Sacramento County
Vineyard is an unincorporated CDP in Sacramento County, so tiny home rules are set by the Sacramento County Zoning Code (Title 5) and Building Code, not a city ordinance. Permanent-foundation tiny homes that meet the 2022 California Building Code may be permitted as Accessory Dwelling Units (ADUs) under Sacramento County Zoning Code Section 5.4.5.F. Tiny homes on wheels (THOWs) are treated as recreational vehicles and cannot be occupied as a permanent residence outside a licensed RV/mobile home park.

Sacramento FAQ
Can I live in a tiny house on wheels in the City of Sacramento?
Not on a private residential lot. The City of Sacramento has not adopted a tiny-house-on-wheels ordinance, so movable tiny houses remain classified as recreational vehicles under California Health and Safety Code 18010 and Title 25 CCR and may only be occupied in a licensed RV park or mobilehome park.
Is a tiny home legal as an ADU in Sacramento?
Yes, when built on a permanent foundation and permitted as an Accessory Dwelling Unit under SCC Chapter 17.228, Article XIV. The structure must meet the 2022 California Building Code as adopted in SCC Title 15 and the accessory-structure setbacks in SCC 17.624.050.
Does Sacramento allow tiny homes like West Sacramento does?
No. West Sacramento's Ordinance 24-9 (adopted 2025) legalized tiny homes on wheels as dwellings up to 399 sq ft in most residential zones. The City of Sacramento has not enacted a parallel ordinance, so THOWs are still treated as RVs there.
What happens if I park a tiny house on wheels and live in it on my Sacramento property?
Code Enforcement can cite the property under SCC Chapter 8.04 for unlawful occupancy and zoning violations under Title 17, with administrative fines and an order to remove or vacate the unit.
Vineyard FAQ
Can I put a tiny home on my Vineyard property?
Yes, if it sits on a permanent foundation, meets the 2022 California Building Code, and complies with Sacramento County Zoning Code § 5.4.5.F as an ADU. Tiny homes on wheels cannot be used as a permanent residence on a residential lot in unincorporated Vineyard.
Do I need a permit for a tiny home ADU in Vineyard?
Yes. Sacramento County requires building, plumbing, electrical, and zoning approvals through the County Building Permits and Inspection Division. Submit plans showing foundation, setbacks (4 ft min rear/side), height (16 ft detached max), and ADU size limits under § 5.4.5.F.
Is there a minimum size for a tiny home in unincorporated Sacramento County?
Yes. Under the California Residential Code adopted by Sacramento County, a habitable room must be at least 120 sq ft (CRC R304) and an efficiency dwelling unit must be at least 220 sq ft. The county has no smaller tiny-house-specific minimum.
