California Regulations: Counties & Municipal Zoning Guide
Understanding where Amish tiny cabins are allowed in California depends on both county and city regulations. California does not have a single statewide tiny house law — each of the state’s 58 counties and their municipalities set their own rules on minimum square footage, foundation requirements, and where tiny homes can be placed. Many rural counties offer more flexible zoning and placement options, particularly in unincorporated areas. Others defer building and zoning authority to local cities and communities. In contrast, suburban and urban municipalities often enforce stricter zoning, including minimum dwelling sizes ranging from 150 to 1,200+ square feet, foundation requirements, and occupancy classifications. Some areas may also regulate tiny homes as accessory dwelling units (ADUs) or recreational vehicles depending on placement and use. Because rules vary widely by location, it’s important to verify requirements with local authorities. The guide below provides a county overview and municipal references to help you confidently plan and place your tiny cabin in California.
