How to Evict a Tenant With No Lease in California

The belief that a tenant without a written lease can be told to leave on short notice is the most expensive misunderstanding in California landlord-tenant law. No lease does not mean no tenancy. If someone pays you rent and you accept it, the law creates a periodic tenancy — almost always month-to-month — and that tenant has materially the same rights as one holding a signed twelve-month agreement.

What You Actually Have

Where rent is paid monthly and nothing in writing says otherwise, you have a month-to-month tenancy. It renews automatically each period. It ends when one side gives proper statutory notice, or when a court orders possession — not when you decide it has ended.

The absence of a lease actually works against you in one specific way: you have no written terms to point to. There is no clause prohibiting pets, no clause limiting occupants, no clause requiring notice of entry. Every restriction you thought applied has to come from statute instead.

Thirty Days or Sixty Days

Civil Code section 1946.1 sets the notice period for terminating a month-to-month tenancy, and it turns on how long the tenant has lived there:

  • Less than one year: thirty days’ written notice.
  • One year or more: sixty days’ written notice.

The tenant, by contrast, only ever owes you thirty days. The asymmetry is deliberate.

Note that this is the notice period, not the eviction. If the tenant is still in the unit when the notice expires, you are back to the unlawful detainer process — the notice merely makes the holdover unlawful.

Just Cause Does Not Care Whether You Signed Anything

This is the part that catches owners out. Civil Code section 1946.2 attaches just-cause protection to continuous occupancy of twelve months. It says nothing about a written agreement. Your handshake tenant of three years is protected exactly as a tenant on paper would be.

So once that tenant passes twelve months, a bare sixty-day notice is not enough. You need a just cause from the statutory list, the notice must state it, and if the cause is no-fault — owner move-in, withdrawal from the market, government order, substantial remodel — you owe relocation assistance of one month’s rent within fifteen calendar days.

Proving the move-in date is your problem, not the tenant’s, and without a lease you may have nothing but bank deposits and text messages. Reconstruct the record before you serve anything.

The Lodger Exception, and How Narrow It Is

Civil Code section 1946.5 carves out a genuinely different rule for a lodger — but it is far narrower than most people hoping to use it realise. It applies where there is a single lodger in a dwelling that the owner occupies, and where the owner retains the right of access to all areas the lodger uses.

One lodger. Owner living there. Full access retained. Take in a second lodger and the exception evaporates for both. Move out yourself and it evaporates. Give the lodger a private entrance and exclusive use of their space and you have probably created an ordinary tenancy.

Where it genuinely applies, notice equal to the rental period terminates the arrangement and the lodger becomes a trespasser at expiry. Where it does not, relying on it is how owners end up defending a wrongful eviction claim.

Family, Friends, and People Who Never Paid Rent

These are the hardest cases, and the ones where owners most often act rashly. A relative you let stay rent-free, an ex-partner who will not move out, a friend who was supposed to be there for a fortnight — none of them are trespassers simply because no money changed hands.

Courts look at whether the person has established residence: do they receive post there, keep their belongings there, have a key, treat it as home? If yes, they are an occupant to be removed through the courts, and calling the police will usually produce an officer who declines to intervene in what they correctly identify as a civil matter.

Put It in Writing, Even Now

If you intend to keep the tenant, a written month-to-month agreement signed today gives you terms you can enforce going forward. It does not reset the occupancy clock for just-cause purposes, and it will not retroactively create obligations the tenant never agreed to, but it ends the argument about what the arrangement is.

Refusing to sign a written renewal on substantially similar terms is itself an at-fault just cause under section 1946.2 — so a tenant who declines a fair written agreement has given you something you did not previously have.
