How to Convert Your Garage to an ADU: 15 Crucial Questions
Homeowners everywhere are seeing the huge potential that’s sitting at the end of their driveway: garage conversions.
1. How much will it cost to convert my garage to an ADU?
Garage conversions are the cheapest way to build an ADU—and offer the greatest ROI. While a new 500SF stand-alone unit in Southern California can run $160,000 or more, a 400SF garage conversion starts at around $90,000.

Stick-built ADUs usually take between nine and fourteen months to complete. This starts from the first talks with your designer to the completion of the habitable unit. Garage conversions can be much faster, typically around six to seven months.
