LA Post-Fire Rebuild — SB 1103 Like-for-Like, CBC 7A WUI, Palisades + Eaton Reality

If you're reading this, you probably lost a home in January 2025. Before anything else: we're sorry. What follows is a working document, not a pep talk. It is the operational and legal reality of rebuilding in Los Angeles County under SB 1103, Governor Newsom's three emergency executive orders, LADBS's tiered plan-check, and the California Building Code Chapter 7A wildland-urban interface requirements that will govern every wall, vent, roof, and window you put back on that lot.

Rebuilding a destroyed home in LA in 2026 is not the same job it was in 2024. The legal pathway is faster if you stay inside the "like-for-like" lane. It is materially slower if you step outside of it. The construction standards are stricter everywhere, and they are stricter still inside the WUI severity zones that cover most of Pacific Palisades and most of the Altadena burn footprint. The costs are higher than pre-fire comps suggest, because WUI compliance, soil work, and insurance-driven "Ordinance or Law" upgrades all stack on top of the baseline.

This guide is reviewed by Netanel Presman, CSLB License #1105249, who has worked Palisades rebuilds on the ground. It is LA-scoped. It is written for homeowners who are either already in the debris-clearance phase or trying to decide whether to rebuild at all.

The January 2025 Palisades + Eaton fire context

The Palisades Fire ignited January 7, 2025 in Pacific Palisades and moved through Temescal Canyon, Sunset Mesa, and portions of Malibu. The Eaton Fire ignited the same week in the foothills above Altadena in unincorporated LA County. Together the two fires destroyed roughly 12,000 residential structures, making this the largest single residential destruction event in modern LA County history. Most of the destroyed properties sit inside either a Very High Fire Hazard Severity Zone (VHFHSZ) or a High Fire Hazard Severity Zone (HFHSZ) under the CAL FIRE Fire Hazard Severity Zone maps¹.

That single fact — that you are almost certainly inside a VHFHSZ or HFHSZ — is the reason the rebuild process looks different from a normal teardown-and-rebuild in Sherman Oaks or Culver City. California Building Code Chapter 7A applies to every new home built inside those zones. There is no opt-out. There is no "it was grandfathered before" argument, because your pre-fire home is gone and what you put back is new construction.

The second fact that governs everything downstream is that both fire footprints received Governor-level emergency declarations in January 2025, which unlocked the three executive orders discussed below and triggered SB 1103's streamlined pathway at LADBS and LA County DPW.

SB 1103 (2024) — what like-for-like exempts from CEQA

California SB 1103 was signed October 2024, a little over two months before the Palisades and Eaton fires. It gave LA County's Board of Supervisors and the City of LA authority to adopt streamlined rebuild ordinances for any residence destroyed in a declared wildfire emergency². The core mechanism is a California Environmental Quality Act (CEQA) exemption for rebuilds that substantially match the pre-fire home in footprint and use.

Inside LA's adopted rebuild ordinance, "like-for-like" generally means:

• The new home sits inside substantially the same footprint as the pre-fire home
• Floor area does not expand more than approximately 10% over pre-fire square footage
• The use stays residential — single-family stays single-family, duplex stays duplex
• Height does not materially increase beyond pre-fire height
• The number of dwelling units does not increase

If you stay inside that envelope, SB 1103 and the local rebuild ordinance exempt the project from CEQA review, exempt it from standard Coastal Development Permit processing during the EO window (for Palisades parcels in the coastal zone), waive most LADBS plan-check fees, defer most impact fees, and drop you into LADBS Tier 1 plan-check with a target 30-day turnaround.

Step outside the envelope and SB 1103 does not apply. You land in standard CEQA, standard plan-check, and standard fee schedules. That is not a death sentence — plenty of rebuilds need more room than the pre-fire layout gave them — but it is a meaningfully different timeline and cost profile.

Governor EOs N-25-24 / N-26-24 / N-27-24 — time-limited streamlining

Governor Newsom issued three emergency executive orders in January 2025 that stacked on top of SB 1103³. The three orders, in rough terms:

EO N-25-24 — Suspended portions of CEQA that would otherwise apply to like-for-like fire rebuilds, waived certain California Environmental Quality Act procedural requirements, and authorized local jurisdictions to bypass discretionary review for qualifying rebuilds.

EO N-26-24 — Temporarily relaxed California Coastal Act review for Pacific Palisades parcels inside the coastal zone, which is the band running roughly from Pacific Coast Highway up to the first ridgeline. Without this order a Palisades coastal-zone rebuild would sit in a 3-to-6-month Coastal Commission queue. With it, coastal-zone like-for-like rebuilds run through the LADBS pathway at similar speed to non-coastal rebuilds.

