In cases where repairs are made to an existing structure and the footprint of the structure or structures is not altered, the applicant need only obtain a building permit. Building permits for such repairs shall be issued without review and shall not be subject to Code provisions regarding setbacks, height restrictions, parking requirements, green space, stormwater retention or impervious surface ratio requirements. In the event that the footprint of one or more buildings is proposed for modification, the owners shall submit a post-disaster site plan which must be approved prior to issuance of a building permit. Post-disaster site plans shall not be required to demonstrate compliance with, nor shall the owners be required to obtain a variance from, Code provisions relating to height, setbacks, parking, green space and impervious surface ratios. It is not the intention of this section to relieve any property owners from reconstructing in a manner which conforms to applicable City standards to the extent feasible.
