The programs most typically are designed to take as affordable housing some portion of the units being built as market housing. As a result, the affordable units typically are the same as the market units in size (number of bedrooms and square footage) and tenure. This housing is then provided at a price or rent substantially below market price for the equivalent market units.
So, if the market-rate units are provided as ownership units, then the affordable units typically will be as well. And, if the market-rate units are small (or large) units, then the affordable units will be as well in more or less the same mix of sizes and types.
