In Perth, Western Australia, electrical and plumbing inspections are governed by a mix of municipal requirements and state building and safety regulators. Owners, builders and licensed trades must follow City of Perth permit requirements and state technical and safety rules for electrical and plumbing work. This guide summarises who enforces inspections, how to apply for approvals, common compliance issues, and the practical steps to resolve notices or appeals in Perth.

Scope & Who Regulates

Local building approvals and plumbing connections are administered by the City of Perth for works inside its boundary; electrical safety, licensing and technical standards are regulated at state level by the Department of Mines, Industry Regulation and Safety (DMIRS). For the local permit process, refer to the City of Perth building pages City of Perth - Building & Approvals[2]. For electrical safety, licensing and inspection obligations see DMIRS guidance DMIRS - Electrical safety[1]. State statutory instruments such as the Building Act 2011 and associated regulations set the legal framework for building work in Western Australia Western Australian legislation[3].

Always confirm whether your project needs a City of Perth permit before work starts.

Typical Inspection Triggers

  • Certificate of compliance requests or final inspection before occupancy.
  • Permit conditions requiring staged inspections (footings, frame, services, final).
  • Complaints about unsafe installations or water/electrical hazards reported to council or DMIRS.

Penalties & Enforcement

Enforcement is shared: the City of Perth enforces local permit and plumbing connection requirements; DMIRS enforces electrical licensing, safety and technical compliance. Specific monetary fines, fee amounts and daily penalties are not uniformly set on the cited municipal and regulator pages and therefore are not specified on the cited page.[2][1]

  • Fines: not specified on the cited page for municipal or DMIRS procedural pages; check the Building Act, local bylaw or DMIRS enforcement notices for exact figures.[3]
  • Escalation: first, repeat and continuing offences may attract increased penalties or continuing offence fees, but ranges are not specified on the cited regulator or council summary pages.
  • Non-monetary sanctions: common enforcement actions include stop-work or prohibition notices, rectification or compliance orders, suspension of licence or prosecution in court where safety breaches occur.
  • Enforcer and complaint pathway: for electrical safety contact DMIRS enforcement; for permits, plumbing connections and building inspections contact the City of Perth planning and building services.[1][2]
  • Appeals and review: specific appeal routes and time limits are governed by the Building Act 2011 and related regulations; time limits are not specified on the cited overview pages and must be confirmed in the Act or by contacting the administering office.[3]
  • Defences/discretion: decision-makers may consider permits, retrospective approvals or evidence of reasonable excuse where available, but specific statutory defences depend on the instrument cited in the enforcement notice.
If you receive a notice, start with the named contact on the notice and gather inspection reports and permits before responding.
