Other approvals

Norfolk County handles the municipal building/plumbing layer. Electrical work is normally a separate ESA notification/inspection stream, and gas/fuels work is regulated through TSSA/authorized fuels contractors. A building permit does not replace those trade approvals. Province/authority source ↗

Good to know in Norfolk County

  • The county also publishes examples of finish work and like-for-like replacements that do not require a building permit.
  • Ontario cities administer building permits under the provincial code framework. A building permit does not automatically resolve zoning or every trade, conservation, heritage or utility approval.
