Summary
Dublin, California limits window signs to 25 percent of the contiguous window area they're displayed on. The city treats window signs as exempt from a sign permit, but every other Chapter 8.84 sign standard, including prohibited content, still applies to them.
Window Signs shall not exceed twenty-five (25) percent of the contiguous window area from which they are viewed.
Official source re-checked September 8, 2026: no newer edition of the code had been published (publisher’s edition: current through Ordinance 2-26, passed March 3, 2026).
Full Breakdown
" That exemption sits alongside other permit-free sign types in the same section, such as A-Frame Signs (one per business, six square feet per side, four feet tall, removed daily), Real Estate Signs (sixteen square feet per side, two per parcel), and Temporary Non-Commercial Signs (sixty days maximum, sixteen square feet per sign, eighty square feet aggregate per lot). 150, which bars blinking or flashing lights, obscene content, and oversized balloons displayed above ten feet in commercial or industrial zones. The 25 percent cap was most recently reaffirmed by Revised Ordinance 10-25, adopted December 2025, following earlier amendments in Ordinance 4-23 (September 2023), Ordinance 2-21 (April 2021), and Ordinance 7-12 (May 2012), showing the city has kept revisiting sign coverage limits as its retail corridors along Dublin Boulevard and San Ramon Road have grown.
Violations & Fines
Because window signs fall under Title 8, an oversized window sign is enforced as an infraction under Section 8.144.060, punishable by a fine of up to $100 for a first offense, up to $200 for a second within one year, and up to $500 for a third; a fourth violation within that year can be charged as a misdemeanor under Section 8.144.070.
