Smoke and Carbon Monoxide Detector Inspections

We have information on how to apply for a Smoke and Carbon Monoxide (CO) Detector Inspection through the Fire Prevention Portal.

Most residential property owners need to inspect their smoke and carbon monoxide alarm system before they can sell their property. Our general inspectors perform the inspections, and also review complaints about potential violations of the law. 

How to Apply

For best results, apply for your Smoke/CO Detector Inspection as soon as you sign your Purchase and Sale Agreement.

We require a minimum of 10 business days advance notice to schedule an appointment date. This does NOT include weekends or holidays. All requests are scheduled on a first-come, first-served basis. They are assigned based on the first available appointment date.

Please do not submit multiple requests for the same inspection. We do not perform afternoon inspections in Allston, Brighton or East Boston.

Payment is now online

Payment is due prior to the scheduling of an appointment. You will receive an automatic email when your application has been accepted for intake and available for payment.

If you do not receive a confirmation that your application has been accepted or (after payment) an email with your scheduled appointment date, check your SPAM folder. If the mail is not in your SPAM folder, contact us at smokedetector.bfd@boston.gov or call 617-343-3628.

You must now allow 48 hours advanced notice to reschedule. Cancellations must be 24 hours prior to inspection.
