Before carrying out the demolition of unauthorized structures, building professionals and contractors must conduct a comprehensive site survey and risk assessment. This includes a detailed examination of the structural integrity of the building, the condition of materials, and surrounding environmental factors, to identify potential safety hazards and technical challenges. Based on the assessment results, a thorough dismantling plan should be developed.
In addition to engineering and technical aspects, the demolition of unauthorized structures involves various legal regulations. Building professionals and property owners must be familiar with and comply with the Buildings Ordinance, the Fire Services Ordinance, the Environmental Protection Ordinance, and other relevant regulations to ensure the legality and compliance of the project. Before construction, it may also be necessary to obtain demolition permits from relevant government departments and submit materials such as safety assessment reports and environmental assessment reports.

Familiar with building structure systems
Unauthorized structures are usually built without professional design and approval, and their structural safety is not guaranteed. Illegal additions may exceed the original structural load design of the building, and long-term excessive loads may cause structural deformation, cracking, damage, or even lead to collapse incidents.
Many rooftop extensions are used for residential, storage, and other purposes, but due to a lack of compliant drainage, ventilation, lighting, and other facilities, the sanitary conditions are concerning, fostering mosquito and rodent problems. Some extensions also illegally occupy public space or block passages, causing inconvenience to the daily lives of other residents.
Make the environment worse
The rooftop extensions have destroyed the original facade effect and skyline of the buildings, bringing negative impacts to the urban landscape. The chaotic extensions make the appearance of the buildings uncoordinated and unattractive. Some low-quality building materials, such as asphalt felt and plastic boards, also affect the visual appeal and lower the environmental quality.
Hindering good management of buildings
Illegal structures have brought additional workload and management difficulties to property management. Issues such as illegal residency, excessive electrical loads, random wiring, and improper plumbing not only increase management costs but also pose safety risks. Illegal occupants often lack civic awareness, causing damage to public facilities and affecting the interests of other owners.
Anyone who fails to comply with orders without reasonable justification is committing an offense.
According to Hong Kong Law Chapter 123《Building Ordinance》, owners should proactively arrange for the demolition of unauthorized structures within the premises. Owners may hire professional demolition contractors to ensure that the demolition work is carried out safely, compliantly, and efficiently. As for unauthorized structures in the common areas of the building, the owners' corporation or co-owners should work together to demolish.
Failure to comply with statutory orders is a criminal offense. According to 《Building Ordinance》, anyone who fails to comply with an order without reasonable excuse will be guilty of an offense and, upon conviction, may be punished with a fine and imprisonment. The maximum penalty is imprisonment for 1 year and a fine of HKD 200,000. If the violation continues, an additional fine of HKD 20,000 per day may be imposed. Relevant orders will also be recorded at the Land Registry. If the owner does not comply with the order, the Buildings Department will instruct government contractors to carry out the demolition and then recover the costs from the owner, plus supervision fees and additional charges.
