Owning the flat does not mean you can rent it out however you like. HDB layers different rules on room subletting versus whole flat subletting, and the penalties for getting it wrong are severe.
Room subletting vs whole flat subletting
| Criterion | Room subletting | Whole flat subletting |
|---|---|---|
| HDB approval needed | No, if owner still lives there | Yes, explicit approval required |
| MOP required | Yes, 5 years | Yes, 5 years |
Occupancy and nationality caps
Maximum occupancy is 6 persons for 3 room flats and 8 persons for 4 room and larger flats, family and tenants combined. Non Malaysian foreign tenants are subject to nationality quotas: 4 room and larger flats may house up to 4 non Malaysian foreigners, 3 room flats up to 2.
Tax and enforcement
Rental income is taxable under Section 10(1)(f) of the Income Tax Act, with legitimate deductions available. Illegal subletting, Airbnb style short term stays, exceeding occupancy caps, or failing to register tenants, can result in HDB exercising compulsory acquisition of the flat, a severe and real penalty.
What net yield actually looks like
After MOP, typical net yield for a 4 room flat runs 3.0 to 3.5% after tax and costs, closer to 2.8% in Queenstown and Bishan due to higher valuations.
Frequently asked questions
Do I need HDB approval to rent out a spare room?
No, not if you continue living in the flat yourself and you have completed your 5 year MOP. Subletting the whole flat is different, that always needs explicit HDB approval.
Can I list my HDB flat on Airbnb?
No. Short term subletting, Airbnb style stays, is illegal for HDB flats under any circumstances, regardless of MOP status or approval.
Thinking about subletting your HDB flat or a room?
Winfred checks your MOP status, the applicable caps, and the real net yield before you advertise anything.
