Madison contractor license lookup: the Wisconsin Dwelling Contractor credential, trade licenses and the permit record

Which license each job needs in Madison

DSPS describes the Dwelling Contractor as the credential for "the owner, partner, or chief executive of a contracting business seeking certification to obtain building permits for one- and two-family dwellings" (DSPS, read 26 October 2026). The statute behind it says "no person may obtain a building permit" without the certificate of financial responsibility and continuing education it requires (Wis. Stat. § 101.654(1)(a)).

How to run the lookup in five minutes

1. Ask for the credential number of the business, and for the electrician's, plumber's or HVAC contractor's license if they are separate firms.
2. Search each one in DSPS's License Lookup, linked from the DSPS home page. Check that it is active and that the type fits the job: a Dwelling Contractor for a remodel, a plumbing license for a water heater.
3. See the firm's Madison jobs. In the City's Accela Citizen Access, search by contractor license information, as the Madison building permit search guide shows.
4. Look up your address in the same portal before you buy or hire, to see what was permitted there before.

Doing the work yourself

State law lets an owner-occupant pull their own building permit: the Dwelling Contractor rule "does not apply to an owner of a dwelling who resides or will reside in the dwelling and who applies for a building permit to perform work on that dwelling" (§ 101.654(1)(b)). Plumbing is exempt for "a property owner in a one-family building owned and occupied by him or her" as a home, "except where such license is required by local ordinance" (§ 145.06(4)(a), read 26 October 2026). Madison's own ordinance can add to that, so call the City's Development Services Center (608-266-4551) before you start electrical, plumbing or HVAC work yourself.

What our Madison pages add

The DSPS lookup answers "is this firm licensed". Our Madison page counts what the City permitted, October 2024 to September 2026, and 95% of those permits name a contractor:

Roofing permits more than tripled, from 2,506 in October 2024 to September 2025 to 8,352 in the twelve months after. The landing and each kind-of-work page list the contractors named on the most permits, a count of volume only. Madison's permit rules: roofing, plumbing and HVAC.

What this lookup does not tell you

Madison's permit reports have no status or final inspection date, so we cannot say which jobs were finished, and we have not matched the named contractors to DSPS credentials. A busy firm is not necessarily a good one, and a license says the firm may do the work, not how its last job went.
