You’ll need a contract with a builder that covers what’s to be built, what happens if there are changes to plans, costs, performance standards (time for construction, warranties, and so on), and more. A contract describes all parties’ rights and obligations. Construction contract forms in Wisconsin are not standardized or state-approved as are the Offer to Purchase, buyer agency, and listing forms. The Wisconsin Builders Association has prepared a model home construction contract. Be sure the contract protects your interests and that you fully understand it. Your attorney can negotiate and review a construction contract on your behalf. If you’re buying a home that a builder is already building, you’ll most likely use the Offer to Purchase to address most of these issues, especially warranties, amenities, and time for completion.
