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

010(E), "Height Limits," states residential buildings must comply with the Table of Building Requirements but in no case exceed 35 feet, unless the code specifies otherwise. 020(A) confirms the specific numbers: main structures are capped at 35 feet and accessory structures at 17 feet. Fire or parapet walls, skylights, towers, flagpoles, chimneys, smokestacks and radio masts may be built above the height limit only in conjunction with an approved development plan or a conditional use permit; the code separately blocks penthouses or roof structures intended to add habitable floor space above the limit, carving out a narrow exception only for religious institutions and public, private or parochial schools building a unique structure, tower or spire under a conditional use permit.

030(F) adds a companion rule specific to the R-1 zone: non-habitable features like fire or parapet walls, skylights, flagpoles, chimneys and wireless masts may be erected 15 feet above the height of the structure they are attached to, without triggering the conditional use permit process required for freestanding towers. 030(D)(3), matching the main table's accessory figure.
