Lake County, CA Home Business: Zoning & Home Occupation Permits (2026)

Sec. 3(j) sets the baseline conditions a home occupation must meet countywide. The business must be strictly secondary and subordinate to the principal residential use, and it cannot change or detrimentally affect the residential, agricultural or rural character of the dwelling, premises or neighborhood. Where the home occupation is conducted depends on zoning: in the R1 and R2 districts, and on SR lots under one acre, the business must stay inside the dwelling or an attached garage, with no work in a detached garage, storage shed or other accessory building.

In other districts where home occupations are allowed, the business can occupy the dwelling or an accessory structure that is incidental in size to the principal dwelling. Structural alterations made to accommodate the home occupation need Planning Director review and approval for consistency with neighborhood character and building architecture. Staffing is likewise tied to zoning: in R1, R2 and small SR lots, only the dwelling's own occupants may work in the business, with no on-site employees permitted at all, while in other zoning districts on-site staff is capped at one employee per two acres of parcel area and a maximum of five employees total.

Commercial pickup and delivery to the property is limited to ten trips per week, and the business is barred from creating radio or television interference or noise audible at the property line. No materials or supplies connected to the home occupation may be stored outdoors.
