Substantial Improvement Requirements

The National Flood Insurance Program requires an existing building to meet the same construction standards as a new building when making substantial improvements to the building or if the building is substantially damaged. Property owners that make repairs and/or improvements to their residence where the combined total of the improvements or repairs over a 5-year period are 50% or more of the structures value, must also meet the same standards as a newly constructed building.

Signed and sealed elevation certificates and surveys are required for all new and substantially improved buildings before a Certificate of Occupancy can be issued.  Elevation Certificates must be signed and sealed by a land surveyor, engineer or architect that is authorized by law to certify such a document.

Note: Only FEMA Form 086-0-33 (revised 7/2012) elevation certificates can be used.
