How to Inspect Double-Wides, Mobile Homes, Trailers or Manufactured Housing for Defects: detailed procedures, defect lists, references to standards. Here we explain where to look for costly or dangerous problems on mobile homes, trailers, or double-wides. We address all of the major parts and systems of mobile home structures and suggest field inspection procedures as well as common hidden problem and common repair procedures.

Vermilye of New Paltz NY (photo at the top of htis page) passed away on 19 June 2001, so of course you will have difficulty contacting him by normal means. Steve was a leader in our profession, recognized nationally as well as among New York State professional home inspectors for his competence, kindness, honesty, humility, humor, and for his unequivocal commitment to the welfare of his clients. Steve led our interest in mobile home inspections by offering us an opportunity to join with him to work pro-bono in behalf of agricultural workers in the Hudson Valley -- a service which we continue in his memory. We found so many unsafe and un-healthy conditions in the trailers and mobile homes occupied by migrant farm workers that there was almost no safe habitable housing at the facility. The facility owner, responding to suggestions from our report and from the N.Y. Office of the Attorney General and an attorney representing farm workers made extensive improvements in farm worker housing as a result of Steve's initiative. Many of the photographs used to illustrate defects and needed repairs at these mobile homes, trailers, and double-wides came from Steve or from our own photos when we worked together. We all miss Steve Vermilye and his passing remains a great loss. If the information in this report assists anyone in assuring that their home is more safe and secure than it would have been otherwise, that benefit is thanks to Steven Vermilye -- this information is one of his many gifts to the people for whom he cared deeply -- Daniel Friedman.

Definitions: What is a Mobile Home, Trailer, Doublewide, Modular Home, Factory-Built Home, Panelized-Construction-Built Home?The following is the opinion of the author and has not had a technical review by other industry experts. Various trailer, mobile home, and modular housing manufacturers may disagree with some of these views. Corrections and content suggestions are welcome. Characteristics of Trailers as Living SpaceTrailer traditionally describes a usually small, wheeled, home with a history and image of flimsy construction such as wooden 1x3 wall framing clad with aluminum siding, virtually no insulation, and low quality leaky windows. "Trailers" up until the 1970's (my estimate) included both campers which really were intended to be towed by a car or truck and moved often from site to site (though some were left parked for decades at campgrounds), and also lightweight factory-made homes which were intended to be towed once to a home site and then kept there. Our photo (left) shows a trailer that was finally abandoned as a living space. The little blue structure used as an addition to the left of the small house in the photo at the top of this page was undoubtedly a small camper. No one building "trailers" calls them that any longer because of the "flimsy" image. The closest thing to a "trailer" in current products on the market are motor homes and campers. The least-costly campers (such as our pickup truck "slide-on camper") built after 2000 are probably considerably better constructed than the "trailers" of old. In current language (2009), a "trailer" is either a "mobile home" that is more than 20 years old (see below), or it is a camper designed to be moved easily and often from site to site. (Or in different usage, a "utility trailer" is a utility vehicle intended to haul goods or large items and designed to be fastened to the back of a car or truck, and a "tractor trailer" is of course a larger (typically 40 ft long) hauling system for moving goods by highway from city to city.) Trailers may have had their wheels left on, but normally they'd be set on a masonry pier foundation and a skirt installed around to hide the under-trailer area. Characteristics of Mobile Homes as Living SpaceIn the past few decades (to 2006), "trailer" manufacturers have considerably improved the quality of construction of such homes. The national manufacturing and building code standards for these structures have also been improved. Perhaps in part to escape the less than wholesome image of "trailer", manufacturers use the term "mobile home" to describe what is usually larger and better made home than "trailers" of old, though perhaps with similar materials. Mobile homes are built in a factory and are designed to be moved (once and uncommonly, perhaps once again) on its own wheels attached to its own frame to a site where a foundation is prepared and connections to utilities are made. In the U.S., states have regulations about the siting, foundation, steps and entry, wiring, plumbing, tie-downs for wind and storm safety that apply to these homes. Some examples of mobile home regulations for New York State are this website. Individual state regulations will vary - you'll want to see what your state requires. Even within states regulations vary as wind and weather conditions do also. Examples of mobile home improvements include stronger overall wall and roof construction, less leaky roof covering, and windows that are less notoriously leaky. In addition newer mobile homes have, for fire safety, bedroom windows that can be pushed out to a wide opening for emergency exit in case of fire - an important safety improvement. Usually building departments grandfather in older structures, but sometimes they will insist that certain life-safety improvements be made, for example if an older mobile home is being brought to a new site in a new community. If this is the case one or two windows may need to be replaced to provide this important safety improvement. When there is a severe storm or hurricane, mobile home communities are among the worst damaged as a strong wind can completely turn over or demolish mobile homes. For this reason, mobile homes set up in high wind-risk zones have extra requirements for tie-downs to secure the building against upset during a storm. Mobile homes may arrive on wheels but they will be jacked enough to be set on some type of approved building foundation, such as masonry piers or a masonry foundation. In case these terms are not confusing enough, some mobile home makers like to call these "factory built homes". But that use of "factory-built homes" is confusing too since modular homes are also "factory built" but are quite different from trailers or mobile homes. Characteristics of a "Doublewide" Mobile Home or TrailerSome manufacturers provide mobile homes constructed to be joined together, side by side to form a double-width living unit. While a double-wide mobile home is basically constructed by the same materials and methods just described above, the tie-down and connection requirements for these living units may be different in some jurisdictions, since their risk of being blown away in high winds is different. Other installation and support requirements, such as connection of the two units and placement of foundation support will also have to accommodate this variation. Characteristics of Modular Homes or Modular Housing
A modular home is constructed in a factory of one or more sections which are carried to the building site on a trailer and lifted by a crane to be set upon a foundation which has been prepared ahead of time. Modular homes can be quite large, involving four or quite a few more individual sections which are lifted and "set" into place at the site. Some manufacturers provide custom architectural services and can deliver unique, but factory-built homes in sections. Contemporary modular construction of homes have these attributes:

