HIC card in the Austin mode; instead, registration lives tied to the permit class itself, which means a contractor who has pulled permits in the scope class recently is de-facto registered. Trade credentials that have lapsed, been suspended, or carry unresolved TDLR/TSBPE enforcement actions filter out before the homeowner sees the match.

If the building is individually landmarked or sits inside one of Houston's designated historic districts — Houston Heights (Heights East/West/South), Old Sixth Ward, Sam Houston (Heights), Broadacres, Avondale, Audubon Place, Courtlandt Place, First Montrose Commons, Westmoreland, and others — any visible exterior alteration requires a Certificate of Appropriateness (CofA) from the Houston Archaeological & Historical Commission before Houston Public Works can issue the permit. Staff-level CofA review runs 4-8 weeks on scope that meets published design guidelines; full HAHC hearing extends to 10-16 weeks.

Houston's historic-district review is structurally similar to Dallas or Seattle's but runs faster. The Houston Historic Preservation Office staff prepares the CofA submission package (elevations, materials cutsheets, historic photographs where available) in coordination with the homeowner's architect. Design guidelines are published per-district and govern roof-line, fenestration, materials palette, porch details, and massing. Interior alterations are generally unreviewed unless the interior itself is designated — which is rare. Baily checks historic-district overlay against the Houston Historic Preservation GIS map at consultation, so the CofA clock is sequenced against the Houston Public Works plan-review clock rather than stacked sequentially. An experienced Houston architect can often run CofA and plan review in parallel for a net saving of 4-8 weeks over the sequential path.

The plan set is filed through the Houston Permitting Center's iPermits online portal under the applicable track. Over-the-counter quick-track: same day to 2 weeks for minor scopes. Standard residential plan review for kitchen, bath, or remodel with multi-trade work: 4-8 weeks. Additions and substantial structural work: 8-14 weeks. Two to three review cycles with corrections returned to the architect is typical. Trade permits (electrical, plumbing, mechanical, gas) may file bundled or separately.

Houston Public Works plan review is notably faster than Dallas or Austin for comparable scope and substantially faster than Seattle or San Francisco. Envelope compliance under the Houston Energy Code (2015 IECC with amendments, less strict than Dallas's 2021 adoption) is audited against R-values, window U-factor, duct leakage, and domestic-hot-water envelope; structural calculations for any load-path change require stamped review by a Texas-licensed Professional Engineer; hurricane wind-load compliance on exterior scope adds a structural-attachment review lane. 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 with Houston Public Works Inspection, HFD Fire Prevention (on sprinkler scope), and CenterPoint Energy (gas-meter upsizing) or the Harris County electrical-utility reviewer is the next sequencing task.

With permit in hand and the registered GC holding the job, demolition begins within Houston's construction-noise ordinance hours. Asbestos abatement on pre-1981 materials and EPA RRP lead-safe work on pre-1978 surfaces sequences early. Foundation, framing, MEP rough-in, insulation, drywall, and finishes proceed through Houston Public Works's trade-inspection cadence — typically 10-20 inspections on a standard remodel, more on additions, historic restorations, or floodplain-elevated rebuilds. Hurricane-uplift structural attachment is verified at framing inspection; HFD Fire Prevention signs off on any sprinkler-triggered scope in parallel.

Houston construction is logistically tractable but carries Gulf Coast complications. Expansive-clay soil movement during wet-dry cycles drives foundation-settlement risk on any project that disturbs footing or pier geometry. Summer heat and humidity (95-100F and 70-85% RH June through September) slow crew productivity and compress effective work hours; exterior scope scheduled for October-April delivers cleaner work than peak-summer. Hurricane season (June 1 - November 30) introduces schedule risk: named-storm evacuations or mandatory evacuations can shut down a site for 3-10 days, and post-storm materials-supply disruption can extend. Humidity also drives mold risk on any wall-cavity assembly that isn't sealed and dried correctly — the Gulf Coast assembly physics differ meaningfully from Dallas or Austin. Houston Public Works's scheduling turnaround is typically 1-3 business days through iPermits. Energy-code duct-leakage testing at post-construction is the compliance gate that routinely catches cut corners.

Structural, mechanical, plumbing, electrical, and building-trade finals clear in sequence. CenterPoint Energy confirms permanent gas service; the applicable electrical utility (CenterPoint, or the MUD's utility on unincorporated parcels) energizes permanent electrical service; the City of Houston water department or the applicable MUD confirms meter and backflow where applicable. HFD sign-off on any sprinkler-triggered work. Any HAHC CofA conditions of approval are confirmed satisfied. Chapter 19 floodplain-compliance sign-off is recorded on SFHA parcels. Houston Public Works final building inspection closes the permit and — on new-dwelling-unit additions, ADUs, substantial additions, and changes of use — issues a Certificate of Occupancy. Cosmetic remodels close at permit final only.

A finaled Houston Public Works permit plus a clean Certificate of Occupancy (where applicable) is what future buyers, insurers, title attorneys, and the Harris County Appraisal District all require. An open permit that never finals is a chronic title-search flag on Houston real estate; unpermitted or un-finaled work discovered at closing can reprice the transaction, lose the buyer, or trigger Public Works enforcement. Texas Property Code 5.008 seller-disclosure requirements mean any known permit issue must be disclosed on sale — an undocumented Heights exterior alteration without HAHC CofA, a Brays Bayou SFHA substantial-improvement done without elevation compliance, or a Chapter 42 setback violation becomes a legally disclosable defect. Houston's post-Harvey insurance market additionally scrutinizes permit history hard — underwriters routinely request complete permit records during rewrite, and unpermitted work discovered mid-policy can trigger non-renewal. We close the paperwork the month the project ends, file any HAHC CofA final documentation if one applied, confirm Chapter 19 floodplain-compliance sign-off on SFHA parcels, and archive the complete permit history for the homeowner's records.
