Full Breakdown
Table 107-113 sets the maximum sign area allowed for a home occupation in unincorporated Linn County, scaling from 8 square feet on parcels of one acre or less up to 32 square feet on parcels of ten acres or more. A footnote to the table caps sign height at five feet and bars illumination outright: no lit, backlit, or spotlighted home-business signage anywhere outside the county's incorporated cities. The sign must be tied to an approved home occupation; there's no separate at-large sign permit for a home business.
Violations & Fines
A home-business sign that exceeds the size or five-foot height cap, or that is illuminated, is a sign-code violation the zoning administrator can order removed or brought into compliance.
