(4) The request is made to avoid extreme financial hardship to the applicant, which hardship is not self-created.
B. Upon receipt of a request for expedited permit application review, the Building Commissioner shall review the request, together with the documentation supporting it, and render a proposed written determination. The proposed written determination shall then be forwarded to the Supervisor and the Councilperson having jurisdiction over the affected premises for comment from each. The Supervisor and the Councilperson shall have five business days to consider the request and proposed determination, and each may provide comment and/or recommendations to the Building Commissioner prior to the expiration of that time period.
C. In the event that the Supervisor and Councilperson make no comment or recommendation, the proposed determination shall become a final determination and shall become a part of the permanent file maintained by the Building Department.
