What does a contractor or trade need in Waukesha County that other businesses do not?

3 of the 3 permits particular to a contractor or trade here apply to no other business type we cover in Waukesha County: Stormwater / Erosion Control Permit Plan Review, Dwelling Contractor Certification and General Contractor Licensing — Wisconsin Trades Credential List.

Stormwater / Erosion Control Permit Plan Review

A contractor or developer disturbing land or adding impervious surface on unincorporated land in Waukesha County needs a stormwater permit from the Land Resources Division of the Department of Parks and Land Use. County Code §14-331(a) applies the ordinance to "all unincorporated lands within the jurisdictional boundaries of Waukesha County, unless a town board" adopts its own compliant ordinance. The LRD decides whether a project needs only an erosion control plan (Type 1) or a full stormwater management plan (Type 2, for example buildings and parking lots adding 0.5 acres or more of impervious surface). The fees are from the county's sheet "Stormwater Permit Plan Review Fees – 2026", dated 1/1/2026; §14-334(e)1 says fees are "established by the LRD and approved by the County Board through the annual budget process", and §14-334(e)4 exempts publicly funded activities. The $275 component is the State DNR NR 216 fee, listed on the county sheet. A financial assurance is a condition of the permit.

Dwelling Contractor Certification

Two credentials that interlock rather than substitute. The dwelling contractor certification is the business's — it is what lets a firm contract for work on one- and two-family dwellings and pull building permits — and the business must additionally hold, or employ someone who holds, the individual dwelling contractor qualifier credential, which renews at $30 and requires a twelve-hour approved course within the year before applying. The money that matters is not the fee: the business must show financial responsibility of at least $25,000 by bond or insurance, plus liability cover of at least $250,000 per occurrence. The department's credential fee table sets the initial fee for the business certification at $25 plus a $15 application fee, and for the qualifier credential at $30 plus a $15 application fee. Reinstatement is $200. Note this reaches residential work only; the department's trades fee table lists no general or commercial building contractor credential.

General Contractor Licensing — Wisconsin Trades Credential List

No fee is recorded. The Department of Safety and Professional Services' published table of trades credential fees lists every contractor credential the department issues — automatic fire sprinkler contractor and its maintenance variant, dwelling contractor and dwelling contractor restricted, electrical, elevator, HVAC and utility contractor — and that table lists no general or commercial building contractor credential. On that schedule, state-level contractor credentialing reaches residential work on one- and two-family dwellings, through the dwelling contractor scheme, and the specific trades. A commercial project still needs plan review and permits, and any electrical, plumbing, HVAC, fire sprinkler or elevator work must be done by the relevant licensed trade. Municipalities may register contractors separately.

The other 5 local permits in the tables apply to every type of business in Waukesha County, WI; what each one involves is set out on the Waukesha County permits page. The 4 state-level registrations apply to every type of business across WI and are covered on the WI state page.
