Permits for garage conversions in Pasadena
Garage conversions require building permits even though the structure exists. California law removes the biggest historical obstacle: cities cannot require you to replace the parking you lose. Complete applications must be decided within 60 days. Typical Pasadena timelines run 2–4 months through design and plan check; historic-property projects should budget extra design time.

FAQ
How much does a garage conversion cost in Pasadena?
Most garage conversions in Pasadena run $100,000–$185,000 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 Pasadena?
Yes — converting a garage into living space always requires permits, even though the building already exists. Complete applications must be decided within 60 days. Typical Pasadena timelines run 2–4 months through design and plan check; historic-property projects should budget extra design time.
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.
