Eaton Fire, Altadena
Rebuilding in Altadena after the Eaton Fire
Altadena is unincorporated, so your rebuild is permitted by Los Angeles County, not a city. A like-for-like rebuild can grow by up to 10% or 200 square feet, whichever is greater, and gets a ministerial Disaster Recovery Permit; anything larger follows current county zoning, including the Altadena community standards. LyteMods rebuilds homes here in non-combustible light-gauge steel, starting with 480 W Palm St.

Two ways to rebuild in Altadena
The like-for-like path rebuilds what was legally there: same use, same location, and up to 10% or 200 square feet larger in floor area, height, or footprint, whichever is greater. It runs under the county's Eaton Fire interim ordinance as a ministerial Disaster Recovery Permit, with no hearing, and current zoning rules do not apply. The building, fire, and health codes still do. The ordinance now runs through August 22, 2027, which the county describes as its final extension.
Build bigger or different, and current county zoning applies, including the Altadena community standards: a 20-foot minimum front yard for non-like-for-like rebuilds, a 30-foot height limit (35 feet on lots of 20,000 square feet or more), 23 feet within 15 feet of a property line, two stories, and house size and lot coverage each capped at a quarter of the net lot area plus 1,000 square feet.
County tools that can shorten the process
- Pre-approved standard plans: a county catalog of home plans for the Eaton area that already meet current zoning and building codes, with a parcel viewer to see them on your lot.
- PreCheck: an AI zoning review of your site plan for R-1 lots in unincorporated Altadena, with results in up to 10 business days, attached to your permit application.
- Self-certification: registered California architects and engineers can certify code compliance for a replacement home, garage, or ADU instead of a full county plan check. The county audits at least 20% of these, and it is not allowed in geologically sensitive areas.
- The number to know: the county reports an average of 133 business days to permit, of which 29 are county review and 105 are waiting on the applicant's corrections. Complete, clean submittals are the part you control, and it is the part we manage.
Site issues specific to Altadena lots
- Soil: county Public Health found elevated lead above screening levels on some parcels downwind of the fire. Army Corps soil removal reduced the risk on destroyed lots, but the county still suggests testing and managing surface soil during the rebuild.
- Soils reports: a geotechnical report is not always required for a conventional slab or raised foundation, but it is for caissons, piles, basements, and known geologic hazards.
- Septic: more than 300 destroyed Altadena homes were on septic or cesspools. An existing system can be reused for a like-for-like rebuild if it works, the bedroom count stays the same, and setbacks are met; a sewer connection may be required within 200 feet of a public sewer.
- Power: Southern California Edison plans about 40 circuit miles of underground lines in Altadena's high fire risk areas, and the county notes that owners must grant easements for utility equipment or it cannot be installed.
Adding an ADU to your Altadena rebuild
The county's Eaton rules let a like-for-like rebuild include new ADUs and junior ADUs, provided they meet current zoning, with no replacement parking where an ADU sits over a destroyed garage or carport. Under the Governor's Executive Order N-9-25, a new ADU can be occupied before the rebuilt main house through January 16, 2028, so a family can move home while the house goes up.
Where Altadena's rebuild stands
As of September 26, 2026, Los Angeles County reports 3,671 building permits issued in the unincorporated Eaton burn area (a count that includes repair permits), 2,310 new homes under construction, and 215 completed. Most of the rebuild is still ahead.
What will it cost to rebuild in Altadena?
Based on full-scope rebuild estimates TESH Group companies prepared in Altadena through September 2026, construction typically runs $450 to $550 per square foot with standard finishes, $550 to $675 with upgraded finishes, and $675 to $850 for a custom home. Design, engineering, and permits add about 8 to 12 percent. A hillside foundation adds roughly $75,000 to $200,000, and a basement adds $250 to $400 per square foot. A 2,000 square foot home with upgraded finishes on a flat lot comes to about $1.19 million to $1.51 million all in. Your lot, plans, and finishes set the real number.

