Summary
Jefferson County's sign code exempts window signs from its general permitting and design standards, but only up to a point: a sign posted inside a window counts as exempt only while it covers less than 40 percent of that window's glass area, per Zoning Section 1403.03.
1403.03 Exempt signs. The following signs are exempt from these regulations: a. Addresses. Address numerals used for the sole purpose of providing addresses; b. Directional. Directional signs of less than four (4) square feet in area with or without logos; c. Fuel pump logo. Corporate or brand logos attached to fuel pumps; d. Window signs. Signs posted inside of windows comprising less than 40% of the glass area; and, e. Construction signs. Temporary construction signs to be removed upon completion of construction.
Full Breakdown
03 of the Jefferson County Zoning Regulations lists the sign types exempt from the county's general sign standards, permit review, structural design and the sign classifications spelled out across Section 1403. Window signs make that exempt list, defined narrowly as signs posted inside of windows comprising less than 40% of the glass area. Staying under that 40 percent threshold means a business does not need a sign permit or setback review for what it displays behind its own glass, whether that is a static poster, a seasonal promotion, or a permanent decal.
Cross the 40 percent line, however, and the exemption falls away: the sign is no longer treated as an interior window display and instead must satisfy the same regulations that apply to any other sign in the district, including the general standards covering permitted sign types, prohibited sign categories, and the illumination and location rules that apply to permanent and temporary signage. The exemption sits alongside four other narrow carve-outs in the same subsection, address numerals, small directional signs under four square feet, fuel-pump logos, and temporary construction signs, all treated as outside the permitting system because of their limited size or duration rather than their content.
Because the 40 percent figure is measured against the glass area of the specific window the sign is posted in, not the storefront as a whole, a business with several display windows must keep each pane under the threshold to retain the exemption for all of them.
Violations & Fines
A window sign that covers 40 percent or more of the glass loses its exempt status and is treated as an unpermitted sign if it was installed without going through the standard sign-permit process the rest of Section 1403 requires. The Director of Development Services can require the display be reduced below the threshold, removed, or brought into compliance with the applicable permanent-sign standards, including setback and illumination rules, before enforcement is resolved.
