What it means
The City blurs the location of these inspections to protect privacy, so a file cannot be tied to one building. Several files nearby point to older rental buildings with maintenance problems in the area (mould, pests, heating, water infiltration).
What to do
Ask the seller whether the City ever inspected this building and for the reports and proof of repairs.
