Before you apply

  • Call the City of New Castle Planning and Zoning Department: (724) 656-3540
  • Search the municipal code for the chapter that covers your zoning district and proposed use.
  • Check FEMA flood zone for your parcel — flood-zone status changes setbacks, foundation requirements, and insurance.
  • Check your HOA CC&Rs and recorded deed restrictions — they are common in New Castle and frequently restrict ADUs, fences, and exterior changes beyond what zoning allows.
