HDB Renovation Guide Singapore: DIY or Hire a Pro
Knowing what you can touch yourself saves money, and knowing what needs a licensed pro saves you from fines. This HDB Renovation Guide Singapore sets out the line between a weekend DIY job and works that must go through an HDB-approved contractor. Get this right and your reno stays legal and safe.
DIY or hire a pro. What homeowners can legally/safely do themselves
About 80% of Singapore residents live in HDB flats, and plenty of owners want to pitch in. The good news is HDB lets you do a fair bit without a permit. The bad news is the line is firm, and crossing it is costly.
My rule: if it changes structure, water, power, or the building envelope, call a pro. If it sits on the surface and comes out cleanly, you can likely do it yourself.
What you can DIY. Painting, wallpaper, vinyl overlay (no hack), curtains/light fittings, furniture
These works need no HDB permit and are safe for most owners:
- Painting and wallpaper
- Vinyl overlay flooring with no hacking, since the old tile stays
- Curtains and blinds
- Light fittings you swap at existing points
- Free-standing furniture and loose items
Vinyl overlay is the most popular DIY win. It goes over your existing tile, so no permit, no dust, and you can do a room in a weekend. Just clean the floor well first or it will bubble.
Carpentry like wardrobes and TV consoles also needs no permit, but building it yourself is harder. Most owners buy these from a carpenter rather than make them. That is allowed without a permit, just not strictly DIY.
What needs pros & permits. Hacking, rewiring (LEW), plumbing (PUB), windows (BCA), structural (PE); risks of going unlicensed
These works must go through licensed people under the Renovation Control Rules 2006:
- Hacking non-structural walls, done by a DRC-listed contractor
- Rewiring beyond existing points, by a Licensed Electrical Worker under EMA
- Plumbing and sanitary changes, by a PUB-licensed plumber
- Windows and grilles, by a BCA-trained window contractor using HDB-approved designs
- Any structural change, by a Professional Engineer registered with PEB
The risks of skipping this are not small. Using an unlicensed contractor carries a fine up to S$5,000. Unauthorized structural work can cost S$5,000 plus mandatory reinstatement. Working outside permitted hours adds up to S$1,000.
Noisy hacking and drilling are only allowed 9am to 5pm on weekdays. General works run 9am to 6pm weekdays and Saturdays. Nothing on Sundays or public holidays.
Windows deserve a special note. Since 2011, HDB requires safety restrictors on openable windows after fatal falls. You must keep them maintained, and only a BCA-trained contractor should fit or service them.
Pick your battles. Paint the walls and lay vinyl yourself, but let the DRC contractor hack, the LEW rewire, and the PUB plumber handle pipes. The permit, usually 3 to 7 days for simple cases, is the receipt that proves it was done right.
