State Laws A practical guide to computer monitoring law across the United States
Computer Monitoring Laws in the United States
Monitoring software is legal across the United States when it is used on devices you own, on computers used by your minor children, or on company equipment with notice and consent. This page explains the federal framework, the state consent rules and the workplace requirements that matter most.
The federal framework
Two federal statutes set the baseline for computer monitoring law:
One-party vs. two-party consent states
Most states follow the one-party consent rule for recording private communications: at least one person involved in the communication must consent. A smaller group of states requires all parties to consent. The states generally classified as all-party (two-party) consent states are:
| Rule | States |
|---|---|
| All-party (two-party) consent | California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania, Washington |
| One-party consent (most others) | Texas, New York, Ohio, Georgia, Colorado, Arizona, and the remaining states |
Note that these rules concern recording communications. Logging activity on a computer you own - such as websites visited or applications used - is generally treated differently from intercepting a live communication. State law continues to evolve, so always verify the current rule in your state.
Workplace monitoring law
Employers may monitor company-owned computers, but the safe standard everywhere is advance written notice plus a published policy. States with specific workplace-notification requirements include:
| State | Requirement |
|---|---|
| California | Employers must give written notice that monitoring may occur (Cal. Labor Code 435). |
| Connecticut | Employers must give prior written notice of electronic monitoring (Conn. Gen. Stat. 31-48d). |
| Delaware | Employers must provide prior written notice of electronic monitoring (Del. Code 19-705). |
Even where no statute exists, published notice and a signed acknowledgement are the strongest protection for any monitoring program.
Parental monitoring of minors
Because parents own the computer, parental monitoring of a minor child's activity on the family device is lawful throughout the United States. Best practice is to be transparent with your children about why the computer is monitored. For children under 13, review the Children's Online Privacy Protection Act (COPPA) if your monitoring collects personal information.

Frequently asked questions
One-party consent means a private communication may be recorded when at least one person involved consents. Two-party (all-party) consent means everyone involved must consent. The rule that applies depends on the state where the recording happens.
Yes. Employers should provide advance written notice and a clear monitoring policy. California, Connecticut and Delaware specifically require written notification to employees before monitoring begins.
In practice, parents may monitor computers they own that are used by their minor children in all US states, because the parent owns the device. Some states have specific parental-monitoring statutes; COPPA also applies to children under 13.
No state makes monitoring your own device illegal. The restrictions concern recording private communications without consent and accessing computers without authorization - which is why consent and device ownership matter.
