(FOUR FACTORS) Why Consider a Basement in Wisconsin?

If you’re building a new home in Wisconsin, you may be wondering whether or not you need a basement.

While it’s not strictly necessary, there are several reasons why you might want to consider including a basement in your home design.

1. Protection from Extreme Weather

Wisconsin is known for its extreme weather conditions, including heavy snowfall, thunderstorms, and tornadoes.

Having a basement can provide you and your family with a safe place to shelter during severe weather events.

In addition, a basement can help protect your home from flooding, which can be a real concern in areas with heavy rainfall or melting snow.

2. Extra Living Space

If you’re looking to maximize your living space, a basement can be a great option.

With a finished basement, you can add extra bedrooms, a home office, or a recreational area for your family to enjoy. This can be especially useful if you have a large family or frequently host guests.

3. Increased Home Value

Adding a basement to your home can also increase its resale value. According to some estimates, a finished basement can add up to 10% to the value of your home. This means that including a basement in your home design can be a smart investment in the long run.

4. Cost Considerations

Of course, there are also some cost considerations to keep in mind when deciding whether or not to include a basement in your home design. The cost of building a basement can vary depending on a number of factors, including the size of your home and the materials used. However, in general, building a basement can be more cost-effective than adding an additional story to your home.

Overall, whether or not you decide to include a basement in your home design will depend on your individual needs and preferences. However, if you’re looking for extra living space, protection from extreme weather, and increased home value, a basement can be a smart choice for your Wisconsin home.

Basement Regulations in Wisconsin

If you do decide to include a basement in your construction plans, there are certain regulations you need to be aware of.

1. Building Permits

Before you start any construction work, you’ll need to obtain a building permit from your local municipality.

This permit ensures that your construction plans meet all the necessary safety and building codes.

Failure to obtain a permit can result in fines and even legal action, so it’s important to follow all the necessary procedures.

2. Egress Window Requirements

If you plan to use your basement as a living space, you’ll need to install egress windows. These windows provide an emergency escape route in case of a fire or other emergency.

According to the Department of Safety and Professional Services, egress windows must meet the following requirements:

  • Minimum clear opening width of 20 inches
  • Minimum clear opening height of 24 inches
  • Minimum net clear opening of 5.7 square feet
  • Maximum sill height of 44 inches above the floor

3. Overhead Door Specifications

If you plan to have an overhead door in your basement, it must meet certain specifications.

According to the Department of Safety and Professional Services, overhead doors must have:

  • A minimum height of 6 feet 8 inches
  • A minimum width of 2 feet 6 inches
  • A minimum headroom of 6 inches above the door opening

In addition, the door must be equipped with an automatic closing device that can be activated by a smoke detector or heat sensor.

Remember, it’s important to follow all the necessary regulations when building a basement in Wisconsin. By obtaining the necessary permits and following the safety codes, you can ensure that your construction project is a success.

TWO Construction Considerations for Basements

If you are considering adding a basement to your Wisconsin home, there are several construction considerations you should keep in mind.

These include joist and truss considerations, as well as bathroom and closet planning.

1. Joist and Truss Considerations

When constructing a basement, it is important to consider the type of joists or trusses that will be used to support the floor above.

In general, floor joists should be at least 2×8 inches, and spaced no more than 16 inches apart. Trusses should also be spaced no more than 16 inches apart, and should be designed to handle the weight of the floor above.

It is also important to consider bridging and fastening when installing joists or trusses. Bridging, which involves installing diagonal braces between the joists or trusses, can help prevent them from twisting or bending.

Fastening, which involves using nails or screws to secure the joists or trusses to the walls, can help ensure that they stay in place.

2. Bathroom and Closet Planning

If you plan to include a bathroom or closet in your basement, there are several planning considerations you should keep in mind.

First, you will need to ensure that there is adequate space for these features. A bathroom will typically require at least 30 square feet, while a closet will require at least 24 square feet.

