Frequently Asked Questions

How much does a deck permit cost in Milwaukee?

Milwaukee deck permits typically cost $150 to $350, depending on the deck's size and complexity. You need to submit a site plan showing the deck location relative to property lines and a construction drawing showing footing sizes, post-to-beam connections, joist sizing, ledger attachment, and railing details. The permit fee includes plan review and inspections.

Do ground-level decks need a permit in Wisconsin?

Requirements vary by municipality. Ground-level decks (less than 30 inches above grade) are exempt from the UDC statewide requirement, but many cities — including Milwaukee and Madison — require permits for all attached decks regardless of height. Ground-level patios made from pavers or poured concrete at grade are generally exempt. Always check your local code.

What inspections are included in a deck permit?

A standard deck permit in Wisconsin includes a footing inspection (before pouring concrete), a framing/structural inspection (after the frame is up but before decking is installed), and a final inspection (after all work is complete including railings and stairs). Some municipalities combine the framing and final inspections for simple decks.
