HDB Renovation Guide Singapore: Choosing a Contractor

This HDB Renovation Guide Singapore shows you how to pick a contractor who keeps your reno legal in 2025 and 2026. The takeaway: only hire someone in HDB's Directory of Renovation Contractors, or you risk a S$5,000 fine and a forced rebuild. Check the list before you talk money.

Choosing a contractor

In Singapore, permit works must be done by a contractor in HDB's Directory of Renovation Contractors (DRC). This is law under the Housing & Development (Renovation Control) Rules 2006. Hire outside that list and you're breaking the rules from day one.

The DRC exists so owners don't get cowboy operators. Every listed firm has met HDB's standards. Using an unlisted one isn't a small risk. The penalty for using an unlicensed contractor goes up to S$5,000. I always tell clients: the cheapest quote is expensive if it's illegal.

Beyond the listing, you want a team that communicates in plain English and shows you past flats like yours. A good HDB-approved contractor walks you through the permit steps instead of waving them away.

How to verify a contractor

Start with the official check. Confirm the firm is in the DRC on HDB's records. Then dig into the human side. Ask for flats they've done that match your type and age, BTO or resale.

• Confirm DRC listing with HDB directly, not just a screenshot.
• Ask for a track record of similar flats and visit one if you can.
• Read the warranty terms, usually about 1 year on carpentry and fittings.




• Get a transparent quote that breaks cost down by trade.
• Check they coordinate the right pros: LEW for rewiring, PUB plumber, PE for structure.

The quote should name who handles what. Rewiring past existing points needs a Licensed Electrical Worker under EMA. Plumbing changes need a PUB-licensed plumber. Structural work needs a PE from PEB. A solid contractor lines these up for you instead of leaving you to chase them.

Red flags

Some signs are loud. Others are quiet. Watch for quotes that show one lump sum with no item breakdown. That hides where your money goes and makes disputes ugly later.

Walk away if they say permits aren't needed for works that clearly are. Hacking walls, changing toilet tiles, or replacing windows all need approval. A contractor who hand-waves that is either clueless or planning to skip it, and you pay the fine, not them.

Pressure tactics are another tell. "Book today or the price goes up" is a sales trick, not a build plan. So is a vague scope where carpentry dimensions or board grades aren't stated. And if they refuse to put the 1-year warranty in writing, that's your answer.

Pick from the DRC, verify the track record, and read the quote line by line. A proper HDB-approved contractor handles your permit and brings in the right licensed pros. Do that homework and your flat gets done right the first time.
