The permitting process is managed by Milwaukee DNS and typically requires detailed plans, proof of licensing, and insurance documentation. Milwaukee's plumbing market offers solid opportunities across residential and commercial sectors, with typical project values ranging from simple fixture work to major renovations and new construction.
