24×36 Three-Car Garage
Three full bays across a 36-foot front — 864 square feet for three vehicles, or two vehicles and a workshop bay that's finally separate from where the cars live.

Site-built in Connecticut
How much does a three-car garage cost in Connecticut? As with any garage, there are two numbers: the structure and the complete project. Thomas Construction's standardized 24×36 structure starts at $99,362; foundation, site preparation, permitting and electrical are itemized in the turnkey planning estimate below. Three-car garages put the doors on the long eave side, so the building presents a wide, house-like face — and needs a wider stretch of level ground than a two-car footprint.

Concept floor plan
Three 9-foot doors along the 36-foot eave side, a gable-end entry door, and a clear-span interior that lets any bay become a shop.
Three bays change how the building works
A third bay isn't just one more parking space — it's the flexibility that makes the whole garage calmer. The most common layouts we build:
- Three vehicles: two daily drivers plus the third car, the winter car, or the one you're keeping for a kid in college.
- Two vehicles + workshop bay: the end bay becomes a dedicated shop with its own door — sawdust and projects never touch the cars.
- Two vehicles + equipment bay: tractor, trailer, or the gear a larger property accumulates, behind its own door instead of under a tarp.
On the 24×36 the three 9-foot doors face the 36-foot side, which means the driveway approaches the long face of the building. It reads like a carriage house from the street — and it's the reason this footprint wants a wider, flatter building site than the two-car models.
Ideal for
- Three vehicles
- Two cars plus a dedicated workshop
- Collector overflow
- Tractors, trailers and equipment
- Larger properties
Serious about wrenching rather than parking? The 30×36 Lift adds width, depth and lift-ready height to this three-bay format.

What affects the final cost?
Two 24×36 garages can carry different price tags for reasons that have nothing to do with the building. The site drives it:
- Access — can excavators and concrete trucks reach the building site, or does material move by smaller machine?
- Grade — a sloped site needs cut, fill and retaining that a flat lot doesn't.
- Soils & ledge — Connecticut ledge is real; rock changes excavation.
- Drainage — water management protects the slab and the neighbors, and towns increasingly require it.
- Utilities — distance from your panel to the garage sets trenching and wire costs.
- Town requirements — setbacks, wetlands review and engineering vary town to town.
- Options — doors, dormers, storage trusses and finishes move the number in plain sight.
Foundation type and depth are a big part of this — here is how garage foundations are priced in Connecticut. This is why every published figure is a planning estimate. After a site visit, your written proposal carries firm numbers for your property — and here's how to compare them fairly against any other quote.

24×36 FAQs
Questions about this model
Structure pricing starts at $99,362, with foundation, site work, permits and electrical itemized separately in the planning breakdown above. A three-car project involves more concrete, roof and door hardware than a two-car — and usually more site grading, since the building needs a wider level pad. A site visit turns those variables into a firm written number.
That's the most popular way to use this model. The clear-span interior means no posts between bays, so the end bay takes a workbench wall, machine tools and its own circuits. Insulating and heating just the shop end is a common option we can design in.
It needs a wider approach, since the doors span roughly 31 feet of the front face. We look at driveway geometry, turning radius and slope during the site visit — often the driveway work is modest, but it belongs in the plan (and the budget) from day one.
Yes. Attic trusses give the full 36-foot length usable storage above. A structural second floor or garage apartment is also possible and moves the project into our custom design-build work.
It depends on setbacks, lot coverage and septic locations, which vary by town. An 864-square-foot accessory building is well within what most Connecticut residential zones allow, but we verify your specific lot against zoning before any design is finalized — that's part of our permitting service.
