This is our directory of CSLB license-verified ADU builders serving Los Angeles. Every name on it cleared our vetting checks before it ever reached a homeowner. Request a free intro and we'll unlock the shortlist — then match you to the right fit.
We match you with vetted, California-licensed ADU builders in your area — no guesswork, no cold-calling contractors.
Anyone can search "ADU builder near me" and get 400 results, ads first. This directory is the opposite: a short list of builders we've already license-verified for you.
1-800-ADU-Pros is a referral and pre-qualification service — not a contractor. We don't hold a construction license and we don't build anything ourselves. What we do is vet builders so you only ever talk to pros who are actively CSLB-licensed, bonded, and insured, with their license number on file and shown on their profile. Construction is performed by independent California-licensed contractors.
We keep the builder names behind a quick intro request for one reason: it lets us match you to the right fit for your zone, lot, and budget — and protect our builders' time — instead of handing every visitor a cold list. Answer a few questions, qualify, and the full directory unlocks instantly. See exactly how we vet every builder.
No builder appears here until they clear all four checks. We re-verify license and bond status on an ongoing basis.
We confirm a current, active California State License Board number in the right classification (typically Class B General Building) — and re-check that it stays active.
Every builder carries the required $25,000 contractor's bond, plus general liability and active workers' compensation coverage for their crews.
We review CSLB complaint and disciplinary history and look for verifiable, recently completed LA projects you can confirm on the public permit record.
We screen for real Los Angeles permitting fluency — ZIMAS, ePlanLA, LADBS Standard Plans, and your zone (R1 / RD2 / R3).
