Full Breakdown
Manteca Municipal Code § 17.54.040(B)(2) exempts permanent window signs, hung inside the glass or stenciled on the inside or outside of a window, from the City's Sign Permit requirement. The exemption caps coverage at four square feet per street frontage and bars illumination; the code notes such signs are encouraged for business identification, hours of operation, and address information. A larger or lit window display falls outside the exemption and needs a Sign Permit under Chapter 17.54, and any exception to the limit requires a Variance under § 17.10.120.
Violations & Fines
A window sign over four square feet per frontage, or an illuminated one, loses its permit exemption; operating without the required Sign Permit is a zoning violation Code Enforcement can act on.
