Jumbo Loan Limits in California for 2025
What is the jumbo loan limit in California? In 2025, any single-unit mortgage above $1,149,825 is considered jumbo in most of the state, but the exact threshold shifts by county. The baseline conforming limit set by the Federal Housing Finance Agency is $1,149,825 for one-unit properties in high-cost areas; loans above that amount fall into the non-conforming, or jumbo, category. Because California home prices routinely exceed the national baseline, nearly every county in the state is classified as a high-cost area.

How the 2025 Limits Are Determined
The FHFA sets conforming loan limits annually based on the average home price in an area. Counties where the median home price exceeds the national baseline qualify for higher limits. In California, virtually every county clears that bar, which is why the jumbo threshold statewide starts at $1,149,825 for a one-unit property. For two-unit properties the ceiling rises to $1,481,225; for three-unit properties it is $1,802,025; and for four-unit properties it reaches $2,207,300. Any loan amount above these figures is classified as jumbo in the respective property type.
County-Level Jumbo Thresholds in California
Because the conforming ceiling is the same across nearly all California counties in 2025, the jumbo limit does not vary much at the county level for single-family homes. The one-unit jumbo threshold is $1,149,825 statewide. What differs is the local median price and the availability of conforming loans, which affects how often buyers actually encounter jumbo products. The following table summarizes the 2025 conforming ceilings and the corresponding jumbo threshold for a one-unit home in California.
| Property Type | 2025 Conforming Ceiling | When It Becomes Jumbo |
|---|---|---|
| One-unit | $1,149,825 | Above $1,149,825 |
| Two-unit | $1,481,225 | Above $1,481,225 |
| Three-unit | $1,802,025 | Above $1,802,025 |
| Four-unit | $2,207,300 | Above $2,207,300 |
Why California Loan Limits Are Higher Than the National Average
The national conforming loan limit for one-unit homes in 2025 is $806,500 in most areas. California's limit is roughly $343,000 higher because the FHFA designates the entire state as a high-cost area. In places like San Francisco, San Mateo, and Santa Clara counties, median home prices far outpace the baseline, so jumbo loans are the norm rather than the exception. Buyers in these markets regularly finance amounts well above $1,149,825, which means they face jumbo underwriting standards, higher down payment expectations, and stricter reserve requirements.
What Jumbo Status Means for Borrowers
A loan is classified as jumbo once it exceeds the conforming ceiling for the property type and county. That classification triggers different underwriting guidelines. Lenders typically require higher credit scores, lower debt-to-income ratios, and larger cash reserves. Interest rates on jumbo loans may also be slightly higher than on conforming loans, though spreads have narrowed in recent years. Because the limit is uniform across nearly all of California for 2025, the practical difference between counties is less about the threshold itself and more about local home prices and lender appetite for non-conforming risk.
