Private domestic flats on Hong Kong Island, in Kowloon and in the New Territories follow the mainstream route: written renewal, stamping within 30 days, Form CR109 within one month. The exemption from CR109 covers only a tenancy of five years or more with no early termination right and no rent increase during the term, which almost no renewal satisfies.
Subdivided units sit under a separate regime. Part IVA of Cap. 7 has applied since 22 January 2022 to a regulated tenancy of a subdivided unit let for domestic use to an individual. The cycle runs two years plus two years, the tenant is entitled to a second term, and the landlord must make the offer on statutory Form AR1 during the offer period, being the second calendar month before the month the second term starts. The increase cannot exceed the movement in the territory wide domestic rental index and is capped at 10 per cent. Form AR2 replaces Form CR109 and is due within 60 days of commencement.
Non-domestic premises, meaning offices, shops, godowns and industrial units, fall outside Part IV. No Form CR109 is required and rental particulars reach the Rating and Valuation Department on Form R1A instead. Stamp duty applies identically, and commercial renewals more often exceed three years, which pulls in the deed and registration requirements.
Home Ownership Scheme flats with the premium unpaid may only be let through the designated letting scheme, and renewing outside it risks the Housing Authority treating the letting as a breach. Public rental housing cannot be sublet at all, and a renewal covering an unauthorised rooftop structure on a New Territories village house hands the tenant possession of something the Buildings Department may order removed.
