HDB Renovation Timeline Planner
Enter your dates to see HDB's deadlines for your flat, the hours your contractor can work, and when to book the clean before you move in. Every rule comes from HDB's own pages, linked below.
Plan your dates
How long does an HDB renovation take?
HDB does not say how long a renovation takes, but it sets a deadline. Approved renovations must be finished within 3 months of the permit date in a newly completed block, within 1 month in an existing block, and within 2 weeks if you are only doing window works (HDB: important information on renovations). Ask your contractor for a finish date that sits inside that window.
HDB renovation hours
General renovation can only be carried out from 9am to 6pm on weekdays and Saturdays. No renovation is allowed on Sundays and public holidays.
Restricted renovation, such as demolishing walls, removing wall or floor finishes, cutting tiles and heavy drilling, can only be carried out from 9am to 5pm on weekdays. It is not allowed on Saturdays, Sundays, public holidays, or the eves of New Year's Day, Chinese New Year, Deepavali, Hari Raya Puasa and Christmas Day.
The planner checks your dates against the public holidays published by the Ministry of Manpower for 2026 and 2027 (MOM: public holidays).
New flats: report defects first
Newly completed HDB flats have a 1-year Defects Liability Period from the day you collect your keys. HDB asks you to report defects within 1 month of key collection and before your renovation starts, and usually takes less than 2 weeks to complete the repair. If your renovation cannot wait, HDB can fix defects during the renovation or after it (HDB: rectification of defects in new flats).
When to book the clean
Book the clean for after your contractor's last day, once the renovation debris has been cleared. We suggest booking about 1.5 weeks ahead. We normally send 1 to 3 cleaners, and a clean usually takes around 3 to 6 hours, or up to 9 hours for larger homes, depending on the condition of the home. Slots run from 9am to 1pm or 2pm to 6pm.
See our price list for your flat type, read how to prepare your HDB for the clean, or see what a move-in clean covers. You can also read about HDB post renovation cleaning prices and how a job runs. To see what the clean involves from start to finish, read cleaning after renovation: what to expect.
What this planner does not cover
- It does not estimate how long your renovation will take. Only your contractor can tell you that.
- It uses HDB's rules only. For a condo or landed home, check your own renovation rules before you plan.
- Holiday dates are checked for 2026 and 2027 only.
- Your permit and HDB's current guidelines always come first.
