Frequently Asked Questions
Do I need a permit to put up a business sign in Wisconsin?
Yes. Most Wisconsin municipalities require a sign permit for any permanent business sign, including wall signs, ground/monument signs, projecting signs, and awning signs. Temporary signs (banners, sandwich boards) may also require permits or be regulated under separate temporary sign ordinances. Sign regulations cover size, height, location, illumination, and materials.
What are the typical sign size limits in Wisconsin?
Sign size limits are set by each municipality's zoning code and vary by district and sign type. In commercial zones, wall signs are typically limited to 10–15% of the building facade area. Ground signs are often limited to 32–100 square feet depending on the zoning district and road frontage. Residential zone sign regulations are much more restrictive. Always check your local sign ordinance for exact limits.
Do I need an electrical permit for an illuminated sign?
Yes. Any sign with electrical illumination — whether internally lit, externally lit, or using LED/neon — requires an electrical permit in addition to the sign permit. This includes channel letter signs, cabinet signs, and digital displays. The electrical work must be performed by a licensed electrician in most municipalities.