A planning estimate built from full-scope rebuild estimates TESH Group companies prepared for homes in Altadena, Pacific Palisades, and Malibu (September 2026). It includes current wildfire code construction. It is not a bid, an appraisal, or insurance advice, and it leaves out demolition, utilities, landscaping, pools, and financing costs. Your real number depends on your lot, your plans, and your finishes.
Built here, not pitched here
480 W Palm St: a steel home standing in the burn zone
Our flagship Eaton Fire rebuild is a 2,789 square foot, four-bedroom home framed in light-gauge steel wall panels made in our factory and assembled on site. The frame went up in February 2026 during a public build demonstration, and KTLA Channel 5 has covered the project.
On the same lot, a steel-framed ADU built years earlier by our sister company ADU Concepts survived the fire.
Why steel for Altadena
- A non-combustible frame takes the structure out of the fuel load in a wind-driven ember fire like Eaton.
- Wall panels are made in our factory while the county reviews your plans; at 480 W Palm they were craned into place over a few days.
- Steel does not rot, warp, or feed termites, and a light, ductile frame performs well in earthquakes.
Steel framing takes the structure out of the fuel load. It does not make a house fireproof, which is why the roof, vents, windows, and siding still follow the wildfire code on every home we build.
How we would build your lot
Many Altadena lots have the street access that suits panelized steel: panels arrive flat on a flatbed and are set with a crane, as at 480 W Palm. Volumetric modules, through Cal Steel Modular, are an option only where the lot and street genuinely allow module delivery.
We can build to a county pre-approved plan, your architect's design, or one of our own plans, such as The Manzanita, about 1,050 square feet and sized for Altadena replacement homes.
Common questions
Rebuilding in Altadena: questions we hear.
- How much does it cost to rebuild a house in Altadena after the Eaton Fire?
- Based on full-scope rebuild estimates TESH Group companies prepared in Altadena through September 2026, construction typically runs $450 to $550 per square foot with standard finishes, $550 to $675 with upgraded finishes, and $675 to $850 for a custom home. Design, engineering, and permits add about 8 to 12 percent. A hillside foundation adds roughly $75,000 to $200,000, and a basement adds $250 to $400 per square foot. A 2,000 square foot home with upgraded finishes on a flat lot comes to about $1.19 million to $1.51 million all in. Your lot, plans, and finishes set the real number.
- Who issues my rebuild permit in Altadena?
- Los Angeles County. Altadena is unincorporated, so Regional Planning handles zoning and Public Works Building and Safety issues building permits, with Fire and Public Health reviews. File at the Altadena One-Stop Permit Center, 464 W Woodbury Rd, Suite 210, or online through EPIC-LA. Properties in Pasadena or Sierra Madre go to those cities instead.
- How much bigger can a like-for-like rebuild be in Altadena?
- Up to 10% or 200 square feet, whichever is greater, in floor area, size, height, or footprint, on the same use and location as the legally established home. Beyond that, current county zoning applies, including the Altadena community standards.
- Is there a deadline to apply?
- The county says like-for-like applications are generally due within two years of the January 7, 2025 emergency declaration, with extensions possible. The Eaton Fire interim ordinance runs through August 22, 2027, and approvals under it must be used by January 7, 2030.
- Do I have to pay county permit fees?
- Not if you owned and lived in the home before January 7, 2025 and are rebuilding it as your primary residence in unincorporated Altadena. The relief covers the replacement home plus garage, ADU, and pool, and it does not apply to rentals, multifamily, LLC-owned, or sold properties.
- Can we live on the property while the house is rebuilt?
- Yes. A new ADU can be occupied before the main house through January 16, 2028 under Executive Order N-9-25, and the same order allows manufactured homes, mobilehomes, and RVs on the lot during the rebuild for three years.
- Should I test my soil before rebuilding?
- County Public Health recommends that owners consider soil testing or consulting an environmental professional, especially on standing-home parcels downwind of the fire, and manage surface soil during construction.