EO N-27-24 — Authorized debris-removal fee waivers, streamlined contractor licensing for out-of-state firms registered with CSLB under emergency reciprocity, and extended temporary-housing allowances on destroyed lots.

The critical constraint: all three orders are time-limited. The streamlined pathway requires that the rebuild permit be filed within three years of the fire. For the January 2025 fires that deadline runs through approximately January 2028. A rebuild permit filed in February 2028 does not get the EO streamlining, even if the rest of the project is identical to one filed a month earlier. For most homeowners that is plenty of runway. For homeowners still fighting with their insurance carrier or still waiting on a probate or trust issue, the three-year window is a hard constraint to start tracking now.

LADBS Tier 1/2/3 plan-check triage

LA Department of Building and Safety adopted a three-tier plan-check system for fire rebuilds that roughly maps to how much you are changing from the pre-fire home⁴:

Tier 1 — Pre-fire footprint plus up to approximately 10% expansion. Expedited plan-check with a stated target of 30 days. Most CEQA and Coastal Act review is exempted under SB 1103 and the Governor's EOs. Fees are waived or deferred. This is the fast lane and it is real. Homeowners with pre-fire as-builts and clean permit history are closing plan-check inside the 30-day target on a regular basis in 2026.

Tier 2 — 10% to 20% floor-area expansion or modified footprint. Standard plan-check with some streamlining, target 60 to 90 days. Partial CEQA review may apply depending on what changed. Some fees apply. A Tier 2 project is still materially faster than a non-fire-zone standard plan-check, but it is not the 30-day lane.

Tier 3 — More than 20% expansion, significant redesign, or change in use/unit count. Full standard plan-check, target 90 to 180 days. Full CEQA review. Full fee schedule. Coastal Commission review adds 2 to 4 months on Palisades coastal-zone parcels if the project is filed outside the EO window or falls outside the EO's scope.

A point that catches homeowners off guard: architects who know residential work in LA do not automatically know the fire-rebuild tiered pathway. Asking an architect specifically whether the intended design keeps you in Tier 1 versus Tier 2 is a worthwhile first conversation, because a 150-square-foot addition to a 1,500-square-foot pre-fire home is the difference between 30 days at LADBS and 90 days at LADBS.

CBC Chapter 7A WUI construction requirements

California Building Code Chapter 7A is the wildland-urban interface construction chapter. It governs every new home built inside a VHFHSZ or HFHSZ, and it is non-negotiable on a post-fire rebuild⁵. The requirements that most change construction cost and sequencing:

Roofing — Class A fire-rated assembly. Practically that means concrete tile, clay tile, metal, or a qualifying asphalt composition with the correct underlayment. Wood shakes are prohibited. The roof is the single largest ember-capture surface on the house, and the code treats it that way.

Exterior siding — Ignition-resistant. Fiber cement, stucco over metal lath, stone veneer, masonry, metal cladding, or heavy-timber assemblies that meet the ASTM E 2707 or SFM 12-7A-1 standards. Standard wood lap siding does not comply without a fire-rated assembly behind it.

Windows and glazing — Dual-pane with at least one tempered pane. Single-pane annealed glass fails ember exposure quickly and is prohibited. Skylights follow similar rules.

Vents — 1/8-inch corrosion-resistant mesh on every exterior vent, and ember-resistant (baffled) vents on attic and foundation openings that meet ASTM E 2886 or SFM 12-7A-5. The vent spec is one of the most commonly missed items on post-fire plan-check and one of the most common sources of rework at rough inspection.

Defensible space — 100 feet of managed vegetation around the structure, organized into Zone 0 (0 to 5 feet, non-combustible), Zone 1 (5 to 30 feet, reduced fuel), and Zone 2 (30 to 100 feet, managed fuel). Zone 0 in particular got stricter in 2024 and effectively requires a non-combustible perimeter — no wood mulch, no combustible fencing touching the structure, no shrubs against the wall.

Fire sprinklers — Mandatory in all new residential construction in California per CBC §903.2.8 regardless of WUI status. On a post-fire rebuild that means NFPA 13D residential sprinklers throughout, which requires a licensed C-16 fire-sprinkler contractor, a water service upgrade in many cases, and a separate plan-check submittal that runs in parallel with the architectural plan-check.

Foundation-to-wall interface — Either concrete foundation meeting the assembly detail or a fire-rated assembly protecting the first two feet of wall. This is where ember intrusion into the structure most commonly happens and where Chapter 7A is most specific.

