Los Angeles County Building Permit Timelines & Delays
If you are rebuilding in Altadena, most of the permit wait is on your side of the counter. Los Angeles County’s rebuild dashboard showed fire-rebuild cases averaging 32 days in County review against 122 days waiting on the applicant’s response, as reported in April 2026, and the median Altadena rebuild took 155 days to reach a permit at the end of March 2026. The January 2025 Eaton Fire damaged or destroyed 6,921 structures in unincorporated Altadena and Kinneloa Mesa.
Los Angeles County permitting, the figures
The key published figures for this jurisdiction — each cited to its official source.
What the data shows
Most of the wait for a County fire-rebuild permit is time the file spends with the applicant, not the County: cases averaged 32 days in County review against 122 days waiting on the applicant’s response, so a complete first submittal and fast answers to plan-check comments are the biggest schedule lever a builder controls (LA County rebuild dashboard, as reported by the Los Angeles Times, 2026).
The measured clock got longer: the median time to an Altadena rebuild permit rose from 127 days in December 2025 to 155 days at the end of March 2026, while Public Works’ stated 5–10-day plan-review turnaround (July 2026) is a per-review timeline, not the full application-to-permit time (Los Angeles Times, 2026; LA County Executive Office, 2026).
A like-for-like Eaton Fire rebuild is exempt from current zoning rules, though not from current building, fire and health codes, and may grow by 10% or 200 square feet, whichever is greater, under an interim ordinance that is the County’s final allowed extension and lapses in summer 2027 (LA County Ord. 2026-0024U, 2026; LA County Recovers, 2026).
Owner-occupants rebuilding a fire-destroyed single-family home, or its garage or ADU, can defer County zoning, plan-review, permit, inspection, Fire Department and public health fees, with no deadline to apply; LLC-owned, rental, multifamily and commercial projects do not qualify, and the County reported more than $17 million deferred or refunded by May 19, 2026 (LA County Recovers, 2026; LA County Board of Supervisors, 2026).
Most delay accumulates before technical review
The data points to the same lever everywhere: most delay accumulates before technical review, in completeness and resubmittal cycles. Permavia's Permit Review Diagnostic checks your plans against applicable codes and common reviewer issues before you submit — so your package is more likely to clear on the first pass.
Los Angeles County permitting: FAQ
Who issues building permits in unincorporated Los Angeles County, like Altadena?
Los Angeles County Public Works, Building and Safety Division, which serves unincorporated communities through ten district offices, alongside 12 offices that serve contract cities (LA County Public Works). Zoning review and the fire-rebuild Disaster Recovery Permit come from the Department of Regional Planning (LA County Regional Planning, 2026). An address inside the City of Los Angeles is permitted by the City’s Department of Building and Safety, and Pasadena and Malibu publish their own rebuild trackers (LA County Recovers, Permitting Progress Dashboard).
How long does an Eaton Fire rebuild permit take in Altadena?
The median was 155 days from application to permit at the end of March 2026, up from 127 days in December 2025, and the County’s dashboard showed fire-rebuild cases spending about 32 days in County review against 122 days waiting on applicants (Los Angeles Times, Apr 1, 2026). Public Works describes 5–10-day plan-review turnarounds and 48-hour inspection turnarounds as its stated timelines, not measured averages (LA County Executive Office, Jul 16, 2026).
Which building code applies in unincorporated Los Angeles County in 2026?
The County’s 2026 Building, Residential, Electrical, Plumbing, Mechanical, Green Building and Existing Building codes took effect January 1, 2026 for applications filed on or after that date (LA County Public Works). In state-designated fire hazard severity zones and County Fire wildland-urban interface areas, the County’s 2026 plan-review checklist applies the 2025 California Wildland-Urban Interface Code: a Class A roof, vent mesh with 1/16 to 1/8 inch openings, and multipane exterior glazing with at least one tempered pane (LA County Public Works, VHFHSZ Plan Review 2026). Residential Eaton and Palisades fire rebuilds may follow the 2022 California building standards instead of the 2025 edition under a state executive order, except for the 2025 code’s “fire and public safety requirements” from the State Fire Marshal and its minimum flood-elevation standards, which still apply (Executive Order N-37-25, Nov 24, 2025, which replaced that paragraph of the July 2025 order N-29-25; LA County Recovers).
Are permit fees waived for Altadena fire rebuilds?
They are deferred, and refunded if already paid, rather than waived; the County says the deferred fees will not be collected from owners. The Board approved the program on June 17, 2025, and it covers zoning, plan review, permit, inspection, Fire Department and public health fees for a replacement single-family home destroyed or irreparably damaged in the Eaton or Palisades Fire, including accessory structures rebuilt with it and a standalone ADU the owner lives in while the home is rebuilt, when the applicant both owned and lived on the property before January 7, 2025. The County’s page lists no deadline to apply and most refunds take two to four weeks (LA County Recovers, Fee Deferrals and Refunds). Under the interim ordinance, the Disaster Recovery Permit filing fee for a like-for-like rebuild is $1,320 (LA County Ord. 2026-0024U).

All figures on this page are drawn from Implementing the Los Angeles County Disaster Recovery Rebuild Authority (Board motion, May 19, 2026), Los Angeles County Board of Supervisors (Supervisors Barger and Horvath). Board motion reporting more than 3,300 rebuild permit applications, more than 2,300 residential permits issued, more than 1,200 homes under construction in the Eaton Fire area and more than $17 million in fee deferrals and refunds, as of May 19, 2026; supplemented by the County’s LA County Recovers rebuild pages and Ordinance No. 2026-0024U. Read the Board motion (PDF, LA County Board of Supervisors). Specific tables, reports, and pages are cited inline with each figure above.
Two kinds of numbers appear here. Measured: the 155-day median and the 32-versus-122-day split come from Los Angeles Times reporting on County permit records and the County’s rebuild dashboard (spring 2026), because the dashboard itself could not be read directly, and the Times did not say whether the dashboard averages cover Altadena only or all County fire-rebuild cases; the 3,600-permit count and completions after May 2026 come from news reporting (Inside Climate News, October 2026). Targets: the 5–10-day plan-review turnaround is a County-stated timeline, not a published average. Two leads were corrected: the County code in force is the 2026 edition (the 2023 edition was superseded January 1, 2026), and no County 30-day rebuild review target could be found, so none is cited. The interim ordinance is its final allowed extension under Gov. Code §65858; its title gives August 22, 2027 as the end date, but its Section 6 ends it one year after its July 28, 2026 adoption, and County Counsel’s June 8, 2026 transmittal letter gives July 28, 2027, the earlier of the two dates; Executive Order N-37-25 (November 24, 2025) replaced the building-code paragraph of the July 2025 order N-29-25 and sets no end date; the County still lists N-29-25 among current rebuild exemptions as of October 28, 2026. SB 1090, a new state planning and zoning law that news reports say limits high-density development in Altadena, was signed September 30, 2026 (Office of the Governor), but its official text could not be read, so its terms are not described here.
