HDB renovations come with a specific set of rules that many homeowners only discover after making costly mistakes. Here is a clear breakdown of what carpentry works are allowed, what needs approval, and what is strictly prohibited.

What You Can Do Without Approval

The following carpentry works are generally permitted without prior HDB approval:

  • Installing built-in wardrobes, cabinets, and storage units
  • Kitchen cabinet replacement (no structural changes)
  • Loose furniture and shelving installation
  • TV console and entertainment unit installation
  • False ceiling installation (non-structural, within height limits)
  • Door replacement (same opening, no structural changes)

💡 Even without formal approval, all works must comply with HDB renovation guidelines. Your contractor is responsible for ensuring compliance.

What Requires HDB Approval or Notification

  • Removal or modification of any wall (structural or non-structural)
  • Installation of new internal doors or openings
  • Works affecting the building facade or common areas
  • Any works near party walls (walls shared with neighbours)

What Is Strictly Prohibited

  • Hacking or modifying structural walls, columns, or beams
  • Removing reinforced concrete elements
  • Altering the flat's external appearance
  • Works that affect the structural integrity of the building

⚠️ HDB carries out random renovation checks. Unapproved structural works can result in mandatory reinstatement at your cost — often far exceeding the original work value.

Renovation Period Restrictions

HDB renovation works involving hacking, drilling, and other noisy activities are restricted to:

  • Monday to Friday: 9am – 6pm
  • Saturday: 9am – 1pm
  • No works on Sundays and public holidays

Engaging A Reliable Contractor

Always work with contractors who are familiar with HDB guidelines. An experienced contractor will advise you upfront on what is possible, handle any required notifications, and ensure your renovation passes inspection without issues.
