Only a Professional Land Surveyor (or Civil Engineer registered prior to 1982) licensed by the State Board of Professional Engineers and Land Surveyors is legally authorized to practice land surveying in the State of California.  A survey may be required to help you determine the boundaries, features, or encroachments on your land in order to purchase, develop, satisfy local code or building requirements, or to settle a dispute over a property line with a neighboring property owner. The services of a Land Surveyor today will often cost you less time and money than the cost of relocating improvements or defending a lawsuit later.  

Be a smart consumer………
The California Board for Professional Engineers and Land Surveyors (CBPELS) allows you to search for your surveyor to confirm the status of his or her professional license.
