Permanent window signs must not cover more than 25 percent of the total window surface... Temporary window signs must not cover more than 25 percent of the total window surface, except as follows: Temporary window signs on vacant non-residential tenant spaces may occupy up to 95 percent of the total window surface for no longer than nine months in any calendar year.
Full Breakdown
Sec. 25.10.3.6 sets the same 25 percent window-surface cap for both permanent and temporary window signs, with a carve-out letting temporary signs on vacant non-residential tenant spaces cover up to 95 percent of the window for up to nine months per calendar year. Permanent and temporary window signs alike are prohibited on single-unit detached dwellings, townhouses, and multiplexes, and neither may sit within four inches of the window frame. Temporary window signs may run for up to one year and can be mounted inside or outside the glass; permanent signs must be mounted on the interior side only, though they may be illuminated.
Violations & Fines
A window sign exceeding the 25 percent cap (outside the vacant-storefront exception), placed on a prohibited residential building type, or displayed past its one-year temporary limit is a Zoning Ordinance sign violation subject to City enforcement.
