All Minnesota homes need carbon monoxide detector starting Friday

ST. PAUL -- State law requires that single-family homes in Minnesota have at least one carbon monoxide detector starting Friday. 

Property owners will be responsible for providing all single-family homes with at last one carbon monoxide detector within 10 feet of each bedroom. 

The Department of Public Safety says the alarms will go off when levels of the gas rise high enough to be a health concern. 

The department notes that traditional smoke alarms will not detect carbon monoxide. 

The carbon monoxide alarm law was enacted in 2006, after carbon monoxide buildup from a propane boiler killed a teenager in North Branch. 

The first phase of the law affected new construction and multifamily homes in 2007. Single-family homes are affected by the second phase.
