Tips

  • Commercial Remodels use the same tiered valuation-based fee table as residential remodels — not the occupancy-per-square-foot table used for new construction.
  • A Change of Occupancy triggers additional documentation (Change of Occupancy Permit Requirements) and likely accessibility upgrade review.
  • Submit one permit per commercial tenant space or unit — multi-tenant buildings need a separate permit for each space undergoing work.
