Full Breakdown
Schedule 150.900.4 of the Dayton Zoning Code sets the window-sign standard for single-family residential and manufactured home districts: a window sign may cover no more than 20% of the window's glass area, cannot exceed three square feet, and only one window per dwelling may carry one. The same 20% cap applies to nonresidential uses in these districts, limited to one window per principal building instead. Window area is measured as the total glass area on the building frontage, with a single glass pane defined as any glass more than four inches from the next pane. Animated, flashing or electronic changeable-copy signs are barred under the same section.
Violations & Fines
Signs exceeding the coverage limit violate the Zoning Code and are subject to enforcement, correction or removal by the City's Zoning Administrator under Chapter 150.
