>Shouldn't they be mostly Studio and 1-bedroom apartments No. It's not an intuitive result, but it makes sense when you think about it. Bedrooms are cheap to build. Kitchens and bathrooms are expensive to build. Building 3 units with a total of 3 bedroom, 3 kitchens, and 3 bathrooms is a much less efficient setup than building a 3 bedroom 2 bathroom unit. If you incentivize people to have roomates or co-habitate with extended family by building bigger suites you can make housing cheaper overall.
