Repair or replacement of decking on porches, decks and balconies requires a permit. Check with DNS for specific exemptions for minor work.
If your deck does NOT meet all exemption criteria, you must obtain a permit before construction. Building without a required permit can result in fines, stop-work orders, and required demolition.
Review the exemption criteria above. If your deck exceeds any threshold, a permit is required.
You'll need a site plan, deck dimensions, framing details, and footing specifications. Check Milwaukee's specific documentation requirements.
Apply through Milwaukee DNS Permits . Pay the permit fee at submission.
