For many Singapore homeowners, especially first-time BTO owners, renovating a new HDB flat can feel overwhelming. From collecting your keys to finally moving in, the process involves multiple stages, approvals, and coordination with different professionals.
This complete guide walks you through the typical HDB renovation timeline in Singapore, helping you plan properly, avoid delays, and move into your new home with confidence.
Phase 1: Key Collection & Initial Inspection (Week 0–1)
Once you collect your keys from HDB, the renovation journey officially begins.
What to Do
- Inspect walls, floors, doors, and windows
- Check for defects and uneven surfaces
- Test water supply and drainage
- Verify electrical points and switches
- Take photos for documentation
Important Tip
Report any defects to HDB immediately. Rectifying them before renovation saves time and prevents disputes later.
Phase 2: Renovation Planning & Budgeting (Week 1–3)
Proper planning is the foundation of a smooth renovation.
Key Tasks
- Decide on layout changes
- Confirm carpentry requirements
- Select materials and finishes
- Set renovation budget
- Shortlist renovation firms
Budget Guide (Typical Range)
| Flat Type | Average Renovation Cost |
|---|---|
| 3-Room | $25,000 – $40,000 |
| 4-Room | $35,000 – $60,000 |
| 5-Room | $45,000 – $80,000 |
Phase 3: Engaging Your Renovation Contractor (Week 3–4)
Choosing the right contractor is critical for quality and peace of mind.
What to Check
- HDB Registered Renovation Contractor (RRC) status
- Company track record
- Portfolio and reviews
- Detailed quotation
- Warranty terms
Best Practice
Avoid choosing solely based on price. Evaluate transparency, experience, and communication quality.

Before work begins, finalise all design details.
This Stage Includes
- 3D drawings and layouts
- Material confirmation
- Cabinet dimensions
- Lighting and power point planning
- Colour schemes
Why This Matters
Finalising details early prevents costly variation orders later.
Phase 5: HDB Renovation Permit Application (Week 5–7)
Most renovation works require approval from HDB.
Common Permit Items
- Hacking of walls or tiles
- Plumbing modifications
- Electrical rewiring
- Window replacement
- Floor screeding
Processing Time
HDB approval usually takes 1 to 2 weeks.
Only licensed contractors can submit permit applications.

What Happens

- Factory fabrication
- Quality inspection
- Delivery and installation
Time Required
Typically 3 to 6 weeks depending on design complexity.
Phase 8: Final Touch-Ups & Quality Inspection (Week 14–17)
Before handover, all works should be carefully inspected.
Checklist

- Door and drawer movement
- Paint finish quality
