How to Look

at a House

A blog with answers
to your questions about

Marriage Line - The joint along which the sections of a double or triple-wide connect.

Skirting - The ventilated enclosure panels for the crawl space under a mobile home.

HUD-Code - All mobile homes manufactured after July 1, 1976, meet a nationwide building code administered by the U.S. Department of Housing and Urban Development (HUD), and are referred to as “HUD-Code” homes in the industry. Homes manufactured before July of 1976, were only required to meet regional standards. Also, earlier homes will not have a HUD data plate sticker inside the home or a HUD tag attached to each section.

HUD Data Plate - A sticker that HUD requires to be posted inside a mobile home that contains key information about the home, such as the name of the manufacturer, date of manufacturer, serial number, and HUD-tag number, along with the wind zone and roof load zone standard it was manufactured to meet.

HUD Tag - Sometimes called the “red tag,” because it is bright red when first installed, the metal tag has a stamped identification number registered with HUD.  It is officially called a “Certification Label.”

HUD-Code Stairs - A stair and landing assembly manufactured to meet HUD-Code requirements and usually delivered all in one piece, including railing and handgrip, to be installed in front of exit doors from a mobile home.

Pit Set - A mobile home that is installed over a shallow pit so that the floor level is closer to the ground around it, but there is still a crawl space under the home, making it look more like a site-built home.

D-Sticker Home - A special category of mobile home that has been reinforced to meet the wind resistance requirements of ASCE 7-88, Exposure D, and allowed to be installed within 1500 feet of the coastline in hurricane wind prone areas.

Manufactured Home - When the HUD-Code was enacted by Congress in the 1970s, the federal law also stipulated that what was formerly called a “mobile home” could only be referred to as a “manufactured home” from that day forward. The industry was trying to move away from its former shoddy reputation, and the new name for the product was one way of improving their image. Most people outside of the manufactured home industry still refer to them as mobile homes, in spite of the legal name change.
