On January 7, 2025, the Eaton Fire tore through Altadena and the surrounding foothills, destroying 9,419 structures and damaging 1,076 more. It was one of the most destructive wildfires in Los Angeles County history, and nearly two years later, rebuilding is still complex, slow, and expensive for most families.
Progress is real but uneven. By late September 2026, LA County had issued more than 3,600 building permits in the Eaton burn area, while just under 200 of the nearly 7,000 destroyed housing units had been fully rebuilt. The biggest obstacles haven't changed: confusing permit paths, insurance shortfalls, and construction costs that have climbed well above pre-fire levels.
This guide covers what Altadena homeowners need to know right now: the County permit process and its newer fast-track options, like-for-like rules, fire-hardening and code requirements, realistic costs, the insurance and funding deadlines coming up in late 2026 and early 2027, and a realistic timeline. We update it as rules and numbers change.
At Alto Builders, we're a licensed Design & Build firm (CSLB #1118841) currently designing, permitting, and building Eaton Fire rebuilds in Altadena. This guide draws on that work and on the official sources linked throughout.
What's new since our March 2026 edition: LA County's self-certification pilot for plans, SB 1090's pause on large lot splits in Altadena (signed September 30, 2026), new smoke-damage and ALE protections signed September 15, 2026, SBA's final loan extension, and the November 30, 2026 deadline for SCE's compensation program.
Most of Altadena is unincorporated Los Angeles County, not a city. Your rebuild permits go through LA County Regional Planning (zoning review) and then LA County Public Works / Building & Safety (construction permits). If your parcel is inside Pasadena city limits, Pasadena's own process applies instead.
Regional Planning reviews your site plan, footprint, setbacks, and height for conformance with the applicable standards. For like-for-like rebuilds, the County targets about two weeks for this review. Non-like-for-like projects take longer and may need more rounds of corrections.
With zoning cleared, you submit architectural drawings, structural and civil engineering, and Title 24 energy documentation for plan check. Fire Department, Public Health, and other clearances run alongside this phase.
Applications are filed as a Disaster Recovery Rebuild (CREB) application through EPIC-LA, the County's online permit portal. You can also get in-person help:
LA County's Building Plan Self-Certification Pilot lets eligible licensed architects and engineers certify that plans meet code, skipping full County plan check. The County audits at least 20% of self-certified plans, and one licensed professional takes responsibility for the whole plan set. Hillside and other geologically sensitive lots don't qualify, and Planning, Fire, and Public Health clearances are still required. For a straightforward lot with an experienced design team, this can cut weeks off plan check.
Fee relief: The County doesn't waive rebuild permit fees outright. In June 2025 the Board of Supervisors approved fee deferrals and refunds for owner-occupants in unincorporated areas whose homes were destroyed. Rentals and commercial properties are excluded. Ask about it at the One-Stop center when you apply.
Whether your project qualifies as like-for-like is the biggest factor in how fast it moves through permitting. Decide this early, before design gets far along.
A like-for-like rebuild reconstructs essentially the same size, location, and use as what stood before the fire. In the Eaton Fire area, LA County allows the footprint to grow by up to 10% or 200 square feet, whichever is greater, without triggering full zoning review.
Like-for-like rebuilds still must meet the current California Building, Fire, and Health & Safety Codes. You keep the old footprint but build to modern safety standards.
A larger home, a new layout, or a new location on the lot makes your project non-like-for-like, which means:
| Factor | Like-for-Like | Non-Like-for-Like |
|---|---|---|
| Size change allowed | Up to 10% or 200 sq ft (whichever is greater) | Any size (subject to zoning) |
| Zoning compliance | Not required | Full Title 22 compliance |
| Altadena CSD requirements | Not required | Required |
| Front yard setback (R-1) | Match original | 20-foot minimum |
| Zoning review timeline | ~2 weeks (target) | Several weeks to months |
| Building Code compliance | Required | Required |
| CEQA review | Exempt (up to 110% footprint and height) | May apply |
Many Altadena owners worry about developers buying burned lots and packing in units. SB 1090, signed September 30, 2026, pauses SB 1123 multi-unit lot splits in Altadena ZIP codes 91001 and 91003 for applications filed from October 1, 2026 through early 2030. Applications filed before October 1 aren't affected, and SB 9 lot splits and ADUs remain available to homeowners.
