Home renovations and Civil Defence: checking the requirements

The word “renovation” does not establish whether a fire-safety approval is needed. Describe the actual changes and check the applicable route.

In this guide

Do not assume that all home renovations are exempt, or that every renovation needs the same Civil Defence application. Have the scope checked against the governing authority’s current requirements.

Describe the changes that need review

Begin with the full scope of the renovation, including changes to the layout, use and installations. The appointed designer can then check the building authority’s application requirements and identify any fire-safety submission needed.

Gather the layout and existing approvals

Collect the existing approval records, the proposed layout and information about installations being changed. Ask the appointed designer to identify the required safety review and any completion documents.

Confirm the fire-safety requirements

  1. Define the work

    Show the full change rather than only the room names.

  2. Check the application

    Confirm the building or alteration route for the property.

  3. Clarify fire-safety requirements

    Identify the required document and responsible applicant.

  4. Keep the answer with the file

    Record the official requirement and any applicable conditions.

Check the building authority’s requirements too

DCD’s engineering guidance and the building authority’s application requirements should be read together. The precise service, rather than a generic statement about villas, is the appropriate basis for the project checklist.

Common questions

Are all villa renovations exempt from DCD?

The requirements depend on the work and the applicable building-authority process. Have the proposed changes reviewed before assuming that a renovation is exempt.

Does being a small job decide it?

The nature of the changes matters as well as their extent. Describe the layout, use and installations being changed so the appointed designer can check the relevant application requirements.

What should I ask my designer?

Ask which fire-safety requirements apply, who confirms them and what documents are needed at each stage.
