Insights
Wisconsin's Uniform Dwelling Code (UDC) establishes a minimum of 6 inspection stages for new residential construction. Larger municipalities add inspections beyond this minimum based on local ordinances — Milwaukee requires double the state minimum at 12 stages.
For deck projects, most municipalities require only a footing inspection and final inspection (2 stages). Madison, Milwaukee, and Brookfield add a framing/ledger board inspection (3 stages). Waukesha also requires a post-hole depth verification before concrete (4 stages).
Kitchen and bath remodels involving plumbing, electrical, and structural modifications typically require 3-7 inspections depending on scope. A simple fixture replacement may need only a final plumbing inspection, while a full gut remodel with moved walls requires rough and final inspections for each trade involved.
Smaller municipalities (Menasha, Marshfield, Superior) use a single-inspector model where one person handles all trade inspections, often allowing combined inspection visits that reduce contractor scheduling burden.
Failed inspections require re-inspection. Most municipalities include one free re-inspection; subsequent re-inspections cost $50-$150 each. Milwaukee charges $75 per re-inspection after the first failure.
Methodology
Inspection counts represent the total number of required inspection stages for a standard new single-family home construction project including all trade work (electrical, plumbing, HVAC). Data sourced from municipal building department inspection checklists and UDC enforcement records. Counts do not include re-inspections or specialty inspections for items like swimming pools, elevators, or fire suppression systems. Deck and remodel inspection counts are discussed in insights.
