What Is a Jumbo Loan in California? (2025 Guide to Limits, Rates & Approval)

Understanding Jumbo Loans & Conforming Limits

A jumbo loan is any mortgage amount that exceeds the conforming loan limits set by the Federal Housing Finance Agency (FHFA). These limits determine which loans can be purchased or guaranteed by Fannie Mae and Freddie Mac

2025 Baseline Conforming Loan Limit:

• $806,500 for a single-unit home in most U.S. counties

High-Cost California Counties:

• In expensive counties—such as Alameda, Contra Costa, Los Angeles, Marin, Orange, San Francisco, San Mateo, Santa Clara, and San Benito—the limit is set at $1,209,750 for single-family homes in 2025

If your loan request exceeds the applicable conforming limit, you'll need a jumbo loan.
