HDB Renovation Guide Singapore: Renovation Control Rules 2006
The one document every flat owner should read before a single wall comes down is the Renovation Control Rules 2006. This HDB Renovation Guide Singapore breaks down what those rules mean for your project in 2025 and 2026, what permit works actually cover, and the fines that hit when people ignore them. Know the line before your contractor crosses it.
Why the Renovation Control Rules 2006 exist
HDB flats share structure and walls with neighbours above, below, and beside you. One bad hack can weaken a whole block. The rules exist to keep that shared structure safe.
They are not suggestions. They sit under HDB's Renovation Control framework, and they decide who may carry out works and what needs approval first.
What the rules say about your contractor
Permit works must be done by contractors listed in the Directory of Renovation Contractors (DRC). An HDB-approved contractor on that list is the only party who can apply for your HDB renovation permit.
If a firm is not on the DRC, it cannot submit permit applications for you.
Works that need a permit
The rules list specific jobs that require HDB approval before work starts:
- Hacking of non-structural walls
- Toilet tile changes (for BTO flats, not within the first 3 years; overlay is allowed)
- Windows and grilles, which must be HDB-approved and fitted by BCA-trained workers
- Repositioning of doors
- Rewiring beyond approved points, done by a Licensed Electrical Worker under EMA rules
- Plumbing works, carried out by a PUB-licensed plumber
- Structural works, signed off by a Professional Engineer registered with PEB
Each of these touches the building's safety or services. That is why none of them can go ahead on a handshake.
Works that skip the permit
Plenty of renovation work needs no permit at all. You can paint, put up wallpaper, install carpentry, lay vinyl overlay flooring, fit light fittings, and hang curtains or blinds without HDB approval.
I tell owners to treat this list as their free zone.
What is always prohibited
Some things are never allowed, permit or not:
- Hacking structural walls, beams or columns
- Removing or altering RC ledges
- Relocating toilets or kitchens
- Changing the facade
- Adding floor loads above 150kg per square metre
These are hard limits. No amount of money buys permission for them.

Where the HDB Renovation Guide Singapore rules get strict: penalties
The fines are written into the rules and they bite. Structural offences carry a penalty of up to S$5,000 plus full reinstatement of the flat to its approved layout.
Using an unlicensed person for permit works can also draw a fine of up to S$5,000. Off-hours works pull a separate penalty of up to S$1,000.
Plan the approval window early
A permit can take up to 3 weeks, though simple ones clear in 3 to 7 days. The permit is valid for 3 months for BTO flats and 1 month for resale flats.
Get the rules straight before you brief your contractor. Pull the DRC list, match your job to the permit it needs, and refuse anything on the prohibited list no matter how small it sounds. Your flat, your fine, your call.
