Considering Building Your Own Garage? Find Out How

Garage Width Considerations

If you are building your own garage, there are some specific clearances that must be met in order for the garage door to run smoothly and function properly. The first of these is that the garage’s opening width should be smaller than the width of the door. The easiest way to accomplish this is to make your unfinished opening the width of the desired garage door, because once you install fascia board, you’ll have that needed edge for the door to seal on. Wooden doors are nearly always custom made, so you will be able to get the right fit regardless of your opening.

Garage Height Considerations

Most standard residential doors need 12” from the top of the door to the ceiling so that the door can go up and around the top without scraping the ceiling. Add 2” to this if you plan to install an operator. Want a lower clearance? Hardware exists that allows you to have clearance as low as 4” from the top of the door to the ceiling.

Side clearances should be at least 6” wide from the floor to at least 12” past the top of the opening. It’s always good to have a solid header or at least a solid center plate to which the torsion spring and the operator mount can be fastened. All the interior framing must be flush. 110 power for the operator should be supplied about 30” back and approximate 8” offset from the center. If the plan is to insulate and drywall the interior of the garage, you may want to run some low voltage wires behind the framing up each side about 6” from the ground and to where the power is for the photo sensors, leaving plenty of slack for movement and for the wall switch.
