Proper service of such notices shall be by personal service, residence service or by registered mail; provided, however, that such notice shall be deemed to be properly served if a copy thereof is sent by registered mail to the last known address. If any of the parties cannot be located, nor can the address be ascertained, notice shall be deemed to be properly served if a copy thereof is placed in a conspicuous place in or about the building or structure affected by this notice. If such notice is by registered mail, the thirty-day period or shorter period, within which the owner is required to comply with the order of the Fire Chief, shall begin as of the date he received such notice.
