El Monte FAQ
Do I have to replace the parking if I convert my garage to an ADU?
No. Under California Government Code §66314 (the state ADU law) and El Monte's ADU/JADU Program Guidelines, no replacement parking is required when a garage, carport, or covered parking structure is demolished or converted in conjunction with creating an ADU.
Can I convert my garage into a bedroom without making it an ADU?
Only with a permit, and you must provide replacement on-site parking that meets EMMC Title 17 residential parking standards. Most R-1 lots require 2 covered spaces, so a straight bedroom conversion is often infeasible. Converting to an ADU avoids the parking-replacement requirement.