Our recommendation: If getting home quickly is the priority, like-for-like is the fastest path, and the 10% or 200 sq ft allowance often covers a modest bedroom or bathroom addition. If you want a substantially different home, budget for a longer permit timeline and bring the builder into design early so the plans match your budget.
Every Altadena rebuild, like-for-like or not, must meet modern wildfire construction standards. Altadena sits in a Wildland-Urban Interface (WUI) area, which triggers Chapter 7A of the California Building Code.
Under Executive Order N-29-25 (signed July 7, 2025), fire rebuilds may be designed to the 2022 California Building Code instead of the newer 2025 edition. The order also exempts rebuilds from the rooftop solar and battery mandate, though homes must still be solar ready (reserved roof area and electrical capacity for a future system). A later order, EO N-37-25, lets owners whose insurance includes code-upgrade coverage choose the current energy code instead. Confirm the code edition for your project with Building & Safety before design is finalized.
California requires automatic fire sprinklers in all new single-family homes, so every Altadena rebuild needs them. Budget for the system and, on some lots, a larger water meter or service line to supply it.
Under EO N-4-25, as clarified by EO N-20-25, rebuilds in the same location within 110% of the original footprint and height are exempt from the California Environmental Quality Act, which avoids a lengthy environmental review.
The State Board of Forestry voted in August 2026 to adopt "Zone 0" rules limiting combustible materials within 5 feet of homes in high fire hazard areas, but the regulations still need state approval and are not in effect as of October 2026. We recommend designing rebuilds to be Zone 0 ready anyway (gravel or hardscape at the foundation, no wood fencing or mulch against the house), because the rules are expected to come back and insurers are already asking about it.
The upside: Fire-hardening adds cost, but it also makes your new home far more resistant to the next fire than the one you lost, and it can help with insurance eligibility and discounts.
Rebuilding in Altadena costs significantly more than it did before the fire. A USC analysis published October 2026 puts construction at roughly $500 to $700 per square foot after the fire, up from $300 to $400 before it, driven by labor and material demand from thousands of simultaneous rebuilds plus new code requirements.
| Category | Cost Range |
|---|---|
| Standard rebuild (builder-grade finishes) | $450–$550 / sq ft |
| Mid-range custom home | $550–$700 / sq ft |
| Luxury / hillside construction | $700+ / sq ft |
| Design & engineering (architecture, structural, civil, Title 24) | $20,000–$100,000+ |
| Soil & geotechnical reports | $3,000–$8,000 |
| Utility connection (SCE undergrounded service, where required) | $20,000–$40,000 |
| Contingency (recommended) | 10–20% of total budget |
For a typical 2,000-square-foot home, construction alone runs roughly $1.0 million to $1.4 million. Soft costs (design, engineering, surveys, soil reports, utilities) push many projects higher, and hillside lots with retaining walls or caissons add more.
Most Altadena homeowners are rebuilding with less insurance money than the rebuild costs. In United Policyholders' 12-month survey of fire survivors (March 2026), 69% reported being underinsured, by an average of $247 per square foot, and 69% reported delays in claim payments. USC researchers estimate the average gap between payouts and rebuild costs at almost $550,000.
A public adjuster or insurance attorney can help you challenge a low replacement-cost estimate. The funding options below can help close what's left.
Several deadlines land between now and early 2027. Missing them can cost you real money, so put these on your calendar. We're builders, not attorneys or financial advisors, so confirm the details with your insurer, lender, or attorney.
California requires insurers to provide at least 24 months of ALE after a declared disaster, with up to 12 more months if delays are beyond your control (permit backlogs, contractor availability). Your policy's dollar limit can still run out first. Request an extension in writing before your 24 months end, document every delay, and contact the California Department of Insurance if you're refused.
Southern California Edison's program closes November 30, 2026. As of August 2026 it had made more than 2,450 offers totaling over $830 million. Filing a claim doesn't waive your rights, but accepting an offer requires signing a release, so have an attorney review any offer before you sign.
Under SBA's final extension (July 2026), home-loan borrowers have 24 months from loan authorization to draw funds, and loans can be increased by up to 20% of verified physical damage to pay for mitigation such as fire-hardening.
