Map Checking Services

The Ventura County Surveyor’s Office is responsible for checking Subdivision Maps (Tract Maps and Parcel Maps) within the unincorporated areas of Ventura County. We also check Records of Survey and Corner Records within both unincorporated territory and all incorporated cities.  A map check examines boundary determination, mapping standards, technical correctness, and compliance with state law and local ordinances. The Ventura County Surveyor’s Office also provides Subdivision Map Checking Services for the following incorporated cities within the county: Camarillo, Fillmore, Oxnard, Port Hueneme, San Buenaventura, Santa Paula, Simi Valley and Thousand Oaks.
