One thing Milwaukee does not make you permit
Worth knowing before you call anyone. Most jurisdictions we cover require all of these.
- Patio Permit
No DNS permit is needed for an at-grade patio on private property, but any work touching the public sidewalk or the curb-cut driveway approach needs separate Department of Public Works approvals and permits, and a raised deck or a pool deck is a building permit rather than a patio
