It’s exciting to finally move into your new flat, be it a BTO or a resale HDB, and start adding your personal touch to make it feel more like home. If you’re thinking about doing some renovation work for your BTO or resale HDB flat, here’s all you need to know before contacting a contractor or Interior Design firm. 

BTO flats typically require minimal renovation

BTO flats are brand new and built to current standards, so they don’t require that much work to make them livable. Basic necessities like flooring, bathroom fittings, and kitchen fixtures are usually included.

However, while you can do with minimal upgrades, some BTO owners still choose to do a complete overhaul, which can make the renovation costs comparable to or even higher than those for resale flats. 

Resale HDB flats often require more extensive renovation

Resale flats often require more extensive renovation due to wear and tear, outdated fixtures, and often: so it can suit you and your family’s tastes. This is why the starting cost for renovating a resale flat is generally higher.

How to get a HDB renovation permit?

Application form for HDB renovation permit

1. Engage a HDB-registered renovation contractor

You can only engage an HDB-registered contractor to renovate your BTO flat or resale HDB. This is a mandatory requirement to ensure that all renovation works comply with HDB’s safety and quality standards.

You cannot legally renovate your BTO or resale HDB if they are not registered with HDB; if you do, you will face penalties from HDB and might be required to undo or rectify any renovation work at your own expense. 

How to ensure your contractor is HDB-registered

  • Check HDB’s directory: HDB maintains a directory of registered renovation contractors on its website. so you can verify that your chosen contractor is listed in this directory before hiring them.
  • Request for proof: Ask your contractor to provide proof of their HDB registration. This can include their registration certificate or HDB license number.
  • Consult with HDB: If in doubt, you can always consult with HDB directly to confirm the registration status of your contractor. This ensures that you are hiring a compliant and qualified professional for your HDB renovation.

2. Discuss and plan renovation works

Collaborate with your contractor to discuss and plan the renovation works. Make sure the plans comply with HDB’s regulations.

3. Submit renovation permit application

Your contractor will submit a renovation permit application to HDB on your behalf, including detailed plans and descriptions of the proposed renovation works.

The required documents typically include the contractor’s credentials, detailed renovation plans, and any necessary structural or design modifications.

4. Await approval

HDB will then review the application to ensure the proposed works comply with their guidelines. The review process may take a few weeks. They may also request additional information or modifications to the plans if they do not fully comply with the guidelines.

5. Receive renovation permit

Once HDB approves the renovation works, you will receive a renovation permit. Ensure that the permit is visibly displayed in your flat during the renovation period.
