Can you build an ADU in Pleasant Valley, NY?

Conservation, Rural Agricultural, Rural Residential, Lower Density Residential, Medium Density Residential — The schedule's acreage column is headed "Average density (recommended lot size — for calculation of number of lots)", and its own note says so in terms: it is used to work out how many lots a project may have, and the lot sizes themselves can vary. It is not a minimum lot size, so it is carried as land per dwelling unit and no lot minimum is recorded. Lots must still satisfy Dutchess County Department of Health standards. Coverage is maximum IMPERVIOUS coverage, not building footprint. Minimum road frontage is 50 ft. The front yard is measured from the property line, or from the assumed property edge where the property line is the road centre line. Where a lot line abuts land in a residential district, the more restrictive setback of the two districts governs. A nonresidential establishment may not exceed 4,000 sq ft of building footprint; agricultural and agricultural-related structures are exempt.

Special Flood Hazard — NEW RESIDENTIAL STRUCTURES ARE PROHIBITED in the Special Flood Hazard District. The schedule publishes no figure of its own for it: allowed uses, accessory buildings and additions must meet the MOST RESTRICTIVE area and bulk requirements of any adjoining zoning district, and the floodplain regulations at § 98-29. Nothing is recorded here because the governing standard depends on which district adjoins the parcel.
