How wide should a two-car metal garage be?

20 feet is the practical minimum for two cars. 24 feet gives you room to open doors fully and store items along the walls.

One wide door or two single doors?

Two single doors keep the frame stronger at the center and let you open one bay at a time. A single 16-foot door makes parking easier for larger vehicles.

Do I need a permit for a 20x25 garage?

Most counties require a permit for a detached garage of this size. Omega can supply engineered drawings to support your application.

Two-Car Garage

20x25x9 Two-Car Garage

The 20x25 is the entry point for two-car metal garages. Two side-by-side roll-up doors let each vehicle come and go independently, and the footprint stays small enough for most suburban lots and setback requirements.

Priced for your address and local wind and snow requirements. Usually by 9am next business day.
