HDB MOP 2026: Rules, Penalties & Subletting Guide

The MOP is the single biggest restriction on what you can do with your HDB flat. Sell it too early, sublet it without permission, or treat it as an investment property and HDB can claw back grants and force a disposal. The rules are simpler than they look once you know how the clock runs.

Use the HDB Grant Calculator to see how MOP affects grant clawbacks if you ever need to sell early.

MOP at a glance for 2026

Flat type	MOP	Clock starts
New BTO (subsidised)	5 years	Key collection date
Resale flat (with grants / HDB loan)	5 years	Legal completion date
Resale flat (cash + bank loan, no grants)	5 years	Legal completion date
DBSS flat	5 years	Key collection date
Executive Condominium (EC)	5 years (HDB-side) + 5 more before privatisation	TOP date
Prime Location Public Housing (PLH)	10 years	Key collection date

The 5-year rule has been in place since 2010. The 10-year MOP for PLH is the new variant introduced from 2022 BTO launches in Tanjong Pagar, Queenstown and Bukit Merah.

What you can and cannot do during MOP

Allowed during MOP:

• Live in the flat (you must)
• Rent out individual rooms (subject to MOM Foreign Worker / room rental rules)
• Rent out partial rooms via short-term occupation (NOT short-term Airbnb-style — that's banned everywhere in HDB)
• Make renovations and home improvements

Not allowed during MOP:

• Sell the flat on the open market
• Rent out the whole flat
• Buy a private residential property (in Singapore or overseas)
• Decouple ownership without going through HDB's review process

How MOP starts: BTO vs resale

For BTO buyers: MOP starts on your key collection day, usually 2–4 weeks after you receive the Notice of Vacant Possession. So a couple who:

• Booked a 2022 BTO
• Got keys in March 2026 (4-year build)
• Will reach MOP on March 2031 (5 years from key collection)

That's 9 years between application and the freedom to sell.

For resale buyers: MOP starts on your legal completion date — when the flat is officially transferred to your name. You start your own 5-year clock. So if you buy a resale flat in May 2026, you can next sell it in May 2031.

Important: Your MOP is independent of the seller's MOP. Even if the previous owner had been in the flat for 30 years, you must still serve your full 5 years.

Subletting rules during and after MOP

During MOP — only individual rooms (one or more) can be rented, while the owner continues to occupy the unit.

After MOP — the whole unit can be rented out, subject to:

• HDB approval for rental period (renewable up to 3 years per cycle)
• Maximum 6 occupiers in the flat (4 if 1- or 2-room)
• Tenants cannot be tourists or social-visit-pass holders
• Owners cannot live overseas indefinitely while subletting

Penalties for unauthorised subletting can include compulsory acquisition of the flat at HDB's option.

The buy-private rule during MOP

You cannot own private residential property — Singapore or overseas — during your HDB MOP. If you inherit a property mid-MOP, you must dispose of either the inherited property or the HDB flat within 6 months.

After MOP, you can buy private property and keep your HDB. But:

• ABSD applies (20% for SC second property)
• You must continue living in the HDB or sublet it with HDB approval

Selling before MOP — when is it possible?

The only routes to dispose of a flat before MOP:

1. HDB compulsory acquisition — rare, only for SERS or CIP redevelopment
2. Divorce settlement — case-by-case, with court order
3. Financial hardship — HDB will assess; you may be required to sell back to HDB at a discounted price
4. Death of an owner — inheritance-related disposal
5. HDB special compassionate cases — medical, family hardship

Going around the rules — e.g. selling under a nominee arrangement — is a criminal offence under the Housing & Development Act. Penalties include compulsory acquisition and a 5-year ban from buying any HDB flat.

Grant clawback if you sell early

If you used grants and need to sell within the MOP via an HDB-approved exception, the grants are clawed back with interest:

• CPF Housing Grant (CHG): full clawback
• Enhanced Housing Grant (EHG): full clawback
• Proximity Housing Grant: full clawback
• The clawback amount is taken from your CPF + sale proceeds

Plus you owe the resale levy if you bought a second subsidised flat — though this only applies if you're moving from one subsidised flat to another.

Common MOP mistakes

• Counting from the application date. No — it's key collection. Add the BTO build time.
• Decoupling and forgetting MOP applies to the new co-owner profile. A spouse buying out the other's share doesn't reset MOP, but the buying spouse must still meet eligibility.
• Renting out the whole flat to family while overseas. Counts as subletting; needs HDB approval and breaks MOP if undisclosed.
• Buying private property during MOP "in your spouse's name only". HDB treats spousal property as joint family ownership; this is a violation.
