How much does a deck cost in Minnesota? Most homeowners pay $20,000 to $50,000 for a professionally built deck in 2026, depending on size, material, and features.
Quick summary:
- A typical 16×12 deck in the Twin Cities west metro starts around $20,000, well above generic national averages because of frost-depth footings and Minnesota labor rates.
- Composite and PVC decking cost more upfront than pressure-treated wood but need almost no maintenance through our freeze-thaw winters.
- Stairs, railings, permits, demolition, and elevation changes can add several thousand dollars to a deck project, and complex designs can add significantly more.
- A free interactive calculator can price your specific project by size, material, and add-ons in a few minutes.
How Much Does a Deck Cost in Minnesota Right Now?
Most Minnesota homeowners pay between $20,000 and $50,000 for a professionally built deck in 2026, with a standard 16×12 project starting around $20,000.
Larger decks, premium composite or PVC decking, and features like cable railing or underdecking push the total higher. Size drives most of the cost, but our frost line and snow loads add expenses that generic national guides do not account for.
That $20,000 to $50,000 range reflects real Twin Cities west metro projects, not a national blended average.
We build across Minnetonka, Plymouth, and Golden Valley, and pricing follows a consistent pattern in every one of those cities: bigger footprint, more stairs, and higher-end materials all move the number up in predictable steps.

Why Minnesota Numbers Run Higher Than Generic Online Estimates
Plenty of national cost guides quote lower per-square-foot ranges. Those numbers usually assume shallow footings and mild-climate labor rates.
Minnesota code requires footings below the frost line, which typically runs 42 inches deep across the Twin Cities metro. That single requirement adds the cost of excavation and concrete, or on the decks we build, helical pier footings, to the project.
What Is the Average Cost by Deck Size in Minnesota?
Deck cost scales almost directly with square footage once footing depth and labor are held constant for our region. The table below shows realistic 2026 installed pricing for common deck footprints built to Minnesota code, using pressure-treated lumber as the baseline material.
| Deck Size | Square Footage | Minnesota Installed Cost (2026) |
| 10×10 | 100 sq. ft. | $9,000 – $14,000 |
| 12×12 | 144 sq. ft. | $12,000 – $18,000 |
| 16×12 (with stairs) | 192 sq. ft. | $20,000 – $28,000 |
| 20×20 | 400 sq. ft. | $38,000 – $52,000 |
A few things push a project toward the top of its range: a second story or elevated deck, multiple stair runs, wraparound shapes, and any upgrade beyond pressure-treated lumber.
National data from Angi’s 2026 deck cost guide puts installed pricing at $30 to $60 per square foot, with the higher end reserved for second-story builds, premium wood, and custom designs. National guides like Angi are helpful as a starting point, but their square-foot pricing can make deck projects look simpler than they really are. In Minnesota, the final number depends less on a generic square-foot average and more on the full scope: stairs, railings, demolition, permits, access, elevation, framing details, and the materials selected.
How Much Does Each Decking Material Cost?
Material choice is the second biggest factor after size, and it changes both your upfront number and what you will spend over the next 15 years.
Here is what we see across our Wayzata, Eden Prairie, and Bloomington projects.
Pressure-Treated Wood
Pressure-treated lumber remains the most budget-friendly starting point. It runs lower on the front end but needs cleaning and staining every two to three years to hold up through our freeze-thaw cycles.
Cedar
Cedar costs more than pressure-treated wood and brings natural insect and rot resistance along with a warmer look. Maintenance is still required, just less often than standard lumber.
Composite Decking
Composite decking blends wood fibers with recycled plastic. Per Angi’s 2026 composite decking cost breakdown, installed composite pricing runs $15 to $32 per square foot, with materials at $5 to $18 per square foot and labor adding another $10 to $14. We install mostly TimberTech, with Deckorators as a regular alternative depending on the project.
PVC Decking
PVC decking is fully synthetic, so it resists moisture, insects, and mold better than any wood-based product. It costs more than composite up front but holds its shape through the wildest Minnesota temperature swings without warping. Wolf is our primary PVC brand, with AZEK installed when it fits the design better.
Table 2 below shows what homeowners actually notice five or ten years in, not just the sticker price.
| Material | Realistic Lifespan in Minnesota | Maintenance Frequency |
| Pressure-Treated Wood | 10 – 15 years | Clean and stain every 2 – 3 years |
| Cedar / Redwood | 12 – 18 years | Clean and seal every 2 – 3 years |
| Composite | 25 – 30 years | Occasional wash, no staining |
| PVC | 50+ years | Occasional wash only |

