Garden Grove, CA Building Setbacks & Zoning: Lot Coverage Limits (2026)

020(A) sets lot coverage at 50% and, separately, maximum front-setback coverage at 50%. Footnote 3 to the table defines lot coverage as including all buildings and structures, both primary and accessory, plus required uncovered parking areas, while specifically excluding uncovered swimming pools and permeable or semi-permeable recreational surfaces from the count. Footnote 4 addresses the front-yard hardscape cap: driveways and pedestrian walkways count toward the 50% front-setback coverage limit, except for the portion of a driveway that leads directly into a private garage or legally converted garage, which gets a flat exemption of 200 square feet for a one-car garage, 400 for a two-car garage, 600 for a three-car garage, and 800 for a four-car garage.

030(A)(3) layers on a project-review criterion for any new construction, addition or detached structure: the combined footprint of the primary structure, accessory structures, driveways and uncovered parking cannot exceed 50% of total lot area, and if that threshold is not met, the City Manager or designee must deny the plans outright rather than grant a discretionary exception. 050(B)(4)) carries a different, more permissive 60% lot coverage figure limited to that specific overlay corridor between Newhope Street and Brookhurst Street, not the citywide R-1 standard.
