REMODELING PERMITS
TOWN OF BROOKHAVEN, NY

Kitchen & Bathroom Permits in the Town of Brookhaven

Why Does the Permit Answer Change From Town to Town?

Because New York State wrote it that way. 19 NYCRR 1203.3(a)(1) requires every authority having jurisdiction to require building permits for work that must conform to the Codes. It then lets localities exempt eight categories, two of which matter here: “painting, wallpapering, tiling, carpeting, or other similar finish work,” and “repairs, provided that the work does not have an impact on fire and life safety.” The State mandates the permit for regulated work and merely allows the exemption for cosmetic work. Each of Suffolk County's ten town departments decides whether to take that option, and how much of its decision to write down.

What Triggers a Brookhaven Building Permit?

The Town states the rule in a single sentence: “A building permit is required for new homes, additions, alterations, manufactured homes, and accessory structures.” Its permits page lists “Alterations or Repairs” among the types it issues. The word carrying the weight for remodelers is alterations, and Brookhaven publishes no definition of it specific to kitchens or bathrooms.

That absence has to be stated rather than filled. Brookhaven publishes no cosmetic-work exemption list and no kitchen or bathroom guidance. Neighbouring Islip publishes a permit-trigger sheet naming paint, wallpaper, tile, carpet and cabinets as finish work needing no permit. Brookhaven publishes nothing equivalent, and we are not going to write an assumption down as though the Town had said it. If your scope is finishes only, describe it to the Building Division and take the answer from the department that will inspect the job.

The Minor-Plumbing Exemption, and the Chapter Almost Everyone Cites Wrong

Brookhaven does publish one exemption that matters enormously to bathroom work, and it is filed in a place nobody looks. It is not in the building chapter. It is in Chapter 85, the zoning chapter, at § 85-12(B), and it reads: “A building permit shall not be required for minor repairs to existing plumbing systems.” The same subsection exempts sheds and gazebos of 144 square feet or less, trellises, pergolas and arbors at the same size, and decks, patios and walkways not more than eight inches above grade.

The Town's own FAQ directs readers to Chapter 16 for this material. The exemption text sits in Chapter 85. If you are reading a competitor's permit guide that cites Chapter 16 for Brookhaven plumbing, it is pointing you at the wrong chapter, and you will not find the sentence there. Getting the citation right is the difference between a homeowner who can read the rule and one who gives up.

Now the harder part. “Minor repairs” is not defined anywhere in the Brookhaven code. There is no published test, no dollar threshold, no fixture count and no list of examples separating a minor repair to an existing system from a modification of that system. Replacing a leaking angle stop is plainly a repair. Moving a toilet three feet, which means new soil, waste and vent piping, is not a repair to the existing system. Between those poles sits most of what happens in a bathroom renovation.

So make the call a phone call. Describe the scope to the Building Division at 631-451-8696, 1 Independence Hill, Farmingville, NY 11738, Monday to Friday, 9:00 a.m. to 4:15 p.m., and let the department that will inspect the work tell you which side of the line it sits on. A contractor who is certain where an undefined term begins is describing his confidence, not the code.

Brookhaven Permit Triggers, Kitchen and Bathroom Side by Side

What Does Brookhaven Want in the Application Package?

This is where Brookhaven is genuinely well documented. The requirements below come from the Building Permit Application dated 03/23/2026, the current form as of July 2026.

Two contrasts are worth carrying with you. Brookhaven asks for two surveys; the Town of Huntington asks for three. Surveys come from a licensed surveyor and are not free, so the count matters, and so does the requirement that they be dated within a year — the survey in your closing folder from six years ago does not qualify. Second, Brookhaven requires a disability benefits form and Huntington's published alteration package does not. Insurance paperwork is the most common reason a complete-looking application gets sent back on Long Island, and Brookhaven names the acceptable forms so you can ask your carrier for the right one.

The Planning Department step is real and worth scheduling around. Brookhaven's checklist calls for Planning Department approval evidenced by an original stamped survey, so the survey travels through a second department before your building permit is complete. Whether a fee attaches to that review we cannot tell you: no such fee appears in Brookhaven's Planning fee schedule revised 1-16-26.

