Looking Ahead: Smoke Detector and Alarm Locations

Posted on August, 14 2018

Local Law 113 of 2018 went into effect on June 9th of this year.

The law modifies the location requirements of smoke alarms/detectors in R Occupancy buildings in relation to cooking appliances. These requirements don’t go into effect until 2021, but will apply to replacements of such alarms/detectors and may be beneficial to the owners of such properties to plan to move such devices now.

Generally, the requirement is that within a dwelling or sleeping unit, the smoke detector/alarm shall not be installed within a 20 foot radius along a horizontal flow path from a fixed cooking appliance. The distance can be reduced to a 10 foot radius if the alarm/detector is equipped with a means of alarm-silencing or uses photoelectric detection. The distance can be further reduced for photoelectric alarms/detectors to a 6 foot radius where the kitchen or cooking area and adjacent spaces are not clearly separated partitions or headers and where placing the alarm/detector 10 feet away would be prohibited by other parts of the code.

Below are the sections modified by LL 113 of 2018:

  • Administrative Code:
§ 28-312.8 Location of smoke alarms and smoke detectors.
On or after January 1, 2021, smoke alarms and smoke detectors installed or replaced in group R occupancies shall be installed in accordance with section 907.2.11.5 of the New York City building code.
