Are concrete blocks or piers considered a permanent foundation?
Permanent foundations consist of many components. Moreover, concrete blocks are considered a permanent foundation when using them in conjunction with seismic E.R.B.S. (Earthquake Resistant Bracing Systems). Additionally, these systemic systems require support piers spaced according to the home manufacturers recommended spacing between the positive earthquake bracing support connections.
Today lenders require foundation certification showing compliance to the HUD-7584 Permanent Foundation Code.
What kinds of homes are supported by piers?
Post and pier homes, manufactured homes, modular homes, and mobile homes are just a few homes supported by piers. Furthermore, piers can be made from stacking concrete blocks. So, often you will find piers considered a permanent foundation.

But, keep in mind not all meet the HUD Permanent Foundation Guide for Manufactured Homes. Read the language carefully and ask specific questions before buying.
