Paper 4 - Hong Kong Building Legislation and Professional Practice

Paper 4 tests the statutory and professional framework that surrounds architectural decisions in Hong Kong: what must be approved, by whom, in what sequence, and what the architect personally certifies. Marks go to candidates who can walk a project through the Buildings Ordinance (Cap. 123) and keep an AP's statutory duties separate from a contractor's site duties.

The statutory roles

  • The Building Authority is the Director of Buildings; the Buildings Department administers Cap. 123 and its subsidiary regulations (Planning, Construction, Administration).
  • An Authorized Person (AP) is the registered professional accountable for the design, submission and supervision of building works.
  • A Registered Structural Engineer (RSE) is separately appointed for structural design and certification; a Registered General Building Contractor (RGBC) or Registered Specialist Contractor (RSC) must carry out the works.
  • These are personal statutory appointments: certification cannot be delegated to unregistered staff.

Approval, consent, occupation

  • Plans are submitted for approval under s.14; the Building Authority's decision is due within 60 days.
  • Approval does not permit work to start - a separate consent to commence works is required, and the AP must give notices at prescribed stages before elements are covered up.
  • On completion, an occupation permit (s.21), or a temporary occupation permit for partial completion, is applied for; Fire Services Department and Water Supplies Department clearances are prerequisites.
  • Change of use and A&A works follow the same approval logic, but planning permission under the Town Planning Ordinance is a separate regime.

Minor works and conduct

  • The Minor Works Control System allows designated minor works by notification instead of full plan approval, in three classes with escalating plan and supervision requirements; a prescribed registered contractor is always needed and BD audits completed work.
  • Under the Architects Registration Ordinance (Cap. 408) only registered persons may call themselves architects. The HKIA Code of Professional Conduct requires competence, honest certification, conflict disclosure and non-misleading advertising.

Worked example

An industrial unit is to become a shop with a new mezzanine. Reasoning: check the OZP first for planning permission; appoint an AP (and an RSE for the mezzanine); submit A&A plans covering means of escape, fire and structure; obtain approval, then consent; let the RGBC build; apply for the occupation permit or a fitness certificate for the new use; obtain FSD clearance for the shop's fire service installations.

Traps

  • Treating plan approval as permission to start on site.
  • Confusing lease conditions (Lands Department) or planning permission with building approval.
  • Assuming minor works involve no professional - the higher classes require prescribed building professional supervision.
  • Blaming the AP for site safety; that duty belongs to the contractor.
