Lapse of Authorization or Special Permit Granted by the City Planning Commission Pursuant to the 1961 Zoning Resolution
(a) Except as otherwise provided in paragraphs (b), (c) or (d) of this Section, any authorization or special permit granted by the City Planning Commission under the provisions of the 1961 Zoning Resolution shall automatically lapse if substantial construction, in accordance with the plans for which such special permit or authorization was granted, has not been completed within four years from the effective date of such permit or authorization. Substantial construction shall mean, in the case of a new building or buildings, the substantial construction of at least one building. For the purposes of this paragraph (a), abutting buildings on a single zoning lot shall be considered to be one building.
(b) Any authorization or special permit for a site that is part of an urban renewal area or other government-sponsored or government-assisted project shall automatically lapse within four years from the date of the applicant's possession of the site, or sites, or the effective date of an authorization or special permit, whichever is later; or
(c) Upon a showing that a longer time period for substantial construction is required for a phased construction program of a multi-building complex, the Commission may, at the time of granting an authorization or special permit, extend the period set forth in paragraph (a) of this Section to a period not to exceed 10 years; or
(d) In the event judicial proceedings have been instituted to review the decision to grant any authorization or special permit, the lapse period set forth in paragraph (a), (b) or (c) of this Section, whichever is applicable, shall commence upon the date of entry of the final order in such proceedings, including appeals.
