San Diego's 2026 conforming limit: size the loan, not the house

What is the 2026 conforming loan limit in San Diego County?

In California, San Diego County's 2026 one-unit conforming limit is $1,104,000, according to FHFA's county list. A conforming loan fits the size and rules Fannie Mae and Freddie Mac set, so your lender can sell it to them. That line is about the loan. For you, it decides which kind of quote you're shopping.

San Diego sits well above the rest of the country. FHFA's 2026 baseline is $832,750 in most places, with a high-cost ceiling of $1,249,125. Anything larger than a county's limit is a jumbo loan. According to the Consumer Financial Protection Bureau (CFPB), jumbo loans may cost more to get than conforming ones.

Federal Housing Administration (FHA) loans hit the same number. In California, the U.S. Department of Housing and Urban Development (HUD) set San Diego County's 2026 FHA one-unit limit at $1,104,000. Most counties get far less: HUD's 2026 FHA one-unit limit is $541,287 in most counties and up to $1,249,125 in high-cost areas. So FHA doesn't give you extra room here.

Keep one thing straight. The limit is a size rule for which loans can be sold to those two companies. It isn't a lending decision, and it says nothing about whether you'll get approved.

The usual advice: stay under the line or pay for a jumbo

The usual view is fair. Once a loan goes past the conforming limit it's a jumbo, and the CFPB says jumbos may cost more to get than conforming loans.

Most buyers hear a simple rule: find your county's number and shop for houses priced so the loan stays under it. In California, San Diego's 2026 number is $1,104,000. Go over and you're shopping jumbo.

That advice has real logic behind it. Conforming loans follow one shared rulebook, so lenders can usually sell them easily. Above the line, each lender writes its own rules on credit, cash reserves and income.

The CFPB doesn't put a number on how much extra a jumbo costs. I won't guess either. The difference moves from lender to lender and file to file, and quotes are the only way to see it.

Where the usual view falls short is the word "price." It talks about the house. The limit is about the loan.

What I see: size the loan, not the house

In my view, the line that matters is your loan amount. The price of the house matters less, and a self-employed buyer has more ways to stay under the line or qualify above it than one bank will show them.

Start with where San Diego's line sits. FHFA's 2026 national baseline is $832,750, in California San Diego County's limit is $1,104,000, and the high-cost ceiling is $1,249,125. So the county sits closer to the ceiling than to the baseline.

If you're shopping $900K to $1.3M, your price range straddles the line. Your loan is the price minus the cash you bring. More cash down can pull a loan under the line on a home that would otherwise need a jumbo. So ask each lender to price the home both ways: at the line, and above it.

I'm a broker, so I shop one file across a network of wholesale lenders instead of one bank's rules. We also close bank-statement loans, which show your income from business bank deposits instead of tax returns. Different lenders want different deals.

One file of mine shows why that matters. A self-employed contractor came to me after his bank turned him down. His returns showed about half of what he really earned, because his accountant wrote off as much as he legally could. We used twelve months of business bank statements, found a lender that liked the deal, and he closed at a payment he was comfortable with.

That's one file, not a rule about approvals or timelines. What it changes is the order of your choices: if you think your returns rule you out, compare ways to document income before you shrink your house budget. I explain how that works in my guide to bank-statement loans for self-employed buyers.

Whether to report more income on future returns is a tax-strategy question for your certified public accountant (CPA), not for me.

When the 2026 line won't help you

The conforming line matters less if your loan is FHA or VA, or if you'd use a bank-statement loan, because each of those follows its own rules.

FHA buyers here face the same number. In California, HUD's 2026 FHA one-unit limit for San Diego County is $1,104,000, and FHA's own rules cover the rest of the file.

VA loans work differently. The U.S. Department of Veterans Affairs (VA) sets no loan limit for borrowers with full entitlement, which is the backing VA puts behind your loan. With only remaining entitlement, VA figures it from the county limit, minus what you've already used. With a down payment, you may be able to borrow above the county limit, though your lender still has to approve you.

Bank-statement loans usually sit outside Fannie Mae and Freddie Mac's rules altogether. We close them, and the lender's own guidelines, not the county number, decide the loan.

Timing can change things too. The Federal Housing Finance Agency publishes new limits each year, so if you close in a later year, check that year's figure.

What the 2026 limit means for your purchase

In California, if your San Diego loan can sit at or under $1,104,000 and you can document your income, start with a conforming quote (2026). Then compare any jumbo or bank-statement quote on the same day, before you settle on a price.

• Conforming, under the line: fits when your tax returns support the loan and your cash keeps it at or below the county limit.
• Jumbo, above the line: for when the loan has to go higher and your returns back it up.
• Bank-statement loan: fits when your returns show less than you earn, on either side of the line.
• VA loan: with full entitlement, the county line doesn't cap it.

Same-day quotes keep rate moves from muddying the comparison. Then read the loan estimates line by line, because the lowest rate isn't always the loan that costs you least.

To show how a rate becomes a monthly payment, the sample below uses a small loan and a market average rate. It isn't a San Diego jumbo figure.

Example: a $400,000 30-year fixed loan at 6.15% (6.221% APR) with 20% down ($100,000) on a $500,000 home has 360 monthly payments of $2,436.91 in principal and interest. The APR assumes 0.75 discount points ($3,000, the median paid by 2023 home buyers who paid points, according to the CFPB) and no other lender fees. Taxes and insurance are not included, so the actual payment will be higher. The rate is the market average for December 31, 2025 from Freddie Mac Primary Mortgage Market Survey; yours depends on your credit, loan and property.

My decision rule: if your loan can stay at or under $1,104,000 and your documented income supports it, get a conforming quote first. If your returns run low or the loan must go higher, compare a bank-statement or jumbo quote against it the same day. With full VA entitlement, the conforming line doesn't cap your loan. To see what the payment actually looks like at a few loan sizes, run your numbers in the calculator on this page.

The calculator gives an estimate with no credit pull, not an approval or a rate quote. No limit table can tell you whether a lender will approve your file; only underwriting decides that.

How I know this

I've done this work for 21 years at Rate Rebel (NMLS #282828) in San Diego. As a broker, I shop one file across wholesale lenders, and we close bank-statement loans retail banks turn away. The contractor's file is why I tell self-employed buyers to compare income documentation before cutting their price range. The limits come from FHFA and HUD; the jumbo cost point is the CFPB's.
