A month to month lease agreement is a short document with a renewal mechanism, and most of its length is the same as any other tenancy agreement. What makes it different is four terms that carry all the weight, because in an arrangement that renews every month those are the only ones either side will ever invoke. This page is about writing those four so they do not need interpreting later.
The renewal, stated as a mechanism
Say plainly that the tenancy continues month to month until ended by notice, and say which day the month runs from. An agreement that says month to month without saying when the month begins produces an argument the first time notice is given mid-month: does the tenancy end on the last day of a calendar month, or a month from the day notice was served. Pick one and write the sentence.
Notice, both directions
How many days, from whom, in what form, and delivered where. State law sets the floor and in many states the agreement may lengthen it, sometimes only for one side. Include the address or email that notice must be sent to, because the second most common dispute after how much notice is whether notice reached anybody. A term naming the destination removes it entirely.
Rent changes
A month to month rent can usually be changed on notice, and the notice period for a change is often but not always the same as the notice to end. Write the number in, and write in how a change is communicated. Where local rent regulation applies it overrides what the agreement says, so a sentence acknowledging that is more honest than a clause that would be void.
What happens at the end
Move-out condition, the deposit return process and its deadline, and what happens to anything left behind. These are the same terms a fixed-term lease carries, and they matter more here because the end can arrive with a month's warning at any point in the year. A tenancy that can end in thirty days should not need a fortnight of negotiation about what happens when it does.
Questions people ask about month to month lease agreement
Does a month to month agreement need to be in writing?
Some states will recognise an oral month to month tenancy, but the four terms above are exactly the ones nobody remembers the same way. Writing them down is the point of the document.
Can the notice period differ for landlord and tenant?
In several states it already does by statute, usually requiring more from the landlord. The agreement can often lengthen notice but not shorten what the law requires.
What if the tenant stays after giving notice?
That is a holdover, and what happens next is governed by state law and by any holdover clause in the agreement. It is worth having a clause rather than discovering the default.
