What the Rhinebeck code says

An accessory dwelling unit needs a Planning Board special permit in the VC, R and MP districts and is not allowed in GB or F. The owner must live in one of the two units on the lot for at least six months of the year.

Conditions the code attaches:

The unit must be at least 400 sq ft and no more than 25% of the primary dwelling, up to 750 sq ft.
No more than one ADU per single-family home, and it counts toward maximum lot coverage.
The unit must have complete sanitary, kitchen and sleeping facilities for year-round use by one family, and be secondary to and architecturally compatible with the principal dwelling.
Off-street parking is required for any increase in vehicles beyond what § 120-16 requires.
The ADU cannot be subdivided onto its own lot unless each resulting lot conforms on its own.
The ADU itself may be rented; the owner-occupancy rule covers the lot, not who lives in the unit.

What the Rhinebeck code indicates by district

The table below shows how each district treats ADUs, alongside the lot and setback standards that govern a second unit. District boundaries and conditions vary, so treat this as a starting point and confirm the district that applies to your parcel.

ADUs vs. short-term rentals in Rhinebeck

Short-term rentals allowed with local rules for Village of Rhinebeck. Short-term rentals need an annual permit and Planning Board approval under § 120-17.1, and only an owner-occupied primary residence qualifies. The village issues at most 15 permits a year. 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.
