California eviction service rules are changing, and landlords who handle their own evictions need to adjust how they serve and document. Beginning January 1, 2027, California law adds new requirements for how an eviction summons and complaint are served, how that service is proven, and what the eviction complaint must say about the notice that started the case. The rules for serving a 3-Day Notice itself have not changed, but the paper trail around it now matters more than ever.
What Changes for You as the Landlord
Under the prior rule, an unlawful detainer complaint had to state how the termination notice was served. Under the updated rule, the complaint must also state the date, time, and location where that notice was served. You can meet the requirement by completing the service items on the Judicial Council form complaint or by attaching a proof of service for the notice.
The practical takeaway is simple. Record the details the moment you serve a notice. Write down the date, the time, and exactly where and how it was served, take a photo of the notice, and save everything in the tenant file. A note on your phone is enough. Reconstructing those details from memory weeks later is where mistakes happen.
Who Can Serve the Eviction Summons
Once an eviction is filed, the tenant must be formally served with the summons and complaint. California law allows any person who is at least 18 years old and not a party to the case to serve a summons, which means the landlord cannot do it personally. Most landlords use a process server, and that is where most of the new requirements apply.
The Three-Attempt Standard
Before a summons can be left with another adult at the tenant's home, known as substituted service, the server must show reasonable diligence in trying to hand it to the tenant directly. Under the updated law, reasonable diligence means at least three good-faith attempts at personal delivery, on three different days, at three different times. When substituted service is used, a copy is also mailed, and service is not complete until the tenth day after mailing.
Posting the summons at the property is still available in eviction cases, but it requires a court order. The same three-attempt standard applies, at least one attempt must be made at the tenant's home when it is known, and service by posting is complete on the tenth day after posting and mailing. Landlords should build these waiting periods into their timelines from the start.
Photo and GPS Proof of Service
Proof of personal service, substituted service, or posting must now include a photograph of the site of each completed or attempted service. Each photo must carry a readable stamp recording the date, time, and GPS or equivalent coordinates, and at a home, at least one photo must show the door or entrance. If there is no signal, the server must explain the missing stamp. If taking a photo would compromise the server's safety, the server may skip it and must explain why. The photos become part of the proof of service filed with the court.
Why This Matters: A Default Judgment Is Only as Strong as Its Service
Many evictions end in a default judgment because the tenant never responds. Under the updated law, a tenant who claims they were not properly served can move to set aside the default. Once the tenant offers evidence that service was not lawful, the burden shifts to the landlord to prove that it was. If the landlord cannot, the judgment can be set aside and the case reopened.
That makes choosing a process server one of the most important decisions in the eviction. Before hiring one, ask three questions. Are you a registered process server? County registers of process servers are becoming publicly available, so registration can be verified. Are you set up to meet the photo and GPS requirements on every attempt, not just the successful one? Will I receive copies of the photos with the proof of service? A server who cannot answer clearly is not a bargain, regardless of price.
What a Do-Over Can Cost
Consider an illustrative example. A Stockton rental leases for $2,000 per month. A default judgment is set aside over defective service, and reopening the case and returning to judgment adds six weeks. That is roughly $3,000 in rent that is not being collected, before the cost of serving and litigating a second time. Actual delays and costs vary, but the pattern is consistent. The expensive part of an eviction is rarely the filing fee. It is the restart.
Key Takeaways
Record the date, time, and location every time you serve a notice. Plan for three delivery attempts and a ten-day completion period. Hire a registered process server who documents every attempt, and keep your own records clean.
