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

You have both options. Littleton and the south metro have many deck contractors, so compare two or three written quotes with proof of insurance and recent local projects. If you would rather build your own deck, A-DIY delivers professionally engineered wood and composite deck kits to Littleton homes, and you or a local handyman can assemble one with just a drill.

Cost depends on size, material, height, footings, permits and labor. A-DIY deck kits range from $3,699 for a 6x12 pressure-treated kit to $12,799 for a 16x28 composite kit. Doing the work yourself is usually cheaper since labor is a large share of a contractor’s price, 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.

Inside City of Littleton limits, yes: the City’s Building Division states that all decks require a building permit. Many homes with a Littleton mailing address are actually in unincorporated Arapahoe, Jefferson or Douglas County, or in nearby cities such as Centennial, and those offices set their own deck rules. Check which government covers your lot first.

Inside the City of Littleton, there is no size exemption for decks; the City requires a building permit for all of them, including small freestanding ones. If your Littleton address is in unincorporated Arapahoe, Jefferson or Douglas County or in another city, different exemptions may apply, so confirm with that building office before you build.

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.

Footing depth comes from each building office’s design criteria, and Front Range jurisdictions commonly require 30 to 36 inches to get below the frost line, so confirm Littleton’s figure with the Permit Center. A-DIY kits are freestanding and sit on included Tuff Block footings, but acceptance of a floating design is up to the building official, and expansive soils are common in the area.

Littleton sits more than a mile high along the South Platte River, so decks face intense UV, dry air, wide temperature swings, spring snowstorms, freeze-thaw cycles and summer hail. Seal pressure-treated wood every one to two years or choose composite, and clear heavy snow with a plastic shovel. Applicable A-DIY configurations are engineered for up to 15,000 lbs when properly assembled and supported.

Late spring through early fall. Since every deck inside city limits needs a permit, start the application over the winter so you can build once spring snow has melted. A-DIY Reserve holds today’s price for a future delivery date with a $250 non-refundable deposit.
