Overview

Lease Trap Detector analyzes rental agreements to protect tenants from predatory practices. Upload your lease or paste the text, specify your location (for local law comparison), and get comprehensive analysis: RED flags for serious concerns (illegal clauses, landlord overreach, exploitative fees), YELLOW flags for questionable provisions (vague language, missing details), GREEN flags for good tenant protections. Each flag includes the actual clause text, plain-language explanation of the problem, legal status (illegal/unenforceable/exploitative), your rights under local law, and specific negotiation strategies. Also identifies missing protections, unusual fees, and provides negotiation scripts plus local tenant rights resources.

How to use it

  1. UPLOAD YOUR LEASE: Either upload PDF file or paste lease text directly into the text box.
  2. ENTER LOCATION: Type your city and state (e.g., 'San Francisco, CA' or 'Austin, TX') - this is critical for comparing to local housing laws.
  3. SELECT LEASE TYPE: Choose Apartment, House, Room rental, or Commercial to get relevant analysis.
  4. OPTIONAL CONCERNS: If you already noticed something fishy (like 'They want $500 cleaning fee' or 'Can landlord enter anytime?'), note it here for focused analysis.
  5. CLICK ANALYZE: Wait 30-60 seconds for comprehensive analysis.
  6. REVIEW COLOR-CODED FLAGS: RED = serious concerns/likely illegal, YELLOW = questionable/clarify with landlord, GREEN = good tenant protections.
  7. READ PLAIN LANGUAGE EXPLANATIONS: Each flag explains what the clause means in normal English, why it's problematic, what the law says, and what to negotiate.
  8. USE NEGOTIATION SCRIPTS: Copy the provided negotiation language to email or discuss with landlord.
  9. CHECK MISSING PROTECTIONS: See what important clauses should be in your lease but aren't.
  10. REVIEW UNUSUAL FEES: See which fees are higher than typical or potentially illegal.

Example

Scenario: You're a first-time renter in California looking at an apartment lease. The lease has a clause saying 'Landlord may enter apartment at any time for inspections' and charges a $400 non-refundable cleaning fee plus $200 'lease processing fee'. You're not sure if this is normal or legal.

What you do: Upload the lease PDF, enter 'Los Angeles, CA' as location, select 'Apartment' as lease type, note in concerns: 'Landlord entry anytime clause seems wrong, fees seem high'. Click Analyze Lease.

Result: RED FLAGS: (1) 'Landlord may enter at any time' - ILLEGAL in California. CA Civil Code 1954 requires 24-hour notice except emergencies. Your rights: Landlord MUST give 24-hour written notice and can only enter for specific reasons (repairs, showings with your permission, emergencies). Negotiation: 'This clause violates CA Civil Code 1954. Please revise to require 24-hour notice as required by law.' (2) $200 'lease processing fee' - LIKELY ILLEGAL. California law generally prohibits application fees over $55 and lease processing fees are often considered disguised application fees. Your rights: You can refuse to pay or negotiate removal. (3) $400 'non-refundable' cleaning fee - QUESTIONABLE. In California, cleaning fees must be itemized and can't exceed actual cleaning costs. 'Non-refundable' language is concerning. YELLOW FLAGS: (1) Security deposit amount not clearly stated - ask for specific dollar amount and confirm it doesn't exceed 2 months rent (CA limit for unfurnished). GREEN FLAGS: (1) Includes 60-day notice for rent increases - good, California requires this for increases over 10%. (2) Specifies habitability standards - protects your right to safe housing. MISSING PROTECTIONS: (1) No clause about landlord's duty to mitigate damages if you break lease early - California law requires this, should be explicit. NEGOTIATION SCRIPT: 'Hi [Landlord], I reviewed the lease and have concerns about three clauses that may violate California tenant law. [Details of violations]. Can we revise these sections to comply with state law? I'm happy to sign once these are corrected.'
