Paper 2 · HDB Policies
HDB MOP: How Long Is the Minimum Occupation Period (5 Years)
Must-know for the exam
- The MOP gates when an HDB owner can sell the flat, rent out the whole flat, or buy private residential property.
- The MOP is generally 5 years of actual occupation from key collection (new flat) or resale completion (open-market flat), never from the purchase or booking date.
- Periods the flat is not physically occupied (vacant, whole-flat sublet, owner overseas) do not count and push the MOP completion date later.
- A resale flat carries its own fresh 5-year MOP for the buyer, whether or not a CPF housing grant or HDB loan was taken; the seller's MOP does not transfer.
- PLH flats and all Plus and Prime flats carry a 10-year MOP that binds resale buyers too, and Plus/Prime owners may never rent out the whole flat, even after MOP.
- During the MOP the owner cannot sell on the open market, rent out the whole flat, or buy private property, but may rent out spare rooms while living there.
- After the MOP a Singapore Citizen owner may buy private property and keep the flat; an SPR owner must sell within 6 months of buying private property, Singapore or overseas.
The Minimum Occupation Period (MOP) gates when an HDB owner can sell, rent out the whole flat, or buy private property. It is one of the most-tested HDB rules — and the trap is how the period is counted.
How it's counted
- MOP is generally 5 years of actual occupation, counted from key collection for a new flat, and from the date of resale completion for a flat bought on the open market.
- A resale flat carries its own fresh MOP. The seller having served theirs does not transfer — the buyer starts a new 5-year clock, whether or not they took a CPF housing grant or an HDB loan. "The flat has already MOP-ed" is a statement about the seller, never about the buyer.
- Periods you do not physically occupy the flat (left vacant, whole-flat sublet, overseas) do not count and can push the MOP date back.
- Prime Location (PLH) flats, and all Plus and Prime flats under HDB's classification framework, carry a 10-year MOP, not 5 — and that 10-year MOP binds a resale buyer of such a flat too.

Common questions
- How long is the HDB MOP?
- For most flats the MOP is 5 years of actual occupation from key collection. Certain schemes can differ, so the specific flat's conditions should always be checked.
- Does a resale HDB flat have an MOP?
- Yes. Buying on the open market starts a fresh 5-year MOP of your own, counted from the date of resale completion — the seller's completed MOP does not carry over, and it makes no difference whether you took a CPF housing grant or an HDB loan. Buy a Plus or Prime flat on the resale market and the MOP you inherit is 10 years. Confirm your flat's exact MOP with HDB.
- Can I rent out my HDB flat during the MOP?
- You cannot rent out the whole flat during MOP, but you may rent out spare bedrooms (subject to HDB's rules) while you continue living there.
- Can I keep my HDB flat if I buy private property after the MOP?
- It depends on your citizenship. A Singapore Citizen flat owner may buy private residential property once the MOP is fulfilled and retain the flat. A Singapore Permanent Resident flat owner may not — HDB requires SPR flat owners to sell the flat within 6 months of buying private residential property, whether that property is in Singapore or overseas. Either way the MOP must be served first, and that restriction binds essential occupiers listed in the flat application as well as the owners. Confirm the current position with HDB.
- Can I sell my HDB flat before the MOP is up?
- Not as of right. Before the MOP is fulfilled you cannot sell on the open market unless HDB permits it — you would have to appeal, and HDB decides case by case on the circumstances (divorce, bankruptcy and loss of citizenship are the situations usually cited). If no open-market sale is allowed, the remaining option is to surrender the flat to HDB at the compensation price HDB determines, which is generally below the open-market resale price. Confirm the current position with HDB.
