Documents Required For Submittal :

Two (2) Sets of Scaled Plans and a CD in pdf format . One set of paper scaled plans will be stamped and returned to the contractor to be retained at the job site.

  • Site plan
  • Foundation plan

If your building is classified as an Assembly, Educational, Institutional, or Hazardous by the Building Code or the total building area is over five thousand (5,000) square feet, the plans must be prepared and sealed by a licensed architect, structural engineer for structural plans and engineer for Electrical, mechanical and plumbing plans. All design professionals must be licensed to practice in the state of South Carolina.

Fee Calculation:

A construction valuation is determined using the latest version of the ICC Building Valuation data chart which is found on the ICC website www.icccsafe.org . Occupancy class and type of construction will yield a per square foot cost. This cost is multiplied by the square footage in the product and a valuation is assigned. This may be higher or lower than the actual contract cost. The calculated valuation derived from the ICC Building valuation Data table will be used in all cases. Once a valuation is assigned, the valuation is multiplied by a factor on three-fourths of one percent or .0075. The result is the cost of the permit. Plan review fees are calculated at 10% of the permit fee cost and are payable along with the permit fee. Shell buildings will be calculated at at eighty (80) percent of the total building value. Upfit valuation is the remaining twenty (20) per cent of total building valuation. Again, upfit permit contract cost may be higher or lower than calculated building valuation.

How do I calculate the Building Valuation

County Council has mandated the use of the ICC Building Valuation Data table as produced by the International Code Council.  We adopt the February edition to be implemented in April each year.   It provides a per square foot price for each Occupancy class and each Construction type.  We have provided it in both pdf and excel formats for your convenience.  You simply look up your project , find the applicable cost per square foot and multiply it by your building square footage.  This gives you the building valuation.

To calculate your permit, take the valuation and multiply by .0075. This is your permit fee.  Plan review fee is 10% of the permit fee.  Zoning fees are separate.
