Oshkosh writes its permit list down to the specific: re-siding needs a permit and the house numbers must go back up afterwards; roofing needs a permit and may cover no more than one existing layer of shingles; metal roofs are not allowed on residential buildings unless they meet city guidelines and are approved.
Inspection Services operates from Room 205 of City Hall at 215 Church Avenue, 7:30 a.m. to 4:30 p.m. weekdays, with homeowners and contractors able to apply online for building and mechanical permits, upload plans, and pay electronically — construction may not begin until payment clears and the permit issues.
This guide covers the City of Oshkosh. The separate Town of Oshkosh contracts its permitting to a private inspection firm, and Neenah, Menasha and the surrounding towns permit independently — so a mailing address is not a jurisdiction.
Roofing is a permitted, restricted activity here. The city's permit list requires a permit to install or replace roofing and states that shingles may be installed over no more than one layer of existing shingles. It goes further on material: metal roofs are not allowed on residential buildings in the city unless they meet certain guidelines and are approved by the city.
What requires a building permit in Oshkosh?
Wisconsin splits construction into two statewide instruments, and neither one is a city invention. One- and two-family homes run on the Wisconsin Uniform Dwelling Code (SPS 320 to 325), a code Wisconsin wrote for itself — the state never adopted the International Residential Code, so IRC chapter references from other states simply do not apply here. Everything that is a public building or a place of employment, including any residential building of three or more units, runs on the Wisconsin Commercial Building Code (SPS 361 to 366), which moved to the 2021 I-codes effective September 1, 2025; plans submitted on or after November 1, 2025 must comply with the 2021 editions. Under Wis. Stat. 101.65(1c) and 101.02(7r)(a), Oshkosh may not enforce different technical standards — local ordinances must strictly conform to the state codes.
Typically permit required
- New construction and additions on both tracks
- Alterations and remodeling, including cabinets and drywall work
- Detached garages, lean-tos, storage buildings and gazebos — including pre-fabricated and off-site-built sheds placed on the lot
- Stairs, decks, stoops, porches and ramps, built or rebuilt
- Re-siding and reroofing, with the one-layer shingle limit and the residential metal roof restriction
- Moving a constructed building into or out of the city
Often exempt
- Interior painting and wallpapering
- Pouring a concrete sidewalk up to four feet wide
- Replacing a faucet and similar like-for-like fixture swaps
- Buildings used for farming — exempt from the state code under Wis. Stat. 101.05(5), with farming defined by DSPS rule; a produce stand stays exempt only while the farmer raised substantially all of what it sells
- Primitive rural hunting cabins — carved out of municipal jurisdiction by Wis. Stat. 101.65(1g)
- Bed-and-breakfast establishments as defined by statute (Wis. Stat. 101.05(2))
What is actually local, and what is not
Oshkosh enforces the state codes and layers city ordinance chapters over them — building at Chapter 7, electrical at Chapter 11, plumbing at Chapter 20, housing at Chapter 16. Note the city's published code listing still names the 2015 I-code editions, which the state superseded on September 1, 2025; submit commercial plans to the current editions and confirm the local reference at the counter.
Who handles permitting in Oshkosh?
Inspection Services issues permits, reviews plans and inspects, with a chief building official who also serves as plumbing inspector and a bench of commercial building, electrical and housing inspectors. Oshkosh holds second-class-city delegation covering commercial buildings of all sizes, with review performed by E-Plan Exam.

Permit types
Residential permits
Houses run on the Uniform Dwelling Code, permitted online or at Room 205, with state Dwelling Contractor and Qualifier certifications checked before issuance. The residential building guides published by the city are worth reading before scoping — they carry the roofing, siding and accessory-building rules that catch people out.
How Wisconsin contractor licensing works
Wisconsin has no state general contractor license for commercial work — the city's own forms note that 2013 Wisconsin Act 20 ended state building-contractor registration on July 2, 2013. For one- and two-family work the state requires a Dwelling Contractor certification on the business and a Dwelling Contractor Qualifier on an individual, and under Wis. Stat. 101.65(1m) Oshkosh may not issue a building permit to a contractor who cannot produce them; owner-occupants are exempt. Electricians and plumbers are licensed statewide by DSPS. HVAC contractors only register with the state — there is no state HVAC license — which is exactly where local rules step in. Oshkosh adds no municipal trade license; its local layer is in the ordinance chapters and the published construction rules.
Commercial permits
Commercial submittals route through the city's all-size delegation with E-Plan Exam reviewing. Plan approval precedes the permit, and the statewide sealing and supervising-professional requirements attach at fifty thousand cubic feet. Submit to the current code editions rather than the older ones some reference material still cites.
Mechanical work, and where the state reviews directly
Commercial plan review in Wisconsin is a two-step: under Wis. Stat. 101.12(3)(h) the plan approval comes first and the local permit cannot issue without it. The state review trigger is 25,000 cubic feet, plus categorical triggers at any size for schools, high-hazard occupancies and residential buildings of three or more units. At 50,000 cubic feet plans must be prepared, signed and sealed by a Wisconsin-registered design professional, with a supervising professional retained for construction observation. Commercial plumbing plans go to review at sixteen or more fixtures.
Oshkosh permit costs and fees
Permits are applied for and paid online or by check, and no construction may begin until payment is received and the permit issued. The city also publishes a permit refunds policy for projects that do not proceed.
| Item | Fee or rule |
|---|---|
| Building and mechanical permits | Applied for and paid online; card payments carry an additional processing fee |
| Start of work | Not permitted until payment is received and the permit obtained |
| Refunds | Governed by the city's published permit refunds policy |
| Trade and reinspection fees | Per the current adopted schedule at filing |
Two rules that stop roofing jobs. Shingles may go over no more than one existing layer, and metal roofs are not allowed on residential buildings in the city unless they meet the guidelines and are approved — settle both before the material is ordered.
Trade permits and who may pull them
Trades are state-credentialed and permitted by the city, with dedicated electrical, plumbing, commercial building and housing inspectors on staff.
Permit required
- Electrical — state license; city permit and electrical inspection
- Plumbing — state license; the chief building official also serves as plumbing inspector
- HVAC — state registration; mechanical permits available online
- One- and two-family general work — state Dwelling Contractor plus Qualifier
Typically exempt
- Faucet replacement and comparable like-for-like fixture work
- Interior painting, wallpapering and similar finishes

Frequently asked questions
Can I put a metal roof on my house in Oshkosh?
Not by default. The city states metal roofs are not allowed on residential buildings unless they meet certain guidelines and are approved by the city.
How many layers of shingles can I roof over?
One. The city's permit page limits new shingles to installation over no more than one layer of existing shingles.
Do I need a permit to re-side my house?
Yes — and the city reminds owners to reinstall the house numbers when the work is done.
Which projects do not need a permit?
Interior painting and wallpapering, pouring a sidewalk up to four feet wide, and like-for-like work such as replacing a faucet.
Which code editions apply to commercial work?
The 2021 editions: they took effect September 1, 2025, with mandatory compliance for plans submitted on or after November 1, 2025. Some local reference pages still list the older editions.
