Understanding Singapore Renovation Rules & Requirements
HDB Renovation Framework
HDB has strict guidelines to protect building structure and ensure safety for all residents. Before renovation begins, homeowners must understand which works require approval.
Hacking walls, changing floor finishes, shifting sanitary fittings, installing new windows and any major electrical rewiring require permits. HDB also regulates approved materials, working hours and the type of contractors allowed to perform works. Only HDB-licensed renovation contractors can carry out works inside a flat, and homeowners must ensure their chosen ID firm coordinates submissions correctly.
Understanding these rules avoids delays, failed submissions or costly reinstatement.
Condo Renovation Restrictions
Condo projects follow their Management Corporation Strata Title (MCST) rules, which differ across developments. Most condos restrict noise, working hours and heavy wet works. Homeowners must submit renovation plans for approval, and some materials may be restricted.
Common MCST Requirements
- Working hours allowed only on weekdays
- Noise limits for drilling and hacking
- Restrictions on wet works such as flooring retiling
- Lift padding, deposits and protection before works
- Approval required for structural or façade changes
Understanding these guidelines early ensures your condo renovation proceeds smoothly.
Timeline: How Long Renovations Typically Take
Different home types have different durations due to hacking, rectification and carpentry needs.
- BTO Timeline – Usually 6–10 weeks since no hacking is needed.
- Resale HDB Timeline – 10–14 weeks due to rewiring, plumbing and tile replacement.
- Condo Timeline – 6–12 weeks depending on MCST restrictions and wet works.
- Wet Works Duration – 2–4 weeks for tiling, waterproofing and masonry works.
- Carpentry Timeline – 3–5 weeks for fabrication and installation.
- Inspection & Handover – About 1 week for touch-ups and final checks.
