Residential Smoke Detector, Carbon Monoxide Detector

& Fire Extinguisher Rules and Regulations


Fire safety notes to be aware of prior to your C of C inspection

As of January 1, 2019 in accordance with the Uniform Fire Code there are new regulations regarding smoke detectors. Please be advised that if you have battery operated smoke detectors they must be a ten year sealed battery – powered single station smoke alarm and shall be listed in accordance with ANSI/UL 217. However, A/C – powered single or multiple – station smoke alarms installed as part of the original construction or rehabilitation project shall not be replaced with battery powered smoke alarms. (Please read all of the information attached to your application package carefully as some of the rules have changed which may affect the outcome of your inspection.)

  • Please be advised that if you have a battery operated smoke detector you will be required to remove the smoke detector from the ceiling so that it can be inspected by the Code Enforcement Officer so that he can determine if the correct detector was installed. Therefore, please be prepared to have a ladder available the day your inspection is scheduled. It shall be the owners / owner’s representatives’ responsibility to remove and re-install the smoke detector at the time of the inspection. Please review all of the requirements for smoke detectors and carbon monoxide detectors on the documents provided to you as part of your application and noted here for your convenience.
  • Please review the requirements for fire extinguishers as there are several regulations regarding size and installation that must be followed.
