How do I check if my contractor is HDB-licensed?

Visit HDB's Directory of Renovation Contractors at services2.hdb.gov.sg and search directly. Don't rely on screenshots or PDFs the contractor provides. You can also verify company registration with ACRA at bizfile.gov.sg.

What should be included in a renovation contract?

A comprehensive contract should include: detailed scope of works with brand specifications, itemised pricing, payment schedule tied to milestones, timeline with completion date, variation order procedures, defects liability period terms, and insurance/licence information.

How much does an HDB renovation cost in Singapore?

Costs vary significantly based on flat size, scope, and finishes. Get detailed quotations from 3-4 firms and compare itemised breakdowns. Add 15-20% contingency on top of any quote.

How long does an HDB renovation typically take?

Most comprehensive HDB renovations take 8-12 weeks, depending on scope, permit requirements, and external factors. Add 2-4 weeks buffer to any estimate, and more if spanning Chinese New Year.

What permits do I need for HDB renovation?

Permit requirements depend on specific works. Hacking walls, floor slab alterations, and toilet/kitchen layout changes typically require permits. Your renovation firm should handle all applications.

What are the permitted renovation hours in Singapore?

General renovation: 9am-6pm weekdays and Saturdays. No work on Sundays or Public Holidays. Noisy works (hacking, drilling): 9am-5pm weekdays only. Contractors must give neighbours 5 days written notice before starting.

Can I replace my bathroom tiles in a new BTO?

HDB imposes a 3-year restriction on replacing bathroom tiles from TOP date. This protects the waterproofing membrane. Replacing tiles within this period voids your warranty. You may lay new finishes over existing tiles using adhesive.

What is the Defects Liability Period (DLP)?

The DLP is a contractual term (not an HDB requirement) specifying the period after handover during which your contractor must rectify defects at no cost. Industry standard is 5 years for waterproofing and 12 months for general works. Always confirm specific coverage in your contract before signing.

What works are not allowed in my HDB flat?

Prohibited works include: hacking reinforced concrete (walls, columns, beams, slabs), exceeding 150kg/sqm floor load, raising floor level beyond 50mm, enclosing balconies, modifying Household Shelters, and any external facade changes.

How much do renovation mistakes cost to fix?

Fixing renovation mistakes typically costs $5,000 to $30,000, depending on severity. Permit violations requiring reinstatement can exceed the original renovation cost. Prevention through proper planning costs nothing.
