(a) 
It is not the intent of this zone to prescribe the form of ownership for the dwelling units in the MX zone. However, for purposes of regulating the location of buildings within the MX zone it is necessary to prescribe lot sizes, dimensions and setbacks. In developments where the dwelling units are not to be located on individually owned separate fee simple title lots each dwelling unit or structure shall be located so that it would comply with the prescribed lot standards if imaginary lot lines were superimposed on the development.
(b) 
In the MX zone, there shall be a mix of at least three dwelling unit types consisting of single-family, two-family, attached dwellings and multiple dwellings or a combination of these housing types within the same building. Reasonable efforts shall be made to insure that the proposed development is compatible with adjacent land uses.
(c) 
Any residential development in the MX zone must provide at least two means of vehicular access to the proposed development.
(d) 
At least 25% of the site shall be devoted to common open space. The following, or the land under the following, shall not be considered common open space: streets, driveways and parking areas, and the lot areas of privately owned individual subdivided lots. All other areas, including all undeveloped land, plazas, outdoor recreational areas and other open areas available for the use of the residents of the development shall be considered common open space. In developments where dwelling units are not located on individually owned lots the common area between units may be counted toward meeting the common open space requirements.
(e) 
Reasonable efforts shall be made to preserve and protect natural wooded areas as part of any development's open space.
(f) 
If uses other than a one-family or two-family dwelling abut the R-4 or R-1 zones a forty-foot landscaped buffer must be provided.

Pedestrian and bicycle circulation systems should be designed in a manner to reduce actual boundaries between the properties in the zone as well as to the adjacent residential uses.
(h) 
All areas not occupied by buildings, plazas or parking areas shall be suitably landscaped. Shade trees shall be provided along walks, driveways and parking areas.
(i) 
The minimum tract size shall be five acres.
(j) 
All residential units shall be handicapped accessible/adaptable to the extent required by the New Jersey Barrier Free Subcode of the Uniform Construction Code, The Council of Affordable Housing or the Federal Fair Housing Act in addition to any other governing statute/regulation. When a unit is required to be adaptable, the term "adaptable" shall mean that the dwelling unit has:
(1) 
An accessible entrance (including the landing level area extending for latch side pull side or push side clearances.)
