HDB Renovation Rules Every Homeowner Must Know

HDB renovation projects are subject to strict guidelines set by the Housing & Development Board. Failing to comply can result in hefty fines, reinstatement costs, and delays that blow your entire timeline. Here's what you need to know before you start.

What Requires an HDB Permit?

• Demolishing or hacking structural walls (including RC walls)
• Relocating your kitchen or bathroom
• Installing new windows or grilles
• Any work affecting common property

Work That Doesn't Need a Permit

Cosmetic updates like painting, laying new floor tiles over existing ones (in non-wet areas), replacing doors, and installing built-in furniture generally don't require permits — but always confirm with HDB's e-Enquiry portal.

Approved Contractor Requirement

All renovation works in HDB flats must be carried out by HDB-registered contractors. Hiring an unregistered contractor, even for minor work, puts you at legal risk.

Renovation Hours

Renovation work is only allowed on weekdays from 9am–6pm and Saturdays from 9am–1pm. No renovation is allowed on Sundays or public holidays. Noise-generating work (hacking, drilling) has stricter time limits.

Common Mistakes to Avoid

• Widening doorways without approval
• Installing floor-to-ceiling glass panels without calculating structural load
• Connecting water pipes to locations not approved in the permit
