ListProse

Fair Housing risk scanning, embeddable in one script tag

An 84-rule engine that reads a listing description and flags the phrasing that creates Fair Housing exposure — with a suggested fix for every flag. Built for the teams already shipping products to US real estate agents.

84-rule engine · federal + state notes (CA/NY/NJ) Risk-reduction layer — not legal advice JSON in / JSON out White-label ready

What the module does

Integration

We wire it in with you during the pilot — no rewrite on your side. Two shapes, both built on the same rule set:

Typical pilot setup is about an hour of our time; we ship the snippet or endpoint, you mount it, and we tune the flag presentation together. Rule set, severity levels, and the "not legal advice" line all come from us.

Questions teams ask

Is this legal advice?

No. This is a risk-reduction tool that flags language patterns associated with Fair Housing exposure. It is not legal advice and it does not certify compliance with any law or regulator. Always have your own counsel review anything you ship to agents.

What is the rule set based on?

Published federal Fair Housing protected classes plus three practical buckets we see in listing copy: steering, income/status, and overstated marketing clichés. State notes for California, New York, and New Jersey are included as plain-language pointers to the official texts. The rule count and version are exposed in every response.

Can we white-label it?

Yes — that's the point. Your name, your colors, your subdomain. We don't put our brand in your agent's workflow.

What happens to the listing text?

Embedded scans run in the browser. Server-side scans process the text and return flags; we keep an audit log of length and IP prefix only, not the listing content. See Privacy.

Method & evidence

We publish how the engine is tested: 12 adversarial scenarios run on every release, and the rule count is verified against the shipped rule file. See Methodology & Evidence. The same engine powers our public free checker — try it on your own copy before you talk to us.