Is There a Separate Brookhaven Plumbing Permit?

Brookhaven's Forms page lists a “Plumbing Worksheet” rather than a plumbing permit application. The distinction matters: a worksheet is completed inside another application, while a permit application is a filing of its own with its own fee and number. The absence of a standalone plumbing form indicates that plumbing in Brookhaven is documented within the building permit rather than permitted separately.

We mark that likely rather than confirmed, because an absence is weaker evidence than a statement. Ask the Building Division at 631-451-8696 whether your plumbing scope is filed on the building permit or separately, and ask before your plumber is standing in the room.

On who may do the work: we found no Town of Brookhaven contractor, plumber or electrician licence. That is a real contrast with Islip, which requires a Town-licensed master plumber to perform the work and schedule every inspection, and with Huntington, which licenses master and limited plumbers itself. Treat that finding as likely rather than proven, and confirm it if it is load-bearing for your project.

Our own carpenters and project managers run your job start to finish. Electrical and plumbing are performed by licensed Nassau and Suffolk trade contractors we've worked with for years — we schedule them, we coordinate the inspections, and we're accountable for the result. Greene Group Construction holds Suffolk County HIC #HI-72958 and Nassau County HIC #EF-65498. We hold no town-level trade licence in Brookhaven or anywhere else.

Electrical Work and Electrical Inspection in Brookhaven

Brookhaven's code is direct: “It shall be unlawful for any person to install or cause to be installed or to alter or repair electrical wiring for light, heat or power until an application for inspection has been filed.” The filing comes before the work. The Town accepts a certificate from “The New York Board of Fire Underwriters or another approved electrical inspection service.”

The New York Board of Fire Underwriters is named here because Brookhaven's own code names it. The Town publishes a roster of the other approved services, but that document was not reachable when we looked, so we name no agency from it. Call 631-451-8696 and ask for the current list before an electrician picks an inspector. That certificate is not a formality: an original electrical inspector's certificate is a hard requirement for your certificate of occupancy.

What Does a Brookhaven Building Permit Cost?

The Town of Brookhaven does not publish a Building Division fee schedule online. That is the whole answer, and it is worth stating flatly because the alternative is a guess dressed up as research. Brookhaven's cost FAQ points readers toward a fee schedule document that could not be located. Fee schedules are published for the Planning Department, the Highway Department, the Board of Zoning Appeals and Fire Prevention, which makes the Building Division gap conspicuous. As of July 2026 the only reliable way to learn what your permit costs is to call 631-451-8696.

One more thing you will see elsewhere and will not see here. Secondary permit guides circulate a specific Planning Division review fee for one- and two-family building permits. We could not verify any such amount, and none appears in Brookhaven's Planning fee schedule revised 1-16-26. The Planning review step is verified. The amount is not, so we print no number for it.

Brookhaven also publishes an “Accelerated Plan Review or Inspection” form. Neither its fee nor the timeframe it promises is published. A paid expedite option whose price and turnaround are both unstated is a genuinely unusual thing to find on a municipal forms page, and it is worth asking about directly if your schedule is tight.

How Long Does a Brookhaven Permit Last, and How Long Does It Take?

The Town states it cleanly: “A building permit is valid for one year from the date it was issued. A demolition permit is valid for 90 days.” A Building Permit Renewal form exists. What the renewal costs, and how long a renewed permit runs, are not published. One year is comfortable for a bathroom and tight for a kitchen waiting on custom cabinetry, so file when the scope is settled.

Filing and tracking happen through CIVICS, described by the Town as its “Online Permitting, Licensing, and Registration System.” Brookhaven also runs a separate status lookup requiring no login, useful for checking a permit filed under your contractor's account. Whether inspections can be scheduled inside CIVICS is not stated.

What Brookhaven Requires for a Certificate of Occupancy

Here Brookhaven flips from thin to unusually thorough. Its certificate of occupancy requirements, published 10-02-25, are more specific than most towns manage. Read them at the start of the project, because several cannot be arranged retroactively.

