The 30-day rule, explained for mid-term rental (MTR) hosts.

Why a furnished stay of about 30 nights can turn a guest into a tenant — what Airbnb says, a few state examples, and what mid-term rental (MTR) operators do about it. General information, not legal advice.

What the 30-day rule means

You’ll hear “the 30-day rule” used for two different lines. One is tenancy: when an occupant gains a tenant’s rights. The other is local rules and taxes: many cities regulate stays under 30 nights as short-term rentals, and many lodging taxes stop at around 30 days (see transient occupancy tax). A midterm rental sits right on both lines, which is why it matters.

Where the 30 days comes from

Examples of the 30-day line in official sources, as of September 2026 — not a complete list
TopicWhat it says
Airbnb (US hosts)In California, Illinois and New York, a residential tenancy may be created after 30 consecutive days of occupancy
CaliforniaThe landlord-tenant rules don’t cover transient hotel or motel occupancy that’s subject to local occupancy tax (Civ. Code 1940) — a tax cities can charge only on stays of 30 days or less (Rev. & Tax. Code 7280). A residential hotel can’t make someone move or re-register before 30 days to keep them “transient” (1940.1)
New YorkIn eviction cases, a hotel resident — not a transient occupant — who has been in possession for 30 consecutive days or longer counts as a tenant (RPAPL 711)
FloridaTransient public lodging is rented for periods of less than 30 consecutive days (Stat. 509.013), and the residential landlord-tenant part doesn’t apply to transient occupancy in a hotel, condominium, motel or similar lodging (83.42)
ArizonaThe landlord-tenant act excludes transient occupancy in a hotel, motel or recreational lodging, with no day count (A.R.S. 33-1308); the 30-day line is in the tax code, where “transient” means lodging for less than 30 consecutive days (42-5070)

Laws change and courts weigh the whole arrangement — a lease, mail, a move-in date — not just the calendar.

What operators do about it

Most mid-term operators don’t try to stay on the “guest” side of the line — they plan for the tenant side. We put every stay on a lease, drafted by our attorney, with 30 days’ notice to vacate. The clause-by-clause version is in mid-term lease agreements, and Airbnb’s side of it is in Airbnb monthly stays. Talk to a landlord-tenant attorney in your state before you set a minimum stay or a lease.

30-day rule FAQ

What is the 30-day rule for rentals?

A common name for the line between a guest and a tenant. In several states, a person who occupies a home or a hotel room for about 30 consecutive days or more can be treated as a tenant, with a tenant’s protections. Some cities and states also use 30 days as the line for short-term-rental rules and lodging taxes.

What is Airbnb’s 30-day rule?

Airbnb’s guidance for US hosts says that in California, Illinois and New York a residential tenancy may be created after 30 consecutive days of occupancy, and that someone who stays fewer than 30 days generally doesn’t have a tenant’s rights unless a written agreement says otherwise — but every state is different. It’s Airbnb pointing to state law, not an Airbnb policy.

Does staying 30 days automatically make someone a tenant?

Not automatically, and not everywhere. Some states write a day count into their laws; others, like Arizona’s landlord-tenant act, exclude “transient occupancy” in hotels and similar lodging without naming a number, and courts look at the whole arrangement. Check your state’s law with a landlord-tenant attorney.

Can you evict a mid-term tenant?

Yes, but if the law treats them as a tenant, you generally have to follow your state’s eviction process — written notice, then a court case — rather than asking them to leave like a hotel guest. That’s why most mid-term operators use a written lease with clear notice and move-out terms.

Is a 30-day rental a lease or a hotel stay?

It depends on the state and on what you signed. Many operators treat any stay of 30 nights or more as a tenancy and use a lease. For taxes, the line is separate: Arizona, for example, treats lodging of less than 30 consecutive days as transient lodging and longer stays as residential rentals.
