SB 871 (Domestic Violence Prevention Act) requires courts issuing protective orders in qualifying domestic violence cases to order continuous electronic monitoring of the alleged offender. The bill defines minimum technical attributes for the monitoring device, mandates immediate transmission of exclusion/proximity violations to law enforcement and the protected party, and requires counties to contract with qualified providers and designate response agencies.
The measure matters because it builds a statewide, technology-driven tool aimed at preventing domestic violence homicides and serious assaults, while simultaneously creating new procurement, operational, and legal obligations for courts, counties, law enforcement, and monitoring vendors. It also shifts most costs to alleged offenders subject to monitoring, with a statutory path for waivers where a court finds inability to pay.
At a Glance
What It Does
The bill directs courts to order continuous electronic monitoring for alleged domestic violence offenders who meet specified high-risk criteria and establishes minimum device features (wearable, 24/7, tamper‑resistant, broadly locatable). Monitoring must operate in real time; breaches of court-ordered geographic exclusion or proximity zones are transmitted immediately to local law enforcement and the protected party. Counties and municipalities must execute written contracts with qualified service providers and designate agencies to respond to violations.
Who It Affects
State and superior courts issuing protective orders, county governments responsible for contracting and response, probation and local law enforcement that will receive and act on real-time alerts, private monitoring vendors bidding on contracts, alleged offenders subject to protective orders, and survivors who may receive notification apps or receptor devices.
Why It Matters
SB 871 institutionalizes technology-based supervision for high-risk intimate partner cases, potentially reducing lethal outcomes but demanding new operational capacity—procurement, 24/7 monitoring centers, and frontline staffing—to respond to alerts. It also raises legal and administrative questions about cost-shifting, indigence determinations, technical feasibility, and the handling of monitoring data.

What This Bill Actually Does
SB 871 adds a new Article 1.5 to California law creating a court-ordered continuous electronic monitoring regime targeted at higher-risk domestic violence cases. The statute sets out the Legislature’s intent to prevent domestic violence homicides and then defines what ‘‘continuous electronic monitoring’’ means in practical terms: a wearable device that emits a signal around the clock, resists tampering, and is designed to be locatable across urban and rural areas and within structures to the extent technically feasible and cost‑appropriate.
When a court issues a protective order and the alleged offender meets the bill’s listed risk criteria, the court must require the person to wear the device and may require the person to pay the system’s operating costs. The court also may require the offender to pay for a victim-facing cellular application or receptor device, but only with the victim’s consent.
Importantly, the statute prevents inability to pay from blocking use of monitoring: a court can impose payment only after a finding of ability to pay, and must waive payment when the court finds inability to pay.The bill places operational responsibilities on counties and municipalities: courts must use written contracts and qualified providers, and each county or municipality must enter agreements with contract service providers. Counties must also designate a responsible agency to respond to monitoring violations.
Devices must produce continuous, real-time monitoring and transmit violations of exclusion or proximity conditions immediately to local law enforcement and the protected party, and operators are explicitly ordered to notify appropriate law enforcement personnel and emergency communications dispatch centers when an offender violates a condition of court supervision.Taken together, the statute creates a legal framework for a statewide, court-managed ecosystem that combines judicial supervision, contracted technical services, and frontline emergency response. The text leaves detailed implementation choices—procurement standards, data retention, precise dispatch protocols, and the operational definition of ‘‘technically feasible’’ location capability—to courts, counties, and vendors, which means the day‑to‑day shape of the program will vary by jurisdiction.
The Five Things You Need to Know
The court must order continuous electronic monitoring when the alleged offender’s conduct includes strangulation/suffocation, use or threatened use of a deadly weapon, serious bodily injury, violation of a protective order tied to domestic violence, or a prior domestic violence conviction within five years.
A monitoring device must be wearable, operate 24 hours per day, be resistant to damage or tampering, and emit a signal that can be received and tracked across urban and rural areas and inside structures to the degree technically feasible and cost‑appropriate.
The court may require the alleged offender to pay for monitoring and, if the victim consents, to pay for a victim-facing app or receptor device; inability to pay cannot prevent monitoring, and courts must waive payments upon a finding of inability to pay.
Violations of court-ordered geographic exclusion zones or proximity restrictions must be transmitted immediately to local law enforcement and to the protected party, and monitoring operators must notify the appropriate law enforcement employee and emergency communications dispatch center regarding breaches.
Monitoring stays in effect until case disposition or further court order, and each county/municipality must enter written contracts with qualified providers and designate an agency to respond to monitoring violations.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Findings and legislative intent
This section records the Legislature’s public‑safety rationale for a technology-driven approach: rising severity in domestic violence incidents, the risk to children and homicide statistics, and references to other states’ programs. That framing matters because it anchors implementation choices (prioritizing high-risk cases) and will likely be cited in budget, policy, or litigation debates to justify expenditure and program scope.
Definition and administrative framework for continuous monitoring
Section 6329 specifies the technical attributes of the system—wearable device, continuous 24/7 operation, tamper resistance, and broad locatability subject to technical and cost constraints—and requires courts to administer monitoring via written contracts with public or private entities. It also requires counties/municipalities to enter written agreements with qualified contract providers and to designate a responsible agency to respond to violations. Practically, this creates multiple procurement and oversight duties for local governments and sets minimum expectations vendors must meet to win contracts.
When courts must order monitoring and who pays
Section 6330 lists the triggering offenses that compel monitoring when the court issues a protective order and directs the court to require the alleged offender to wear the device and, except where the court finds inability to pay, to cover operating costs. The section also authorizes courts to order offenders to pay for a victim-facing app or receptor device if the victim consents. It preserves the court’s discretion to waive costs upon inability to pay and clarifies that monitoring remains until case disposition or further court order, which raises predictable questions about pretrial liberty and how long monitoring can persist.
Notification duty for monitoring operators
Section 6331 requires the operator of the monitoring system to notify the appropriate law enforcement employee and the emergency communications dispatch center if an offender violates a condition of the court order. That shifts responsibility for initial alerting to private or contracted operators and establishes a legal duty to transmit breach information to official responders—an operationally important point that creates expectations about uptime, alert accuracy, and communications protocols between private vendors and public safety agencies.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- High-risk survivors and protected parties — They receive real-time alerts when an offender breaches exclusion or proximity conditions, which can provide immediate warning and potentially reduce exposure to lethal violence.
- Courts and victim services programs — The statute gives judges a concrete, technology-based tool to manage risk and provides victim services organizations with another option to recommend for high-risk clients.
- Law enforcement and emergency dispatch — Agencies receive automated, real-time breach information that can improve situational awareness and speed response to potential threats.
- Monitoring vendors and technology providers — The requirement for county contracts and specific device attributes creates a market opportunity for companies able to meet the technical and contractual standards.
Who Bears the Cost
- Counties and municipalities — Responsible for executing contracts with providers, designating response agencies, and absorbing the administrative and operational burden of coordinating notifications and responses.
- Alleged offenders — The court may require them to pay monitoring and victim-device costs where the court finds ability to pay, exposing defendants to potentially significant supervision charges unless a waiver is granted.
- Local law enforcement and dispatch centers — They must respond to an increased volume of real-time alerts, which could require new protocols, staffing, and training without explicit state funding in the text.
- Contract service providers — Must meet the statute’s technical specifications, manage 24/7 operations, and carry legal duties to notify authorities, creating compliance and liability exposure.
- Public defense and indigent legal services — Will need to litigate ability‑to‑pay hearings and challenge cost orders, adding workload and potential litigation costs.
Key Issues
The Core Tension
The bill pits two legitimate objectives against each other: the urgent need to reduce lethal domestic violence through intrusive, continuous tracking versus the legal, privacy, and equity concerns raised by 24/7 monitoring—especially when imposed pretrial and when implementation quality will vary by county and vendor capability. Deciding which priority dominates is the central policy dilemma SB 871 forces local authorities and courts to confront.
SB 871 sets a clear operational direction but leaves multiple implementation details unresolved, creating trade-offs that counties and courts must manage. The statute requires devices be locatable in structures and vehicles ‘‘to the degree technically feasible in light of the associated costs,’’ which invites variability: urban jurisdictions with denser procurement markets might achieve better indoor accuracy than rural counties, producing inconsistent protection levels across the state.
The bill also places notification duties on private operators, yet it says nothing about data retention, access by prosecutors or defense counsel, the standards for accuracy or calibration, or how to handle false positives that could trigger unnecessary emergency responses.
The cost-shifting mechanism is another tension point. The bill allows courts to require alleged offenders to pay for monitoring but bars inability to pay from precluding monitoring and obliges courts to waive payments where a person lacks ability to pay.
That dual rule preserves access to monitoring while exposing judges to contested financial-assessment hearings and creates administrative complexity. Moreover, pushing costs to alleged offenders risks disparate impacts: poorer defendants may be monitored regardless of payment outcome, whereas better-resourced defendants can potentially cover costs more easily.
The statute also raises constitutional and pretrial liberty questions by authorizing continuous, around-the-clock tracking of individuals before disposition; the text does not set standards for judicial findings required to impose such intrusive measures, nor does it describe judicial oversight, audit trails, or remedies for device failures or erroneous alerts.
Finally, the bill will require counties to build procurement, contracting, and operational capacity quickly: selecting qualified vendors, negotiating uptime and notification SLAs, staffing response agencies, and integrating alert streams into 911/dispatch centers. Those tasks expose counties to procurement risk, vendor lock-in, and the need for clear contractual remedies.
Absent explicit funding, the program’s effectiveness will depend on local budgets and interagency cooperation, which could produce a patchwork of services and protections across California.
