Code Violation Leads – Building & Housing Code Violations (US cities)

Get building, housing and property code violations from the official open-data portals of New York City (HPD housing + DOB building), Chicago, Los Angeles, Austin, Seattle, Kansas City, New Orleans, Cincinnati, Orlando, Norfolk (VA), Montgomery County (MD), Cambridge (MA) and Reading (PA), all in one clean schema. Every row has the property address, ZIP, violation date, open / closed status, category, severity or class, description, inspector comments (where published), parcel / BBL, coordinates and a link to the source dataset.

Turn it on with Group by property to get a distressed-property list: one row per address with the number of violations, how many are still open, first and latest dates and the top problem categories, sorted by most violations.

Data comes from each city's public Socrata open-data API (no login, no scraping of protected portals). $1 per 1,000 rows. Filtered rows are free.

What it does

• 14 official datasets, choose any or "All cities". Every city's columns are mapped to the same fields, so you can combine cities in one spreadsheet or CRM.
• Date filters: violations from the last N days, or an exact date range. Newest first.
• Open violations only: skip anything the city marks closed, corrected, complied, resolved or dismissed.
• Severity / class / category filter: e.g. NYC HPD class C (immediately hazardous), vacant, infestation, elevator, structure, weeds.
• Keyword search over the full record: roof, mold, rodent, bed bugs, porch, fire escape, boiler, vacant...
• ZIP codes and address contains (street name) filters.
• Group by property with a minimum violation count (repeat-offender / distressed-property lists).
• Monitoring mode: onlyNew on a daily or weekly schedule returns only violations (or changed properties) you have not seen before.
• Optional raw field with every original column the city publishes.

Use cases

• Contractors and home services: roofers, plumbers, electricians, pest control, junk removal, lawn care, boiler and elevator companies – owners who are ordered to fix something now.
• Property managers and lenders: watch your own or your borrowers' buildings for new violations.
• Tenant advocates, journalists and researchers: worst buildings, hazardous-condition trends, response times.

FAQ

Does it include the owner's name and phone number? Only where the city publishes it in the violation dataset (most do not). The Actor never guesses or looks up contact details. Use the parcel / BBL number with your county assessor or skip-tracing tool.

Why are Chicago and New Orleans rows missing a ZIP? Those datasets do not publish ZIP codes; use addressContains or coordinates instead.

What does "status" mean? open / closed is normalized from the city's own status (statusRaw keeps the original). New Orleans does not publish a status. The Los Angeles dataset contains open cases only.

Why not every US city? Only cities that publish violations as current open data with an API are included. Tell us which city you need next.

Data licenses: each row links to its source dataset; data is published by the cities under their open-data terms. Not affiliated with any city.
