Most people who are injured in California know they have two years to file a personal injury lawsuit under CCP Section 335.1. What most people do not know is that when the party responsible for their injury is a government entity, the deadline is not two years. It is six months. Under Government Code Section 911.2, any person who suffers bodily injury caused by a California government entity must file a formal administrative claim within six months of the date of injury. This is not a suggestion, not a best practice, and not a guideline. It is an absolute prerequisite to filing a lawsuit. If you miss this deadline, your right to sue is gone in the vast majority of cases, regardless of how severe your injuries are or how clearly the government was at fault.

This deadline catches many people off guard. Often the reason is simple: people do not realize that the entity that injured them is a government entity. They fell on a cracked sidewalk and assumed it was the adjacent property owner's responsibility. They were hit by a city bus and focused on getting medical treatment, not on filing paperwork. They were injured on a state highway and did not think of Caltrans as a party they needed to formally notify. By the time they hire an attorney and learn about the six-month deadline, it is often too late.

This guide explains exactly what the six-month government claim deadline is, who it applies to, how to file a timely claim, and what limited options exist if you miss it. For a broader overview of California personal injury law, see our California personal injury lawyer resource page.

What Is the Government Claims Act?

The California Government Claims Act, codified in Government Code Sections 810 through 996.6, establishes the exclusive procedure for bringing lawsuits against public entities in California. Originally known as the California Tort Claims Act, the statute was enacted in 1963 as part of a comprehensive overhaul of government liability law. Before 1963, California followed the doctrine of sovereign immunity, which meant government entities generally could not be sued at all. The Government Claims Act changed that by allowing lawsuits against government entities, but only if the claimant first complied with a mandatory administrative claims process. The California Supreme Court has repeatedly held that compliance with the claims process is a condition precedent to filing suit, and failure to comply bars the action entirely.

The Purpose Behind the 6-Month Deadline

The legislature imposed the six-month deadline to give government entities prompt notice of potential claims so they can investigate while evidence is fresh, preserve relevant records, and budget for potential liabilities. The California Law Revision Commission, which drafted the original legislation, noted that government operations differ from private enterprises in scale and complexity, and that early notice is essential for effective claims management. The practical effect, however, is that injured individuals face a filing deadline far shorter than the standard two-year statute of limitations. Courts have consistently upheld it, and the late claim process under Government Code Sections 911.4 and 946.6 provides only a limited safety valve.

Government Claims Act vs. Standard Statute of Limitations

It is critical to understand that the government claim is not the same thing as filing a lawsuit. The administrative claim is a prerequisite to filing a lawsuit. Here is how the timeline works: you file your administrative claim within six months. The government entity then has 45 days to respond. If the entity denies the claim (or fails to respond within 45 days, which constitutes a deemed denial), the deadline to sue is set by Government Code Section 945.6. If the entity sends a written notice of rejection, you have six months from that notice to file a lawsuit. If no written rejection notice is sent, the deadline to sue is generally two years from the injury.

Deadline	Timeframe	Governing Law	Applies To
Administrative claim filing	6 months from injury	Gov. Code § 911.2	All claims against government entities
Government response	45 days from claim receipt	Gov. Code § 912.4	Government entity must accept, deny, or let lapse
Lawsuit filing after denial	6 months from written rejection notice; 2 years if no written notice	Gov. Code § 945.6	After claim denied or deemed denied
Late claim petition	1 year from injury	Gov. Code § 911.4	If original 6-month deadline missed
Court petition for late filing	6 months from late claim denial	Gov. Code § 946.6	If late claim petition denied by entity

What Counts as a Government Entity in California?

The Government Claims Act applies to an extremely broad range of public entities, and this breadth is why so many people miss the deadline. It covers the state, its agencies, counties, cities, and special districts ranging from school districts to water authorities to transit agencies. Any injury caused by the negligence of any of these entities or their employees requires a timely government claim.

Cities, Counties, and Municipal Agencies

The most common government claim scenarios involve city and county negligence. Cracked and buckled city sidewalks lead to trip-and-fall claims. Potholes on county roads in Los Angeles County, San Bernardino County, and San Diego County cause vehicle damage and motorcycle crashes. City-operated parks with broken playground equipment, poorly maintained trails, and defective sports facilities injure visitors. Municipal pools with inadequate supervision or defective drains create drowning and injury risks. Any claim arising from these scenarios must be filed with the appropriate city or county clerk within six months.

State Agencies: Caltrans, CHP, State Parks

Injuries on state-maintained highways are governed by claims against the California Department of Transportation (Caltrans). Highway defects, inadequate signage, missing guardrails, poorly designed interchanges, and construction zone hazards on roads like Interstate 5, Interstate 10, the 101, and Highway 99 all require a timely claim against the State. Injuries in state parks operated by the California Department of Parks and Recreation, incidents involving California Highway Patrol officers, and claims against state hospitals and correctional facilities all follow the same six-month deadline.

Public Transit: LA Metro, BART, AC Transit, and More

California's public transit agencies are government entities subject to the claims act. LA Metro, BART (Bay Area Rapid Transit), AC Transit, SF Muni, San Diego MTS, Sacramento RT, and dozens of smaller transit agencies all require six-month claim filing. Bus crashes, light rail accidents, injuries from sudden stops, slip and falls on transit property, and pedestrian strikes by transit vehicles all trigger the claims act deadline. Passengers who are injured when a bus driver brakes suddenly or a train derails must file against the transit agency, not against an individual driver.

School Districts and Public Universities

Injuries occurring on public school grounds and public university campuses involve government entities, including public school districts, California State University and University of California campuses, and community colleges. Playground injuries, school bus accidents, athletic injuries caused by defective equipment or negligent supervision, and sexual abuse claims against school employees all require timely government claims. The claim must be filed with the school district's governing board or the university's claims administrator, and the six-month deadline applies regardless of whether the victim is a minor. However, for minors, the late claim petition process under Government Code Section 911.4 may provide additional relief.

How to File a Government Claim in California

Filing a government claim in California requires more than simply notifying the entity that you were injured. The claim must contain specific information mandated by Government Code Section 910, and deficiencies in the claim can result in rejection or, worse, a finding that the claim was not legally sufficient to satisfy the prerequisite. The Government Claims Program processes claims against the State of California, while claims against cities, counties, and special districts are filed directly with those entities. Each entity may have its own claims form, filing address, and processing procedures, and identifying the correct entity and filing location is the claimant's responsibility.

Required Information Under Gov. Code Section 910

A compliant government claim must include: the claimant's name and post office address; the post office address to which the claimant desires notices to be sent; the date, place, and other circumstances of the occurrence giving rise to the claim; a general description of the injury, damage, or loss incurred; the names of any public employees who caused the injury (if known); and the amount claimed, stated in the form Section 910 requires. Failure to include any of these elements can be grounds for the entity to reject the claim as insufficient, although courts have sometimes excused minor deficiencies when the claim substantially complies with the statutory requirements.

Where to File: Identifying the Correct Entity

One of the most common mistakes claimants make is filing with the wrong entity. If you were injured on a city sidewalk, the claim goes to the city clerk of that particular city. If you were injured on a county road, it goes to the county clerk or county counsel. If you were injured on a state highway, the claim goes to the California Department of General Services, Office of Risk and Insurance Management, which processes claims against state agencies including Caltrans. If you were injured by a public transit vehicle, the claim goes to the transit agency's claims department. A claim sent to the wrong office may not count, and the deadline keeps running, so confirming the correct entity early matters.

The six-month government claim deadline can end an otherwise valid claim before it starts. If you were injured on government property or by a government vehicle, it helps to talk with an attorney within days, not weeks.

Common Scenarios That Trigger the 6-Month Deadline

The government claim requirement applies to a far wider range of situations than most people realize. Below are the most common scenarios that trigger the requirement, along with the specific considerations that apply to each.

Cracked Sidewalks and Pothole Injuries

Defective sidewalks and potholes are a frequent source of government injury claims in California. Under Streets and Highways Code Section 5610, the owners of property fronting a public street are generally responsible for maintaining the adjacent sidewalk. However, in many cities, the municipality retains some level of responsibility, particularly when the damage was caused by city-planted trees or city infrastructure. Any trip-and-fall claim against a city requires a timely government claim.

City Bus and Public Transit Crashes

When an LA Metro bus rear-ends your car, or you are injured as a passenger when a San Francisco Muni train brakes suddenly, the responsible party is a government entity. Public transit operators are held to a common carrier standard of care, which is the highest duty of care under California law: they must use the utmost care and diligence for the safe carriage of passengers. That heightened standard does not change the six-month deadline, and a late claim can end a case regardless of fault. If you were injured in any incident involving a public transit vehicle, file your government claim immediately and preserve all evidence including transit schedules, route maps, and any video footage from onboard cameras.

State Highway Defects and Caltrans Liability

Caltrans is responsible for maintaining California's state highway system, including Interstates 5, 10, 15, 80, and 405, as well as major state routes like Highway 1, Highway 99, and Highway 101. Highway defects that can give rise to claims include missing or damaged guardrails, inadequate signage at construction zones, defective road surfaces, debris left by maintenance crews, improperly designed on-ramps and off-ramps, and failure to address known hazardous conditions. Claims against Caltrans are filed with the Department of General Services and must comply with the standard six-month deadline.

Public Building Falls and Government Property Injuries

Falls in government buildings including courthouses, DMV offices, public libraries, city halls, and post offices all require government claims. So do injuries in public parks, on public beaches, at government-operated recreational facilities, and on government-owned parking structures. The City of San Diego, Los Angeles County, and the State of California all maintain extensive property portfolios, and maintenance failures on these properties are common. Wet floors in a county courthouse, a broken stairway railing in a state office building, and an uneven walkway in a city park all trigger the claims act requirement and the six-month deadline.

What Happens If You Miss the 6-Month Deadline

Missing the six-month government claim deadline does not always mean your case is over, but the path to recovery becomes significantly narrower and less certain. California law provides a limited safety valve through the late claim petition process, but the standards for approval are strict, the timelines are tight, and success is far from guaranteed.

Late Claim Petition: Gov. Code Section 911.4

If you miss the six-month deadline, your first step is to file a late claim application with the government entity under Government Code Section 911.4. This application must be filed within one year of the date of injury. In the application, you must demonstrate that your failure to file a timely claim was due to mistake, inadvertence, surprise, or excusable neglect. Grounds can include physical or mental incapacity during the six-month period, or the claimant being a minor during that period. Simply being unaware of the deadline, without more, is generally not sufficient grounds for relief.

Court Petition: Gov. Code Section 946.6

If the government entity denies your late claim application (or fails to respond within 45 days, which constitutes a deemed denial), you can petition the Superior Court for relief under Government Code Section 946.6. This petition must be filed within six months of the denial. The court applies the same standards as the administrative process, focusing on whether the failure to file was the result of mistake, inadvertence, surprise, or excusable neglect. The court may also consider whether granting the petition would prejudice the government entity. Courts have significant discretion, and outcomes vary.

When There Is No Relief Available

If you miss both the six-month filing deadline and the one-year late claim petition deadline, your options are usually exhausted. Courts generally cannot grant relief once the one-year late-claim window has passed, apart from narrow, fact-specific exceptions. That is why it helps to consult an attorney promptly after any injury involving a government entity.

0-6 months: File standard government claim (Gov. Code § 911.2)
6-12 months: File late claim petition with government entity (Gov. Code § 911.4)
After entity denies late claim: File court petition within 6 months of denial (Gov. Code § 946.6)
After 1 year: Deadline is generally jurisdictional; no court relief available in most cases
Minors: Additional protections may apply, but the claim must still be filed

Why This Deadline Catches So Many People Off Guard

The six-month government claim deadline is one of the easiest procedural rules to miss in California personal injury law. A few common patterns explain why, and knowing them can help you avoid missing it.

People Do Not Realize the Defendant Is a Government Entity

This is the most common reason people miss the deadline. A person trips on a cracked sidewalk and assumes the adjacent business is responsible. A person is hit by what appears to be a privately branded shuttle but is actually operated by a public transit authority. A person is injured in a building that looks private but is actually owned by a government redevelopment agency. In California, many government functions are performed by entities that do not obviously appear to be government agencies. Special districts operate water systems, fire protection, healthcare, transit, parks, and mosquito abatement, among other functions. Injuries caused by any of these entities require a government claim, and the injured person is responsible for identifying the entity correctly.

The Focus on Medical Recovery Delays Legal Action

After a serious injury, the immediate priority is medical treatment and physical recovery. Filing government paperwork is not at the top of anyone's mind when they are in a hospital bed recovering from surgery or managing chronic pain from a truck accident on a state highway. The six-month deadline does not account for the reality that seriously injured people are often unable to focus on legal requirements during the period when the deadline is running. While the late claim petition process under Section 911.4 can provide relief for physical incapacity, the standard is strict, and courts require evidence that the incapacity actually prevented the claimant from filing or directing someone else to file on their behalf.

Attorney Retention Often Happens Too Late

Many injury victims do not consult an attorney until months after the accident, often because they initially believe their injuries are minor or because they attempt to negotiate directly with the responsible party's insurance. By the time they hire an attorney who identifies the government entity involvement, the six-month deadline may have passed. This problem is compounded in cases involving mold exposure in public housing or latent injuries from government property defects, where the connection between the injury and the government entity may not be apparent for weeks or months.

Frequently Asked Questions

What is the deadline to file a claim against a California government entity?

You must file a formal administrative claim within six months of the date of injury under Government Code Section 911.2. This is a mandatory prerequisite to filing a lawsuit. Missing this deadline will bar your claim in most cases.

Can I file a late government claim in California?

Yes, but only within one year of the date of injury under Government Code Section 911.4. You must demonstrate that the delay was caused by mistake, inadvertence, surprise, or excusable neglect. If the entity denies your late claim, you can petition the Superior Court under Section 946.6, but approval is not guaranteed.

Does the 6-month deadline apply to car accidents with government vehicles?

Yes. If you were injured in a collision with a city bus, county vehicle, Caltrans truck, CHP patrol car, or any other government-owned or government-operated vehicle, you must file a government claim within six months. The common carrier standard of care applies to public transit, but the claims filing deadline is the same.

What happens if the government ignores my claim?

If the government entity fails to respond within 45 days of receiving your claim, it is deemed denied by operation of law under Government Code Section 912.4. If no written rejection notice is sent, Government Code Section 945.6 generally allows two years from the injury to file a lawsuit. If a written rejection notice is sent, the deadline is six months from that notice.

Who do I file a government claim with if I fell on a city sidewalk?

You file the claim with the city clerk of the city that owns or maintains the sidewalk. In some jurisdictions, liability may also involve the adjacent property owner under Streets and Highways Code Section 5610. An attorney can help you identify all potentially liable parties and ensure claims are filed with each correct entity within the six-month deadline.
