Check with the zoning department for your county. A lot of areas in Arizona have restrictions against mobile homes (which were built before June 15, 1976) and homes built to HUD code. So one of the Cavco plants in Phoenix gets around that restriction by building homes to UBC code, using the same materials, same floor plan, built on a steel undercarriage, towed to the site, same paper work as a home built to HUD code. Is installed and looks exactly like a home constructed to HUD code but because it was built to UBC code is acceptable to the zoning authorities that object to HUD code!! But then if your county has restrictions against factory built homes, everything including trailers, mobile homes, manufactured homes, panel homes, kit homes, industrialized homes, modular homes, etc are out of luck. I wonder if they will figure out that by using the terms of factory built--that means a site built home couldn't have pre-engineered trusses, factory assembled cabinets, etc, etc if the letter of the restriction was applied??
By the way, you might be surprised, those nice two story log homes you have seen might have been factory built! There are some factory built homes, whether it was built to HUD or UBC cannot be identified as being factory built until you get verification of the building code from the manufacturer. One of the local manufacturer dealer and all his relatives live in homes constructed to HUD code that have 3,000 to 4,000 square feet, more bells and whistles than a site built home at half the price. You can only tell they are HUD code homes because of the name of the owner--and he doesn't sell modulars. Redman Homes under the name of Genesis Homes is building UBC homes of Santa Fe/Pueblo style homes that the only identification will be a crawl space since site built homes in Arizona are built on concrete slabs. In the future they will probably come up with a way of doing that too. After all 4,000 square foot homes on concrete pads are being picked up out of the way of the freeway and moved hundres of miles. Saw an episode on Home Time several weeks ago where they picked up a home on a concrete slab, raised it 9' in the air then built two two garages and storage room the same size underneath it. Amazing to watch.
