RE: Comparative Wind Load - Site Built and Manufactured Homes
Dear Mike:
Manufactured Homes are built to a Federal Construction Standard published and
enforced by the Department of Housing and Urban Development (HUD) .
Under the HUD Standards, Iowa is in Wind Zone 1, which requires a dwelling
unit to be designed to a minimum wind load of 15 PSF Horizontal with an uplift
of 9 PSF. Site built units would have to meet the Uniform Building Code (UBC)
or the One and Two Family Dwelling Code, both are identical for Iowa,
depending on the units exposure ("C" Severe-wide open flat terrain and "B" has
terrain which protects the unit) . General wind loads for Iowa would require
horizontal 25 PSF, uplift 15 PSF unless it is engineered to UBC, 1988
Section 2311.
Hope this answers your questions. Please feel free to contact this office if
you have concerns.
Sincerely, -�
C. E. Peter Green
