Building permits in Green Bay

Most construction, renovation, and repair work in Green Bay, Brown County needs a building permit from Department of Community and Economic Development. Below are the office's contact details and online portal, plus step-by-step guides for the projects homeowners ask about most, from roofing and solar to fences, sheds, pools, and HVAC.

Wisconsin's Uniform Dwelling Code (SPS 320 to 325) is the statewide code for one- and two-family homes built on or after June 1, 1980 and their additions and alterations; it does not cover detached garages, sheds or other detached accessory buildings, and repairs are exempt. Every new home needs a Wisconsin uniform building permit, and each one carries a $30 state-issued UDC permit seal. Cities, villages and towns enforce the code, while a municipality of 2,500 or fewer people may instead ask the county to enforce it or leave enforcement to DSPS, which permits and inspects new homes only through state-contracted UDC inspection agencies. Whether an addition, alteration or smaller project in Green Bay needs a permit depends on the local ordinance, and the state plumbing and electrical codes apply to homes of any age. Confirm with the building inspection office that has jurisdiction over Green Bay before you start.

Permit FAQs for Green Bay

Do I need a building permit in Green Bay?
Most construction, renovation, and repair work in Green Bay needs a permit, including structural changes, electrical, plumbing, mechanical, roofing, and pools. Small cosmetic work is sometimes exempt. Every project must still meet the Wisconsin Uniform Dwelling Code (Wis. Admin. Code chs. SPS 320 to 325, a state-written code that is not based on the IRC), even when a permit is not required. Check your exact project with the free PermitRoadmap check.
Who issues building permits in Green Bay?
Department of Community and Economic Development issues permits for property inside Green Bay, Brown County. Your mailing city is not always the authority that permits your property, so confirm the jurisdiction before you apply. This page lists the department's phone, address, website, and online portal.
Can I pull my own permit as a homeowner in Green Bay?
In Green Bay, an owner who lives or will live in the home may pull the building permit without the state dwelling contractor credential (Wis. Stat. 101.654(1)(b)) but must sign the contractor liability statement required by Wis. Stat. 101.65(1r). An owner may also do electrical and plumbing work in a home the owner owns and occupies (Wis. Stat. 101.862(4)(a) and 145.06(4)(a)), unless a local ordinance requires a license.
Is there a dollar amount under which no permit is needed in Green Bay?
Not statewide. Wisconsin sets no statewide dollar threshold that waives a building permit, so whether small or cosmetic work needs a permit is decided locally. Confirm the exempt-work list and any value threshold with Department of Community and Economic Development before you start.
How much does a permit cost and how long does it take in Green Bay?
Fees and review times are set locally and change often, so confirm the current numbers with Department of Community and Economic Development or its online portal. Fees are usually based on the value of the work or a fixed schedule, and simple residential permits are frequently reviewed faster than new construction.
