Minnesota Deck Cost Estimator

1. Building season & climate in Minnesota

Minnesota has one of the shortest building seasons on this list — spring through early fall — with winter conditions ruling out most deck construction across the state.

2. Footing depth in Minnesota

Minnesota has some of the deepest footing-depth requirements in the country; local codes in the northern part of the state can require notably deep footings to get below the frost line. This is one state where confirming the exact local number before you dig matters more than most.

For the general reasoning behind frost-depth footing requirements, see the footing depth by frost line guide.

4. Typical cost for a 12×16 deck in Minnesota

A 12×16 deck is 192 sq ft. Applying the broad national installed-price ranges from our cost guide gives a starting range before Minnesota-specific factors:

What moves a Minnesota quote up or down from these national ranges:

• Required footing depth (section 2): deeper footings mean more concrete, digging, and labor per post.
• Building season (section 1): contractors often price higher in the busy months and may have openings, or schedule gaps, off-season.
• Deck height: a raised deck adds stairs, longer posts, and more railing.
• DIY vs. contractor: doing it yourself removes labor, which is a large share of the installed price.

5. Build your Minnesota deck estimate

General installed-price ranges by material are in the deck cost per square foot guide, with a full worked example in the 12×16 deck cost guide. For your own dimensions, start with the deck board calculator and work through joists, footings, fasteners, and railing.

Once you have your local footing depth from the building department, enter it in the footing concrete calculator to get bags of concrete per footing. The Project Summary then puts boards, joists, fasteners, concrete, and railing on one sheet you can export for the lumber yard.
