Power in New York
New York's outages come from three very different New Yorks. Upstate it's ice: the North Country ice storm of January 1998 laid two to four inches of glaze across the St. Lawrence Valley, brought down thousands of utility poles, and left the Adirondack borderland counties dark for more than two weeks. On the coast it's tropical: Superstorm Sandy in October 2012 knocked out roughly 90% of the Long Island Power Authority's 1.1 million customers and left more than two million New Yorkers without power statewide. In between, summer heat and winter nor'easters lean on an aging grid from the Hudson Valley to Buffalo. A whole-home standby generator starts on its own within seconds and keeps the heat, well pump, sump pump, refrigerator, and medical equipment running until the utility restores the line.
Generator permits & codes in New York
- Who issues permits
- Your local building department issues the permit and inspects the work, enforcing the New York State Uniform Fire Prevention and Building Code — every city, town, village, and county administers the Uniform Code within its jurisdiction. New York City is the exception: its own Department of Buildings enforces the NYC Construction Codes and NYC Electrical Code. The electrical work is licensed work, but New York has no statewide electrician's license. The NYC DOB licenses master and special electricians (homeowner electrical permits aren't available in the five boroughs), Nassau and Suffolk counties and many Long Island towns run their own licensing, and upstate cities such as Buffalo, Rochester, Syracuse, and Yonkers each license separately; the state itself only licenses alarm-system installers.
- Timeline
- Varies widely by jurisdiction. Outside New York City, most residential generator permits are issued over the counter or online without plan review, with a single electrical inspection (plus a mechanical/gas inspection where a gas line is run) once the work is complete. In New York City the work must be filed with the DOB by a licensed electrician and cannot be pulled by a homeowner, so expect a longer process.
- Code in force
- Outside New York City, the 2017 National Electrical Code, referenced by the 2020 New York State Uniform Fire Prevention and Building Code, which took effect May 12, 2020. New York City runs its own electrical code: the 2025 NYC Electrical Code (enacted by Local Law 128 of 2024), based on the 2020 NEC, took effect December 21, 2025 — so two different NEC editions are enforced within the state depending on which side of the city line the home sits.
- Major utilities
- Con Edison serves New York City and Westchester County; National Grid covers central, northern, and western upstate New York; NYSEG (New York State Electric & Gas) serves large, scattered stretches of upstate; Rochester Gas & Electric (RG&E) covers the nine-county Rochester area; Central Hudson serves the mid-Hudson Valley; Orange & Rockland serves Orange, Rockland, and Sullivan counties; and PSEG Long Island operates the Long Island Power Authority (LIPA) grid across Nassau, Suffolk, and the Rockaways. All of them warn that a generator tied into house wiring can backfeed the lines and endanger restoration crews — the safe connection is a transfer switch installed by a licensed electrician.
- Worth knowing
- New York's defining wrinkle is its licensing-and-code patchwork. There is no statewide electrician's license: New York City runs its own large regime through the DOB — master and special electricians, with no homeowner permits in the five boroughs — while Long Island's counties and towns and the upstate cities each license separately, with no reciprocity between them. And because New York City enforces its own Electrical Code on the 2020 NEC while the rest of the state is on the 2017 NEC through the Uniform Code, the exact edition applied to your generator depends on which jurisdiction you're in.
Common questions about whole house generators in New York
How much does a standby generator cost installed in New York?
For a typical New York home, budget roughly $9,000–$15,000 all-in for a
whole-house air-cooled standby unit (about 18–26 kW): the generator,
the automatic transfer switch, the pad, the fuel hookup, the electrical
work, and permits. An essentials-only unit (10–14 kW) runs about
$6,000–$9,000, and liquid-cooled units for large homes climb past
$20,000. Fuel drives the spread: New York City, Long Island, and the
lower Hudson Valley are dense with natural-gas service, but much of the
rural North Country, Southern Tier, and Adirondacks has no gas main, so
those installs run on propane or heating oil and cost more up front. In
the five boroughs, the job must be filed by a licensed NYC electrician,
which adds to labor.
Do I need a permit to install a generator in New York?
Yes. A standby generator install requires an electrical permit — and
usually a mechanical or gas permit — from your local building department,
which enforces the New York State Uniform Fire Prevention and Building
Code (or, inside the five boroughs, the NYC Construction Codes and the
NYC Electrical Code), followed by an inspection. The electrical work is
licensed work, but New York has no single statewide electrician's
license: the NYC Department of Buildings licenses master and special
electricians, Nassau and Suffolk counties and many Long Island towns run
their own licensing, and upstate cities like Buffalo, Rochester,
Syracuse, and Yonkers each license separately. A reputable installer
pulls the permits and schedules the inspection — treat an offer to skip
the permit as a red flag.
What size generator do I need in New York?
That comes down to a load calculation any good installer runs during
the site visit, and New York's loads pull from both seasons. Winter is
the hard case upstate: homes on a heat pump with electric-resistance
backup, or with a furnace whose blower and controls need power, pull hard
on a subzero Adirondack or Southern Tier night, and a private well —
common across rural upstate — loses water the moment the grid quits.
Downstate, summer air conditioning in the New York City and Long Island
humidity is a heavy, near-continuous draw whose compressor surge sets a
floor on capacity. Essentials only fits in 10–14 kW; a typical whole
house lands at 18–26 kW; a soft-start on the AC can keep the unit,
and the price, smaller.
Generac, Kohler, Cummins, or Briggs & Stratton — does the brand matter?
All four make reliable home standby units; the installer and the
service relationship afterward matter more than the badge. Generac has
the largest dealer network in New York, so parts and warranty techs are
easy to find from Long Island through the Hudson Valley to Buffalo;
Kohler and Cummins have strong dealers in the larger metros. A
factory-authorized dealer can perform warranty service on its own brand,
which is worth weighing when two brands otherwise look alike. Use the
brand pages here to see who installs and services each one near you.
How long does installation take?
The on-site work is usually one to two days once the unit is in hand:
set the pad, run the gas and electrical, mount the transfer switch, and
commission it. The calendar time is longer — a site visit and quote, then
permitting, then the inspection. In New York City the job has to be filed
with the Department of Buildings by a licensed electrician and can't be
pulled by a homeowner, which stretches the timeline further. After a
major storm every step slows, because every house on the block wants a
generator at once. Ordering ahead of storm season, rather than the week
after, is how you avoid competing for both the unit and the crew.
What maintenance does a standby generator need?
An annual service — oil and filter, spark plugs on schedule, a battery
check, and a load test — on top of the weekly self-test the unit runs on
its own. New York's cold upstate winters are hard on the starting
battery, and a Long Island or coastal Westchester install near salt water
wants a regular corrosion check on the enclosure and connections. The
point is to prove the unit works before the season it's needed, not
during it. Many installers listed here offer maintenance plans, and
several service brands they don't sell. Neglected maintenance is the most
common reason a generator fails to start when the grid finally goes
down.
