Before you apply

  • Call the City of Lenexa Community Development: (913) 477-7600
  • Search the municipal code for the chapter that covers your zoning district and proposed use.
  • Use the local zoning map to look up your parcel's zoning designation before applying for a permit.
  • 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 Lenexa and frequently restrict ADUs, fences, and exterior changes beyond what zoning allows.
