Preface
This is the second edition of CSA Standard Z240.10.1, Site Preparation, Foundation, and Anchorage of Mobile Homes. It supersedes the previous edition published in 1986.
The Standard has been upgraded from a Recommended Practice to mandatory practice in response to concern expressed by regulatory authorities, insurance companies, homeowners, and mobile home manufacturers. This Standard is intended to be referenced by the regulatory authority, park owners, and others so that improved onsite installation of mobile homes can be achieved.
Requirements for all the key aspects of this Standard have been updated, and sketches of typical arrangements have been expanded and relocated to the Appendices.
Considerable effort was devoted to the treatment of anchorage requirements resulting in the development of a new formula for resistance to wind-pressure loading and recommendations for mobile homes in tornado-prone areas.
This Standard was prepared by the Subcommittee on Foundation and Anchorage Systems for Mobile Homes and the CSA Technical Committee on Factory Built Houses under the jurisdiction of the Standards Steering Committee on Industrialized Building Construction and was formally approved by these committees.
