The affordable units shall be integrated with the market-rate units, and the affordable units shall not be concentrated in separate building(s) or in separate area(s) or floor(s) from the market-rate units. In buildings with multiple dwelling units of similar tenure, this shall mean that the affordable units shall be generally distributed within each building with market units. The residents of the affordable units shall have full and equal access to all of the amenities, common areas, and recreation areas and facilities as the residents of the market-rate units. The affordable units shall be the same type of housing unit as the market rate units, meaning that a market rate building available to families shall not be developed to provide age-restricted housing units.