Altadena Land Initiatives Corp.'s Rebuild Gap Program, backed by the Altadena Builds Back Foundation, offers 0% loans repaid later from an Edison settlement, a sale, or a refinance. Borrowers must use one of the program's vetted builders.
A wildfire recovery package signed September 15, 2026 includes AB 1642 and AB 1795 (effective January 1, 2027), which require insurers to cover lead and asbestos testing and remediation for smoke-damaged homes in the fire area and keep paying ALE until the home is safe to live in. AB 1847 extends mortgage forbearance for LA fire survivors to 24 months.
SBA builder self-certification: Under an SBA rule published January 29, 2026, SBA borrowers whose permit applications have been pending more than 60 days can have their builder certify code compliance to SBA. The rule is contested by California and other states, and County inspections and a certificate of occupancy still apply, so talk to your lender and the County before relying on it.
Plan on roughly two to two-and-a-half years from the fire to move-in for a typical rebuild, or about 14 to 24 months from the day design starts. With debris removal largely complete, design and permitting are now where most of the time goes.
| Phase | Duration | Running Total |
|---|---|---|
| Design & engineering | 3–6 months | 3–6 months |
| Permitting (zoning + plan check) | 2–6 months | 5–12 months |
| Site prep & foundation | 2–3 months | 7–15 months |
| Framing & systems (MEP) | 3–4 months | 10–19 months |
| Finishes & landscaping | 3–4 months | 13–23 months |
| Final inspections & certificate of occupancy | 2–4 weeks | ~14–24 months from design |
Soil and site conditions. County-commissioned testing found that 45% of tested destroyed Altadena lots not yet cleaned by the Army Corps had lead above state residential screening levels. Testing your soil before you build is strongly recommended, especially if you have kids or plan a vegetable garden.
Design and engineering is where many homeowners underestimate the time. Even a like-for-like rebuild needs new architectural plans, structural engineering, Title 24 energy calculations, and often a geotechnical report.
Permitting depends on your path. Pre-approved plans and self-certification can shorten it. Non-like-for-like projects, oak trees, and hillside lots lengthen it, and some same-footprint rebuilds have still taken close to 10 months to clear every agency.
Construction typically runs 9 to 14 months depending on size, finishes, and site. Utility coordination, including SCE's undergrounding work in parts of Altadena, can add time at the end if it isn't started early.
Pro tip: Start your utility service requests and soil testing during design, not after permits. They run on their own clocks and are common causes of late-stage delays.
We also recommend staying connected with neighbors and local groups. The Altadena community has been remarkably organized in sharing contractor experiences, pooling information, and advocating for policy changes like SB 1090.
No. Most of Altadena is unincorporated LA County, so rebuild permits go through LA County Regional Planning and Public Works, filed on EPIC-LA or at the One-Stop Permit Center at 464 W Woodbury Rd. Parcels inside Pasadena city limits follow Pasadena's process instead.
Yes, within limits. In the Eaton Fire area, a like-for-like rebuild can grow by 10% or 200 square feet, whichever is greater, without meeting current zoning. Anything larger must meet current zoning, the Altadena Community Standards District, and a 20-foot front setback.
Under Executive Order N-29-25, Eaton Fire rebuilds may use the 2022 California Building Code and are exempt from the rooftop solar and battery mandate, though they must be solar ready. Chapter 7A wildfire standards and fire sprinklers still apply.
California requires at least 24 months of additional living expenses after a declared disaster, plus up to 12 more months when delays are beyond your control, but your policy's dollar limit can run out sooner. Ask your insurer for an extension in writing before January 7, 2027, and contact the California Department of Insurance if you're refused.
The filing deadline is November 30, 2026, and filing alone doesn't waive your right to sue. Accepting an offer requires signing a release, so have an attorney review any offer first.
SB 1090, signed September 30, 2026, pauses SB 1123 multi-unit lot splits in Altadena ZIP codes 91001 and 91003 for applications filed from October 1, 2026 into early 2030. Applications filed before October 1 aren't affected, and SB 9 lot splits and ADUs are still allowed.
Plan on roughly two to two-and-a-half years from the fire for a typical rebuild, or 14 to 24 months from the start of design. Pre-approved plans and the County's self-certification pilot can shorten the permitting stage.
