California rules that affect your HELOC

California is a community property state, so a spouse usually signs the HELOC documents even if not on the loan.
A HELOC doesn't trigger a Proposition 13 reassessment; your property tax base stays the same.
San Diego County's 2026 conforming loan limit is $1,104,000 for a one-unit home. It caps a conventional cash-out refinance, not a HELOC. FHFA.
Every lender requires proof of homeowners insurance before closing. With insurers pulling back in fire-prone parts of California, line up coverage before you apply.
