FYI. This is how this will play out...

Temporary certificate of occupancy (TCO)
A temporary certificate of occupancy grants residents and building owners all of the same rights as a certificate of occupancy, however it is only for a temporary period of time. In New York City, TCOs are usually active for 90 days from the date of issue, after which they expire. It is perfectly legal, and not uncommon in the given situation, for a building owner to re-apply for a TCO, following all the steps and inspections required originally, in order to hypothetically extend their TCO for another period of time.
Temporary certificate of occupancies are generally sought after and acquired when a building is still under minor construction, but there is a certain section or number of floors that are deemed to be habitable, and, upon issuance of TCO, can legally be occupied or sold.
