Part of our home inspection is identical to evaluating a site-built home; such as checking the electric panel and wiring, a/c system, plumbing piping, roof, switches and faucets, and so forth. But we also look at some additional items:
We check for missing or loose trim, skirting (with proper ventilation) or siding panels.
We evaluate any site-built additions. Since a mobile home is designed only to support its own weight, any additions should be freestanding and not bearing on the walls of the mobile home, and should be property flashed at areas of contact.
The frame of a mobile home is interconnected large I-beams. We verify that they are not bent or heavily rusted.
We check the foundation piers, to confirm that they are not damaged or leaning, they are in bearing contact with the mobile home frame, that the holes in the pier blocks are facing upward, and the pier caps are not rotted or cracked, and any leveling shims are secure.
Examine the vapor barrier under floor framing for tears, deterioration, sagging.
Confirm that there is perimeter blocking under any large wall openings, such as a sliding glass door.
Determine the type and spacing of the anchor straps, and how they are attached to the frame, to confirm that they meet the standards in place at the time the home was installed.
Look for any loose or corroded anchors or straps.
