# Wisconsin

> Trade credentials, dwelling contractor certification, regulator routing, requirements, reciprocity, and license types for Wisconsin's trade-credential construction regulation model.

Wisconsin does not license general contractors at the state level. Instead, it regulates specific construction trades — plumbing, electrical, fire sprinkler, blasting, HVAC, and dwelling construction — through the Department of Safety and Professional Services (DSPS). Dwelling contractors must hold a financial responsibility certification with a **\$25,000** bond. Highway prequalification runs separately through WisDOT.

<Warning>
  Always verify statutes, fees, and application details with the live regulator before making bidding, licensing, or legal decisions.
</Warning>

## At a glance

The fastest way to orient yourself in Wisconsin is to understand that the state regulates trades, not general contractors. The key question is whether your work falls into a credentialed trade.

<Tabs>
  <Tab title="Contractors" icon="hard-hat">
    <AccordionGroup>
      <Accordion title="What trades require state licensing in Wisconsin?">
        Wisconsin requires state trade credentials for plumbing, electrical, fire sprinkler, blasting, HVAC, storage tanks, and asbestos. Dwelling contractors building one- or two-family homes need a financial responsibility certification with a **\$25,000** bond. There is no general contractor license. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="What is the financial responsibility certification for dwelling contractors?">
        If you build one- or two-family dwellings, you need a financial responsibility certification from DSPS. This requires proof of workers' compensation, unemployment compensation, liability or bond insurance, and a **\$25,000** bond. You must also employ someone with a Dwelling Contractor Qualified Certification (obtained through training). A bond under **\$25,000** gets a restricted certification. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Does Wisconsin require prequalification for highway work?">
        Yes. All highway bidders must prequalify with WisDOT. For ratings above **\$500,000**, a CPA-reviewed or audited financial statement is required. Prequalification is good for two years. Payment and performance bonds plus a proposal guaranty are required. Submit at least 10 business days before bid opening. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Where do I go to get licensed in Wisconsin?">
        DSPS (Department of Safety and Professional Services) handles all trade credentials and dwelling contractor certification. WisDOT handles highway prequalification. There is no separate contractor licensing board. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="How much does it cost to get licensed?">
        Costs vary by trade. Plumbing journeyman credential: **\$180**. Master plumber: **\$500**. Fire sprinkler contractor: **\$2,000**. Fire sprinkler journeyman: **\$180**. Blaster: **\$100**. Dwelling contractor financial certification requires a **\$25,000** bond. Most trade licenses run on four-year terms. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Can I use my out-of-state license in Wisconsin?">
        Wisconsin has a single reciprocity agreement — with Iowa for Master and Journeyman Electricians only. No other trade or contractor reciprocity exists at the state level. See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="Does Wisconsin require a license for residential construction?">
        If you are building one- or two-family dwellings, you need the DSPS financial responsibility certification with a **\$25,000** bond. Owners who occupy or will occupy the dwelling are exempt. Trade-specific work (plumbing, electrical) still requires separate credentials. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="What is the exam requirement for trade credentials?">
        Most trade exams require a 70% minimum score. This applies to plumbing (journeyman, master, utility contractor), fire sprinkler, and blasting credentials. Blaster applications must be filed 30 days prior to the examination date. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What experience is needed for a plumbing license?">
        Journeyman plumber: complete an apprenticeship program. Master plumber: 1,000 hours per year for three consecutive years as a licensed journeyman in Wisconsin, or an approved engineering degree. Both require a 70% minimum exam score. License terms are four years with continuing education required. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="Does Wisconsin require a license for roofing work?">
        Roofing is not separately credentialed at the state level beyond the dwelling contractor financial certification requirement (if the roofing is part of one- or two-family dwelling construction). Commercial roofing has no state-level credential requirement. Check local municipality requirements.

  <Tab title="Regulators" icon="shield-check">
    <AccordionGroup>
      <Accordion title="How does Wisconsin's licensing model compare to other states?">
        Wisconsin is a trade-credential state with no general contractor license. Two agencies — DSPS and WisDOT — handle all state-level regulation. The state controls quality through trade-specific exams and financial requirements rather than general contractor classification. This is structurally similar to Michigan's BCC model. See [Construction work regulated](#construction-work-regulated).
      </Accordion>

      <Accordion title="How does the $25,000 dwelling bond compare to other states?">
        The **\$25,000** financial responsibility bond for dwelling contractors is a distinctive feature. Many states either do not require a bond for residential work or set different thresholds. Wisconsin also offers a restricted certification for bonds under **\$25,000**. Owner-occupants are exempt. See [Licensing thresholds](/docs/compare/licensing-thresholds).
      </Accordion>

      <Accordion title="What is regulated at the state vs. local level in Wisconsin?">
        The state regulates trades (plumbing, electrical, fire sprinkler, blasting, HVAC, storage tanks, asbestos) and dwelling construction through DSPS, plus highway work through WisDOT. General commercial construction and most other work is left to local jurisdictions.
      </Accordion>

      <Accordion title="What agencies handle construction in Wisconsin?">
        Two agencies: DSPS (Department of Safety and Professional Services) for all trade credentials and dwelling contractor certification, and WisDOT for highway prequalification. This dual-agency model is simpler than states with multiple independent boards. See [Who regulates construction](#who-regulates-construction).
      </Accordion>

      <Accordion title="What are the fees across trades?">
        Plumbing master: **\$500** credential. Fire sprinkler contractor: **\$2,000** credential. Blaster: **\$100** credential. Plumbing journeyman: **\$180**. Fire sprinkler journeyman: **\$180**. Application fees range from **\$10** to **\$25**. Exam fees range from **\$20** to **\$100**. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What license classifications does Wisconsin use?">
        Wisconsin offers credentials across dwelling construction, fire sprinkler, plumbing, blasting, electrical, mechanical, and storage tanks. The plumbing category alone includes 11 credential types. Electrical offers 7 types. Fire sprinkler has 7 types. See [Types of licenses](#types-of-licenses).
      </Accordion>

      <Accordion title="How does reciprocity work in Wisconsin?">
        Wisconsin has extremely narrow reciprocity — only Iowa for Master and Journeyman Electricians. No other trade or contractor reciprocity exists. This makes Wisconsin one of the most restrictive states for out-of-state credential recognition. See [Reciprocal agreements](#reciprocal-agreements).
      </Accordion>

      <Accordion title="What exam requirements exist?">
        Most trades require a 70% minimum score on knowledge, law, and/or trade exams. Blasters need 640-2,000 hours of experience depending on class. Plumbing masters need three consecutive years as a licensed journeyman in Wisconsin (1,000 hours/year). Fire sprinkler contractors face the highest credential fee at **\$2,000**. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="What are the renewal cycles?">
        Most trade credentials run on four-year terms, which is longer than the annual or biennial cycles in many other states. Blaster licenses are also four years. Highway prequalification is valid for two years. Dwelling contractor certification renewal timing varies. See [Requirements](#requirements).
      </Accordion>

      <Accordion title="How does Wisconsin compare to other Midwest states?">
        Wisconsin's trade-credential model is moderately structured — more comprehensive than Kansas or Missouri, comparable to Michigan, and less complex than Ohio's five-agency system. The four-year license terms and dual-agency structure (DSPS + WisDOT) are distinctive in the region. See the [Midwest region guide](/docs/jurisdictions/regions/midwest).

## Special considerations

Different roles need different things from a Wisconsin page. Use the tab that matches your situation to see what matters most before you read the full detail below.

<Tabs>
  <Tab title="Contractors" icon="hard-hat">
    <Tip>
      Wisconsin does not have a general contractor license. Ask instead: does my work fall into a regulated trade? If you are building one- or two-family dwellings, you need financial responsibility certification with a **\$25,000** bond.
    </Tip>

    * No state-level general contractor license exists.
    * Dwelling contractors need a financial responsibility certification (**\$25,000** bond; less than **\$25,000** = restricted certification).
    * Dwelling contractors must also employ a person with a Dwelling Contractor Qualified Certification (obtained through training).
    * Trade credentials are required for plumbing, electrical, fire sprinkler, blasting, HVAC, and storage tank work.
    * Highway prequalification requires financial statements. CPA-reviewed or audited statement needed for ratings above **\$500,000**.
    * All contractors must provide a payment and performance bond at contract execution.
  </Tab>

  <Tab title="Regulators" icon="shield-check">
    <Info>
      Wisconsin is best understood as a trade-credential state, not a general-license state. Two agencies — DSPS and WisDOT — handle all state-level construction regulation.
    </Info>

    * DSPS administers all trade credentials through its Trades Credentials Unit.
    * WisDOT administers highway prequalification separately.
    * No general contractor board exists. The state controls quality through trade-specific exams and financial requirements.
    * Reciprocity is minimal: Iowa only, for electricians.

## Readiness checklist

Four things you need to confirm before you can treat Wisconsin as "ready" for a bid or an application. If any of these are unclear, you are not ready yet.

<Steps>
  <Step title="Determine if your trade is regulated" icon="tag">
    Wisconsin does not license general contractors. Identify whether your work involves a regulated trade (plumbing, electrical, fire sprinkler, blasting, HVAC, dwelling construction, or storage tanks).
  </Step>

  <Step title="Check financial requirements" icon="currency-dollar">
    Dwelling contractors need a `$25,000` bond. Highway prequalification requires financial statements; ratings above `$500,000` require a CPA-reviewed or audited statement. Payment and performance bonds are required at contract execution.
  </Step>

  <Step title="Route to DSPS or WisDOT" icon="building-bank">
    DSPS handles all trade credentials and dwelling contractor certification. WisDOT handles highway prequalification. There is no separate contractor board.
  </Step>

  <Step title="Confirm the credential requirements" icon="clipboard-check">
    Confirm exams (70% minimum for most trades), experience hours, continuing education, and renewal cycles for your specific credential before filing.
  </Step>
</Steps>

<Check>
  If you can determine your trade, confirm financial requirements, route to the correct agency, and verify credential requirements, you have the minimum package needed for a Wisconsin readiness check.

## Reciprocal agreements

Wisconsin has a single reciprocity agreement — with Iowa for Master and Journeyman Electricians. No other trade or contractor reciprocity exists at the state level.

<Info>
  Wisconsin reciprocity is extremely narrow. Only Iowa electricians benefit from a reciprocal arrangement.
