FAQ
How much does a garage conversion cost in Los Angeles?
Most garage conversions in Los Angeles run $100,000–$190,000 depending on plumbing, ceiling height, foundation condition, and finishes. These are editorial estimates — actual quotes vary.
Do I have to replace the parking I lose?
No. California law prohibits cities from requiring replacement parking when a garage is converted to an ADU.
Is my garage suitable for conversion?
Most attached and detached garages can be converted, but a contractor will check the foundation, ceiling height (7'6" minimum in living areas), and utility access. Older garages sometimes need foundation or slab work, which affects cost.
Do garage conversions need permits in Los Angeles?
Yes — converting a garage into living space always requires permits, even though the building already exists. Complete applications must be decided within 60 days under state law. LADBS plan check for standard-plan ADUs can be as fast as one day; custom designs typically take 2–5 months through design and permitting.
How long does a garage conversion take?
Typically 1–3 months of design and permitting plus 2–5 months of construction — noticeably faster than building a detached ADU from scratch.
