How to Build an Above Ground Deck in Minneapolis

Building an above ground deck in Minneapolis requires careful planning, adherence to local building codes, and attention to weather considerations due to the city’s climate.

Here’s a step-by-step guide to help you build your deck:

1. Check Local Regulations. Before you begin, contact the Minneapolis building department to obtain necessary permits and ensure compliance with local building codes and regulations.
   
2. Design and Plan. Think through the size, shape, and location of your deck, considering factors such as sun exposure, accessibility, and views. Sketch out your design and create a materials list.
   
3. Gather Materials. Purchase all the necessary materials for your deck construction, including lumber for the frame and decking, concrete footings, fasteners, and any additional materials for railings or stairs.
   
4. Prepare the Site. Clear the area where the deck will be built, removing vegetation, rocks, or debris. Ensure the ground is level, and mark the locations for the footings.
   
5. Install Footings. Dig holes for the footings according to the local building codes and your deck design. Typically, footings are spaced evenly along the deck’s perimeter and support the structure’s weight.
   
6. Set Posts and Frame. Install the posts into the footings and secure them with concrete. Then, construct the deck frame using pressure-treated lumber, ensuring it is square and level.
   
7. Install Decking Boards. Once the frame is complete, install the decking boards perpendicular to the joists. Leave a small gap between each board to allow for expansion and drainage.
   
8. Add Railings. If your deck requires railings, install them according to the manufacturer’s instructions. This may involve attaching posts to the deck frame and then installing balusters and a top rail.
   
9. Finish the Deck. Apply desired finishes or sealants to protect the wood from moisture and weather damage. This step is crucial in Minneapolis due to its varying climate.
   
10. Install Stairs (if needed). If your deck is elevated, you’ll need stairs for access. Follow the appropriate guidelines for building safe and sturdy stairs, ensuring proper rise and run dimensions.
    
11. Inspect and Maintain. Once your deck is complete, inspect it regularly for signs of damage or wear. Perform routine maintenance, such as cleaning and sealing, to prolong its lifespan.

Once everything is done and your deck is safe and secure, you can relax and enjoy your outdoor space with friends and family!

Determining the Size of Footings for Second Story Deck

The size of footings for a second-story deck in Minneapolis depends on several factors, including the deck’s size, load-bearing requirements, local building codes, soil conditions, and the specific design of the structure. Generally, larger decks or decks with heavier loads will require larger footings to provide adequate support and stability.

Here are general guidelines for sizing footings for a second-story deck in Minneapolis:

• Consult Local Building Codes: Check Minneapolis-specific building codes and regulations. Our team can help provide footing size, depth, and spacing requirements based on soil type, frost depth, and expected loads.

• Determine Load Requirements: Consider the size and weight of the deck, including any additional features such as hot tubs, furniture, or large gatherings of people. This will help determine the required bearing capacity for the footings.
  
• Calculate Footing Size: Footings are typically sized based on the expected loads and soil-bearing capacity. In Minneapolis, where frost depth can be significant, footings may need to extend below the frost line to prevent heaving. The footing size will depend on soil type, deck size, and local code requirements.
  
• Consider Beam and Joist Spans: The spacing and size of footings should also take into account the spacing of the beams and joists they will support. You’ll want your footings spaced evenly and positioned.
  
• Factor in Site Conditions: Site conditions such as soil type, drainage, and proximity to trees or other structures can also influence footing sizing. Compacted soil, for example, may require smaller footings than loose or sandy soil.

Pro-tip: Prioritize safety throughout construction, especially when working with power tools and heavy materials. Consult a professional contractor or carpenter if you’re unsure about building your deck.

Above Ground vs. In Ground Decks

Choosing between an above ground and in-ground deck in Minneapolis depends on your preferences, budget, and site conditions. Here’s a comparative breakdown between the two:

Above Ground Deck

• Ease of Construction. Compared to in-ground decks, these decks are generally easier and faster to build. They require less excavation and groundwork, making them a more straightforward DIY project for many homeowners.
  
• Versatility. They can be built on various terrain types, including sloped or uneven ground, without extensive excavation or modification. This versatility makes them suitable for a wide range of locations and property types.
  
• Accessibility. Since they are elevated, these decks provide easy access from the indoors and often offer better views of the surrounding landscape. They can also be built at a height that aligns with the interior floor level, creating a seamless transition between indoor and outdoor spaces.
  
• Durability. Above ground decks are typically less prone to moisture-related issues such as rot and decay since they are elevated above the ground. Proper construction and maintenance can ensure their longevity, even in Minneapolis’ climate with its cold winters and humid summers.
  
• Cost. In general, above ground decks are more cost-effective than in-ground decks since they require fewer materials and labor for construction. However, the total cost will depend on the deck size, the materials used, and additional features like railings or stairs.

In-Ground Deck

• Aesthetics. Since they’re level with the ground, in-ground decks can be sleeker and integrate better with the surrounding landscape. They may be preferred for properties with a more natural or contemporary design aesthetic.
  
• Space Utilization. In-ground decks maximize usable outdoor space since they don’t occupy as much vertical space as above-ground decks. They can also provide more privacy than elevated decks.
  
• Stability. These decks can offer enhanced stability and structural integrity, especially if securely anchored. This can be advantageous in areas with high winds or heavy snow loads, such as Minneapolis.
  
• Long-Term Maintenance. While in-ground decks may require less maintenance in terms of moisture-related issues, they may be more susceptible to issues like drainage problems and ground settlement over time. Proper site preparation and drainage considerations are crucial for mitigating these risks.
  
• Cost. In-ground decks tend to be more expensive and labor-intensive to build than above-ground decks, primarily due to the required excavation and foundation work. Homeowners should budget accordingly for excavation, foundation materials, and labor costs.

Ultimately, the decision will depend on your preferences, budget, site conditions, and long-term maintenance considerations. If you have questions, we’re always here to help.
