Have your interconnected alarms installed or inspected by a pro in NY, or choose the best smart model to install yourself.
The right smart smoke detector in New York should be UL 217 listed, easy to test and able to alert you even when you're away. In multi-story homes, interconnection between detectors is the single most important feature.
Under NFPA 72 and state and local codes, working UL 217 listed smoke alarms are required in every bedroom, outside each sleeping area, and on every level of every home in New York. Many states require 10-year sealed-battery alarms. After a fire without compliant alarms, your insurance claim can be jeopardized. In a rental, the landlord must provide and install the alarms.
New York is dominated by multi-unit housing: about 19 of every 20 homes are apartments, condos or co-ops. Ground-floor units, apartments near fire escapes, and buildings with shared lobbies see the bulk of break-ins, often through a forced unit door in under two minutes. The large share of pieds-à-terre and frequently empty units — especially in Manhattan — creates long stretches of vacancy that burglars learn to spot.
Housing type: Dense urban (apartments dominate)
Main residential neighborhoods: Upper East Side · Park Slope · Forest Hills · Riverdale · Bay Ridge · Astoria
For a multi-story home, a hardwired install or interconnected alarms (all alarms sound at once), having a professional in New York handle it guarantees correct placement, a code-compliant installation and a check of your electrical wiring. It's also the simplest way to bring a rental portfolio up to code or equip the home of someone with reduced mobility.

Smoke is the main danger in a fire. Carbon monoxide (CO) is an invisible, odorless gas produced by gas heaters, furnaces, fireplaces and generators — deadly in high concentrations. If you have a fuel-burning heating system in New York, install a combination smoke + CO alarm (like the Nest Protect or a UL 2034 listed CO alarm). In the kitchen, opt for a heat alarm that won't trigger on cooking smoke.
Only the First Alert Onelink is natively HomeKit-compatible. For Siri automations and the Home app, it's the one to get. Our pick: First Alert Onelink.
For maximum protection with voice alerts, automatic interconnection and sensor self-testing. Our pick: Google Nest Protect.
To cover multiple rooms affordably with wireless interconnection and a 10-year battery. Our pick: Kidde Firex (2- or 3-pack).
For smartphone alerts with no monthly fee and no separate hub — a great fit for homes in New York. Our pick: X-Sense Smart Smoke Alarm.
Test your alarms once a month and replace each unit after 10 years at most.
It's not required: a standalone alarm installs itself in 5 minutes. That said, bringing in a professional in New York is genuinely worthwhile for a multi-story home (interconnected alarms), a hardwired install, a rental portfolio that needs to meet code, or an occupant with reduced mobility. The pro also confirms correct placement (bedroom hallways, away from the kitchen) and the condition of the electrical wiring.
Code requires alarms in every bedroom, outside each sleeping area, and on every level per NFPA 72. In practice, install one in each main room (living room, bedrooms). For a multi-story house in New York, plan on at least one per level, preferably interconnected.
Yes. You should choose alarms that are UL 217 listed, in New York as everywhere in the US. This listing guarantees detection reliability and alarm loudness (≥ 85 dB). Every model in our comparison is UL 217 listed.
A smoke alarm has a maximum lifespan of 10 years, after which the sensors age. The expiration date is printed on the back of the unit. Models with a 10-year sealed battery (Kidde, X-Sense) are replaced whole at end of life; for a removable battery, change it every year.
NFPA guidance calls for a detector inside every bedroom, outside each sleeping area, and on every level of the home — including the basement.
They detect different dangers. Smoke alarms are essential everywhere; a carbon monoxide detector is required wherever there's a furnace, fireplace or any fuel-burning appliance. Combination units cover both.
Yes — choose a detector that is UL 217 listed. Connectivity never replaces certified fire detection.
Smoke detectors should be replaced every 10 years. The battery may be replaceable or sealed depending on the model.
