Green Bay, Wisconsin Building Permit Guide

Green Bay once required its own HVAC license and then repealed it — a door most cities keep open, documented closing. What remains is precise: a three-outlet electrical trigger, witnessed plumbing tests, and doubled fees when work starts unpermitted.

Short form and long formAll commercial on the long form

Green Bay's local rules are specific enough to quote. The city used to license HVAC contractors and now expressly does not; an electrical permit is triggered by adding more than three outlets even when no building permit applies; and since October 2021 every sanitary and drain-waste-vent installation is pressure-tested in front of the plumbing inspector.

The Inspection Division, within Community and Economic Development at 100 North Jefferson Street, issues residential and commercial permits, reviews site plans, and runs a two-form intake: a short application for driveways, sheds, fences and patios, and a long application for everything else — including all commercial work.

This guide covers the City of Green Bay. The separate Town of Green Bay, plus De Pere, Ashwaubenon, Howard, Bellevue and Allouez, permit on their own; several use private inspection agencies, so the parcel decides the counter.

📜

The HVAC door closed here. The city's own commercial permits page states that Green Bay formerly required HVAC contractors to obtain city licensing and that the requirement is no longer in effect — state registration still applies. Where Milwaukee stacked five city licenses on top of the state's, Green Bay went the other way and wrote it down.

What requires a building permit in Green Bay?

Typically permit required

  • New buildings, additions and remodels on both tracks
  • Electrical work adding more than three outlets — receptacles, lights or switches — even with no building permit in play
  • All heating work, under HVAC permits
  • Sanitary sewers, storm sewers, turf watering systems and water heater replacement, under plumbing permits
  • Work on designated historic properties, which needs a Certificate of Appropriateness through the Landmarks Commission before the permit

Often exempt

  • Minor electrical repairs below the three-outlet trigger
  • Ordinary maintenance and finishes that do not alter structure or systems
  • Buildings used for farming — exempt from the state commercial building code under Wis. Stat. 101.05(5), with farming defined by DSPS rule; a produce stand stays exempt only while at least 90 percent of what it sells was grown or produced on the farm
  • Primitive rural hunting cabins — carved out of municipal jurisdiction by Wis. Stat. 101.65(1g)
  • Bed-and-breakfast establishments as defined by statute — outside the commercial building code under Wis. Stat. 101.05(2), though a third floor in use or a new addition must meet the Uniform Dwelling Code

What is actually local, and what is not

Green Bay cannot vary the state codes, and it removed the one licensing overlay it had. Its local layer is procedural: the two-form intake, the three-outlet trigger, the witnessed plumbing tests under SPS 382.21, Landmarks review on the third Wednesday of the month, and a doubled fee on unpermitted work.

Wisconsin's Uniform Dwelling Code covers one- and two-family homes. Its Commercial Building Code covers public buildings, workplaces and buildings of three or more units. Local ordinances must conform to both. Wisconsin rules

Who handles permitting in Green Bay?

The Inspection Division issues permits and inspects both tracks. Green Bay holds second-class-city delegation covering commercial buildings of all sizes, and contracts the plan-review function to E-Plan Exam, the private reviewer named on the state's delegated-authority roster.

In 2025, building permits issued in Green Bay authorized 283 new privately owned housing units, 56 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Houses run on the Uniform Dwelling Code. To pull a permit on a one- or two-family dwelling a contracting business must hold the state Dwelling Contractor certification and employ a Dwelling Contractor Qualifier — the city page states it verifies both before issuance. An owner who occupies an existing single-family home may permit their own work; duplexes and condominiums are expressly not single-family for this purpose, and rental property work must be done by licensed contractors.

How Wisconsin contractor licensing works

Wisconsin certifies dwelling contractors and licenses electricians and plumbers at state level (see Wisconsin rules). Green Bay rescinded its former municipal HVAC license, leaving state registration as the only HVAC credential, and adds no other city trade license.

Commercial permits

All commercial submittals use the long-form application and route through the city's delegation, with E-Plan Exam performing the review at every size. Plan approval precedes the permit; sealed drawings and a supervising professional attach at 50,000 cubic feet.

