Green Bay sign permit requirements

What the Green Bay sign code and sign ordinance allow, summarised from Chapter 30 - SIGNS. Every figure below shows the ordinance's own wording, so you can check it rather than take our word for it.

Check before you build. This is an informational summary, not legal advice, and sign rules change. Confirm with Green Bay's planning department before ordering or installing a sign — most codes also vary by zoning district.

Permit (sign authorization/site plan) required for all signs except exempt signs listed in Sec. 30-6 (e.g., nameplates ≤1 sq ft, directional, construction, political, temporary sales signs, etc.)

“All signs, except exempt signs as listed in Section 30-6 , shall be required to submit a site plan, sign details, hold harmless agreement, if necessary, and other information, as regulated in Chapter 44 , Article XIX, to the office of the Zoning Administrator, or their designee, for review of compliance with all applicable codes.”
