HDB Renovation Permit for Carpentry: Do You Need One?

Many Singapore homeowners are unsure whether their carpentry project requires an HDB renovation permit. The answer depends on what's being done — and getting it wrong can mean having to redo completed work. Here's a practical guide.

What is an HDB renovation permit?

HDB requires homeowners to apply for a renovation permit before carrying out works that could affect the structural integrity of the flat, neighbouring units, or the estate's facilities. The permit is applied for through HDB's online portal, and approved contractors must carry out the work.

As a licensed HDB renovation contractor, WoodStudio.sg can apply for permits on your behalf when required.

Carpentry work that does NOT need a permit

Most standard carpentry work is permit-free:

  • Built-in wardrobes and bedroom furniture
  • Kitchen cabinets (upper and lower) — as long as you're not touching structural walls
  • TV consoles and feature walls (non-structural)
  • Shoe cabinets and foyer storage
  • Bookshelves and display cabinets
  • Study desks and home office furniture
  • Bathroom vanity cabinets (replacement or new installation)
  • Bed frames and headboards
  • Any freestanding or wall-mounted furniture that doesn't break walls

In short: if a carpenter is building, assembling, and installing furniture in your flat without drilling into load-bearing walls or altering the building structure, you almost certainly don't need a permit for the carpentry work itself.

Carpentry-adjacent work that MAY need a permit

The permit requirement typically kicks in when carpentry is combined with other trades:

  • Hacking/demolition works: If you're removing a wall (including non-structural partition walls) to create an open-plan kitchen or a walk-in wardrobe space, you need a permit for the hacking work. The carpentry that follows is permit-free.
  • Wet works in kitchen/bathrooms: Replacing floor or wall tiles, waterproofing — these need a permit. The carpentry (vanity, cabinets) doesn't, but the tiling does.
  • Gas works: Any changes to gas piping require a separate permit and licensed contractor.
  • Electrical works: New circuit wiring for integrated lighting in built-ins requires an electrical permit. A licensed electrician handles this separately.

HDB's approved contractor requirement

For works requiring a permit, only HDB-registered renovation contractors can carry out the work. WoodStudio.sg is a registered contractor. For permit-free carpentry, any licensed contractor can carry out the work.

Practical advice: tell your neighbours

Whether or not a permit is required, HDB guidelines recommend notifying your neighbours (above, below, and on both sides) at least 3 days before renovation begins. This is courtesy — and practically avoids complaints being filed with the managing agent.

All HDB renovation work must be completed within 1 month of permit approval. Work is only allowed on weekdays 9am–5pm and Saturdays 9am–1pm. No work on Sundays and public holidays.

Bottom line

For the vast majority of carpentry projects — wardrobes, kitchen cabinets, built-in storage, TV consoles — you do not need an HDB renovation permit. The carpentry itself is straightforward.

If you're planning a renovation that involves multiple trades (hacking, tiling, carpentry, electrical), let us know during consultation. We can help you understand which elements need permits and coordinate with the relevant contractors.
