Deck Builders in Minnesota: MN Deck Costs, Permits and a Faster Way to Build

Minnesota homeowners can hire a local deck builder, frame a deck themselves from raw lumber, or order an A-DIY engineered deck kit. The A-DIY kit arrives at your door as one complete system, and you, a friend or a local handyman can assemble it in a few hours with nothing more than a drill.

A Minnesota contractor’s price depends on the deck’s size, the decking material, how high it sits, whether frost footings are needed and local labor rates, and bids in the Twin Cities metro usually come in above those in Greater Minnesota. A-DIY deck kits start at $3,699 for pressure-treated wood and $5,700 for composite, typically 30–50% less than hiring a contractor. Use our deck cost calculator to compare prices in your area.

Yes. An engineered deck kit delivers a true structural deck without the cost of a contractor’s design time and a full crew. The A-DIY kit ships with everything you need, footings included, so there is no measuring, no cutting and no running back to the lumber yard for parts.

No. A-DIY is not a contractor and does not install decks. We design, engineer and deliver complete deck kits to addresses across Minnesota. Put it together yourself or hire any local handyman, carpenter or contractor to handle the assembly.

Yes. Many Minnesota homeowners have a local handyman assemble their A-DIY kit. Because every part arrives ready to assemble with step-by-step instructions, the job takes a fraction of the hours a custom build would, which keeps the labor bill small.

Usually. The Minnesota State Building Code applies statewide, and under its permit rules a deck is exempt only if it is no more than 30 inches above grade, not attached to a structure with frost footings and not part of an accessible route. Anything higher or attached to the house needs a permit from your city or county building department, so check with them before you order.

In Minneapolis, deck permits are issued by Construction Code Services within the Community Planning and Economic Development department. The city requires a permit for deck projects, even a replacement of the same size, and exempts only a deck under 30 inches with no door access to the house, which still needs zoning approval. You submit a site plan, framing plan and cross section, footings must reach 42 inches, and inspectors check footings, framing and the finished deck.

Minnesota Rules 1303.1600 sets frost footing depth by county: at least 60 inches in the northern zone, which includes St. Louis, Carlton and Beltrami counties, and at least 42 inches in the southern zone, which includes Hennepin, Ramsey, Dakota and Olmsted, unless a soils engineer justifies less. A freestanding deck no more than 30 inches above grade and not attached to a frost-footed structure is exempt from a state building permit, but your city decides what it needs underneath, so confirm locally.

Yes. On a sloped or uneven Minnesota lot, an A-DIY deck is leveled by adjusting the heights of the supporting posts instead of regrading the yard. Supported configurations can be elevated to approximately 40 inches using the appropriate posts, foundations and bracing.

Every A-DIY kit includes Tuff Block footings. Where your site, deck height or local frost rules call for something different, the deck can be set instead on sonotubes, helical piles, ground screws, in-ground posts or an approved surface footing system.

Both hold up in Minnesota. Pressure-treated wood costs less upfront and takes stain or sealer well, but months of snow, repeated freeze-thaw cycles and humid summers mean it needs cleaning and resealing on a regular schedule. Composite costs more but never needs sanding, staining or sealing, resists fading and splintering, and its boards carry a 25-year warranty.

Applicable A-DIY deck configurations are engineered to hold up to 15,000 pounds when properly assembled, supported and installed according to the applicable specifications. Every A-DIY deck system also includes a five-year structural warranty.

A-DIY delivers to cities and towns across Minnesota, typically within 10–14 business days. All the components and hardware arrive together, so you can start assembling as soon as the shipment is in your driveway.

Yes. You can choose Build Now, Pay Later financing through Affirm (subject to approval), 0% split payments over up to eight months, or A-DIY Reserve, a $250 deposit that locks in today’s price for a future delivery date.

Yes. For an applicable A-DIY configuration, the diagrams show the dimensions, structural layout, beam, joist and post locations, lumber sizes and major connections, which is the kind of detail Minnesota building departments ask for with a deck permit application. Your local department may still require a site plan, survey or stamped documents, and it has the final say, so approval is not guaranteed.
