Can a California Landlord Evict Without a Lease — or "For No Reason"? What the Law Actually Allows
In California, a landlord usually cannot evict a tenant "for no reason" once the tenant has lived in a covered unit for 12 months or more — the Tenant Protection Act requires "just cause." A tenant without a written lease is still a tenant, typically month-to-month, and can only be removed with the correct termination notice and, where just-cause rules apply, a qualifying reason. Whether your property is covered depends on the unit type, its age and ownership, and your city's local ordinance.
Two beliefs get California owners into trouble more than almost any others: that a tenant without a written lease is easy to remove, and that a landlord can end a tenancy for any reason on proper notice. Both are often wrong. Here is what the law actually allows, framed from the owner's side.
A tenant without a lease is still a tenant
When there is no written lease — or the lease has expired and the tenant stayed on — the arrangement is usually a month-to-month tenancy. That is a real tenancy with real protections. The absence of a signed document does not mean the tenant can be removed informally. You still have to serve a proper termination notice, and self-help removal remains illegal. In practice, "no lease" changes very little about the process you have to follow.
The Tenant Protection Act and "just cause"
California's Tenant Protection Act introduced a statewide just-cause requirement. For covered units, once a tenant has lawfully occupied the property for 12 months or more, the owner generally needs just cause to end the tenancy. Just cause comes in two categories. At-fault reasons include nonpayment of rent, a material lease breach, nuisance, and similar tenant conduct. No-fault reasons include an owner or qualifying relative moving in, withdrawing the property from the rental market, substantial remodel or demolition, and compliance with a government order.
The distinction matters because no-fault terminations generally require the owner to provide relocation assistance — often the equivalent of a month's rent or a rent waiver. Getting that step wrong can invalidate the termination.
Is your property even covered?
Not every unit is subject to the statewide just-cause rules. Common exemptions include single-family homes and condominiums that are not owned by a corporation or certain institutional owners (provided the required notice is given to the tenant), housing built within roughly the last 15 years, and owner-occupied duplexes. Whether a specific property is covered or exempt is a fact-specific question — and assuming the wrong answer before serving a notice is an expensive mistake.
Local ordinances can be stricter
The statewide law is a floor, not a ceiling. Cities across the Bay Area and Southern California — San Francisco, Oakland, Berkeley, San Jose, Los Angeles, and others — have their own just-cause and rent-control ordinances. Local rules can cover units the state law exempts, add their own list of allowed reasons, require larger relocation payments, and impose extra filing or notice steps. If your property is in one of these cities, the local ordinance often controls the analysis, and it frequently demands more than the state minimum.
"No reason" evictions: where they are still possible
There are situations where a no-cause termination — ending a month-to-month tenancy on a proper 30-day or 60-day notice without stating a reason — remains permissible: generally where the just-cause rules do not apply, such as an exempt unit, a tenancy under 12 months, and no local ordinance imposing cause. But the key word is "where." The permissibility turns entirely on the coverage analysis, so the safe move is to confirm whether your unit is covered before assuming you can end a tenancy without a reason.
The bottom line for owners
For most California owners, the real question is not whether you can remove a tenant — it is on what grounds and through what process. That starts with correctly determining whether your property is covered by state and local just-cause rules, because everything else follows from that answer. It is the kind of determination worth getting right before you serve anything.
