Jumbo loan limits in California range from $417,000 to over $600,000. The median value of a home in California is more than double the median values of homes for United States as a whole, even though the median income is only slightly higher.

The highest limit before a loan is considered jumbo in California is $625,500 in counties such as Los Angeles, Orange, San Francisco and Santa Barbara.
