Subletting 101: What's Actually Allowed and What Isn't

Subletting comes up constantly for students and short-term renters, and the rules are less obvious than most people assume going in.

Most leases require landlord approval, even if the lease doesn't explicitly forbid subletting. "My lease doesn't say I can't" is not the same as "my lease says I can." Check the actual sublet clause, or ask directly — assuming it's fine because it isn't explicitly banned is the single most common mistake here.

An unauthorized sublet puts the original tenant at real risk, not just the subletter. If something goes wrong — damage, a subletter who stops paying, a lease violation — the original tenant, whose name is on the lease, is the one the landlord holds responsible. That's true even if the sublet felt informal and low-stakes at the time.

A proper sublet has its own written agreement. Rent amount, dates, what happens with the security deposit, and who's responsible for what — in writing, between the original tenant and the subletter, separate from (but consistent with) the original lease. A verbal handshake agreement is where most sublet disputes actually start.

Landlords often say yes if you ask properly. A landlord who finds out about an unauthorized sublet after the fact reacts very differently than one who's asked upfront with a specific subletter's name and dates. The approval process exists for a reason, but it's usually not actually hard to clear if you go through it honestly.

The practical version: read your specific sublet clause, ask your landlord directly rather than assuming, and get any agreement with your subletter in writing — every time, no exceptions for "it's just for the summer."
