| County | 1 unit | 2 units | 3 units | 4 units |
|---|---|---|---|---|
| Marin County | $1,249,125 | $1,599,375 | $1,933,200 | $2,402,625 |
| Solano County | $832,750 | $1,066,250 | $1,288,800 | $1,601,750 |
Marin County is above the 2026 national baseline of $832,750 for a one-unit home, and Solano County is at the baseline. These are conforming limits only. FHA limits are set by HUD, can be lower, and are not listed on this page: see FHA limits on the Loan limits page. Limits change each January, and the 2027 figures are expected in late November 2026. These are published limits, not an offer of any loan amount.
What a loan above the limit means here.
A loan above the county’s limit for the number of units in the home is a jumbo loan. It is the loan amount that counts, not the price of the home, so more money down can keep a loan at or under the limit. Jumbo loans are not sold to Fannie Mae or Freddie Mac, so each lender sets its own rules on income, savings and the property.
In Marin County, a loan above the national baseline of $832,750 and at or under the county’s limit for a one-unit home is a high-balance conforming loan. It is still a conforming loan, although some rules differ from the ones for smaller loans. Solano County follows the national baseline, so there is no high-balance range there.
The counties on this page do not share one limit. For a one-unit home the 2026 limit is $1,249,125 in Marin County and $832,750 in Solano County, so the same loan amount can be conforming in one county and a jumbo loan in another. Check which county the home is in.
The calculator shows where a loan amount falls, and the Loan limits page has every California county.
Homes in the North Bay include condos and townhouses as well as houses, some of them on hillsides or larger lots. With a condo, the lender reviews the building and its homeowners association as well as the buyer, and the association dues are added to the monthly housing cost when the lender works out what you can borrow. Condo financing is covered on the Loan options page.
Lenders require homeowners insurance, and proof of it is part of the lender’s file before a loan closes. In areas with wildfire risk it can take longer to arrange, so ask for insurance quotes early.
