Tehama County, CA Building Setbacks & Zoning: Structure Height Limits (2026)

Tehama County's zoning code sets building height by district. The R-1 One-Family Residence District limits buildings under Section 17.16.060 to a 'building height limit, two and one-half stories, but not to exceed thirty-five feet.' The AG-1 Agricultural/Upland District applies the same 35-foot/2.5-story limit to residential structures under Section 17.10.060, while allowing taller agricultural structures: grain silos and agricultural product storage and processing structures up to 60 feet, and non-commercial wind generators accessory to a permitted use up to 80 feet. General height exceptions in Section 17.08.040 allow architectural and mechanical features — 'silos, spires, chimneys, machinery, penthouses, scenery lofts, cupolas, water tanks' and similar — to be built to a height not more than twenty-five feet above the height limit, provided they are not used for sleeping, eating, or commercial purposes. These exceptions cover rooftop appurtenances, not additional living space. Accessory buildings have separate constraints: under Section 17.08.020, a garage or similar outbuilding not over fifteen feet in height at the ridge may be built against the side and rear line if it is at least seventy feet from any street. Maximum heights for other districts differ, so confirm the height limit for your parcel's specific zone. Variances from height limits may be sought under Chapter 17.72.
