Are You Eligible to Build?
California's housing laws have streamlined the ADU approval process. Many single-family properties may qualify for a detached ADU, garage conversion, or Junior ADU (JADU), subject to local city requirements. Review current regulations through the California Department of Housing and Community Development (HCD) ADU Guide.
