How Much Does a Garage Conversion Cost? 2025 Project Guide

Converting your garage into a functional living space is a savvy way to add value and versatility to your home. Whether you’re looking to create an extra bedroom, a home office, or even a complete in-law suite, knowing the cost of garage conversion is important to your decision-making.

Homeowners frequently wonder, “How much does it cost to convert a garage into a room?”. Ultimately, the answer depends on several factors, from the size of your garage to the materials and finishes you choose.

What is the Average Cost of a Garage Conversion in 2025?

In 2025, the average cost of a garage conversion is approximately $16,665, ranging from about $6,000 to upwards of $27,000. Of course, there are many ways to plan for a budget-friendly garage conversion; however, if you want to do a major remodel, you can expect your costs to be potentially far higher than the average.

With so much variation in price, the best approach is to learn more about the specific factors affecting the overall cost of converting a garage into a new space – which is exactly what this guide is designed to help you do.

Garage Conversion Cost by Square Foot

One of the simplest ways to plan your renovation budget is to look at the garage conversion cost per square foot. On average, you can expect to spend about $40 per square foot for a quality conversion project. However, prices can vary widely – basic finishes might run as low as $25 per square foot, while high-end upgrades or custom designs can push the cost up to $75 or more per square foot.

For example, if you have a typical one-car garage of around 240 square feet, you might pay between $6,000 and $18,000 to convert it, with most projects averaging close to $9,600. On the other hand, a larger two-car garage measuring roughly 440 square feet might cost anywhere from $11,000 to $33,000, averaging about $17,600.

These estimates provide a practical framework for determining the overall cost of garage conversion and can help you begin to answer common questions like, “How much does it cost to turn a garage into a room?”. Whether you’re planning to create a cozy bedroom, a spacious living area, or even an Accessory Dwelling Unit (ADU), understanding these per-square-foot costs is an essential first step in budgeting your project.

Garage Conversion Cost by Project Type

When planning your garage conversion, the project type plays a major role in determining overall costs. Each conversion has unique requirements, from structural changes to specialized installations.

Let’s take a closer break down several popular conversion options and the investment needed for each.

Bedroom

Converting your garage into a cozy bedroom is a popular way to create extra living space without adding on to your home. This project requires insulation, drywall, flooring, and window installation to ensure comfort and privacy.

On average, the cost to convert a garage to a bedroom ranges from $12,000 to $25,000. Key cost factors include the level of finish you choose, the amount of structural work needed, and local labor rates.

Bedroom with Bathroom

So, how much does it cost to convert a garage into a bedroom and bathroom? Keep in mind that this project requires additional work such as plumbing, electrical upgrades, and more extensive finishes.

Determining the exact expense of how much to convert a garage into a room with a bathroom depends on these factors, but typical costs can reach up to $25,000 or more. However, it can be a worthwhile investment, because a bedroom with an adjoining bathroom conversion creates a private suite ideal for in-law accommodations or guest quarters.

Office

Creating a dedicated workspace from your garage can significantly boost your productivity and work-life balance. An office conversion typically involves adding insulation, drywall, and reliable lighting to ensure a comfortable and quiet environment.

This project can be relatively straightforward. The average cost of a garage-to-office conversion is around $5,000, making it one of the more budget-friendly options for transforming your space.

Entertainment Room

An entertainment room conversion turns your garage into a lively area for movie nights, games, or gatherings with friends and family. The project may include installing soundproofing, custom lighting, and comfortable finishes to create an inviting atmosphere.

On average, an entertainment room conversion costs about $7,500. Factors such as media installation, acoustic treatments, and decor choices can influence the price.

Laundry/Utility Room

Converting your garage into a utility room can provide a practical space for laundry, storage, or even a workshop. This conversion often focuses on maximizing functionality with efficient layouts and durable materials.

A utility room conversion is a smart choice if you’re looking to organize your home better while adding value through additional usable space, costing somewhere around $6,000. Expenses will vary based on the extent of custom storage solutions and any additional electrical or plumbing work.

