You mean zoning codes and not building codes? Zoning codes have indeed primarily caused the lack of small buildings. Also a lack of understanding of property values and induced traffic. If I have a 40ft wide lot in a city and I want to build on it (I may not even be able to because of 'minimum width' requirements on lots), but if I do, I might only be able to build a tiny house on it in the very middle of the lot because of 10ft setbacks on either side. What do people do in this case? The lot gets purchased along with the one next to it by some rich people and then they build a massive house on it. The total value of the house may actually be less as a single house than two houses, but the zoning codes have forced it to a less valuable land use that is more spread out.
