How LeaseGuard reviews your lease.
LeaseGuard is an AI-powered residential lease analyzer for US renters. We scan uploaded lease agreements against every US state’s landlord-tenant laws, city-level rent-control ordinances, and a curated database of known illegal-clause patterns — in about 60 seconds.
Our mission
The average US renter loses an estimated $1,200 per year to unfair or illegal lease terms they don’t know how to spot. A lawyer review costs $300-500 and takes days. We built LeaseGuard so tenants can get an informed starting point in seconds, for free, before they sign.
Methodology
Every scan runs against three independent layers of legal-reference data.
- Layer i.51-state statute database
All 50 US states plus DC. Top-5 (CA / NY / TX / FL / IL) have 6-7 categories; all others have 5.
- Layer ii.147 illegal-clause patterns
Real-world bad-clause examples sourced from tenant-rights attorneys, court filings, and published case law.
- Layer iii.25+ city rent-control ordinances
Covers LA, SF, NYC, Seattle, Chicago, Boston, DC, and more major metros plus mid-size markets with rent control.
Both the free scan (Google Gemini 2.5 Flash-Lite) and the full paid report (Anthropic Claude Sonnet 4.6) receive state-specific legal context in their system prompt, so citations (e.g. “California Civil Code § 1954”) are grounded in our database rather than invented by the model.
Privacy
Uploads are encrypted in transit (TLS 1.3) and at rest (AES-256). We never sell your data. Lease text and the generated report are automatically deleted 30 days after upload.
Not legal advice
LeaseGuard is a software tool, not a law firm. The analysis is informational. For any binding legal decision, consult a licensed attorney in your state.
