Before you sign a lease, read the building.
Free, one building at a time: what the District assesses the lot at and what it assessed it at last year, what the Department of Buildings has permitted on it, and the zoning district the permits carry. All of it from the city's own records — nothing about any person, nothing scored.
Not the Rent Board, not legal advice, and never a consumer report — this describes a building, not a person, and no landlord can use it to look anyone up.
