Garage conversion rules in Tracy, CA — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Garage conversions in Tracy creating an ADU are permitted by right under state law with no replacement parking required. Under SB 987, permits for demolishing a detached garage and building an ADU must be reviewed simultaneously. Building permits are required.
Converting a garage to an ADU in Tracy is processed under state ADU law (CA Gov. Code §65852.2). Under AB 2221 and related bills, garage-to-ADU conversions cannot be denied due to lack of replacement parking. SB 987 (effective Jan 1, 2024) requires Tracy to review demolition permits and ADU permits simultaneously when replacing a detached garage with an ADU. The conversion must meet California Building Code standards for habitable space (insulation, egress, mechanical). Building permits from Tracy Building Safety Division are required. Non-ADU garage conversions (to hobby rooms, home offices) also require building permits for any structural or electrical modifications.
Unpermitted garage conversion: stop-work order, retroactive permit, and fines.
