How long is the HDB MOP?

It depends on the flat: 5 years of actual occupation for Standard (and older unclassified) flats, DBSS flats and most SERS replacement flats; 10 years for Plus and Prime flats, including resale ones; and 20 years for a Fresh Start Housing Scheme flat. The MOP starts when the purchase is legally completed, which for a new flat is key collection, and periods you do not live in the flat do not count (HDB, Eligibility for Selling a Flat, checked 1 Oct 2026).

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 the MOP. You may rent out bedrooms in a 3-room or bigger flat while you continue living there, with HDB's approval before the tenancy starts: one bedroom in a 3-room flat, two in a 4-room or bigger flat (HDB, Renting Out Bedrooms, checked 1 Oct 2026). The exception is a 3Gen flat: no bedrooms may be rented out within its MOP (HDB, Conditions After Buying a New Flat, read 3 Oct 2026).

Can I keep my HDB flat if I buy private property after the MOP?

It depends on the owners' citizenship. Where at least one owner is a Singapore Citizen, the household may buy private residential property once the MOP is fulfilled and retain the flat. Where all the owners are Singapore Permanent Residents, they must tell HDB before anyone listed exercises the Option to Purchase, and sell the flat within 6 months of acquiring local private residential property (HDB, Acquiring Private Property, updated 24 Jul 2026). Either way the MOP must be served first. That bar covers private homes in Singapore and overseas, includes exercising an Option during the MOP, and binds the occupiers listed in the flat application as well as the owners.

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.

HDB MOP: How Long Is the Minimum Occupation Period (5 Years)

Practise this section (156 questions) → · 4.4 Sale of HDB flats, in sets of about 30

Must-know for the exam

MOP by flat: 5 years Standard, DBSS and newer SERS flats; 10 years Plus and Prime; 20 years for a Fresh Start Housing Scheme flat.
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 bedrooms with HDB approval before the tenancy.
After the MOP a household with an SC owner may buy private property and keep the flat; an all-SPR household must sell within 6 months of acquiring local private property.
The bar on buying private property during the MOP binds every core member (essential occupier) in the flat application, who must also live in the flat throughout the MOP.
Fresh Start: rental families aged 35 to below 55, with an SC child under 21, buy a 2-room Flexi or 3-room flat on a 45- to 65-year lease.
During the MOP no one listed may acquire private residential property in Singapore or overseas; even exercising an OTP for one is a breach.

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, starting from the day the flat purchase is legally completed: key collection for a new flat, resale completion for a flat bought on the open market (HDB, Eligibility for Selling a Flat, checked 1 Oct 2026).
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.

How the flat was bought	MOP
From HDB, or on resale: Standard or unclassified flat	5 years
From HDB, or on resale: Plus or Prime flat (including PLH flats sold before Oct 2024)	10 years
DBSS flat bought from the developer	5 years
SERS replacement flat, site announced on or after 7 Apr 2022	5 years from key collection
SERS replacement flat at the designated site, announced before 7 Apr 2022	The earlier of 7 years from selection or 5 years from key collection
Fresh Start Housing Scheme flat	20 years

MOP by type of flat (HDB, Eligibility for Selling a Flat, checked 1 Oct 2026).

Core members stay put. The applicants and occupiers who made the household eligible must remain in the flat application and physically live in the flat throughout the MOP; their names cannot be removed to free someone up (HDB, Couples and Families page, updated 23 Aug 2026).

What you can and can't do

Action	During MOP	After MOP
Sell on the open market	No	Yes
Rent out the whole flat	No	Yes, Singapore Citizen owners only, with HDB approval; never for Plus or Prime flats
Rent out spare bedrooms (3-room or bigger)	Yes, with HDB approval before the tenancy starts, while you live there. Not in a 3Gen flat	Yes, same approval
Buy private residential property	No	Yes — but an all-SPR household must sell the flat within 6 months of buying local private property

▸ More checkpoints: why the MOP keeps Seller's Stamp Duty off HDB sales

There is no blanket HDB exemption from Seller's Stamp Duty (IRAS exempts only specific cases, such as a flat returned to HDB under SERS or on repossession) — a flat is residential property and is within SSD's scope. What keeps SSD off almost every flat sale is arithmetic. The SSD holding period is 4 years for residential property acquired on or after 4 Jul 2025 (3 years for property acquired before that date — IRAS), while the MOP is 5 years of actual occupation. By the time an owner may lawfully sell on the open market, the SSD window has already closed.

Answer "MOP", not "exempt". A client who says "it's HDB, so there's no SSD" reaches the right outcome for the wrong reason — and the reasoning is what a Section B answer is marked on.
Where the clock starts. SSD runs from the date of acquisition. For an inherited flat IRAS counts from the date the deceased acquired it, not the date of death, so inheriting does not restart the clock (IRAS, Seller's Stamp Duty, read 1 Oct 2026). The stamp-duties concept sets out the rates and IRAS's exemptions.

How long is the MOP for Standard, Plus or Prime, and Fresh Start flats?Show answer
5 years for Standard or unclassified, 10 years for Plus and Prime (resale buyers too), and 20 years for a Fresh Start flat. It counts years actually lived in, not elapsed time.
A buyer purchases a resale flat whose seller has already met the MOP. Does the buyer face an MOP?Show answer
Yes, a fresh 5-year MOP from resale completion (10 years for Plus or Prime). The seller's MOP does not transfer, and it makes no difference whether a CPF grant or HDB loan was taken.
A BTO flat with a 5-year MOP: keys Jan 2020, lived in one year, vacant two years, reoccupied Jan 2023. When is the MOP met?Show answer
Around Jan 2027. MOP counts only years the owners actually live in the flat, so the two vacant years do not count: 1 year (2020) plus 4 more from Jan 2023 makes 5.
After the MOP, can an all-SPR household buy a condo and keep its HDB flat?Show answer
No. It must notify HDB before the OTP is exercised and sell the flat within 6 months of acquiring local private residential property. A household with at least one SC owner may keep the flat.
During the MOP, may an owner rent out the whole flat or spare bedrooms?Show answer
Bedrooms only, in a 3-room or bigger flat, with HDB approval before the tenancy starts, while living there; not in a 3Gen flat. Whole-flat renting is barred during the MOP.

Common questions

How long is the HDB MOP?: It depends on the flat: 5 years of actual occupation for Standard (and older unclassified) flats, DBSS flats and most SERS replacement flats; 10 years for Plus and Prime flats, including resale ones; and 20 years for a Fresh Start Housing Scheme flat.
