How to Build a Garage Ceiling Shelf

What You'll Need
2-by-4 inch lumber
Circular saw
12 corner braces, each 5 inches long
Stud finder
Tape measure

A garage ceiling shelf can offer extra storage in your garage. More importantly, it can do achieve this without cluttering up much-needed space on the wall or ground. You can accomplish this project with a minimum of carpentry skills and a few hours of spare time.

Step 1 - Determine the Size of Your Garage Ceiling Shelf

Decide on the size of your garage ceiling shelf. It should be no more than 6 feet long and 2 feet wide. You don't want it to become too heavy and unwieldy.

You also need to decide how far below the ceiling it will hang. Determine this by your own height and the height of the vehicle that you keep in the garage. It should not be more than 2 feet below the ceiling to maximize strength. This arrangement will also offer ample storage room.

Step 2 - Construct the Supports

Now you will make the supports for your garage ceiling shelf. You will construct these from 2-by-4 inch lumber. Cut the sides to the length you need, which will be the distance below the ceiling that your shelf will hang. Cut six pieces of this length.

Next cut three more pieces as wide as your shelf will be. Take two of the side pieces and one of the bottom pieces. Attach a side piece to each end of the bottom piece and screw the pieces together. For extra strength, screw a corner brace on the outside of each corner. When you’ve finished, there should be no wobble in the joins. Repeat the procedure to make two more supports.

Step 3 - Attach the Shelf to the Ceiling

If your garage roof is exposed, you’ll be able to see the beams that run across at the top of the walls. However, if your garage has a ceiling, you’ll need to use a stud finder in order to find the studs to which you’ll attach the supports.

At each stud, measure in from the wall to the distance you want the garage ceiling shelf. At this point, screw in one side of a 5-inch corner brace. Now, measure the distance between the outside of the side arms on the shelf supports. Mark this distance on the garage ceiling and screw in another 5-inch corner brace onto the stud.

Take your garage ceiling shelf support and hold it against the ceiling so the corner braces on the studs are tight with the side supports. Screw the side supports to the corner braces and test to ensure it’s secure. Repeat this procedure for the other two supports.

Step 4 - Cut the Garage Ceiling Shelf

Cut your plywood to the desired length. Make sure the overhang from each support is not excessive. The width of the garage ceiling shelf should be the same as the bottom on the shelf support. Slide the shelf into place on the supports. For extra stability, screw it into the base of the supports.
