Negligent security deadlines in CaliforniaYou usually have two years, sometimes more.

Most negligent security lawsuits in California must be filed within two years of the attack. An adult sexual assault claim usually has 10 years, a child's claim against a private owner generally waits until 18, and a claim against a public entity needs a written claim within six months first. A lawyer should calculate the dates in any one case.

In this guide

Law checked: November 11, 2026 (Code of Civil Procedure section 340.16, as updated January 1, 2026).

This page covers lawsuits after a crime on someone else's property: against the owner, landlord, property manager, business or security company, and against the attacker. Our negligent security page explains when an owner is responsible, the premises liability page covers other injuries on property, and the deadline calculator counts the general dates.

Filing deadlines

Most California injury lawsuits must be filed within two years of the injury (Code of Civil Procedure section 335.1). Some claims have more time. For a sexual assault that happened when the survivor was 18 or older, the lawsuit period is the later of 10 years from the last act or three years from when the survivor discovered, or reasonably should have discovered, the injury (section 340.16). A child's own injury claim against a private owner generally does not run while the child is under 18 (section 352). The dates in any one case should be calculated by a lawyer.

Deadlines by defendant

Each row below is one kind of defendant in a negligent security case, with its deadline for a violent attack, for an adult sexual assault, and for a person attacked before age 18. More than one row can apply to the same attack, and the deadlines do not all start on the same day. When they differ, the earliest one decides what has to happen first.

The attackerTwo years (Code of Civil Procedure section 335.1).

Domestic violence: the later of three years from the last act or three years from discovery (section 340.15).The later of 10 years from the last act or three years from discovery (section 340.16(a)).

A childhood sexual assault follows section 340.1.
Public entityIf a city, a county, the State, a school district, a transit agency or another public entity may be responsible, a written claim must first be presented to that entity within six months after the claim accrues (Government Code section 911.2). The lawsuit against the entity then has its own deadline: six months after a written rejection notice is delivered or mailed, or two years from the date the claim accrued if no written notice is given (Government Code section 945.6). If the six months pass, a late claim application may be made within one year under Government Code section 911.4, and it is not granted automatically.The same six month claim applies, because Government Code section 905 has no exception for an adult sexual assault. The second revival window expressly excludes a claim against a public entity (section 340.16(e)(7)(C)).A child's age does not pause the claim deadline against a public entity (Code of Civil Procedure section 352(b)). A childhood sexual assault claim needs no government claim (Government Code section 905(m)).

The two-year rule

Code of Civil Procedure section 335.1 allows two years for "An action for assault, battery, or injury to, or for the death of, an individual caused by the wrongful act or neglect of another." It names assault and battery, and it also covers a negligence claim against the owner, manager, business or security company whose failure let the attack happen. The two years usually run from the day of the attack. Two years is the general rule, and some claims have longer or shorter periods: an adult sexual assault, a child's own claim, a felony conviction and a claim against a public entity each change the dates.

No statute pauses the two years while a criminal case is pending, so the civil claim does not wait for an arrest, charges or a trial. Our guide for a tenant attacked by another tenant explains what to gather in the meantime.

Adult sexual assault

For an assault that happened when the survivor was 18 or older, Code of Civil Procedure section 340.16(a) sets the later of two periods: "10 years from the date of the last act," or three years from the date the survivor "discovers or reasonably should have discovered" that an injury or illness resulted from it. Section 340.16(b)(2) says the statute does not limit claims "against persons or entities other than the alleged person who committed the crime," which can include an owner, a hotel or a security company. It also says no criminal prosecution or conviction is needed. Our guide to sexual assault on someone else's property explains the claim and the privacy steps.

Revival windows with dates

Code of Civil Procedure section 340.16(b)(3) revived claims based on a sexual assault that happened on or after January 1, 2009, when the survivor was an adult, that had been barred only because the time limit ran out. Under the statute, those revived claims "may be commenced until December 31, 2026." A second window, in section 340.16(e), runs from January 1, 2026 through December 31, 2027. It revives adult sexual assault claims that were barred before January 1, 2026 because the time limit ran out, against an entity that "engaged in a cover up or attempted a cover up of a previous instance or allegations of sexual assault" by the same perpetrator, and against the perpetrator. The second window does not revive a claim against a public entity (section 340.16(e)(7)(C)), and a claim against a public entity also requires a written government claim, generally within six months (Government Code section 911.2). These dates were checked against the statute on November 11, 2026; whether a particular claim qualifies is a question for a lawyer.

Window dates and status

As of November 11, 2026, the date this page was checked, the window in Code of Civil Procedure section 340.16(b)(3) is open until December 31, 2026. After December 31, 2026, the section 340.16(b)(3) window is closed, and the 10-year and three-year periods in section 340.16(a) still apply. Neither window revives a claim that was litigated to finality or settled in a written agreement before the date the statute names: January 1, 2023 for the first window and January 1, 2026 for the second.

Children and teenagers

Code of Civil Procedure section 352(a) says that when the person who could sue was "under the age of majority" when the claim arose, "the time of the disability is not part of the time limited for the commencement of the action." For a child's own injury claim against a private owner, business or security company, the two years generally do not start until 18. Section 352(b) says this "shall not apply to an action against a public entity or public employee" where a government claim is required, so a child's age does not pause the six month claim. A parent's own claim, such as for a child's medical bills, should be checked separately by a lawyer.

A sexual assault on a child follows Code of Civil Procedure section 340.1, not section 340.16, and our school sexual abuse page explains those rules.

A felony conviction

Code of Civil Procedure section 340.3(a) can add time against an attacker convicted of a felony: "Unless a longer period is prescribed for a specific action," the lawsuit may be filed "within one year after judgment is pronounced." That helps only when it ends later than the usual period. For listed serious felonies, section 340.3(b) allows 10 years from the date the attacker is discharged from parole. Both rules reach only the person convicted, so they add no time against the owner, landlord, manager or security company. Restitution the attacker pays is credited against a recovery under section 340.3, and that recovery is subject to Government Code section 13963, the CalVCB repayment statute (section 340.3(e)).

CalVCB application deadline

An application to the California Victim Compensation Board (CalVCB) is not a lawsuit and has its own deadline. CalVCB says victims must apply "Within seven years of the crime, or Seven years after the direct victim turns 21 years of age, or Seven years from when the crime could have been discovered, whichever is later," and "Some applications filed later than this may be considered." CalVCB can reimburse up to $70,000, does not pay compensation for pain and suffering, and "is a payor of last resort." If a lawsuit is filed, the applicant or the lawyer "must notify CalVCB within 30 days of filing," and CalVCB is repaid from a later recovery for the same expenses. Our guide to the criminal case, CalVCB and your civil claim covers the application.

Dates to write down

A few dates decide most negligent security deadlines: the day of the attack, the day of the last act in a sexual assault, the day an injury was discovered, the date of any criminal judgment, and the day any government claim is presented or rejected. Write down whether a city, a county, a transit agency or another public entity owned or ran the property, because that decides whether the six month claim applies. Our negligent security evidence checklist lists the records that show these dates and who holds them.

Frequently asked questions

How long do you have to sue for negligent security in California?
Usually two years from the attack, under Code of Civil Procedure section 335.1. An adult sexual assault claim has the later of 10 years from the last act or three years from discovery (section 340.16). A child's own claim against a private owner generally does not run until 18 (section 352). If a public entity may be responsible, a written claim is due within six months (Government Code section 911.2). A lawyer should calculate the dates.
Is it one year or two years to sue for an assault in California?
Two years. Code of Civil Procedure section 335.1 allows two years for an action for assault, battery or injury caused by another's wrongful act or neglect. One year appears in one place: section 340.3(a) allows a lawsuit against an attacker convicted of a felony within one year after judgment, when that ends later than the usual period. It never shortens the two years.
Does the deadline wait for the criminal case to finish?
No. No statute pauses the civil deadline while a criminal case is pending, and the six month claim against a public entity is due whether or not anyone has been charged. If the attacker is convicted of a felony, Code of Civil Procedure section 340.3 can add time against that person only, not against the property owner or the security company.
How long does an adult have to sue for a sexual assault at a hotel or apartment?
Usually the later of 10 years from the last act or three years from discovery, under Code of Civil Procedure section 340.16(a), including against an owner or business. As of November 11, 2026, when this page was checked, a revival window for older claims is open until December 31, 2026, and a cover up window runs through December 31, 2027. The cover up window does not reach a public entity, and a public entity needs a written claim, generally within six months.
Does a child's age give more time to sue?
Against a private owner or business, generally yes: Code of Civil Procedure section 352(a) keeps the two years from running while the child is under 18. Against a public entity, no: section 352(b) means a child's age does not pause the six month claim. A parent's own claim, such as for medical bills, should be checked separately by a lawyer.
Is there a deadline to apply to CalVCB after an attack?
Yes. The California Victim Compensation Board says to apply within seven years of the crime, seven years after the direct victim turns 21, or seven years from when the crime could have been discovered, whichever is later, and it may consider some later applications. The application is separate from any lawsuit, and CalVCB must be notified within 30 days of filing one.
