What the Warwick code says

In R, LO and CB one accessory apartment is a conditional use, only in a structure that existed before Local Law No. 4 of 1984 took effect; MR-SC does not permit one. The owner must live in one unit and have lived on the premises for at least 12 consecutive months before applying.

Conditions the code attaches:

The permit becomes void if the owner has another place of residence for more than six (6) months, and the premises revert to their original permitted use.
The unit must be 400 to 800 square feet, excluding porches and basements, and never larger than the primary residence; a unit inside the house may not reduce it below 1,000 square feet.
The unit may have no more than one bedroom, and each dwelling unit needs its own private bathroom and kitchen.
A garage or other detached building can hold the unit, provided it also existed before Local Law No. 4 of 1984 took effect.
A guesthouse or servant or caretaker dwelling is also a conditional use in R, LO and CB.
Parking may not be in the front yard or on the driveway forward of the front building line.

ADUs vs. short-term rentals in Warwick

Short-term rentals allowed with local rules for Village of Warwick. Renting a home short term in the Village of Warwick requires a permit under Chapter 115, Short-Term Rentals, and a rental the owner does not occupy also needs a special use permit. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
