How to Anchor a Garage

Go inside the garage and drill a 1/2-inch hole through the framing studs at each corner with a drill and 1/2-inch bit. Drill the holes 4 inches above the sill plate and through the side of the garage. The sill plate is the board at the bottom where the framing studs attach.

Drill a hole in the same position on a wall stud near the center of the garage door wall. Repeat for the opposite wall of the garage. Ask a helper to place flat washers over 8-inch eye bolts and push the eye bolts through the holes from outside the garage. Slip flat washers over the eye bolt threads and thread nuts over each until they are hand tight. Tighten the nuts completely with a socket wrench.

Measure 6 inches away from the outside garage wall next to the eye bolts. Twist 6-foot auger anchors into the ground with the loop end of the auger pointing away from the garage at an angle. Insert a hammer through the loop end of the auger anchor and use the hammer as a handle to turn the auger anchor.

Continue twisting the anchor clockwise until the plate below the loop is at ground level. Insert the end of a 12-inch long steel cable through the anchor loop and the eye bolt loop. Join the two ends of the cable and secure them together with a cable clamp. Tighten the nuts on the cable clamp with a socket wrench. A cable clamp is a two-piece clamp that tightens over the cable ends. Repeat for all anchors and eye bolts.
