A bracket forms one or more U-channel for receiving a beam that supports a portion of a building. An adjustable structure for supporting a beam includes the bracket and a concrete footer or pier having an anchor bolt, wherein the anchor bolt has one end securely embedded within the concrete and threaded end extending upward from the concrete. A leveling nut is threaded onto the anchor bolt below a base plate of the bracket, a top nut is threaded onto the second end of the anchor bolt above the base plate, and a block is disposed between the concrete footer or pier and the base plate to support the weight of the beam. The adjustable structure enables a person to adjust the elevation of an identified portion of a building that is not level.
