When you sign a lease, you’re agreeing to a bunch of specific rules — how long you’ll stay, how much rent you’ll pay, what you can and can’t do in the unit. That stuff is real and binding. But here’s the thing a lot of people don’t know: a landlord cannot use a lease to take away rights the law already gives you.
Tenant rights organizations and state attorneys general consistently affirm this principle: tenants cannot sign away rights the law grants them, and landlords legally cannot enforce lease terms that violate state or local laws. So if something in your lease contradicts what your state says tenants are entitled to, that clause may not be enforceable — and a court may not back the landlord up on it. If you think a clause is illegal, don’t just ignore it on your own — talk to a tenant’s rights organization or legal aid service first.
Texas law, for example, explicitly lists things a lease cannot restrict a tenant’s right to do. Other states have similar protections baked in. The specific rights vary by state, so what applies in one place may not apply in another — but the core idea is the same everywhere: the law sets a floor, and no lease can go below it.
That said, a lease absolutely does bind you to things that are legal. If you agreed to a one-year lease, you’re on the hook for that year. If your lease says no pets, that’s enforceable. The Massachusetts Attorney General’s guide makes clear that when you sign, you’re locking in the terms of that agreement — and the type of lease you sign shapes what rights and responsibilities both sides have.
One more thing worth knowing: if a landlord tries to add new rules after you’ve already signed, you don’t have to automatically accept them. You can try to negotiate. And if you haven’t signed anything yet — that’s your window. Read it before you commit, and if something looks off, ask questions or push back before your name goes on the dotted line.
