Tiny Homes: Folsom vs McClellan Park

Can I live in a tiny house on wheels in my Folsom backyard?

Not as a permanent residence. THOWs are classified as RVs and can only be occupied up to 30 days per year on a residential lot. For permanent occupancy, build a foundation-based ADU instead.

What's the smallest ADU I can build in Folsom?

There's no strict minimum size in state law, but it must meet habitability code — at minimum a habitable space with bathroom, kitchenette, egress, and utilities. Most permit-approved tiny ADUs are 150-400 sq ft.

Can I live in a tiny home at McClellan Park?

Only on a parcel that allows residential use under the Sacramento County Zoning Code and the McClellan Park Specific Plan. Much of McClellan Park is business-park, industrial, or airport-zoned. Where residential ADUs are allowed, Zoning Code § 5.4.5.F controls — foundation required, 850–1,000 sq ft max, 4-ft side/rear setbacks.

Are tiny homes on wheels allowed in McClellan Park?

No, not as permanent dwellings. Sacramento County treats THOWs as recreational vehicles and prohibits permanent RV occupancy on residential lots outside a licensed RV or mobile home park. There is no county-adopted THOW ordinance.

Who do I contact about tiny home permits in McClellan Park?
