2-Story Attached Garage Addition

Are you looking to add more living space to your home without the hassle of building an entirely new addition? Adding a second story to your attached garage might be the perfect solution.

In this article, we’ll explore the benefits and challenges of this type of project and provide you with essential tips for planning a successful 2-story attached garage addition.

Benefits of Adding a Second Story to Your Attached Garage

  1. Increased Living Space: One of the most significant advantages of adding a second story to your attached garage is the potential to gain up to 500 square feet of extra living space. This newfound space can serve various purposes, such as a bedroom, office, playroom, or even a home gym.
  2. Increased Property Value: Another appealing aspect of this addition is its potential to boost your home’s value by up to 20%. It’s an excellent investment that not only provides you with more space but also increases the resale value of your property.
  3. Lower Construction Costs: Since your garage already has an existing foundation, the construction costs for adding a second story will be notably lower than building a completely new addition. This cost-effectiveness makes it an attractive option for expanding your living area.

Challenges to Consider

While a 2-story attached garage addition comes with many benefits, it’s essential to be aware of the challenges involved:

  1. Permitting: Before embarking on this project, obtaining a permit from your local government is crucial. The permitting process may take several weeks, so it’s essential to start early to avoid delays.
  2. Structural Engineering: A structural engineer will need to assess your home’s foundation to ensure it can support the additional weight of a second story. If any modifications are required to enhance the structural integrity, they will need to be addressed before construction begins.
  3. Cost: The total cost of this project can vary significantly based on its size and complexity. On average, you can expect to invest between $50,000 to $100,000 for a 2-story attached garage addition.

Planning Your 2-Story Attached Garage Addition

As you start planning your project, here are some essential factors to consider:

  1. Home Height: The height of your home plays a crucial role in determining the size of the second story rooms. Ensure that your home is tall enough to accommodate the desired space. If needed, consider adding dormers or skylights to increase headroom.
  2. Matching Roofline: To maintain a cohesive and aesthetically pleasing look, the roofline of the second story should align with the existing roofline of your main house.
  3. Ample Windows and Natural Light: Plan for large windows on the second story to allow plenty of natural light to flood the space. Consider incorporating skylights for additional brightness and an airy atmosphere.
  4. Durable Flooring: Choose durable and easy-to-maintain flooring options for the second story. Hardwood floors are a popular choice, but you may also explore options like tile or laminate.
  5. Safe and Well-Lit Staircase: The staircase leading to the second story should be wide, well-lit, and safe. You may consider adding a railing for enhanced safety.
