FHA Foundation Requirements of NC, including Charlotte and
On VA and FHA-insured loans, the foundation
on all mobile and manufactured homes must meet an acceptable
standard of structural stability and immobility as
determined by a structural or professional engineer
(PE). The engineering inspection or FHA
certification must be conducted by a licensed
professional engineer in North Carolina, typically a structural engineer
who practices in the Charlotte and surrounding areas,
and a letter of approval must be supplied to the lender.
The FHA foundation certification letter must bear the
seal of the professional engineer and be signed and
The HUD foundation engineering inspection ensures that the
mobile or manufactured home foundation is structurally adequate based
upon the provisions of the HUD Handbook (The Permanent
Foundation Guide for Manufactured Homes, 1996). At
