Do I need a permit for a concrete patio?
Ground-level patios often do not require a building permit, but may need a zoning permit to verify setback compliance. Elevated concrete work or structural slabs require a building permit.
Do I need a permit for a sidewalk?
Private sidewalks on your property may not require a building permit in many municipalities. Sidewalks in the public right-of-way always require permits.
What about impervious surface limits?
Many Wisconsin municipalities limit total impervious surface (concrete, asphalt, buildings) to 40-60% of lot area. Adding significant concrete may trigger stormwater management requirements.
