Except as otherwise specified in this Code, all notices issued by the Zoning Administrator must be served on:the person for whom the notice is intended; or an authorized agent or representative of that person. If more than 1 person is responsible for the violation or otherwise responsible for complying with this Code, as in a case of property owned by more than 1 person, notice may be served on any 1 of those persons or on any authorized agent or representative of any of them. A notice is properly served on a person if:served personally on that person (or on that person’s authorized agent or representative); hand-delivered to the home or business address of that person (or of that person’s authorized agent or representative); or sent by certified or registered mail, return receipt requested, to the home or business address of that person (or of that person’s authorized agent or representative). Adequate and sufficient notice may be made by posting a copy of the notice on the property in question if:the identity or whereabouts of the person responsible is unknown; or a notice that was hand-delivered or mailed under subsection (c) of this section is refused, returned unclaimed, or designated undeliverable by the post office for any reason, and neither of the following sources can provide a more accurate address:the tax records of the City’s Bureau of Treasury Management, Collections Division; and the property registration files of the Department of Housing and Community Development.
