Many Singaporeans are exploring new ways to supplement their earnings, and one popular option is renting out HDB room/s. For flat owners with extra bedroom/s, this provides a steady side income while making full use of the flat. However, the renting out of HDB bedrooms comes with specific rules and requirements that owners must follow. Understanding the application process, eligibility criteria, and tenant regulations ensures that you can rent out your room smoothly and in compliance with HDB guidelines.

Renting out HDB room can be an excellent side income opportunity for flat owners in Singapore. In contrast to renting out an entire flat, renting out rooms in a 3-room or larger HDB flat is allowed even before the minimum occupation period is fulfilled, and includes a relatively straightforward application process through HDB’s e-services. With careful tenant screening, compliance with the minimum occupation period, maximum number of tenants, and quota rules, owners can rent out your spare bedroom to generate more income while still living in the flat. This blog outlines the key steps in the application process and legal obligations for flat owners wanting to rent out your HDB rooms for side income.
Only flat owners of 3-room or larger HDB flats are permitted to rent out rooms. Unlike renting out the whole flat, this applies even if you have not yet met the minimum occupation period. Both Singapore Citizens and Singapore Permanent Residents, including flat owners of Plus or Prime flats, are allowed to rent out rooms. However, the maximum number of tenants depends on flat size, and there are quota restrictions for non-citizens. It is essential that the owner resides in the flat with the tenants throughout the tenancy.
Renting out your HDB room is not just about finding a tenant. Flat owners must follow specific procedures set out by HDB to ensure the renting out of bedrooms is legal and properly recorded. The process involves confirming eligibility, applying for approval, observing rules on tenancy, and ensuring tenants meet the required criteria. Below is a clear step-by-step guide to help you rent out your flat room smoothly and with confidence.
First, check that your flat is a 3-room or larger HDB flat, as only such bedrooms can be rented out. Ensure you are the flat owner, whether you're a Singapore Citizen or SPR, and note that you may rent out your rooms even if the minimum occupation period is not completed.
You must seek HDB’s approval before renting out bedrooms. Apply via HDB’s online e-services. The application fee is $10 per bedroom, and the outcome is communicated immediately. Once you have approval, ensure to notify HDB of any changes, such as tenancy termination or tenant details, within seven days.
Check the Non-Citizen Quota if your prospective tenants include Singapore Permanent Residents or foreigners, excluding Malaysians. The quota is capped at 8 per cent at the neighbourhood level and 11 per cent at the block level, and it does not apply to renting out bedrooms. Use HDB’s e-services to verify if you can rent out your flat or rooms to non-citizen tenants.
Each tenancy must be at least six months long, as short-term lets are not allowed. The maximum renting-out period per application is three years. However, if one or more tenants are non-Malaysian, non-citizens such as an SPR or foreigner, the maximum period is two years.
Ensure your tenants are eligible. They can be Singapore Citizens, SPRs, or non-citizens holding valid passes such as Employment Pass, S Pass, Student Pass, Dependant Pass, or Long-Term Social Visit Pass with at least six months validity. You must also verify their status via ICA or MOM as needed.
Advertise your flat and highlight that you can rent out your rooms. Once you find prospective tenants, screen them thoroughly and finalise a tenancy agreement aligned with HDB rules, as this forms part of the application process. Once the agreement is in place and you have HDB’s approval, tenants may move in. Be sure to remain living in the flat for the duration of the renting out of bedrooms. Monitor the number of tenants, as total occupancy, including yourself and any authorised occupiers, must not exceed the limit based on your flat type. For example, six persons for a 3-room flat, while four-room and larger flats are allowed up to eight occupants until 31 December 2026 under temporary relaxation.
When you rent out your HDB room, you take on the responsibilities of a landlord. Beyond the potential side income, there are rules to follow that protect both flat owners and tenants. These responsibilities are crucial for ensuring that the renting out of the flat is legal and sustainable.
One key requirement is that the owner must continue living in the flat. Bedrooms can be rented out, but the entire flat cannot be vacated unless you have approval to rent out the whole unit after meeting the minimum occupation period. This ensures that your flat remains a proper home rather than a commercial lodging house.
Whenever there is a change in tenants, such as early termination, new occupants, or a renewal of the tenancy, HDB must be informed within seven days. This keeps the housing records accurate and protects you as the owner should disputes arise. Failure to update tenancy details can result in penalties or the withdrawal of your approval to rent out.
The maximum number of tenants who can rent out rooms in the flat depends on its size. For instance, a 3-room flat can host up to six people in total, while larger flats may allow more. These limits include the owner, authorised occupiers, and all tenants. Overcrowding is strictly prohibited, and landlords must ensure that their rental arrangements comply with the stated number of tenants permitted by HDB.
While the process to rent out your room may appear simple, flat owners often face common issues that could lead to fines or cancellation of approval. Avoiding these pitfalls ensures that renting out your flat remains a reliable source of side income.
Some owners attempt to partition a bedroom into smaller units to increase the number of tenants they can rent out to. This is not allowed, as HDB does not permit structural alterations that compromise the safety or liveability of the flat. Illegal redesigns can result in enforcement action and the requirement to reinstate the original layout at your cost.
Exceeding the maximum number of tenants is a frequent violation. While it may be tempting to squeeze in more tenants for extra income, the renting out of HDB flats is strictly regulated. Overcrowding creates discomfort for residents, breaches housing rules, and can lead to serious penalties for the owner.
Flat owners must verify that each tenant has valid passes or is legally allowed to stay in Singapore. Failing to conduct proper checks risks housing ineligible tenants, such as overstayers or individuals without the proper permits. As the owner, you are fully responsible for screening tenants, keeping copies of their identification and passes, and ensuring that their documents remain valid throughout the tenancy.
Renting out your HDB room can be a rewarding way to generate side income, provided you follow the proper regulations and meet all eligibility requirements. From ensuring the flat meets HDB’s rules, to verifying tenant documentation and respecting occupancy limits, every step plays a part in making the renting-out process smooth and secure.
