The “California Historical Resources Inventory Database” (CHRID) is a searchable, interactive database of historic properties that contains information about every designated historic property and district in the city and many other properties and districts that have been identified in recent historic resources surveys including the city’s most recent citywide survey of buildings constructed in the Mid-twentieth Century (1935 – 1965). The database was developed by the City of Ontario and a company called CFWebtools with the intent of being used by cities throughout California.
