How Much Does a Custom Garage Cost in Massachusetts? (2026 Pricing Guide)

A single-level garage is the straightforward one: parking below, clean roofline, no loft or second floor. Available in 1 to 4-car configurations. We build them at 6/12 or 9/12 pitch depending on the look you want and what the lot calls for.

Starting price: $38,095 (T1-11 siding, 8-foot walls, 6/12 pitch, 20×20 footprint). Prices below are from the 2026 price book — Common Truss, 8-foot walls, 6/12 pitch, T1-11 siding. A 20×20 is tight for two cars but workable. A 24×24 is the practical two-car standard. A 32×32 or larger handles three cars or a serious workshop layout.

Prices are from the 2026 Hometown Structures price book and cover the garage structure only. Excavation and concrete foundation are additional — a required cost for every project. Verify final pricing with your salesperson.

Vinyl siding typically adds $1,500–$3,000+ to the base price depending on size. T1-11 (LP SmartSide) is a solid choice and holds up well in New England. If you want zero maintenance, vinyl is worth the step up. Use the Garage Pricing Calculator to configure your exact options — size, wall height, pitch, and siding — and see the current price-book number in real time.

Stepping up to 9/12 pitch, 10-foot walls, or 12-foot walls each add to the base price. Taller walls matter for large trucks, RVs, or car lifts. See the single-level garage page for configuration details.

A story-and-a-half uses room-in-attic trusses — a different truss design that opens up loft space above the bays. The loft runs the full length of the garage at about half the width. No dormers: the bonus space is created by the truss geometry, not by punching holes in the roof. At a 9/12 pitch you get a practical loft; at 12/12 the pitch is steep enough for even more headroom up there.

Starting price: $47,770 (T1-11 siding, 8-foot walls, 9/12 pitch, 20×20 footprint). Prices below are from the 2026 price book — Attic Truss, 8-foot walls, 9/12 pitch, T1-11 siding. The loft math: a 24×36 footprint gives you about 12×36 feet of usable space upstairs. A 28×40 gives proportionally more.

Who builds a story-and-a-half: typically someone who needs dedicated workshop or hobby space above the cars, doesn't want to commit to the full square footage and cost of a two-story, and is comfortable with a half-width upper level rather than a full floor. It's the practical middle ground.

See the story-and-a-half garage page for details.

A two-story garage has a full second floor with real ceiling height throughout. The way you get there: shed dormers on both sides of the roof. The dormers extend the roofline out on both eave sides, converting what would be attic space into actual rooms. They're not an upgrade or an add-on option — they're built into the design. That's how a two-story garage works.

Starting price: $58,235 (T1-11 siding, 12-foot walls, 12/12 pitch, 20×20 footprint). Prices below are from the 2026 price book — Attic Truss, 12-foot walls, 12/12 pitch, T1-11 siding. Shed dormers on both sides are included in the two-story design; they are what creates the full second floor.

Who builds a two-story: typically someone who needs a dedicated living or working space above the garage — a home office, a rental apartment, a full studio, a gym. The upper level is a real floor with room to design around. If you're just looking for storage or workshop overflow, a story-and-a-half usually gets you there at a lower cost.

See the two-story garage page for details.

The from prices above are the starting point. Here's what moves the number from there.

Size. The single biggest factor. Larger footprints cost more — more framing, more siding, more roofing. Every footprint from 20×20 up to 40×80 is available. The calculator at /garages/pricing shows specific pricing by size.

Wall height. Standard is 8 feet. Stepping up to 10 or 12-foot walls adds framing material and siding throughout. Taller walls matter if you're storing a large truck, RV, or heavy equipment, or if you're planning a car lift.

Roof pitch. Steeper pitches add material and complexity. A 9/12 pitch costs more than a 6/12. A 12/12 costs more than a 9/12. It affects headroom in the loft (for story-and-a-half), aesthetics from the street, and snow shed behavior.

Siding. T1-11 (LP SmartSide) is the standard and the most affordable. Vinyl adds cost upfront but eliminates painting over the life of the building. Other options — shiplap, board and batten, HardiPlank, cedar clapboard, cedar shakes — are available at varying premiums.

Doors, windows, and options. Overhead garage doors, walk-in entry doors, windows — all added individually. The base price includes a shell. Everything you add goes on top.

Excavation and foundation. Not included in the garage price — and this one matters. Every garage requires a concrete foundation. Not optional, not a nice-to-have: required. A detached garage in Massachusetts needs a frost-protected foundation — typically a concrete stem wall with footer that goes below the 48-inch frost line — plus the excavation to get there. These are real costs that belong in your budget from the start. Foundation cost is site-specific: it depends on soil conditions, excavation requirements, lot access, and concrete pricing in your area. Hometown Structures provides excavation and foundation work, or you can hire your own concrete contractor — either way, plan for it as a separate line item. We cover the details in our post on frost-protected foundations for accessory structures in Massachusetts.

The short version: not as much as you might expect. Prefab garage companies (wall panels built in a factory, trucked to your site) sometimes advertise speed and competitive pricing. The tradeoff is fit — prefab walls are built to a spec sheet, not your actual foundation. When the foundation isn't perfect (common in New England), adjustments happen on-site at your expense.

Site-built framing means the walls are cut to match your actual slab, not a drawing from six weeks earlier. The fit is exact. There are no transport-size constraints on wall height or single-span dimensions. And when something needs attention afterward, we're Massachusetts-based — not a crew driving back from Pennsylvania.

Yes — these are from the 2026 Hometown Structures price book. They reflect T1-11 siding, standard 8-foot walls, and the smallest available footprint for each garage type.

The final price for your project will be different. It depends on your chosen footprint, wall height, pitch, siding, doors, windows, and options. None of those are included in the from price.

The fastest way to get a real number: use the garage pricing calculator. It lets you select your footprint, wall height, pitch, and siding, and shows the price from the current price book in real time.
