By Mario Bailey, verified against official sources
Quick answer
The Building Division's own Zoning Setbacks sheet states that decks 8 inches or less in height above grade in a conforming location do not require a building permit. Anything that rises higher than that needs one, and the Building Division FAQ lists decks and porches among the accessory structures that need a permit. Zoning Sec. 85-12.B says the same thing in the code's words, exempting decks, patios and walkways not above grade greater than eight inches at any point, constructed of any material, when accessory to one- and two-family dwellings and in a conforming location. Deck is also named in the town's list of residential permit types accepted through the online application.
Typical threshold: deck rising more than eight inches above grade at any point.

How to apply in Town of Brookhaven
A residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- A permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- A scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- A deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- A section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
Deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).
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.

- Where do you apply for a deck permit in Town of Brookhaven?
- You can apply through the Town of Brookhaven permit portal or contact the Town of Brookhaven Division of Building (Building Division), Department of Planning, Environment and Land Management directly. The links are listed on this page.
- Can a homeowner pull a deck 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. Confirm how Town of Brookhaven applies this before you apply.
