Electrical Permits in Nassau and Suffolk: The Complete Guide

On Long Island, you need an electrical permit for:

• Any new circuit or sub-panel
• Panel upgrade or replacement
• Service entrance change (new mast, new meter pan, new drop)
• Generator install with automatic transfer switch
• EV charger install
• Solar interconnection
• Hot tub, pool, or pool pump circuit
• New or relocated outlets in wet locations (kitchen, bath, exterior, laundry)
• Outdoor lighting run from a new circuit
• Any work behind a wall that exposes wiring for inspection

What does NOT require a permit

• Swapping a like-for-like fixture (replacing a ceiling fan with a ceiling fan, a dimmer with a dimmer)
• Replacing a receptacle or switch on an existing circuit
• Replacing a bulb, obviously

If the work involves running new cable, adding a circuit, or touching the service, it needs a permit. If it is just swap-in-place, it does not.

Long Island uses third-party electrical inspection agencies instead of town electrical inspectors. The two big ones are:

New York Board of Fire Underwriters (NYBFU) — founded 1867, the oldest electrical inspection authority in the country. Used by most Nassau towns and a lot of Suffolk towns. Inspectors are typically older, experienced, and pragmatic. They want code compliance but they are not looking for a reason to fail you.

Commonwealth Electrical Inspection Service — smaller, newer agency. Used by parts of Suffolk and some Nassau villages. Inspectors are often more paperwork-strict. Turnaround is usually faster.

You do not choose between them. Each town has one or the other (sometimes both). The permit you pull specifies which agency handles the inspection.

Fees:

• NYBFU: $85-$250 for residential work depending on scope
• Commonwealth: $95-$275 for similar work

Inspection turnaround:

• NYBFU: 2-5 business days after you call for the inspection
• Commonwealth: 1-3 business days

Nassau electrical permits are pulled at the town building department. Nassau has three towns and two cities:

Town of Hempstead

The largest. Includes Hempstead, Levittown, Oceanside, Long Beach border, Garden City village, Rockville Centre village, etc. Permit portal is online. Standard residential electrical permit is $125-$225. Turnaround is 3-7 business days.

Hempstead inspectors via NYBFU are thorough. Bring good documentation of wire sizes, breaker sizes, and grounding.

Town of North Hempstead

Includes Manhasset, Great Neck, Port Washington, New Hyde Park. Smaller department, sometimes slower during summer. $150-$275. Turnaround 5-10 business days.

Town of Oyster Bay

Includes Syosset, Hicksville, Plainview, Massapequa, East Massapequa. Online portal is newer and more usable. $125-$225. Turnaround 3-7 business days.

City of Glen Cove and City of Long Beach

Separate city building departments. Long Beach has its own inspection authority (not NYBFU) and is stricter about fastener spec and grounding — a post-Sandy thing.

Incorporated villages

Nassau has 64 incorporated villages. Some (Garden City, Great Neck, Manhasset) handle their own permits instead of going through the town. Ask us at the walk-through — we know which are which.

Suffolk has 10 towns plus villages. Each town building department handles electrical permits differently.

Town of Babylon

Online portal. $175-$325. 7-12 business days. Post-Sandy coastal spec rules apply in South Shore areas.

Town of Brookhaven

The largest town by population. Permits $200-$375. Historically slow — plan on 10-18 business days. We pull so many Brookhaven permits that we know the counter staff by name.

Town of Huntington

$225-$400. 7-14 business days. Strict about documentation and load calculations.

Town of Islip

$175-$325. 7-14 business days. Includes Ronkonkoma, Bay Shore, Islip hamlet, West Islip.

Town of Smithtown

$200-$350. 7-12 business days. Includes Commack, Smithtown, Kings Park, St. James.

Town of Riverhead

$200-$350. 5-10 business days. Smaller volume, often faster than the western towns.

East End towns — Southampton, East Hampton, Southold, Shelter Island

These four have their own rules. Historic district reviews often add 4-8 weeks. East Hampton can require stamped electrical drawings for anything over a basic service change. Plan ahead.

Incorporated villages in Suffolk

Lindenhurst, Babylon village, Amityville village, Northport, Asharoken, and others have their own village building departments.

Step 1 — Scope the work (we handle this)

We write the permit application with a scope description, circuit list, and load calculation. The application lists the licensed electrician (us) as the responsible party. You sign as the homeowner.

Step 2 — Submit the permit

Most towns now have online portals. Some still require in-person submission at the counter. We have the paperwork ready on day one.

Step 3 — Pay the fee

Included in our quote. The town charges us, we do not pass a markup.

Step 4 — Wait for the permit to issue

3-18 business days depending on the town. We start scheduling the work during this window.

Step 5 — Do the work

We install the panel, circuit, or generator with the permit number posted on the jobsite.

Step 6 — Call for inspection

After we finish, we call NYBFU or Commonwealth. They come out within 2-5 business days and inspect.

Step 7 — Pass, or correct and re-inspect

90%+ of our inspections pass on first visit because we build to code. If something gets flagged, we correct it and call for a re-inspection (usually no extra fee if same day).

Step 8 — Certificate of Compliance

The inspection agency issues a Certificate of Compliance (sometimes called a "Letter of Satisfaction"). Keep this. Your next homeowner will want to see it at resale.

We find unpermitted electrical work on maybe 30% of the Long Island houses we walk for panel upgrades. The consequences:

1. Insurance denial if there is ever a fire. Carriers check for permits and certificates. No permit = no claim.
2. Title and resale issues. Buyer's attorney asks for the C of C. If it does not exist, the sale stalls while the current owner retroactively permits the work, which costs more than the original permit would have.
3. Municipal fines. Range from $250 to $5,000+ depending on the town and the nature of the work.
4. Forced rip-out and re-do. If the inspector discovers hidden unpermitted work during a different permit's inspection, they can require it to be exposed, corrected, and re-inspected at your expense.
5. Personal safety. The permit is also a quality check. Unpermitted work is uninspected work, and uninspected work is where most electrical fires start.

Getting retroactive permits

If you inherited unpermitted work from a previous owner, it can usually be retroactively permitted. We have done this many times. The process is: open up the walls enough for the inspector to see the work, pull the permit, have it inspected, close the walls back up. Cost depends on scope, typically $800-$3,500 for a few circuits.

Nassau County — requires a Home Improvement Contractor (HIC) license for residential work. Electrical-specific master license is not required at the state level (NY does not have a state electrical license) but Nassau issues an electrical endorsement.

Suffolk County — requires a Suffolk County Master Electrician license. Issued after a written exam, 7 years of documented experience, and ongoing continuing education. This is the real barrier to entry.

NYC, NYC Boroughs, Nassau villages, Suffolk villages — each has its own licensing requirements on top of the county.

We hold Nassau HIC and Suffolk Master Electrician, plus village licenses where required. Every permit we pull is in our name, not yours.

Never hire an "electrician" who asks you to pull the permit yourself. Homeowners can pull permits for work on their own primary residence in NY, but the contractor is then unlicensed for the work and you own 100% of the liability.

Pulling an electrical permit on Long Island is mildly annoying and takes 1-3 weeks, but it is the single most important protection you have that the work was done right. The fee is a rounding error in the total job cost. The Certificate of Compliance is valuable forever.

Any Long Island electrician who asks you to skip the permit to save money is telling you something about how they approach every other part of the job. That is a warning, not a deal.

We pull every permit on every job, as part of our standard quote. If you are evaluating multiple contractors, ask each one: "Is the permit in the quote?" and "Will you pull it in your own name?" The answers should be yes and yes.
