Survey Submission Requirements

Beginning January 1, 2021, the following policy and guidance for the submission of foundation surveys, as-built surveys, under construction flood elevation certificates, and finished construction flood elevation certificates will be used.

All Foundation surveys and as-built surveys shall have the required setbacks and buffers delineated and labeled on them.

New Single Family Residential Projects

  1. The Foundation survey will be required to be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at first lift, if multiple lifts) for elevated block foundations.
  2. The As-built survey will be required to be submitted prior to the:
    • Certificate of Occupancy Inspection, or the Final Inspection; or
    • Prior to the Final inspection of elevated generator platform
  3. The Under Construction Flood Elevation Certificate will be required to be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at last lift, top of block, if multiple lifts) for elevated block foundations; or
    • Top of piers/piles for pier/pile foundations. (V Zone)
  4. The Finished Construction Flood Elevation Certificate will be required to be submitted prior to the:
    • Certificate of Occupancy Inspection, or the Final Inspection

Note: If the project is not located in a flood zone then an elevation certificate is not required.

Single Family Residential Addition Projects

The Foundation survey will be required if the proposed addition is located within 20% of the required adjacent setback/buffer distance. (Example: If the adjacent setback/buffer distance is 5 feet and the addition is to be built within 1 foot from the setback/buffer, then a Foundation survey is required).

  1. The required Foundation Survey will be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at first lift, if multiple lifts) for elevated block foundations.
  2. The As-built survey will be required to be submitted prior to the:
    • Certificate of Occupancy Inspection, or the Final Inspection; or
    • Prior to the Final inspection of elevated generator platform
    Note: If the addition is enclosing an area within the existing footprint of the structure and is not located within 20% of the setback/buffer, then the existing As-built survey of the structure may be used for both the Foundation survey and As-built survey requirements for the addition.
  3. The Under Construction Flood Elevation Certificate will be required to be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at last lift, top of block, if multiple lifts) for elevated block foundations; or
    • Top of piers/piles for pier/pile foundations. (V Zone)
  4. The Finished Construction Flood Elevation Certificate will be required to be submitted prior to the:
    • Final Inspection.
  5. For new equipment (ex, generators), A Statement of Elevation from a SC licensed Surveyor is required for the equipment servicing the structure prior to the:
    • Final Inspection
    Note: If the addition is to be located at the same elevation as the existing structure, then the existing Finished Construction Flood Elevation Certificate may be used as the Under Construction Flood Elevation Certificate and a new Finished Construction Flood Elevation Certificate will be required prior to theFinal Inspection.

New Commercial Projects

  1. The Foundation survey will be required to be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at First Lift, if multiple lifts) for elevated block foundations.
  2. The As-built survey will be required to be submitted prior to the:
    • Certificate of Compliance Inspection;
  3. The Under Construction Flood Elevation Certificate will be required to be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at last lift, top of block,if multiple lifts) for elevated block foundations; or
    • Top of piers/piles for pier/pile foundations. (V Zone)
  4. The Finished Construction Flood Elevation Certificate will be required to be submitted prior to the;
    • Certificate of Occupancy Inspection, or the Final Inspection.

Commercial Addition Projects

The Foundation survey will be required if the proposed addition is located within 10% of the required adjacent setback/buffer distance. (Example: A Foundation survey is required if the addition is to be built within 2 feet measured from the setback/buffer and the set back/buffer is 20 feet).

  1. The required Foundation Survey will be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at first lift, if multiple lifts) for elevated block foundations.
  2. The As-built survey will be required to be submitted prior to the:
    • Certificate of Compliance Inspection, or the Final Inspection. Note: If the addition is enclosing an area within the existing footprint of the structure and is not located within 10% of the setback/buffer, then the existing As-built survey of the structure may be used for the Foundation survey. A new As-built Survey will be required prior to the Certificate of Compliance and or Final Inspection.
  3. The Under Construction Flood Elevation Certificate will be required to be submitted prior to the:
    • Slab inspection for slab on grade foundations; or
    • Block Inspection (at last lift, top of block, if multiple lifts) for elevated block foundations; or
    • Top of piers/piles for pier/pile foundations. (V Zone)
  4. The Finished Construction Flood Elevation Certificate will be required to be submitted prior to the:
    • Final Inspection.
  5. For new equipment (ex, generators), A Statement of Elevation from a SC licensed Surveyor is required for the equipment servicing the structure prior to the:
    • Final Inspection
    Note: If the addition is to be located at the same elevation as the existing structure, then the existing Finished Construction Flood Elevation Certificate may be used as the Under Construction Flood Elevation Certificate. A new Finished Construction Flood Elevation Certificate will be required prior to the Final Inspection.
