How Much Does a Laundry Room Addition Cost? [2026 Data]

A standard laundry room addition costs between $5,000 and $45,000, depending on whether you opt for high-end materials. Most homeowners spend an average of $15,000 or $250 per square foot when they add a new laundry room. However, the cost per square foot isn't linear, and your addition could cost as little as $140 per foot or as much as $300.

Preparation Cost of a Laundry Room Addition

Making your laundry room remodeling ideas a reality requires a bit of planning. For instance, to obtain the necessary building permits, you'll need a set of plans from an architect or designer. To get the plans approved by your municipality, a structural engineer could have to sign off on them.

Additionally, many homeowners choose to hire an interior designer to help make the new space the best it can be. Due to the smaller nature of the project, the costs for these services will be lower than for a large remodel. 

• Permit cost: $150–$2,000

• Architect cost: $550–$2,200

• Structural engineer cost: $350–$800

• Interior designer cost: $200–$2,100

Size of the Laundry Room Addition

Your new laundry room’s size will be the biggest factor influencing the price. The larger the finished room size is, the more it will cost to fit it out with cabinetry, flooring, wallcovering, and countertops.  

Foundation and Framing Costs

Your new laundry room will need walls, a foundation for them to rest on, a roof that incorporates into your existing one, siding, and insulation to meet the building code in your location. 

• Foundation costs: $1,200–$4,000

• Framing costs: $500–$1,600

• Siding costs: $600–$3,000

• Insulation costs: $150–$400

• Roofing costs: $400–$1,300

Utility Costs

Utility installation costs can vary by the size of your laundry room addition. However, the most significant cost variations involve adding new features and tying the new electrical, plumbing, and HVAC components into your home's existing systems. 

• Electrician costs: $40–$120 per hour

• Plumber costs: $45–$200 per hour

• HVAC installer costs: $50–150 per hour

Finishing Costs

Finishing a new laundry room requires adding floor coverings, wall coverings, cabinetry, and appliances. You may want to make it beautiful with tile, paint, and other personal touches. Finishing costs will relate directly to the size of your addition, with the exception of the laundry machines. 

• Drywall costs: $1.50–$3 per square foot

• Cabinetry costs: $100–$300 per linear foot

• Painting costs: $2–$6 per square foot

• Tile costs: $3–$15 per square foot

• Flooring costs: $3–$25 per square foot

General Contractor Cost

While you could hire a specialist for each individual portion of your laundry room build, most homeowners consolidate the costs and leave the project management to a general contractor or home remodeling contractor. If you choose to hire one, your renovation contract will contain details of all the steps necessary to complete the project, along with expected completion dates and other essential information. Hiring a contractor to handle everything involved costs between 20% and 50% of the total price of the project. 

Additional Pros to Consider Hiring

Depending on the layout, size, and desired functionality of your laundry room addition, installing a window or two is a nice touch. Another common add-on for larger laundry room additions is the inclusion of an exterior entry door. An entry door in the laundry room is an excellent access point if you like to hang clothes out to dry. 

• Window installation costs: $150–$800 each

• Entry door installation costs: $230–$3,600

Additional Cost Factors

Not all laundry rooms are created equal. However, each one will require additional costs that don't neatly fall into typical categories. While some of the following items could be included in your contract, some are not. 

Demolition and Prep 

The cost to make a hole in the side of your house to accommodate your new addition is highly variable and will depend on your plan's specifics. Demolition and prep work, not including the foundation requirements, will cost between $4 and $17 per square foot. 

Post-Construction Cleanup

Plan on budgeting between $140 and $700 to clean up the site and your home after the addition is complete and the dust settles. While this cost may be part of your contract, post-construction cleaning costs are not often included. 

Repurposing the Old Laundry Room

If your new laundry room addition is taking the place of an existing laundry room that didn't fit your needs, how you choose to use the now vacant space is up to you. You'll need to spend between $100 and $500 to cap off, remove, repurpose, or disable the existing plumbing, electrical, and HVAC. But any other costs will depend on what you decide to do with it. 

Landscaping

Installing an addition to your home is an excellent time to upgrade your landscaping to match the new look of your home. Landscaping costs vary widely, from as little as $200 to over $15,000. 

Why You Should Hire a Home Remodeler

If you’re particularly handy, it’s possible to make small updates to your laundry room. However, a large laundry room addition or remodel is a complicated undertaking that requires specialized skills and equipment—especially if you’re moving plumbing or considering a home addition. Hiring a local remodeling contractor is wise when factoring in the time, commitment, and management of tasks involved with this large-scale project. 

Here’s why it’s ideal to hire a home remodeling pro 

Leaving a big job like a laundry room upgrade to the pros is worthwhile because of these benefits:

• Contractors can route plumbing and drain lines without causing leaks or slow drainage.

• They install electrical wiring to code for grounded, high-wattage appliances, such as washers and dryers.

• Home addition contractors evaluate whether the existing flooring is strong enough to support the weight and vibration of laundry machines.

• They’ll adjust the layout to reduce noise transfer to living areas.

• Home remodelers have the expertise to manage permitting and coordinate the trades and contractors required for the job.

If you want to DIY a laundry room

Leave larger renovations and room additions to contractors with specialized experience—but if you’re simply redecorating an existing room, not moving plumbing lines, electrical outlets, or the dryer vent—you can take on some smaller tasks:

• Paint walls and cabinets with moisture-resistant paint for a fresh, clean look.

• Install shelving or wall organizers, such as open shelving, cubbies, and pegboards, for storing laundry supplies.

• Install a folding table to serve as a countertop area or a surface for folding clothes.

• Consider a hanging rod or retractable clothesline for drying delicate items.

• Add decorative trim or a backsplash to protect the walls behind utility or soaking sinks.

• Make your space functional and appealing with finishing touches like small rugs, wall hooks, wallpaper accents, and matching containers. 

Laundry Room Addition vs. Renovation

If your home already has a location that houses your laundry machines, you may choose to renovate it instead of building a new addition. While building a new addition means you can create almost any laundry room you can think of, renovating an existing one can cost far less and will take less time to accomplish, although you may not get the dream space you desire. The minimum cost for a full renovation is $1,300, while an addition starts at $5,000.

Tips to Reduce Cost While Adding a Laundry Room

Adding floor space to your home for a new laundry room is a significant investment. However, there are several ways to manage costs to help meet a budget. 

• Consider performing some of the finishing tasks yourself. Drywall, flooring, and tile installations are good as DIY projects.

• Discuss disposing of construction waste as a DIY project with your contractor as a way to reduce costs.

• Choose cost-effective materials for your flooring, countertop, and cabinetry. 

• Reuse your old laundry machines in the new space instead of purchasing new ones. 

Does A Laundry Room Addition Increase Home Value?

A laundry room addition can have a return on investment (ROI) of between 60% and 70% of the project cost. Meaning if your addition costs $15,000, you can expect an increased home value of between $9,000 and $10,500, or an average of 3.25% on a $300,000 home. The most popular reason to install a laundry room addition is for your own convenience and comfort rather than as an investment in the house itself.

However, experts disagree on the ROI amounts. The difference in value depends on the market in your area and what buyers are looking for. In many areas, having laundry machines in a basement, hallway, or closet is enough for most buyers. However, in areas where larger homes are the norm, a designated laundry room is often expected.
