Wind Zone IIIĪs the wind zone number goes up, so does the wind speed. Although wind zone II is significantly smaller than wind zone I, it covers most parts of Florida. Homes in wind zone II are built to hold out against wind speeds up to 100 miles per hour.Īs a result, the United States government has designated wind zone II as an area where people are deemed to be at high risk of damage due to hurricanes.Ī wind zone map shows the location of this wind zone II and the probability of your home being in this zone, depending on your proximity to either the Gulf or Atlantic coast. The northeast, the midwest, and the pacific northwest are all in wind zone 1. This area includes most of the U.S.A, except for a few southern states. The majority of the United States is in wind zone 1. In order to avoid destruction, the manufacturer must design homes that can withstand wind speeds up to 70 miles per hour. It’s an area with winds up to 70 miles per hour. Wind zone I is the most lenient area for building homes. Let’s look at the different wind zones that are commonly talked about: Hopefully, by now, you understand the wind zone better. Therefore, any installation must be done in accordance with wind zone ratings. What You Need to Know About Wind ZonesĮarlier, we established that there is a HUD Code for mobile homes, which includes wind zones. The primary purpose of the roof load zone, also known as the snow load zone, is to guarantee that mobile homes are built to bear the weight of snow. The roof’s slope affects how much snow accrues on it during a storm. The roof load zone determines how steep the roof of your home can be. The climate zones differ, determining what needs to be planted and grown where. Since the United States is a large and diverse country, the temperatures experienced in different areas of the U.S. So how are thermal zones determined, you ask? Like a wind zone, a thermal zone is divided into three categories. To make things easier, experts divide the U.S. These winds often bring in storms from Texas, as well as moisture from the Gulf of Mexico.ĭepending on what time of year it is, you might experience different levels of wind. In the Midwest, for example, the prevailing winds are from the southwest. The United States is a diverse place, so it’s no surprise that different regions within the country experience different strengths and wind types. As a result, you must ensure that your home complies with the standard requirements (three wind load zones), or your mobile home’s installation and clearance will be delayed. Some manufacturers, for example, will build homes that can withstand wind zone III ratings, while others may not. Most manufacturers will offer mobile homes based on their target market, and, as a result, the standard of their homes will vary. With that said, the members of the Manufactured Housing Institute include home builders, retailers, community operators, lenders, suppliers, and affiliated state organizations. The Manufactured Housing Institute (MHI) is the only national trade association representing the factory-built housing industry. In the 1990s, HUD updated the Federal Manufactured Home Construction Safety and Durability requirements to reflect new data on hazards, like snow, seismic activity, and wind safety, to ensure that the life expectancy of a mobile home was for the long haul.Īccording to the Manufactured Housing Institute, 22 million Americans live in manufactured homes, therefore wind zones are significant if you’re one of them. You may wonder, what is a wind load? A wind load is the amount of force that a house must withstand to be considered appropriate for a specific zone. One such regulation was the three wind load zones requirement, which homes must withstand. Wind zone was created in 1976 by the Department of Housing and Urban Development (HUD) to ensure that manufactured homes are safe. Let’s discuss what you need to know about mobile home wind zone ratings in detail. So how do you know whether or not your mobile home is in the right wind zone? Most homes that face destruction are normally in wind zones where they are not supposed to be.
