Apartment Lease Review Guide

What it is

A lease is a legal contract between landlord and tenant for the use of a residence. It runs for a fixed term (typically 12 months), at a specified rent, with rules about deposits, repairs, sublet, and termination.

Residential lease terms are heavily regulated by state and local law. Many provisions in a lease are illegal in some jurisdictions and enforceable in others. A clause that says "no exceptions" doesn't actually mean what it says if state law overrides it — but you'd have to fight to win.

The landlord drafted the lease. Their priorities are baked in. You have less leverage to negotiate than in commercial contexts, but you have more than you think — especially before you sign.

Common clauses to check

1. [ 01 ]

   Rent & escalators

   The base rent, payment schedule, late fees, and any escalators (rent increases) for renewal.

   What to look for

   • Monthly rent stated clearly, with payment due date and grace period.
   • Late fees within state-law limits (often 5–10% of monthly rent).
   • Renewal terms — fixed rent for renewal, market rate, or tied to inflation/index.

   Red flags

   • Late fees over 10% of monthly rent (likely unenforceable in many states, but invites a fight).
   • Acceleration clause — if you miss one payment, all remaining rent for the term is due immediately.
   • Automatic rent increase on renewal with no cap.
2. [ 02 ]

   Security deposit

   The deposit you pay up front, what it covers, and when you get it back.

   What to look for

   • Deposit amount — capped by state law (often 1–2 months of rent).
   • Conditions for return — clean apartment, no damage beyond normal wear and tear.
   • Timeline for return after move-out (usually 14–30 days; state-specific).
   • Itemized statement of any deductions.

   Red flags

   • Deposit exceeds state-law cap.
   • Vague "cleaning fee" or "preparation fee" deducted automatically.
   • No timeline for return — landlord can hold the deposit indefinitely.
3. [ 03 ]

   Term & automatic renewal

   How long the lease runs and what happens at the end. Automatic month-to-month is common; automatic full-year renewal is suspicious.

   What to look for

   • Fixed term clearly stated (start date, end date).
   • What happens at term end — month-to-month, automatic renewal, or fixed conversion.
   • Notice period to terminate at end (typically 30–60 days).

   Red flags

   • Automatic 12-month renewal unless you give 90+ days notice — easy to forget, hard to escape.
   • Renewal at "market rate" with no cap.
   • Notice required by certified mail with detailed format requirements.
4. [ 04 ]

   Early termination

   If you need to leave before the term ends — what does it cost?

   What to look for

   • Stated early termination fee (often 1–2 months of rent).
   • Notice period required (typically 30–60 days).
   • Carve-outs for legally-protected reasons (military deployment, domestic violence, uninhabitable conditions).

   Red flags

   • Early termination requires payment of all remaining rent for the term.
   • Early termination fee plus loss of security deposit.
   • No carve-out for legally-protected reasons.
5. [ 05 ]

   Subletting & assignment

   Whether you can rent your apartment to someone else (sublet) or transfer the lease (assignment). Often "with landlord consent."

   What to look for

   • Subletting allowed "with landlord's reasonable consent, not unreasonably withheld."
   • Process and timeline for landlord approval.
   • Whether the original tenant remains liable on a sublet.

   Red flags

   • Outright prohibition on subletting (some states deem this unenforceable).
   • Landlord consent at "sole discretion" (vs. "reasonable").
   • Original tenant fully liable on assignment (so you don't actually escape the lease).
6. [ 06 ]

   Maintenance & repairs

   Who fixes what. The landlord generally must keep the unit habitable; the tenant must keep it from getting worse.

   What to look for

   • Landlord obligation to maintain habitability (running water, heat, electric).
   • Timeline for repairs (24/48/72 hours for emergencies).
   • Tenant's right to "repair and deduct" if landlord fails (state-law right).
   • Definition of "normal wear and tear" excluded from tenant responsibility.

   Red flags

   • Tenant responsible for all repairs, including major systems.
   • No timeline for landlord response.
   • Tenant waives right to "repair and deduct" or to withhold rent for habitability issues — these waivers are unenforceable in many states.
7. [ 07 ]

   Joint and several liability

   Roommates: each tenant is fully liable for the entire rent, not just their share.

   What to look for

   • Whether roommates are jointly and severally liable (usually yes, even when not stated).
   • Whether one tenant's eviction triggers liability for others.
   • Process if a roommate moves out mid-term.

   Red flags

   • All tenants must remain on the lease for the full term — no replacement allowed.
   • Default by one roommate accelerates rent against all roommates.
8. [ 08 ]

   Eviction & default

   What constitutes default and what the landlord can do about it. Heavily state-regulated.

   What to look for

   • Definition of default (typically: non-payment, breach of lease terms).
   • Cure period before eviction (state-law typically 3–14 days).
   • Landlord's remedies — usually limited by state law to eviction process plus damages.
   • Tenant's right to notice and cure.

   Red flags

   • Lockout or self-help eviction without going through court — illegal in most states.
   • Acceleration of all rent on default.
   • Tenant waiver of statutory protections — often unenforceable but causes friction.

Other watchouts

• Pet policy — fee, deposit, and weight/breed restrictions.
• Smoking and short-term rental (Airbnb) prohibitions.
• Insurance requirements — many leases now require renter's insurance.
• Utilities — what's included in rent vs. paid separately.
• Parking — assigned, fee-based, or street.
• Move-in / move-out inspection — written checklist signed by both parties.
• Mandatory arbitration clause — increasingly common in residential leases.
• Holdover provisions — what happens if you stay past the term without renewing.

Frequently asked questions

Should I have a lawyer review my apartment lease?

For standard residential leases, most tenants sign without legal review. For high-rent units, complex roommate situations, or unusual terms (acceleration, mandatory arbitration, broad waivers), a 15-minute review by a tenants' rights attorney can save you from expensive surprises.

Is my apartment lease binding if it has illegal terms?

An illegal clause is usually void without invalidating the rest of the lease. The clause itself can't be enforced, but you'd have to assert that defense if the landlord tries. State and local tenant rights vary widely; check your jurisdiction.

Can my landlord raise my rent during the lease term?

Generally no, not within a fixed-term lease. The rent is set for the term. Increases happen at renewal — that's why automatic-renewal clauses with rent escalators matter so much.

What's a habitability requirement?

An implied warranty in most states that the unit is fit for human habitation — running water, heat, working plumbing, no major safety hazards. If the landlord breaches habitability, the tenant typically has remedies (rent withholding, repair-and-deduct, lease termination), even if the lease tries to waive them.

Can I sublet my apartment?

Depends on your lease and state law. Most leases require landlord consent, and most states require that consent be given on reasonable grounds. Outright prohibitions on subletting are unenforceable in some states.
