Full Breakdown
The Sign Code caps window signage citywide: no instance may window signs cover more than 20 percent of a storefront's window space, and every window sign must be affixed to the interior of the glass rather than posted outside. Window signs are one of the few sign types exempt from the City's sign-permit requirement, but they still have to comply with this coverage cap and every other applicable provision of the Sign Code. Code Enforcement in the Building Inspection Division handles violations, and oversized or improperly mounted window displays can be ordered removed.
Violations & Fines
Exceeding the 20% window-coverage cap, or affixing a sign to the exterior of the glass instead of the interior, puts the display out of compliance and subject to Code Enforcement removal orders.
