San Diego County Conforming Loan Limits 2026
Quick answer: For 2026, the FHFA high-cost conforming limit for a 1-unit home in San Diego County is $1,104,000. The national baseline is $832,750. Amounts between those two figures are high-balance conforming. Anything above $1,104,000 is generally jumbo. The test is loan amount, not list price.
San Diego buyers hear "jumbo" as soon as a price tag crosses a million dollars. That is the wrong trigger. The Federal Housing Finance Agency (FHFA) sets county conforming loan limits each year for loans Fannie Mae and Freddie Mac can buy. In a high-cost county like ours, that line is higher than the rest of the country. Left Coast Leaders, Inc. (NMLS #2394495) prices both sides of the line so you are not shopping jumbo guidelines when a high-balance conforming loan still fits.
The 2026 San Diego County numbers
FHFA announced 2026 limits in late 2025. The national 1-unit baseline rose to $832,750. High-cost counties can go as high as 150% of that baseline, which is $1,249,125. San Diego County sits in the high-cost band, but not at the national ceiling.
| Property | Baseline (standard conforming) | San Diego County high-cost limit |
|---|---|---|
| 1-unit (house, condo, townhome) | $832,750 | $1,104,000 |
| 2-unit | $1,066,250 | $1,413,350 |
| 3-unit | $1,288,800 | $1,708,400 |
| 4-unit | $1,601,750 | $2,123,100 |
Confirm the current FHFA county table before you write an offer. Limits are set by county, not by neighborhood, so the same 1-unit cap applies in El Cajon, La Jolla, Downtown San Diego, and unincorporated county areas.
Baseline vs high-balance vs jumbo
For a 1-unit San Diego County purchase in 2026, think in three buckets:
- Loan amount up to $832,750: standard conforming.
- $832,751 through $1,104,000: high-balance conforming. Still eligible for Fannie Mae or Freddie Mac, with pricing and overlays that are often a notch tighter than baseline.
- Above $1,104,000: jumbo (non-conforming). See our San Diego jumbo loan guide for credit, reserve, and documentation expectations.
High-balance is the bucket most San Diego buyers miss. A Clairemont or North Park purchase can look "expensive" and still close as high-balance conforming. A coastal Del Mar or Point Loma purchase more often lands jumbo, but only if the loan amount (not the price) clears $1,104,000.
Loan amount, not purchase price
This is the math that changes offers. Loan amount is purchase price minus down payment and any other principal reductions at closing.
- $1,200,000 purchase with 20% down ($240,000) is a $960,000 loan. That is high-balance conforming in San Diego County, not jumbo.
- $1,150,000 purchase with 5% down is a $1,092,500 loan. Still under $1,104,000, so it can still be high-balance conforming if the rest of the file qualifies.
- $1,250,000 purchase with 10% down is a $1,125,000 loan. That is jumbo.
If you are near the line, changing down payment by a small amount can move you from jumbo overlays into high-balance conforming. That can mean different reserve requirements, different maximum DTI, and different pricing. Run both paths before you lock a strategy. Our affordability calculator and payment calculator help you see the monthly number. Pre-approval is what tells you which bucket the loan actually sits in.
How this interacts with FHA, VA, and conventional
The FHFA figure is the conventional conforming cap. Other programs have their own rules:
- Conventional loans: the $1,104,000 1-unit San Diego County limit is the line between high-balance conforming and jumbo.
- FHA: HUD publishes county FHA forward limits separately. In high-cost counties they often match the FHFA high-cost figure, but you still verify the current HUD county table for the property type.
- VA: borrowers with full entitlement are not capped by the old county VA limit the way they used to be. Partial entitlement and lender overlays still matter, so we check remaining entitlement before assuming a large VA loan is automatic.
Condo financing adds a second filter. Even when the loan amount is conforming, the project has to be eligible. That comes up often Downtown and in coastal stacked buildings. See condo mortgages in San Diego.
What to do if you are shopping near the limit
If your target neighborhoods include La Jolla, coastal Point Loma, Del Mar, Carlsbad, or higher-priced pockets of North County, get a pre-approval that states the program, the max loan amount, and whether the file is baseline, high-balance, or jumbo. Sellers in those areas have seen files stall when the buyer assumed "conventional" without checking the cap.
If you are looking in El Cajon, Santee, Chula Vista, or many interior San Diego neighborhoods, you may never hit jumbo. Still know the number. A duplex or house-hack can use the 2- to 4-unit limits, which are higher, and that can keep a small income property in conforming territory.
Amir Nurani (NMLS #197458) will price the conforming path and the jumbo path on the same credit and income file when you are close. That is faster than finding out under contract that the loan amount crossed a line.
