How Much Does a Mudroom Addition Cost? [2024 Data]

Size of Mudroom Addition

The size of your mudroom is the most significant cost factor of the project. However, mudrooms are relatively small, 120 square feet or less, so the total cost will be lower than if you were adding a large primary suite or a dining room addition. You’ll also pay less to convert an existing space to a mudroom than you would to build a new area.

General Contractor Costs

If you’re adding a bump-out—creating a room by removing a wall to build a new space—or building walls in a garage to create a mudroom, you’ll need to hire a home addition contractor near you to handle the renovations. They’ll be able to properly frame the room, install the foundation and roofing, and finish the room with drywall and siding. Contractors often charge 10% to 20% of the project's total cost. So if your mudroom addition costs $12,000, the contractor fees will be between $1,200 and $2,400.  

Here is the work your contractor will handle for your mudroom addition:

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

• Framing: $6–$10 per square foot

• Roofing: $2–$3 per square foot

• Siding: $3–$12 per square foot

• Foundation: $6–$12 per square foot

• Flooring: $3–$25 per square foot

Additional Cost Factors

Even though a mudroom is relatively small, there are several additional factors you should consider when estimating the project’s cost. Ultimately, how much it costs to build a mudroom will depend on certain factors, including the cost of permits and post-construction clean-up,  finishes, and painting, among a few other things.

Permits

You’ll likely need building permits if you’re framing out a new mudroom in an existing living space, and you’ll definitely need them if you’re having a professional build a mudroom bump-out on your home.

Building permits vary widely depending on your location and your local building department, but permits for mudrooms will cost between $125 and $3,000, with an average cost of $1,250.

Foundation and Exterior Building Materials

Building a new foundation for your mudroom will cost $9,000 to $15,000 extra. This premium is because foundations require excavation, ground preparation and compacting, mold construction, concrete delivery, and concrete pouring. 

Plumbing and Electrical Work

Your mudroom will require electrical work, and you may even want to opt for plumbing, too. Here are some of those common costs.

• Installing a light fixture: $70–$300

• Installing a light switch: $100–$202

• Installing an outlet: $120–$300

• Installing a sink: $450

• Replacing pipes: $1,250

Post-Construction Clean Up

Some contractors may not include a clean-up after they complete the construction, so you may need to pay more for this service. This could include removing excess building materials, returning your yard to its former status if you have a new mudroom foundation poured, or creating a smooth transition between your mudroom and your living space.

Depending on the work you need done, a clean-up service could cost between $100 and $1,000. Keep in mind that some contractors may include some of these line items in their original estimates. You can also ask your contractor if you can do the clean up on your own to save some money on the final cost.

Built-In Storage

What is a mudroom without built-in storage? If you really want to get your space looking professional, clean, and organized, you might want to consider built-in storage, like cabinets, drawers, or shelving.

If you decide on DIY mudroom lockers, you could save some money on labor and spend around $500 for a professional-looking set-up. Having the same work done by your mudroom expert could cost between $1,000 and $1,250.

Flooring

If there’s one area you don’t want to skimp on when building an entryway into your home, it’s the mudroom flooring. The floors in your mudroom will see a lot of foot traffic, rain, snow, leaves, dirt, sand, and more. You could spend $100 installing simple vinyl tiles, but we recommend a more durable ceramic tile or vinyl plank floor. These will cost between $250 and $3,000, in most cases, depending on your mudroom dimensions.

Higher-quality, waterproof floors that are easy to clean will stand up to the use they’re sure to see in a mudroom, and they’ll make your cleaning protocol a whole lot easier.

Painting

The cost to paint a mudroom will depend on the size of the space and the complexity of the work, but the average cost will sit around $530 for a mudroom measuring 6 feet by 6 feet. You can expect to spend about $2.75 per square foot you need painted. Keep in mind that this total can be a bit lower than your total square footage, as built-in lockers and shiplap are common in mudrooms and can cover up portions that would otherwise need painting.

Fit and Finish

Finally, the finishing touches you want after the primary construction of your mudroom will play a major role in your costs. If you want to build custom mudroom lockers and built-in storage and fit the space with waterproof flooring and decor, your price will be much higher than if you just go with the basics.

Depending on your mudroom ideas and who does the work, you could pay between $300 and $7,500 to finish your mudroom according to your storage needs and personalized preferences.

Mudroom Customizations

Mudrooms are utilitarian in nature, serving as storage areas and a place to take off and put on shoes, boots, coats, and other outdoor wear without getting your living space dirty. However, lots of homeowners deck out their mudrooms to make them more visually appealing and add additional utility to the areas, making them the perfect drop zone for the house.

Below are some average costs for typical mudroom add-ons:

• Mudroom lockers: You can build custom mudroom lockers yourself for around $500, or a carpenter can build them for you for between $1,000 and $1,250, depending on the size. You can also purchase mudroom lockers for between $160 and $1,000 depending on the size and style.

• Mudroom cubbies: Small cubbies for kids or for boot and shoe storage are super affordable storage options, totaling around $150 to $250 for DIY construction or around $500 for a professional to make them.

• Standalone shelves: Shelving units can range from $25 to $150 each for materials if you install them yourself. A professional can install them for between $100 and $300 each.

• Built-in storage cabinets: Mudroom cabinets are great for storing holiday decorations and other storage items you use infrequently. You could build them yourself for around $150 to $300 per cabinet, or a pro can install them for between $300 and $600.

• Utility sink: A utility sink is a convenient place to wash dirt and mud off of items before they get put away. You can have a plumber install a utility sink for between $500 and $1,200.

• Laundry area: Many homeowners save interior space by coupling their mudrooms with their laundry rooms. You can get hookups for your washer and dryer installed for around $750, and a nice countertop for folding will cost between $100 and $400, depending on the material and size.

• Dog-washing station: A shower for your furry friend could be the best way to keep mud and dirt out of your home. You can expect to pay a plumber around $2,000 for this luxury add-on, including roughing in the plumbing.

DIY Building a Mudroom vs. Hiring a Pro

You can save between $500 and $7,000 by doing the work yourself. A DIY mudroom is feasible if you’re converting an existing closet or cabinet. Most homeowners can tackle building custom shelving and organizational equipment. Experienced DIYers could even frame out an area of their homes for a mudroom. 

However, if you want a dedicated home bump-out built for your mudroom, it’s best to hire a professional. They have the skills and tools to do the job to your liking—and on schedule.

Pro Tip

[For a home addition], we charge piece-by-piece for the project, then we add our profit and overhead. For example, lumber for the project, permits, demolition, electrical, plumbing, and drywall. I add them up and then add our profit and overhead. On smaller jobs, we work by the hour and then add the material on top of that.

Ways to Save Money on a Mudroom Addition

There are a few ways besides DIY to save money on your mudroom addition costs.

• Build inside an existing space. Building a mudroom in a garage, a screened-in porch, or an existing closet will cost $9,000 to $15,000 less than building a bump-out.

• Go small. Avoid oversizing your mudroom, as most mudroom additions cost between $100 and $200 per additional square foot. 

• Consider future expansions. If you want plumbing or electrical hookups for a laundry area, utility sink, or dog shower station, have the utilities roughed in now. You’ll spend money upfront but will save down the road by not having to demo and rebuild to add square footage.

• Don’t cut corners on flooring. It’s better to pay a premium for a high-quality, durable, waterproof floor. You’ll spend more upfront, but you won’t have to take the time or money to replace vinyl tiles that wear down more quickly over time.

Does a Mudroom Addition Increase Home Value?

Adding a mudroom increases the value of your home, but there are some exceptions. For the most part, adding a mudroom adds some additional utility to your property and helps protect interior building materials, especially your flooring, which can add value. 

However, in other cases, taking away living space to build a mudroom might not be beneficial from a property value perspective. If you build a mudroom in a garage, an existing closet, or a screened-in porch, though, your home value will almost certainly go up.
