With the retaining wall apparently near completion, construction could begin soon with the appropriate permits. But according to Ms. Hart, contractors are already present and working at the site.

A search for building permits turned up no results, in a finding that was corroborated by a DOB spokesman.

Mr. Carrión said the contractors were conducting soil excavation to produce their own report of the site’s risks and foundational integrity. According to the DOB’s administrative code for geotechnical investigations, soil borings can be completed at a site without a DOB permit. 

Ms. Hart insisted that the community knows best about 3469 Cannon Place.

“FIPNA and the community board are interested in the long-term health of the neighborhood,” she said. “If we don’t think the building belongs here, we’re probably right.”
