Hiring and costs

How do I choose a private investigator?

Choose an investigator who is licensed in California and insured. It is a crime to practice private investigation in California without a license, and the Bureau of Security and Investigative Services (BSIS) lets you verify a license on its website. The right investigator is experienced in both law enforcement and the private sector, explains the process clearly, and makes you comfortable confiding in them. Billing should be straightforward, and all deliverables should be spelled out in advance.

How much do you charge for your services?

Our fees vary with the type of service and its complexity. Our billing structure is straightforward and is discussed during your free consultation. Call (415) 307-1012 and we can provide a quote at that time.

Confidentiality and the law

Is my information kept confidential?

Yes. As licensed private investigators (CA PI 189051), we are ethically bound to provide the utmost confidentiality. Everything you tell us and everything we uncover stays with us unless you authorize us to share it.

Is all this legal?

Yes. Our services are legal for us to perform and legal for you to hire. We conduct every investigation in full compliance with the law, which also protects the value of the evidence we collect.

Can an investigator put a GPS tracker on someone’s car?

Generally not. California Penal Code section 637.7 prohibits using an electronic tracking device to determine the location or movement of a person, with exceptions such as the registered owner of the vehicle consenting. We do not use methods that put you or your case at legal risk. Ask us about lawful alternatives, such as surveillance by trained investigators.

Can what you find be used in court?

Evidence gathered lawfully and documented properly can support legal matters, and we provide professional reports upon request. Whether it is admissible in a particular case is decided by the court, so we recommend working with your attorney.

How investigations work

Do I need an investigator if I suspect my significant other of infidelity?

The decision to investigate infidelity is personal. Many of our clients were tired of the uncertainty and no longer wanted to be left guessing. When faced with photographic and video evidence, they received the peace of mind they were seeking and moved forward with the best possible knowledge.

What does surveillance include?

We collect a mix of photo and video evidence using the best equipment for the situation, keep you updated on developments, and provide a professional report upon request.

Can you find someone who does not want to be found?

Often, yes. We use a variety of public and private databases and field work to locate people, including difficult subjects for service of process. Contact us with what you know and we will tell you what is realistic.

What is a bug sweep?

A bug sweep, also called Technical Surveillance Countermeasures (TSCM), is a search for hidden cameras, GPS trackers, key loggers, listening devices and location tracking apps. If you think you are being monitored, call us from a phone you trust.

Do you work with attorneys, businesses and insurance companies?

Yes. We support attorneys with witness location, process service, background and asset research, and we help businesses and insurers with employee misconduct, workers’ compensation, personal injury and claims investigations. See our Services page for the full list.

What if I need something not listed on your site?

Call us. People are unique and so are their needs. We will work with you to tailor an investigative plan to your situation.
