DOB's Building Information System (BIS) is the traditional way to look up building permits, violations, and inspections. It's being replaced by DOB NOW for some functions, creating a split-system problem.
Data scope: BIS = DOB data only. RegWatch = DOB + HPD + DOF + ACRIS + DCP + 6 more.
Systems: BIS and DOB NOW are separate systems. RegWatch combines both.
Context: BIS shows violations without ECB hearing status. RegWatch links violations to ECB hearings and liens.
Monitoring: BIS is search-only. RegWatch offers portfolio monitoring with alerts.
Reports: BIS has no export. RegWatch generates professional PDFs.
BIS is the authoritative source for DOB data. RegWatch uses this data and adds the context of 10 more agencies, making it far more useful for comprehensive property research.
