The published evidence provides the starting point: Walnut Creek, CA is connected to Contra Costa County for this 2026 source comparison. In practical terms, the published one-unit conforming limit is $1,249,125, while the published one-unit FHA limit is $1,249,125. Those figures organize different program categories; $1,249,125 is not a conventional loan offer, and $1,249,125 is not an FHA eligibility finding. For Walnut Creek, CA, starting with Contra Costa County keeps the limits attached to the county or county-equivalent area used in the official files. Borrowers in Walnut Creek, CA still need to confirm the selected property's location and legal unit count, because the relevant Contra Costa County row follows the property rather than the city label or mailing address alone. Around Walnut Creek, CA, mailing cities and ZIP codes can cross county boundaries, so the official property jurisdiction should be verified instead of inferred from a familiar place name. Keep Contra Costa County as Walnut Creek, CA's confirmed county row before comparing the $1,249,125 and $1,249,125 program boundaries.
As local context for Walnut Creek, CA, Contra Costa County's conforming limit rises from $1,249,125 for one unit to $2,402,625 for four units, while the FHA figures move from $1,249,125 to $2,402,625. For borrower planning, the higher $2,402,625 and $2,402,625 amounts apply to the published four-unit category; they do not apply to a one-unit home merely because a borrower wants a larger loan.
