Starting Thursday, July 1, landlords must provide carbon-monoxide detectors before they can rent out any dwelling that has a carbon-monoxide source.

Starting Thursday, July 1, landlords must provide carbon-monoxide detectors before they can rent out any dwelling that has a carbon-monoxide source.

The new requirement follows passage of House Bill 3450 by the 2009 Oregon Legislature, also called the Lofgren and Zander Memorial Act.

The deadline effects only new rentals, but by April 2011 all dwellings that have carbon-monoxide sources will need to have carbon-monoxide detectors before they can be rented, remodeled or sold.

Carbon-monoxide sources include fuel-fired appliances such as water heaters, furnaces, clothes dryers, ranges, stoves, fireplaces and wood stoves.

Starting on Thursday, when a landlord enters into a new rental agreement for a dwelling unit that contains a carbon-monoxide source, the landlord must ensure the dwelling contains one or more properly functioning carbon-monoxide alarms at the time the tenant moves in. The landlord must provide the new tenant with alarm-testing instructions, and if the alarm is battery operated or has a battery backup system the landlord must supply working batteries for the alarm.

On April 1, 2011, the rules will apply to all rentals. Also on April 1, all one- and two-family dwelling or multifamily housing units that contain a carbon-monoxide source must have carbon-monoxide alarms installed in all sleeping areas before the property can be sold or remodeled.

The same requirement will apply to new construction as well.