Two items deserve emphasis. The electrical certificate must be an original showing the rough inspection date, so that inspection has to have happened and been documented before the walls closed. The Planning and Health certifications must be final originals, copies expressly not accepted.

There is a real concession for interior-only work. Zoning Code § 85-15 allows the Chief Building Inspector to waive the final survey “for certain interior alterations.” A bathroom gut inside existing walls, or a kitchen refit that changes no footprint, is the kind of scope that language contemplates. It is discretionary and case by case, so ask early rather than assume, but a waived final survey removes a line item and a delay from the end of the job.

Mastic Beach: The Village That No Longer Exists

A Mastic Beach homeowner files with the Town of Brookhaven. The Village of Mastic Beach voted to dissolve in November 2016, and the Town of Brookhaven resumed jurisdiction over the area. There is no village building department to file with, no village fee schedule and no village code layered on top of the Town's.

We mark the effective date as commonly reported rather than State-confirmed, because the vote and the date the dissolution took legal effect come from secondary sources we could not check against a State record. The direction of the answer is not in doubt; the precise date is what we are hedging.

This matters because permit guides age badly. Older directories and expediter sites still list Mastic Beach as an incorporated village with its own building department. If you are in Mastic Beach, start at 1 Independence Hill, Farmingville, NY 11738, 631-451-8696.

The Eight Incorporated Villages Inside Brookhaven

Suffolk County is made up of ten town building departments and 32 incorporated villages. Eight sit inside the Town of Brookhaven: Belle Terre, Bellport, Lake Grove, Old Field, Patchogue, Poquott, Port Jefferson and Shoreham. Each permits separately, with its own application, its own fee schedule and potentially its own trade licence requirements. Everything on this page describes the Town's rules for the parts of the Town the Town permits, and none of it describes those eight villages.

Bellport runs its own building department at 29 Bellport Lane, 631-286-0327. Patchogue, Port Jefferson and Belle Terre each publish their own building pages and codes. The practical test is your property tax bill: village residents are billed a village tax as a separate line, and residents of the Town's unincorporated areas are not.

Can a Kitchen or Bathroom Remodel Raise Your Brookhaven Property Taxes?

An improvement can raise an assessment, and New York's Home Improvement Exemption under RPTL § 421-f softens that: 100% of the increase is exempt in year one, declining 12.5 percentage points a year through year eight. The improvement must exceed $3,000, the greater portion of the building by square footage must be at least five years old, ordinary maintenance does not qualify, and the exemption is opt-in by locality. The statutory cap is $80,000.

Brookhaven has adopted it: Local Law No. 1 of 1999, effective January 22, 1999, at the $80,000 cap, minimum improvement more than $3,000. The filing deadline is March 1 and the form is RP-421f. Confirm eligibility with the Brookhaven Town Assessor. This is general information, not tax, legal or code advice.

What Does the Work Itself Cost, and Who Handles It?

Permit fees are a small line inside a much larger number, and in Brookhaven they are a line you cannot look up. Our published planning ranges run from about $12,000 for a surface bathroom refresh to $250,000 and above for high-end custom kitchen work; the detail sits in our Long Island kitchen remodel cost guide and our bathroom remodel cost guide. For the full service picture, start at kitchen remodeling or bathroom remodeling. For how Brookhaven sits alongside the other nine Suffolk departments and where the county Health Department enters, read bathroom remodeling in Suffolk County and kitchen remodeling in Suffolk County.

Permit questions get urgent in one scenario. When a bathroom or kitchen is rebuilt after a failed supply line or a leaking shower pan, the damage rarely stops at the finishes, and the subfloor, joists and ceiling below need assessing before anyone talks about tile. Greene Group Construction runs water damage restoration and insurance claims support as real service lines, so documentation, mitigation and the rebuild sit under one contract. Structural work runs through our general contracting division, and debris leaves with our own junk removal and cleanout crews.

