Bonding in Wisconsin

A surety bond is a 3-party agreement. The contractor pays a surety company an annual premium. The state or city (obligee) can require a claimant to recover from the bond if the contractor violates the rules tied to the bond. The surety pays valid claims up to the bond face value and then pursues the contractor for reimbursement. A bond protects the public. It is not insurance for the contractor. In Wisconsin the bonding question depends on what you are bidding and in what city. The state does not require a general contractor bond. The bond picture breaks into 3 layers. 1. Dwelling Contractor Certification (DSPS). Wisconsin Department of Safety and Professional Services requires applicants for Dwelling Contractor Certification to show financial responsibility through liability insurance and, for many applicants, a surety bond. Wisconsin administrative code SPS 305.31 and related sections describe a tiered structure. An applicant who files a surety bond of less than $25,000 receives a Dwelling Contractor, Restricted Certification, which carries a card notation reading "Financial Responsibility: by a bond under $25,000 Certification." An applicant who meets the full financial responsibility requirement (including a bond at or above the $25,000 threshold, when a bond is used) receives the standard Dwelling Contractor Certification. Verify the current bond rule, amounts, and form requirements (SBD-10679) on the DSPS application before you buy. 2. Municipal contractor registration. Most Wisconsin cities require contractors working in their limits to register locally, and many require a local bond in addition to the DSPS credential. Commonly cited examples: - City of Madison. The Department of Engineering requires a $5,000 license and permit bond for registered contractors. - City of Milwaukee. Electrical, plumbing, concrete, and home improvement contractors are required to be bonded before they can obtain a permit. Amounts and categories vary by trade and are set by the city. Verify the bond amount and rule directly with the city before you bid. Each municipality writes its own ordinance. 3. Trade credential bonds. DSPS-issued individual trade licenses for electricians and plumbers may carry separate credential-level bond or insurance requirements tied to contractor registration. Confirm with DSPS for the specific credential you hold. Premium math. A surety typically charges 1% to 3% of the bond face value per year for a contractor with strong personal credit and no prior claims. Weaker credit or a new business can run 5% to 10% or more. A $25,000 bond at 2% costs $500 per year. A $5,000 Madison city bond at a similar rate costs about $100 per year. What claims look like. A customer, supplier, or employee files a complaint with DSPS or the relevant city department. If the complaint is found valid and falls within the bond's covered conduct, the claimant can recover from the bond up to the face value. The surety pays, then pursues the contractor for reimbursement.
