What Affects Garage Conversion Cost in Los Angeles?
- Permit path: converting to an ADU (with kitchen, bath, separate entrance) triggers Title 24 and ADU plan check; non-ADU office/bedroom conversions are faster and cheaper.

- Electrical panel: most garages need a 100A → 200A panel upgrade ($3k–$6k) to support a kitchen and HVAC.
- Bathroom addition: adding a bathroom requires sewer/water connection and adds $12k–$25k.
- Floor leveling: LA garages often have a sloped slab for drainage — leveling adds $2k–$6k.
