Financing Your Build

Most homeowners finance ADU construction rather than paying cash. These are the common routes. Talk to a lender you choose; A-du does not arrange loans.

Illustrative payment on a $133,000 build~$1,154/mo

Illustration only, assuming a 20-year fixed loan at 8.5% APR on the estimated build-cost midpoint. Your rate, term, and eligibility depend on the lender and your finances. This is not an offer of credit; financing is provided by third-party lenders, subject to their approval.

Renovation & ADU construction loans

Lenders that underwrite on your home’s value after the ADU is built, often the best fit when current equity doesn’t cover the build.

Home equity (HELOC / home equity loan)

For owners with substantial equity, a line of credit against the home is typically the simplest and fastest route to fund construction.

Grants & public programs

California periodically funds ADU grant programs (e.g. the CalHFA ADU Grant for predevelopment costs, when funded). Worth checking before you borrow.
