Deck Builders Near Me in Brooklyn, NY? Build Your Own Deck With an A-DIY Kit

You can do either. When you interview Brooklyn deck contractors, ask about recent brownstone and rowhouse projects, who handles the Department of Buildings filing and, in a historic district, Landmarks approval. If you’d rather build it yourself, A-DIY delivers professionally engineered deck kits to Brooklyn homes, and a drill is the only tool you need to assemble one after you confirm what the city requires for your lot.

It depends on size, materials, how hard the yard is to reach and the professional fees tied to permits. A-DIY kits start at $3,699 for a 6x12 wood deck, and a 12x12 is $4,899 in pressure-treated wood or $5,700 in composite. Compact sizes up to 8x20 are popular for narrow Brooklyn yards, and every kit includes framing, decking, footings and hardware.

With A-DIY, a 12x12 deck kit is $4,899 in pressure-treated wood or $5,700 in composite. A 12x16 composite kit is $6,600; the closest wood size is 12x18 at $5,969. A 16x20 kit is $7,600 in wood or $10,199 in composite. Framing, decking, footings and hardware are included.

Homeowners who use an A-DIY kit typically spend 30–50% less than hiring a contractor. You can split the cost into 0% payments over up to 8 months or build now and pay later with Affirm, Klarna or Shop Pay, subject to approval. A-DIY Reserve holds today’s price with a $250 non-refundable deposit while you sort out approvals.

Usually, yes. Brooklyn is one of the five boroughs, so decks are governed by the NYC Construction Codes and permitted by the NYC Department of Buildings. DOB’s guidance says plans must be approved and a permit issued before deck construction begins, with the design prepared by a licensed engineer or architect. The 200 sq ft freestanding-deck exemption cited elsewhere in New York State should not be assumed to apply. Check with DOB before you order.

Many customers use their A-DIY decks for hot tubs and saunas. Applicable configurations are engineered to hold up to 15,000 lbs when properly assembled and supported, but tub weight, placement and wiring vary, so talk to a deck specialist before you order and check local electrical and permit rules.

Often. Brooklyn has many designated historic districts, from Brooklyn Heights and Park Slope to Fort Greene and Crown Heights North. Exterior work on a landmarked building or within a historic district, including rear-yard decks, generally needs a permit from the NYC Landmarks Preservation Commission in addition to DOB approvals. Check the city’s landmarks map for your address before you plan the deck.

Under the NYC Building Code, permanent foundations generally must be protected from frost, typically by extending at least 4 feet below the adjacent grade. A-DIY kits are freestanding ground-level decks that rest on the included Tuff Block footings 15–17 inches off the ground. Ask DOB or your design professional whether that suits your yard, and check the deck for level each spring.

In many cases. Compact kits from 6x12 to 8x20 are sized for narrow lots, and a 12x12 suits a wider yard. In a required rear yard, a deck generally can’t extend more than 8 feet from the building, and combustible decks need to stay 3 feet from property lines, so measure before you choose a size. A-DIY kits are built at ground level, not on roofs or parlor-floor balconies.

Pressure-treated wood kits come in 15 sizes: Standard 12x12, 12x18, 12x20, 12x24, 12x28, 16x16, 16x20, 16x24 and 16x28, plus Compact 6x12, 6x16, 6x20, 8x12, 8x16 and 8x20. Composite kits come in 9 sizes from 12x12 to 16x28 in Amazon Gray or Forest Wood. Custom sizes are available on request.

Nor’easters and coastal storms bring wind-driven rain and wet snow, and summers are humid. Pick a spot that drains well, keep airflow under the deck and seal wood regularly or choose composite. If your home is near the water, check whether it sits in a flood zone, which can add requirements. Most Brooklyn decks go up between April and October, so plan and order over the winter.

Your kit ships by LTL freight, typically within 10–14 business days, and the carrier calls ahead to schedule curbside delivery. Many Brooklyn blocks have no driveways and tight parking, so plan where the components can be set down and how you’ll carry them to the backyard, often through the house or an alley. A few neighbors or friends make the carry much quicker.
