Standby Generators in Sag Harbor, NY
A whole-house standby generator sized for a typical Sag Harbor home runs $1,516–8,810 installed by national figures, with an 18–22 kilowatt unit fitting most houses by the manufacturer’s own sizing guidance. Where Sag Harbor falls under the Town of Southampton, the generator permit is a flat $200; the electrician we send you sizes the unit and files the permit.

A standby generator in Sag Harbor is bought for one specific scenario: a multi-day outage with nobody home to notice. That is a real event here, not a hypothetical one, and the electrician we put you in touch with sizes the unit to the house rather than selling the biggest one on the lot.
Generators in Sag Harbor: what's different here
Whaling-era captains' houses with panels upgraded generation after generation, waterfront houses on the coves running sump pumps that depend on the power staying on, and a village split between two towns for everything it doesn't handle itself.
Bay-side Sag Harbor properties often lean on a well pump and a sump pump that both stop the moment the power does, which is the specific risk a generator addresses for a house near the water.
The Village of Sag Harbor's Building Department names "Electric Work Applications" as their own permit type, distinct from plumbing, alongside building permits and sign permits — though the Village publishes no fee amount or inspector name for it. Sag Harbor sits roughly three-fifths in the Town of Southampton and two-fifths in the Town of East Hampton along Division Street, so which town's electrical rules apply beyond the village line depends on which side of that line the house is on.
Permits in Sag Harbor run through the Village of Sag Harbor Building Department inside the village — which issues "Electric Work Applications" as their own named permit type — and the Towns of East Hampton and Southampton beyond the village line; the electrician we put you in touch with handles the filing where one is required.

FAQ
Generators questions
How much does a standby generator cost in the Hamptons?
Generac, the manufacturer, sizes an 18–22 kilowatt unit as the "sweet spot" for a roughly 2,000-square-foot house, and its own 22 kilowatt unit lists at $6,309–7,369 before installation. Installed, a whole-house standby generator runs $1,516–8,810 nationally by one guide (average $5,160) — though two other guides say $1,540–8,740 and $5,505–10,245. Putting the unit price together with typical installation, a pad and a permit works out to roughly $8,900–13,900 all-in for a 22 kilowatt unit. The Town of Southampton charges a flat $200 generator permit. Two real East End electrical companies already sell standby generators as a standard service line.
Read the full answer →Do I need a permit for a generator, EV charger or outdoor lighting in Southampton?
Yes, all three are separately permitted electrical work under the Town of Southampton's own 2026 fee schedule: a generator is a flat $200, an EV charging station is $100 each, and outdoor or landscape/pool lighting is $200 — one code covers both landscape and pool-adjacent fixtures under a single filing. The standard electrical permit application has dedicated fields for a generator's size and fuel type and for the number of EV chargers being installed, and it requires the contractor's Suffolk County electrical license number. A roughly 3% credit-card surcharge applies to fees paid by card. Outside Southampton Town, the permit desk and the fee differ — the electrician we send you to your town knows which one applies and files it.
How does Water Mill Electric Co. work?
Tell us what's going on with the house — an emergency, a repair, a generator, an EV charger, lighting, a rewire, or new construction — and where it is. We put you in touch with one licensed, insured electrician who works your town and does that kind of work, and they call you back, typically the same day for a genuine emergency. From there it's their quote, their schedule, their warranty. It's free for homeowners; participating electricians pay us a referral fee for the introduction. We are not an electrical contractor, we don't sell equipment, generators, panels or solar, and we don't sell your details — the one company we send you to is the only one that gets your number. We cover 9 South Fork towns and 7 kinds of electrical work.
