Selma, CA Accessory Structures: ADU Rules (2026)

The City of Selma permits Accessory Dwelling Units under its municipal code Title 11, consistent with California Government Code Sections 65852.2 and 65852.22. ADUs are allowed on any single-family or multi-family residential lot regardless of parcel size. A detached ADU may be up to 1,000 square feet in floor area. An attached ADU created by adding square footage may not exceed 50 percent of the main residence or 1,000 square feet, whichever is less. There is no square footage cap when converting existing space within the primary dwelling or a detached structure. The minimum ADU size is 150 square feet. Junior ADUs (JADUs) are limited to 500 square feet and must be contained entirely within the existing primary dwelling or attached garage. Single-family properties may have one ADU plus one JADU. Multi-family properties may convert up to 25 percent of existing units or build up to two detached ADUs. For properties that do not meet standard lot coverage, setback, or floor area ratio standards, an ADU of up to 800 square feet is still permitted with minimum 4-foot rear and side setbacks. No additional setback is required when building in the same footprint and dimensions as an existing structure, with up to 150 square feet of additional space allowed for ingress and egress. One off-street parking space is required per ADU unless the property is within half a mile of public transit, the ADU is a garage conversion, or other state exemptions apply. JADUs require no additional parking. ADUs under 750 square feet are exempt from impact and maintenance fees. Fire sprinklers are not required if the primary residence lacks them. Selma offers pre-approved ADU building plans to streamline the process. HOA restrictions prohibiting ADUs on single-family properties are void under California law.
