Air-conditioners generate condensation. The vast majority of models of air-conditioners require the installation of a dripping pan and connecting hose for the discharge of water. If the discharge facilities are not properly maintained, especially after a heavy rain or typhoon, water dripping may occur.

A. Civil liability

Water dripping from an air-conditioner which causes substantial and unreasonable interference with the use and enjoyment of a flat below constitutes a nuisance.

B. Criminal liability

The discharge of water, whether waste or otherwise, from the ventilating system (e.g. air-conditioner) in any premises in such a manner as to be a nuisance constitutes a statutory nuisance under the Public Health and Municipal Services Ordinance ( Cap. 132 of the Laws of Hong Kong).

C. Assistance

The FEHD is responsible for the handling of nuisance to environmental hygiene caused by water dripping from air-conditioners. You can make a complaint to the FEHD if you find water dripping from an air-conditioner.

Please note that water dripping from air-conditioner in public housing estates (except food premises) is handled by the Housing Department. For Rental Housing Estates owned by the Housing Society, you have to contact the management office of the concerned estate.
