b. An additional Section 307 is hereby added to said code as
follows
"Sec 307 Reinspections A reinspection fee may be
assessed for each inspection or reinspection when a
portion of work for which inspection is called is not
complete or when corrections called for are not made
"This section is not to be interpreted as requiring
reinspection fees the first time a job is rejected
for failure to comply with the requirements of this
Code, but as controlling the practice of calling for
inspections before the job is ready for such inspection
or reinspection
"Reinspection fees may be assessed when the permit
card is not properly posted on the work site, the
approved plans are not readily available to the
inspector, for failure to provide access on the date
for which inspection is requested, or for deviating
from plans requiring the approval of the Building
Official
"To obtain a reinspection the applicant shall file an
application therefor in writing upon a form furnished
for that purpose, and pay the reinspection fee estab-
lished by this ordinance In instances where rein-
spection fees have been assessed no additional in-
spection of the work will be performed until the
required fees have been paid "
