St. Johns County, FL Sign Regulations: Window Signs (2026)

Sec. 06 Additional Permanent Signs in All Zoning Districts sets out a short list of signs allowed everywhere in unincorporated St. Johns County without counting against a site's overall sign budget, and Window Signs are one of them. The code requires a Window Sign to be legible only from the Premises on which it is located or from inside the Business, bars it from being used for Commercial Messages, and limits it to no more than 25 percent of the area of any one window or door.

No Sign Permit is required for a Window Sign, in contrast to most On-Premise Permanent Signs, which need a permit and fee under Sec. 08 before installation. The same Sec. 06 also authorizes Flags (capped at three flying at once, with drop length limited to 20 percent of the pole or flag height) and small ingress/egress or directional signs (3 square feet, 3 feet tall) without a permit, showing the county treats window signage as a minor, self-limiting category rather than one requiring administrative review.

Because there is no permit step, compliance with the 25 percent cap is checked reactively, typically after a complaint or a code inspection of the storefront.
