Can you build an ADU in Sloan, NY?

Residential District - The rear yard is a three-way test and the 25 ft shown is only its floor: it must equal 25% of the lot depth, but never less than 25 ft or a distance equal to the height of the principal building, whichever of the three is greatest.

• A corner lot must be at least 70 ft wide rather than 60
• A duplex needs at least 9,000 sq ft rather than 7,200, and 70 ft of width on an interior lot or 80 on a corner
• A garage or accessory building stops at 15 ft, may come no closer than three feet to a side or rear lot line, and must stand at least ten feet from any other structure so emergency vehicles can pass

Multifamily Apartment District - Side yards are percentages and the figures shown are their ceilings: each side must equal 10% of the lot width but need not exceed 10 ft, and the two together 25% of the lot width but need not exceed 25 ft, so a lot under 100 ft wide owes less.

• The figures shown are for a single house, which takes the single-family district's standards unchanged; this district's own numbers start at three dwelling units
• The rear yard must equal 25% of the lot depth, but never less than 25 ft or the height of the principal building, whichever of the three is greatest
• A principal building that is not a dwelling takes 15 ft or half its own height, whichever is greater
• Two principal buildings on one lot must stand 30 ft apart or the average of their wall heights, whichever is greater
• Any part of a building that is not a dwelling and rises above 30 ft is capped at twice the number of feet provided in the yard facing that wall, so a 40 ft wall needs 20 ft of yard
• A garage or accessory building stops at 15 ft, may come no closer than three feet to a side or rear lot line, and must stand at least ten feet from any other structure
