What Is the Average Cost of Building a Mudroom?

A well-built mudroom protects your floors, organizes your entryway, and gives your home a cleaner, more practical flow. For a 50-square-foot mudroom addition in Illinois, the average cost lands between $6,000 and $15,000. Most homeowners spend around $10,500 for a design that includes essentials like custom cabinets, moisture-resistant flooring, and good lighting.

At Complete Closet Design, we create custom mudroom solutions that actually fit your family’s routines, not just what looks good in a catalog. Whether you’re working with a blank wall or building out a new structure near the garage, our team builds smart entry spaces that look good and work hard.

Here’s a closer look at what shapes your mudroom budget and what’s usually included in that number.

What's Included in Your Mudroom Cost Breakdown

When planning your mudroom project, knowing what's typically covered helps you budget accurately and avoid surprises. Here's what most contractors include in their pricing:

• Building materials and hardware: Lumber, trim, drawer fronts, fasteners, and everything that brings the design to life.
• Labor and installation: Skilled work from licensed pros who handle framing, finishes, and built-in features.
• Built-in storage: Lockers, open shelves, or cabinets designed to take daily use from shoes, backpacks, and coats.
• Flooring installation: Durable, waterproof flooring that stands up to wet shoes and muddy conditions.
• Electrical work: Adding proper lighting and outlets for functionality.
• Paint and wall finishes: Weather-resistant materials that complement your home's style.
• Basic plumbing: If you're including a utility sink or connecting to an adjacent bathroom or laundry room.

The average price for these components can vary depending on your chosen materials and the complexity of your design. A closet conversion project typically costs less than building a new addition since you're working with existing space.

Factors That Shape Your Mudroom Budget

Every choice you make impacts the total cost to add a mudroom. From where you live to how large the space is, here’s what really matters when building out this kind of project.

Location Makes a Difference

In the Chicago area, labor costs run higher than the national average. Most general contractors charge $75 to $150 an hour. That’s partly due to higher demand, and partly due to tougher local building requirements. Permits alone for a mudroom addition can cost anywhere from $500 to $1,500, depending on your project scope.

Size and Square Footage Considerations

The cost per square foot for mudroom construction typically ranges from $120–$300. Here's how size affects pricing:

• Small mudroom (25–40 sq ft): $3,000-12,000.
• Medium mudroom (40–60 sq ft): $4,800-18,000.
• Large mudroom (60–100 sq ft): $7,200-30,000.

Larger mudrooms often offer better value overall, since fixed costs like permits and prep work are spread across more space. You get more out of your investment when you build with that in mind.

Existing Space vs. New Construction

Using part of your garage or reworking space near an existing entry will usually cost a lot less than building a new room from the ground up. Converting a closet, for example, might cost between $3,000 and $8,000. If you’re building a new structure that needs a foundation, expect a range of $15,000 to $30,000. For many homeowners, making use of existing space offers a good balance between cost, speed, and function.

Material Selection Impact

Your choice of building materials dramatically affects the final price:

• Economy materials: Basic open shelving, vinyl flooring, and standard hardware ($50–80 per sq ft).
• Mid-range options: Built-in benches, custom cabinetry, tile flooring, and solid finishes ($80–150 per sq ft).
• Premium selections: Hardwood cabinets, stone details, heated floors, and upscale finishes ($150–300 per sq ft).

Labor vs. DIY Considerations

Some homeowners take the DIY route to save money, but others prefer to hire professionals who get the job done right the first time. Doing it yourself could save up to half the labor cost, but there are trade-offs to keep in mind:

• Framing and structural work requires expertise.
• Electrical and plumbing need licensed professionals.
• Custom storage maximizes every inch of mudroom space.
• Professional finishing touches create a polished look.

Additional Cost Factors

Beyond basic construction, these elements can increase your investment:

• Special storage features: Built-in drawers, pet wash stations, or tech-friendly charging spots ($500–2,000).
• Windows and doors: Bring in natural light or create separate outdoor access ($800–3,000).
• HVAC work: Extending your home’s heating and cooling system into the new space ($1,000–3,000).
• High-end finishes: Designer lighting, upgraded hardware, or custom trim work ($1,000–5,000).

Sample Cost Breakdown: 60 Square Foot Mudroom Addition

Here's a real-world example of costs for a medium-sized mudroom project in Chicagoland:

This estimate assumes you’re building a brand-new addition next to your home. If you're converting a closet or garage space instead, your cost to build a mudroom will likely be much lower since you're not starting from zero.

Smart Budgeting for Your Mudroom Project

Planning your mudroom budget requires balancing immediate needs with long-term value. These strategies help you create a realistic financial plan:

• Start with what matters most: Prioritize everyday features like hooks, shoe storage, and easy-access shelving.
• Break it into phases: Focus on the essentials now and save the extras for a later upgrade.
• Shop around: Always get at least three quotes so you understand your price options.
• Set aside a cushion: Reserve 10–20% of your budget for surprise costs, especially if your home is older.
• Time it right: Building during off-peak seasons like late fall or winter may get you better contractor pricing.
• Look into financing: Home equity loans or lines of credit can help fund projects that add real value to your property.
• Think about resale: A good mudroom can return 70–80% of its cost when it’s time to sell your home.

The upfront investment in solid construction and smart materials pays off long-term, giving your family a space that looks great and holds up for years.
