Reading Your First Lease: What to Look For
A lease is mostly plain English once you know what to look for: term and renewal, rent and fees, deposit deductions, maintenance duties, guest and break clauses, pet terms, and any attached addendums.
Leases are written by lawyers for landlords, not for you — which makes them feel intimidating, but they're not actually complicated once you know which sections matter. This is a clause-by-clause walkthrough of what a standard residential lease covers and what to look for in each section. Rules vary by state and even by city, so treat this as a reading guide, not legal advice — when a clause looks off, a quick search of your state's tenant rights (or a free tenant-rights hotline, common in many cities) settles it faster than guessing.
Term & renewal
How long the lease runs (usually 12 months) and what happens at the end — does it auto-renew month-to-month, convert to a new fixed term, or simply expire and require you to move out or re-sign?
Worth questioning: An auto-renewal clause with no notice window, or one that locks in a new fixed term automatically unless you give 60–90 days' notice you might not remember to give.
Rent & late fees
The exact rent amount, the due date, accepted payment methods, and the grace period before a payment counts as late.
Worth questioning: A grace period of zero days, or a late fee that's a large flat percentage of monthly rent rather than a modest fixed amount.
Security deposit & deductions
How much the deposit is, where it's held (some states require a separate account), and the specific list of what can be deducted — unpaid rent, damage beyond normal wear, cleaning if the unit's left a mess.
Worth questioning: Vague deduction language ('any damage, at landlord's discretion') instead of a specific list, or no stated timeline for returning what's left of the deposit.
Maintenance responsibilities
Who fixes what — landlords typically handle structural issues, appliances, and plumbing; tenants usually handle light bulbs, filters, and damage they caused.
Worth questioning: Language that shifts normal repair costs (a broken water heater, a failing appliance) onto the tenant instead of the landlord.
Guest & sublet policies
How long a guest can stay before they're considered an unauthorized occupant, and whether subletting or short-term renting is allowed at all.
Worth questioning: A guest policy so strict it effectively bans overnight visitors, or a flat no-sublet clause with no process for landlord-approved exceptions if your plans change.
Break clause & early termination
What it costs to leave before the lease ends — often a flat fee (one to two months' rent) plus notice, sometimes tied to finding a replacement tenant.
Worth questioning: No break clause at all, meaning you're on the hook for every remaining month of rent with zero exit option if life changes.
Pet clauses
Whether pets are allowed, any breed or weight restrictions, pet deposits or monthly pet rent, and what counts as pet damage at move-out.
Worth questioning: A pet deposit labeled non-refundable regardless of condition, which in some states isn't enforceable the way it's written — worth double-checking locally.
Addendums
Extra documents attached to the lease — move-in condition forms, parking agreements, HOA rules, mold or bedbug disclosures. These carry the same legal weight as the main lease.
Worth questioning: Addendums referenced but not actually attached or explained — sign nothing you haven't been handed and read in full.
The rule that saves the most arguments
If a landlord promises something verbally — "we'll fix that before you move in," "we won't enforce the no-pet clause for a small dog," "you can break the lease early if your job moves" — it isn't real until it's in writing. Ask for a signed addendum or, at minimum, get it over text or email before you sign. Verbal promises are the single most common source of first-apartment disputes, and they're also the easiest to prevent: write it down, or it doesn't exist.
Read it before you tour again, not after you sign
Ask for a copy of the lease before your final decision, not just at the signing table — a landlord unwilling to let you read it in advance is a signal on its own. Pair this page with the 32 questions to ask before signing so nothing in the lease surprises you, and use the apartment tour checklist to confirm the physical unit matches what the lease describes.
