Subdivided Unit Tenancy Agreement (Hong Kong)

Subdivided Unit Tenancy Agreement in Hong Kong is a residential tenancy agreement for premises that have been partitioned into smaller independent living spaces within a single flat or floor, governed by the Landlord and Tenant (Consolidation) Ordinance (Cap. 7) and the enhanced SDU protections introduced by the Hong Kong Government in 2024. Subdivided units represent a critical segment of Hong Kong's private residential rental market, housing an estimated 220,000 or more residents across the city's urban districts.

Subdivided units are formed by installing partition walls within existing flats — typically in older tenement buildings and pre-war or post-war walk-up buildings in Sham Shui Po, To Kwa Wan, Kwun Tong, Kowloon City, Wan Chai, and other high-density urban districts on Hong Kong Island and in Kowloon. Each subdivided unit is typically a self-contained living space with its own entrance, though bathroom and kitchen facilities may be shared in some configurations. SDUs vary enormously in size — from as small as 50 square feet to units of 200 square feet or more.

The Landlord and Tenant (Consolidation) Ordinance (Cap. 7), administered by the Lands Tribunal, provides the primary statutory framework for all residential tenancies in Hong Kong, including SDU tenancies. Cap. 7 was significantly amended to introduce enhanced SDU-specific protections following years of advocacy by tenant groups and housing researchers who documented the precarious legal position of SDU tenants — a population disproportionately composed of low-income families, elderly individuals, new immigrants, and ethnic minorities.

The 2024 SDU protections introduced under amended Cap. 7 establish mandatory requirements for SDU tenancies: the landlord must provide a written tenancy agreement in a prescribed form; the security deposit is capped at a maximum of two months' rent; rent increases upon renewal are subject to a cap linked to the Rating and Valuation Department's rental index for the relevant district; charging of key money (premium fees) or other irregular fees is prohibited; and the landlord must disclose their identity and the property ownership details to the tenant.

The Stamp Duty Ordinance (Cap. 117), administered by the Inland Revenue Department (IRD), requires every SDU tenancy agreement to be submitted for stamping within 30 days of execution. The stamp duty for residential tenancies is calculated at 0.25% of the total rent for terms of one year or less, 0.5% of the average annual rent for terms between one and three years, and 1% of the average annual rent for terms exceeding three years. An unstamped SDU tenancy agreement is inadmissible as evidence in any civil proceedings, limiting both landlord and tenant in the event of a dispute before the Lands Tribunal.

The Buildings Ordinance (Cap. 123), administered by the Buildings Department, governs the legality of the physical subdivision of premises. Many SDUs involve unauthorized building works (UBWs) — partition walls installed without Buildings Department approval. The Buildings Department has enforcement powers to require removal of UBWs, and SDUs in buildings subject to enforcement action may be rendered uninhabitable. Tenants should be aware that their SDU may contain UBWs, and the landlord's obligation to disclose the property's status includes information relevant to building safety.

Section 6 of the Stamp Duty Ordinance (Cap. 117) imposes the stamping obligation on SDU tenancy agreements within 30 days of execution. Section 119 of Cap. 7 confers jurisdiction on the Lands Tribunal over tenancy disputes. Section 55 of Cap. 7 empowers the Lands Tribunal to grant relief against forfeiture. Section 40 of the Buildings Ordinance (Cap. 123) makes it an offence to carry out building works — including partition wall installation — without Buildings Department approval, which is the basis on which many SDU subdivisions are classified as unauthorized building works.

An SDU Tenancy Agreement in Hong Kong is needed whenever a landlord lets a subdivided unit — a partitioned room or self-contained space within a larger flat — to a residential tenant. Following the 2024 SDU reforms under the Landlord and Tenant (Consolidation) Ordinance (Cap. 7), a written tenancy agreement is mandatory for SDU lettings — not merely established procedures — making this document a legal requirement for SDU landlords.

Landlords letting subdivided rooms in older residential buildings throughout Sham Shui Po, Kwun Tong, To Kwa Wan, Kowloon City, Mong Kok, Wan Chai, and other districts where SDUs are concentrated must provide every tenant with a written SDU tenancy agreement in the prescribed form. Failure to provide a written agreement is a breach of the SDU regulations and may expose the landlord to regulatory action.

