One clear grade
A building's record, weighed and graded.
Blueprint pulls official violations, complaints and evictions, weighs each issue by severity, normalizes it per apartment where unit counts are published, then grades A to F against buildings of a similar size.
Among the best for its size.
- 1Read the record. Evictions, open code violations, complaints and enforcement, straight from public open data.
- 2Weigh by severity. An open, hazardous, unresolved issue counts far more than an old, closed one.
- 3Grade per apartment. Totals divided by homes, so a large building isn't punished just for being large.
