Property Violations Registry — Multi-City Code Enforcement

Official city building code-enforcement / property-violation records (NOT permits) from government open-data portals, normalized into one schema across cities. The records support property compliance review, municipal analysis, repair planning, and historical research.

Cities (all endpoints data-layer verified 2026-07-12)

City	Source dataset	Rows
Chicago, IL	Building Violations (`22u3-xenr`)	~2.0M
New York City, NY	HPD Housing Maintenance Code Violations (`wvxf-dwi5`)	~11M
San Francisco, CA	DBI Housing/Building Complaints (`gm2e-bten`)	~333k
Austin, TX	Code Enforcement Cases (`6wtj-zbtb`)	~83k

All are open Socrata SODA JSON endpoints — no login, no CAPTCHA.

Unified schema

{ violation_id, address, type, status, issued_date, description, city, state, raw }

raw preserves the full source row so no field is ever lost.

Input

cities — any of chicago, nyc, san_francisco, austin (default: Austin).
status — all or open (open/active only — the distress signal).
maxRecordsPerCity — cap per city, newest first (default: 100).

This public-record product is for property and regulatory research. It is not a consumer report and must not be used to determine an individual's eligibility for credit, insurance, employment, or housing.

Proof

node test_smoke.mjs pulls real rows from every city and asserts unified schema, correct city tagging, real content (id + address + date), and a working open-only filter. No account, no cost. Adding a city = one adapter in src/cities.js (endpoint + normalize + isOpen).
