Berkeley FAQ

Can I park my tiny home on wheels in my Berkeley backyard?

Not for full-time dwelling. THOWs are RVs under California law and cannot be used as permanent residences on residential property. Short-term storage may be allowed with setback compliance.

Do tiny homes on foundation need full foundations?

Yes. To qualify as an ADU, the tiny home must sit on a permanent engineered foundation (slab or pier) meeting CRC. Skirted trailer setups do not qualify.

Livermore FAQ

Can I park a tiny home on wheels in my Livermore backyard?

Short-term storage is allowed, but full-time occupancy of a THOW as a residence is not permitted under Livermore's RV and zoning rules.

Is a foundation tiny home legal as an ADU?

Yes, if it meets California Residential Code and Livermore's ADU standards (minimum size, plumbing, egress, energy).
