(a) The county administrator or his designated agent is hereby designated as the agent responsible for the administration, implementation and enforcement of this article.

(b) The agent shall establish street address numbers in accordance with guidelines established herein as follows:

(1) Street addresses shall be assigned by the agent to each lot on new final subdivision plats at the time of recordation. The agent shall then notify the respective developer of these addresses.

(2) The agent shall undertake a systematic renumbering program for streets within the county in accordance with the policies and a guideline established herein. In the interim, as building permit applications are filed for development on parcels along streets which have not yet been systematically renumbered, the agent shall determine and assign an appropriate street address number for such development prior to approval of such building permit.

(c) As street address numbers are determined and assigned by the agent as provided above, such number shall be recorded in an official street number index and atlas to be maintained by the agent and kept available for reference in the office of real estate assessment and in the office of the department of code compliance. No building permit shall be approved until a street address has been determined and assigned from the index map and atlas or, in the absence of a listing for that particular parcel in the official index, until such building permit application has been referred to the agent for a street number determination.

(d) The affected property owner or current occupant shall be notified by the agent in writing of any address change. The property owner shall be responsible for notifying the Postal Service, utility companies and other interested parties of any address change or new address.

(e) Within sixty (60) days after the receipt of written notification of change of address, the owner or occupant shall affix/display the assigned number as prescribed herein.
