Do I need a written sublease agreement for a student sublet?

Yes. A written sublease agreement is the only document that protects both parties if a dispute arises over the security deposit, property damage, or early move-out. A message thread is not sufficient — it lacks the structure to resolve ambiguous situations. A one-page written agreement is enough for most student sublets.

What should a student subletting agreement include?

A subletting agreement should include: full names of both parties, property address and unit, exact lease start and end dates, monthly rent and due date, security deposit amount and return conditions, list of included furnishings, utility arrangement, pet/smoking policy, and move-out condition requirements.

How much security deposit is standard for a student sublet?

One month's rent is the most common security deposit for student sublets. Some listers ask for half a month for stays under 8 weeks. The deposit should be returned within 14–30 days of move-out (state law governs the exact timeline). Deductions must be itemized in writing.

Student Subletting Agreement Checklist

4 min read · For listers and renters

A handshake deal or a DM agreement is not sufficient for a sublet — even between students. A written sublease agreement protects both the lister and the tenant, and it's the only document that can resolve a dispute over a security deposit or property damage. A single well-structured page is enough.

The required elements

Every sublease agreement must include:

Full legal names of both the lister (sublessor) and tenant (sublessee)
Property address and unit number
Exact lease start and end dates
Monthly rent amount and due date
Security deposit amount and return conditions
Contact information for both parties
Signatures and date

Furnishing and condition

If the sublet is furnished, attach an inventory list. This prevents disputes about what was present and in what condition when the tenant arrived.

List all furniture and appliances included by room
Note any existing damage for major items (scratch on desk, stain on couch)
Reference the move-in condition photos as part of the agreement

Do this regardless:Take timestamped photos of every room before the tenant's move-in date and share them with the tenant in writing. Both parties should acknowledge receipt. This documentation is what wins deposit disputes.

Utilities and services

List which utilities are included in rent (electric, gas, water, WiFi, trash)
Specify any caps (e.g., "electric usage above $75/month billed to tenant")
Clarify how internet service will be handled — transferred, shared account, or tenant sets up their own

Rules and restrictions

Smoking policy (inside the unit and on any outdoor space)
Pet policy (types, sizes, breed restrictions from the master lease)
Overnight guest limit or policy (check your master lease — many have limits)
Noise/quiet hours if the building has rules
Subletting restrictions — the tenant may not further sublet the unit

Security deposit terms

Specify the deposit amount, the account it will be held in, the timeline for return after move-out, and the conditions for any deductions. State law governs the maximum deposit and return timeline — look up your state's rules and reference them in the agreement. Most states require return within 14–30 days of move-out with an itemized deduction statement.

Move-out section

Move-out date and time (be precise — not just a date)
Required apartment condition for full deposit return (clean, no damage beyond normal wear)
Key return process
Deposit return timeline and method (Venmo, check, Zelle)

If something goes wrong

For deposit disputes: SublettingU's resolution team can review platform communication records. For property damage: document immediately with dated photos. For lease violations: serve written notice through the platform before escalating. For emergencies: the lister remains responsible to the landlord — provide your contact info so the tenant can reach you quickly.

Most sublet disputes are preventable. Good photos before move-in, a clear written agreement, and professional communication through the platform eliminate 90% of potential problems.
