Summary
Pomona limits window signs to 50% coverage of any window panel under Zoning and Development Code Sec. 630.F.2.g, whether the signs are temporary, permanent, or a mix of both. Window signs are restricted to ground-floor windows, capped at 2 per lot (or per 30 feet of building frontage, whichever is greater), and combined with a business's total building sign area allowance.
g. Window Sign 1. DEFINITION A building sign which is painted on, applied to, attached to, or projected upon the glass area of a building facade, including doors, or located within 12 inches of the interior of a window. 2. GENERAL STANDARDS i. Any window sign must only be displayed in ground floor windows. ii. No combination of temporary and permanent window signs may cover more than 50% of any window panel. 3. NUMBER OF SIGNS Maximum of 2 per lot or per 30' of building frontage, whichever is greater. 4. TOTAL SIGN AREA Combined area of all building signs (max) 1.5 SF per linear foot of building frontage or at least 32 SF, whichever is greater.
Full Breakdown
Sec. g defines a window sign broadly: anything painted on, applied to, attached to, or projected upon the glass area of a building facade, including doors, plus any sign located within 12 inches of the interior of a window counts even if it's not physically on the glass. That sweeps in paper flyers taped inside a storefront window as well as vinyl decals on the glass itself. Two general standards apply regardless of sign type. First, window signs can only go in ground-floor windows, so upper-story glass can't carry signage.
Second, no combination of temporary and permanent window signs may cover more than 50% of any window panel, meaning a business can't stack a permanent decal and a temporary sale sign on the same pane past the halfway mark. Numerically, a lot gets a maximum of 2 window signs, or 1 per 30 feet of building frontage, whichever produces the larger number for wider storefronts. 5 square feet per linear foot of building frontage, or 32 square feet minimum, whichever is greater, shared with wall, projecting, roof and other permanent building signs.
Individual window signs are further capped by background type: 10 square feet for a sign with an opaque background, no separate cap for a sign with no background, and just 4 square feet for an internally illuminated or exposed neon window sign.
Violations & Fines
A window display that blows past the 50% coverage cap or exceeds the per-lot sign count is enforced the same way as any other sign violation: Sec. 630.D.6.a requires nonconforming or excess signage to be removed and any residue cleaned up, and the property owner can also be cited under the City Code's general penalty, Sec. 1-7, as an infraction (up to $500 for a repeat violation within a year) or a misdemeanor carrying up to a $1,000 fine and six months in jail.
