Is Airbnb Legal in Hong Kong? The 28-Day Rule and Cap. 349 Explained

The short answer is that an Airbnb-style listing for paid stays of fewer than 28 consecutive days requires a hotel or guesthouse licence under Cap. 349 if its operation falls within the Ordinance's definition of a hotel or guesthouse and no statutory exclusion applies. A residential flat is not automatically barred from licensing; if its operation falls within Cap. 349's scope and no statutory exclusion applies, it must qualify for and obtain a licence. The criminal penalties are severe and enforcement activity has increased significantly in recent years.

If you are considering a Hong Kong investment property and factoring in short-term rental income to justify the yield, first confirm whether the proposed operation falls within Cap. 349's scope and, if it does, whether the premises can qualify for and obtain a licence.

The Legal Foundation: Cap. 349

The Hotel and Guesthouse Accommodation Ordinance (Cap. 349) requires premises operating as a hotel or guesthouse to hold a valid licence issued by the Home Affairs Department's Office of the Licensing Authority (OLA), subject to statutory exclusions.

The 28-day rule is the key threshold. Cap. 349 excludes premises only where all accommodation is offered for a minimum of 28 continuous days per letting and no fee is waived, refunded or reduced if a letting is shortened below 28 days. Stays shorter than 28 days require a licence where the premises meet the Ordinance's definition of a hotel or guesthouse.

How Residential Flats Can Qualify for a Guesthouse Licence

The Ordinance does not categorically bar residential flats from licensing. The OLA's guide says a general guesthouse licence may be issued for premises in a domestic building or the domestic part of a composite building. Applicants must meet requirements including:

• Fire safety installations: Required measures include emergency lighting and exit signs; some systems, including sprinklers, depend on the premises.
• Barrier-free access: Premises must meet applicable barrier-free access requirements; necessary work depends on approved plans and the individual premises.
• Structural safety: An Authorised Person or Registered Structural Engineer may need to submit structural justification for proposed guesthouse use or works affecting the building.
• Means of escape: Internal corridors and exit routes must meet the OLA's specified escape-route requirements.

The OLA's guide covers guesthouses in domestic parts of existing buildings approved by the Building Authority, and requires applicable building and fire-safety compliance, including structural justification for a proposed change from domestic to guesthouse use.

Individual flats in residential buildings may qualify for a general guesthouse licence if the premises and applicant satisfy OLA requirements; restrictions in the deed of mutual covenant or Government lease can prevent the proposed use.

The Criminal Penalties

Operating without a license is a criminal offence, not a civil infringement. The penalties are:

• Unlicensed operation: Maximum fine of HK$500,000 and up to 3 years' imprisonment. A further fine of HK$20,000 for each day a continuing offence continues may also be imposed.
• Repeated offence: The Authority may apply to the court for a six-month closure order after a second conviction within 16 months for operating an unlicensed hotel or guesthouse, or for the relevant strict-liability offence, in respect of the same premises.

These are statutory maximum penalties. The OLA actively prosecutes unlicensed guesthouse operators.

The Enforcement Operation: Solar Flare and the OLA's Monitoring Capacity

The OLA operates a dedicated internet intelligence team that monitors websites, mobile applications, and social media platforms to identify unlicensed listings in Hong Kong. It also conducts coordinated enforcement operations, including surprise sweeps.

Operation Solar Flare is an example of the OLA's coordinated enforcement activity.

The OLA's approach has become more systematic. Do not assume that listing a property under a friend's name or a corporate account removes the legal and contractual risks.

The Insurance and Mortgage Problem

Beyond criminal liability, operating an unlicensed short-term rental can jeopardise two important protections:

Property insurance: Standard domestic property insurance policies in Hong Kong may exclude coverage for commercial hospitality activities. If a guest is injured, causes a fire, or damages the property during an unlicensed Airbnb stay, your insurer may deny the claim on the grounds of commercial use. You are exposed to personal liability for any injury or damage that occurs.

Mortgage conditions: Standard residential mortgage agreements from Hong Kong banks — HSBC, Hang Seng, Bank of China, and others — contain clauses stating that the property must be used for residential purposes and that any change of use requires prior written bank consent. Operating a short-term rental without disclosure can constitute a breach of these mortgage conditions. In theory (and in cases where a bank discovers the breach), this can trigger an acceleration clause requiring full repayment of the outstanding loan.

What Actually Generates Higher Yields in Hong Kong

Short-term Airbnb-style letting is possible in Hong Kong where the premises qualify for and obtain the appropriate Cap. 349 licence.

Investors seeking above-average yields in Hong Kong work within the long-term unfurnished rental market. The districts and property types generating the strongest net yields as of 2026 are not the obvious luxury locations:

• Class A and B apartments (under 70 sqm saleable area) in New Territories districts like Tuen Mun (gross yield ~3.95%) and To Kwa Wan (gross yield ~3.90%) outperform Central luxury units (gross yield ~3.44%) by 50–100 basis points gross, with smaller price tags that reduce absolute capital exposure.
• Proximity to university campuses and MTR lines drives consistent tenant demand in areas like Kennedy Town, Sai Ying Pun, and Sha Tin — where the tenant base includes HKU and CUHK students plus young professionals.
• New Territories lease terms: Under Cap. 648, applicable general-purpose leases without a right of renewal (or with the renewal right exercised) and expiring on or after 5 July 2024 are extended for 50 years if covered by an Extension Notice and not listed on the Non-extension List; short-term tenancies and special-purpose leases are excluded. This reduces 2047 expiry uncertainty for affected properties, making their yield advantage more durable than it was in previous years.

Serviced Apartments: The Legitimate High-Yield Alternative

Fully furnished serviced apartments do exist as a legitimate market in Hong Kong. Where a serviced apartment offers paid sleeping accommodation to persons presenting themselves and the 28-day exclusion does not apply, it needs the appropriate licence. Licensed guesthouses are not limited to purpose-built buildings: a general guesthouse licence may cover premises in a domestic building, subject to the requirements above.

The returns can be attractive, but the operational model is nothing like owning a residential flat. Serviced apartment operators are effectively running a hospitality business: they manage housekeeping, linen, utility bills, reception, and maintenance, and carry the overhead of a licensed operation. Returns are higher in gross terms but net margins are tighter due to operating costs, and the investment is in a commercial hospitality asset, not a standard residential property.

For a private investor with one or two properties, buying into an existing managed serviced apartment complex is one route. A private flat is not automatically barred from licensing; an operation involving stays of fewer than 28 days requires a licence only if it falls within Cap. 349's scope and no statutory exclusion applies.

The 28-Day Threshold in Practice

Some landlords attempt to structure stays of exactly 28 days or longer to stay outside Cap. 349. The exclusion applies only where every letting is for a minimum of 28 continuous days and no fee is waived, refunded or reduced if it is shortened below 28 days. This approach also has practical problems:

• Most actual short-term demand is for 1–14 days. Guests booking 28-day stays are effectively entering the long-term rental market and will negotiate accordingly.
• If a 28-day stay turns into a dispute over early termination or deposit, you need a properly stamped tenancy agreement to access the Lands Tribunal. This starts to look and function like a standard tenancy, not short-term accommodation.
• Banks and insurers assess use based on actual commercial practice, not the number on the contract. A pattern of sequential 28-day bookings to different guests could still trigger commercial use findings in an insurance context.

The Bottom Line for Investors

If you are evaluating a Hong Kong investment property with short-term rental income as part of the business plan, include that income only if it is lawful; where Cap. 349 applies and no statutory exclusion applies, the premises must qualify for and obtain an appropriate licence, and an operation that falls within its scope but cannot be licensed should be modelled as standard 12-month to 24-month residential tenancies at market rents.

Key Takeaways

• Operating a hotel or guesthouse within Cap. 349's scope without a valid licence is a criminal offence.
• A standard residential apartment is not automatically barred from licensing; it must satisfy the OLA's premises-specific building, fire-safety, and other requirements, including the no-use restriction check for the DMC or Government lease.
• First-offense penalties: up to HK$500,000 fine and 3 years' imprisonment.
• The OLA actively monitors Airbnb and other platforms and runs coordinated enforcement raids multiple times per year.
• Operating an unlicensed short-term rental can jeopardise property insurance coverage and breach standard mortgage conditions.
• One legitimate path to higher yields is long-term unfurnished letting in high-demand districts — particularly Class A/B units in New Territories and transit-connected areas.
