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

060(C) sets the standard for the Limited Residential (R-L) district, the county's general-purpose residential zone. 030, the code's height-limit-exceptions section. Accessory buildings follow a graduated scale keyed to distance from the property line rather than a single flat number: an accessory building closer than fifty feet from any property line is capped at twenty feet; one set back at least fifty feet but less than seventy feet may reach twenty-five feet; one set back at least seventy feet but less than ninety feet may reach thirty feet; and only once an accessory building sits at least ninety feet from every property line can it reach the same thirty-five-foot cap that applies to the main building.

The scale links height to distance, so a taller shed, barn, garage or workshop must also sit farther from neighboring lots. Because this height table lives inside the R-L district's own site development standards, it applies only to parcels zoned R-L; the Limited Agriculture (A-1), Rural Residential (R-R) and other districts each carry a separate structural-height provision in their own site development standards section, so a property owner should confirm the parcel's zoning district before assuming the thirty-five-foot main-building figure applies.
