“Parking replacement: the law changed in 2020. If your garage is within ½ mile of transit or in a single-family zone, you do NOT have to replace the parking you're removing with the garage conversion. This is a common contractor myth that deters homeowners from projects that would otherwise pencil out financially. Check your specific parcel at LADBS.org.”
Specify your HVAC system early: a mini-split heat pump is almost always the correct choice for a garage conversion ADU, not an extension of the main house duct system. The mini-split gives the ADU independent climate control, doesn't affect the main house HVAC balance, and is energy-efficient. Budget $3,000–5,000 for the unit and installation.
The most common garage conversion mistakes in Highland Park are: selecting a contractor based on price alone without verifying CSLB license and insurance, approving change orders verbally rather than in writing, and starting work before permits are issued. All three create financial and legal exposure that's avoidable with careful contractor selection and contract management.
