Notice to end a month-to-month tenancy
A D.C. tenant may end a month-to-month tenancy with 30 days' written notice that expires on the first of a month, but a housing provider can end one only for a cause listed in the Rental Housing Act, such as 90 days' notice for an owner move-in (D.C. Code §§ 42-3505.54(a), 42-3202(b), 42-3505.01).
Just cause required: a D.C. housing provider cannot end a residential tenancy by notice alone, even after the lease expires, while the tenant pays rent. Notice depends on the ground: 30 days to cure a lease violation; 30 days after a court finds an illegal act (10 days for certain violent crimes in cases filed after Dec. 31, 2025); 90 days for owner move-in or sale to a buyer who will live there; 120 days for substantial rehabilitation and similar; 180 days for demolition or discontinuing housing use. Notices other than for nonpayment must also be filed with the Rent Administrator. Tenant: 30 days' written notice, expiring on the first day of the first month at least 30 days after the notice.

With 60 days' notice delivered on November 1, 2026, the earliest effective date the form accepts is December 31, 2026, and the example moves it to the first day of a month on or after that date. District of Columbia's rule above sets different terms in some situations, so set the form's notice period to the one that fits your tenancy.
City and county rules can be stricter than state law, and your lease can require more than the statute does. Use whichever rule gives the tenant more time or protection.
