specified above, the Building Official may make or require any
other inspections of any construction work to ascertain compliance
with the provisions of this Code and other laws which are enforced
by the Building Department.
For the prupose of determining compliance with Sections 104(h),
105, and 502, the Building Official may inspect any structure.
G. Section 304. Add to Section 304 subsections (f) and
(9) to read:
(f) Compliance Survey Inspection. Upon receipt of a written
request for a compliance survey from the owner or agent and payment
of the fee specified in Section 303(d), the Building Official may
inspect an existing structure to ascertain its compliance with
the provisions of this Code and other applicable laws and
ordinances, and report his findings in writing to the ownex or
agent.
(9) Reinspections. A reinspection fee may be assessed for
each inspection or reinspection when such portion of work for
which inspection is called is not complete.
This subsection is not to be interpreted as requiring re-
inspection 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 it is apparent that
the inspector is being used to provide supervision of the work
rather than for the performance of his proper inspection duties.
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.
