If, upon reinspection, the inspector determines a rental unit is unfit for occupancy by failing an inspection, the city shall provide the owner with written notice of nonissuance of a certificate of compliance. Such notice shall specify the date of the nonissuance determination, the rental unit address, the name of the owner, the name of the inspector and the specific reasons for the nonissuance determination. Failure to obtain a certificate of compliance will result in the nonissuance or revocation of the rental business license for that unit. The unit shall be posted unfit for occupancy. Tenants, if any, shall be required to vacate.
