Quick answer: To apply for an HDB renovation permit, first confirm whether your kitchen or bathroom works need approval, then engage an HDB-registered renovation contractor to submit the application with the required plans and work details. Do not start hacking, floor replacement, bathroom tile removal, plumbing rerouting, or major kitchen layout changes until the permit is approved. The permit is not paperwork for paperwork’s sake. It protects the flat, your neighbours, and your renovation budget.
You have got the BTO keys, and the flat is bare concrete with a decision list longer than expected. The kitchen and bathroom look like the fun parts of the renovation, until someone asks whether the wall, tiles, sink, pipes, and waterproofing are allowed.
How to apply HDB renovation permit step by step
The safest way to apply for an HDB renovation permit is to work backwards from the renovation scope. A light refresh may not need the same approval as hacking, floor replacement, or bathroom works. A contractor should not be guessing. The proposed work should be checked against HDB renovation guidelines before anyone starts.
| Step | What to do | Why it matters |
|---|---|---|
| 1. List the exact works | Separate kitchen, bathroom, plumbing, electrical, flooring, wall, and carpentry works | Permit needs depend on the actual work, not the room name |
| 2. Check HDB guidelines | Confirm which works need approval and which are not allowed | This prevents redesigns after the contractor has already quoted |
| 3. Engage the right contractor | Use an HDB-registered renovation contractor for renovation works | They should understand submission requirements and flat restrictions |
| 4. Prepare documents | Provide the floor plan, proposed work list, drawings, and relevant details | HDB needs enough information to evaluate the renovation scope |
| 5. Submit the application | The renovation contractor submits the application through HDB’s renovation e-Service | Approval must come before permit-controlled work starts |
| 6. Follow the approved plan | Display the permit where required and carry out only approved works | Changing the scope after approval can create compliance problems |
What kitchen renovation works may need a permit?
Kitchen permits usually matter when the work affects walls, floors, plumbing, gas, structural elements, or built-in features. Replacing loose furniture is different from changing the physical flat. Once the renovation touches the flat itself, slow down and check.
Common kitchen works to review include:
- Removing or altering walls for an open-concept kitchen
- Replacing floor finishes
- Changing wall finishes
- Relocating the sink or modifying water and sanitary pipes
- Changing gas works or hob-related connections
- Installing built-in cabinets that affect fixed services or clearances
If you are planning storage first, browse kitchen cabinets for Singapore homes after the layout is confirmed. Cabinet depth, door swing, sink position, hob position, and walkway space should be planned together, not treated as separate purchases.
What bathroom renovation works may need a permit?
Bathroom renovation needs more care because waterproofing, floor finishes, wall finishes, pipes, sanitary fittings, and drainage affect the flat below and the units around you. A bathroom leak is not just your problem once water reaches the neighbour’s ceiling.
Pay close attention to works such as:
- Replacing bathroom floor or wall finishes
- Removing existing tiles in a newer flat where restrictions may still apply
- Changing the toilet pan, wash basin, or shower area
- Installing long baths, shower trays, or similar sanitary fittings
- Rerouting water, sanitary, or gas-related works
- Changing bathroom doors, screens, or fixed fittings that affect safety or layout
For small bathroom upgrades that do not involve hacking or major works, start with practical items such as bathroom accessories and moisture-friendly storage. But if tiles, waterproofing, pipes, or fittings are involved, treat it as a renovation planning question first.
Kitchen and bathroom permit checks before you confirm the design
A beautiful drawing is not useful if it cannot be approved. Before finalising the design, ask your contractor which parts need HDB approval, which parts need licensed workers, and which parts should be avoided.
| Decision | Ask this before confirming | Practical note |
|---|---|---|
| Open kitchen | Is any wall being removed or altered? | Wall works need careful review because structural safety comes first |
| Sink relocation | Will water or sanitary pipes be changed? | Plumbing work should be checked before cabinets are fabricated |
| Hob placement | Does the hob position affect gas, electrical, or ventilation planning? | Confirm services before buying the hob |
| Bathroom tiles | Is tile removal allowed for this flat and this bathroom? | Newer flats may have restrictions, especially around bathroom finishes |
| Shower screen | Does the screen meet safety and installation requirements? | Glass, fixings, and clearances should be discussed early |
| Built-in storage | Will cabinet doors, appliances, or pipes clash? | Storage should support the renovation, not block access for servicing |
Who can submit the HDB renovation permit application?
