Risks of Renting Industrial or Commercial Units in Hong Kong
🎧 Listen to this article

Whether you are a landlord planning to convert an industrial building for rental or a tenant considering renting such a unit, you need to understand the restrictions of relevant laws (such as the Buildings Ordinance) and lease conditions. This article explains the risks of using industrial and commercial buildings for residential purposes and basic responses when receiving enforcement notices.
What are "industrial building subdivided units" and "commercial-to-residential"?
In Hong Kong, when a building is completed, the Buildings Department issues an Occupation Permit (commonly known as the "OP"), and the Lands Department's lease specifies the land use (e.g., industrial or commercial).
Industrial building subdivided units: Units originally for industrial use are partitioned into multiple living spaces by adding partitions, toilets, or drainage facilities.
Commercial-to-residential: Office or commercial units are used for residential purposes.
Without approval from relevant authorities (e.g., without applying for a lease modification or obtaining Buildings Department approval for the works), the above situations may involve breaches of lease conditions or the Buildings Ordinance.
Legal liabilities and risks landlords may face
Some landlords carry out alterations and rentals without approval. If discovered by enforcement authorities, they may face the following consequences:
1. Breach of the Buildings Ordinance
If the alteration works are unauthorized building works (e.g., changing partitions, drainage, or fire services), the Buildings Department may issue statutory orders (such as demolition orders) requiring restoration of the unit within a specified period.
Possible consequences:
- Failure to comply may result in fines and criminal liability
- Continuing non-compliance may involve daily fines
2. Breach of lease conditions
Using industrial or commercial units for residential purposes may violate land use restrictions.
The Lands Department may take action, including:
- Issuing warning letters and registering them with the Land Registry (commonly known as "caveat")
- Affecting the resale or mortgage of the property
In more serious or persistent breaches, the government may consider further action under relevant laws, including re-entry of the land.
Landlords may face significant financial consequences.
3. Insurance and mortgage risks
If the property use does not match the policy or mortgage terms:
- Insurance companies may refuse part or all of the claim under policy terms
- Banks may demand early repayment of the loan in certain circumstances
Risks for tenants
Renting industrial building subdivided units or commercial-to-residential units may also involve the following risks:
1. Safety risks
Design standards for industrial and commercial buildings are usually not based on residential use, such as:
- Fire services installation
- Escape route design
- Ventilation and separation arrangements
Past fire incidents involving industrial units reflect such risks.
2. Possible need to move out
If the Buildings Department issues a demolition order or closure order, or if the unit is subject to enforcement:
- Tenants may need to vacate within a specified period
- Actual arrangements depend on the specific enforcement procedures and circumstances
3. Deposit risks
If the tenancy agreement involves a unit not permitted for the intended use:
- The legal validity of the tenancy may be affected
- Tenants may face difficulties in recovering deposits from landlords
Basic checks before renting
To reduce risks, tenants and buyers can conduct basic checks before transactions:
1. Check the land register
Through the Land Registry's search, you can find out:
- Whether there are outstanding Buildings Department orders (e.g., demolition orders)
- Whether it involves Lands Department warning letters
- Whether there are other legal documents
2. Check the Occupation Permit
Confirm the approved use of the property, such as whether it is:
- "Residential" use
Industrial building subdivided units and commercial-to-residential units do exist in the market, but such arrangements may involve legal, contractual, and safety risks. Whether you are a landlord or a tenant, you should fully understand the property use restrictions and related responsibilities before making decisions, and conduct necessary checks to reduce potential risks.
