“Find ways to give vocal minorities opt-out mechanisms where they can have some of the land use rules that they want, but they don’t get to drag the whole city down with them.” That’s one of Nolan Gray’s primary lessons from the success of minimum lot size reform in Houston, and a prescription for land use reform more generally. Houston’s reform, which took place in 1998, reduced the minimum parcel size for new homes from 5,000 to just 1,400 square feet per unit, and it’s produced tens of thousands of low-cost townhome-style houses in the city’s “inner loop.” It also allowed individual neighborhoods to opt-out of the reform, creating a political context in which reform could move forward. Gray, a doctoral student at UCLA and author of the new book, Arbitrary Lines: How Zoning Broke the American City and How to Fix It, joins us to talk about the lessons we can learn from the famously unzoned city of Houston, and the promise that minimum lot size reform holds for improving affordability and giving residents more choice in how they live their lives.
