StreetScore aggregates publicly available data from New York City government agencies to provide comprehensive background checks on any apartment for renters and buyers.
All information displayed on StreetScore is sourced directly from official NYC government databases and is already publicly available. StreetScore does not create, modify, or maintain this data — we aggregate and visualize it to make it more accessible. For corrections or disputes, please contact the relevant NYC agency directly.
NYC Housing Preservation & Development (HPD)
The official landlord registration database for buildings with 3+ residential units. Contains building IDs, landlord contact information, registration dates, and compliance status.
To request corrections: Contact HPD to update registration information or report non-registration.
NYC Housing Preservation & Development (HPD)
Comprehensive building data for properties under HPD oversight. Includes structural attributes, building classification, unit counts, and address information.
To request corrections: Contact HPD to correct building attributes or report errors in building records.
NYC Housing Preservation & Development (HPD)
Complete violation history issued by HPD inspectors. Violations are classified by severity (Class A/B/C), with inspection dates, detailed descriptions, and current status.
To request corrections: If a violation shows as open but has been corrected, contact HPD to schedule a re-inspection or submit certification of correction.
NYC Department of Buildings (DOB)
Construction and renovation permits filed with DOB. Contains permit type, work descriptions, filing dates, and owner/applicant information.
To request corrections: Contact DOB to correct permit records or report unpermitted work.
NYC Department of City Planning (DCP)
NYC's most comprehensive property dataset. Contains tax lot data, zoning information, FAR (Floor Area Ratio), coordinates, year built, landmark status, and assessed values.
To request corrections: PLUTO data is compiled from multiple city agencies. Contact the relevant agency for corrections (DOF for assessments, DOB for building data, etc.).
NYC Department of Finance (DOF)
Historical property sales data including sale prices, dates, buyer/seller information, and property type. Enables tracking of building ownership changes and market trends.
To request corrections: Contact NYC Department of Finance to report errors in property sales records.
NYC 311
Real-time complaint data from NYC's non-emergency hotline. Residents report heat/hot water outages, noise complaints, rodents, sanitation issues, and building conditions. This powers our Live Pulse feature showing quality of life issues at any address.
To request corrections: 311 complaints are submitted by residents. If you see inaccurate data, you can submit a new complaint with corrected information.
Google Places API
Real-time walkability analysis powered by Google Places. We score every building's proximity to parks, bodegas/groceries, restaurants, and schools within a 10-minute walk. Each category contributes to an overall Neighborhood Amenities Score that helps you understand location quality.
To request corrections: Business information is sourced from Google. To update business listings, claim your business on Google Business Profile.
User Submitted
Historical rent prices crowd-sourced from public listings. Track how rents have changed over time for any building, including current and past listings, price changes, and market trends.
To request corrections: This data is aggregated from public listings. Contact us if you notice inaccuracies.
U.S. Environmental Protection Agency
Federal drinking water quality data from the EPA's Safe Drinking Water Information System (SDWIS). NYC's water system (PWSID: NY7003493) serves all 5 boroughs from the same Catskill/Delaware watershed. Since all NYC buildings share the same water source, we verified NYC's compliance status and hardcoded it rather than making live API calls.
To request corrections: Water quality data is maintained by the EPA. For questions about NYC water specifically, contact NYC DEP.
Federal Communications Commission
Official broadband availability data from the FCC's Broadband Data Collection (BDC). ISPs are required by law to report service availability at every address. We use this to determine if fiber, cable, or DSL is available at your building, along with max advertised speeds and provider competition.
To request corrections: Broadband availability data is reported by ISPs. If you believe your building's data is incorrect, you can file a challenge with the FCC.
Ookla (Speedtest.net)
Real-world internet speed measurements from millions of Speedtest.net users. Unlike FCC data which shows advertised speeds, Ookla data shows actual measured download/upload speeds and latency. We match each building to the nearest speed test tile (~600m) to estimate real-world performance.
To request corrections: Speed test data is crowd-sourced from real users. Run your own speed test at speedtest.net to contribute.
StreetScore downloads, processes, and combines these datasets to power comprehensive apartment background checks. Here's what we do:
We link records across datasets using BBL (Borough-Block-Lot) and BIN (Building Identification Number) to create comprehensive building profiles.
We calculate risk scores, rent stabilization likelihood, landlord report cards, neighborhood amenities scores (parks, bodegas, restaurants, schools), and 25+ other intelligence metrics from the raw data.
We parse violation descriptions to detect pest issues, heat failures, toxic materials, and other specific conditions.
We identify recurring problems, construction harassment patterns, and shadow landlord portfolios that aren't obvious from single records.
