1. What is the HDB MOP?
The Minimum Occupation Period (MOP) is the duration during which the registered owners of an HDB flat must physically occupy the unit before HDB permits its sale on the open market or its rental as a whole flat. The policy underpins HDB's owner-occupier framework — public housing in Singapore is intended for homes, not flips.
The MOP is counted from a specific start date (usually key collection) and continues without interruption. Periods when none of the owners physically resides in the flat may not count towards MOP. Owners going overseas long-term should inform HDB.
2. MOP by flat type
| Flat type | MOP | Subsidy clawback on resale? |
|---|---|---|
| Standard BTO | 5 years | No |
| Plus BTO (from Oct 2024) | 10 years | Yes — % of resale price returned to HDB |
| Prime BTO (from 2021) | 10 years | Yes — higher % + 30-month PR wait-out for resale buyers |
| HDB Resale (with CPF Grants) | 5 years | No (grants may be recovered for early exit) |
| DBSS | 5 years | No |
| Executive Condominium | 5 years (privatised after 10) | Resale levy applies on subsequent subsidised purchase |
See Plus vs Prime vs Standard BTO for the differences between the three new BTO models.
3. When MOP starts and ends
For BTO, DBSS, and EC: MOP starts on the date of key collection. For HDB resale flats bought with CPF Housing Grants: MOP starts on the legal completion date (Sub-Lease Effective date).
MOP runs in calendar years from the start date. A flat with a 5-year MOP that took key collection on 15 March 2023 reaches MOP on 15 March 2028. HDB will not approve a resale before that date except under the listed exceptional circumstances.

4. What's allowed during MOP
- Live in the flat as owner-occupier — at least one registered owner must reside in the unit.
- Rent out individual rooms — subject to HDB approval and a maximum number of bedrooms permitted for rental based on flat type. Owners must still live in the flat.
- Do minor renovations — within HDB's permitted scope. Structural changes need separate approval.
During MOP you CANNOT:
- Sell the flat on the open market.
- Rent out the entire flat to anyone.
- Buy a private residential property (in Singapore or overseas) while still owning the HDB.
- Be the registered owner of any other residential property concurrently.
5. What changes after MOP
- Open-market sale — you can sell to any eligible buyer; HDB still vets the resale transaction.
- Whole-flat rental — permissible subject to HDB approval and the non-Malaysian foreigner quota where applicable.
- Buy private property — you may buy a private property while still owning the HDB.
- Plus / Prime subsidy clawback applies — a percentage of the resale price is returned to HDB (the exact rate is announced at launch and recorded in the lease).
- EC privatisation — at the 10-year mark, an EC is fully privatised and can be sold to foreigners.
6. Early sale exceptions
HDB may, at its discretion, allow a sale before MOP in narrow circumstances:
- Death of an owner.
- Divorce or annulment of marriage.
- Severe financial hardship (e.g. medical, unemployment).
- Permanent emigration overseas.
- Other exceptional circumstances on a case-by-case basis.
Approval is not automatic. CPF grants received may need to be refunded. Owners apply directly to HDB with supporting documents.