You will also need to consider the location of plumbing and electrical lines. Plumbing lines will need to be installed to connect the bathroom fixtures to the main sewer line, while electrical lines will need to be installed to power any lighting or electrical outlets in the basement.

To ensure that your basement meets all necessary construction codes and regulations, it is recommended that you work with a licensed contractor or architect. They can help you design and construct a basement that meets your needs and is safe and structurally sound.

Hiring a Contractor for Basement Construction

If you’re considering building a basement in Wisconsin, you’ll need to hire a contractor to ensure your construction project is successful.

Here are some things to keep in mind when choosing a contractor for your basement construction project.

1. Choosing a Contractor

When selecting a contractor, it’s essential to choose someone with experience in basement construction.

You should ask for references and check their previous work to ensure that they have the necessary skills and expertise to complete your project.

You can also ask friends and family for recommendations or search for contractors online.

Once you’ve narrowed down your list of potential contractors, you should ask for written estimates from each of them. Be sure to compare these estimates carefully to ensure that they include all the necessary work and materials.

2. Documentation and Permit Applications

Your contractor should be able to provide you with the necessary documentation for your basement construction project.

This includes a written contract that outlines the scope of the work, payment terms, and estimated completion date. You should also receive a detailed list of the materials that will be used in your basement construction project.

Your contractor should also be familiar with the permit application process in Wisconsin. They should be able to apply for the necessary permits and ensure that all inspections are completed on time.

This will help to ensure that your basement construction project is completed safely and meets all local building codes.

FOUR Alternatives to Basements In Wisconsin

If you are building a new home or considering a remodel, you might be wondering if you really need a basement.

While basements are a popular choice in Wisconsin, there are several alternatives to consider.

1. Slab-on-Grade Foundation

A slab-on-grade foundation is a popular alternative to a basement. It is a concrete slab poured directly on the ground, with no space between the slab and the soil.

This type of foundation is less expensive than a basement, and it is easier to install. It also eliminates the need for a crawl space, which can be a source of moisture problems.

2. Garage

If you need extra storage space or a workshop, consider building a garage.

A garage can be attached or detached from your home, and it can be designed to match the style of your home.

A garage can also add value to your home, and it can be a great place to park your car during the winter months.

3. Deck

If you want to add outdoor living space to your home, consider building a deck.

A deck can be a great place to relax and entertain, and it can add value to your home.

There are many different types of decks to choose from, including wood, composite, and PVC.

4. Remodel

If you need more living space, consider a remodel. You can add a room or two to your home, or you can convert an existing space into a bedroom or office. A remodel can be a great way to update your home and make it more functional.

DeckAdds outdoor living space, can add value to your home
RemodelAdds living space, updates your home

Overall, there are many alternatives to basements that you can consider. Each option has its own pros and cons, so it’s important to weigh your options carefully before making a decision.


In Wisconsin, having a basement is a common feature in many homes. However, whether or not you need a basement depends on your personal preferences and needs.

If you are looking for additional living space, a basement can provide a cost-effective solution. Finishing a basement adds value to your home and can be used for a variety of purposes such as a family room, home theater, or even a guest suite. The cost to finish a basement in Wisconsin can range from $60 to $120 per square foot, depending on the scope of work and amenities being installed.

On the other hand, if you are concerned about the potential for flood damage, a basement may not be the best option for you. Wisconsin is known for its heavy rainfall and snowmelt, which can cause flooding in low-lying areas. If you live in a flood-prone area, you may want to consider building a home without a basement or installing a sump pump to prevent water damage.

Another consideration is the type of soil in your area. Wisconsin has a variety of soil types, including clay and loam, which can affect the stability of your foundation. If your home is built on unstable soil, you may want to consider building a home without a basement or installing additional foundation support.

Ultimately, the decision to include a basement in your home is a personal one. Consider your needs and preferences, as well as the potential risks and benefits, before making a final decision.
