Where to start

The short version

Sometimes life means leaving a home before the lease ends. Done openly and in writing, subletting can work well for everyone.

Read your lease and ask the owner for permission in writing before you advertise or hand over keys.

In a sublet, the original tenant usually stays responsible. Write a simple sublease and do a condition report with photos.

Choose a subtenant carefully and fairly, stay reachable, and talk problems through early and kindly.

Subletting rules differ a great deal from place to place, so we’d gently encourage a quick look at the rules where your home is. If you ever have questions, we would love to help.

Four simple rules

  1. 1
    Ask first, in writing

    Most leases require the owner’s written permission before subletting or assigning. Ask before you advertise.

  2. 2
    Know who is responsible

    In a sublet, the original tenant usually stays responsible for rent and the home under the lease.

  3. 3
    Put it all in writing

    A written sublease spells out dates, rent, house rules, utilities and the condition of the home.

  4. 4
    Choose with care

    Meet the person, check references and follow fair housing rules when choosing a subtenant.

If a sublet runs into trouble

  1. Take a breath. Most sublet problems can be worked out with a calm conversation.
  2. Talk with the subtenant kindly about the issue, whether it is late rent, noise or damage.
  3. Look at the written sublease and the original lease to see what each person agreed to.
  4. Keep the owner or manager informed, especially if rent is late or the home is at risk.
  5. Write down what happened, with dates and photos, and keep copies of every message.
  6. If you can’t resolve it, a local tenant association, mediation service or attorney can help.

You did exactly the right thing.

Sublet or assignment?

In a sublet, the original tenant usually keeps the lease and rents to someone else for a time, staying responsible to the owner.

In an assignment, the original tenant usually transfers the lease to someone new, who takes over the lease going forward, if the owner agrees.

Roommates come first. They will live with your subtenant every day.

For owners: when a sublet request comes in

  1. Respond promptly and in writing, with clear reasons if you say no.
  2. Follow the lease and local rules, which in some places limit when consent can be refused.
  3. Use the same fair screening standards you use for any applicant.
  4. Confirm in writing who is responsible for rent, damage and the deposit during the sublet.
  5. Write down what was requested, what was decided and when.

A simple, written sublet request form makes the process fair for everyone.
