Residential open-kitchen fire safety in Hong Kong: checks before renovation

Do not remove the detectors or sprinklers serving a residential open kitchen. Check the approved layout and equipment before renovation; restaurant cooking follows a different regime.

If there is fire or immediate danger

Leave the premises using a safe route and call Hong Kong emergency services on 999. Do not remain to investigate or use a lift.

Legal information

This guide helps with initial planning; it is not legal advice or an engineering assessment of your premises. Confirm the requirements against the use, approved plans, licence conditions, written directions and current official documents.

Quick answers

Can I remove a detector that sounds during cooking?

Do not remove or cover it. First address safety, then ask management and an appropriate contractor to investigate. Evacuate and call 999 if a fire is suspected.

Start with the approved residential design

This guide concerns residential open kitchens. FSD's residential guidance tells owners and occupants not to remove or obstruct installed smoke detectors and sprinkler heads and to arrange proper maintenance.

If you propose removing a wall to create an open kitchen, have appropriate professionals review the approved plans and feasibility first. Existing fire equipment does not establish approval for any proposed alteration.

Review equipment before changing ceilings or cabinets

Tall cabinets, ceilings and decoration can obstruct equipment. Mark fire installations on the renovation plan and ask the contractor about relocation, protection, system coordination and testing after the work.

Report damage, paint contamination or abnormal indications to management and the contractor during work. Do not remove detectors or leave equipment covered as a way to avoid unwanted alarms.

Collect usable equipment records before moving in

Include equipment photos, models, completed work and test results in the handover pack, with a maintenance contact. Tenants should also ask the owner about known defects and previous alterations.

If the premises differ from the approved layout, document the issue and seek a professional review. Obtaining an installation certificate alone does not resolve questions about approval for building alterations.

Practical checklist

  • Check approved residential plans and layout
  • Record detector and sprinkler positions
  • Review cabinets, ceilings and obstructions
  • Confirm shared-system arrangements with management
  • Keep test, alteration and maintenance records

Discuss residential fire-equipment alterations and checks

Share equipment photos and renovation plans, including any wall, ceiling or equipment-position changes, so we can establish the scope.

  • Review installations and alteration impacts
  • Coordinate access and systems with management
  • Follow up applicable installation, tests and records
