Published 2026 rebuild figures for Los Angeles range from about $400 to $1,100 per square foot, and they genuinely disagree. For Altadena, one widely cited source publishes $400 to $500 per square foot while another publishes $650 to $750 for the same market in the same year. There is no single defensible number. What decides yours is lot complexity, how much fire hardening the site requires, finish level, and whether you hire locally or from the Westside.

What it costs
| What | Typical Los Angeles range | Notes |
|---|---|---|
| Altadena, per GreatBuildz (updated Oct 2026) | $400 to $500 / sq ft | Basic $300-$450, mid custom $450-$600 |
| Altadena, per Benson Construction Group (2026) | $650 to $750 / sq ft | Local lump-sum, straightforward lots |
| Altadena, Westside contractor quotes | Around $900 / sq ft | Reported 20 to 40% above local pricing |
| Stick-built, per Letter Four | $640 to $710 / sq ft | Not tied to a specific neighbourhood |
| ICF construction, per Letter Four | $580 to $650 / sq ft | Competitive once hardening is counted |
| Modular, factory cost only | Around $430 / sq ft | Excludes foundation, crane, utilities, site work |
| LA flat lot, production or catalog plans | $650 to $850 / sq ft | Per Benson, mid-2026 |
| LA hillside custom | $1,000 to $1,400+ / sq ft | Per Benson, mid-2026 |
| Soft costs on top | 15 to 25% | Design, engineering, fees, utilities |
Read the disagreement before you read the numbers
We have put competing figures in the table above rather than picking one, because picking one would be dishonest. For Altadena in 2026, published per-square-foot figures differ by 50 to 70 percent between credible sources. Letter Four's stick-built range lands near the higher band. GreatBuildz sits well below it.
That spread is not sloppiness. It reflects real differences in what is being measured: whether soft costs are included, whether the lot is flat or hillside, whether the home is production or architect-designed, what finish level is assumed, and whether the contractor is a local Altadena firm or a Westside builder pricing a commute. Anyone who hands you one number for a fire rebuild without asking about those things is guessing.
Our advice is to treat every published per-square-foot figure, including the ones on this page, as a way to sanity-check a bid rather than as a budget.
What makes a rebuild cost more than a normal new house
- Fire hardening. Building to the wildland-urban interface standard adds roughly 5 to 15 percent across the whole project, and it is not optional
- Site conditions after a fire. Slope stability, retaining walls, utilities that were destroyed along with the house
- A tight labour market. Thousands of homes competing for the same trades in the same two areas at the same time
- Soft costs that can exceed $40,000 in permits and fees alone before any waiver
- Hillside and geologically sensitive parcels, which carry a premium everywhere in Los Angeles and more here
Against that, there are real reliefs: plan check and permit fees are suspended for owners who held the property on the fire date, and the state waived the solar and battery requirements and the 2025 code changes for residential rebuilds, other than fire-safety standards.
Where rebuilds actually stand
In Pacific Palisades, roughly 1,862 permits had been applied for and 1,317 issued as of early October 2026, with about 1,126 structures under construction and around 50 homes finished. Roughly 2,000 parcels had no permit submitted at all.
In Altadena and the unincorporated county, the county's own recovery dataset showed 2,216 single-family building permits issued and 188 homes completed as of late October 2026, with 1,909 in construction or completed. Across all structure types the county had issued 3,902 permits.
The pattern in both places is the same. Permits and starts are moving quickly. Completions are not. If you are early in this process, the people ahead of you are mostly still building.
What officials say is actually holding things up
Money, more than permits. Supervisor Kathryn Barger has said the significant remaining barriers are financial and that many residents lack the capital to move forward, worsened by delayed insurance payouts. Builders report applicants abandoning plans once real costs come in, which means permit counts overstate progress.
There is a counter-argument from federal officials that local permitting is the bottleneck, and reporting in early 2026 found a 49-day average from application to permit in the Palisades. Both things are true at once: the process is slow and the funding gap is slower.
The gap between your insurance and your rebuild
This is the number that decides most projects. Published analyses have put the average Palisades shortfall at roughly $600 per square foot, around $1.5 million on a typical home, and practitioners describe roughly half the rebuild cost falling on the owner as a normal outcome, rising to 40 to 60 percent on complex sites.
We have not independently verified those figures and you should not plan against them. What they tell you directionally is that the question is not only what a rebuild costs, it is what your policy actually pays. The page on the insurance gap goes through the coverages that move that number.
How we price it
We walk the lot, look at what survived, read your insurance documents and your adjuster's estimate, and build a line-item number against a specific design. Then we tell you what the gap is before you commit to drawings rather than after.
If the gap cannot be closed, we will say so early. That is a more useful answer than a cheap per-square-foot figure that falls apart at bid.

Questions
Why is there no single cost per square foot?
Because credible sources disagree by 50 to 70 percent for the same market, and they disagree because they are measuring different projects. A flat Altadena lot with a catalog plan and a steep Palisades parcel with a custom design are both fire rebuilds and they are not the same product.
Does fire hardening really add that much?
Published estimates put it at 5 to 15 percent of overall cost. It covers the roof assembly, ember-resistant vents, ignition-resistant exterior materials, enclosed eaves, multi-pane glazing and decking. The requirements come from California's wildland-urban interface standards, which were consolidated into their own part of the building code effective January 2026.
Do I have to install solar?
A July 2025 state executive order exempted rebuilds of substantially damaged or destroyed homes in Los Angeles and Ventura counties from the solar and battery storage requirements, while keeping the solar-ready requirements. LA County's implementation also lets rebuilds use the 2022 code rather than the 2025 edition, except for fire-safety standards. Confirm current eligibility with the county, because executive orders can change.
How long will it take?
Published practitioner estimates run 18 to 30 months from design through completion for a custom rebuild, once financing and lot conditions are resolved. Permits are a smaller share of that than most people expect.
Should I use a modular or prefab rebuild?
The advertised modular figure of around $430 per square foot is factory cost only, excluding foundation, crane, utility connections and site work. Once those are added the gap against site-built narrows considerably. On a hillside or hard-access parcel, craning may not be possible at all.
