UBWs in New Territories Exempted Houses

Green and Amenity Facilities in NTEH

Some specified green and amenity facilities, whether they currently exist in the village houses or to be installed in new and existing village houses in future, can be allowed to stay or be installed at any time in future without seeking the permission from the Lands Department or the Buildings Department (BD), provided that the village house is a NTEH exempted under the Buildings Ordinance (Application to the New Territories) Ordinance.

Photovoltaic (PV) systems

Photovoltaic (PV) systems satisfying the following requirements may be installed on the roof or roof of stairhood in both new and existing New Territories Exempted Houses (NTEH):

System on roof

  • the system including its supporting structure should not be higher than 2.5m measured from the roof level.
  • the average loading imposed should not exceed 150kg/m2
  • it should not project more than 750mm from the external wall.
  • for system arranged in the form of continuous spread covering, its coverage (only the coverage area within the building is accounted) should not be more than half of the roofed-over area of the NTEH.
  • for system arranged in clusters, each cluster should have coverage of not more than 5m2 (only the coverage area within the building is accounted) and should be separated from each other by not less than 1m.

System on roof of stairhood

  • the system including its supporting structure should not be higher than 1.5m measured from the level of the roof of the stairhood.
  • the average loading imposed should not exceed 75kg/m2.
  • it should not project more than 750mm from the edge of the roof.

Common requirements

  • the roof on which the system would be installed should be cleared of all unauthorised building works (UBWs), including those acknowledged by the Buildings Department (BD) under the Reporting Scheme for UBWs in NTEH implemented by BD.
  • the space underneath the system should not be enclosed^.
  • the system should be properly installed and should not adversely affect the structural safety of the building. For system exceeding 1.5m high measured from the roof level, it should be certified by an Authorized Person registered under the Buildings Ordinance for submission of a safety certificate+ to Lands Department for record.
  • such facilities should not be installed on the canopy.

^ If the space is enclosed, BD will take enforcement action under the Buildings Ordinance.

+ The safety certificate (Form C/PVS) is available at Lands Department and all N.T. District Lands Offices. It can also be downloaded from Lands Department's website (https://www.landsd.gov.hk/).

Common concerns

For the system on the roof, the height of the system including its supporting structure should not be higher than 2.5m measured from the roof level to the highest point on the system.

For system on the roof, PV panels not more than 750mm can be projected from the external wall of the main building.

The whole system including the PV panels, the supporting frame and any uncovered space or gap between PV panels within the building is accounted. For an extensible structure, its coverage should be accounted when it is fully extended. As design and construction of the village houses are different, the actual coverage areas of the PV systems allowed on the roof are depending on the design of the NTEH. If the roofed-over area of the NTEH is 700 square feet, the coverage of the system arranged in the continuous spread covering (only the coverage area within the building is accounted) should not be more than 350 square feet.

For an extensible structure, the fully extended system should be measured for the coverage area. In this connection, for a system arranged in the form of continuous spread covering installed on an extensible structure, if its coverage area when fully extended, exceeds half of the roofed-over area of the NTEH according to the requirements, it will be considered as UBWs. The owners should also pay particular attention and ensure the structural safety of the extensible structure and the safety of the electrical installations on it.

According to the requirements, the roof on which the system would be installed should be cleared of all UBWs, including those reported and acknowledged by the Buildings Department (BD) under the Reporting Scheme for UBWs in NTEH implemented by BD. Therefore, the existing reported UBWs should be removed.

No, according to the requirements, the roof on which the system installed should be cleared of all UBWs, including those reported and acknowledged by the Buildings Department (BD) under the Reporting Scheme for UBWs in NTEH implemented by BD. Thus, the existing UBWs should be removed. Therefore, PV panels installed on the UBWs on the roof would also be regarded as UBWs. BD would take enforcement action in accordance with the enhanced enforcement strategy against UBWs in NTEHs.

The safety certificate Form C/PVS is available at Lands Department and all N.T. District Lands Offices. It can also be downloaded from Lands Department's website (http://www.landsd.gov.hk).

If any part of the system installed on the roof exceeded 1.5m high measured from the roof level, the whole system in NTEH including those not exceeding than 1.5m (such as the system installed on roof of the stairhood, if any) should be certified by an Authorized Person registered under the Buildings Ordinance for submission of a safety certificate to Lands Department for record.

The space underneath the PV system should not be enclosed in any form and any extent. It would be considered as enclosed and not satisfy with relevant requirements when such space is fully or partially enclosed by any fixed or movable components constructed of canvas, metal or glass, prefabricated storage cabinets (regardless of whether they are considered as green and amenity facilities in NTEH) or PV panels and equipment associated with the PV system. It is necessary to avoid such space be enclosed in the design of the system.

To promote the development of renewable energy, the Government suitably relaxed the restrictions on installation of solar PV systems on the rooftops of NTEH. Subject to the fulfilment of requirements for PV systems that may be installed on the roof or roof of stairhood in NTEH, PV systems not greater than 2.5 metres in height may be installed on the rooftops of NTEH. For the design of PV systems, you should also pay attention to the relevant requirements of other government departments, including the Electrical and Mechanical Services Department (EMSD) and the Fire Services Department. For details of such requirements, please refer to the Guidance Notes for Solar Photovoltaic System Installation published by EMSD. If you would like to participate in the FiT Scheme, please visit the Hong Kong Renewable Energy Net (https://re.emsd.gov.hk) for details.
