In the District of Columbia, about 189,800 of 324,500 occupied homes, or 58.5 percent, are rented, according to the U.S. Census Bureau’s 2020 to 2024 American Community Survey (Homzora Washington, D.C. dataset, Table B25003). The median gross rent is $1,954 a month (Homzora Washington, D.C. dataset, Table B25064). Many renters share costs with roommates or need to leave before a lease ends, which makes subletting and roommate rules a practical question for a large number of households.
This guide explains subletting, lease assignment, and adding roommates in Washington, D.C. under District of Columbia law and any local rules, how to ask your landlord the right way, and what to put in writing.
Quick answers
- Sublet rent: a sublessor may not charge a subtenant more than the sublessor pays, according to a D.C. appeals decision (D.C. Office of the Tenant Advocate, Court of Appeals decisions on subletting).
- Removing a subtenant: only through court process (D.C. Office of the Tenant Advocate, Court of Appeals decisions on subletting).
What D.C. courts have said
The D.C. Office of the Tenant Advocate summarizes appeals decisions holding that a sublessor was prohibited from charging subtenants more rent than she paid her landlord, and that a tenant could not evict a subtenant except through court process (D.C. Office of the Tenant Advocate, Court of Appeals decisions on subletting). Check your lease for consent requirements, and get approval in writing.
Short term rentals in D.C.
District short term rentals are tied to the host’s primary residence, and vacation rentals cannot exceed 90 nights in a calendar year (D.C. DLCP, Short term rental guide).
Sharing rent in Washington, D.C.
As an illustration, splitting the median gross rent of $1,954 a month in the District of Columbia between two people would be about $977 each (Homzora Washington, D.C. dataset, Table B25064). Splitting costs only works if everyone pays on time, so put the arrangement in writing.

Sublet, assignment, or new roommate?
- Sublet: you rent all or part of your unit to someone else while you remain the tenant and stay responsible to the landlord.
- Assignment: you transfer the lease to someone else, who takes over as tenant; whether you are released depends on the agreement.
- Adding a roommate: another person moves in, either as a co tenant on the lease or as an occupant.
Each has different consequences for who owes rent and who can be evicted, so be clear about which one you are asking the landlord to approve.
How to ask your landlord
- Read your lease for any clause on subletting, assignment, guests, or occupants.
- Write to the landlord with the proposed person’s name, the dates, and whether you will remain on the lease.
- Offer to have the person complete the landlord’s application and screening.
- Ask the landlord to confirm approval in writing before anyone moves in.
- Keep copies of every message and the final approval.
A sample sublet request
Date: 2026. To: [landlord]. Re: Request to sublet [address, unit]. I am requesting permission to sublet my unit to [name] from [start date] to [end date]. I will remain responsible under the lease during this period. [Name] can complete your application and screening. Please let me know in writing whether you approve or what else you need. Sincerely, [name, phone].
What a written sublease should cover
- The names of everyone involved and the unit address.
- The start and end dates.
- The rent the subtenant pays, when, and to whom.
- How the security deposit will be handled.
- Who pays utilities and how.
- The rules from the main lease that the subtenant must follow.
- What happens if the subtenant damages the unit or stops paying.
Roommate agreements
Even when everyone is on the lease, a written roommate agreement prevents most disputes. Cover how rent and utilities are split, who pays the landlord, quiet hours, guests, cleaning, shared purchases, how the deposit will be divided, and what happens if one person wants to leave early. If all roommates sign the lease, each may be responsible for the full rent if another stops paying.
Risks of an unapproved sublet
Subletting without required permission can be a lease violation that leads to an eviction notice, and you may still owe rent if the subtenant does not pay. A subtenant who was never approved can also be in a difficult position if the landlord objects. Getting written approval first protects everyone.
Build your evidence file
Landlord and tenant disputes are usually decided by documents. Keep these together from the day you sign:
- The signed lease, every addendum, and every renewal.
- Receipts or bank records for the deposit and each rent payment.
- Dated photos and video of every room at move in and move out.
- Copies of every repair request and the landlord’s replies.
- Every notice you send or receive, with proof of delivery.
Keep copies somewhere other than your phone, such as an email to yourself, so they survive a lost device.
Screening a subtenant or roommate
- Meet in person or by video and confirm identity.
- Ask for references from past landlords or roommates.
- Confirm income or savings sufficient to pay their share.
- Agree on house rules before signing anything.
- Never hand over keys before the landlord approves and the agreement is signed.
Guests versus occupants
Most leases allow short visits by guests but limit how long someone can stay before they count as an occupant. If a partner, friend, or relative starts staying most nights, check your lease and ask the landlord how to add them properly rather than waiting for a complaint.
When a roommate moves out
If a roommate leaves before the lease ends, the remaining tenants may be responsible for the full rent. Talk early about whether to find a replacement, how the departing roommate’s share of the deposit will be handled, and whether the landlord must approve the newcomer. Put any agreement in writing.
Splitting the security deposit
Landlords usually return a single deposit for the unit. Agree in writing who will receive it, how it will be divided, and how damage caused by one roommate will be charged. When a roommate leaves mid lease, the incoming person often pays the departing person for their share, so document that payment too.
Summer and student sublets
Short summer sublets are common near colleges, and they are also a common setting for scams. Verify that the person subletting actually lives in the unit, confirm the landlord has approved, and avoid paying by wire, gift card, or cryptocurrency.
Paying rent in a shared household
Decide whether each person pays the landlord directly or one person collects and pays the full rent. If one person collects, use a payment method that leaves a record and keep receipts. Set a due date a few days before rent is due to the landlord so late payments from one roommate do not make everyone late.
Utilities and shared accounts
When utilities are in one person’s name, that person is responsible to the provider if others do not pay. Spread accounts across roommates or agree in writing how bills will be split and when each person pays. Close or transfer accounts promptly when someone moves out.
Insurance for roommates and subtenants
Many renters insurance policies do not automatically cover unrelated roommates or subtenants. Ask your insurer how it treats other people living in your unit, and encourage each person to carry their own policy for their belongings and liability.
