The HDB Directory of Renovation Contractors (DRC)
Engaging an HDB-registered contractor isn't optional—it's a legal requirement under the Housing & Development (Renovation Control) Rules. The DRC system ensures contractors understand HDB regulations and can handle permit applications properly.
However, DRC registration is a 'license to operate,' not a quality guarantee. HDB explicitly states they don't endorse workmanship or mediate disputes. Your due diligence remains critical.
Verifying Contractor Registration
Always verify your contractor's current status before signing any agreement:
Check DRC Status Online
Visit HDB InfoWEB's DRC portal and search by company name or registration number.
Tip: Screenshot the verification page with date for your records.
Verify Registration Validity
Ensure registration is 'Active' and check expiry date. Avoid contractors near expiry without confirmed renewal.
Tip: Registration expires every 3 years and requires renewal.
Review Demerit Points
Check accumulated demerit points over past 24 months. Be cautious if approaching 24-point suspension threshold.
Tip: Ask contractors with 10+ points to explain the violations.
Check Infringement History
Review types of past violations. Pattern violations indicate systemic issues.
Tip: Avoid contractors with repeated same violations—shows no improvement.
Understanding the Demerit Point System
HDB's Demerit Point System (DPS) tracks contractor compliance. Understanding this system helps you assess contractor reliability:
| Violation Type | Demerit Points | Examples |
|---|---|---|
| Minor Administrative | 3-6 points | Late submission, incomplete documents |
| Renovation Violations | 6-12 points | Exceeding permitted hours, improper debris disposal |
| Safety Violations | 12-18 points | No safety equipment, dangerous practices |
| Major Infringements | Immediate suspension | Unauthorized structural works, false declarations |
24 points in 24 months = 1-year suspension from DRC
Red Flag: High Demerit Points
Contractors with 15+ demerit points face suspension risk. If suspended mid-renovation, you'll need to engage another contractor at additional cost. Always check points before signing contracts.
Specialist Requirements
Certain renovation works require licensed specialists beyond your general contractor:
| Specialist Type | Required For | Licensing Body | Verification Method |
|---|---|---|---|
| PUB Licensed Plumber | All bathroom/toilet works | PUB | PUB website verification |
| Licensed Electrical Worker | Electrical installations | EMA | EMA license check |
| BCA Window Contractor | Window replacement | BCA | HDB approved list |
| Professional Engineer | Complex structural works | PEB | PE Board registry |
| Gas Service Worker | Gas pipe relocation | EMA | EMA certification |
Owner vs Contractor Responsibilities
Understanding the legal division of responsibilities protects you from liability:
| Aspect | Owner Responsibility | Contractor Responsibility |
|---|---|---|
| Legal Liability | Ultimate responsibility for all works | Execution within regulations |
| Permit Application | Authorize and verify accuracy | Prepare and submit via APEX |
| Compliance | Ensure no prohibited works | Advise on regulations |
| Documentation | Provide ownership proof, sign forms | Compile technical documents |
| Penalties | Bear all fines and penalties | May face DRC suspension |
| Reinstatement | Pay for required reinstatement | Execute reinstatement works |
Best Practices for Contractor Management
Protect yourself with these contractor management strategies:
- Document all permit-related discussions in writing
- Include permit approval as a contract milestone
- Withhold 10% payment until permit obtained
- Specify who pays for rejection-related delays
- Include clause for contractor change if permit repeatedly rejected
- Require contractor to notify you within 24 hours of any HDB communication
- Get written confirmation that all specialists are properly licensed
CaseTrust Accreditation
Consider CaseTrust-accredited contractors for additional protection. They offer S$30,000 deposit protection and formal dispute resolution channels, though they typically charge 10-15% more.
When to Change Contractors
These situations warrant immediate contractor replacement:
- DRC registration expired or suspended
- Accumulated 20+ demerit points (near suspension)
- Multiple permit rejections due to documentation errors
- Proposes prohibited works despite warnings
- Cannot provide proper specialist certifications
- Refuses to put permit commitments in writing
- Has pattern of similar violations in DRC record
Contractor Change Costs
Changing contractors mid-permit can cost S$2,000-5,000 in duplicate work, new deposits, and delays. However, this is preferable to proceeding with an incompetent contractor who may cause S$10,000+ in compliance issues.
