In the event off street parking facilities required to be provided under this code, or any prior provision thereof, in connection with any structure or use are at any time not maintained for automobile parking purposes to the extent required, the city building official shall revoke and cancel the certificate of occupancy theretofore issued for such structure after holding a hearing upon at least ten (10) days' written notice of the time, place, and purpose of the hearing having been mailed to the owner or other person occupying the same as shown on the records of the city clerk or the division of building and planning; provided, however, if it appears that the failure to maintain such required parking was reasonably beyond the control of the person required to maintain the same, no certificate of occupancy shall be revoked until such person shall have had at least ninety (90) days to reestablish the minimum required parking. In the event any certificate of occupancy is revoked, the premises covered thereby shall not be occupied or used for any purpose until a new certificate of occupancy has been issued. (1962 Code § 10-749)
