Commercial Plan Review

Commercial Plan Review

Plan review for commercial construction includes any of the following for any commercial, multi-family dwellings (3 or more units), and mixed-use building within the City of Charleston:

  • Additions
  • Alterations
  • Demolitions
  • New Construction
  • Renovations

Please be advised all work (including painting, interior finishes, etc.) in a Special Flood Hazard Area requires a permit. Please see the guidelines for commercial review for additional plan review information.


Our goal is to review and approve all submittals within a 20-day time frame. Projects consisting of smaller renovations, additions, fences, pools, etc, may be "walked-through" the Permit Center for same-day permitting if all requirements are met and approvals granted.


Requirements at time of submittal:

  • 3 full sets of architectural, structural, mechanical, electrical, and plumbing/fuel gas plans, if applicable, all signed and sealed by licensed design professionals in South Carolina.
  • 3 Site plans with tree statement
  • Application (PDF)
  • For any revisions, include a completed application (PDF)
  • COMCheck (for new construction, additions and major renovations)
  • Geotechnical report (for new construction and additions)
  • Proof of compliance with SCDHEC regulations (PDF) for asbestos testing
  • V-Zone Breakaway Wall Certificate (PDF) (for new construction and additions if a property is located in a V-Zone)
  • V-Zone Design Certificate (PDF) (for new construction and additions if a property is located in a V-Zone)


Please note that most projects will require review and approval from multiple departments. In most cases, these reviews can be performed concurrently, though separate application processes may be required. Please see scenarios that may trigger reviews from other departments:

  • Projects located within the Old City and Old and Historic Districts that include work affecting the exterior of the building will require review and approval from the Board of Architectural Review (BAR).
  • Projects that include new construction, changes in building footprint, construction of accessory structures (garages, sheds, fences, pools), changes in building height or use (e.g, conversion to short-term rentals), OR the removal of trees will require review and approval from the Zoning Division.
  • Projects that include disturbance to right-of-ways (curb cuts, sidewalks, driveway aprons, seeding, irrigation, etc.) or that may encroach into public or private easements will require review and approval from the Engineering Division.

Please be advised that this list may not account for all potential scenarios.
