Regardless of what your lease says, you have these rights in most states:
Habitable conditions. Working heat, hot water, plumbing, electricity, and a structurally safe building. If something breaks and the landlord won't fix it, you may have the right to withhold rent or "repair and deduct" (pay for the repair yourself and subtract it from rent). Check your state's specific rules.
Privacy. Your landlord must give advance notice before entering (usually 24-48 hours), except in genuine emergencies. They can't just show up.
Non-discrimination. Under the Fair Housing Act, landlords cannot discriminate based on race, color, religion, sex, national origin, disability, or familial status. Many states and cities add protections for sexual orientation, gender identity, and source of income.
Retaliation protection. Your landlord cannot raise your rent, reduce services, or evict you in retaliation for filing complaints, reporting code violations, or exercising your legal rights.
Security deposit return. Your landlord must return your deposit (minus legitimate, documented deductions) within a state-specific timeframe after you move out. Many states: 14-30 days. Some charge penalties if the landlord is late returning it.
