In Michigan's construction industry, adhering to the manufacturer's installation instructions is not just best practice—it's a legal and safety imperative. Whether you're building a new home in Grand Rapids or remodeling in Detroit, following these guidelines ensures compliance with state codes, enhances safety, and protects your business from costly liabilities.
Legal Compliance: It’s the Law
Michigan’s building codes explicitly require builders to follow manufacturer-provided installation instructions. For example, Section R106.1.2 of the 2015 Michigan Residential Code states that these instructions must be available on-site during inspections (codes.iccsafe.org). This requirement applies to a wide range of components, from HVAC systems to windows and doors.
Additionally, Michigan Administrative Code R. 125.1602 mandates that manufactured homes be installed according to the manufacturer’s instructions (law.cornell.edu). Failure to comply can lead to inspection failures, project delays, and potential legal action.
Safety and Performance
Manufacturer instructions are designed to ensure that products function safely and efficiently. For instance, improper installation of recessed lighting fixtures can pose fire hazards. Michigan code R408.30538 requires that such fixtures be installed per the manufacturer’s guidelines to prevent risks associated with heat and electrical faults (dtmb.state.mi.us).
Similarly, mechanical systems like ductless range hoods must be installed following the manufacturer's instructions to ensure proper ventilation and indoor air quality (michigan.gov).
Protecting Your Business
Non-compliance with installation instructions can have serious repercussions. Beyond safety concerns, it can void product warranties and expose builders to legal liabilities. In Michigan, unlicensed or non-compliant contractors have faced increased legal actions, including over 200 misdemeanor cases in 2022 alone (method.me).
Moreover, failing to adhere to manufacturer guidelines can lead to construction liens, where contractors, subcontractors, or suppliers may claim unpaid compensation against a property (buildwithcam.com).