Apartment, Loft, Studio or Suite

For those considering a more significant transformation, converting your garage into an independent living unit can be a game changer. This project (sometimes referred to as a garage to ADU conversion) offers complete privacy and extra square footage for tenants or family members.

On average, the garage to ADU conversion cost runs about $30,000, but it’s an investment that will yield long-term benefits and potential rental income.

Gym

If you’re passionate about fitness but lack space at home, converting your garage into a personal gym is a fantastic solution. This conversion typically focuses on open space design, durable flooring, and proper ventilation to accommodate workout equipment and high-intensity activities.

Typically, converting a garage into a gym costs around $6,000. The total cost depends on factors like equipment selection, flooring quality, and any additional modifications for safety and efficiency.

Kitchen

Transforming your garage into a kitchen requires significant planning and investment, as it involves plumbing, cabinetry, and high-quality appliances. A kitchen conversion can completely change how you use your home, providing a modern, functional cooking space that’s perfect for entertaining. This type of conversion is usually one of the more expensive projects but can dramatically enhance your home’s overall appeal.

The average kitchen conversion typically ranges from $20,000 to $50,000. Costs are driven by the complexity of layout changes, the quality of materials selected, and the extent of custom features such as countertops and custom cabinetry.

Converting a Double Garage

If you have a larger, double-car garage, the potential for conversion increases dramatically. Converting a double garage often means reconfiguring the space to include multiple rooms or a larger single living area. This project can be complex, as it may involve reworking the structure and installing additional utilities, but it offers a tremendous opportunity for expanding your home’s livable area.

How Much Does It Cost to Convert a Carport Into a Garage?

A carport to garage conversion is a great option for homeowners hoping to add security and functionality to their property. The cost depends on factors such as the size of the carport, materials used, and local labor rates. On average, these projects can range from $10,000 to $20,000, making it a competitive way to boost your home’s value and protection.

DIY Garage Conversion Costs

While DIY projects might seem like a way to save money, garage conversions typically involve complex electrical, plumbing, and structural work. Attempting a conversion without professional help can lead to costly mistakes and safety issues. Most homeowners find that the expertise of a contractor is essential to ensure excellent results, safety, and code compliance.

Cost to Hire a General Contractor for a Garage Conversion

Hiring a general contractor helps streamline your conversion project and guarantees professional results. Contractor fees generally add an extra 10-20% to the overall budget, covering labor, project management, and permit acquisition. Their expertise ensures that your conversion meets local building codes and is completed on schedule, making this investment well worth it.

Cost to Convert a Garage Into a Living Space by Location

The overall price to convert a garage into a living space varies widely by location. In areas with higher permit fees and labor costs, the project may be more expensive, whereas more rural regions can offer lower costs. Researching local averages helps set a realistic budget and ensures you understand the market conditions in your area.

Additional Factors That Influence the Cost to Convert a Garage Into a Living Space

Beyond basic construction, several additional factors can significantly impact your overall budget.

Permits

Permit fees vary by municipality and ensure your project meets local building codes.

Electrical

Upgrading electrical systems for lighting and appliances can add considerable expense.

Plumbing

Adding plumbing for bathrooms or kitchens is often one of the costlier components.

Doors

Installing new doors or modifying existing ones is an important budget consideration.

Windows

New windows improve natural light but may increase costs.

Insulation

Proper insulation is crucial for energy efficiency and comfort.

HVAC

Extending or installing HVAC systems can be a major part of the budget.

Flooring

Quality flooring enhances aesthetics and durability, affecting overall costs.

Drywall

Finishing walls with drywall is essential for a finished look and varies with quality.

Converting a Garage Into a Living Space Yourself vs. Hiring a Pro

While a DIY approach might seem cost-effective, converting a garage into a comfortable living space is a complex project. Professional contractors bring expertise in structural changes, electrical, plumbing, and permit acquisition. This ensures a safe, compliant, and high-quality conversion, often saving money in the long run by avoiding errors and delays.

Ways to Save Money on Garage Conversion Projects

To keep costs down, consider shopping for competitive quotes and opting for cost-effective materials that still meet quality standards. You might also handle simple cosmetic tasks yourself, like painting or minor finishing touches, while leaving complex work to the pros. Detailed planning and budgeting are key to uncovering additional savings without sacrificing quality.

Does a Garage Conversion Add Value to a House?

A well-done garage conversion can significantly increase your home’s value by adding functional living space. It enhances both the aesthetics and utility of your property, making it more appealing to potential buyers. However, the added value depends on the quality of the conversion and local market preferences. In many cases, homeowners find that the conversion pays for itself in increased resale value and improved quality of life.

Frequently Asked Questions

What makes a garage count as living space?

A garage becomes a living space when it’s transformed into a room that meets residential building codes and is comfortable for everyday use. That means it’s properly insulated, has heating or cooling, finished walls and flooring, and includes windows and safe exit routes. If you can use it as a bedroom, office, family room, or similar area, then it qualifies as living space. This conversion not only adds functional square footage to your home but can also boost its overall market value.

How long does a garage conversion take?

Most garage conversions take between 2 and 6 weeks to complete. The timeline depends on the scope of your project – simple updates like finishing walls and flooring may be quicker, while conversions involving plumbing, electrical work, or major structural changes can take longer. Factors such as weather, permit approvals, and contractor scheduling also play a role. Working with experienced professionals helps ensure that your project stays on track and minimizes any unexpected delays.

Do I need an architect for a garage conversion?

It really depends on your project. For basic conversions that involve finishing the space without major structural changes, you might not need an architect. However, if your plans include significant modifications, such as adding new rooms or altering the layout, hiring an architect can be extremely helpful. An architect will design a space that is both practical and attractive, ensure it meets building codes, and help smooth the permitting process – ultimately saving you time and avoiding costly mistakes.

Do garage conversions require planning permission?

Yes, garage conversions typically require planning permission and building permits. Local authorities need to ensure that the converted space meets safety standards and building codes, which cover aspects like insulation, ventilation, and emergency exits. Securing the proper permits is essential to avoid delays or fines, and it helps guarantee that your new living space is safe and compliant with regulations. Consulting with a contractor who is familiar with local permit requirements can make the process much smoother.

Can I convert a detached garage into a living space?

Absolutely, you can convert a detached garage into a living space. However, there are a few extra considerations. You’ll likely need to extend your home’s utilities (such as water, electricity, and HVAC) to the detached structure, and ensure that it meets the same building code standards as an attached living area. With proper planning and professional help, a detached garage can be transformed into a cozy guest suite, home office, or additional living area, enhancing your property’s functionality and value.

Does converting a garage devalue your house?

Converting a garage doesn’t automatically devalue your house – in many cases, it can actually increase your property’s value by adding usable living space. A well-executed conversion that creates an extra bedroom, office, or family room often enhances your home’s appeal. That said, in areas where a garage is highly prized for vehicle storage or protection, some buyers might miss the original space. It all comes down to local market preferences, but generally, adding functional space tends to boost overall home value.

Does converting a carport to a garage add value?

Yes, converting a carport into a fully enclosed garage can add significant value to your home. An enclosed garage provides better security and protection for your vehicle and belongings, and it often looks more appealing to potential buyers. This added functionality and enhanced curb appeal can make your property more attractive on the market, often resulting in a higher resale value.

What should I do with my driveway after a garage conversion?

After converting your garage, you may need to revisit your driveway’s layout and condition to ensure it still works well with your home’s new look. Sometimes, a simple reconfiguration or resurfacing can improve access and complement your updated exterior. You might also consider adding landscaping or decorative elements to tie everything together. Consulting with a contractor or landscape professional can help determine if any modifications are needed to maintain both functionality and curb appeal.
