Subletting Regulations

Flat owners’ responsibilities

As a flat owner subletting your flat, you must ensure that:

  • Only the authorised subtenants are staying in the flat
  • The number of subtenants does not exceed the maximum number allowed
  • Your subtenants do not further sublet the flat to others, create nuisance or misuse the flat
  • Your subtenants are legally residing in Singapore
  • Your subtenants comply with all the covenants in the lease and the provisions of the Housing & Development Act. You are responsible for all infringements (if any) committed by them

The property tax will be revised when you sublet your flat. You can get more information from the Inland Revenue Authority of Singapore (IRAS), through their website

If your subtenants request for proof that they are registered with HDB, you may print a confirmation letter showing the names of all authorised subtenants listed in the flat, after log-in with your Sing Pass at, via Subletting of Whole Flat > Enquiry on Subtenants. Alternatively, you may use our ‘Enquiry on Authorised Subtenants’ e-Service to assure your subtenants that they have been registered with HDB.

Subletting period

The minimum subletting period for each subtenant must be 6 months per application. You are not allowed to sublet your flat or bedroom on a short-term basis as it may disrupt the living environment and pose security concerns for our residents.

The subletting period is indicated in the approval letter, up to a maximum of 3 years if all the subtenants are Singaporeans or Malaysians. The maximum is capped at 1.5 years for non-Malaysian non-citizen subtenants. Non-citizens refer to Singapore Permanent Residents and foreigners. You are required to reapply for approval each time you sublet your flat or renew the subletting application.

Unauthorised subletting of flat

Our flats are meant for homeowners to live in. The terms and conditions for subletting help ensure a conducive and harmonious living environment in HDB estates. Singaporean citizens have to meet all the eligibility conditions and obtain our written approval by submitting an online application.

We take a very serious view of unauthorised subletting and will not hesitate to take action against those who flout the rules. We can impose a financial penalty or acquire the flat. Even if you have obtained approval to sublet your flat, you should conduct regular checks to ensure that the rules and regulations are met.


We conduct regular checks to take enforcement action against unauthorised subletting. We also carry out targeted investigations on suspected cases of unauthorised subletting when we get feedback from the public. From January 2013 to December 2014, we carried out more than 13,000 flat inspections and took action against 24 flat owners for unauthorised subletting.

You can report any suspected unauthorised subletting and misuse of flats at 1800-555-6370. The hotline is available from Monday to Friday, 8am to 5pm. All information provided will remain confidential.
