Upper Darby, PA Building Safety: Carbon Monoxide Detectors (2026)

3, Carbon Monoxide Alarms, into the adopted 2015 International Property Maintenance Code's fire protection systems chapter. 1 covers dwelling units: carbon monoxide alarms must be installed outside of bedrooms in any dwelling unit that has fuel-fired appliances installed, or that has an attached garage, since both are recognized CO sources. 2 extends the same logic to Group E occupancies, meaning schools: carbon monoxide alarms, or combination smoke/CO alarms, are required in any classroom that has fuel-fired appliances installed, that communicates with a space containing such equipment, or that is served by a fuel-fired forced air furnace.

A single exception applies across both subsections: a building with an existing CO detection system already in place does not have to add further alarms. The section sits alongside the Township's smoke alarm amendments at § 417-11(VV) and (WW), all inserted under the same 2021 ordinance (No. 3096) adopting the 2015 IPMC with local amendments at § 417-10. Enforcement runs through the Code Official, defined at § 417-11(O) as the Director of Licenses and Inspection, the Director of Administrative Services, and the Fire Chief.
