The HDB MOP, or minimum occupation period, is the time you must physically live in your flat before you can sell it on the open market, rent out the whole flat or buy private property. It is five years for most flats and ten years for Plus and Prime flats, counted from the day you take possession. Time you were not living there does not count.
Here is how the rules work in 2026, what the MOP blocks, and what you can still do while it runs.
How Long Is the HDB MOP?
The length depends on how and when you bought, according to HDB’s conditions after buying a new flat and its page on acquiring private property.
| How you bought | MOP |
|---|---|
| New or resale unclassified flat (sold before the October 2024 sales exercise) | 5 years |
| New or resale Standard flat | 5 years |
| New or resale Plus or Prime flat, including PLH flats sold before October 2024 | 10 years |
| DBSS flat from a developer | 5 years |
| Fresh Start Housing Scheme flat | 20 years |
Selective En bloc Redevelopment Scheme (SERS) flats have their own rules, which depend on when the site was announced. Your MOP date on HDB’s dashboard is the one that counts.
Two points catch people out. First, the 10-year MOP follows the flat, so a resale buyer of a Plus or Prime flat starts a fresh 10 years. Second, the classification only applies to flats launched from October 2024; older flats are unclassified and keep the 5-year rule.
How HDB Counts the MOP
The clock starts when you take possession: key collection for a new flat, or the resale completion date for a resale flat. HDB then excludes any time you did not live there, for example while the whole flat was rented out with approval, or while there was an infringement of the lease.
For buying private property, HDB counts from possession up to the earlier of the date you exercise the Option to Purchase or the date you sign the sale and purchase agreement. That applies even if the private home is still under construction. Signing a day early can make the purchase a breach.
Our MOP and SSD date calculator works out the date from your key collection or completion date. It cannot see any non-occupation periods, so check the result against your HDB record.
The short version: The MOP is 5 years for unclassified and Standard flats and 10 years for Plus and Prime flats. Until it ends, you cannot sell on the open market, rent out the whole flat, apply to buy another HDB flat or buy private property. You can still rent out spare rooms with HDB’s approval.
What You Cannot Do Before the MOP Ends
HDB lists four things that must wait. All the people listed in the flat are bound, not just the owners.
- Sell the flat on the open market. HDB inspects flats in every resale. If there are signs the flat was not lived in, it withholds the application and investigates.
- Rent out the whole flat. This is only allowed after the MOP, for Singapore Citizen owners, with HDB’s approval.
- Apply for an HDB Flat Eligibility (HFE) letter, which you need to buy another HDB flat. Core members also cannot apply to buy an Executive Condominium from a developer.
- Buy private residential property, in Singapore or overseas. Holding property on trust for someone else, or being the beneficiary of such a trust, is also not allowed.
Not living in the flat during the MOP is itself an infringement. MyNiceHome says enforcement ranges from a financial penalty to compulsory acquisition of the flat.
What You Can Still Do During the MOP
- Rent out spare bedrooms. Owners of 3-room or bigger flats may do this at any time after key collection, with HDB’s approval, as long as they keep living in the flat. 3Gen flat owners must wait until the MOP ends. Our guide to renting out an HDB flat or room covers the caps and the tax.
- Make a voluntary CPF housing refund to rebuild your Ordinary Account (see our guide to the voluntary housing refund).
After the MOP: Plus and Prime Flats Are Different
When a Standard or unclassified flat passes its MOP, the main restrictions lift. Plus and Prime flats keep tighter rules for good:
- No renting out the whole flat, even after 10 years. Spare rooms are still allowed with approval.
- Subsidy recovery on sale. When you sell a Plus or Prime flat bought from HDB, you return a percentage of the resale price or valuation, whichever is higher. The percentage is set when the project is launched. Resale Plus and Prime flats do not carry it.
Both affect what you take home from a sale. Our guide to selling an HDB flat walks through the full set of costs.
The MOP and Seller’s Stamp Duty
Seller’s Stamp Duty (SSD) applies to HDB flats too. For residential property bought on or after 4 July 2025, IRAS charges it on sales within four years. Because the MOP is at least five years, an open-market sale after the MOP normally falls outside the SSD window. Our Seller’s Stamp Duty guide has the rates.
What To Do Next
- Check your exact MOP date on HDB’s My Flat Dashboard before you speak to buyers or sign for another property.
- Work out the dates with our MOP and SSD date calculator, then plan the sale with the HDB resale timeline planner.
- If you plan to buy private property after the MOP, read HDB’s private-property page first and ask your conveyancing lawyer to confirm the dates.
- If your circumstances change sharply during the MOP, write to HDB to ask about your options rather than moving out.
