ADU Builders

ADU builders, with the license checked first

Most builder roundups rank on photos and review averages. We start with whether the company can legally take your money, then rank what is left.

What we check

Licenses checked live

Every CSLB number is read off the state board's own system on the day we publish, not pulled from a directory. Directories go stale, and a stale license record is how homeowners get hurt.

Failed licenses are named

A builder whose license comes back suspended, revoked, expired or missing is excluded from the ranking, and we say who and why rather than quietly leaving them out.

No paid placement

No builder pays to appear, pays for a position, or is told in advance that they are on a list. There are no vetted-partner programs and no referral fees.

Ratings are dated

Review scores move. Every rating on every page carries the date it was collected, and where we could not verify a number it says Not found rather than showing a zero.
