1. Key points

  • The federal Fair Housing Act bans housing discrimination based on race, color, religion, sex, national origin, familial status and disability.
  • Security deposit limits, return deadlines and itemization rules are set by state and local law and vary widely.
  • Most states recognize a duty to keep rentals habitable (safe water, heat, working plumbing and electricity).
  • Notice rules for landlord entry and eviction also vary by state.

2. Document everything

Take dated photos at move-in and move-out, keep repair requests in writing, and save rent receipts. Local tenant unions and legal aid organizations can explain your city's rules.
