Enforceability Status

Likely Enforceable

Material substitution clauses in Michigan new construction contracts are likely enforceable. Michigan courts generally uphold freedom of contract. The Michigan Consumer Protection Act (MCLA section 445.901 et seq.) provides consumer protections against deceptive practices, though the Michigan Supreme Court has limited its application to certain regulated transactions.

Legal Analysis

Michigan courts follow freedom-of-contract principles and generally enforce builder contract provisions as written. Material substitution clauses permitting the builder to replace specified materials with alternatives of comparable quality are treated as valid contractual terms.

The Michigan Consumer Protection Act (MCPA), MCLA section 445.901 et seq., prohibits unfair, unconscionable, or deceptive methods in trade or commerce. However, the Michigan Supreme Court's decision in Smith v. Globe Life Insurance Co. (2004) held that the MCPA does not apply to claims arising from conduct specifically authorized by a regulatory scheme. This may limit MCPA claims related to licensed construction activities in some circumstances.

Michigan recognizes an implied warranty of habitability and fitness in new home construction. The Michigan Supreme Court recognized this warranty in Weeks v. Slavick Builders, Inc. (1966). Material substitutions that compromise habitability may breach this implied warranty.

The Michigan Construction Code, adopted pursuant to MCLA section 125.1501 et seq. (Michigan Building Code Act), establishes statewide minimum construction standards. Material substitutions must comply with the Michigan Construction Code. The Bureau of Construction Codes within the Department of Licensing and Regulatory Affairs oversees enforcement.
