Yes, you must notify HDB and obtain approval to sublet your flat. You can do this by registering the subletting details, including your tenant particulars, through HDB’s website (via MyHDBPage) within 7 days of the tenancy commencement. Ensure the rental follows the maximum permitted period (up to 3 years if all tenants are Singaporeans/Malaysians, or 2 years otherwise) and meets HDB’s eligibility criteria.
