New York City Class A and Class B multiple dwellings need compliant natural gas alarms installed by January 1, 2027. One or more alarms may be required in each dwelling unit, because every fuel-gas-burning appliance has to be covered by an alarm in the same room and within the required placement distance. If you are responsible for a portfolio rather than a home, that is a procurement and logistics problem with a fixed end date. ChesGuard supplies the CG-GD1 in volume with pricing, documentation and rollout support built around that deadline. Tell us the unit count and the timeframe and we will come back with a quote.
Who This Page Is For
- Property managers and managing agents running multi building portfolios
- Building owners and landlords with Class A or Class B multiple dwellings
- Co-op and condo boards planning a building wide rollout
- Superintendents and maintenance teams who will do the installation in house
- Housing providers, developers and general contractors specifying for new occupancy. Note that battery-powered alarms may be used in qualifying existing buildings, and different power requirements may apply to buildings completed on or after January 1, 2027, so confirm the power requirement before you specify.
Why A Battery Alarm Collapses Your Installation Cost
Under 1 RCNY 908-02(g), a line powered natural gas alarm has to be installed by a New York City licensed electrical contractor and requires permits. In qualifying existing buildings, a battery powered alarm may be installed by the owner, by maintenance personnel or by the occupant. No electrician, no permit, no electrical work. Different power requirements may apply to buildings completed on or after January 1, 2027.
On a portfolio of any size this is where the money is. A hardwired rollout means a licensed contractor, permit filings, a coordinated unit access schedule that has to fit somebody else's calendar, and a per unit labor cost that frequently runs higher than the device itself. A battery rollout means a cordless drill, the supplied mounting hardware, and your own superintendent working through a floor at a time. The compliance outcome under the rule is identical. The difference is measured in months of scheduling and in labor you do not have to buy.
What We Supply
- Volume pricing scaled to the unit count, quoted per order rather than published, because a 40 unit building and a 4,000 unit portfolio are not the same job
- Delivery scheduling agreed with you at the time of quoting, so stock arrives in line with your installation plan
- Compliance documentation including the Intertek Certificate of Compliance and the manufacturer's stated useful life, which owners are required to record
- Installation material for your maintenance team, including the placement rules and the test procedure in a form you can hand to staff
- Bilingual manuals in English and Spanish, in the box on every unit
- Replacement cycle planning based on a battery designed to last approximately 10 years from activation and an alarm service life of approximately 10 years from installation, so the next cycle is scheduled rather than discovered

How Many Alarms Will You Need?
Count appliances and rooms rather than units. A studio with a range and a gas water heater in the same room is usually one alarm. A two bedroom apartment with a range in the kitchen and a gas dryer in a separate laundry room is two, because no single position covers both rooms within the required 3 to 10 feet. If you are not sure, send us a typical floor plan with the quote request and we will work it through with you.
