If at any time after the issuance of such certificate
of occupancy it shall be determined in the findings of the Building
Inspector that the occupancy related to any plot or lot in the R-O
District shall deviate from the occupancy for which approval was initially
given, the Building Inspector shall give notice in writing to the
owner of the property in question, such notice shall set forth the
nature and extent of such deviations. Such notice shall be sent to
the owner of the property by registered mail. If the objectionable
deviations shall not be remedied by the owner within 30 days of such
notice, unless extended by the Board of Trustees, the certificate
of occupancy for the premises shall become void, without further or
additional notice.
