Financing an ADU should not be the last question. It should be part of the early planning.

A homeowner in Jamaica, Queens contacted me after seeing that her property appeared to be a strong candidate for an ADU. She had a deep lot, a semi-detached home, and an existing garage in the rear yard. Her first idea was to tear down the garage and build a brand-new detached backyard unit.

That may sound simple, but detached ADUs are often among the more expensive options. You are not just "renovating a room." You may be creating a small new building — with foundation work, structure, utilities, sewer and water connections, heating and cooling, fire protection, insulation, and exterior work.

When we discussed financing, she said she could probably access about $100,000 through savings and a home equity line. That was useful information because it changed the conversation. A new detached unit might cost far more than that — especially with professional fees and contingency. But a more modest conversion, or a phased approach, might be more realistic.

This is why financing should be discussed before design. If you ask an architect to design the dream version first, you may end up with plans you cannot afford to build.

A better first step is to ask:

✓What can I responsibly spend?

✓What can I borrow?

✓What rent is realistic?

Then match the ADU type to the budget.

Budget First, Design Second

Most homeowners assume an ADU gets financed like a renovation, but the money question is really about which asset the lender is underwriting. Cash, home equity, construction loans, and renovation mortgages each carry different costs and timelines, and the one that fits depends more on your equity position than on the project itself.

Can your ADU actually make money?

An ADU can create rental income, but the rent number alone won't tell you whether the project works. The smarter question compares likely rent against total project and ownership cost, and the gap between what a homeowner imagines and what it really takes can be larger than expected.

The five main ADU types — and which one suits your property.

Most homeowners begin with one question: "Can I add an apartment?" A better question is: "Which type of ADU best fits my property?"

There are five common ADU types to consider.
