For a room that’s rarely bigger than 6ร8 feet, a mudroom changes how a New England house works more than almost anything else you can build. Boots, coats, backpacks, the dog towel, the wet mitten season that runs October through April โ it all needs somewhere to land that isn’t the kitchen floor. Here’s where mudrooms come from in an existing house, what they cost, and the features that separate the ones that work from the ones that just collect piles.
Three Ways to Get One
1. Convert Space You Already Have โ $5,000 to $20,000
The entry from the garage, a back hall, a corner of an oversized laundry room, the rarely-used formal entry: most houses hide a mudroom somewhere. The project is built-ins, durable flooring, lighting and paint โ no foundation, no roof, the fastest payoff in the list.
2. Capture a Slice of the Garage โ $15,000 to $35,000
Framing off the last 6โ8 feet of a deep garage bay creates a real, heated mudroom between car and kitchen. Insulation and heat are what make it a room instead of a closet; most two-car garages can give up the space without giving up the cars.
3. The Bump-Out Addition โ $25,000 to $60,000+
When the floor plan truly has nothing to give, a small addition at the side or back door builds exactly the room you want โ and it’s the most common small addition we’re asked about. Pairing it with a project already underway (siding, a deck, a kitchen on that wall) shares the mobilization costs.

What Makes a Mudroom Actually Work
- A seat. Boots come off sitting down. A bench with cubbies under it is the non-negotiable core.
- One cubby per person, plus guests. Open cubbies get used; cabinet doors hide chaos until they can’t close. Hooks at two heights if there are kids.
- Floors that shrug off water and salt. Porcelain tile and LVP are the champions โ see the flooring cost guide. A floor drain is a luxury worth having in a garage-side mudroom.
- The upgrades that earn their keep: a utility sink for dog paws and paint brushes, an outlet inside a cubby for charging, and a closet rod for snow pants drying season.

Frequently Asked Questions
Does a mudroom add resale value?
In New England, yes โ buyers here know exactly what February looks like, and a real mudroom photographs and shows like the practical luxury it is. It won’t return like a kitchen, but small money in usually means strong value out; the broader ranking is in which projects add value.
Can the mudroom share space with laundry?
It’s the classic pairing โ wet things arrive where the washer lives. The design detail that matters: enough room that a laundry basket and a kid taking off boots can coexist, which means 8 feet of width instead of 6 makes all the difference.
