Before you sign a quotation for your HDB flat, one quick check can save a lot of trouble: is the firm on the HDB DRC contractor list? DRC stands for the Directory of Renovation Contractors, the list HDB keeps of firms registered to carry out renovation works in HDB flats. This guide explains how to verify a contractor’s DRC status, what being listed actually means, what it does not guarantee, and what to do if your contractor is not on the list.
This is general information. HDB’s rules and its directory can change, so always confirm current requirements on the HDB website or with your HDB branch.

What the Directory of Renovation Contractors Is
HDB regulates renovation in its flats because works can affect structural safety, waterproofing, neighbours and common property. To help with this, HDB maintains a directory of renovation firms that have registered with it. Firms on the directory are expected to know HDB’s renovation guidelines and to apply for the necessary permits on behalf of flat owners.
In practice, the DRC matters because:
- Many works need an HDB renovation permit. Examples commonly include hacking walls, replacing floor finishes in certain areas and some bathroom works. A DRC-registered contractor is generally the one who applies for that permit for you.
- HDB can act against listed firms. Registered contractors who breach renovation rules can face penalties from HDB, including suspension or removal from the directory, which gives them a strong incentive to follow the rules.
- It is a baseline filter. The directory is a starting point for shortlisting, not a full quality guarantee.
For a fuller overview of which works need permits, see HDB renovation rules and permits.
How to Check the HDB DRC Contractor List
The check takes a few minutes and is free.
- Get the firm’s exact registered name and UEN. The UEN (Unique Entity Number) is the business registration number issued through ACRA, Singapore’s company registry. Ask the contractor for it, and check it appears on the quotation.
- Go to the official HDB website. Look for the Directory of Renovation Contractors under the renovation section for flat owners. Use only the official HDB site, not a link sent by the contractor.
- Search by company name. Try the full registered name, and also a shorter version, since trading names on shopfronts and social media may differ from registered names.
- Check the status shown. Confirm the firm appears as currently registered and note any information HDB displays, such as suspension or debarment records.
- Match the details. Make sure the name and particulars on the directory match those on the quotation and contract. A similar-sounding name is not the same firm.
- Screenshot the result with the date, and keep it with your renovation records.
If you cannot find the firm, ask the contractor directly. A genuine DRC firm should be able to explain how it appears on the directory.
What DRC Status Means and What It Does Not
Being listed is useful, but homeowners often read too much into it. Here is a quick comparison.
| What DRC status suggests | What it does NOT guarantee |
|---|---|
| The firm is registered with HDB to do works in HDB flats | Good workmanship or finishing quality |
| It can apply for HDB renovation permits | Fair pricing or a competitive quotation |
| HDB can take action against it for rule breaches | That the firm will finish on time |
| It is expected to know HDB renovation guidelines | Protection of your deposit if the firm closes down |
In other words, DRC status covers regulatory compliance with HDB rules. It does not replace your own checks on quality, price and financial reliability. If things do go wrong, our guide to handling renovation disputes with contractors walks through your options.
Other Checks to Make Alongside the DRC List
Treat the DRC check as one item on a short due diligence list.
- ACRA business profile. You can buy a business profile through Bizfile, ACRA’s online portal, to see when the company was registered and whether it is still live.
- Accreditation schemes. Some renovation firms hold CaseTrust accreditation, a scheme run by the Consumers Association of Singapore (CASE) that includes deposit protection elements for accredited firms. Check the CASE website for the current list and what the scheme covers.
- Specialist registrations. Certain works need specialist approvals. For example, window installation in HDB flats must be done by contractors approved for that work, and electrical works should be done by a licensed electrical worker. Plumbing and gas works have their own licensing requirements. If your project includes these, ask who will do them and check their credentials. Our guide to replacing windows in an HDB flat explains the window side.
- Past work and reviews. Ask to see completed projects in HDB flats similar to yours and read reviews from several sources.
- A clear written contract. It should list every item of work, materials, payment schedule, timeline and warranty terms.
- Sensible payment terms. Be wary of firms asking for a very large upfront deposit before any work starts. Staged payments linked to completed milestones are a common safeguard.
What If Your Contractor Is Not on the List?
Not every firm working in homes is a DRC contractor, and not every job needs one. Small jobs such as painting, installing loose furniture or minor fixes may not require an HDB permit. However, if your works do need a permit, the safest route is to use a DRC-registered firm.
Points to consider:
- Ask why. The firm may be newly set up, recently lapsed, or using a subcontractor arrangement. Get the explanation in writing.
- Check who applies for the permit. If a non-DRC firm says it will “handle the permit”, ask under which registered contractor’s name, and verify that firm on the directory.
- Understand your exposure. As the flat owner, you are responsible for renovation works in your flat. Unauthorised works can lead to HDB requiring rectification at your cost, and you may face penalties. Check HDB’s current guidance for specifics.
- Do not let a deal override the rules. A lower quotation from an unregistered firm can cost more if works must be redone.
Keeping Records During Your Renovation
Once you have chosen a DRC contractor, keep a simple paper trail:
- the dated DRC screenshot and ACRA business profile
- the signed quotation and contract
- a copy of the HDB renovation permit, which is often displayed at the flat during works
- payment receipts tied to each milestone
- photos of the flat before, during and after works
These records help if you need to raise a defect, claim under a warranty or resolve a dispute, and they are handy when you sell the flat later.
Quick Checklist Before You Sign
- The firm’s registered name and UEN match the quotation.
- It appears as registered on HDB’s Directory of Renovation Contractors today.
- Specialist works (windows, electrical, plumbing, gas) are done by suitably approved or licensed workers.
- The contract lists works, materials, timeline, payments and warranty.
- You know who will apply for the HDB permit and when.
A few minutes on the HDB DRC contractor list, plus these extra checks, gives you a much firmer footing before the hacking starts. For broader advice on comparing firms, read choosing a renovation contractor.
