The HDB Minimum Occupation Period (MOP) is the time HDB flat owners must physically occupy their flat before they can sell on the open market, rent out the whole flat, or buy a private property. The standard MOP is 5 years for most flat types. Plus and Prime flats have a 10-year MOP under rules introduced in 2024.
MOP rules by flat type as of 2026
| Flat type | MOP | Notes |
|---|---|---|
| Standard BTO / SBF / OBF | 5 years | From key collection |
| Plus flats (introduced Aug 2024) | 10 years | Plus restrictions on resale price |
| Prime flats | 10 years | Plus subsidy clawback on resale |
| Resale HDB (newly purchased) | 5 years | From completion date |
| EC (Executive Condominium) | 5 years (sale to SC/PR only) | 10 years after May 2026 EC rules for new tenders |
MOP is enforced through HDB's flat ownership registration. Source: HDB MOP framework.
What MOP affects
- Resale on open market: Cannot sell until MOP completes.
- Whole-flat rental: Cannot rent out the entire flat to non-occupier tenants during MOP.
- Buying private property: Cannot buy a private condo or landed property during MOP.
- Room rental: Allowed during MOP if the owner continues occupying the flat.
Exceptions to MOP
HDB grants MOP waivers in specific hardship cases:
- Divorce: One ex-spouse can sell or take over the flat.
- Death of co-owner: Surviving owner can sell or transfer.
- Bankruptcy: HDB may approve sale to satisfy creditors.
- Repossession: HDB takes ownership back; sells via SBF.
Standard hardship waivers do not include voluntary moves for work or family circumstances.
Worked example: Plus flat resale at year 10
| Year | Permitted action |
|---|---|
| 0 (key collection) | Move in and occupy |
| 1–9 | Occupy only; no resale, no whole-flat rental |
| 10 | MOP completes — resale on open market permitted |
| 10+ | Plus subsidy clawback applies on resale; buyer also must be SC family |

Frequently asked questions
Does MOP run from booking or key collection?
From key collection (TOP for new flats; completion date for resale). Booking date is not the start.
Can I rent out the whole flat to my parents during MOP?
Whole-flat rental during MOP is prohibited even to family members. Room rental is allowed if you continue occupying.
What happens if I move out during MOP?
You forfeit MOP credit. The clock resets if you return; otherwise sale on hardship grounds may be required.
