Listing + screening AI that survives a fair-housing audit
Listing copy that hints at a preferred tenant, a chatbot that steers by neighborhood demographics, a screening model with disparate impact — each is a Fair Housing Act case. EvalGuard gates every output on fair-housing scorers and keeps the decision trail HUD-style complaints demand.

What ships today
Honest posture, not roadmap promises
Every checked item is in production today. In-progress items are flagged explicitly — no overclaiming, no vapor.
Built for buyer reality
Real estate AI use cases we ship for
Listing-copy generation at portfolio scale
AI writes hundreds of listing descriptions a day. Phrases like 'perfect for young professionals' or 'family-friendly block' read as preference signals under the FHA — every description needs a fair-housing gate, not a spot check.
EvalGuard features
- Steering-language guardrails block preference and demographic signals
- Bias scorers screen copy against protected-class proxy phrases
- Output guardrails strip preference language so descriptions stay amenity-first
- Audit log preserves every generated description for complaint defense
Tenant + buyer screening assistance
AI summarizes applications and flags risk factors. Any systematic disparity across protected classes is an ECOA/FHA exposure — screening needs disparity testing before deploy and a per-decision trail after.
EvalGuard features
- Bias scorers gate screening outputs; red-team packs run counterfactual disparity probes pre-deploy
- Applicant-PII firewall redacts identifiers before third-party model calls
- Tamper-evident audit log ties each recommendation to model + prompt version
- Evidence-bundle export packages the testing file for your counsel
Property-inquiry chatbot
Prospects ask about neighborhoods, schools, and availability. Answering 'is this a safe area?' with demographic composition is textbook steering — the bot must redirect to objective data sources every time.
EvalGuard features
- Steering guardrails block demographic-composition answers so the bot falls back to objective data sources
- Prompt-injection defense: 300+ attack plugins cover baiting the bot into steering language
- Faithfulness scorer grounds availability answers in live listing data
- Per-route rate limits contain scraping of portfolio availability
Lease + document Q&A for residents
Residents query an assistant about lease terms, fees, and notices. A hallucinated fee or invented clause becomes a landlord-tenant dispute — answers must quote the actual executed lease.
EvalGuard features
- Citation scorer requires lease-document grounding for every answer
- Hallucination gate blocks answers that drift from the executed terms
- Per-project BYOK isolation separates each property-management client
- Gateway cost ledger attributes spend per property, with per-tenant daily budget caps
