Rates and thresholds change. The current figures are kept in one place: the Singapore property rules reference.
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. For the full breakdown, including the approval process, nationality caps, and penalties, see the complete guide to HDB subletting rules.
Can I rent out a room in my HDB flat before 5 years?
Yes. You can rent out a bedroom without waiting for the 5 year MOP, because HDB's bedroom rules do not list an MOP requirement. The conditions for HDB subletting are different for a room and for the whole unit.
- Renting out a room: own a 3 room or bigger flat, keep living in it, and get HDB approval before the tenancy starts, through MyHDB at $9 per bedroom.
- Renting out the whole unit: the owner must be a Singapore Citizen who has completed the MOP, which is 5 years for most flats, and HDB approval is also needed before the tenancy starts. Plus and Prime flats cannot be rented out whole, even after the MOP.
Room subletting vs whole flat subletting
| Criterion | Room subletting | Whole flat subletting |
|---|---|---|
| HDB approval needed | Yes, before the tenancy starts, and the owner must keep living in the flat | Yes, before the tenancy starts |
| Who can rent out | Singapore Citizen or PR owner of a 3 room or bigger flat (1 and 2 room owners cannot rent out bedrooms) | Singapore Citizen owner only (PR owners cannot) |
| MOP required | HDB's bedroom rules do not list an MOP requirement | Yes, 5 years for most flats. Prime and Plus flats cannot be rented out whole even after the 10 year MOP |
Occupancy and nationality caps
HDB's occupancy cap counts owners, authorised occupiers and tenants together. For bedroom rental the cap is 6 for a 3 room flat and 8 for a 4 room or bigger flat, and the 8 applies until 31 Dec 2028, after which it reverts to 6. For whole flat rental the tenant cap is 4 for 1 and 2 room flats, 6 for 3 room flats and 8 for 4 room and bigger flats (also reverting to 6 after 31 Dec 2028), and it does not apply if all the tenants are one family unit. Non citizen quota: when a whole flat is let to a tenant who is a non Malaysian non citizen, HDB applies a quota of 8% at neighbourhood level and 11% at block level. Malaysians are exempt, and the quota does not apply to bedroom rental. Each tenancy runs a minimum of 6 months and a maximum of 3 years (2 years if any tenant is a non Malaysian non citizen).

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 renting out without HDB approval, 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.
