What Is a Lease?
Plain-English breakdown of what a lease actually is, who's bound by it, and the jargon every renter should recognize.
7 min read
A lease is a binding contract between you (the tenant) and the property owner or their agent (the landlord) that gives you the legal right to live in a specific unit, in exchange for rent, for a specific length of time. Once both sides sign, neither can change the terms without the other's written agreement.
The two main lease types
- Fixed-term lease — usually 6 or 12 months. Rent is locked in for the whole term. You can't be evicted without cause, but you also can't walk away without consequences.
- Month-to-month — renews automatically every 30 days. More flexible, but rent can be raised and tenancy can be ended (by either side) with proper written notice — usually 30 days, sometimes 60.
Who is bound by the lease
Every adult living in the unit should be named on the lease. If you sign with a roommate under a "joint and several liability" clause (very common), the landlord can collect 100% of unpaid rent or damages from any one of you — not just the person who caused the problem.
The clauses you'll see in almost every lease
- Rent amount, due date, and late fees
- Security deposit — amount, where it's held, how it's returned
- Term — start date, end date, what happens at expiration
- Use of premises — residential only, no business operation, occupancy limits
- Maintenance & repairs — what's the landlord's responsibility, what's yours
- Entry by landlord — usually 24-hour notice required
- Pet policy, smoking policy, guest policy
- Termination & renewal — notice periods, early-exit fees, auto-renewal
- Default & eviction — what happens if you violate the lease
Example clauses you'll actually see
“Each Tenant signing this Lease shall be jointly and severally liable for the full performance of all obligations hereunder, including the payment of all Rent and damages, regardless of which Tenant caused the breach.”
What it means:If you sign with two roommates and one stops paying, the landlord can come after you for 100% of the rent. They don't have to chase the roommate who actually owes it.
Watch:Hard to remove, but you can sometimes negotiate "severally only" so each tenant is only liable for their share. Or pick roommates very carefully.
“If Tenant remains in possession of the Premises after the expiration of the Term without Landlord's written consent, Tenant shall pay Rent at one and one-half (1.5) times the monthly Rent for each day of holdover.”
What it means:Stay one day past the end date without a renewal in writing and rent jumps 50%. The clause is enforceable in most states.
Watch:Always have a signed renewal or move-out date confirmed in writing before the lease end date.
Renter jargon, decoded
- Addendum — a separate signed page added to the lease (pet addendum, parking addendum). Just as binding as the main lease.
- Concession — a discount the landlord gives you (e.g. "one month free"). Often clawed back if you break the lease early.
- Holdover tenant — someone who stays past the lease end. Usually triggers month-to-month at a higher "holdover rent" (often 1.5x–2x).
- Quiet enjoyment — your legal right to actually use and enjoy your home without unreasonable interference from the landlord.
- Implied warranty of habitability — the landlord's non-waivable duty to keep the unit livable (heat, water, structural safety, no infestation).
- Cure period — the window you get to fix a violation (e.g. pay overdue rent) before eviction can proceed.
Watch out for
A verbal promise from a leasing agent ("don't worry, we never charge that fee") is worth nothing once the lease is signed. If it's not in writing in the lease itself, it doesn't exist.
Try this
Read the lease the day before you plan to sign — never on the spot at the leasing office. Mark every clause you don't understand and bring questions back. A landlord who pressures you to sign immediately is telling you exactly who they are.
