Brix is a New York City building intelligence service that helps renters, residents, investors, lenders, researchers, and community organizations understand a property’s history before making decisions. Its address-based reports organize public records into practical information about building conditions, landlord history, and ownership. Users can review open hazardous violations and how long they have remained unresolved, heat and hot-water complaints, emergency repair history, inspections, permits, renovations, and trends over time. Reports also include building details, unit counts, neighborhood complaints, nearby construction, and comparisons with surrounding properties.

Brix’s ownership tools map current and past owners, related LLCs, managing agents, connected buildings, and broader landlord portfolios. For organizations, the company offers portfolio-level building intelligence, monitoring, diligence, and custom data, including analysis of violations and complaint patterns. Brix also publishes research on NYC housing, landlords, and building records, alongside educational resources on topics such as tenant rights, heat laws, and apartment conditions. The service is designed to make complex city data easier to explore, while noting that its building scores are estimates that should be independently verified.
