1. Application. Certificates for occupancy and compliance shall be applied for coincidentally with the application for a building permit and shall be issued within ten days after the lawful erection or alteration of the building is completed. A record of all certificates shall be kept on file in the office of the City Clerk and the Zoning Administrator, and copies shall be furnished on request to any person having a proprietary or tenancy interest in the building affected.
2. Land and Buildings. No land shall be occupied or used and no building, erected or structurally altered after the effective date of the Zoning Ordinance, shall be occupied or used in whole or in part for any purpose whatsoever, until a certificate is issued by the Zoning Administrator stating that the building and use comply with the provisions of this Zoning Ordinance and the building and health ordinances of the City.
3. Change of Use of Buildings. No change of use shall be made in any building or part thereof, erected or structurally altered after the effective date of the Zoning Ordinance, without a permit being issued therefor by the Zoning Administrator. No permit shall be issued to make a change unless the changes are in conformity with the provisions of this Zoning Ordinance.
4. Building Alterations. No permit for excavation for, or the erection or alteration of, any building shall be issued before the application has been made for a certificate of occupancy and compliance, and no building or premises shall be occupied until the certificate and permit are issued.
5. Nonconforming Uses. A certificate of occupancy shall be required of all nonconforming uses. Application for certificates of occupancy for nonconforming uses shall be filed with the City Clerk within twelve months from the effective date of the Zoning Ordinance, accompanied by affidavits of proof that such nonconforming use was not established in violation of Section 196.01 of this Zoning Ordinance. Nothing in this part shall prevent the continuance of a nonconforming use as authorized in Section 196.01, unless a discontinuance is necessary for the safety of life or property.
