Most of a lease renewal is ordinary, and reading it carefully is usually enough. But some addendum clauses cross a line from merely unfavorable to genuinely alarming, the kind you should question hard, negotiate out, or refuse to sign, and a handful may not even hold up in court. These are the ones that quietly strip your protections, shift the landlord’s risks onto you, or lock you in on lopsided terms. Spotting them before you re-sign is what keeps a routine renewal from becoming a year of regret.
This is the warning-signs companion to our plain guide on what each renewal clause means. Here we focus only on the red flags: ten clauses that should make you stop, and why they matter.
The short version
The clauses to treat as red flags are the ones that take away your rights or dump the landlord’s risk on you. Watch for a blanket clause letting the landlord raise rent anytime by any amount, a waiver of the right to a habitable home or of repairs, and broad waivers of your legal rights like the right to sue or to proper notice. Be wary of excessive or unlawful fees and penalties, a right for the landlord to enter without notice, and an automatic-renewal trap with a narrow cancellation window and steep holdover charges. Also flag one-sided attorney-fee or confession-of-judgment clauses, hold-harmless language making you liable for the landlord’s negligence, non-refundable or forfeitable deposits, and forced arbitration or retaliation terms. Several of these may be unenforceable where you live, so do not sign until you have questioned them and, ideally, gotten advice.

1. The landlord can raise rent anytime, by any amount
A renewal should state a specific new rent for a specific term. A red flag is a clause that lets the landlord increase the rent at will during the term, or by an unlimited or open-ended amount, rather than a set figure you agreed to. That turns your fixed-term lease into a moving target and removes the predictability that a lease is supposed to give you. If the addendum reserves a broad right to raise rent mid-term or on short notice, push for a fixed rent and term, and be cautious about signing something that leaves your housing cost open-ended.
2. A waiver of habitability or repairs
One of the most serious red flags is language where you supposedly accept the unit “as-is” and give up the right to a livable home or to necessary repairs. In most places, landlords have a baseline duty to keep a rental habitable that tenants cannot simply sign away, so a clause trying to waive it is both a warning sign and often unenforceable. Do not treat such a clause as normal. A landlord asking you to waive basic habitability or repair obligations is shifting a fundamental responsibility onto you, and that is exactly the kind of term to refuse and to raise with a tenant-rights resource.
3. Broad waivers of your legal rights
Be very cautious about clauses where you waive legal protections wholesale: the right to sue, the right to proper notice before eviction, the right to a jury, or statutory tenant protections. These waivers are designed to take away tools the law gives you, and depending on your state many of them do not hold up. The presence of sweeping “tenant waives all rights to” language is a signal that the lease is tilted heavily against you. You generally should not sign away core legal rights in a renewal, and a clause that asks you to is worth a hard stop and outside advice.
4. Excessive or unlawful fees and penalties
Watch for fees and penalties that seem punitive: late fees far above what your area allows, daily-compounding charges, large “administrative” or renewal fees, or penalties out of proportion to any actual harm. Many states cap late fees or require them to be reasonable, so an oversized penalty may be both a red flag and unenforceable. Add up what these clauses could cost you in a bad month. If the addendum stacks aggressive fees or sets penalties that look designed to trap rather than to cover a real cost, question each one and check it against your local limits before agreeing.
5. Entry without notice
Your home comes with a reasonable expectation of privacy, so a clause letting the landlord enter anytime without notice is a red flag. Most jurisdictions require advance notice, often around 24 hours, except in genuine emergencies, and a lease trying to grant unrestricted access conflicts with that and with your right to quiet enjoyment. A landlord who wants the power to walk in whenever they like is asking for more than the law generally allows. Insist on a proper notice requirement, and be wary of a renewal that quietly removes the notice you had before.
6. The automatic-renewal trap
Automatic renewal is not inherently bad, but it becomes a red flag when it is paired with a trap: the lease auto-renews for a long term unless you cancel within a narrow, easily-missed window, and stiff holdover penalties apply if you slip. That combination is engineered to lock you in. Look closely at how and when you must give notice to avoid renewing, and at what happens if you miss it. If the cancellation window is short and buried while the holdover penalty is steep, treat the whole clause with suspicion and pin down every deadline in writing.
7. One-sided attorney fees or a confession of judgment
Two related clauses deserve special alarm. A one-way attorney-fee clause makes you pay the landlord’s legal costs if there is a dispute, but not the reverse, which discourages you from ever enforcing your rights. Worse is a “confession of judgment,” where you pre-agree that the landlord can obtain a court judgment against you without a normal hearing. Confession-of-judgment clauses are banned in residential leases in many states precisely because they are so one-sided. Either clause is a strong red flag, and a confession of judgment in particular is something to refuse and to get legal advice about immediately.
8. A hold-harmless clause for the landlord’s own negligence
Look out for “hold harmless” or broad liability-waiver language that makes you responsible even when the landlord is at fault, for example if someone is hurt because the landlord failed to fix a known hazard. A clause that shields the landlord from the consequences of their own negligence is deeply lopsided, and in many places such waivers are limited or unenforceable. This is not a normal risk allocation; it is an attempt to make you bear liability that should sit with the property owner. Flag any hold-harmless clause and do not accept blanket responsibility for the landlord’s failures.
9. Non-refundable or forfeitable deposits
Be careful with clauses that label a deposit “non-refundable,” or that let the landlord keep your deposit for vague or minor reasons. A security deposit is generally meant to be returned minus legitimate, documented deductions, and calling it non-refundable, or setting up easy forfeiture, can run against deposit-protection laws in your state. This is a common way to quietly convert your refundable money into the landlord’s. Scrutinize any language about keeping, forfeiting, or not returning your deposit, and check it against your local deposit rules, because these clauses are frequently improper.
10. Forced arbitration, class waivers, or retaliation terms
Finally, watch for clauses that strip your ability to hold the landlord accountable: mandatory arbitration paired with a class-action waiver, terms letting the landlord terminate at will or evict without normal cause, or language penalizing you for complaining to a housing authority. These are designed to keep problems quiet and disputes out of your hands, and some, like punishing you for reporting code violations, may be illegal retaliation where you live. A renewal that tries to silence complaints or remove your avenues for recourse is waving a bright red flag, and it is worth serious pushback and outside advice.
What to do when you spot one
Finding a red flag does not always mean walking away, but it does mean stopping before you sign. Point to the specific clause and ask the landlord to remove or change it, in writing, and keep the correspondence. Check whether the clause is even enforceable where you live, since many of these are limited or void by state and local law, using a resource like USA.gov’s tenant rights guide to find local help. If a clause is serious, like a confession of judgment or a habitability waiver, get advice from a tenant attorney or your local housing agency before agreeing to anything. A landlord who will not remove an unlawful or grossly unfair term is telling you something useful about the tenancy ahead.
This article is general information, not legal advice, and it does not create an attorney-client relationship. Whether a clause is enforceable depends heavily on your state and local law and the specific facts, and some terms described here are void in some places and permitted in others, so consult a qualified attorney or your local housing or tenant-rights agency before signing or acting on a lease.
Frequently asked questions
Can a landlord put an illegal clause in a lease?
A landlord can write almost anything into a lease, but that does not make it enforceable. Many clauses, such as waivers of habitability, confessions of judgment, or fees above legal caps, are limited or void in various states regardless of your signature. Still, do not rely on a clause simply being unenforceable, since fighting it later is harder than refusing it now. Question and, ideally, remove problem terms before you sign.
What is a confession of judgment in a lease?
It is a clause where you agree in advance that the landlord can obtain a court judgment against you, often without the usual notice or hearing, if they claim you breached the lease. Because it waives basic due-process protections, it is banned in residential leases in many states. If you see one, treat it as a serious red flag and seek legal advice before signing anything that contains it.
Is a non-refundable security deposit legal?
Often not, at least not as described. Security deposits are generally meant to be returned minus legitimate, documented deductions, and many states regulate how they are handled and returned. Labeling a deposit “non-refundable,” or allowing easy forfeiture, can conflict with those rules. Look closely at any such clause, compare it to your local deposit laws, and be cautious about money the lease says you can never get back.
Do I have to sign a renewal with a clause I do not like?
No. A renewal is an offer, and you can ask for a clause to be changed or removed, decline the renewal, or give notice to move if the terms are unacceptable. A landlord is not required to agree, but you are not required to sign either. For clauses that are unfair or possibly unlawful, negotiating the change in writing, and getting advice, is far better than signing and hoping the term is unenforceable.
What should I do if a landlord refuses to remove a red-flag clause?
Take it seriously. A refusal to drop an unlawful or grossly one-sided term tells you about how the tenancy may go, and it is a reason to get advice before committing. Contact a tenant attorney or your local housing or tenant-rights agency to understand your options and whether the clause is even enforceable. Depending on the term and your situation, you may negotiate, decline, or look elsewhere, but do not simply sign past a serious red flag.
The bottom line
Most renewal clauses are ordinary, but a handful are genuine warning signs: open-ended rent increases, waivers of habitability or your legal rights, punitive fees, entry without notice, auto-renewal traps, one-sided legal clauses, hold-harmless language, forfeitable deposits, and terms that silence complaints. Several may be unenforceable where you live, but the smart move is to catch them before you sign, ask for them to be removed in writing, and get advice on the serious ones.
