What about the money I could make renting the ADU?

Rental income is a major benefit of having an ADU or JADU on your property – for many people, it provides flexibility in their budget or an opportunity to grow their savings. Generally, you cannot rent your ADU for less than 30 days at a time (e.g., AirBnB, Vrbo). The Santa Clara County ADU Calculator can help you estimate how much rental income could be generated by your new unit.