The cumulative effect of Chapter 7A is roughly $30 to $70 per square foot of added cost over a non-WUI home of identical design, most of which is materials rather than labor.

Debris clearance — Phase 1 (EPA + Corps) vs Phase 2 (private / CA OES)

You cannot pull a rebuild permit on a parcel that has not completed debris clearance. Debris clearance happens in two phases⁶.

Phase 1 — Hazardous materials. Federal EPA and the US Army Corps of Engineers handle Phase 1 at no cost to the homeowner in declared federal disaster areas. Phase 1 is not optional and cannot be done by a private contractor. It covers asbestos, lead paint, residual household hazardous materials, propane tanks, and electronics. Phase 1 on the 2025 LA fires completed in most neighborhoods by mid-to-late 2025, though some parcels with complex site conditions ran longer.

Phase 2 — Structural debris and soil. Two options. The CA OES opt-in program uses Army Corps contractors to remove structural debris and test soil at no direct cost to the homeowner (costs are billed to insurance up to policy limits, with any shortfall covered by state and federal funds). The private contractor option lets the homeowner hire their own licensed, OES-certified debris contractor, typically when the homeowner wants faster turnaround, specific material salvage (e.g. stone, metal, historic elements), or control over soil-testing scope.

Phase 2 through the CA OES program typically ran 2 to 6 months from enrollment to completion on the 2025 fires. Phase 2 through a private contractor generally ran 6 to 12 weeks from contract signing. Both produce a soil-clearance letter that LADBS requires before rebuild plan-check acceptance.

Homeowners who opted out of both the state program and private Phase 2 — choosing to self-manage — generally stalled. LADBS does not accept rebuild plans without a documented clearance, and self-managed clearance rarely produces the paperwork LADBS needs.

Soil contamination testing + remediation

Soil testing happens at the tail end of Phase 2 and covers the standard post-fire suite: arsenic, lead, mercury, polycyclic aromatic hydrocarbons, asbestos, and (in some Palisades coastal parcels) petroleum-range organics from older fuel-oil heating systems. Testing is typically 4 to 8 weeks from sample pull to final report.

Two outcomes are common:

Clearance with no remediation required. Most parcels in both the Palisades and Eaton burn footprints test clean after Phase 2 debris removal, because the Phase 2 contractor strips the top layer of ash-contaminated soil as part of the clearance scope.

Clearance contingent on spot remediation. Some parcels test hot for arsenic or lead in localized areas, typically under what used to be the garage, the pool equipment pad, or a pre-fire burn pile. Remediation means excavating the affected area to 2 to 4 feet, hauling the soil to a Class 2 or Class 3 landfill, and backfilling with clean import. Cost ranges from $8,000 to $40,000 depending on footprint and haul distance.

The homeowners who have the roughest time at this stage are the ones whose insurance disputes delayed Phase 2 enrollment. Soil contamination gets harder to characterize, not easier, as seasons pass.

Insurance coverage — ALE + DR + PP + Ordinance or Law

The four coverages that matter most on a total-loss fire claim⁷:

Additional Living Expenses (ALE). Covers rent and related costs while you are displaced. California law requires a minimum 24 months of ALE on declared-disaster total losses, and the Governor's EOs extended this further for the 2025 fires. Track the ALE clock carefully: it starts on the fire date, not on the debris-clearance date.

Dwelling Replacement (DR). Rebuilds the home. The critical question is whether your policy has "Extended Replacement Cost" (typically 125% to 150% of stated dwelling limit) or "Guaranteed Replacement Cost" (covers full rebuild regardless of stated limit). Homes insured to their 2020 stated value are almost universally underinsured in 2026 — construction cost escalation plus WUI premium means the 2020 stated limit is often 40% to 60% short of actual 2026 rebuild cost.

Personal Property (PP). Contents. Typically 50% to 75% of DR limit. Requires itemized inventory. This is the claim that drags on longest — most homeowners are still settling PP 12 to 18 months after the fire.

Ordinance or Law coverage. This is the one that matters most for a Chapter 7A rebuild and the one homeowners most often miss. "Ordinance or Law" pays for code-upgrade costs that would not have existed on the pre-fire home — the Chapter 7A upgrades, the fire sprinkler system, the energy code upgrades to current Title 24, the seismic upgrades to current CBC. Typical policies carry $50,000 to $250,000 in Ordinance or Law coverage. On a Palisades rebuild, the real Chapter 7A premium often runs $75,000 to $180,000 for a 2,500-square-foot home, so the Ordinance or Law limit is the line item to check first.

