Aspen — The city of Aspen issued an administrative order Monday that requires all new homes to be equipped with carbon monoxide detectors.

That means building permits will not be issued until officials have determined those residential structures have a detector outside each sleeping area, and the devices must have an audible signal not less than 70 decibels from those areas.

And it appears the law will go further. The Aspen City Council on Monday passed a first reading of an ordinance that will require all existing residential spaces in the city to be retrofitted to include the detectors by a date not yet certain.

The council will make the final vote on that ordinance during a Jan. 12 public meeting.

Pitkin County commissioners are scheduled to consider an identical ordinance Dec. 17. Commissioners will consider the measure as an emergency ordinance, which allows for its quick adoption and implementation.

The requirement on new structures in the city is effective immediately.

Stephen Kanipe, Aspen’s chief building official, said the city and Aspen fire officials are working with carbon monoxide manufacturers to supply detectors in bulk – as many as 10,000 at a time.

They will be sold at about $30 a piece and given to those who can’t afford one, Kanipe said.

Budget savings in city departments, as well as the fire department and individual donations, will help fund the giveaway program, he added.

“The city is prepared to be certain that no household has to do without one because of cost,” Kanipe said.
