Summary
Placer County exempts temporary window signs from a sign permit, but only if the total window signage covers no more than 25% of the window area and stays up no longer than 30 days within any 60-day period, under County Code § 17.54.170(C)(2)(p).
Window Signs. Temporary window signs, either painted with water-soluble paint, or constructed of paper, cloth or similar expendable material, provided the total area of such signs is not more than 25% of the window area, and provided that such signs are in place no longer than 30 days in any 60 day period.
Full Breakdown
170(C)(2)(p) treats temporary window signs as an exempt sign category, meaning they do not require a sign permit, so long as they meet three conditions: the sign must be painted with water-soluble paint or made of paper, cloth, or similarly expendable material; the total area of window signage on a given window may not exceed 25% of that window's area; and the signage may be displayed for no more than 30 days within any 60-day period. 170(C)(2), which also exempts building directory signs (10 square feet, 8 feet tall maximum), construction signs (32 square feet combined), fuel dispenser signs (5 square feet), and holiday decorations (60-day display cap, no height limit).
Exempt signs must still comply with a 6-foot height cap unless another exemption specifies otherwise, and still require a building or electrical permit if Chapter 15 of the county code (Construction Requirements) applies. 180, including sign-area and permit requirements for the applicable commercial or industrial zone district.
Violations & Fines
A window sign that exceeds 25% window coverage, uses non-expendable material, or stays up beyond the 30-in-60-day window is no longer exempt and requires a sign permit under § 17.54.170(B); placing it without one is a violation enforceable under the sign ordinance's general provisions, and non-conforming signage can be ordered removed or brought into compliance by the planning department.
