(A) The Zero Lot Line District is intended to promote more efficient use of land as compared with typical single-family residential development and to introduce a type of housing design that is more affordably priced. The use of design principles allows for the integration and relation of the internal and external living areas by placing the dwelling units against one (1) or more of the property lines thus permitting outdoor spaces to be grouped and utilized at a larger scale.
(B) Uses permitted by right include:
(1) Single-family attached and single-family detached dwellings;
(2) Public recreational facility including neighborhood playground; and
(3) Residential care facility.
(C) Permitted accessory uses and structures include:
(1) Uses in connection with residential dwelling;
(2) Private swimming pool and tennis court associated with dwelling units; and
(3) Private garage, carport, storage shed and parking area associated with above uses and/or dwelling units.
(D) Other uses not expressly permitted by right are prohibited.
(E) Lot and building provisions.
