1. Manufactured or mobile housing shall be considered as permanent-site or modular housing only when it meets the following (federal) certification criteria:
a. The manufacturer must certify that the structure is designed only for erection or installation on a site-built permanent foundation. A
SITE-BUILT PERMANENT FOUNDATION is a system of supports, including piers, either partially or entirely below grade, which is:
(1) Capable of transferring all loads imposed upon the structure into soil or bedrock without failure;
(2) Placed at an adequate depth below grade to prevent frost damage; and
(3) Constructed of concrete, steel, treated lumber or grouted masonry.
b. The manufacturer must certify that the structure is not designed to be moved once erected or installed on a site-built permanent foundation.
c. The manufacturer must certify that the structure is designed and manufactured to comply with the city’s adopted Building Code, or equivalent.
d. The manufacturer must certify that, to the manufacturer’s knowledge this structure is not intended to be used other than on a site-built permanent foundation.
2. Such certification shall be proof of the housing unit’s status as a “modular” unit; without such certification, any manufactured housing unit shall be considered a “mobile home” and treated as such for purposes of regulation.
