Service notice
55. (1) Every notice, other than a public notice, and every bill, issued under this Ordinance shall, unless it is under this Ordinance otherwise expressly provided, be served or presented-
(a) by giving or tendering the notice or bill, or sending it by registered post, to the person to whom it is addressed; or
(b) if such person cannot be found, then by leaving the notice or bill at his last known place of abode, or by giving or tendering it to some adult male member or servant of his family, ordinarily residing with him, or by causing it to be affixed on some conspicuous part of the building or land to which it relates.
(2) When a notice is required or permitted under this Ordinance to be served upon an owner, occupier or tenant, as the case may be, of a building or land, it shall not be necessary to name the owner, occupier or tenant therein, and the service thereof, in cases not otherwise specially provided for in this Ordinance, shall be effected either-
(a) by giving or tendering the notice, or sending it by post to the owner, occupier or tenant, or, if there be more owners, occupiers or tenants than one, to any of them; or
(b) if such owner, occupier or tenant cannot be found, then by giving or tendering the notice to an adult male member or servant of his family ordinarily residing with him, or by causing the notice to be affixed on some conspicuous part of the building or land to which it relates.
(3) Whenever the person on whom a notice or bill is to be served is a minor, service upon his guardian or upon an adult male member or servant or his family ordinarily residing with him shall be deemed to be service upon the minor.
