Santa Clarita, CA Building Setbacks & Zoning: Structure Height Limits (2026)

The same section caps accessory structures at that identical 35-foot limit "without a CUP," which is unusual: most residential zones in the code split main and accessory heights, but UR1 lets an accessory building rise as high as the main house before triggering discretionary review. The section also sets front yard setbacks at 20 feet, side yards at 5 feet each, rear yards at 15 feet, and requires at least 10 feet of separation between main structures. Anyone wanting to exceed 35 feet, for example to build a taller great room, a lookout, or a barn-style accessory structure, must apply for a conditional use permit reviewed by the Planning and Building Services Department, which considers compatibility with the surrounding neighborhood, sightline impacts, and consistency with the General Plan before granting relief.
