Japanese style zoning, allowing density to grow as population grows, allowing mixed residential and commercial appropriate to the density, with designated industrial areas, set forth in a way that neighbors are not allowed to micromanage others in an effort to protect property values. They set these formula at a national level. Codes still exist for safety concerns. I also think that land value taxes are interesting. A five acre undeveloped downtown lot would be taxed based on the surrounding density and market potential, not based on its current development. This would encourage development where it was needed. I see our current system as broken in a number of ways, especially in regards to suburban sprawl and the regulations enshrining that - minimum square footage, parking and garage spots, etc. And many suburbs are at a low enough density that they won't be able to afford to maintain their infrastructure over time without funds from more densely populated (metro or state) areas.
