Mobile Home Wind Zone Map Across the USA
Mobile homes, also known as manufactured homes, are a popular housing option due to their affordability and flexibility. However, one crucial factor to consider when placing a mobile home is the wind zone of the area. Wind zones are regions defined by the Department of Housing and Urban Development (HUD) that dictate the structural requirements for mobile homes to withstand high winds. Understanding these zones is vital for ensuring the safety and durability of mobile homes. Here’s a breakdown of wind zones across different geographical regions in the USA.
Wind Zones Overview
The United States is divided into three primary wind zones:
- Wind Zone I: These areas are considered low-risk for high winds. Most of the central United States falls into this category. Homes in this zone must withstand winds up to 70 mph.
- Wind Zone II: These regions have a moderate risk of high winds. They include coastal areas that are not in the direct path of hurricanes but can still experience significant wind speeds. Homes in Wind Zone II must be built to withstand winds up to 100 mph.
- Wind Zone III: These areas are high-risk and include regions that are prone to hurricanes and other severe windstorms. Homes in Wind Zone III must withstand winds up to 110 mph.
Will Mobile Home Movers Near Me Know Wind Zone Restrictions?
This is a great question. Most manufactured home movers will know the wind zone restrictions for the counties that they operate in. However, you must call the county you are moving the double wide mobile home or single wide trailer to and ask about their wind zone rating, thermal rating, and in northern state, snow load rating. We highly recommend you know all the specifications a mobile home should have for your region before purchasing a trailer to move to your location.

Geographical Manufactured Home Wind Zone Breakdown
Northeast (Maine, New York, New Jersey, Pennsylvania, etc.)
- Predominantly Wind Zone I with some coastal areas in Wind Zone II.
- Northeastern states typically experience lower wind speeds, with exceptions in coastal areas where stronger winds can occur.
Southeast (Florida, Georgia, South Carolina, North Carolina, etc.)
- Mixed Wind Zones, predominantly Zone II and Zone III.
- Florida, in particular, is mostly in Wind Zone III due to its high risk of hurricanes.
- Coastal Carolinas also fall into Wind Zone III, while inland areas are Zone II.
Midwest (Ohio, Illinois, Indiana, Michigan, etc.)
- Primarily Wind Zone I.
- The Midwest is less prone to high winds compared to coastal regions, making it predominantly Wind Zone I.
South (Texas, Louisiana, Mississippi, Alabama, etc.)
- Wind Zones I, II, and III.
- Coastal regions of Texas, Louisiana, and Mississippi are in Wind Zone III, while inland areas fall into Zone II and Zone I.
- Alabama is a mix, with northern areas in Wind Zone I and southern coastal regions in Zone III.
West (California, Nevada, Oregon, Washington, etc.)
- Primarily Wind Zone I with some coastal areas in Wind Zone II.
- Western states generally experience less severe wind conditions, with higher risks in coastal areas.
Mountain States (Colorado, Utah, Montana, Wyoming, etc.)
- Mostly Wind Zone I.
- These areas are generally not prone to high wind events, categorizing them into Wind Zone I.
Southwest (Arizona, New Mexico, Oklahoma, etc.)
- Predominantly Wind Zone I with some areas in Wind Zone II.
- Oklahoma, known for its tornado activity, still falls primarily in Wind Zone I due to the specific nature of tornado risks compared to sustained high winds.
Pacific Northwest (Washington, Oregon, Idaho)
- Wind Zone I with coastal areas in Zone II.
- The coastal regions can experience strong winds, especially during storm seasons.
Conclusion
When considering the placement of a mobile home, it’s essential to know the wind zone of your area. This ensures that your home is built to withstand the wind conditions specific to that region, providing safety and durability. For detailed information, you can refer to the HUD Wind Zone Map.
By understanding the wind zones across different geographical regions, mobile home owners and buyers can make informed decisions and take the necessary precautions to protect their investments and ensure their homes are safe.
FAQ:
What is a wind zone 1 mobile home?
A wind zone 1 mobile home is designed to withstand wind speeds up to 70 mph. This zone covers the central parts of the United States, where hurricanes and other high wind events are less common. HUD regulations ensure that manufactured homes in this zone meet specific safety standards. When considering purchasing a wind zone 1 mobile home, you must understand the wind speed limits and heat requirements for your area, especially if you’re in regions like Louisiana or Florida where conditions can vary.
How can I find a mobile home wind zone map for my county?
A mobile home wind zone map is essential for determining the wind resistance requirements of manufactured homes in different regions. You can find out what wind zone your county is by calling the permitting office for your county. These maps indicate areas with varying wind speeds and risks, including zones prone to hurricanes and tornadoes. For example, states like Florida, South Carolina, and Alabama have specific wind zones that impact home construction standards. Thermal zones and wind-borne debris considerations are also included in these maps, which follow ASCE 7 guidelines.
What are the requirements for a wind zone 2 mobile home?
A wind zone 2 mobile home must be built to withstand wind speeds up to 100 mph. This zone covers areas that have a moderate risk of hurricanes and tornadoes, such as parts of South Carolina and Louisiana. These homes must adhere to strict HUD guidelines and wind zone and thermal zone maps to ensure they can handle the increased wind speeds and heat. If you’re considering a double wide mobile home in this zone, ensure it meets the necessary standards for durability and safety.
Are wind zone 3 mobile homes for sale more expensive?
Wind zone 3 mobile homes, which must withstand wind speeds up to 110 mph, can be more expensive due to their reinforced construction. These homes are designed to endure severe weather conditions, including hurricanes. Areas like Charleston, SC, fall into this category. When looking for a single or double wide mobile home, prefab homes, or specific sq ft options, consider that the enhanced wind load requirements can affect the overall cost. FEMA guidelines also play a significant role in the design and pricing of these homes.
