r. Temporary window signs constructed of paper, cloth or similar expendable material, provided: 1. The total area of such signs shall not exceed 25 percent of the window area. 2. Such signs shall be affixed only to the interior window surface for a short period of time to promote a particular sale of produce or merchandise.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-141: Administrative: Current through Ord. No. 11007 (N.S.), effective 7-10-26 | Regulatory: Current through Ord. No. 11008 (N.S.), effective 7-24-26).
Full Breakdown
Under the county's Zoning Ordinance, unincorporated San Diego County exempts temporary window signs from a sign permit entirely, but only if they are made of paper, cloth, or similar expendable material, cover no more than 25 percent of the window area, and stay affixed to the interior glass for a short period to promote a sale of produce or merchandise. Anything more permanent does not get this pass: the ordinance's definitions treat a permanent window sign as a wall sign, pulling it into the county's full wall-sign area, height, and permit rules.
Violations & Fines
Exceeding the 25 percent window-area cap, using rigid or permanent signage instead of paper or cloth, or leaving a promotional sign up beyond a short sale period turns it into an unpermitted sign subject to the county's nonconforming-sign abatement process.
