Are the attached adu builders in San Bernardino, CA licensed and vetted?

Yes. Every attached adu builder we list in San Bernardino, CA has an active, verified CSLB license (typically Class B General Building) and has cleared our red-flag screening before we'll introduce them. We're a referral and pre-qualification service, not a contractor, so the work is performed by the independent licensed builder we match you with.

Can I use a attached adu ADU in San Bernardino, CA as a short-term rental?

Not in Los Angeles. The city prohibits using an ADU as a short-term rental — any stay under 30 days (Airbnb-style) is not allowed. ADUs are intended for longer-term housing, and a verified builder in San Bernardino, CA can walk you through the local occupancy and rental rules before you build.