Mechanical work, and where the state reviews directly

Commercial plans above set sizes go to the state for review first (see Wisconsin rules). Since October 1, 2021 the city enforces SPS 382.21 as written: sanitary sewer and interior drain, waste and vent installations are tested and witnessed by the plumbing inspector, with the responsible plumber required to notify the Division ahead of the test.

Green Bay permit costs and fees

Fees are modest and the enforcement posture is not. On the 2026 schedule, one- and two-family plumbing bills at $7 per fixture ($8 on multi-family and commercial work), with water service and sewer connections at $50 each; the serious number is what happens without a permit.

Green Bay fee reference points
ItemFee or rule
Plumbing fixtures$7 per fixture on one- and two-family work, $8 on multi-family and commercial; $50 per water or sewer connection (2026 schedule)
Short-form projectsSheds, driveways, fences and patios, applied for online — shed review typically 3 to 5 business days
Unpermitted workThe applicable permit fee is doubled under Section 8-47(g)(2); non-compliant work may still have to be corrected
Reinspection and other feesPer the current adopted schedule — confirm at filing
⚠️

Start without a permit and the fee doubles — the city’s permit forms cite Section 8-47(g)(2): if a building permit was not obtained before the job began, the applicable permit fee is doubled. The permit card is expected in the front window before work begins.

Trade permits and who may pull them

Trades are state-credentialed; the city adds process, not licenses. All trade permits are submitted with the building permit application, with each contractor's state credential numbers listed.

Permit required

  • Electrical — state license; permit whenever more than three outlets are added without a building permit, and always alongside one
  • Plumbing — state Master Plumber license required to work in the city; witnessed testing under SPS 382.21
  • HVAC — state DSPS registration; permits for any heating work
  • One- and two-family general work — state Dwelling Contractor plus Qualifier, verified before issuance

Typically exempt

  • Owner-occupants on an existing single-family dwelling they live in — with the Homestead affidavit on electrical work
  • Minor repairs below the ordinance triggers

How to apply for a Green Bay building permit

1. Confirm the parcel is city, not town

The Town of Green Bay and five suburbs permit separately; postal addresses mislead.

2. Pick the right form

Short form for sheds, driveways, fences and patios; long form for everything else and all commercial.

3. List every contractor and credential

Trade permits ride with the building application, credential numbers included.

4. Clear Landmarks if the property is historic

Certificate of Appropriateness first; the Commission meets the third Wednesday at 4:30 p.m.

5. File and wait in order

Applications process in the order received; the city currently quotes about one week for building permits once everything is in, and 3 to 5 business days for a shed.

6. Book the witnessed plumbing test

Notify the Division ahead; the inspector watches the sanitary and DWV test.

Review, corrections and what actually causes delay

Green Bay works its queue strictly in order of receipt, so the practical lever is a complete first submission — contractor credentials listed, the right form, Landmarks cleared. The witnessed-test rule adds one scheduling step other cities skip; missing it stalls the plumbing close-out.

Inspections in Green Bay

Inspections run footing, foundation, tar-tile-stone, framing and rough-in, insulation and final on the building side, with erosion-control pre-construction meetings scheduled through Community and Economic Development. Request inspections online by 4:00 p.m. at least one business day ahead, or call (920) 448-3300.

Does Green Bay license HVAC contractors?

Not anymore. The city's commercial permits page states the former city licensing requirement is no longer in effect; state DSPS registration still applies.

When does electrical work need a permit on its own?

When more than three outlets — receptacles, lights or switches — are added without a building permit. Minor repairs sit below the trigger.

What is the witnessed plumbing test?

Since October 1, 2021 the city requires sanitary and interior drain, waste and vent installations to be tested with the plumbing inspector watching, under SPS 382.21.

What happens if work starts before the permit?

The applicable permit fee is doubled under Section 8-47(g)(2), as printed on the city’s permit forms.

Who reviews large commercial plans?

The city holds all-size delegation and contracts the review to E-Plan Exam, so plans stay in the city's process rather than the state queue.

Which code governs my house?

The Wisconsin Uniform Dwelling Code, SPS 320 to 325. Wisconsin never adopted the International Residential Code.
