Altadena rebuild permits, step by step.

Start here: the One-Stop center

LA County runs an Altadena One-Stop Recovery Permitting Center (464 W. Woodbury Rd., Suite 210) where Planning, Building & Safety, Public Works, and Fire staff coordinate rebuild applications under a unified process. You can walk in during business hours or work through EPIC-LA, the county's online permitting system, where you can also track your application's status.

The like-for-like pathway

Rebuilding what you had — up to 110% of the destroyed home's size — qualifies for a streamlined path that bypasses discretionary review. Go beyond the allowed size or change the use, and the project moves into the general review process with more steps and more time. This fork is one of the first decisions worth making deliberately, because it shapes your timeline, your budget, and your design freedom. County guidance: recovery.lacounty.gov/rebuilding.

Programs that can shorten the path

• Self-certification pilot: licensed architects and engineers can certify plan compliance with building codes, skipping parts of the traditional plan-check queue. Details at the county's self-certification program page.
• Pre-approved standard plans: the county maintains a catalog of pre-approved home and ADU designs that have already cleared zoning and code review — homeowners using one pay only for site-specific review. Note: pre-approved plans cannot be customized without returning to the general process.
• Permit fee waivers: available for owner-occupants who owned their property before January 7, 2025 — ask the One-Stop center about eligibility.

What your plans must include

Altadena's fire-area rebuilds must meet Chapter 7A (wildland-urban interface) construction standards — ember-resistant vents, ignition-resistant exterior assemblies, and related hardening measures — plus the Altadena Community Standards District's design standards and current building, residential, and green codes. A design team that works in these requirements daily will draw them in from the start rather than fixing plan-check corrections later.

How long does it take?

County reporting through 2026 has put average rebuild-permit approval around five months, with published analyses noting timelines lengthening as application volume grows. Individual timelines vary widely with pathway (like-for-like vs. changed design), completeness of the application, and site conditions — treat any number as a planning assumption, not a promise, and check the county's current figures at the One-Stop center.

Where ROAM fits

ROAM Design Studio prepares and shepherds the permit package — including self-certification where applicable — and ROAM Builders (CSLB Lic. #1151324) builds to it, as one accountable team. If you want a second opinion on a permit path you've already started, we're glad to give one.