Town of Brookhaven Remodeling Permit FAQ

Do I need a permit to remodel a bathroom in Brookhaven?
It depends on the scope, and Brookhaven publishes less guidance than some of its neighbours. The Town states that a building permit is required for new homes, additions, alterations, manufactured homes, and accessory structures. Zoning Code section 85-12(B) provides that a building permit shall not be required for minor repairs to existing plumbing systems. The code does not define minor repairs, and Brookhaven publishes no cosmetic-work exemption list and no bathroom-specific guidance. Call the Building Division at 631-451-8696 with your actual scope before you assume either answer.

Do I need a permit to remodel a kitchen in Brookhaven?
Brookhaven publishes no list of exempt cosmetic work and no kitchen guidance, so the general rule is the one to read. A building permit is required for new homes, additions, alterations, manufactured homes, and accessory structures, and the Town's permits page lists Alterations or Repairs as a permit type. Removing a wall between a kitchen and a dining room, adding fixtures, or relocating the sink are the scopes most likely to be treated as alterations. Confirm your scope with the Building Division at 631-451-8696.

Does the Town of Brookhaven require a separate plumbing permit?
Brookhaven's Forms page lists a Plumbing Worksheet rather than a standalone plumbing permit application. The absence of a separate form indicates that plumbing is documented inside the building permit rather than permitted on its own, which would put Brookhaven in contrast with towns that run a separate plumbing filing. We are treating that as likely rather than confirmed, because it rests on the absence of a form rather than on published language. Confirm with the Building Division at 631-451-8696.

What does a Town of Brookhaven building permit cost for a kitchen or bathroom?
The Town of Brookhaven does not publish a Building Division fee schedule online in any form we could locate as of July 2026. Brookhaven does publish fee schedules for its Planning Department, Highway Department, Board of Zoning Appeals and Fire Prevention, which makes the Building Division gap conspicuous. The Town's own cost FAQ points to a fee schedule document that could not be located. Call 631-451-8696 for current amounts. Any figure quoted to you without a source is a guess.

What does Brookhaven want in a building permit application package?
From the Building Permit Application dated 03/23/2026: two original to-scale surveys signed and stamped by a surveyor and dated within one year; three sets of plans plus a digital PDF copy if available; the owner's signature sworn before a notary; workers' compensation form C-105.2, U-26.3, GSI-105.2, SI-12 or CE-200; disability form CE-200, DB-120.1 or DB-155; the recorded deed if the property has been owned less than a year; and Suffolk County Health Department approval. Historic, wetlands and homeowners association approvals apply where relevant.

I live in Mastic Beach. Do I file with the village or with the Town of Brookhaven?
A Mastic Beach homeowner files with the Town of Brookhaven. The Village of Mastic Beach voted to dissolve in November 2016 and no longer exists as an incorporated village, and the Town of Brookhaven resumed jurisdiction over the area. The effective date of the dissolution is commonly reported but we have not confirmed it against a State record. Older permit guides and expediter directories still list Mastic Beach as a village with its own building department. File with Brookhaven at 1 Independence Hill, Farmingville, or call 631-451-8696.

What does Brookhaven require for a certificate of occupancy?
Brookhaven's published requirements, dated 10-02-25, are unusually detailed. They include a final survey by a licensed surveyor showing the Suffolk County Tax Map Number; an original certificate issued by a certified electrical inspector showing rough and final inspection dates and the permit number; an original Certificate of Assessment from the Tax Assessor; final original certification from the Suffolk County Health Department; final original certification from the Planning Department with no copies accepted; a Debris Affidavit; a Disclosure Affidavit; a HERS Rating Certificate where applicable; possible gas supply line test certification; and one set of photographs of all sides of all structures.

How long is a Brookhaven building permit good for, and how long does it take to get?
The Town of Brookhaven states that a building permit is valid for one year from the date it was issued, and that a demolition permit is valid for 90 days. A Building Permit Renewal form exists; the renewal fee and the length of a renewal term are not published. Brookhaven does not publish a permit turnaround time, and no Long Island jurisdiction we examined does. A contractor quoting you a guaranteed number of days is inventing it.
