Many tenants don't realize their landlord is breaking the law because they don't know what the law says. Here are seven illegal practices that happen far more often than they should.
1. Entering Without Notice
The law: Most states require 24-48 hours advance written notice before a landlord can enter your unit. The only exception is genuine emergencies (fire, flooding, gas leak).
What's not an emergency: "I was in the neighborhood." Showing the unit to buyers without scheduling. "Just checking on things."
What to do: Send a written reminder of the notice requirements. If it continues, file a complaint with your local housing authority.
2. Retaliating After Complaints
The law: Every state prohibits landlord retaliation. If you report code violations, request repairs, exercise lease rights, or join a tenant union, your landlord cannot raise your rent, reduce services, or try to evict you in response.
The presumption period: Most states presume retaliation if the landlord acts within 6-12 months of your protected activity.
What to do: Document the timeline carefully. If you reported violations on March 1 and got a rent increase notice on March 15, that pattern speaks for itself.
3. "Self-Help" Evictions
The law: In every state, your landlord cannot:
- Change the locks while you're living there
- Shut off utilities (water, gas, electricity)
- Remove your belongings from the unit
- Board up windows or doors
- Physically block you from entering
These actions are illegal even if you haven't paid rent, even if your lease has expired, and even if you've been told to leave.
What to do: Call the police immediately — this is often criminal conduct. You may also be entitled to significant damages in civil court.
4. Charging Excessive Security Deposits
The law:
- California: Max 2 months' rent (unfurnished), 3 months (furnished)
- New York: Max 1 month's rent
- Massachusetts: Max 1 month's rent
- New Jersey: Max 1.5 months' rent
What to do: Demand the excess back in writing. If refused, file in small claims court.
5. Keeping Deposits Without Itemized Deductions
The law: When a landlord keeps any portion of your security deposit, they must provide an itemized statement showing exactly what was deducted and why, along with receipts for repairs over a certain threshold.
Common violations:
- Keeping the entire deposit without explanation
- Vague deductions ("cleaning fee" without specifics)
- Deducting for normal wear and tear
- Missing the return deadline entirely
What to do: Send a demand letter. If ignored, file in small claims court. In many states, you can recover double or triple damages for bad-faith retention.
6. Discriminating in Housing
The law: The federal Fair Housing Act prohibits discrimination based on race, color, religion, national origin, sex, familial status (having children), and disability. Many states add sexual orientation, gender identity, source of income, and other categories.
Common violations:
- "No kids" policies (illegal under familial status protection)
- Refusing Section 8 vouchers (illegal in some states)
- Different terms for tenants of different races
- Refusing reasonable disability accommodations
- "English only" requirements
What to do: File a complaint with HUD (federal) or your state's fair housing agency. Document everything.
7. Failing to Maintain Habitable Conditions
The law: Every state requires landlords to maintain rental units in habitable condition — working plumbing, heat, electricity, structural integrity, and pest-free environment.
Common violations:
- Ignoring repair requests
- Taking months to fix urgent issues
- Blaming tenants for building-wide problems
- "You deal with it" responses to pest complaints
What to do: Put every request in writing. File a complaint with local code enforcement. In many states, you have "repair and deduct" or rent withholding options.
The Common Thread
Notice the pattern? Landlords get away with these violations because tenants don't know their rights. The single most powerful thing you can do as a renter is know the law that applies to you.
