Wisconsin Homeowner-Contractor Agreement

Instructions — not part of the agreement

How to Use This Template

This template was built by jaspector.com to help Wisconsin homeowners protect themselves when hiring a contractor. It covers the key provisions relevant to Wisconsin law, including license verification, mechanics' lien protections, and the Home Solicitation Sales Act.

Before You Start

1. Verify the contractor's license. Use the applicable state licensing portal to confirm the license is active, the classification covers your project, and the bond and workers' comp are current. See our Wisconsin license lookup guide for step-by-step help.
2. Download and print this document. Fill in all blank fields — do not leave any section empty.
3. Review each Wisconsin callout. These notes highlight state-specific legal protections. Read them carefully — they explain your rights as a homeowner.
4. Both parties sign. You and the contractor each get a signed copy before any work starts.
5. Consult an attorney. This template is a starting point. For large projects or complex scopes, have a Wisconsin-licensed attorney review the agreement.

Field-by-Field Guide

• ›Section 1 (Parties): Fill in legal names exactly as they appear on official documents. The contractor's certification number.
• ›Section 2 (Scope): Be as specific as possible. "Kitchen remodel" is not enough — list materials, dimensions, finishes, and what is excluded.
• ›Section 3 (Payment): Wisconsin does not impose a statutory cap on down payments. Limit the down payment to no more than 1/3 of the contract price. Tie every payment to a completed milestone, not a calendar date.
• ›Section 4 (Timeline): Get start and completion dates in writing. Fill in the delay penalties — these protect you if the contractor falls behind.
• ›Section 7 (Warranties): Fill in the warranty period. One year is common; negotiate for more on major work.
• ›Section 14 (Exhibits): Attach all plans, specs, and the contractor's license printout. Check each box for what you are including.
