Quick answer
These rows cover the unincorporated Town of Brookhaven only. Eight incorporated villages inside the town, including Patchogue, Port Jefferson, Bellport and Lake Grove, run their own building departments, and Brookhaven's rules do not apply inside them. On fences, the town's own Fence Code handout sets a general four-foot height limit, allows a six-foot fence in the rear yard where a residence has been erected, and states that a six-foot fence in a secondary front yard on a corner or through lot is a structure requiring a building permit. The town's fence diagram puts it plainly: a six-foot fence on the property line needs a building permit, four feet does not. Fence is listed by name among the residential permit types accepted through the online application.
Typical threshold: fence taller than four feet in a secondary front yard on a corner lot or through lot.

How to apply in Town of Brookhaven
Most residential fences fall under the model code's 7-foot building-permit exemption, so the real approval step is a lightweight zoning or land-use permit built around a simple site plan showing the fence's location, height, and material, checked against setbacks and any corner-lot sight-triangle rule. A fence that will serve as a required swimming-pool barrier is the exception, since barrier fences carry life-safety requirements of their own.
What most fence permit applications include:
- A fence 7 feet or under is exempt from the model code's building permit, the same threshold the IRC uses for other small projects (IRC 2021 R105.2).
- That exemption only removes the building-code permit. It does not authorize skipping a jurisdiction's own zoning approval, which is why an exempt fence can still need its own land-use or zoning permit rather than a building permit (IRC 2021 R105.2).
- Whatever your jurisdiction calls that approval, the application centers on a basic site plan: a drawing of the property showing the fence's location, height, and material, and how it relates to the property lines (common local zoning practice).
- The same plan is checked against required setbacks and, on corner lots or near intersections, a sight-triangle rule that caps fence height so it does not block sightlines for drivers (common local zoning practice).
- A fence that will serve as a required swimming-pool barrier is handled as life-safety work rather than the light zoning process, and at least one state's adopted residential code requires a building permit for barrier fences regardless of the general fence exemption (Oregon Residential Specialty Code 2021, R101.2.2).

Inspections and closing out your permit
Inspection follows the permit: a fence that never needed one gets no inspection at all under the model code, and a permitted fence typically gets a single final check rather than the staged inspections used for a house. The exception is a fence serving as a swimming-pool barrier, which gets its own dedicated barrier inspection covering height, gaps, and gate hardware.
- Inspection duty attaches only to work for which a permit is required, so a fence that qualified for the permit exemption carries no inspection obligation under the model code (IRC 2021 R109.1).
- Where a fence permit was issued, the process skips the staged foundation, frame, and rough-in inspections used for buildings and goes straight to one final inspection once the fence is finished (IRC 2021 R109.1.6).
- That single check is typically a zoning compliance inspection rather than a structural review, confirming the fence matches the approved height and site plan (common local practice).
- A fence built as a swimming-pool barrier breaks that light-touch pattern: it is separately inspected for barrier compliance, commonly required before the pool itself can be signed off (ISPSC 305; local pool-barrier inspection programs).
- That barrier inspection checks dimensional rules from the swimming pool and spa code rather than ordinary fence rules, including the minimum 48 inch barrier height and limits on openings and gaps a young child could pass through (ISPSC 305).
- Gate hardware is inspected too: a self-closing, self-latching gate is part of the barrier requirement, since an unlatched gate defeats the fence's purpose as a barrier (ISPSC 305).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Town of Brookhaven permit portal or by phone at 631-451-6333.

- Can a homeowner pull a fence permit themselves in Town of Brookhaven?
- Under New York law (Inside New York City: NYC Admin. Code 28-104.1, 28-105.1, 28-105.4, 28-105.5.1, 28-401.3 (definition of "general contractor"). Outside New York City: N.Y. Exec. Law 381(2); 19 NYCRR 1203.3(a)(1).): New York State sets no owner-builder rule at all outside New York City. Executive Law 381(2) puts administration and enforcement in the hands of each local government, and 19 NYCRR 1203.3(a)(1) only requires each authority having jurisdiction to make building permits mandatory for work that must conform to the codes, leaving who may apply to local law. The state licenses no general contractors and imposes no owner-builder affidavit, disclosure form or post-permit sale restriction of the kind Florida uses, so whether a homeowner may pull the permit is a question for the specific city, town, village or county. New York City is the genuine outlier. Administrative Code 28-105.1 makes the work itself unlawful without a written permit, and Administrative Code 28-104.1 bars the department from issuing that permit until it approves the required construction documents, which must be prepared by or under the supervision of a registered design professional, meaning a licensed architect or engineer, as required by the code. A homeowner therefore cannot self-prepare and file the plans for permit-requiring work in New York City even though Administrative Code 28-105.5.1 defines the permit applicant as the person who performs the work or retains a subcontractor, and even though the general contractor registration definition in Administrative Code 28-401.3 expressly excludes an individual who constructs a residential structure of no more than three dwelling units for his or her own occupancy. Note that Administrative Code 28-105.4 exempts minor alterations and ordinary repairs from the permit requirement entirely, so the design professional bottleneck applies only to work that needs a permit in the first place.
