Summary
In unincorporated Los Angeles County, temporary window signs on business storefronts can't cover more than 25 percent of any single window or connected window run along the same frontage.
Each business establishment shall be permitted temporary window signs, provided that such signs do not exceed 25 percent of the area of any single window or of adjoining windows on the same frontage. This provision is not intended to restrict signs utilized as part of a window display of merchandise when such signs are incorporated within such display and located not less than one foot from such windows.
Full Breakdown
Los Angeles County Code § 22.114.150 caps temporary window signs, paper, vinyl, paint, or similar lightweight material affixed to or within three feet of a window's interior, at 25 percent of a single window's area, or of adjoining windows sharing the same street frontage. The limit applies only in the unincorporated county, where County Planning enforces Title 22's sign standards; the 87 incorporated cities, including the City of Los Angeles, set their own window-sign rules. Signs built into an in-window merchandise display sitting at least one foot back from the glass are exempt from the coverage cap.
Violations & Fines
Exceeding the 25 percent cap is a zoning code violation; County Planning can issue a correction notice, and unresolved violations escalate to citations under Title 22's enforcement chapter.
