HB 4582 Michigan House · 2025-2026 Regular Session

Torts: premises liability; open and obvious defense; provide for. Creates new act.

HB 4582, the "Commercial Premises Liability Act," establishes new rules for property owners regarding injuries to customers (invitees) on their premises. It creates a defense for property owners against liability claims when a hazard is "open and obvious" (e.g., a clearly visible spill), meaning they generally don’t need to warn customers about such conditions. However, owners must take reasonable precautions if an obvious hazard has "special features" making it unavoidable or posing severe risk (like a steep, unmarked step). The bill clarifies it doesn’t override existing laws or change comparative fault rules, focusing solely on defining when property owners must act to prevent injuries.
