Inclusionary zoning. It was introduced in my hometown in the 1980s and it worked. Whatever you are uulding, a percentage need to be allocated for rent geared to income or multi-family for sale that is below single-family market values. It was particularly effective in market rentals. We also need to become more creative in multi-family. Take a look at Park 17 in Denver -- really crrative modular housing. Argyle Gardens in Portland Oregon is another reative modular design.

We need to do other things. We need to improve the efficiency of the permitting system. We need to study the viability of tax exemptions for missing middle housing. We need to find more cost-effective energy efficiencies.
