Sign Regulations in Green Bay, WI

If you live in Green Bay or are thinking about moving there, sign regulations are one of those things you probably won't think about until they affect you directly. Green Bay has 3 specific rules on the books covering different aspects of sign regulations, and some of them might surprise you.

Garage Sale Signs

Green Bay allows two temporary sale signs per property, up to eight square feet each, set back five feet from property lines, but they must come down within three days of the sale ending.

Key details: Max signs: 2 per property. Max size: 8 sq ft each. Setback: 5 ft from property lines. Duration: Up to 3 days.

A garage-sale sign that's oversized, over the two-sign limit, or left up past the sale is an unlawful sign, removable by the Zoning Administrator after notice, with costs billed to the owner.

Window Signs

In Green Bay's Commercial districts (C1, C2, C3), window signs are capped at one per window, not exceeding 50 percent of the window's area, under Municipal Code § 30-36 and Table 30-2. Window signs sit outside the wall-and-awning sign area total, but they still need sign authorization unless they qualify as an exempt sign under § 30-6.

Key details: Window sign limit: 1 per window, max 50% of window area. Applies in: C1, C2, C3 Commercial districts. Counted separately from: Wall and awning sign area total. Illumination: Allowed; flashing/rotating not allowed. Noncompliance notice period: 30 days to correct.

A sign found unsafe, insecure, or erected in violation of Chapter 30 draws a written notice from the Zoning Administrator under § 30-5(7); the owner has 30 days to bring it into compliance, after which the Zoning Administrator may remove or alter the sign and bill the property owner for the cost. The Zoning Administrator will also refuse a new sign permit to anyone whose proposed sign would pose an immediate peril to persons or property.

Digital Billboards

Green Bay only allows digital billboards as a conditional use, with message transitions under a second, an eight-second minimum display time, automatic dimming, and a mitigation requirement tied to removing older billboards.

Key details: Permit: Conditional use required. Brightness cap: 0.3 fc over ambient. Timing: ≤1 sec transition, ≥8 sec hold. Mitigation: 5 pts/face via billboard removal.

A malfunctioning or glaring digital billboard, or one interfering with a traffic signal, must be shut off immediately on the Public Works Director's order and can't restart without City approval, per Sec. 30-63(4).

This is one of the stricter rules in Green Bay's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

The Bottom Line

Green Bay's sign regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Green Bay is broadly strict or permissive.
