2-Car vs. 3-Car Garage: The Storage That Matters

A two-car garage is the norm. About 65% of new single-family homes finished in 2024 had one, and 15% had three or more spaces. A third bay helps if you have a third car, a boat or a workshop, but garage storage and depth matter more to most buyers than the extra door.

What percentage of Americans have a 3 car garage?

Among new homes, about 15%. NAHB's analysis of Census data on new single-family homes completed in 2024 found:

Does a 3 car garage add value to a house?

It can, if buyers in your area want one. A third bay is useful for a third vehicle, a boat, a workshop, a gym or storage. In markets where most homes have two-car garages, a third bay can set a home apart.

It also costs more to build and needs a wider lot. If you won't use it, the money may do more elsewhere in the home.

How much does not having a garage devalue your house?

There's no reliable single figure. It depends on the market and what buyers expect. In areas where nearly every comparable home has a garage, a home without one stands out, and not in a good way. Since about 89% of new homes in the 2024 data had a garage, it's a feature most buyers assume.

The storage that actually matters

What people regret skipping isn't usually the third bay. It's storage:

• Garage storage. NAHB's 2024 survey found 81% of buyers rate it essential or desirable.
• Garage depth. A few extra feet makes room for a full-size truck plus a workbench or shelving. Measure your vehicles.
• Attic access and decking. Ask whether attic space is usable for storage.
• A walk-in pantry and closets. Also high on buyers' lists.
• Outlets in the garage. For a freezer, tools or a future EV charger. Easier to add during the build.

What to check

• Will my vehicles fit with the doors open and room to walk around?
• Is there space for shelving, bikes and trash bins?
• Are there enough outlets, and is there a circuit for a charger later?
• Is a garage extension or a third bay offered on this plan and lot?
