Tips

  • This permit is required in addition to, not instead of, the underlying Residential or Commercial Building Permit when a project falls within the flood plain.
  • Substantial improvement provisions apply automatically if the cost of proposed construction equals or exceeds 50% of the structure's estimated market value — this can trigger full current-code compliance for what would otherwise be a minor remodel.
