Good afternoon,

Beginning July 1, 2022, carbon monoxide detectors will be required for all new Mechanical Change-Out permits, except for projects involving only electric-powered equipment.

Under the 2021 International Residential Code, the new requirements apply to installation, alteration or repair of all fuel-fired mechanical systems. Inspectors from the City of Austin Development Services Department will check for this safety equipment when inspecting projects permitted on or after July 1. Because this is a critical life and safety issue, there are no exemptions or alternatives to compliance with this requirement.

The specific type of equipment used can be part of a combined system for detecting smoke and carbon monoxide. However, while carbon monoxide equipment must be wired into the home and include a battery backup for new construction, battery-powered carbon monoxide detectors or alarms are allowed under the Code requirements for Mechanical Change Outs.

If you have questions about this new requirement prior to inspection, please contact the DSD Building Inspections team for assistance.
