Kings County, CA Accessory Structures: Tiny Homes (2026)

In the unincorporated areas of Kings County, how a tiny home is regulated depends on its construction. A tiny house built on a permanent foundation is treated as a dwelling or accessory dwelling unit and must meet the California Building or Residential Code adopted in the Kings County Code of Ordinances Chapter 5 (Buildings and Structures) plus the zoning standards in the county Development Code. Manufactured and mobile homes are addressed in the county's Mobile Home Information handout issued by the Community Development Agency's Building Division, and state law (Health and Safety Code provisions for manufactured housing) allows certified manufactured homes on permanent foundations in many residential districts. A movable tiny house on wheels can qualify as an accessory dwelling unit where it meets the ADU definition in California Government Code Section 66313, which defines an ADU as an attached or detached residential dwelling unit providing complete independent living facilities on a lot with a proposed or existing primary residence; a junior ADU alternative is capped at 500 square feet and must be contained within a single-family residence. RVs and park-trailers used as permanent dwellings are generally not allowed as primary residences outside an approved park. Because placement, foundation, and district rules vary, confirm specifics with the Kings County Community Development Agency.