For renovation works in an HDB flat, use a contractor listed in HDB’s Directory of Renovation Contractors. Your contractor should prepare and submit the renovation permit application, including the floor plan and proposed works where required.
The homeowner still owns the responsibility. Do not treat the permit as something only the contractor needs to care about. Ask what is being submitted, what is excluded, whether licensed workers are needed, and whether the approved scope matches the quotation.
What documents should you prepare?
The exact submission depends on the work, but you should prepare the basics before the application starts. This keeps the process cleaner and reduces back-and-forth with the contractor.
- Flat floor plan
- Detailed renovation work list
- Kitchen and bathroom layout drawings, where relevant
- Wall, floor, plumbing, electrical, and sanitary work details
- Appliance and fixture positions, especially hob, sink, basin, shower, and toilet areas
- Any professional endorsement if HDB requires it for the proposed work
If your kitchen plan includes a new hob, compare kitchen hobs only after the service points, counter cut-out, ventilation, and installation requirements are clear. Buying the appliance before checking the layout can create avoidable changes later.
What happens after HDB approves the renovation permit?
Once approval is granted, the renovation should follow the approved plan. Keep communication clear with the contractor, especially if you change tiles, shift fittings, alter cabinets, or revise the layout midway through the project.
Do not assume a small change is harmless just because it looks minor. Moving a basin, changing pipe routes, or altering a wall can affect the permit scope. If the change affects approved works, check before proceeding.
Renovation timing also matters. Noisy works and general works have rules, and neighbours will notice if hacking starts at the wrong time. The best renovation is the one that finishes properly without creating a complaint trail along the corridor.
How to plan furniture and storage around the permit
Permits affect more than walls and tiles. They also affect when you should order furniture, appliances, and storage pieces. If cabinet measurements depend on tile thickness, pipe boxing, or the final sink position, wait until those decisions are settled before ordering large items.
Use ready-made storage for flexible areas, and built-in solutions only when the renovation layout is locked in. For sink-zone organisation after the renovation, browse sink organisers that keep cleaning tools, sponges, and dishwashing items tidier without changing the fixed works.
Complimentary delivery and professional assembly come with qualifying orders, which is helpful when kitchen cabinets, storage pieces, and home essentials arrive after renovation handover. If something arrives damaged, the team at +65 6950-2657 sorts it locally, not through a returns form sent to an address outside Singapore.
When not to rush the permit application
Do not rush the application if your contractor has not finalised the actual work scope, if the kitchen layout keeps changing, or if the bathroom tile and waterproofing plan is unclear. A fast submission with weak details can slow the project down later.
Also pause if your plan depends on hacking a wall, moving major services, or changing bathroom finishes in a newer flat. These are the decisions where approval, safety, and long-term maintenance matter more than speed.
Final thoughts on how to apply HDB renovation permit
Learning how to apply HDB renovation permit is really about sequencing. Confirm the scope, check HDB rules, engage the right contractor, submit the correct details, wait for approval, then renovate according to the approved plan. For kitchen and bathroom works, that sequence is not optional. It is the difference between a smooth handover and an expensive redo.
A growing share of Mega Furniture's furniture range now comes from its own factories in Batu Pahat, Johor and Foshan, Guangdong, both operational since late 2025. Quality checks happen in-house before pieces ship to Singapore, where delivery and professional assembly are handled locally. It is not the whole range yet, but the programme is expanding through 2028.

You may need a permit for bathroom works involving floor or wall finishes, waterproofing, sanitary fittings, pipes, shower trays, or similar fixed works. Newer flats may also have restrictions on removing bathroom floor and wall finishes.
Can I apply for the HDB renovation permit myself?
For renovation works, your HDB-registered renovation contractor is usually the party that prepares and submits the application. As the flat owner, you should still check what is being submitted and make sure the work follows HDB guidelines.
Should I buy kitchen cabinets before the renovation permit is approved?
Do not confirm fixed kitchen cabinets too early if the layout depends on walls, pipes, sink position, hob position, or floor finishes. Wait until the renovation scope is clear so the cabinets fit the approved plan and final site measurements.
