DeBlasio can't get DOB letter for his house

From DNA Info:

In the past five months, Mayor Bill de Blasio has twice applied for a DOB document that would verify that the century-old two-family Park Slope rowhouse that he and his wife own but rent out is being used legally. Both times the DOB rejected the de Blasios’ application because it lacked the proper paperwork.

The de Blasios seek what’s known as a "letter of no objection," which serves as a substitute for a certificate of occupancy for homes built prior to 1938. Before that year, certificates of occupancy weren’t issued.

When a property owner puts in an LNO application, the DOB will review the paperwork and, if it meets all requirements, will confirm that a property is being used the right way.

The Buildings Department wouldn’t specify the reason for the de Blasios’ rejection, other than to say that some documents were missing in both applications.
