In the first week Archistar's AI plan-checking tool went live in Los Angeles, it reviewed 38 Palisades rebuild submissions. Twenty-two failed. Not for structural deficiencies, not for fire-rating violations, not for setback encroachments into somebody's yard. For trees. Fifty-eight percent of homeowners submitting plans to rebuild their burned homes had not indicated mature trees on their site drawings, a requirement that city staff themselves did not realize would be an issue until the software flagged it in a two-minute scan that would have taken a human draftsman two days. A separate discovery was just as telling: a setback rule had been on the books for four years, authored by a planner who no longer worked at the department, silently rejecting applications that nobody knew how to fix until an algorithm surfaced it.
That is the kind of story people want to hear right now, an algorithm cutting through bureaucracy so families can get home faster, and the technology behind it is genuinely impressive.
It is also the wrong story.
Permits Are Moving
Los Angeles has issued 3,106 rebuilding permits out of 6,612 applications received, according to Governor Newsom's office, a remarkable pace by any measure of American disaster recovery. After the Camp Fire destroyed Paradise in 2018, Butte County managed 385 permits in the first year. In Maui, construction on the first home did not begin until nearly a year after the fire. LA's rebuilding permits are moving roughly three times faster than comparable single-family permits issued in the five years before the January 2025 fires.
Archistar's eCheck AI, provided free through a partnership between the state, Steadfast LA, LA Rises, Autodesk, and Amazon, is part of what is making that possible. Its software uses computer vision and machine learning to check architectural drawings against local building and zoning codes before homeowners formally submit to the LA Department of Building and Safety, compressing a two-day manual review into a two-minute automated scan that catches compliance gaps buried in code amendments nobody reads. Austin adopted the same tool in October 2024 after a three-month pilot. Honolulu is next.
The Materials Are Not the Problem
The Insurance Institute for Business & Home Safety and Headwaters Economics published a detailed cost comparison in Fall 2025, analyzing a representative 1,750-square-foot single-story home in Altadena. They priced every component required for wildfire-resistant construction under three standards: California's CWUIC Part 7 (which became law on January 1, 2026), IBHS Wildfire Prepared Home Base, and IBHS Wildfire Prepared Home Plus.
Building to the state's mandatory standard adds $13,070 in materials over traditional non-fire-resistant construction, covering flame-and-ember-resistant vents, fire-rated gypsum wallboard on exterior walls, dual-pane tempered windows, metal gutters, and a five-foot noncombustible zone of rock mulch and metal fencing around the home. Going further to the IBHS WFPH Plus standard, which requires enclosed eaves, noncombustible soffits, and double-tempered windows, adds $15,242 total.
Thirteen thousand dollars on a half-million-dollar home is 2.6 percent, not trivial, but nowhere near the number keeping families out of their neighborhoods.
Then the researchers did something unusual: they compared their RSMeans national pricing database against what contractors could actually buy at Home Depot in Altadena, and current material costs came in $2,418 less than RSMeans assumed. Materials are not getting more expensive. In some categories, they are cheaper than the models predict.
| Standard | Material Cost | Premium Over Traditional |
|---|---|---|
| Traditional (no fire resistance) | $59,223 | Baseline |
| CWUIC Part 7 (CA mandatory) | $72,293 | +$13,070 |
| IBHS WFPH Base | $68,099 | +$8,876 |
| IBHS WFPH Plus | $74,465 | +$15,242 |
Where the Money Actually Goes
That same 1,750-square-foot model home, which IBHS priced at $500,000 using national averages of $285 per square foot, is actually costing Altadena families between $787,000 and $1.14 million because local organizations involved in the rebuild reported actual costs of $450 to $650 per square foot.
Between the national-average estimate and the actual cost sits a gap of $287,000 to $640,000 per home. Materials are not responsible for any of it, as IBHS confirmed explicitly.
Labor is.
"Particularly in a post-disaster context, labor and contractor overhead costs can greatly exceed material costs," the IBHS report states. "This is particularly true in Los Angeles, where labor shortages are hampering the recovery and significantly inflating rebuilding costs."
Researchers at Ohio University put it more bluntly: "Stricter federal immigration policies and enforcement likely amplified these constraints by limiting the available workforce." According to NAHB CEO Jim Tobin, builder lending rates remain at 10 to 12 percent despite Federal Reserve cuts, in what was already "the most expensive market to build in the country."
Three Hundred Homes a Month
The math required for recovery is unforgiving. ULI Los Angeles, UCLA, and USC calculated that rebuilding 80 percent of destroyed homes by mid-2028 requires starting roughly 300 homes per month, with 60 to 70 percent beginning construction in 2026. That rate exceeds what any California community has sustained after a wildfire. Santa Rosa rebuilt 80 percent of the 1,500 homes destroyed in Coffey Park within three years, which remains the gold standard. LA's fire destroyed more than 16,000 structures.
AI can check building plans in two minutes, but it cannot produce the framers, electricians, and plumbers needed to execute those plans at a pace that has no precedent in American disaster recovery. ClaimArchitect, a startup founded by fourth-generation LA builder Kambiz Kamdar, is using AI document analysis to generate builder-verified rebuild valuations for fire victims, and in early cases their 55-to-75-page reports have found discrepancies of $700,000 to $1.7 million between insurance adjuster estimates and what it actually costs to rebuild. That technology is helping homeowners fight for fair payouts, and it works, but the money is secondary to the labor because you can win the insurance fight and still wait 18 months for a framing crew.
Fair Counterargument
Permitting was the binding constraint in the first year of recovery. Without AI-accelerated plan review, LA would still be processing paper applications at pre-fire staffing levels while 16,000 families waited. Archistar solved a real problem, and what happened next is exactly how systems improvement is supposed to work: you break one bottleneck and the next one reveals itself. Faster permitting made the labor shortage visible; it was always underneath.
That does not change the conclusion; it sharpens it. LA now has the permits and the plans, but what it does not have is the workforce, and there is no AI tool on any startup's roadmap that produces a licensed electrician in two minutes.
If You Are Rebuilding
Use the Archistar eCheck tool before you submit plans, because it is free, catches compliance failures that would bounce your application, and is available at start.archistar.ai for both LA City and County. Do not let the code upgrades scare you into thinking wildfire-resistant construction will bankrupt you. Materials add $13,000, not $130,000, and many components cost the same as traditional alternatives because the labor to install a solid-core door is identical to the labor for a hollow-core one.
Get an independent rebuild cost estimate before accepting your insurer's number. ClaimArchitect is one option, and any licensed general contractor who will produce a line-item estimate and sign it is another, but either way the insurance gap is real and can run into seven figures.
Lock in your contractor early. At 300 homes per month, every licensed crew in the LA basin will be committed for years, and if you can start construction in 2026 you should, because waiting makes the labor problem worse as more approved permits chase the same shrinking pool of workers.
Limitations of This Analysis
IBHS's cost analysis uses a specific 1,750-square-foot model home in Altadena, and actual Palisades and Altadena homes vary enormously in size and architectural complexity, meaning larger or more custom builds will face proportionally different material premiums. Calculating the $287,000 to $640,000 labor gap relied on the difference between RSMeans national averages and locally reported costs per square foot rather than matched-pair comparisons of identical homes built in different labor markets. Immigration enforcement's impact on construction labor supply is asserted by Ohio University researchers based on macroeconomic analysis, not from a direct count of workers who left LA-area job sites. Archistar's eCheck tool remains in pilot, and the 38-submission results cited are from its earliest week of operation. ClaimArchitect's reported discrepancies come from early cases with an undisclosed sample size, and no publicly available data disaggregates residential construction labor shortages by metro area in real time.
