Garage Conversion ADU

Name: Upside ADU
Address: Sacramento, CA, US
Telephone: (916) 282-5283
Price range: $$$

A garage conversion ADU turns an existing attached or detached garage into a legal dwelling. It is usually the cheapest path to a full ADU — from about $95,000 in Sacramento — because it reuses the existing slab, walls, and roof, and no replacement parking is required under California law.

Conversions need egress, insulation, fire-separation, and often a panel upgrade to meet code. Older Sacramento-region neighborhoods like Broderick (West Sacramento) and central Galt have detached garages well suited to conversion.
