Financing ADUs in National City

Constructing a detached ADU or performing a garage conversion costs between $125,000 and $300,000+ for higher-end builds. Smart financing is therefore essential for most National City homeowners planning an ADU addition.

The good news is that California now offers multiple affordable financing programs to support granny flat and guest house construction, including:

Low-Interest ADU Loans

Qualified National City applicants can apply to the California HCD for low-interest loans up to $100,000 or grants to fully or partially fund the construction of an ADU. We help navigate the state program.

Cash-Out Refinance

Many homeowners use cash-out refinancing to access their available home equity for major remodels or construction projects. The cashout amount can cover a portion or entirety of your ADU costs.

401(k) / Home Equity Loan

Some households tap their 401(k) savings or home equity to finance the construction of an ADU on their property. Retirement funds offer low fixed rates, while home equity borrowing also taps available funds at better terms than alternatives.
