Rewiring an older Hamptons house, additions and new-construction electrical
Whole-house rewiring costs range enormously depending which guide you read: one puts the average at $1,567 ($603–2,596), a second figure from the very same publisher says $6–10 per square foot ($12,000–20,000 total) — roughly double the first page’s rate — and two more guides say $7,191–13,384 and $1,406, respectively. New York adopted the 2023 National Electrical Code statewide effective December 31, 2025, enforced, per Southampton’s own fee schedule, "at both the town and village levels."

What this covers
A whole-house rewire in an older home, the electrical portion of an addition or renovation, and new-construction wiring from the ground up. All three are priced and permitted the same way: by the scope of the job and the square footage involved, filed through whichever municipality has jurisdiction over the property.
What it costs — four figures, not reconciled
| Source | Figure |
|---|---|
| One national guide's dedicated rewiring page | Average $1,567 (range $603–2,596); $3–5 per sq ft |
| The same publisher's separate panel-upgrade page | $6–10 per sq ft ($12,000–20,000 total) — roughly double the rate above |
| A second national guide | $7,191–13,384 |
| A third source (attributing the figure to the first guide, but not matching either of its pages) | $1,406 average ($555–2,286) |
This is an unusually wide spread even by this trade's standards, including two figures from the same publisher on the same day disagreeing by roughly 2x on the per-square-foot rate. We show all four rather than pick one; a real quote from a licensed electrician who has seen the house is the only number that actually applies to your project.
The code
New York adopted the 2023 edition of the National Electrical Code statewide, effective December 31, 2025. Southampton Town's own fee schedule states plainly that the code is enforced "at both the town and village levels." (New York City runs a different, older edition with its own amendments — not relevant to the South Fork.) A rewire, addition or new-construction job in East Hampton Town's unincorporated hamlets goes through the Town's Building Department, which asks for two sets of quarter-inch plans, licensed-contractor documentation, workers' compensation proof and a survey; Southampton Town's process is documented in detail in our panel-upgrade page.
What old wiring means for insurance — and what we won't claim
Two wiring types draw specific insurance scrutiny: aluminum wiring, which a 2011 federal safety finding linked to a 55-times-higher risk of a fire-hazard connection than copper, and which many standard insurers restrict or decline without repairs; and knob-and-tube wiring, treated more harshly still, which insurers commonly decline outright or condition on a full rewire. What we will not do is tell you what percentage of Hamptons homes have either — no source ties a home's construction year to what wiring is actually behind its walls today, since decades of renovation and ownership turnover mean plenty of older homes have been fully rewired and plenty of newer additions have only patched into what was already there. An inspection is the only way to know, and it is the first step of any rewire, addition or new-construction quote.

FAQ
Common questions
Will old wiring affect my homeowners insurance?
It can, depending on the type, not simply the age of the house. Aluminum wiring, common in some homes built in the 1960s and 70s, is widely restricted by standard insurers — a 2011 federal safety finding put it at 55 times more likely than copper to reach a fire-hazard connection — and many carriers require an inspection or repairs before covering a home that has it. Knob-and-tube wiring, older still, is treated more harshly: insurers commonly decline it outright or require a full rewire first. What we could not find, and won't claim, is any figure for what share of Hamptons homes still have either — a house's construction year alone doesn't tell you what's actually behind the wall, since decades of renovation change it. An inspection is the only way to know; ask your insurer what they require once you do.
Is there a statewide electrician license in New York?
No. New York State's own Department of State licensing page lists every state-issued license type — notary, real estate, cosmetology and more — and none of them is an electrician or electrical-contractor license. Electrical work is licensed at the county and municipal level instead. On the South Fork, the clearest evidence that Suffolk County licenses electrical contractors directly is the Town of Southampton's own permit application, which requires a contractor's Suffolk County License number and its expiration date before a job can be filed. We could not locate a public way to look up or verify that number ourselves — the county documents that would spell out the exam, fee and renewal terms returned an access error every time we tried — so we rely on the town's own permit-filing check instead.
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.
