Use Claude to file tenant complaints from public records
Claude checked NYC building records, prepared 14 housing complaints, and submitted them for one tenant.
- What they did
- A tenant asked Claude code to behave like a tenant-side legal helper. It searched HPD violation listings and DOB records for the building BIN, pulled the city housing code, and tied each reported problem to the matching rule. From there, it wrote 311 complaints, sent them in a delayed sequence through a $4 VPS workflow, saved the case IDs in SQLite, and handled callback responses using photos uploaded by the user.
- How it went
- About 19 days afterward, the landlord was hit with a $2,800 fine, the building received a class C designation, and the rent hike was stopped. An inspector verified 14 violations, and the agent later surfaced two additional ones.
- Tips
- This setup took 48 hours to assemble and ran on a $4 VPS. Before anything is filed or answered, build in a clear approval step so you can review each complaint and any response.