If the policy's Ordinance or Law limit is below what the Chapter 7A upgrades will actually cost, that gap comes out of the homeowner's pocket. This is the single most common financial surprise on a 2025 LA fire rebuild.

Unpermitted additions — the pre-fire paperwork trap

Here is the trap that catches a meaningful share of Pacific Palisades and older Altadena homes: the pre-fire home had additions that were never permitted. A converted garage. A second-story addition from the 1970s. An ADU before the state legalized them. A sunroom off the kitchen.

Under SB 1103 and LADBS's like-for-like rules, unpermitted square footage does not automatically qualify for the exemption. LADBS will typically accept documented pre-fire square footage — assessor records, old appraisals, Google Street View history, insurance photos, previous permits that referenced the expanded footprint — but the burden is on the homeowner to prove it.

Three common outcomes:

Homeowner proves the expanded footprint was either permitted or existed before current permit requirements. Full like-for-like exemption applies to the full pre-fire footprint.

Homeowner proves the expanded footprint existed but cannot prove permits. LADBS typically allows the rebuild at pre-fire footprint but may require the homeowner to treat the previously-unpermitted portion as "new construction" for some Chapter 7A and Title 24 purposes.

Homeowner cannot prove the expanded footprint existed. The rebuild qualifies for like-for-like on the documented footprint only. The undocumented square footage either gets added back as Tier 2 or Tier 3 (losing the 30-day pathway) or gets dropped from the rebuild.

This is why the first conversation with any fire-rebuild architect or contractor should include the question: "What permits do you have on the pre-fire home and what pre-fire documentation can you produce?" Start pulling that paperwork before debris clearance finishes, not after.

Cost reality — $350 to $900 per square foot by Tier plus WUI premium

The 2026 cost bands we are seeing on LA fire rebuilds, hard-cost only (excluding land, architecture, site work, and soft costs):

Tier 1 like-for-like rebuild inside the WUI — $350 to $550 per square foot. Typical 2,500-square-foot Palisades rebuild hard cost lands at $875,000 to $1.4 million. Typical 1,800-square-foot Altadena rebuild hard cost lands at $650,000 to $1 million.

Tier 2 modified-footprint rebuild — $450 to $700 per square foot. The premium over Tier 1 reflects both the slower plan-check and the fact that Tier 2 projects tend to involve more custom design and more structural change.

Tier 3 new-design rebuild — $550 to $900 per square foot. Coastal-zone Palisades parcels with ocean-view orientation, cliffside foundations, or large footprint expansions can run higher. Tier 3 in a coastal zone outside the EO window can cross $1,000 per square foot once Coastal Commission conditions land.

Add 8% to 15% on top of hard cost for architecture, structural engineering, survey, soils, and Title 24 consulting. Add 2% to 5% for LADBS fees where not waived. Add 10% to 20% contingency — fire-zone site work produces more surprises than flat-lot new construction, and Chapter 7A compliance is enforced strictly at rough inspection.

Timeline — 14 to 30 months fire to move-in

A realistic end-to-end timeline for a January 2025 Palisades or Eaton fire rebuild, for homeowners who stayed in Tier 1:

• Month 1 to 3 — Phase 1 debris clearance (EPA + Corps), insurance documentation, architect selection, CSLB B contractor selection
• Month 2 to 6 — Phase 2 debris clearance (CA OES or private)
• Month 5 to 8 — Soil testing and any spot remediation
• Month 6 to 9 — Architectural design, structural engineering, Title 24, fire-sprinkler design
• Month 9 to 11 — LADBS Tier 1 plan-check (target 30 days, real-world often 45 to 60 once revisions land)
• Month 10 to 13 — Foundation, framing, rough trades
• Month 14 to 20 — Finish trades, MEP rough-in, inspections
• Month 18 to 24 — Final inspection, Certificate of Occupancy, move-in

The 14-to-30-month range reflects the difference between a straightforward Tier 1 like-for-like with intact insurance and clean paperwork (14 to 18 months) versus a Tier 2 or Tier 3 rebuild with insurance friction or documentation gaps (24 to 30+ months). The single biggest delay driver in the data so far is not plan-check. It is insurance settlement.

What Baily verifies before any LA post-fire match

Post-fire work is not general contracting. It has its own regulatory stack, its own product knowledge, its own inspection pitfalls, and its own insurance-interaction pattern. Matching a homeowner with a contractor who has never worked inside CBC Chapter 7A or never run a Phase 2 clearance handoff is a meaningful harm, not a small one.

For any post-fire rebuild in LA County, Baily verifies before introducing a contractor:

• Active CSLB Class B license (general contractor) with zero open complaints and zero disciplinary actions tied to fire-zone work
• Three or more closed WUI or Chapter 7A projects in the last 36 months, with photo documentation and permit numbers
• Licensed architect on the team with post-fire experience — at least one closed Palisades, Altadena, Malibu, Woolsey, Thomas, or Camp fire rebuild
• $2 million minimum general liability insurance (the CA post-fire standard; many homeowner policies and lenders require it)
• Fire-sprinkler contractor (C-16) on the team or on call with NFPA 13D residential experience
• Registered LADBS fire-rebuild portal account — a small logistical marker, but an absence means the contractor has not actually run a rebuild through the streamlined pathway
• Debris clearance relationship — either a CA OES-certified in-house capability or a vetted Phase 2 subcontractor
• References specifically from post-fire clients (not general remodel references)

Angi sends your information to twelve strangers. Baily sends it to one fire-experienced CSLB B contractor, verified by Netanel Presman, CSLB #1105249, who has worked Palisades rebuilds on the ground.

FAQ

Does SB 1103 let me rebuild my Palisades home without CEQA review?

SB 1103 (2024) paired with Governor EOs N-25-24, N-26-24, and N-27-24 gives you CEQA exemption IF you rebuild substantially in the same footprint and use as the pre-fire home — "like-for-like" rebuild. Up to approximately 10% floor-area expansion typically qualifies as like-for-like under LA City and County rebuild policies. Larger expansions drop you into standard CEQA review and standard LADBS Tier 2 or Tier 3 plan-check. The streamlining is real but time-limited: rebuild permits must be filed within 3 years of the fire (i.e. through January 2028 for the 2025 fires) to claim the streamlined pathway. Coastal-zone properties in Pacific Palisades have additional Coastal Commission interaction, though the Governor's EOs temporarily relaxed that review too.

My pre-fire home had an unpermitted addition. Can I rebuild at that expanded footprint under like-for-like?

Not automatically. LADBS will consider documented pre-fire square footage — assessor records, old appraisals, Street View history, insurance photos, prior permits — but the burden is on you to prove the footprint existed. If you can prove it, most of the time LADBS allows the rebuild at pre-fire footprint, though the previously-unpermitted portion may be treated as new construction for Chapter 7A and Title 24 purposes. If you cannot prove it, the unpermitted area either gets rebuilt as Tier 2 or Tier 3 (losing the 30-day plan-check lane) or gets dropped from the rebuild. Start gathering pre-fire documentation before debris clearance finishes, not after.

How much does CBC Chapter 7A WUI construction add to the cost of my rebuild?

Roughly $30 to $70 per square foot over a non-WUI home of identical design, most of which is materials rather than labor. On a 2,500-square-foot Palisades rebuild that is $75,000 to $175,000 in added construction cost. This is the number to check against your insurance policy's "Ordinance or Law" coverage limit — that coverage is what pays for code-upgrade costs on a rebuild, and the typical policy carries $50,000 to $250,000. If your Ordinance or Law limit is below the real Chapter 7A cost, the gap comes out of your pocket, which is the most common financial surprise on a 2025 LA fire rebuild.

How long before I can actually pull a rebuild permit?

You cannot pull a rebuild permit until debris clearance (both Phase 1 federal hazmat and Phase 2 structural/soil) is complete and you have a clearance letter from either CA OES or your private Phase 2 contractor. Phase 1 on the 2025 fires completed in most neighborhoods by mid-to-late 2025. Phase 2 through the CA OES program typically ran 2 to 6 months from enrollment; Phase 2 through a private contractor ran 6 to 12 weeks. Soil testing adds another 4 to 8 weeks on the tail. Realistic earliest permit-pull timing for homeowners who enrolled in Phase 2 promptly: 6 to 10 months after the fire. For homeowners still in insurance disputes or still waiting on Phase 2 enrollment, the timeline extends accordingly.

What's the difference between Tier 1, Tier 2, and Tier 3 plan-check at LADBS?

Tier 1 is pre-fire footprint plus up to roughly 10% expansion — expedited plan-check with a 30-day target, most fees waived, most CEQA and Coastal Act review exempted under SB 1103 and the Governor's EOs. Tier 2 is 10% to 20% expansion or modified footprint — standard plan-check with some streamlining, 60 to 90 days, partial CEQA review, some fees. Tier 3 is more than 20% expansion, significant redesign, or change in use — full standard plan-check, 90 to 180 days, full CEQA, full fees, and Coastal Commission review for coastal parcels filed outside the EO window. Your architect should be able to tell you on day one whether your intended design keeps you in Tier 1 or bumps you into Tier 2.
