Home improvement projects—also known as home repairs, renovations, or remodeling—range from small painting projects to complete reconstruction of rooms or of an entire home.

Home improvement projects can present a number of potential legal issues, including financing and loans (home equity line of credit or HELOC, for example); the construction contract for the work (materials and labor); surveys and lot lines; mechanic’s liens; waivers or releases of mechanic’s liens; insurance against damage or loss (builder’s risk) to the home or materials; and worker’s compensation insurance to insure against personal injuries sustained by a contractor or subcontractor.

In Wisconsin, home improvement projects are subject to various legal considerations. Financing such projects often involves a home equity line of credit (HELOC) or other loans, which are regulated by state and federal lending laws. The construction contract, which details the scope of work, materials, labor, and payment terms, is a critical legal document that should comply with Wisconsin's Home Improvement Practices Act. This Act requires specific provisions in home improvement contracts and regulates the conduct of contractors. Surveys and lot lines must be respected to avoid trespass or encroachment issues. Mechanic’s liens are a legal tool for contractors and subcontractors to secure payment for their work and materials provided; however, property owners may require waivers or releases of mechanic’s liens as part of the payment process. Insurance, such as builder’s risk policies, protects against damage or loss during the project, while worker’s compensation insurance is mandatory for contractors with employees to cover personal injuries on the job. It is advisable for homeowners to consult with an attorney to navigate these legal aspects and ensure compliance with all relevant laws and regulations.
