Compared September 2026, against Brick Underground's own Brick Report product page and launch post.
Brick Underground's Brick Report is a free, one-time snapshot: you type in an NYC address and your email, and Brick Underground emails you back a report on that building — safety violations for pests, plumbing and heating, construction permits and date, energy ratings, and neighborhood context (demographics, crime, nearby schools, restaurants and grocery stores). By their own account it draws on New York City's Housing Preservation & Development, Department of Buildings, Department of Finance, 311 and Police Department data, plus FEMA, the U.S. Census Bureau and OpenStreetMap.
Nosy Neighbor answers the same question — what does the public record say about this NYC building — from dozens of city, state and federal sources, rendered in the browser the moment you ask, with no email required. A free account removes the daily limit on lookups; Pro ($9.99/mo, 7-day trial) adds deeds and mortgages, sales history, tax liens, property tax, comps, rental estimates, listing search, market alerts, and a REST/MCP API for calling it from your own code or an AI agent.
| Nosy Neighbor | The Brick Report | |
|---|---|---|
| Coverage | Dozens of city, state and federal sources per report: NYC PLUTO, DOB (violations, permits, jobs, safety, complaints, Certificates of Occupancy), ECB, HPD (violations, litigation, registration), ACRIS deeds & mortgages, DOF property tax and tax liens, 311, NYPD-reported crime, the Landmarks Preservation Commission, zoning, rent stabilization registration, energy benchmarking/Local Law 97, housing court, vacate orders, sidewalk and facade violations, lead water service lines, bedbug filings, E-designations and OER cleanup records, FEMA flood zones, NYC stormwater maps, FEMA claims history, the Census Bureau, EPA Superfund sites, zoned schools, subway and Citi Bike proximity, and current for-sale/rental listings. | Housing Preservation & Development, Department of Buildings, Department of Finance, 311, NYPD, FEMA, the U.S. Census Bureau and OpenStreetMap, per Brick Underground's own product page. |
| Freshness | Assembled from each agency's own system when you ask; a report is kept for up to seven days before it is fetched again, and every source names its own as-of date. | Not stated in Brick Underground's materials. |
| Cost | Free plan (Apartment Hunters): $0/mo, unlimited lookups. Pro: $9.99/mo, 7-day free trial. | Free. Brick Underground's launch post states: "Brick Underground is not currently charging for Brick Report." |
| What's free | The full property report, no email address required: lookups are already ad-supported and uncapped without an account. Signing up (still $0) ties that same unlimited access to your account instead of your IP address, with no card required. | The whole report, delivered by email after you submit your address. |
| API / AI-agent access | A REST API and an MCP server exposing six tools (property lookup, comps, rental estimates, listing search, listing-change alerts, mortgage rates) that Claude, ChatGPT and other tool-using agents can call directly, included with a Pro account. | Not offered, per Brick Underground's materials. |
| What it's for | A property research tool built to be used by a person AND an AI agent: one address report, plus comps, rental estimates, listing search and market alerts for anyone deciding whether to buy, rent, or hold. | A one-time building snapshot for someone casually checking out a listing, delivered by email rather than used interactively. |
Brick Underground's launch post and product page don't state how often the underlying data refreshes, whether the report covers all five boroughs equally, or whether an API or developer/agent integration exists beyond the address-lookup web form. Rather than guess, this page leaves those as unknown.
Neither product originates the underlying data — both assemble New York City's own public records into a report. The difference is in how much of the record each one covers, how current it is when you read it, and whether the answer can be reached by an AI agent as well as a person.