Tenants entering into SDU arrangements in Hong Kong should insist on a written tenancy agreement before paying any deposit or rent. A written agreement that complies with the 2024 SDU protections confirms the deposit cap (maximum two months' rent), documents the agreed rent, protects against prohibited charges such as key money, and provides a formal record of the tenancy terms that can be relied on before the Lands Tribunal in any dispute.

Stamp duty compliance requires a written SDU tenancy agreement. Every SDU tenancy must be stamped by the Inland Revenue Department (IRD) within 30 days of execution under the Stamp Duty Ordinance (Cap. 117). The written agreement is the instrument that is presented to the IRD for stamping — without a written agreement, there is nothing to stamp and the parties cannot comply with Cap. 117.

Rent increase disputes require a written agreement to determine the applicable rent increase cap under the 2024 SDU protections. The cap is calculated by reference to the Rating and Valuation Department's rental index for the relevant district — the written agreement establishes the base rent from which any permitted increase is calculated.

Deposit return disputes are among the most common SDU tenancy disputes in Hong Kong. A written agreement specifying the deposit amount (confirmed to be within the two-month cap), the conditions for deduction, and the return timeline provides the evidentiary basis for a Lands Tribunal claim if the landlord wrongfully withholds the deposit.

A Subdivided Unit Tenancy Agreement in Hong Kong must include specific elements required by the Landlord and Tenant (Consolidation) Ordinance (Cap. 7) as amended by the 2024 SDU protections, and must comply with the Stamp Duty Ordinance (Cap. 117) to be enforceable before the Lands Tribunal. Each element serves a distinct protective function for either the landlord or the tenant.

Party identification requires the landlord's full legal name, Hong Kong Identity Card (HKID) number or company name and Companies Registry number, and contact address. The tenant's full legal name and HKID number must also be recorded. Under the 2024 SDU protections, the landlord must disclose their identity — including proof of ownership or authority to let the premises — to the tenant before or at the time of signing the tenancy agreement.

Premises description must identify the SDU precisely: the full address of the building, the floor, the flat number, and the specific subdivided unit within the flat (e.g. Room A, Room B, or Unit 1). Where the building's lot number and Deed of Mutual Covenant (DMC) reference are available, these should be included. The description should note whether the SDU has exclusive use of bathroom and kitchen facilities or shares these with other occupants.

Term specifies the start date and end date of the tenancy. SDU tenancies are typically for a fixed term of one or two years. The agreement should specify what happens at the end of the fixed term — whether the tenancy converts to a periodic tenancy, whether there is a renewal option, and the notice required to terminate a periodic tenancy.

Rent states the monthly rent in Hong Kong Dollars (HKD), the payment date (typically the first day of each calendar month), and the acceptable payment methods. For SDU tenancies, rent receipts are important evidence — the agreement should require the landlord to provide written receipts for all rent payments.

Security deposit confirms that the deposit amount does not exceed two months' rent — the maximum permitted under the 2024 SDU protections. Any deposit exceeding this cap is prohibited. The agreement should specify the conditions under which the landlord may make deductions from the deposit (rent arrears, damage beyond fair wear and tear), and the timeline for returning the deposit after the tenancy ends.

SDU tenant rights statement confirms the tenant's entitlement to the protections introduced under the 2024 SDU reforms: the deposit cap, the rent increase cap upon renewal, the prohibition on key money and irregular charges, and the tenant's right to a written agreement. Under the Landlord and Tenant (Consolidation) Ordinance (Cap. 7), SDU tenants who have been overcharged deposits or subjected to prohibited fees may seek recovery of the excess amounts.

Rent increase cap upon renewal specifies the applicable cap on rent increases when the SDU tenancy is renewed. The cap is linked to the Rating and Valuation Department's rental index for the relevant district — an objective measure that prevents landlords from imposing arbitrary rent increases on renewal. The specific cap percentage applicable at the time of renewal is determined by reference to the Rating and Valuation Department's published index.

Prohibited charges clause confirms that no key money, premium, goodwill payment, or other irregular charges have been or will be demanded from the tenant in connection with the tenancy. Any such charges are prohibited under the 2024 SDU protections and may be recovered by the tenant.

Utilities allocation specifies how electricity, water, gas, and broadband costs are divided between the tenant and the landlord (or among multiple SDU occupants in the same flat). Meter readings at commencement and expiry of the tenancy should be recorded.

Stamp duty clause confirms that the tenancy agreement will be stamped by the Inland Revenue Department (IRD) within 30 days of execution under the Stamp Duty Ordinance (Cap. 117), and identifies which party bears the stamp duty cost.
