What the Pleasantville code says

An accessory apartment is allowed by special permit on a one-family lot in RRR, RR, R and R-1, including a lot nonconforming as to bulk requirements, and the owner must live in one of the units as a principal residence (§§ 185-31A, 185-32A, 185-32B).

Conditions the code attaches:

The Village issues no more than 50 accessory apartment special permits; legalized preexisting units and other legally existing apartments do not count against that limit (§ 185-33A).
The Planning Commission must deny a permit if three other such permits or approvals have already been issued within a 500-foot radius of the lot's property lines (§ 185-33B).
The apartment must be in the principal dwelling, in a portion that has existed at least 10 years before the application, and garage space may not be used (§ 185-32D).
At least 250 sq ft of livable floor area and no more than 25% of the dwelling's gross floor area, not counting roof, cellar, garage, home-occupation or under-10-year space; at most two bedrooms.
Parking follows Schedule VII of § 185-36, and the Planning Commission may not allow it in the required front yard.
Westchester County Department of Health approval of water supply and sewage disposal is needed where the Building Inspector determines it applies.
