Roommate Rights in District of Columbia
What District of Columbia law says about sharing a lease — who owes what, what happens when someone leaves, and how to protect yourself before problems start.
•Joint Liability
Are You Liable for Your Roommate's Rent?
In District of Columbia, all tenants on a joint lease are jointly and severally liable for the full rent amount. If one roommate stops paying, the landlord can pursue any or all remaining tenants for the entire balance.
Joint and several liability means the landlord does not care about your internal rent-splitting arrangement. If your roommate vanishes, you owe the full amount. This is the single most important thing to understand before sharing a lease. You can protect yourself with a written roommate agreement that spells out what happens if someone can't pay or wants to leave early.
•Subletting
Can You Sublet Your Room?
DC law generally allows subletting unless the lease prohibits it. If the lease requires landlord consent, the landlord must not unreasonably withhold it.
Even if your state allows subletting, your lease may prohibit it. Read the subletting clause in your lease before making plans. If the lease is silent, check your state's default rules. When in doubt, get written permission from your landlord — verbal agreements are hard to enforce.
•Adding a Roommate
How to Add Someone to Your Lease
Process
Requires landlord approval and a lease amendment. DC rent control may apply, limiting the landlord's ability to raise rent when adding occupants.
Never let someone move in without telling your landlord. Unauthorized occupants can be grounds for eviction in most states. Get the new person on the lease so everyone's rights and responsibilities are clear. The landlord may want to run a credit check — that's standard.
•Removing a Roommate
What Happens When a Roommate Wants to Leave
Process
Requires a lease amendment. The departing tenant is liable until formally released. In rent-controlled units, the remaining tenants retain the controlled rent.
The biggest mistake: assuming that moving out ends your lease obligations. In District of Columbia, a departing roommate typically stays liable for rent through the end of the lease unless the landlord signs a written release. Get everything in writing. If you are the one leaving, push for a formal lease amendment that releases you from further liability.
•Security Deposits
How Security Deposits Work with Roommates
One deposit per lease. DC requires return within 45 days. Landlord returns to the lease signers.
The landlord writes one check at the end of the lease — they do not split refunds among roommates. If one roommate caused damage, the landlord can still deduct from the full deposit. That means the roommate who did not cause the damage may lose their share. A roommate agreement can specify that the person who caused the damage is responsible for reimbursing the others.

•Roommate Agreements
What to Put in a Roommate Agreement
Your lease covers the relationship between tenants and the landlord. A roommate agreement covers the relationship between you and your roommates. It is a separate, private contract that is enforceable in court. Every shared living arrangement should have one.

- Shared spaces: Rules for common areas, cleaning schedules, guest policies
- Early departure: What happens if someone wants to leave before the lease ends — notice period, responsibility for finding a replacement
