The Fresno, California zoning code permits use and construction of tiny homes as permanent dwellings and provides for second dwelling units, backyard cottages, and accessory living quarters as a specific type of permitted use in residentially zoned lots. The Fresno ordinance requires a minimum lot size of 6,200 square feet in order to obtain a permit for a second dwelling unit, and a minimum lot size of 6,000 square feet for backyard cottages.
One notable aspect of the Fresno ordinance is the six-component definition of a tiny house it added to its code. Within this definition, the city heightened specific safety requirements by referencing independent product safety standards. The ordinance permits use of a tiny home on wheels as a second dwelling unit, though the wheels must be skirted and the structure not designed to move on its own.
