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

16 sets the maximum building height for the R1 Single-Family Residential district: 35 feet for the principal structure and 20 feet for any accessory structure, a figure carried forward from Ordinance No. 1749, adopted July 7, 1988. 14, which drops from 35 percent to 30 percent once a home goes to two stories. Together these standards keep taller homes both further from the rear line and smaller in footprint, rather than regulating height in isolation. 15(d). 5. A homeowner who wants to build taller, such as a three-story home or a tall detached shop, needs relief through the variance process in Article 52, which requires demonstrating that the property's size, shape or topography creates a hardship not shared by other R1 lots and that the variance will not grant a special privilege inconsistent with other properties in the zone. Height measured for structures like communications antennae is instead governed separately under Article 71.