Question: what types of windows are found on mobile homes?I have a question not a comment. Hope you can get back to me on this. We are buying a 1974 mobile home. What kind of windows are in that type of home. Are they roll outs or pull up windows? - Linda Reply:You can see some common mobile home window types in this article: Watch out: At least on older homes these windows are often leaky and may have caused hidden wall and floor damage. Check under the carpet or in the crawl area of your home, especially in floor areas below windows or doors. Question: Who is responsible for the mailbox serving my mobile home ?problem who is responsible for mail boxes the property owner o the resident ? ranaheim@roadrunner.com Reply:Ranaheim Question: How can I track down what's causing high moisture in a doublewide manufactured home?I have a double wide manufactured home that I'm renovated. It has vinyl siding and perforated soffits common on manufactured homes. We've noticed moisture high in the walls all around the home and can't identify the cause. Any ideas? Thank you, - T.B. - Colorado Reply:A competent onsite inspection by an expert usually finds additional clues that help accurately diagnose a problem with too much moisture in a home. That said, gee, with absolutely no information whatsoever about the home you mention, I'd be just arm-waving to offer a specific diagnosis. But I can suggest some directions of investigation for tracking down a moisture problem: Generally the approach is to find the water sources and water or moisture traps. That is, high indoor moisture, enough to put condensation on walls, might be tracked down to one or both of:
If I'm right that you're in Colorado, you're not in such a high humidity area as the Southeastern U.S. That in turn makes me wonder if there is not either water below the home or leaks in or into it from roof, windows or doors (notorious leakers on older manufactured homes). If the moisture is uniform around all of the interior of the home I suspect it could be coming from a source that would equally wet the whole structure - below the entire structure up through floors, or leaks across a wide area of roof. Observing moisture high on walls may just indicate where the cool walls are in contact with warmer, high-moisture-content air inside the home. (Warm moist air rises). If your renovation permits, you might need to make some test cuts to be sure you know where water is and is not, and to be sure you're not renovating by putting a new skin over a rotting or inset infested structure. Sorry I can't be smarter but that's about as much arm-waving as I can dare with no more information. If you'd like to send some photos or further description of what's there and what you're seeing, that may permit some further suggestions. At WATER ENTRY in BUILDINGS we collect a series of building moisture or water entry diagnosis & cure articles that might be helpful. Follow-Up: wet walls traced to frost or ice in the home eaves and attic
The soffits are vented continuously. Snow actually drifts inside the soffit then, when the weather warms, melts and some water runs down the walls. As this can happen many days after the initial precipitation it’s often mistaken for a condensation issue. The installer didn’t have any suggestions for a solution. In fact, he said if I came up with anything to let him know. Any ideas? Reply:We have seen several points of frost or even ice accumlulation at house eaves ane even deeper into the attic in uninsulated HVAC ductwork. Clues that point to the attic ice or frost accumulation as the source of indoor leaks and moistureI think a diagnostic clue that can help track down apparent building leaks or moisture on walls that originates in the attic may be the observation of leaks in a warming weather trend after a long cold spell. Also the moisture shows up only on the exterior walls, not on building interior walls. It doesn't have to be snow blowing into the soffits - which is unusual; anything that allows moisture condense, collect, and freeze in the attic or in attic HVAC ducts can produce such leaks when things thaw out. The cause your installer cited, snow drifts in the soffits, is possible but more common are some of these other problems that can produce the same symptoms:
How do we fix these problems of ice and frost formation in the attic ... it depends. First let's accurately diagnose the cause by a careful inspection in the attic. Wind-wash will be obvious - insulation will have been disturbed. Ice dam leaks leave characteristic stains that we illustrate in that article.
Details about these attic frost, ice, or moisture problems that show up as "leaks or moisture on building walls" and how they are fixed are in the articles cited above. At Inspect Attics for Moisture or Mold we discuss inspecting (and correcting) building attics for evidence of condensation, moisture, or even ice.
