_1.jpeg)
Best-maintained = composite score 88/100 across 17 weighted factors: facade condition (25%), violations (20%), energy grade (15%), elevator uptime (12%), resident complaints (10%). This data-driven approach ensures objective rankings for Harlem buildings. It helps buyers and renters spot well-kept properties in neighborhoods like Central Harlem or East Harlem.
The scoring formula combines these factors: (Facadex0.25 + Violationsx0.20 + Energy Gradex0.15 + Elevator Uptimex0.12 + Resident Complaintsx0.10 +...) multiplied by 100. Each factor draws from public records like NYC DOB inspections and violation reports. This method highlights buildings with strong property upkeep and minimal issues.
Consider a brownstone in West Harlem scoring 92 points. Its facade earned 95/100 for clean brickwork and intact windows (95x0.25=23.75), violations were zero (100x0.20=20), energy grade hit 90 (90x0.15=13.5), elevator uptime was 98% where applicable (98x0.12=11.76), and complaints stayed low (92x0.10=9.2). The full calculation across all factors yields the high score, signaling top building quality.
