Three Car Garages

Three bays wide — a garage that finally keeps up.

There's a point where two bays stop being enough — a third vehicle, a boat that lives on its trailer, a work truck that pays the bills, a hobby that's outgrown the corner. A three-car garage is the build that stops the overflow, and at 26 to 30 feet wide it's a genuine step up in engineering, not just a wider version of a double: the frame moves to heavier triple-truss construction to clear the span without a post in the middle.

Thirty feet wide fits three full-size trucks; twenty-six fits three cars or two vehicles plus a real workshop. Add depth — 30 or 40 feet long — and you've got room for a lift, a bench wall, and storage the house will never miss. Fully enclosed, lockable, and certified to your county's wind and snow loads. One permitted roof over the whole operation.

The three-car lineup

Three-bay garages, built to your plan.

Set the width and depth, place two or three doors, wall off a workshop, raise the eave for trucks or a lift, then pick your colors. Every one is engineered and built to spec.

Planning a lift, a shop, or a fourth bay?

Three-car builds are where custom really pays off. Design the exact footprint and door layout, or talk through the plan with a building specialist who'll spec the frame and certification for you.

How three bays get used

One roof, three jobs at once.

Nobody buys a three-car garage just to park three cars. The reason it earns its footprint is that it does several things at the same time — and keeps them all locked and dry.

01
The fleet, off the street

Work truck, personal vehicle, and the trailer or van — a tradesperson's whole operation parked, secured, and permitted under one roof.

02
Boat down one bay, cars beside it

The left or center bay runs deep enough for a boat on the trailer; the other two keep the daily drivers. No marina fees, no tarp.

03
Vehicles + a walled-off shop

Frame an interior wall and turn one bay into a finished workshop, studio, or office while two bays stay parking.

04
The collector's garage

Room for a two-post lift, a rolling tool box the size of a dresser, and the cars that earned the space. Insulate it and work year-round.

05
Home-business headquarters

Inventory, a work vehicle, and a bench — a permitted, insurable base of operations that isn't eating your driveway.

06
Everything, finally in one place

Cars, mowers, the side-by-side, the seasonal gear — the build that ends the 'where does this go' problem for good.

Plan the layout

Three widths, three very different garages.

At this size the width you pick changes what the building is for. Match it to the vehicles and the work — and remember depth is the cheap way to add a workshop.

01

26 ft wide

Three mid-size cars across, or two vehicles plus a genuine workshop bay. The entry to true three-car and the value pick.

02

30 ft wide

Three full-size trucks with room to open doors — the width serious fleets and big-vehicle owners want.

03

Go deep, not just wide

30 or 40 ft of length adds a lift bay, a bench wall, or storage for a fraction of what widening costs. Depth is the smart upgrade.

04

Vertical roof, by default

At these widths a vertical roof isn't an upsell — the long panel runs need ridge-to-eave shedding to stay watertight and carry snow. We'll spec it in.

Sizes & prices

How big is a three-car garage?

A three-car steel garage starts at 26 feet wide and runs to 30 ft and beyond. 26 ft fits three cars; 30 ft is what three full-size trucks need. Above that you're into four-car and commercial territory.

Depth is where the workshop lives — 30 ft is three across, 40 ft adds a lift or bench bay behind them. Search or scroll the three-bay sizes below and hover any one to see what it holds, its SKU, and its price.

These are heavier, triple-truss builds, so they're engineered and quoted individually — the size below is your starting point, not a ceiling.

Delivery & installation, included

Engineered, delivered, and erected by our crew.

A three-car build is heavier steel and a wider clear span, so it's engineered to your loads and installed by our crew on your prepared, level site. A poured slab is required for a build this size — it carries the frame, seals the doors, and takes the certified concrete anchors. We handle the raise; you handle picking the spot.

  • Anchors for concrete, asphalt, or ground — included
  • Certified builds: engineer-stamped for your county's wind & snow loads
  • 12- or 14-gauge galvanized steel — carries our 20-year rust warranty
  • Factory-direct pricing with no middleman markup

We are building a barndominium and they delivered the shell on schedule. Our contractor said the framing was straighter than most stick-built shells he sees.

Loafing shed for the horses showed up exactly when they said it would. The crew leveled and anchored on uneven ground and didn't try to charge extra.

Hurricane-rated anchors and engineer-stamped drawings were ready when our county asked. Permit went through the first time.
