What San Diego County’s 2026 limit means for buyers
At $1,104,000, San Diego County’s one-unit conforming limit runs $271,250 — about 33% — above the $832,750 baseline that applies in standard-cost counties, reflecting San Diego County’s elevated local home values.
In practice, that means a buyer here can finance a home up to $1,104,000 with a conforming conventional loan — at conforming rates and guidelines — where a buyer in a $832,750 county would already need a pricier jumbo loan. Cross above $1,104,000 and San Diego County buyers enter jumbo territory too: expect higher credit and reserve requirements and lender-specific underwriting.
FHA buyers in San Diego County get the same $1,104,000 one-unit ceiling — well above the $541,287 FHA floor used in low-cost areas. And because the multi-unit limits reach $1,413,350 for a duplex and $2,123,100 for a fourplex, a small multi-family in San Diego County can often still be financed conventionally — an edge for house-hackers and owner-occupant investors who can count projected rent toward qualifying.
Bottom line: in San Diego County the conforming/jumbo dividing line is $1,104,000, not the $832,750 you’d see nationally — so a higher-priced home here may still qualify for a conventional loan. Confirm your exact figure below before you shop, since limits reset every January.
