What the Sloatsburg code says

Sloatsburg's zoning has no accessory dwelling unit provision, and an accessory apartment is not permitted in R-80, R-40, R-15, R-10, MU-1, MU-2, VC-1, VC-3 or O. In LIO the rule is not confirmed.

Conditions the code attaches:

Accessory buildings are limited to uses clearly incidental and subordinate to the principal use.
In VC-3, two-family dwellings in existence on the effective date can be repaired and replaced in size and kind, but may not be expanded in size (§ 402-20.1).
Bed-and-breakfasts are permitted in VC-3 without a special permit, subject to Planning Board consideration of the § 402-37D criteria at site plan.
A bed-and-breakfast must be occupied year-round as the principal residence of the owner, and boarders or renters and home occupations are prohibited in that use.
In VC-3, mixed residential and nonresidential uses are permitted under § 402-20.1 where the nonresidential use is otherwise allowed, and each dwelling needs at least 900 square feet of habitable area.
For the district that applies to a specific property, confirm the accessory use rules with the building department at (845) 753-2727.

What the Sloatsburg 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.

District	Min lot	Setbacks F / S / R	Max height	ADU
Residential R-80	1.84 ac	50 / 40 / 75 ft	35 ft	No
Residential R-40	0.92 ac	50 / 40 / 75 ft	35 ft	No
Residential R-15	0.34 ac	35 / 15 / 35 ft	35 ft	No
Residential R-10	0.23 ac	35 / 15 / 35 ft	35 ft	No
Mixed Use 1	0.23 ac	35 / 15 / 35 ft	35 ft	No
Mixed Use 2	0.23 ac	35 / 15 / 35 ft	35 ft	No
Village Center 1	0.11 ac	70 / 10 / 30 ft	35 ft	No
Village Center 3	0.11 ac	20 / 0 / 10 ft	35 ft	No
Office	0.23 ac	35 / 25 / 35 ft	30 ft	No
Light Industrial/Office	0.92 ac	100 / 50 / 50 ft	30 ft	—

Residential R-80 - At the floor area ratio of 0.075, a six-thousand-square-foot house needs eighty thousand square feet of land, exactly the lot minimum.

The 300 ft minimum lot depth is a separate requirement from the 200 ft lot width, and the lot must meet both.

Residential R-40 - On a lot of the 150 ft minimum width, the 40 ft side setbacks on each side leave seventy feet for the building.

The 200 ft minimum lot depth is a separate requirement from the lot width, and the lot must meet both.

Village Center 1 - The side setback may be reduced to zero where an existing building is attached to another existing building along a property line, which makes a continuous street wall possible.

The 70 ft front setback applies on a lot as small as five thousand square feet, which pushes the building toward the back of the parcel.

Village Center 3 - The front setback depends on the street the lot faces: 20 ft on Route 17, and 10 ft on Mill Street or Municipal Plaza.

A country inn center is a different row entirely: 2 acres rather than five thousand square feet, in exchange for 70% coverage, a 0.70 floor area ratio and three storeys.
Its width, depth and yards do not change, and the schedule does not say whether it needs a discretionary approval, so check the use table before relying on it.
No side setback is required on one side, but the two sides must add to at least 10 ft, so one side may carry all of it.

Office - On a lot of the 75 ft minimum width, the 25 ft side setbacks on each side leave twenty-five feet for the building.

The 100 ft minimum lot depth is a separate requirement from the lot width, and the lot must meet both.

Light Industrial/Office - On a lot of the 150 ft minimum width, the 50 ft side setbacks on each side leave fifty feet for the building.

The 250 ft minimum lot depth is a separate requirement from the lot width, and the lot must meet both.

ADUs vs. short-term rentals in Sloatsburg

Short-term-rental status not confirmed for Village of Sloatsburg. Short-term rental rules in the Village of Sloatsburg are not confirmed. The zoning chapter does not address transient rental, and that silence is not permission, so confirm with the Building Department before listing a property. 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.
