Design. The following design requirements apply to affordable housing developments, excluding prior round units.

Design of 100 percent affordable developments:

Restricted units must meet the minimum square footage required for the number of inhabitants for which the unit is marketed and the minimum square footage required for each bedroom, as set forth in the Neighborhood Preservation Balanced Housing rules at N.J.A.C. 5:43-2.4.

Each bedroom in each restricted unit must have at least one window.

Restricted units must include adequate air conditioning and heating.

Design of developments comprising market-rate rental units and restricted rental units. The following does not apply to prior round units, unless stated otherwise.

Restricted units must use the same building materials and architectural design elements (for example, plumbing, insulation, or siding) as market-rate units of the same unit type (for example, flat or townhome) within the same development, except that restricted units and market-rate units may use different interior finishes. This shall apply to prior round units.

Restricted units and market-rate units within the same affordable development must be sited such that restricted units are not concentrated in less desirable locations.

Restricted units may not be physically clustered so as to segregate restricted and market-rate units within the same development or within the same building, but must be interspersed throughout the development, except that age-restricted and supportive housing units may be physically clustered if the clustering facilitates the provision of on-site medical services or on-site social services. Prior round affordable units shall be integrated with market rate units to the extent feasible.

Residents of restricted units must be offered the same access to communal amenities as residents of market-rate units within the same affordable development. Examples of communal amenities include, but are not limited to, community pools, fitness and recreation centers, playgrounds, common rooms and outdoor spaces, and building entrances and exits. This shall apply to prior round units.

Restricted units must include adequate air conditioning and heating and must use the same type of cooling and heating sources as market-rate units of the same unit type. This shall apply to prior round units.

Each bedroom in each restricted unit must have at least one window.

Restricted units must be of the same unit type as market-rate units within the same building.

Restricted units and bedrooms must be no less than 90 percent of the minimum size prescribed by the Neighborhood Preservation Balanced Housing rules at N.J.A.C. 5:43-2.4.
