Mandatory Window Inspection Scheme

Overview of MWIS

Overview

Building neglect has been a long-standing problem in Hong Kong. The presence of ageing buildings which lack proper care and maintenance poses potential threats to residents and the public at large.

To tackle the neglect problems, full implementation of the MWIS as well as the MBIS commenced on 30 June 2012.

Selection of Target Buildings

Target buildings are selected each year for implementation of MWIS.

A selection panel comprising representatives from professional institutions, non-government organisations, property management professionals, District Councils and relevant Government departments is established to render advice to the BD for the selection of target buildings for MWIS.

A risk-based approach is adopted, taking into account the factors below in selection of target buildings:

  • Condition of the windows
  • Repair records of the windows
  • Record of reports on the dilapidated condition of the windows

Higher priority may be given to those buildings with windows in a generally defective or dilapidated state, posing relatively higher potential risk to the public.

Time Frame

Windows in Individual Premises
Appointment of a Qualified Person to complete the prescribed inspection and prescribed repair (if find necessary) within 6 months from the date of the statutory notice.
Windows in Common Parts of a Building (irrespective of whether there is an Owners' Corporation or not)
Appointment of a Qualified Person to complete the prescribed inspection and prescribed repair (if find necessary) within 9 months from the date of the statutory notice.

Building age is calculated according to the date of the occupation permit issued by the Building Authority (BA).

After a notice (the preceding notice) has been complied with, a fresh notice in respect of the same window must not be served under the MWIS before the expiry of 5 years after the date of the preceding notice.

Legislation & Enforcement

MWIS was introduced with the enactment of relevant amendments to the Buildings Ordinance through the Buildings (Amendment) Ordinance 2011 in June 2011 and the subsidiary legislation including the Building (Inspection and Repair) Regulation in December 2011.
