The City of Paso Robles has maps of subdivisions done within the City limits, which will show the location of any property corners that were set at the time of the subdivision. Assessor parcel maps provide general information regarding property lines. Assessor Parcel Maps can be viewed online on the SLO County Assessor's Office website, or at City Hall at 1000 Spring Street. Property corners are often lost or buried and can be difficult to locate. When an accurate location of a property line is necessary, the City recommends that the property owner hire a professional licensed to perform land survey work.
