Legs are anchored to a mobile building and preferably also to the ground, concrete, or other supporting surface, so that the building cannot be blown or shaken off of the legs, the legs preferably cannot slide/skid along the ground, and the legs preferably cannot twist or collapse. Each leg may be hinged and/or clamped to a girder of the building. A leg upper portion is an open, generally triangular, box-like case, which resists deformation, tilting, and twisting, and which includes an abutment plate for abutting against and supporting the girder. A leg stem is slidable in the upper portion, wherein upper and lower locking members such as threaded nuts lock the leg stem in place relative to the upper portion to make the leg a single, rigid unit. A foot, having a multiple-direction pivot connection, may be fixed to the ground or to a block or other supporting surface. In a preferred embodiment, a u-joint is provided between the leg and the foot of the system, and a generally horizontal clamp attaches the foot to a footing block provided on or in the ground. Multiple legs may be pivotally attached to, and folded up against, the underside of a mobile home during transport. When the home is ready to be installed at its permanent site, the legs may then be folded down to their support position, adjusted to level the home at a desired elevation, anchored to the ground or concrete block, and cross-braced by tightened diagonal cables. Optionally, a rigid bar may be installed between the feet of each pair of legs to further limit or prevent the legs of a pair from pivoting out away from each other.
