Serve the wrong notice and the judge throws out your case before it starts. That is the entire stakes of the 30 day vs 60 day eviction notice question. In California, the rule is a single bright line: a tenant who has lived in the unit less than a year gets 30 days, a tenant there a year or more gets 60. Get the side of the line wrong and you lose two months starting over.
30 day vs 60 day eviction notice: the rule
Both notices end a month-to-month tenancy without fault, meaning the tenant has not done anything wrong and you simply want the unit back. The 30-day notice applies when every tenant or resident has lived in the property for less than one year. The 60-day notice applies the moment anyone has been there a year or more. That "anyone" matters: if one roommate moved in 14 months ago and another moved in last month, the tenancy is over a year old and you owe 60 days.
Count from the move-in date, not from when you bought the building. A landlord who purchases a property inherits the tenants' tenure. Buy a duplex in June with a tenant who moved in three years ago, serve a 30-day notice in July, and the notice is void. You have to start over with a 60-day notice, and the clock restarts from zero. That mistake costs you roughly two months of rent and a filing fee.
The overlays that change the answer
California's Tenant Protection Act, AB 1482, adds a layer on top of the timeline. In covered properties, once a tenant has been there 12 months, you need a valid just cause to end the tenancy at all, even with the correct notice period. Valid no-fault reasons include moving yourself or immediate family in, substantial remodeling that requires permits and makes the unit uninhabitable, or taking the property off the rental market. The 30/60 day clock is the procedure. Just cause is the permission slip.
Subsidized housing plays by its own rule: Section 8 tenancies generally require a 90-day notice with the reason stated. And if you think California is strict, look at Chicago, where the Fair Notice rules require 120 days for tenants of more than three years. The pattern across the country is the same, longer tenancy means longer notice, but the exact numbers are state and sometimes city law. There is no national rule.
The decision rules
If you are unsure which side of the line you are on, serve the 60-day notice. The longer notice is never the wrong one for a no-cause termination. It costs you 30 days of patience and it never gets your case dismissed.
If the tenant owes rent or broke the lease, you are probably in 3-day notice territory, not 30/60. Do not use a no-cause notice to dodge the rules for a for-cause situation, and do not use a for-cause notice when the tenant has done nothing wrong. Judges see through both.
And remember what these notices are not. Neither one is an eviction by itself. If the tenant does not leave when the notice expires, you still have to file an unlawful detainer lawsuit and win it. The notice is step one of a legal process, not a self-executing order, and acting like it is, changing the locks, shutting off utilities, will cost you far more than the rent you are trying to protect.
Not legal advice: notice periods and just-cause rules are state and sometimes city specific, and they change. Confirm the notice type, timeline, and required language for your jurisdiction, and use a landlord-tenant attorney for anything contested.
Frequently asked questions
Does the 30/60 day rule apply to fixed-term leases?
No. The 30 and 60 day notices end month-to-month tenancies. A fixed-term lease ends on its own expiration date, and you generally cannot terminate it early without cause.
What if I bought the property with tenants already in it?
You inherit their tenure. Count from their original move-in date, not from your purchase date. Serving a 30-day notice on a tenant of two years voids the notice.
When is a 90-day notice required?
Section 8 and other subsidized tenancies generally require a 90-day notice stating the reason. Some cities add their own longer windows, like Chicago's 120 days for tenancies over three years.
Can the tenant fight a 30 or 60 day notice?
They can challenge it in the unlawful detainer case that follows if the notice is defective: wrong time period, improper service, or missing just-cause where the law requires it. That is why serving the correct notice matters so much.
