(b)        when the Commissioner of Buildings has certified, in accordance with the provisions of Section 44-24 (Waiver of Requirements for All Zoning Lots Where Access Would Be Forbidden), that there is no way to arrange the spaces with access to the street to conform to the provisions of Section 44-43 (Location of Access to the Street);

(c)        for houses of worship, in accordance with the provisions of Section 44-25 (Waiver for Locally Oriented Houses of Worship).
