Ventura County can be separated into two major parts, East County and West County, which are divided by the Conejo Grade. East County consists of all cities east of the Conejo Grade. Geographically East County is the end of the Santa Monica Mountains, in which the Conejo Valley is located, and where there is a considerable increase in elevation. Communities which are considered to be in the East County are Thousand Oaks, Newbury Park, Lake Sherwood, Hidden Valley, Santa Rosa Valley, part of Westlake Village, Oak Park, Moorpark, and Simi Valley. A majority of these communities are in the Conejo Valley. West County, which is everything west of the Conejo Grade, consists of communities such as Camarillo, Oxnard, Somis, Point Mugu, Port Hueneme, Ventura, Ojai, Santa Paula, and Fillmore. West County consists of some of the first developed cities in the county. The largest beach communities are located in West County on the coastline of the Channel Islands Harbor.
According to the U.S. Census Bureau, the county has a total area of 2,208 square miles, of which 1,843 square miles is land and 365 square miles (16.5%) is water.
Ventura County has a considerable range in climate because of differences in topography between one part of the county and another. Rainfall is limited in summer and crops have to be irrigated. The average annual temperature is near 60 °F at low elevations near the ocean, in the 50s over most of the northern two-thirds of the county, and less than 45 °F in the Topatopa Mountains.
Ventura County typically has limited housing inventory, making it a consistently expensive location in Southern California, where it is usually the third-most-expensive county behind Orange and Los Angeles counties. As of March 2018, the county was not on track to meet its state-mandated housing goals. Individual cities are responsible for meeting their assigned housing goals, while the county government is responsible for housing goals in unincorporated areas. Several affordable housing groups that are actively working on building housing for veterans and low income people have long waiting lists. Farmworker housing also has waiting lists though designated units continue to be built.
