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

Give the appointed designer the existing plan and a proposed plan with the changes marked. Explain what each affected room will be used for and list any systems being added or altered. The designer can then check the relevant building-authority and DCD requirements.

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?

Size alone does not answer the question. Give the designer a plan showing the proposed changes so they can check whether a fire-safety application is required.

What should I ask my designer?

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