What Hidden Costs Should You Budget For?
Base square footage pricing rarely tells the whole story. These add-ons show up on almost every project we build in Plymouth, Minnetonka, and Golden Valley.
- Stairs. A full run of straight stairs can approach $10,000 once framing, labor, and proper footings are factored in.
- Railings. Aluminum and standard wood railings run in a moderate per-linear-foot range, while cable or glass panel systems cost noticeably more.
- Permits. Most cities in our service area require a permit for any deck attached to the house.
- Old deck demolition. Tearing out and hauling away an existing deck adds real cost before the new build even starts.
- Elevation. Second-story or elevated decks are more difficult to build, which can increase labor costs.
Minnesota-Specific Add-On Costs
| Add-On | Typical Minnesota Range |
| Underdecking system (dry space below deck) | $30 – $60 per sq. ft. of covered area |
| Cable or aluminum railing (per linear foot) | $60 – $150 |
| Frost-depth footing (per helical pier, 7-ft deep) | $600 – $850 |
| Standard residential permit turnaround | 2 – 3 weeks after plan submission |
Underdecking is worth a second look if you have a walkout basement or patio underneath. It turns unusable wet space into a dry storage area or seating spot, and it is one of the few add-ons that pays for itself in usable square footage rather than just curb appeal.
Should You Hire a Professional or Build the Deck Yourself?
Professional installation covers structural safety, code compliance, and a warranty on the work. DIY saves on labor but shifts all liability and troubleshooting to you.
Per HomeGuide’s 2026 deck cost data, permit fees for a residential deck typically run $50 to $150 depending on deck size and location, a small fraction of the total build regardless of who does the work. A typical deck in the Twin Cities runs anywhere from $300 to $500.
We are not going to pretend every project needs a crew. A small ground-level deck with basic structure is within reach for a handy homeowner.
What a Professional Build Actually Includes
- Framing designed for Minnesota code requirements, with engineering when required by the project or city
- Permit submission and inspection coordination
- Frost-depth footing installation
- Material warranties backed by the manufacturer
- A labor warranty on the workmanship itself
What Return Does a Deck Give You in Minnesota?
A deck typically returns 55% to 65% of its cost at resale in Minnesota, slightly below the national average because our shorter outdoor season limits year-round appeal to buyers.
The most recent Cost vs. Value Report figures show a wood deck addition returning roughly 65% of its cost nationally, with a composite deck addition returning around 62%.
Resale is only part of the equation. In a state with five solid months of usable outdoor season, most of our clients build a deck for the years of use, not the eventual sale.
Three Factors That Move Resale Value
- Condition and age of the decking and railing material at time of sale
- Whether the deck was permitted and built to current code
- How well the deck’s style matches the rest of the home’s exterior
What Should You Ask Before Hiring a Deck Builder?
Cost and timeline are the two questions every homeowner asks first, and both deserve a specific answer, not a ballpark. Beyond that, ask whether the crew is made up of employees or subcontractors, since that affects accountability on your jobsite every single day.
We use a consistent group of trusted crews and employees to manage each project through our own process, schedule, communication, and quality standards across Minnetonka, Plymouth, and Golden Valley. The important question is not just whether a builder uses employees or subcontractors, but whether the same accountable team shows up, communicates clearly, and follows a defined standard.
Questions Worth Asking Any Builder
- How much will this cost, and what is included in that number?
- How long will construction actually take, start to finish?
- Do you use employees or subcontractors on site?
- Will you provide drawings before construction starts?
- What is your process for permits and inspections?
- How do you keep the jobsite clean each day?
Communication, cleanliness, and craftsmanship separate a good deck build from a stressful one. Those three things show up in the first meeting, long before the first board gets cut.

Is a Deck or a Patio the Better Value for Your Backyard?
A deck typically costs more than a patio of the same size, but it also handles sloped yards, walkout basements, and elevation changes that a patio cannot. Patios work best on flat, well-drained lots, while decks give you options almost anywhere in the yard.
For homeowners in St. Louis Park or Maple Grove weighing both, the real deciding factor is usually the yard itself, not the price tag alone.

Getting an Accurate Number for Your Own Project
National averages are a starting point, not a quote. Your actual number depends on lot slope, soil conditions, material choice, and how many stairs and railings the design needs.
We have built decks across Minnetonka, Plymouth, Golden Valley, Eden Prairie, Wayzata, Bloomington, and Blaine, and no two quotes have looked exactly alike.
Size and scope stay within your control even when material prices shift year to year.
If you want a real conversation about your project, budget, and timeline, we would rather talk it through than have you guess from a table on a screen.
