Have you just received your keys to a new flat? Congratulations! Whether it’s a BTO 5-room renovation or planning a sleek 4-room BTO renovation design in Singapore, you need to follow specific rules set by HDB. BTO renovation Singapore has some rules to keep the building structure safe and ensure peaceful living for all residents.
Before you pick up a hammer or hire a contractor, make sure you're aware of what you want and what you can and cannot do.
Understanding BTO Renovation Rules in Singapore
HDB flats come with strict rules for a reason. Safety, comfort, and the integrity of the structure all depend on responsible planning. Before you begin your BTO renovation journey, get familiar with these key points:
You need a Renovation Permit
You can’t carry out major changes without HDB’s approval. Any hacking, re-tiling, or new window work needs a permit. Apply through a registered renovation contractor. The contractor will send the request to HDB and get your green light.
Follow the Three-Month Rule
Renovation must be done within three months of the date you collect your keys. This applies to new flats. So, whether you’re diving into a 4-room BTO renovation design or larger spaces, stick to the timeline.
Work Only During Approved Hours
Noise control is key. Contractors are allowed to work from:
● 9:00 AM to 6:00 PM (Weekdays and Saturdays)
● No noisy work is allowed on Sundays and public holidays
Plan your BTO renovation in Singapore around these timings to avoid fines or complaints.
Structural Restrictions You Cannot Ignore.
HDB flats are part of a bigger system. What you change can impact your neighbours. So, structural works have major restrictions.
No Hacking of Structural Walls
You can’t tear down any wall that holds weight. These are usually beams or thick walls in the centre. HDB may allow partial hacking, but only with approval.
Floors and Ceilings Have Limits
You can’t raise the floor beyond 50mm with cement screed. For ceilings, avoid false ceilings that block sprinkler systems or make inspection hard.
Bathrooms Have a Waterproofing Rule
If you want to retile your bathroom, you can only do it three years after moving in. This prevents damage to waterproof layers applied by HDB.
Rules for Doors, Windows, and Grilles
Small changes make a big difference in design, but they must be within the rules.
Door Frames: Only Internal Ones
External doors and frames must stay as they are. You can only change internal door frames. For fire-rated doors near staircases, get HDB’s nod.
Windows and Grilles: Stick to the Standard
HDB has a fixed window and grille design for each block. You can’t change the type, size, or colour. Use contractors approved by HDB.
Gate Replacements Are Permitted
You can change your metal gate, but only if it meets fire safety standards. Inform your town council before doing so.
Plumbing and Electrical Works
Good design also means safe wiring and plumbing. Here are the key things to note:
Water Pipes Must Stay in Place
You can’t move water pipes around unless it's approved. Any changes to the bathroom layout must follow strict rules. Pipes under floors or concealed walls are a big no.
Use a Licensed Electrician
All electrical work must follow the Singapore Standard CP5. Engage only a licensed electrical worker. Major changes, like rewiring, need a permit from SP Services.
Flooring, Wall Works, and Finishes
Planning to give your flat a new look? Ensure your BTO renovation Singapore plans follow HDB flooring and wall finish rules.
Floor Finishes: No Overlays Without Care
Overlaying tiles over existing ones is allowed. But make sure:
● Tiles are not uneven
● The new layer doesn’t exceed the floor height limit
Wall Painting Is Allowed
You can paint your walls any colour, as long as it doesn’t affect the neighbour’s side in corridor-facing flats. Avoid textured finishes that trap moisture.
Wall Cladding Needs Approval
If you're adding stone, wood, or tile cladding to walls, get HDB’s permission. Heavy finishes can fall and injure someone.
Air-Con and Ceiling Fan Installation Rules
Cooling your space is a must in Singapore. But do it the right way.
Use HDB-Approved Air-Con Brackets
Use only approved brackets for external air-con units. These brackets must be installed by BCA-trained workers.
Secure Ceiling Fans Properly
Make sure ceiling fans are safely anchored to concrete ceilings. Avoid mounting them on false ceilings or plasterboards.
Avoiding Common BTO Renovation Mistakes
Even the best plans can go wrong. These common mistakes often delay BTO renovation projects or lead to penalties.
Hiring Non-HDB-Registered Contractors
Always check the Directory of Renovation Contractors (DRC). Only engage firms listed under it. Unregistered firms may not know the HDB rules well.
Ignoring the Guidelines for BTO 5 Room Renovation
Bigger flats may tempt you to make bold changes. Avoid creating open kitchens or removing walls without a permit in a BTO 5-room renovation. It’s still an HDB flat.
Going Overboard on Design for 4 Room BTO Renovation
Balance style with safety. Use built-in furniture wisely. Avoid designs that block airflow or natural light.
Penalties for Breaking HDB Renovation Guidelines
Breaking rules can cost you. HDB may:
● Issue a Stop Work Order
● Fine you
● Ask you to restore the changes at your own cost
If neighbours report your renovation works, HDB will step in fast.
Tips to Get Your BTO Renovation Approved Smoothly
Want a hassle-free process? Follow these steps:
● Prepare all layout plans clearly
● Choose contractors from the HDB directory.
● Submit documents early
● Avoid last-minute changes
Whether you’re planning a stylish 4-room BTO renovation design or a sleek 5-room BTO renovation, these tips will help you breeze through.
What You Must Remember
● Apply for permits before starting major work.s
● Stick to the three-month renovation window.
● Never hack structural walls or alter bathroom floors too soon.
● Use licensed and HDB-registered professionals only.
● Respect noise restrictions and neighbour rights
