Temecula, CA Sign Regulations: Window Signs (2026)

600, which governs temporary business advertising signs in commercial, professional office and industrial districts. The section identifies three types of promotional signs a business may use: attached, detached and window signs, and it specifically bars a business from running attached, detached and promotional window signs that require a permit in combination during the same quarter. 600(C)(3) sets two hard limits: signage placed on non-door window surfaces cannot cover more than seventy-five percent of the non-door window area, and the display cannot run longer than a ninety-day period.

These promotional window signs sit within the broader temporary-signage framework the city adopted to curb visual clutter and protect the aesthetic quality of its commercial and service districts, as the section's own findings state. 050(P) are expressly excluded from counting toward a business's permissible window sign area. Because the ninety-day promotional window sign allowance runs independent of the other promotional sign types, a business rotating window displays for more than ninety consecutive days, or covering more than three-quarters of its window glass with temporary advertising, has moved outside the exempt promotional category.
