Summary
A shop window in the Town of Amherst can't be more than 20 percent covered by signs or posters. Amherst Code § 7-8-3B(9) treats a temporary window sign as exempt from a building permit, but only up to that one-fifth coverage ceiling, measured pane by pane rather than across the whole storefront.
§ 7-8-3B, Item 9. WINDOW SIGN: "A temporary, non-structural sign located in the interior of a window or door or any other sign inside the building containing a message legible from the public right-of-way or adjacent property clearly intended for public recognition outside the building." Standards: "No window sign or advertising poster shall occupy more than 20 percent of the area of an individual window pane."
Full Breakdown
Window signs fall under § 7-8-3B, the Zoning Ordinance's list of "Signs Not Requiring a Permit," as item 9. " That sweeps in paper posters, painted lettering and interior signage placed to be read from the sidewalk or parking lot, not just professionally printed clings. " Because the limit runs pane by pane, a storefront with several separate panes can dress each one up to the 20% line, but a single oversized poster covering more than a fifth of one pane is out of compliance even if the rest of the glass is empty.
Like the other permit-exempt sign types in § 7-8-3B, a window sign is not reviewed by the Building Department before installation, but the Commissioner of Building can still act against a sign that exceeds the coverage cap.
Violations & Fines
A window display that exceeds the 20 percent coverage limit is treated as a noncompliant sign under § 8-10-7 and § 8-10-8, and the Commissioner of Building can direct the owner, occupant or user to bring it into compliance or remove the excess signage. Ignoring that order is a Zoning Ordinance violation under § 8-16-1, fined up to $350 for a first offense and $700 to $1,000 for a third or later offense within five years, with each week counted as a separate violation.
