Quick answer: Wisconsin DSPS licenses plumbers, electricians, and HVAC installers at both the business and individual level, and requires a Dwelling Contractor certification (plus a Dwelling Contractor Qualifier) to obtain building permits for one- and two-family dwellings. There is no separate statewide license for general contractors, roofers, painters, carpenters, landscapers, handymen, or cleaners, though local permits and the Dwelling Contractor rule can still apply.
Wisconsin regulates construction trades through the Department of Safety and Professional Services (DSPS), licensing high-risk trades statewide while leaving many others to local rules or no license at all.
Which trades need a license in Wisconsin?
| Trade | State license required? | Licensing body |
|---|---|---|
| Plumber | State license required | Plumbing is a fully licensed trade. Under Wis. Stat. § 145.06, no person may engage in or work at plumbing in the state unless licensed to do so by the Department. DSPS issues individual Master Plumber and Journeyman Plumber licenses (with restricted-service and restricted-appliance variants), and journeyman work must be performed under the general supervision of a Master Plumber. Apply through the LicensE platform. |
| Electrician | State license required | Wisconsin licenses electrical work at both the business and individual level. Under Wis. Stat. § 101.862 and SPS 305.41, no person or entity may engage in the business of installing, repairing, or maintaining electrical wiring unless licensed as an Electrical Contractor. Individuals hold Master Electrician, Journeyman Electrician (Industrial or Residential), and Electrical Apprentice credentials. |
| HVAC | State registration/certification required | Heating, ventilating, and air conditioning work is regulated statewide. A business must hold a registered HVAC Contractor credential, and it meets that requirement by employing or using a person who holds an HVAC Qualifier certification. A business that uses an HVAC Qualifier is deemed a certified HVAC business and generally cannot be required to obtain a separate local certification to install or service HVAC equipment. |
| General Contractor | Dwelling Contractor cert for homes | Wisconsin does not issue a general "contractor" license as such. However, under SPS 305.31, anyone who obtains a building permit for a one- or two-family dwelling must hold a Dwelling Contractor (or Dwelling Contractor Restricted) certification and must hold or employ a Dwelling Contractor Qualifier. Contractors should also verify local municipal registration and permit requirements for larger commercial projects. |
| Roofer | No statewide trade license | There is no standalone statewide roofing license in Wisconsin; roofer is not listed among DSPS-regulated trade professions. That said, roofing that is part of new-home or dwelling construction can fall under the Dwelling Contractor certification for one- and two-family dwellings, and individual municipalities may require local registration or permits. |
| Painter | No statewide license | Painting is not a DSPS-licensed trade; painters do not appear on the state's list of regulated professions. Note that painting or renovation that disturbs paint in pre-1978 housing may require separate lead-based paint certification through the Wisconsin Department of Health Services, and local business registration may apply. |
| Carpenter | No statewide license | Carpentry is not separately licensed by the state; it is not among DSPS-regulated professions. A carpenter who acts as the permit holder for a one- or two-family dwelling would still need a Dwelling Contractor certification, and local permits apply to the specific work performed. |
| Landscaper | No statewide license | Landscaping carries no statewide occupational license in Wisconsin and is not listed among DSPS trade credentials. Local municipal permits may be required for grading, drainage, or hardscape work, and general business registration applies as usual. |
| Handyman | No statewide license | Wisconsin does not license "handyman" work as a distinct trade. However, a handyman may not perform any work that itself requires a license; plumbing, electrical, or HVAC tasks must be done by the appropriately credentialed trade, and pulling a permit for one- and two-family dwelling construction requires Dwelling Contractor certification. |
| Cleaner | No statewide license | Cleaning services are not a DSPS-regulated construction trade and require no statewide occupational license in Wisconsin. Standard business registration and any applicable local requirements apply, but there is no state trade credential for cleaners. |
Even where no statewide license exists, local municipal permits, business registration, and the Dwelling Contractor rule for one- and two-family homes may still apply.
Who regulates the trades in Wisconsin?
The Wisconsin Department of Safety and Professional Services (DSPS) administers statewide construction-trade credentials through its online licensing platform, LicensE. DSPS licenses or certifies the trades where safety risk is highest, including electrical, plumbing, and HVAC, along with specialty credentials such as automatic fire sprinkler, elevator, boiler, and utility contractor work. Trades that do not appear on the DSPS professions list, such as general contracting, painting, carpentry, landscaping, and cleaning, are not licensed at the state level, though local governments may impose their own registration and permit rules.
The Dwelling Contractor certification, explained
Wisconsin's most important rule for home builders and remodelers is the Dwelling Contractor requirement. Under SPS 305.31, no one may obtain a building permit for a one- or two-family dwelling unless they hold a Dwelling Contractor certification (or a Dwelling Contractor Restricted certification) and hold or employ a Dwelling Contractor Qualifier. The certification is a business credential; it does not test hands-on skill, but it requires proof of general liability insurance (at least $250,000 per occurrence). The Qualifier is an individual who completes required coursework and demonstrates knowledge of the Uniform Dwelling Code; every certified dwelling-contractor business must hold or employ one.
Trades that DO need a state license
Three core mechanical trades are licensed statewide at both the business and the worker level:
- Electrical: Electrical Contractor (business) plus Master, Journeyman (Industrial/Residential), and Apprentice electricians.
- Plumbing: Master Plumber and Journeyman Plumber, with restricted variants; no one may work at plumbing without a DSPS license.
- HVAC: Registered HVAC Contractor (business) and HVAC Qualifier (individual certification).
Trades with no separate state license
Wisconsin does not issue statewide occupational licenses for general contractors, roofers, painters, carpenters, landscapers, handymen, or cleaners; none appear on the DSPS list of regulated professions. This does not mean these trades are unregulated: anyone pulling a permit for a one- or two-family dwelling still needs Dwelling Contractor certification, licensed trade work (electrical, plumbing, HVAC) must be done by credentialed trades, and cities and towns commonly require their own contractor registration, bonds, and permits.
How to get licensed in Wisconsin
- Identify your trade and confirm whether it is DSPS-licensed (electrical, plumbing, HVAC) or unlicensed at the state level (general contracting, roofing, painting, carpentry, landscaping, handyman, cleaning).
- If you build or remodel one- and two-family homes, obtain a Dwelling Contractor (or Dwelling Contractor Restricted) certification and secure the required $250,000 general liability insurance.
- Hold or employ a Dwelling Contractor Qualifier by completing the required coursework, so your business can legally pull dwelling building permits.
- For a licensed trade, apply for the correct individual and business credentials (e.g., Journeyman/Master plus Contractor registration) through the LicensE platform.
- Check with the city, town, or county where you work for any local contractor registration, bonding, and building-permit requirements before starting a job.

Frequently asked questions
Do I need a general contractor license in Wisconsin?
There is no statewide general contractor license. However, to obtain a building permit for a one- or two-family dwelling you must hold a Dwelling Contractor certification and hold or employ a Dwelling Contractor Qualifier under SPS 305.31. Local governments may impose additional registration requirements.
What is a Dwelling Contractor Qualifier?
A Dwelling Contractor Qualifier is an individual who has completed required education on the Uniform Dwelling Code. Every certified Dwelling Contractor business must hold or employ a Qualifier in order to pull building permits for one- and two-family dwellings.
Does a handyman need a license in Wisconsin?
No statewide handyman license exists. But a handyman cannot perform work that itself requires a license; plumbing, electrical, and HVAC work must be done by the appropriate credentialed trade, and permitted one- and two-family dwelling work requires Dwelling Contractor certification.
Are electricians and plumbers licensed by the state?
Yes. DSPS licenses electricians (Electrical Contractor at the business level plus Master, Journeyman, and Apprentice individuals) and plumbers (Master and Journeyman, with restricted variants). No one may work at plumbing without a DSPS license, and electrical contracting requires a state license.
