Summary
Converting a garage to living space in Fresno generally means creating an Accessory Dwelling Unit under Fresno Municipal Code Section 15-2754, and California Government Code Section 66314 bars the City from requiring replacement of the parking spaces lost when a garage is converted to or demolished for an ADU.

Full Breakdown
Fresno Municipal Code (Citywide Development Code) Section 15-2754 treats a converted garage that becomes independent living quarters as a Second Dwelling Unit (ADU). , garage conversions), or allocated to meet the accessory unit's parking, unless replacement parking is provided. However, California's ADU statute preempts this: under Government Code Section 66314, when a garage, carport, covered parking structure, or uncovered parking space is demolished in conjunction with the construction of an ADU or converted to an ADU, the local agency shall not require that those off-street parking spaces be replaced.
A garage converted purely to non-habitable accessory space (no cooking, no independent living) is instead governed by Section 15-2004, which allows an accessory structure to contain a toilet, shower, and sink but prohibits bathtubs and stoves and requires a covenant prohibiting use as habitable space. All conversions require a building permit through the City's Citizen Access portal to verify Building Code compliance (egress, light, ventilation, smoke detectors).
Violations & Fines
An unpermitted garage conversion is a violation of the Building Code and FMC 15-2004/15-2754, enforced by Fresno Building and Safety Services and Code Enforcement. The City may require a permit, correction of unsafe conditions, or restoration of the garage. The City cannot, however, demand replacement parking for a converted garage that creates a qualifying ADU.
