Summary
Window signs in Orange, whether painted on, attached to, or otherwise displayed within a window, cannot exceed 25% of that window's total area under Municipal Code Section 17.36.060(E). The limit applies per window and covers business, sale, and promotional signage placed at or behind the glass.
Window Signs. Any sign that is painted on, attached to, or otherwise displayed within windows shall not exceed 25% of each window's area.
Full Breakdown
060 sets the general rules that apply to every sign in the city's commercial and industrial districts, and subsection E addresses window signs directly: any sign painted on, attached to, or otherwise displayed within a window is capped at 25% of that individual window's area. Because the rule is measured window by window rather than by storefront or building elevation, a business with several display windows can dress each one up to the quarter-area limit without averaging across the whole facade. 120(C) allows them. Subsection F bars off-site commercial signs entirely: no commercial sign may advertise a business or generate income unless it is located on the same site as that enterprise, which rules out using a storefront window to advertise an unrelated business elsewhere.
Sign programs for larger developments in the C-TR, C-R, C-2, C-3, OTMU, NMU, and UMU zones may propose different criteria than this chapter's baseline limits, but only through Planning Commission or Community Development Director review of a formal sign program, not as a matter of right for an individual tenant's windows.
Violations & Fines
A window sign that covers more than 25% of the glass is a violation of Title 17 and, unless the City Attorney elects to prosecute it as an infraction, defaults to a misdemeanor under Section 1.08.010: up to a $1,000 fine, up to six months in County Jail, or both, with each day the oversized sign remains counted as a separate offense.
