Unauthorized construction
What should I do if I receive a demolition order for illegal structures? |
---|
Receiving a removal order for an illegal building (UBW) can be stressful, but it is important to stay calm and take the right steps. The following are specific treatment suggestions: Confirm the details of the removal order Read the notice carefully: confirm the location of the alleged UBW, the type of structure (such as rooftops, canopies, partition walls, etc.), the legal basis and the deadline for removal. Clarify responsibilities: Confirm that you are the owner or responsible person. If the property has been rented out or transferred, you need to confirm who has legal liability. Consult professionals Hire an approved person (such as an architect, surveyor or engineer): Hong Kong's Buildings Ordinance stipulates that the demolition or rectification of unauthorized building works must be carried out by an "authorized person" who submits a plan to the Buildings Department (if applicable). Professionals can help assess whether a building is indeed illegal, propose remedial options (such as the possibility of applying for "legalization") or plan a safe demolition process. Legal advice: If you have any disputes about the demolition order (for example, if you think the government has made an error in its judgment), you should consult a lawyer to find out whether you can file an appeal or seek judicial review. Submit an appeal or extension request (if applicable) Complaint channels: If you believe that the removal order is wrong (for example, the illegal building has actually been legalized), you can submit a written appeal to the relevant department (such as the Buildings Department) within the specified period (usually 14 to 28 days after receiving the notice), and attach evidence (such as previous approval documents, plans, etc.). Application for extension of time for demolition: If more time is needed (such as arranging works or funds), you may apply for an extension in writing and state reasonable reasons (for example, the rainy season affects construction safety). Arrange for compliant demolition Hiring Qualified Contractors: According to the law, demolition works may need to be carried out by registered contractors, especially those involving structural safety (such as demolition of supporting walls, height work, etc.). Submit the certificate of completion: After demolition, in some cases an approved person needs to submit a completion report to the government to confirm that the requirements are met. Consequences of not handling in time Fines and Imprisonment: Failure to demolish the buildings within the deadline may result in criminal prosecution, with a maximum fine of hundreds of thousands of Hong Kong dollars and imprisonment (the maximum fine under Hong Kong law is HK$200,000 and imprisonment for 2 years). Enforcement: The government may directly commission a contractor to carry out demolition and the costs will be borne by the owner (the costs may be much higher than the cost of handling it yourself). Subsequent Notes Keep all documents: including demolition orders, correspondence, work receipts, etc., for future use in case of disputes or property transactions. Preventing recidivism: Before carrying out any additions or alterations, be sure to apply for approval from the Buildings Department and ensure that they comply with the Buildings Ordinance and the lease conditions. Special situation handling Historical Unauthorized Structures: Some old buildings with long-standing illegal structures (e.g. before the 1980s) may be eligible for a "demolition deferral" (which requires professional assessment). Buildings of joint owners: If the illegal structures involve the common areas of the building (such as the exterior walls), it is necessary to coordinate with other owners and the management company to share the responsibilities. Key principles: Avoid delaying or ignoring demolition orders, proactively communicate and seek professional assistance, which can effectively reduce legal risks and economic losses. |
Cases of non-compliance with removal orders
Three property owners fined a total of more than $370,000 for failing to comply with removal orders |
---|
Three owners were convicted and fined a total of more than $370,000 at the Tuen Mun and Fanling Magistrates' Courts last month and early this month for failing to comply with removal orders issued under the Buildings Ordinance (Cap. 123). The first case involved three structures on the rooftop of an industrial building on Kin Tai Street, Tuen Mun, with a total area of about 900 square meters. As the unauthorised structures had not been constructed with the prior approval and consent of the Buildings Department, the Buildings Department issued three removal orders to the relevant owners under section 24(1) of the Buildings Ordinance. As the owner failed to comply with the demolition order, he was prosecuted by the Buildings Department and was convicted and fined a total of $193,500 at the Tuen Mun Magistrates' Courts on last month 31, of which $103,500 was a fine for the number of days the offence had continued. The second case involved several unauthorised structures on the terrace and rooftop of a village house in San Uk Ka, Tai Po, with a total area of about 32 square metres. The unit involved was jointly owned by two owners. As the UBWs concerned would not be issued with an exemption certificate by the Lands Department and the UBWs concerned had not obtained prior approval and consent from the Buildings Department, the Buildings Department issued a Removal Order to the relevant owner under section 24(1) of the Buildings Ordinance. As the two owners failed to comply with the demolition orders, they were prosecuted by the Buildings Department and were convicted and fined a total of $179,400 at the Fanling Magistrates' Courts on the 28th of last month and the 4th of this month respectively, of which $149,400 was a fine for the number of days the offence had continued. A spokesman for the Buildings Department said today (June 18), "UBWs can lead to serious consequences. Owners must comply with removal orders as soon as possible. The Buildings Department will continue to take enforcement actions, including prosecution, against owners who fail to comply with removal orders to protect building safety." Under the Buildings Ordinance, any person who fails to comply with a demolition order without reasonable excuse is committing a serious offence and, upon conviction, is liable to a maximum fine of $200,000 and one year's imprisonment, and a further fine of $20,000 for each day the offence continues. over June 18, 2024 (Tuesday) HKT 11:00 |
Owner sentenced to suspended prison sentence for repeatedly failing to comply with removal orders |
---|
An owner was convicted and sentenced to 14 days' imprisonment, suspended for 18 months, and fined over $31,000 at the Tuen Mun Magistrates' Courts on 15th last month for persistently failing to comply with a removal order issued under the Buildings Ordinance (Cap. 123). The case involved a unit in a three-storey building in Yu Chui Street, Tai Lam, Tuen Mun. The unauthorised building works included the removal of slopes, the construction of additional walls and stairs, the removal of protective railings, and the construction of additional structures in the garden on the first floor, involving a total area of about 70 square metres. As the UBWs had not been approved and agreed to in advance by the Buildings Department, the Buildings Department issued a removal order to the relevant owner under Section 24(1) of the Buildings Ordinance. As the owner failed to comply with the demolition order, he was prosecuted by the Buildings Department in 2022, convicted by the court and fined $10,000. Although the owner subsequently demolished the structures in the garden on the first floor, he did not comply with all the requirements of the demolition order, including repairing the slope and protective railings in accordance with the approved plans, and demolishing the remaining illegal structures. The Buildings Department initiated prosecution again in 2023 and the owner was again convicted by the court and fined more than $10,600. As the owner still failed to comply with all the requirements of the demolition order, the Buildings Department initiated a third prosecution. The owner was convicted again at the Tuen Mun Magistrates' Courts on the 15th of last month and was sentenced to 14 days' imprisonment, suspended for 18 months, and fined a total of $31,020. A spokesman for the Buildings Department said today (December 2), "UBWs can lead to serious consequences. The owners concerned must comply with the removal orders as soon as possible. The Buildings Department will continue to take enforcement action against owners who have not complied with the removal orders and will initiate prosecution again to safeguard building safety." Under the Buildings Ordinance, any person who fails to comply with a demolition order without reasonable excuse is committing a serious offence and, upon conviction, is liable to a maximum fine of $200,000 and one year's imprisonment, and a further fine of $20,000 for each day the offence continues.

The two co-owners were convicted and fined more than $90,000 at the Tuen Mun Magistrates' Courts late last month for failing to comply with a removal order issued under the Buildings Ordinance (Cap. 123). The case involved a courtyard structure of about 20 square metres next to a detached house in Yuen Long. The UBW was not approved and agreed to by the Buildings Department (BD). The BD then issued a removal order to the relevant owner under section 24(1) of the Buildings Ordinance. As the owner concerned failed to comply with the demolition order, he was prosecuted by the Buildings Department and was convicted and fined a total of $92,280 at the Tuen Mun Magistrates' Courts on 27th last month, of which $82,280 was a fine for the number of days the offence had continued. A spokesman for the Buildings Department said today (January 8), "UBWs can lead to serious consequences. Owners must comply with removal orders as soon as possible. The Buildings Department will continue to take enforcement actions, including prosecution, against owners who fail to comply with removal orders to safeguard building safety." Under the Buildings Ordinance, any person who fails to comply with a demolition order without reasonable excuse is committing a serious offence and, upon conviction, is liable to a maximum fine of $200,000 and one year's imprisonment, as well as a further fine of $20,000 for each day the offence continues. over January 8, 2025 (Wednesday) HKT 11:00 |

How does the Buildings Department verify new unauthorized building works?
The Buildings Department adopts the following measures to monitor and verify new UBWs:
Refer to the bird's-eye view photos to identify new unauthorized structures on the rooftop.
Maintain photographic records of buildings to verify the condition of new UBWs.
The results of the comprehensive inquiry and circumstantial evidence.
If I want to build a storage locker on the rooftop of my property, do I need to obtain approval and consent from the Buildings Department?
need. You must obtain prior approval and consent from the Buildings Department before erecting prefabricated structures on the main roof, platform or patio of a building, including mobile homes and large storage cabinets with a volume exceeding 3 cubic metres or a height exceeding 2 metres, or glass houses. You must appoint an Authorized Person to submit the building plans to the Buildings Department and coordinate the building works. After obtaining the approval and consent from the Buildings Department, you must appoint a Registered General Building Contractor to carry out the works. ShouldSuch works cannot be carried out by registered minor works contractors. Any person who violates the above requirements may be subject to prosecution and/or disciplinary action under the Buildings Ordinance. Any such structures constructed in violation of the above requirements are considered unauthorized buildings and the Buildings Department will take enforcement action.
If a prefabricated locker with a volume not exceeding 3 cubic metres and a height not exceeding 2 metres is built on the main roof, platform or patio, the owner should ensure that the locker is stable and comply with the following requirements:
The lockers will not damage the building structure;
The lockers do not block the building's fire escapes or fire shelters; and
The lockers will not affect the building's drainage system.
Will the payment of property taxes or rates make illegal structures legal?
Won't
Under what circumstances will the authorities take enforcement action under the Buildings Ordinance in relation to building works related to environmentally friendly balconies and utility platforms as specified in item (h) of the Buildings Department's Policy on Removal of Unauthorized Building Works 2011?
If physical alterations are found to approved green balconies and utility platforms, the authorities will take immediate enforcement action under the Buildings Ordinance against the alteration works carried out/carried out under the following circumstances:
without obtaining prior approval and consent from the Buildings Department; or
Adopting the simplified requirements of the Minor Works Control System, but violating the provisions of the Buildings Ordinance and related regulations.
Would it be a violation of the Buildings Ordinance if the partition wall between two adjacent units, both of which have environmentally friendly balconies and utility platforms, is demolished?
The demolition of the partition wall between two adjacent units, both of which have environmentally friendly balconies and working platforms, may involve structural components and violate the Buildings Ordinance. The alteration works involved may also violate other provisions of the Buildings Ordinance and relevant regulations, such as the exemption criteria for environmentally friendly balconies and working platforms for the buildings concerned. Owners should seek advice from an Authorized Person before commencing demolition works and, where necessary, submit a formal application to the Buildings Department for approval and consent.
Owners/occupiers affected by enforcement actions to remove illegal rooftop structures in industrial buildings may encounter financial difficulties or become homeless. Will the Buildings Department provide assistance?
Owners who are experiencing financial difficulties may apply for a loan under the Building Safety Loan Scheme implemented by the Buildings Department to cover the cost of carrying out the necessary works to comply with a removal order.
Unauthorized rooftop structures in industrial buildings should not be converted for domestic use as this is inconsistent with the original intended use of the buildings. Under the existing policy, when the Buildings Department takes enforcement action to remove illegal rooftop structures used for residential purposes in industrial buildings, the Housing Department will not provide housing rehousing to the affected occupants. However, the Buildings Department will liaise with the Housing Department to arrange beds in temporary shelters for those in urgent housing needs. In addition, affected occupiers may also seek assistance from the Social Welfare Department.
What are the consequences of not complying with a statutory order to remove unauthorized building works?
If the owner fails to comply with the order, the Buildings Department will entrust a government contractor to carry out the demolition and demolition work on his behalf, and will then recover the full cost of the project from the owner, plus supervision fees and surcharges.
Failure to comply with a statutory order is a criminal offence, with a maximum penalty of one year's imprisonment and a fine of HK$200,000. If the violation continues, an additional fine of HK$20,000 per day will be imposed.
The Land Registry will also record the order. If the property is mortgaged, the relevant financial institutions will be informed of the order.
For more information, please refer toOwner's Responsibilities.
Is it necessary to appoint an Authorized Person to carry out the removal of unauthorized building works?
Please refer to your removal order:
If a removal order requires the demolition of a building or any major or significant part of a building, the Buildings Department will specify in the removal order whether the owner is required to appoint an authorized person, a registered specialist contractor and a registered structural engineer to carry out the works, provide advice and ensure that necessary safety measures are provided.
If the works required by a removal order do not involve the demolition of a building or the demolition of any major or significant part of a building, the Buildings Department will not specify in the removal order that the owner must appoint an authorized person, a registered contractor and a registered structural engineer. However, for personal and public safety, the Buildings Department will advise owners to appoint registered contractors to carry out the works, and appoint authorized persons or registered structural engineers to ensure that the necessary safety measures are provided. Furthermore, the Building (Minor Works) Regulations came into operation on 31 December 2010. Under the new "Minor Works Control System", persons who intend to carry out minor works can do so through simplified procedures. For details of the Minor Works Control System, please call the Buildings Department hotline at 2626 1616 or visitOur website.
I have just received an order from the Buildings Department. Can I request an extension for the construction works?
You can submit your application in writing to the Buildings Department, stating the reasons for the extension. However, unless it is a very special case, the Buildings Department will usually not approve such a request (for example, on the grounds that “the building has been rented out”). You should therefore comply with the provisions of the order as quickly as possible to avoid delay. If the order is not complied with without reasonable explanation, the person may be prosecuted and/or have the works carried out by a government contractor. The Buildings Department will then recover the cost of the works from you, plus a supervision fee and a surcharge.
How do I know whether the Buildings Department has issued any order in respect of my building which has not been complied with?
It is not a requirement under the Buildings Ordinance for the Buildings Department to register a statutory order issued by it with the Land Registry. However, under the current procedures, the Buildings Department will send the statutory order to the Land Registry for registration and will cancel it after the order is complied with. You can inspect the records kept by the Land Registry (please refer to the Land Registry - FAQ - Search https://www.landreg.gov.hk/tc/faq/faq_search.html). Some statutory orders issued earlier may not yet be registered with the Land Registry.
In addition, the Buildings Department is now launching a tool that allows the public to search the compliance status of statutory orders on the Department's website. In the first phase, members of the public can now search the compliance status of statutory orders issued under sections 24 (only for drainage services), 26, 26A and 28 of the Buildings Ordinance in 2021 and thereafter on the Buildings Department's website (https://www.bd.gov.hk/tc/resources/online-tools/orders-search/ordersearch-disclaimer.html).
Please note that even if there is no statutory order on the premises, it does not mean that there are no unauthorized structures on the premises. In addition, prospective property purchasers are advised to inspect the property they intend to purchase and to consult the Building Information Centre of the Buildings Department or on the Internet."Bailoutu.com" Check the relevant approved plans and minor works records and seek advice from professionals when necessary to ensure that there are no unauthorized building works on the property. You can also obtain relevant information from the property seller or contact the Buildings Department.
Under what circumstances will the Buildings Department carry out works on behalf of the owner?
The owner is obliged to comply with the orders issued by the Building Authority. Only in an emergency or when the owner fails to comply with the order will the Buildings Department carry out the works on behalf of the owner and then recover the cost of the works, plus supervision fees and surcharges, from the owner. The Buildings Department may take prosecution action against owners who fail to comply with the order without reasonable excuse. Under the Buildings Ordinance, any person who fails to comply with an order without reasonable excuse commits an offence and is liable to a fine and imprisonment upon conviction.
I am the occupant of an illegal rooftop structure affected by a removal order from the Buildings Department and will be rendered homeless as a result of the demolition work. Will the Buildings Department provide me with assistance?
It is Government policy that no one will be rendered homeless as a result of Government action. Although rooftop structures are illegal structures, the Buildings Department has made arrangements with the Housing Department, the Social Welfare Department and the Home Affairs Department in accordance with this policy to provide rehousing and social security assistance to the occupants concerned. As for the types of rehousing eligibility, it falls under the jurisdiction of the Housing Department, which will make an assessment based on the rehousing eligibility of the affected occupants.
If I want to lodge a statutory appeal under section 44 of the Buildings Ordinance against a decision made by the Building Authority, such as an order to remove unauthorized building works, what should I do?

Are modular homes legal?
A spokesman for the Buildings Department said today (Sunday) that all prefabricated structures including modular houses, large storage cabinets and prefabricated houses must be approved by the Building Authority before construction can commence.
The spokesperson made the above appeal when talking about a recent appeal case. In this case, the appellant failed to comply with the demolition order and claimed that the prefabricated structure on the rooftop of his property was just a storage cabinet and not a construction project.
In dismissing the appeal, the Appeal Tribunal ruled that under the Buildings Ordinance, the definition of building works includes prefabricated structures, which must first be approved by the Building Authority.
The spokesman stressed that these prefabricated structures increased the total floor area and were not in compliance with the approved building plans. These structures generally affect lighting and ventilation systems, fire escape routes, and increase the load on the building and adjacent buildings.
The spokesman urged consumers not to be misled by product advertisements claiming that these prefabricated structures do not violate the Buildings Ordinance. Consumers must think twice before undertaking remodeling projects at home.
Under the Buildings Ordinance, exempted works generally refer to construction works carried out in a building that do not involve the building structure and do not violate any regulations.
For example, lockers with a height not exceeding 1.5 metres, not exceeding the height of the parapet and not affecting the drainage system are acceptable.
The spokesman reminded members of the public that many fixed installations in buildings, although of a minor nature, are not exempted works.
He said: "The unauthorised fixed installations that the Building Authority will not order for immediate removal include iron gates that do not block fire escape routes, open wire mesh enclosures on roofs that extend no more than two metres for security purposes, retractable canvas covers that extend no more than two metres from external walls and are no higher than 2.5 metres from the main roof and platform of multiple staircases, light air-conditioning racks and light window covers that extend no more than 500 millimetres from external walls, and clothes drying racks."
If you have any questions, you may call the Buildings Department's Building Safety Hotline at 2626 1234 or consult an authorized person.
In the first half of this year, the Buildings Department issued a total of 1,694 statutory orders to demolish unauthorized building works, compared with a total of 3,103 issued last year.
In the first six months of this year, a total of 1,580 statutory orders were executed, compared with 2,722 statutory orders executed last year.

Is it possible for the base of a modular house to not touch the ground?
In the New Territories, many building materials companies provide installation services for modular houses, and some of them even provide customized services. However, the practice of building modular houses on rooftops is considered a "grey area" because although these modular houses do not directly touch the ground, they do not necessarily comply with all building regulations. Under Hong Kong's Building Regulations, any building structure, whether or not it touches the ground, needs to comply with relevant safety standards and obtain necessary approvals. The Buildings Department can ask you to demolish it.
The installation process of modular house
- Ordering and waiting time: After the customer places an order, it usually takes 5 to 6 weeks for the building materials company to arrange workers to bring the materials to the site for installation.
- Materials and prices: The main material of modular houses is steel, and the price varies according to size and function. For example:
- An 80-square-foot (8ft x 10ft x 7ft3) modular house costs about HK$22,600, including wooden flooring.
- A 24-square-foot bathroom, which costs about HK$15,000, includes an aluminum floor and is waterproof, rust-proof and heat-insulating.
- Installation time: Modular homes and restrooms can usually be installed in one day.
Cost Estimation
Taking Mr. Chen’s case as an example, he built 5 modular houses and a bathroom on the rooftop, with a total cost of about HK$140,000. If scaffolding is required, an additional fee of HK$3,000 will be charged.
Risks and recommendations
- Legal risks: Although these modular houses do not directly touch the ground, they may still be considered illegal buildings if they are not approved by relevant departments and face the risk of demolition or fines.
- Concealment: Staff reminded that the area of the modular house should not be too large to avoid attracting attention. It is usually recommended to build a modular house of more than 100 square feet to avoid being too conspicuous.
Practical advice to property owners
- Quantitative risk assessment
Before deciding to build, you should hire an approved person to verify:
- Rooftop residual load capacity (structural engineer report required)
- Does the projection area of the modular house exceed the top floor area? 50%
- Is there a channel of at least 1.5 meters at the edge of the roof?
- Stop loss plan preset
You can ask the building materials company to sign a "demolition and repurchase agreement", stipulating that if you are ordered to demolish, the company will recycle the materials at the original price of 60-70% to reduce potential losses. - Insurance availability
Some insurance companies have launched "Temporary Structure Accident Insurance" with an annual premium of approximately 1.5% of the construction cost, covering wind damage and third-party liability, but proof of structural safety is required.
Although building a modular house on the rooftop seems convenient and relatively low-cost, there are certain legal risks. It is recommended that you consult professionals or relevant government departments before undertaking such projects to ensure that all building regulations are met to avoid possible legal problems in the future.

Water seepage problem
Nuisance Notice/Order
