§ 35-a. Limitation of time for revocation of permit. An action or proceeding to revoke a building permit on the ground that the building erected pursuant thereto stands wholly or partly within the bed of any street or highway shown on the official map or plan of a city must be commenced within fifteen years from the time of the issuance of such permit; but if at the time this act takes effect more than fourteen years have elapsed since the time of the issuance of the permit, an action or proceeding to revoke the permit on such ground must be commenced within one year from the time this act takes effect. If no action or proceeding is commenced within the time limited, the permit shall be deemed as valid as if it had been issued pursuant to the provisions of section thirty-five of this chapter.
