Wisconsin Dwelling Contractor Registration

Register with DSPS before building or remodeling any one- or two-family dwelling. Wisconsin requires business registration under SPS 305.31 (Wis. Stat. § 101.654) for any company that constructs, adds to, alters, or repairs one- and two-family residential buildings. The annual registration must stay active to offer covered work or pull building permits.

What triggers registration — and what is excluded

Registration covers all work on one- and two-family dwellings subject to Wisconsin Uniform Dwelling Code (SPS 320–325): new construction, additions, alterations, and repairs. Two common exclusions:

• Owner-occupants building or renovating their own home are exempt under Wis. Stat. § 101.654(1)(b)
• Electrical, plumbing, and HVAC contractors — those trades are separately licensed and excluded from the dwelling contractor scope under SPS 320.07

A Dwelling Contractor Qualifier must be on staff

Every registered business must employ or sponsor at least one Dwelling Contractor Qualifier (DCQ) — a separate individual DSPS credential. The DCQ completes a 12-hour DSPS-approved initial course (not a proctored state exam; the provider's embedded quiz requires a 70% passing score) and renews every 2 years with 12 hours of CE per cycle. No field experience prerequisite. The DCQ's knowledge of SPS 320–325 is what validates the business registration.

Fees: $25 annual renewal, $40 application

Both fees are paid to DSPS — application at initial registration, $25 at each annual renewal.

• Application fee: $40
• Annual renewal fee: $25
• Late penalty: $25 flat DSPS processing fee (30-day grace period)

Financial responsibility: insurance or bond required

Under Wis. Stat. § 101.654(2), every registered dwelling contractor must maintain one of:

• General liability insurance at the minimum required under § 101.654(2)(a)
• A surety bond per § 101.654(2)(a)1 — minimum bond amounts and project-cost restrictions are set by § 101.654(2m)

Workers' compensation is required where applicable under Wisconsin ch. 102.

Building permits come from the municipality, not DSPS

Dwelling contractor registration is a state credential; the uniform building permit is issued by the local municipality. Pull the permit before starting construction — proceeding without one is grounds for DSPS discipline under SPS 305.10(1)(a)14(b).

Penalties

Standard violations (Wis. Stat. § 101.599(3)(a)): up to $1,000 per violation. Willful or pattern violations (§ 101.599(3)(b)): up to $10,000 per violation.
