In Residence Districts and Commercial Districts, the City Planning Commission may permit, in conjunction with a laboratory listed under Use Group VII,  modifications to bulk regulations, other than floor area ratio, provided that the following findings are met.

In order to grant the special permit, the Commission shall find that the proposed bulk modifications:

1. will not unduly affect the essential character or impair the future use and development of the surrounding area; and
2. will not unduly obstruct the access of light and air to adjoining properties or public streets.
