Summary
Washington County's sign rules do not reach signs painted, glued or otherwise attached directly to or visible through a window or glass door. Development Code Section 1.10(1) carves those signs out entirely, so no Sign Permit or Certificate of Compliance is required for window displays in the unincorporated county.
1.10 Signs
(1) Non-applicability. The regulations contained herein do not apply to signs painted, attached by adhesive or otherwise attached directly to or visible through windows and glass portions of doors.
Full Breakdown
10 of the Washington County Development Code opens with a non-applicability clause that removes window and glass-door signage from the sign regulations altogether. 10(2)), and a permit application must be accompanied by the established fee. 10(4), including the flashing-sign and electrified-sign restrictions that apply elsewhere in the code. This exemption applies only in the unincorporated area and townships the county regulates directly; incorporated cities within the county, such as Stillwater, Oakdale, Woodbury, Cottage Grove and Forest Lake, set their own sign rules and are not covered by this provision. Property owners inside those cities must check municipal code rather than the county Development Code.
Violations & Fines
Because window signs are outside the sign regulations, there is no permit-violation or fine exposure tied to Section 1.10(1) itself. A sign that is not truly painted on or visible through window glass, such as a freestanding yard sign mistakenly treated as exempt, remains subject to the county's normal permit and setback requirements, and the Zoning Administrator can order an unpermitted sign removed within thirty days of written notice under Section 1.10(4)(N).
