A garage conversion reuses an existing garage as a permitted living unit. Bakersfield's ADU FAQ calls interior conversions usually the cheapest kind of ADU, because the slab, walls and roof are already in place.
What does Bakersfield require for a garage conversion?
As of October 2026, the city's ADU FAQ says legally built garages can generally be converted, provided the unit gets a direct outside door and has adequate distance from the property line for fire safety. The conversion must also meet building and energy codes.
Does the conversion need setbacks?
A converted freestanding garage can generally stay where it is. The city's 2024 guide notes the 4-foot side and rear setbacks do not apply to conversions of freestanding structures, and as of October 2026 state law says the same for an ADU created within an existing structure.
Do I have to replace the garage parking?
No. Bakersfield's materials exempt a converted garage from parking, and as of October 2026 state law bars any requirement to replace parking lost to a garage conversion.
What usually has to be upgraded?
- insulation in walls and roof, which matters a lot in valley heat
- a slab that is level and sealed against moisture
- repairs to any damaged framing or roof sheathing
- infill of the garage door opening with a wall, window or door
- plumbing for a kitchen and bathroom, tied to the sewer or septic system
- electrical capacity for cooking and air conditioning
- fire separation from the house if the garage is attached
Can I add space while converting?
A little. As of October 2026, the HCD Handbook allows an ADU converted from an accessory structure to expand by up to 150 sq ft, limited to what is needed for entry or exit. Building a second story over the garage is a different project; the city's FAQ notes it requires a longer Design Review Approval.
What will it cost?
The answer depends on the garage's condition. Use the city's rough $150 to $300 per square foot as a starting range, as of October 2026, and compare against a new build in garage conversion vs. new ADU.
