Based on average costs from internet data. Actual costs in Middlesex County and Greater Boston, MA may vary.
Adding a laundry room is one of the most practical home improvements you can make. According to the National Association of Home Builders, a dedicated laundry room is the most common feature buyers want in a home. And in suburban Massachusetts — whether you’re in Billerica, Chelmsford, or Lexington — that demand is real.
But knowing where to start with budgeting is tough. Costs shift dramatically based on your home’s layout, how far utilities need to travel, and the materials you choose. A project that looks simple on paper can get complicated fast once permits, plumbing, and framing enter the picture.
This guide breaks down every cost component — from permits and foundation work to cabinetry and appliances — so you can plan your project with confidence.
Cost of adding a laundry room terms to know:
The Total Cost of Adding a Laundry Room in 2026
When planning to build a completely new space for your washing machine and dryer, you are looking at a project that combines structural construction with complex utility installation. According to average costs from internet data, the cost of adding a laundry room typically hovers around $15,000 for a standard build. However, because home additions vary wildly based on structural needs, the actual price can span a wide range from $5,000 to $150,000.
If you are building a simple bump-out on an existing deck or concrete pad, your expenses will sit comfortably on the lower end. But if you are building a multi-story addition or a luxury main-floor mudroom-laundry combo that requires extensive excavation, foundation pouring, and structural tying, the costs can scale up to $150,000.
When you evaluate what does adding square footage to your house actually cost, you have to look beyond the drywall. You are paying for a micro-addition that must pack heavy plumbing, high-voltage electrical, dedicated HVAC venting, and moisture-resistant structural elements into a relatively compact footprint.
Average Cost of Adding a Laundry Room by Square Footage
The cost of a home addition is often calculated on a square-foot basis. For a standard laundry room addition, homeowners spend an average of $250 per square foot based on internet data, though this rate typically ranges from $140 to $300 per square foot depending on structural complexity and finishes.
Interestingly, the cost per square foot is not perfectly linear. Smaller additions often carry a higher cost per square foot because the expensive “core” elements—like the plumbing hookups, 240V electrical lines, and ventilation—must be installed regardless of whether the room is 35 or 100 square feet. You can learn more about managing these calculations in our guide on how to calculate your addition cost like a pro.
Here is how average costs based on internet data break down by common laundry room sizes:
- 35 Square Feet (Small / Closet Style): Typically costing $5,000 to $11,000. This size is perfect for a stackable washer and dryer set with a small folding counter or storage cabinet. It is often built as a small bump-out or by reclaiming space from an adjacent garage or hallway.
- 60 Square Feet (Medium / Dedicated Room): Typically costing $9,000 to $18,000. This footprint allows for side-by-side appliances, a built-in utility sink, several linear feet of cabinetry, and a dedicated hanging rod for air-drying clothes.
- 100 Square Feet (Large / Multi-Functional Mudroom): Typically costing $14,000 to $30,000 (and up to $150,000 for high-end exterior builds). This size provides ample space for a combined laundry and mudroom, complete with custom cubbies, bench seating, pet washing stations, and premium quartz countertops.
Comparing a Laundry Room Addition to a Remodel
If you already have a laundry room but it feels cramped, dark, or outdated, you might be debating whether to remodel the existing space or build an entirely new addition.
According to average costs from internet data, a standard laundry room renovation averages $8,100, but projects can range from $1,300 to $85,000 for ultra-luxury custom overhauls. A simple cosmetic refresh (new paint, stock cabinets, and luxury vinyl plank flooring) sits at the lower end, while relocating plumbing lines across the house to create a new layout drives the budget to the higher end.
Here is a quick comparison to help you weigh your options:
| Feature | Laundry Room Remodel / Renovation | Laundry Room Addition |
|---|---|---|
| Average Cost Range | $1,300 – $85,000 (Based on internet data) | $5,000 – $150,000 (Based on internet data) |
| Space Impact | Uses existing square footage; may sacrifice a closet or bathroom space. | Adds brand-new square footage to your home’s footprint. |
| Plumbing & Electrical | Often utilizes existing hookups (unless relocating). | Requires entirely new utility lines run from the main stack. |
| Construction Time | 1 to 4 weeks | 4 to 8+ weeks |
| Typical ROI | 60% – 80% | 60% – 70% |
| Best For | Budget-conscious homeowners with underutilized space. | Homes with zero extra interior space that need a functional layout. |

Breakdown of Construction and Utility Installation Costs
Building a brand-new room from the ground up requires coordinating several distinct phases of construction. For a seamless project, homeowners typically hire a general contractor to oversee the framing, roofing, plumbing, and electrical work. Understanding these phases helps you see where every dollar goes. For a broader look at structural pricing, review our house addition cost complete guide.
Preparation, Permits, and Design Fees
Before a single board is framed, you must invest in the planning and legal approval phases. In Massachusetts, particularly within Middlesex County, building codes are strict regarding structural safety, electrical loads, and plumbing drainage.
According to average costs from internet data, preparation fees typically include:
- Building Permits: $150 to $2,000. Municipalities like Billerica, Chelmsford, and Reading base permit fees on the projected cost of the project.
- Architectural Design: $550 to $2,200. An architect ensures the new addition matches your home’s existing aesthetic and structurally ties in safely.
- Structural Engineering: $350 to $800. If you are cutting into exterior load-bearing walls to connect the new room, an engineer must calculate the size of the header beam required.
- Interior Designer: $200 to $2,100. Helpful for maximizing storage, lighting, and cabinet layouts in tight spaces.
Planning these initial steps carefully prevents expensive changes mid-construction. Our guide on budgeting for your Bay State build offers excellent strategies for navigating local permit and design fees.
Foundation, Framing, and Exterior Construction
If you are building an exterior addition (building “out” rather than converting an existing interior room), you must construct the structural envelope.
Based on average internet data, expect the following structural cost breakdowns:
- Foundation: $1,200 to $4,000. This includes excavation and pouring a concrete slab or installing frost-protected piers.
- Framing: $500 to $1,600. Constructing the wood skeleton of the walls and roof.
- Siding: $600 to $3,000. Matching your home’s existing exterior (vinyl, wood clapboard, or fiber cement).
- Insulation: $150 to $400. Crucial in Massachusetts to prevent pipes from freezing during harsh New England winters.
- Roofing: $400 to $1,300. Tying the new roofline into your existing shingles.

Plumbing, Electrical, and HVAC Utility Costs
The heart of any laundry room lies in its utilities. This is where a significant portion of your budget is spent, especially if your new room is far from your home’s main water and electrical panels.
According to average internet data, utility installations break down as follows:
- Plumbing Rough-In: $1,500 to $4,500. This involves running hot and cold water supply lines, installing a 2-inch drain line with a proper trap, and hooking up a utility sink if desired. Licensed plumbers typically charge $45 to $200 per hour.
- Electrical Work: $1,200 to $3,500. Washers require a standard 120V circuit, while traditional electric dryers require a dedicated 240V outlet. Licensed electricians charge $40 to $120 per hour. If your home’s main panel is fully loaded, upgrading your electrical panel can add $2,000 to $5,000.
- HVAC and Venting: $300 to $2,500. Dryers must be vented directly to the outdoors using rigid metal ductwork. Keeping this run short and straight is essential for safety and efficiency. If you want to tie the room into your home’s heating and cooling system, an HVAC technician (charging $50 to $150 per hour) will need to run ductwork.

Finishing and Appliance Costs for Your New Space
Once the structural shell is built and the utility lines are inspected, it is time to focus on the elements you will see and interact with every day. The finishes and appliances you choose will define the room’s aesthetic and daily usability. For details on how finishing labor impacts home value in our region, review our analysis on breaking down the average cost of home addition in Massachusetts.
Drywall, Flooring, and Cabinetry Finishes
The materials used in a laundry room must be highly durable and water-resistant. Damp clothes, occasional spills, and high humidity from dryers mean that cheap materials will degrade quickly.
According to average internet data, finishes scale with the size and quality tier of your project:
- Drywall and Paint: Drywall installation runs $1.50 to $3 per square foot, while premium moisture-resistant paint adds $35 to $60 per gallon.
- Flooring: $200 to $3,500. Sheet vinyl is the most budget-friendly ($200 to $600 installed), while Luxury Vinyl Plank (LVP) offers excellent waterproof durability for $800 to $2,000. Ceramic or porcelain tile provides the best long-term protection against major leaks, costing $600 to $1,500.
- Cabinetry: $250 to $5,000+. Pre-assembled or Ready-to-Assemble (RTA) stock cabinets cost $800 to $2,500 installed, while custom floor-to-ceiling built-ins can easily exceed $5,000.
- Countertops: $300 to $1,400. Laminate is cost-effective, but quartz or solid-surface remnants are highly popular for their stain resistance and ease of cleaning.

Washer, Dryer, and Appliance Selection
Your choice of appliances will influence both your upfront budget and the physical layout of the room.
According to average costs from internet data, appliances run:
- Entry-Level Sets: $1,200 to $1,800. These are typically top-load washers and matching electric dryers with basic dial controls.
- Mid-Range Sets: $2,500 to $4,000. High-efficiency front-load or smart stackable units with steam cycles and larger capacities.
- Premium / Specialty Sets: $5,000+. Ultra-quiet, large-capacity smart appliances or ventless heat pump dryers.
Ventless heat pump dryers are growing rapidly in popularity. While they cost $1,200 to $2,500 more upfront, they use up to 50% less energy and eliminate the need to cut a dryer vent hole through your exterior siding.

Frequently Asked Questions About Laundry Room Additions
What is the typical ROI for a laundry room addition?
According to real estate data, a dedicated laundry room addition offers a 60% to 70% return on investment (ROI). Beyond the monetary return, it significantly boosts your home’s marketability. A well-designed, main-floor laundry room makes a home feel highly organized and modern, often helping homes sell several days faster in competitive markets like Greater Boston.
Do I need a permit to add a laundry room in Massachusetts?
Yes, absolutely. Because adding a laundry room involves structural modifications, running new plumbing lines, and installing high-voltage electrical circuits, you will need building, plumbing, and electrical permits. In towns like Billerica, Chelmsford, and Tewksbury, failing to pull proper permits can result in heavy fines, failed home inspections when you try to sell, and potential insurance denials if a leak or fire occurs.
Professional Labor vs. DIY Cost of Adding a Laundry Room
While tackling finishing tasks like painting, installing cabinet hardware, or laying down snap-together LVP flooring is highly feasible for a handy homeowner, the core structural and utility work should always be left to licensed professionals.
Plumbing leaks can cause thousands of dollars in structural rot, and improper 240V electrical wiring poses severe fire hazards. Hiring a licensed general contractor ensures that your project is structurally sound, built to current Massachusetts building codes, and backed by a professional warranty.
