Summary
A temporary window sign made of paper, cloth or similar expendable material is exempt from Glenn County's sign permit rules, but the total area of those signs cannot cover more than twenty-five percent of the window under Code Section 15.62.030. Go over that quarter-window limit and the display no longer qualifies for the exemption.
Window Signs. Temporary window signs constructed of paper, cloth or similar expendable material; provided, the total area of such signs shall not exceed twenty-five percent of the window area.
Full Breakdown
030 lists the categories of signs exempt from the county's general sign permit requirements and from the site's total permitted sign-area calculation. 060 instead. The same exemption list covers other common small-business signage that a Glenn County shop owner is likely to use alongside window signs: two agricultural product signs up to thirty-two square feet total, two construction signs up to thirty-two square feet removed within fourteen days of finishing work, temporary real estate signs up to four square feet on residential lots or thirty-two square feet on commercial lots, and temporary sale or grand-opening banners up to one hundred square feet posted no more than thirty days before the event and removed within seven days after.
060. A window sign built of rigid, permanent material such as vinyl-backed acrylic, or one that covers more than a quarter of the glass, loses the exemption and must be sized and permitted under the standard commercial sign-area formula instead.
Violations & Fines
A temporary window display of paper or cloth that exceeds twenty-five percent of the window area no longer qualifies as exempt under Section 15.62.030 and must instead comply with the chapter's regular permit and area limits for appurtenant signs under Section 15.62.060, including the property owner consent filing required by Section 15.62.020. Operating an oversized or unpermitted window sign is enforced as a code violation: an infraction on the first offense, rising to a misdemeanor with up to a $5,000 fine or a year in jail on a third violation within 12 months under Sections 1.12.010 and 1.13.010.
