Garden Grove, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Garden Grove's Zoning Code Title 9.16 establishes maximum building heights for each zoning district. In R-1 (Single-Family Residential) zones, the maximum height is 35 feet or 2 stories, whichever is more restrictive. Height is measured from the finished grade at the building perimeter to the highest point of the roof, including parapets and rooftop equipment. R-2 and R-3 zones may allow taller structures with additional stories. Commercial zones typically allow 35-50 feet depending on the specific district. Chimneys, antennas, flagpoles, and mechanical equipment may exceed the height limit by a specified amount with approval. Accessory structures in residential zones are limited to 15 feet in height and one story. The height limit helps preserve neighborhood character, ensure adequate light and air, and maintain privacy between neighboring properties. ADUs (Accessory Dwelling Units) under California state law may be up to 16 feet in height per Government Code Section 65852.2, which may preempt local height limits for qualifying ADU projects. Height variances require Planning Commission approval through a public hearing with demonstrated hardship findings. Slope considerations may affect effective height on graded lots.
