Can a landlord refuse to prorate rent?
Generally, yes — a landlord can decline to prorate. No Maryland statute requires proration for a mid-month move-in. But there's more to it: the lease controls, move-out works differently, and one rule genuinely binds landlords either way.
Move-in: proration is a lease term, not a legal right
Maryland law doesn't require landlords to prorate rent when a lease starts mid-month. A landlord can require a full month's rent for a partial month — though in a competitive market almost nobody does, because applicants simply pick the landlord who prorates.
Once the lease includes a proration clause, it's binding like any other term: the stated method and due-date convention control.
Move-out: check the notice clause first
Move-out proration is where refusals actually happen. Many leases require rent through the end of the final month, or through the full notice period, regardless of the day you hand back keys. If you give notice on the 10th and leave on the 20th, you may still owe the full month — legitimately.
The proration and notice clauses interact: read them together before assuming a partial-month refund at move-out.
The rule that does bind landlords: consistency
Whatever policy a landlord adopts — prorate or not, which method, which convention — fair-housing law requires applying it identically to every applicant and tenant. Prorating for one tenant and refusing another, without a documented business reason, is how a proration policy turns into a discrimination complaint.
That's the real takeaway for landlords: any reasonable proration policy is fine; an inconsistent one is not.
Frequently asked questions
Is a landlord required to prorate rent in Maryland?
No. No Maryland statute requires prorating rent for a mid-month move-in — it's a lease term. Once a proration clause is in the lease, it's binding as written.
Can a landlord refuse to prorate rent when I move out?
Often, yes — many leases require rent through the end of the final month or the full notice period regardless of the exact move-out date. Read the lease's notice and proration clauses together.
Can a landlord prorate rent for some tenants and not others?
That's the one real legal risk: fair-housing law requires applying the same policy to every applicant and tenant. An inconsistent proration policy without a documented business reason invites a discrimination complaint.
