5 Illegal Lease Clauses Hiding in Almost Every Rental Agreement (2026)
Most lease templates contain at least one clause that violates state law — and most tenants sign anyway. Here are the five most common illegal clauses, what makes them illegal, and exactly what to say when you find one.
Landlords reuse the same lease templates for years. Most were drafted by a non-lawyer, copied from another landlord, or downloaded from a forms site that hasn't been updated since 2018. The result: a huge percentage of leases in the wild contain at least one clause that's flat-out unenforceable — sometimes illegal — under state or federal law.
The catch? Tenants almost never know. They sign, the landlord enforces the bad clause, and the tenant pays. We've scanned thousands of real leases and these five clauses come up over and over.
1. "As-Is" Habitability Waivers
What it looks like: "Tenant accepts the Premises in ‘as-is’ condition. No warranty, express or implied, is provided by Landlord regarding the condition of the Premises."
Why it's a problem: Almost every state recognizes an implied warranty of habitability — a baseline guarantee that your unit will have working plumbing, heat, hot water, electrical systems, and be free of pests and structural hazards. You cannot waive this warranty in a lease, period. It exists by law, not by contract.
Even in states with weak tenant protection (Arkansas, Alabama), "as-is" clauses are challenged successfully when conditions affect health and safety. In strong-protection states (California, New York, Massachusetts, Washington), they're simply void.
What to say: "I'd like to remove the as-is language for any condition that materially affects health or safety. The implied warranty of habitability isn't something either of us can contract around — keeping it in just creates confusion."
2. Broad Indemnification of the Landlord's Own Negligence
What it looks like: "Tenant agrees to indemnify, defend, and hold Landlord harmless from any and all claims of every kind and nature."
Why it's a problem: "Indemnify" means you agree to pay for the landlord's legal liability. If the wording sweeps in claims caused by the landlord's own negligence — for example, a guest of yours slips on a broken stair the landlord refused to fix — you'd be on the hook for the lawsuit. Most states refuse to enforce these clauses as a matter of public policy. California Civil Code §1668 voids contracts that try to exempt anyone from liability for their own fraud or willful injury.
What to say: "I'm happy to indemnify you for damage caused by me or my guests. But the current language sweeps in your own negligence, which isn't enforceable anyway. Can we narrow it to claims arising directly from tenant's acts or omissions?"
3. Compounding or Daily Late Fees
What it looks like: "A late fee of $X per day shall accrue from the due date until the entire balance, including all previously assessed late fees, is paid in full."
Why it's a problem: Late fees in residential leases are governed by liquidated damages law — they have to be a reasonable estimate of the landlord's actual cost, not a punishment. A daily-accruing fee that compounds on previously-assessed fees is almost always struck down as an unlawful penalty. California courts typically find anything above 5% of monthly rent unreasonable. Texas caps it at 10% by statute. Most other states use a similar reasonableness test.
Watch out for sneakier wording too: "Late fees shall be assessed from the due date until paid in full" sounds compounding but might just be ongoing accrual of a one-time fee — that's usually legal but worth clarifying.
What to say: "Can we use a single flat late fee — say, $50 or 5% of rent, whichever is less — assessed once per late payment? That keeps it enforceable and keeps things predictable for both of us."
4. Termination Based on an Arrest (Not a Conviction)
What it looks like: "Any arrest of Tenant or Tenant's guests for a criminal offense shall constitute grounds for immediate termination of this Agreement."
Why it's a problem: An arrest is not a conviction. People are arrested every day for things they didn't do, were never charged with, or were later cleared of. Many cities now have Fair Chance Housing Ordinances (Los Angeles, San Francisco, Oakland, Berkeley, Seattle, Portland, Newark, Cook County IL, and growing) that explicitly prohibit landlords from taking adverse action based on arrests, dropped charges, or sealed/expunged records.
Even in jurisdictions without a Fair Chance ordinance, this clause runs into problems with the Fair Housing Act's disparate-impact doctrine — HUD has explicitly warned that blanket criminal-record screening can be discriminatory.
What to say: "I'd like to amend this so termination requires either a conviction or a court finding by a preponderance of the evidence — not just an arrest. Arrests aren't findings of guilt and using them this way may run into Fair Chance Housing rules in our city."
5. One-Sided Attorney Fees
What it looks like: "If Landlord employs an attorney to enforce any provision of this Agreement, Tenant shall pay all of Landlord's reasonable attorney's fees and costs."
Why it's a problem: This sounds reasonable until you read it carefully — the landlord recovers their legal fees if they sue you, but if you sue them and win, you get nothing. It creates an asymmetric threat that lets landlords pressure tenants into settling weak claims.
Many states have fee reciprocity statutes that automatically convert one-sided fee clauses into mutual ones. California Civil Code §1717 is the classic example — it makes any attorney fee provision mutual as a matter of law. So in CA, the clause is technically enforceable in both directions even if it's written one-sided. But that's a hidden technicality most tenants don't know about, and other states don't have the same protection.
What to say: "Can we make the attorney fees provision mutual — ‘the prevailing party in any legal action shall be entitled to reasonable attorney fees’? It's the standard in most modern leases and many states make it mutual by law anyway."
The bigger pattern
These five aren't cherry-picked. They show up because they're cheap to copy-paste and most tenants don't push back. The landlord doesn't lose anything by including them — even if the clauses are unenforceable, tenants who don't know better will still act as if they're bound, paying fees they don't owe and avoiding rights they actually have.
Before you sign anything, read every clause looking for these patterns. If your lease has two or more of them, that's a strong signal the landlord is using an outdated template and there are probably more issues you haven't spotted.
