Substantial Improvement/Damage Notice to Property Owners

Restoring your home after a storm? Additions, renovations, or remodeling your home? Here’s what YOU need to know about the 50% Rule. Save yourself time, aggravation and money. Please read the following information:

If a building is “substantially damaged” or “substantially improved”, it must be brought into compliance with the latest federal, state and local floodplain regulations, including elevating the building to or above the 100-year flood elevation.

Substantial Damage means damage of any origin sustained by a structure whereby the cost of restoring the structure to it’s before damage condition would equal or exceed 50 percent of the market value or replacement cost of the structure before the damage occurred. (Note: The cost of the repairs must include all costs necessary to fully repair the structure to it’s before damage condition)

Substantial Improvement means any reconstruction, rehabilitation, addition or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the “start of construction” of the improvement.

If a building is “substantially damaged” or “substantially improved”, it must be brought into compliance with the community’s flood damage prevention regulations, including elevating the building to or above the 100-year flood elevation.

Following National Flood Insurance Program requirements, we have the responsibility to determine “substantial damage” and “substantial improvement” and have implemented the following procedures to do so:

  1. Your community will estimate Market Value by using the tax assessment value of your structure (excluding the land), plus about 15% to 20%. If you disagree with this estimate of Market Value, you may hire a state licensed appraiser and submit a comparable property appraisal for the depreciated value of the structure.
  2. You must obtain and submit to your Building Official a detailed and complete cost estimate for the addition, remodeling, reconstruction or for the repair of all damages sustained by your home, prepared and signed by a licensed general contractor. Your contractor must sign an affidavit indicating that the cost estimate submitted includes all damages or all improvements to your home, not just structural. Your community will evaluate the cost of improvements or repairs and determine if they are fair and reasonable. For damage repairs, pre-storm prices and rates will be utilized. The cost of improvements or repairs does not include items not considered a permanent part of the structure. (i.e. plans, surveys, sidewalks, pools, screens, sheds, gazebos, fences, etc.)
  3. If your home is determined to have “substantial damage” or is proposed to be “substantially improved”, then an Elevation Certificate must be submitted to your community to determine the lowest floor elevation. Garages and carports are not considered to be the “lowest floor”.
  4. If the lowest floor is below the 100-year flood elevation, the building must be elevated to or above that level. Likewise, all electrical and mechanical equipment (heating and cooling, etc.), bathrooms and laundry rooms must be elevated to or above the 100-year flood level. Only parking, building access and limited, incidental storage is allowed below the flood level. Non-residential buildings may be “flood-proofed” instead of being elevated. If the lowest floor, electrical and mechanical, equipment, laundry and bathroom are already above the 100-year flood elevation, the building can be repaired and reconstructed if it meets code requirements.
  5. Building plans must be prepared to show how the building is to be elevated. If located in the V-zone, Coastal High Hazard Area, or if the building is to be flood proofed, these plans must be prepared and certified by a registered professional engineer or architect. Certificates for this purpose are available from the Building Official. Any below BFE enclosures in V-zones must have breakaway walls certified by a structural engineer.
  6. Following a Presidential disaster declaration, the Small Business Administration may make loans available for both homes and businesses for purposes of elevating the structure to or above the 100-year flood elevation. Proof of “substantial damage” from your community is required.
