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.

These county ordinances apply to unincorporated areas of Washington County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

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).

Frequently Asked Questions

Do I need a permit for a sign in my store window in Washington County?
No. Development Code Section 1.10(1) states the sign regulations do not apply to signs painted, attached by adhesive, or otherwise attached directly to or visible through windows and glass portions of doors, so no Sign Permit or Certificate of Compliance is needed for that display.
Is there a size cap on window signs in the unincorporated county?
The Development Code does not set one. Section 1.10(1) removes window and glass-door signs from the sign regulations entirely, so the size and area limits that apply to yard signs, development signs and other permitted signage under Section 1.10 do not extend to window displays.
Does this exemption apply inside Stillwater or Woodbury?
No. Section 1.10 governs only the unincorporated area and townships that Washington County regulates directly; incorporated cities like Stillwater, Oakdale, Woodbury, Cottage Grove and Forest Lake adopt and enforce their own separate sign ordinances.
