Do I need a carbon monoxide detector in my house?

Carbon monoxide is a colorless, odorless gas that can only be detected with a metering device. Since March 31, 2006, every residential structure that presently or in the future contains Fossil Fuel Burning Equipment or has enclosed parking shall be equipped, by the owner, landlord, or Superintendent, with working listed Carbon Monoxide Alarm protection. A detector shall be located in each level of each dwelling unit including habitable portions of basements, cellars, and attics, but not including crawl spaces. When mounting a carbon monoxide alarm on a level of a dwelling unit with a sleeping area, the alarm shall be installed in the immediate vicinity of the sleeping area. At a minimum, the alarm shall be located outside of any bedroom, but shall not exceed ten feet in any direction from any bedroom door.
