Why Are ADUs a Smart Strategy in Garden Grove?

Garden Grove actively supports new ADUs through a city ADU program. A dedicated ADU portal and pre-approved plan options make it easier for homeowners to move from idea to building permit.
Detached ADUs commonly target about 800 square feet on many single-family lots. City handouts reference 800 sq. ft. as a typical detached ADU size, giving owners a clear benchmark when planning a one-bedroom or small two-bedroom unit.
Reduced 4-foot side and rear setbacks protect buildability. State-backed ADU rules allow many new ADUs to use 4-foot side and rear yard setbacks, which can unlock space behind existing homes that previously felt too tight to develop.
Multifamily sites can unlock extra rental doors. Updated state law allows certain multifamily properties to add interior ADUs in unused areas and up to two detached ADUs, increasing income potential without a full redevelopment.
