Costa Mesa is a city of about 111,000 people in Orange County, and it is part of our regular coverage across Southern California.

Costa Mesa Surveillance Investigations: Our Specialty
As a Costa Mesa private investigator, surveillance is the core of what we do. We document activity legally, discreetly, and in a way that holds up in court.
Mobile Surveillance
We follow the subject by vehicle through Costa Mesa and beyond, keeping distance and cover so they never know we are there.
Static Surveillance
We hold position at the locations that matter to your case and record activity with time-stamped video.
Two-Investigator Teams
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
Commutes in Costa Mesa average about 22 minutes, so routines tend to stay local — which helps when we are documenting a pattern over several days.
