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

Yes to both. Arvada and the surrounding Jefferson County area have many deck contractors, so get two or three written quotes and ask for proof of insurance and recent local projects. If you’d rather build your own deck, A-DIY delivers professionally engineered wood and composite deck kits to Arvada homes, and you or a local handyman can assemble one with just a drill.

Size, material, height, footings, permits and labor all drive the price. A-DIY deck kits range from $3,699 for a 6x12 pressure-treated kit to $12,799 for a 16x28 composite kit. Building it yourself is usually cheaper because labor makes up much of a contractor’s quote, and homeowners typically spend 30–50% less than hiring a contractor. Kit prices don’t include permits, site prep or hired help.

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.

Often. Inside city limits, permits come from City of Arvada Building Services, which updated to codes based on the 2024 International Codes on July 1, 2026. Attached decks, covered decks and decks more than 30 inches above grade typically need a permit, and homes in mapped wildfire risk zones may face extra deck requirements. Some Arvada mailing addresses are in unincorporated Jefferson or Adams County, so confirm which office covers your lot.

The International Residential Code that Arvada builds on generally exempts a deck that is 200 square feet or smaller, no more than 30 inches above grade, not attached to the house and not serving a required exit door. A-DIY’s Compact Series (6x12 to 8x20), the 12x12 kit and the 12x16 composite kit are all under 200 square feet. Arvada can amend these rules, and wildfire-zone and zoning rules can still apply, so confirm with Building Services first.

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.

Arvada lists a 36-inch frost depth, so footings for attached or elevated decks generally need to reach at least that deep. Freestanding ground-level decks are treated differently, and A-DIY kits sit on included Tuff Block footings. Expansive soils are common along the Front Range, and acceptance of a floating design is up to the building official, so ask Building Services before you build.

Arvada sits more than a mile high near the foothills, so decks deal with intense UV, dry air, strong winds, spring snow, freeze-thaw cycles and hail. Parts of the city are mapped for wildfire risk, where deck materials may be regulated. Seal pressure-treated wood every one to two years or choose composite, and clear heavy snow with a plastic shovel.
