Updated 1/11/24 to add 3 new papers, Wegmann, Baqai, and Conrad (2023), Dobbels & Tavakalov (2023), and Hamilton (2024). The original post was published 3/14/23. A concerted research effort has brought minimum lot sizes into focus as a key element in city zoning reform. Boise is looking at significant reforms. Auburn, Maine, and Helena, Montana, did away with minimums in some zones. And even state legislatures are putting a toe in the water: Bills enabling smaller lots have been introduced [in 2023] in Arizona, Massachusetts, Montana, New York, Texas, Vermont, and Washington. The bipartisan appeal of minimum lot size reform is reflected in Washington HB 1245, a lot-split bill carried by Rep. Andy Barkis (R-Chehalis). It passed the Democratic-dominated House of Representatives by a vote of 94-2 and has moved on to the Senate. City officials and legislators are, reasonably, going to have questions about the likely effects of minimum lot size reductions. Fortunately, one major American city has offered a laboratory for the political, economic, and planning questions that have to be answered to unlock the promise of minimum lot size reforms.

Emily Hamilton (2024) addresses the same question by comparing land price growth in areas where minimum lot sizes were lowered in 2013 to areas where it had been lowered in 1999.
Nobody has critiqued or dissected Shortell (2022) yet. It is an excellent master’s thesis, but readers should bear in mind that it is student work and has not undergone peer review. Given the disagreement between these two papers – which both rely on assessment data – more research may be needed.
