How a HELOC Works in California: Rates, Terms and State Rules (2026)
A California HELOC is a revolving line of credit secured by your home, usually with a 10-year interest-only draw period followed by a 15- to 20-year repayment period. California credit unions commonly cap lines at 70% to 80% combined loan-to-value and $250,000 to $1,000,000, and many advertise a 12-month introductory rate before a variable rate tied to prime. Opening a HELOC does not trigger a Prop 13 reassessment, you get 3 business days to cancel on your primary home, and California still lets you deduct interest on up to $100,000 of home equity debt.
Key takeaways
- Typical California HELOC: 10-year draw, 15–20-year repayment, variable rate tied to prime.
- Credit unions: often 70%–80% CLTV and a 12-month teaser rate; they usually want tax returns from self-employed borrowers.
- A HELOC doesn't change ownership, so it doesn't reset your Prop 13 property tax base.
- California still allows an interest deduction on up to $100,000 of home equity debt, even where federal law doesn't.
California homeowners sit on a lot of equity, and most of them have a first mortgage rate they don't want to give up. A HELOC lets you borrow against that equity without touching the first loan. Here's how it works here, what the big California credit unions are offering, and where a broker fits.
How a HELOC works in California
- Draw period (usually 10 years): borrow, repay and borrow again up to your limit. Many lines require only interest on what you've used.
- Repayment period (usually 15 to 20 years): the line closes to new draws and you pay principal and interest. Your payment can jump at this point; plan for it.
- Rate: usually prime plus a margin, adjusted when prime moves, with a floor and a lifetime cap. Some lenders let you lock part of the balance at a fixed rate.
- How much: lenders cap your first mortgage plus the line at a percentage of value (CLTV). Example: $900,000 home × 80% = $720,000, minus a $450,000 first mortgage = up to a $270,000 line.
California credit union HELOCs vs. a broker
These are the terms three Southern California credit unions publish. Their rates, like ours, have been unusually volatile and change daily; call for today's quote. Check their sites before you decide.
| CU SoCal | Wescom Financial | Cal Coast CU | Save Financial (broker) | |
|---|---|---|---|---|
| Intro rate | 12-month fixed intro rate | 12-month intro rate | None listed | Depends on lender; we compare the full-term cost |
| After intro | Variable, prime-based, with a rate floor and cap | Variable, prime-based, with a rate floor and cap | Variable, prime-based, with a rate floor and cap | Prime plus margin, lender by lender |
| Max CLTV / line | 80% up to $250,000; 70% up to $500,000 | 80%; lines $15,000–$1,000,000 | Up to $250,000 on a primary home, 75% CLTV at that size | Up to 90% full-doc; 80%–85% bank statements; lines $50,000–$1,000,000 |
| Draw / repay | 10 years / 15 years | 10 years / 20 years | 10 years / 15 years | Usually 10-year draw |
| Fees noted | Appraisal fee; appraisal required above $250,000 | $75 annual fee (waived year one); $750–$2,500 if closed within 3 years | $5 membership; $0 out-of-pocket options | Varies; disclosed on your Loan Estimate |
| Property | Owner-occupied primary (CA or AZ) | California; intro rate on primary homes only | Primary residence (Southern California) | Primary, second homes and rentals (lender by lender) |
| Self-employed income | Business and personal tax returns | Standard documentation | Standard documentation | Tax returns, bank statements, P&L, 1099s, WVOE or assets |
If you have W-2 income, great credit and you only need $150,000 on your primary home, a credit union line is often hard to beat. If you're self-employed, need a bigger line, want more than 70% to 80% CLTV, or the property is a rental, that's where a broker earns its keep. More on that in best HELOC lenders in California.
Watch the teaser rate
A low 12-month intro rate sounds great. But on a $200,000 balance, every percentage point the rate rises when the teaser ends adds about $167 a month in interest (example math, not a quote). Compare lines on the rate you'll pay in year two and beyond, the margin over prime, the floor, the annual fee and any early-closure fee.
California rules that apply to a HELOC
Prop 13: no reassessment
Your property tax base resets on a change in ownership or new construction. Borrowing against your home isn't a change in ownership, so a HELOC doesn't reassess your property taxes. (Building an ADU with the money is new construction, and the new part can be assessed.) See the California Board of Equalization.
3 business days to cancel
On your primary home, federal law gives you a right of rescission: three business days after signing to cancel. The line opens after that. It doesn't apply to rentals.
California tax treatment
Under federal law, HELOC interest is deductible only when the money buys, builds or substantially improves the home that secures it. California never adopted that change: on your California return you can still deduct interest on up to $100,000 of home equity debt, whatever you used it for, along with acquisition debt up to $1,000,000. Ask your tax preparer how it applies to you; see IRS Publication 936 and the California Schedule CA instructions.
Licensing
Anyone arranging your HELOC should hold a California license through the DRE or DFPI and an NMLS number. Save Financial is NMLS #377740 and DRE #01875766.
HELOC requirements in California
- Credit: about 620 to 680 minimum depending on the lender; 720+ for the best terms.
- Equity: most lenders want you to keep 15% to 30% equity after the line.
- Debt-to-income: commonly 43% to 50%.
- Income: pay stubs and W-2s or tax returns at banks and credit unions; bank statements, P&L, 1099s, WVOE or assets through non-QM lenders. See HELOC requirements.
Self-employed in California?
This is most of my business. If the credit union asked for tax returns and the numbers didn't work, look at a no tax return HELOC or a bank statement HELOC. You keep your first mortgage either way.
HELOC or home equity loan?
A HELOC is a line you draw as needed at a variable rate; a home equity loan is a lump sum at a fixed rate. If you know the amount and want a fixed payment, look at a home equity loan. Side by side: HELOAN vs HELOC.
“For self-employed borrowers, the bank is often the wrong first stop. Business owners write off expenses, which is smart for taxes, but it lowers the income a bank is allowed to count, and many banks simply don't offer self-employed programs. When someone comes to us after a bank said no, I tell them not to give up. We look at what actually comes into their account, through bank statement, P&L and other programs most banks don't have, and very often we find a loan that fits.”
