FOUNDATION INSPECTION REQUIREMENTS for MANUFACTURED HOMES
Manufactured Homes
The homes are usually single wide units or double wide units. Financing of these homes are typically through "FHA". The foundations for these types of homes are required for FHA" financing to meet the "Permanent Foundations Guide for Manufactured Housing", HUD-7584

Foundation Types
Manufactured homes are typically supported with a crawl space foundation or a full basement. Based on our experience, most of the units we inspect are supported with a crawl space foundation. The floor of a crawl space should be covered with either concrete or granular material, such as sand or gravel over a vapor barrier, like a polyethylene sheet. Crawl spaces that experience excessive dampness may cause the frame of the unit to rust prematurely of soften the soil under the footings, which may cause settlement.

Supporting and Anchoring the Home
These homes are required to have a permanent continuous perimeter foundation enclosure, such as a concrete block or cast-in-place concrete perimeter walls to keep out vermin. These perimeter walls are to be attached to the exterior frame of the unit. for stability The perimeter walls cannot be freestanding. The perimeter walls have to be supported on footings that meet the frost depth requirement of the area, (30" deep in the Greater Cincinnati, Ohio region). The main frame(s) of the home are typically supported on center columns or piers, typically concrete block. The concrete block piers are to be supported on concrete footings and the concrete block units must be solid or reinforced, such as with a fiberglass reinforced stucco coating and not loose laid. The homes are typically anchored to the ground with metal strap anchors. There are specific minimum spacing requirements for these anchors that are dependent on the wind load rating of the area, the width of the unit, the spacing of the center beam, whether the house is one or two units wide and the height of the center piers. The anchors have to be anchored through the concrete footings or concrete slab and are not allowed to be anchored into the ground only.

Actual Engineering Inspection
We must have access to the interior of the crawl space when the home has a crawl space. The crawl space has to be reasonably dry for us to access. We cannot access crawl spaces that are blocked with storage, insufficient height under the frame, wet or muddy soil or have an apparent dangerous condition, such as a high content of mold.
For futher information on the "FHA" requirements, please refer to the "FHA Audit Report #2007-KC-0004", dated September 24, 2007.
