What should I look for in a lease before I sign?

A lease locks in where you live and what you owe for a year or more, yet most renters skim it and sign. You don't have to read it like a lawyer. About a dozen clauses cause almost all the trouble, and once you know them you can catch 90% of the problems in 15 minutes.

The rent and the late-fee math

Confirm the monthly rent, the due date, the grace period (often 3-5 days), and the late fee. Late fees that pile up daily, or that top roughly 10% of rent, are unenforceable in many states.

Security deposit — amount, return deadline, and itemization

Many states cap deposits at 1-2 months' rent and require the landlord to return them within 14-30 days with an itemized list of any deductions. A clause that lets the landlord keep the deposit for vague reasons like "cleaning" or "normal wear" is a red flag.

Term length, renewal, and how to give notice to leave

Check whether the lease auto-renews and what notice (often 30 or 60 days) you must give to end it. Auto-renewal traps are a common and expensive surprise.

Maintenance, repairs, and who pays for what

The lease should spell out how to request repairs and how fast the landlord must respond. Watch for clauses that push the cost of major repairs (HVAC, plumbing, structural) onto you — those are unenforceable in most states.

Entry rules — when the landlord can come in

Most states require 24-48 hours of written notice before the landlord enters, except in true emergencies. A clause letting the landlord enter "at any time" is a red flag.

Pets, guests, and roommate rules

Check pet deposits, weight and breed limits, guest-stay limits, and whether subletting is allowed. These often hide extra fees or eviction triggers.

Anything that takes away your right to sue

Mandatory arbitration clauses, jury waivers, and "hold harmless" clauses can quietly strip your legal rights. Some are unenforceable depending on your state, but know they're there before you sign.

Some clauses are illegal no matter what you signed

A clause saying you take the unit "as-is" or waive your right to a safe, livable home is void in essentially every state — the law reads that guarantee into residential leases. The same goes for "self-help eviction" language letting the landlord lock you out or shut off utilities without going through court. Signing doesn't make these enforceable.
