HDB renovation permit checks should happen before flat owners confirm hacking, bathroom, window, door, electrical or layout works, because some jobs need approval before contractors start.
The Basic Rule
HDB says renovation contractors submit the electronic permit application with the flat floor plan and proposed works. Owners should not treat the permit as a small admin item after paying a deposit.
Practical Checks
- Use an HDB-registered renovation contractor where required.
- Confirm whether the proposed work needs a permit before works begin.
- Keep the approved scope, dates and contractor details in writing.
- Do not assume a previous neighbour’s approval applies to your flat.
