Hong Kong Housing Authority and Housing Department

Structural Safety Guarantee (HOS)

Structural Safety Guarantee (HOS)
The Hong Kong Housing Authority (HA) endorsed in 2000 to provide Structural Safety Guarantee (SSG) to the owners (Note 1) of newly constructed flats and the flats completed then under the Home Ownership Scheme (HOS) and the Private Sector Participation Scheme (PSPS). Also, HA endorsed in 2016 to provide SSG to owners (Note 1) of newly constructed flats under the Green Form Home Ownership Scheme (GSH).


The HA guarantees the structural stability and integrity of the building as a whole and undertakes all structural repairs (Note 2), including repair to concrete spalling and cracking, to any or all of the structural components (Note 3) deemed necessary to uphold the overall structural stability and integrity (Note 4) of the building (Note 5) within the 10-year SSG period (a 20-year SSG period for HOS courts in Tin Shui Wai Area).

Works of repairs not falling within the above-defined scope shall not be covered by this SSG, for example:

  (1) water seepage through ceilings, windows or walls, cracks in plaster and rendering, defects in wall and floor tiling and any other defects not related to the structural stability and integrity of the building;
  (2) defects arising from structural alterations or additions or changes within flats or improper usage of the building; and
  (3) defects arising from the following special risks, including:
  • explosions caused by inflammable gas;
  • an outbreak of war, fire, earthquake or landslide;
  • acts or omission of a person for whom the HA is not responsible.

Submission of Application

Structural Safety Guarantee Repair Application Form, obtainable from the property management office, should be duly completed and returned, together with proof of ownership (such as Demand Note for Rates) and photographs illustrating the defects, to the property management office for follow-up within the guarantee period.

Workflow of Application Processing

The Housing Department (HD) will process all applications promptly. We will conduct site investigations and record the findings. Having scrutinised the findings, we will inform the owners or the property management office in writing of whether the repairs fall within the scope of SSG. Should the repairs be covered by SSG, we will arrange repair works as soon as possible.

Standard of Reinstatement

Structural repair works will be carried out to reinstate the affected parts in the flat to their original standards at the time of building completion, with minimal alterations to the owner’s original decoration, furniture and fittings in the flat.

Owners’ Responsibility

To ensure that the HA can implement and perform its obligations under the SSG, owners shall allow the HA or its authorised personnel, upon production of their authorisation proof, to enter the premises concerned or any part thereof at reasonable times for inspection or carrying out related inspection and repair works.

Within the guarantee period, if the owners note that it is necessary for the HA to carry out structural repairs under the SSG, they must inform the HA in the first instance. Otherwise, the HA may not be able to fulfill its obligations under the SSG.

For enquiries, please contact the staff at the property management office.
