Summary
A home occupation sign in unincorporated Washington County cannot exceed nine square feet, and Development Code Section 1.10(7) only allows one at all if the home occupation fronts a county road and is permitted under Section 2.6 of Chapter Two.
(7) Home Occupation. A sign no greater than nine (9) square feet in size is permitted for any home occupation that is along a County road and permitted under Chapter Two, Section 2.6 of the Development Code.
Full Breakdown
10(2)(B), so a compliant home occupation sign of that size does not need a separate Sign Permit. 6, which requires the business be clearly incidental and subordinate to the residential or agricultural use of the property, be carried on solely within the main dwelling or accessory buildings, and be operated by the resident occupant. 10. Because the sign allowance is tied to road frontage on a County road, a home occupation that fronts only a local, township or private road does not automatically get this signage right under the county code. The provision applies solely in the unincorporated area and townships; incorporated cities such as Stillwater and Woodbury set their own home-business sign limits.
Violations & Fines
A home occupation sign larger than nine square feet, or one erected for a home occupation that fronts something other than a County road, falls outside Section 1.10(7)'s allowance and is treated as an unpermitted sign; the Zoning Administrator can order it removed within thirty days of written notice under Section 1.10(4)(N), and the underlying home occupation itself can lose its Certificate of Compliance for noncompliance with Section 2.6's performance standards.
