Who must have an engineering certificate for their manufactured home foundation?

How do I meet the requirements for a permanent foundation?
Dead loads, snow loads, wind loads and seismic loads must all be taken into account.
There must be a perimeter, frost line protected strip foundation as well as frost line protected piers under the chassis.
The stacked blocks that the unit actually sits on must not only be mortared, they must be attached with rebar to the footing and bolted and/or welded to the chassis frame, unless there is an alternate, site-specific engineered design (which Hayman Engineering, Inc. can provide and can save you hundreds to thousands of dollars).
The design must include protection against horizontal shearing forces and uplifting forces. This can require additional strapping between the stacked blocks.
Finally, it means that this design must be stamped by a licensed professional engineer verifying that HUD requirements have been met.
