Fremont, CA Accessory Structures: ADU Owner Occupancy (2026)

Many California cities historically required an owner to occupy either the main house or the ADU as a condition of approval, a holdover that state ADU law has steadily stripped away. Fremont's current ordinance codifies that removal directly: Sec. ' That means an investor-owned single-family lot, a rental home with a tenant in the main house, or a property owner who never sets foot on site can still obtain a ministerial ADU permit and keep the unit rented out indefinitely. This sits within the same subsection block as Fremont's other unit-level ADU standards adopted under the 2023-2025 rounds of state ADU conformity ordinances, including the ban on rooftop decks, the two-unit cap on single-family lots (one ADU plus one JADU), and the size limits of 1,000 square feet for an attached addition and 1,200 square feet for a new detached structure.

The JADU provisions in Sec. 005(d) are governed separately by Cal. Gov't Code SS 66333 through 66339, but the owner-occupancy exemption specifically named in subsection (c)(9) applies to ADUs, not JADUs; the state JADU statute still conditions certain JADU permits on owner occupancy of the property, so an applicant building a JADU rather than a full ADU should not assume the same blanket exemption reaches that unit type.
