Summary
Hayward caps window signs at 25 percent of a window's total area citywide. The Municipal Code's sign definitions section describes a window sign as anything attached to, suspended behind, or placed within 24 inches of a glass window or door and intended to be viewed from outside, then sets the coverage limit right in that definition.
Window Sign. A sign attached to, suspended behind, and/or placed less than twenty-four (24) inches inside a glass window or door of a building, or painted upon the window or glass door of a building, and which is intended for viewing from the exterior of such building. This excludes seasonal displays. Window signs are allowed to cover a maximum of twenty-five (25) percent of the total window area in any zoning district.

Full Breakdown
800 of the Hayward Municipal Code, in the sign regulations article's definitions section, defines 'Window Sign' as 'a sign attached to, suspended behind, and/or placed less than twenty-four (24) inches inside a glass window or door of a building, or painted upon the window or glass door of a building, and which is intended for viewing from the exterior of such building,' excluding seasonal displays. ' Because the cap is written as applying 'in any zoning district,' it reaches every storefront and building citywide rather than one commercial subarea.
Hayward's downtown-specific design standards for the CC-C, CC-R, and CC-P subdistricts add further detail on top of this citywide cap: permanent window signs there may include graphics painted on glass, vinyl lettering, or small neon window signs, should be light in color, and do not count toward the separate allowable wall and projecting sign area for the storefront. A sign installed within a window that exceeds a quarter of the glass area is a Municipal Code violation regardless of what the sign says or how it is lit.
Illegal signs on private property, including oversized window signs, are subject to removal by the Development Services Director under the sign enforcement provisions of the code.
Violations & Fines
A window sign covering more than 25 percent of the window area violates Section 10-7.800 and can be removed by the Development Services Director under Section 10-7.711, Enforcement of Signs on Private Property, following the abatement procedures set out in Chapter 5, Article 7 of the Municipal Code. The violation is also chargeable as a general infraction under Section 1-3.00, with each day the oversized sign remains treated as a separate offense.
