Where work is not commenced within one year
after the date of issuance of the permit, or work is shut down and
not restarted within one year, the permit shall thereby become void,
and operations shall not be restarted until a new permit has been
issued by the Commissioner of Public Works.
Where required by the Commissioner of Public
Works, and after foundations of any building or structure which is
being built abutting on the street line, or other boundary of public
land, are constructed, the owner shall file with the Commissioner
of Public Works a certificate made by a licensed surveyor to the effect
that such building is located upon the lot shown on the plans filed
with the Commissioner of Public Works. Such building or structure
shall not be built above the foundations until the required certificate
is filed and approved by the Commissioner of Public Works.
