GPS Tracking Laws in California 2026 (Consent Requirements Explained)
California has some of the strictest GPS tracking laws in the United States. What's legal in Texas, Arizona, or Florida can get you charged with a misdemeanor in California. Employers who track company vehicles without written notice to employees, rental operators who monitor renters without disclosure, and individuals who track another person's car without consent all face real criminal and civil penalties under California law. Getting this wrong isn't just a compliance issue. It can cost you a professional license, result in a civil lawsuit, and put you in county jail.
I'm Ryan Horban, a GPS tracking expert with more than 15 years of hands-on experience helping rental operators, fleet managers, small business owners, and individual vehicle owners understand where GPS tracking is legal and where it crosses into criminal territory. California comes up in nearly every conversation I have with clients operating on the West Coast, and the rules here are genuinely different from every other state.
In this guide, I'll break down California Penal Code 637.7, the AB 984 employer tracking requirements, CCPA geolocation rules, consent requirements by situation, real court cases that define how these laws are applied, and exactly what rental car owners, Turo hosts, employers, and individuals need to do to stay legally compliant in 2026.
GPS tracking is legal in California when the registered owner, lessor, or lessee of the vehicle has given consent. Tracking someone without their consent, including a spouse, employee, or renter, is a misdemeanor criminal offense under California Penal Code 637.7. Employers must provide written notice before tracking employees in company-owned vehicles under AB 984. Penalties include up to six months in county jail, fines up to $1,000 per violation, civil damages up to $5,000 per violation, and professional license revocation for licensed business operators.

The Core Law: California Penal Code 637.7 Explained
California Penal Code 637.7 is the primary statute governing GPS tracking in California. It applies to individuals, businesses, employers, rental operators, and anyone using an electronic tracking device anywhere in the state.
The statute states directly:
"No person or entity in this state shall use an electronic tracking device to determine the location or movement of a person." — California Penal Code § 637.7(a)
That is a broad criminal prohibition. Two exceptions are written into the statute.
Exception 1: Ownership Consent
The registered owner, lessor, or lessee of the vehicle has consented to the use of the tracking device on that specific vehicle. [Cal. Penal Code § 637.7(b)]
Exception 2: Law Enforcement
A law enforcement agency is using the device through lawful means. [Cal. Penal Code § 637.7(c)]
Uses outside those statutory exceptions can create criminal and civil liability under California law. Most states allow vehicle owners to track their own property without restriction. California adds a layer that no other state matches in specificity: the person being tracked must also have consented or be the consenting owner.
What Counts as an Electronic Tracking Device Under PC 637.7
Under Cal. Penal Code § 637.7(d), an electronic tracking device means any device attached to a vehicle or other movable thing that reveals its location or movement through the transmission of electronic signals. This covers:
- OBD2 GPS plug-in trackers
- Hardwired GPS tracking devices
- Magnetic battery-powered GPS trackers
- Apple AirTags and Bluetooth location devices when used for movement monitoring
- Any attached software-enabled device that transmits location data
If the device tells you where something is or has been by transmitting a signal, it falls under PC 637.7 in California.
Important Boundary: Mollaei v. Otonomo Inc. (2022)
In Mollaei v. Otonomo Inc., Case No. 3:22-cv-02854 (N.D. Cal. 2022), a plaintiff argued that a data broker collecting GPS data from manufacturer-installed telematics control units violated CIPA § 637.7. The U.S. District Court dismissed the case, ruling that the statute applies to devices physically attached to a vehicle after manufacturing, not built-in factory components.
Aftermarket OBD2 trackers, magnetic trackers, and hardwired devices installed post-purchase are clearly covered by PC 637.7. Factory-installed telematics systems occupy a separate legal space, though that boundary continues to be litigated.
The Case That Defines Co-Owner Tracking: People v. Agnelli (2021)
The most directly relevant California GPS tracking case for vehicle owners is People v. Agnelli (2021), decided by the Superior Court of California, Orange County Appellate Division.
The Facts
Dustin Livingston Agnelli and his wife were going through a divorce. During the proceedings in April 2017, Agnelli installed a GPS tracking device on a vehicle both spouses still co-owned. He was charged and convicted under California Penal Code 637.7.
The Appeal and Ruling
Agnelli appealed, arguing that PC 637.7 was unconstitutionally vague as applied to his situation. His defense argued that because he was a registered co-owner of the vehicle, the ownership exception in PC 637.7(b) should apply to him.
Acting Presiding Judge Terri Flynn-Peister reversed the conviction on July 13, 2021, with two other judges concurring. The court ruled that PC 637.7 was unconstitutionally vague as applied to co-owners because the statute did not address what happens when both the tracker and the tracked person are registered owners of the same vehicle. The court wrote that neither the statute's language nor its legislative history addressed the multiple-owner question, leaving police, prosecutors, and juries without clear guidelines.
What This Means in 2026
The Agnelli case did not establish that co-owner tracking is legal. It established that the law is vague in that specific situation, which is a narrower and more technical finding. The California legislature has not amended PC 637.7 to close the co-ownership gap since 2021. Co-owners who install trackers without the other co-owner's knowledge still face civil claims and potential criminal charges under updated interpretations. The safest compliance position remains unchanged: get explicit consent from anyone whose movements the tracker will record.
United States v. Jones (2012): The Federal Baseline
The U.S. Supreme Court's unanimous ruling in United States v. Jones, 565 U.S. 400 (2012), established the federal constitutional floor for GPS tracking law nationwide.
In Jones, law enforcement attached a GPS device to Antoine Jones's vehicle and tracked his movements for 28 days without a valid warrant. The Supreme Court ruled unanimously that physically attaching a GPS device to a vehicle and using it to monitor movement constitutes a search under the Fourth Amendment, requiring a warrant.
The Jones ruling applies directly to government and law enforcement tracking. It does not restrict private individuals or businesses from tracking vehicles they own. However, the case confirmed that GPS tracking of a person's vehicle movements represents a constitutionally significant privacy intrusion, which has informed how California courts and legislators have interpreted and strengthened PC 637.7 in the years since.
California GPS Tracking Laws for Employers in 2026
Employers represent the largest category of GPS tracking users in California, and they face the most layered compliance requirements. Two laws apply simultaneously: California Penal Code 637.7 and AB 984, effective January 1, 2023.
What PC 637.7 Means for Employers
A company that owns its fleet vehicles is the registered owner and can consent to GPS tracking on those vehicles under PC 637.7(b). The company's consent as owner satisfies the ownership requirement. However, because tracking employees reveals the location and movement of a person, employers must ensure employees are aware of the tracking before it begins.
What AB 984 Added for Employers
AB 984, signed by Governor Gavin Newsom on September 29, 2022, and effective January 1, 2023, built directly on PC 637.7 and significantly tightened employer requirements. The key provisions in effect in 2026:
Employers cannot use a tracking device to monitor employees outside of work hours. [Cal. Lab. Code § 3823, as amended by AB 984]
Tracking must be strictly necessary for the performance of the employee's duties. GPS monitoring without a clear job-performance justification violates AB 984.
Employers must provide written notice to employees before tracking begins. The notice must include at minimum:
- A description of the specific activities that will be monitored
- A description of the worker data that will be collected
- The frequency of monitoring
- How the data will be used and stored
- The employer's name and contact information
This notice requirement applies even when the employer owns the vehicle. Ownership of the vehicle does not eliminate the employee notice requirement under AB 984.
These disclosure and consent requirements have become especially important for businesses using OBD trackers in fleet vehicles and take-home company cars. Employers implementing vehicle monitoring systems should also review our guide on employee privacy laws for company car GPS tracking for broader compliance considerations involving employee privacy, notice requirements, and after-hours tracking restrictions.
Penalties for Employer Violations
Civil penalties under AB 984 begin at $250 per employee for an initial violation and increase to $1,000 per employee for each subsequent violation. An employer tracking 20 employees without proper notice across multiple pay periods faces compounding liability quickly.
Criminal penalties under PC 637.7 remain available for egregious violations. A misdemeanor conviction carries up to 180 days in county jail and a fine of up to $1,000 per violation. [Cal. Penal Code § 637.7; Cal. Penal Code § 19]
Civil lawsuits under CIPA § 637.2 allow employees who are unlawfully tracked to pursue civil damages of $5,000 per violation or three times their actual economic damages, whichever is higher. Class action exposure is real when multiple employees are tracked without notice, as each affected employee represents a separate violation multiplied across the tracking period.
What Employers Must Do in 2026
- Provide written notice to all employees before activating GPS tracking
- Limit tracking to work hours only for vehicles used personally after hours
- Document the business justification for tracking each vehicle category or role
- Obtain signed employee acknowledgment confirming receipt of the notice
- Disable or pause tracking when a vehicle is used for personal trips outside work hours
- Review and update GPS tracking policies annually as California law continues to develop
California GPS Tracking Laws for Rental Car Owners and Turo Hosts
Under PC 637.7, the registered owner of a vehicle can consent to GPS tracking on their own property. A renter who signs a rental agreement is not the registered owner, lessor, or lessee in the legal sense of the statute unless the agreement specifically establishes that relationship.
The practical compliance requirement is a written disclosure in the rental agreement before the renter takes possession of the vehicle.
The Required Disclosure Language
One sentence in your rental agreement covers your legal obligation under California law:
"This vehicle is equipped with a GPS tracking device for security, fleet management, and theft recovery purposes. Location data may be monitored during the rental period."
That disclosure satisfies California's PC 637.7 requirement, meets Turo's policy requirement for GPS device disclosure, and creates a written record that the renter acknowledged the tracker's presence before driving away.

Turo's Policy Requirements in California
Turo explicitly permits GPS trackers in listed vehicles but requires hosts to disclose them in the vehicle description. Undisclosed tracking of renters is a policy violation that can result in account suspension. In California, a Turo host who fails to disclose a GPS tracker faces not just suspension but potential criminal liability under PC 637.7 if the undisclosed tracking is reported to law enforcement.
Apple AirTags and Bluetooth-only trackers are banned on the Turo platform-wide regardless of disclosure, because they raise surveillance concerns that extend beyond vehicle security.
What Rental Operators Cannot Do Even With a Disclosure?
A valid GPS disclosure in a rental agreement does not give rental operators unlimited license to use location data. Using GPS data to harass a renter, sharing location data with third parties without a documented legitimate purpose, or retaining detailed location records beyond what is needed for the rental period creates additional exposure under PC 637.7 and the California Consumer Privacy Act.
GPS Tracking Laws for Individuals in California
Individual use of GPS trackers is where California's law is strictest and where the most violations occur. The following situations generate the most legal questions in 2026.
Tracking Your Own Vehicle
Legal. If you are the registered owner installing and monitoring a tracker on your own vehicle for personal use, theft recovery, or location monitoring, you are within PC 637.7. The owner consent exception in § 637.7(b) applies directly to you.
Vehicle owners using GPS trackers for theft recovery, family safety, or day-to-day vehicle monitoring can also review our guide on Best Personal GPS Tracker for Cars, Kids & Pets (2026 Tests), which compares portable and real-time tracking devices for personal use.
Tracking a Spouse or Partner
Not legal without consent, even on a jointly owned vehicle. California courts have consistently charged and convicted individuals for this under PC 637.7. The People v. Agnelli case illustrates precisely how this plays out. Even though Agnelli's conviction was ultimately reversed on vagueness grounds specific to co-ownership, the case proceeded to trial and resulted in an initial conviction, confirming that law enforcement and prosecutors do charge these cases actively.
Installing a tracker on a vehicle your spouse regularly drives without their knowledge is the most common PC 637.7 violation charged in California. GPS trackers and surveillance tools are frequently involved in infidelity investigations and divorce disputes, but California law places strict limits on how they can legally be used. Readers researching the technology commonly associated with these cases can review our guide on Best Surveillance Devices for Cheating Spouse (2026 Guide).
The fact that both names may appear on the vehicle title does not protect you.
Tracking an Adult Child
Not without their knowledge. An adult child who drives a parent-owned vehicle may be subject to tracking if the parent has both installed the device and informed the adult child of its presence. Secret monitoring of an adult child's movements, even on a parent-owned vehicle, creates legal exposure under PC 637.7 regardless of intent.
Tracking a Minor Child
Generally permitted. Parents tracking minor children in vehicles the parent owns are within the law. The parental authority exception is not explicit in PC 637.7 but has been consistently supported by California courts when tracking is used for safety purposes. This does not extend to tracking a minor through a vehicle the minor owns or leases independently.
Tracking Someone Else's Vehicle
Criminal offence. Installing a GPS tracker on a vehicle you do not own, without the consent of the registered owner and the person whose movements the device will record, is a misdemeanour under PC 637.7, regardless of your reason for doing so.
The CCPA and Geolocation Data in 2026
California's GPS tracking laws extend beyond PC 637.7 into consumer data privacy law. The California Consumer Privacy Act (CCPA, Civil Code § 1798.100 et seq.) and the California Privacy Rights Act (CPRA, Proposition 24, 2020) both classify precise geolocation data as sensitive personal information subject to specific disclosure and consumer rights requirements.
What Businesses Must Do Under CCPA for GPS Data
Precise geolocation data, defined as location information identifying a person's location within a specific radius, must be disclosed in your privacy policy. California consumers have the right to know what location data is collected, how it is used, how long it is retained, and whether it is sold or shared with third parties. Businesses that collect sensitive geolocation data must allow consumers to limit use of that data to what is necessary for the stated purpose.
AB 1355: What Happened to the California Location Privacy Act
In February 2025, the California legislature introduced AB 1355, the California Location Privacy Act. The bill proposed requiring explicit opt-in consent before any collection of individual location data, strict data retention limits, a complete ban on selling or trading location data, and civil penalties of up to $25,000 per violation enforceable by the California Attorney General.
AB 1355 failed to advance and was filed as inactive in February 2026. [Cal. AB 1355, 2025-2026 Reg. Sess., filed pursuant to Joint Rule 56, Feb. 2, 2026.]
It is not currently law. However, the bill's failure does not signal a retreat from California's direction on location data. A substantially similar bill is expected to be reintroduced in the 2026-2027 legislative session. Businesses running GPS tracking operations in California should build data minimisation and documented consent practices now rather than waiting for a new bill to pass.

Compliance Checklist: What to Do Before You Track in California
For Rental Car Owners and Turo Hosts
- Add a one-sentence GPS disclosure to every rental agreement before the renter signs
- Include the disclosure in your Turo listing description
- Do not use AirTags or Bluetooth-only trackers on Turo vehicles under any circumstances
- Do not retain location data beyond the rental period without a documented operational reason
- Review your disclosure language whenever California privacy law updates
For Employers
- Provide written notice to every employee before activating GPS tracking as required by AB 984
- Limit tracking to work hours only for vehicles that employees use personally after hours
- Obtain signed acknowledgment from each employee confirming receipt of the written notice
- Document the specific business justification for each tracked vehicle or role
- Disable tracking outside work hours for take-home vehicles
- Store location data securely with access limited to personnel who have a business need
- Consult an employment attorney before expanding your tracking program beyond fleet vehicles
For Individuals
- Only install GPS trackers on vehicles registered in your name
- Inform anyone who regularly drives your vehicle that a tracker is installed
- Do not install a tracker on a vehicle you do not own without the registered owner's written consent
- Do not use GPS location data to monitor a person's movements without their knowledge
Conclusion
California's GPS tracking laws are the strictest in the country because the state's constitutional right to privacy extends further than the federal baseline. The legislature built PC 637.7, AB 984, and CCPA geolocation requirements around that right, and the courts have enforced them consistently, as both the prosecutions under PC 637.7 and the People v. Agnelli ruling demonstrate.
The core rules are not complicated. Get consent before tracking. Provide written notice as an employer. Disclose trackers in rental agreements. Limit employee tracking to work hours. Document everything.
Where people face legal trouble in California is almost never from deliberate intent to break the law. It's from assuming vehicle ownership gives unlimited tracking rights, that a general company policy satisfies the specific AB 984 notice requirements, or that a Turo listing without a one-sentence disclosure is close enough.
None of those assumptions hold up in California in 2026.
