Full Breakdown

06(O), part of the Standards for Special Category Signs, treats window signs as their own category with two distinct tracks. Paragraph 5 sets the permanent-sign ceiling: permanent window signs cannot occupy more than twenty percent of the total window area on a given storefront. Paragraph 6 layers on placement and format rules for those permanent signs, restricting them to windows on the ground level and second story of a building frontage, and requiring the signage itself to consist of individual letters, logos, or symbols applied directly to the glass, though neon signs with transparent backgrounds may be hung just inside the window line.

Paragraph 7 covers temporary window signs separately and much more tightly: they may be displayed for a maximum of ten days at a time and only in ground-floor windows, unlike the permanent-sign track, which reaches the second story. 06(A)(2), which allows incidental window signing at car lots up to twenty-five percent of window area without a sign permit at all. 02.

Violations & Fines

A window sign that exceeds the twenty percent coverage cap, hangs past the ten-day temporary display window, or sits above the second story without a sign permit is an unpermitted sign under Chapter 16.509. Enforcement runs through the city's general penalty section, Section 1.12.010: a first violation is an infraction carrying a fine of $100 to $500, escalating to a misdemeanor with a fine of $500 to $1,000 or up to six months in jail for repeat or more serious violations, and each day the oversized or expired signage remains posted is its own violation.

Frequently Asked Questions

How much of my storefront window can I cover with signs in Vallejo?
Twenty percent, if the signage is permanent. Municipal Code Section 16.509.06(O)(5) caps permanent window signs at twenty percent of the total window area, and paragraph (6) further limits where those signs can go: only ground-level and second-story windows on the building frontage.
How long can a temporary sale sign stay in a Vallejo storefront window?
Ten days at a time. Section 16.509.06(O)(7) allows temporary window signs to be displayed inside a window for a maximum of ten days, and it confines them to ground-floor windows only, unlike permanent window signs, which can also reach the second story.
Can I put a neon sign in my Vallejo shop window?
Yes, with a placement limit. Section 16.509.06(O)(6)(b) allows neon signs with transparent backgrounds to be hung inside the window glass line as part of the permanent window sign allowance, provided the combined permanent window signage still stays within the twenty percent coverage cap.
