"Accessory Dwelling Units Rock. But Should States Be Overriding Cities' Laws About Building Them?" (Podcast)

Building an accessory apartment is one of the gentlest ways you can increase the housing stock in your town. But does that mean that states should be the ones making the rules about how you can do it—even if those rules are permissive?

"So You Want to Build an ADU?"

Let’s walk through what it actually takes to build a small rental apartment on your property in Austin, Texas. It’s a lesson in how the city’s existing code stymies gentle, incremental, small-scale development.

"Three Cheers for Lexington's ADU Ordinance"

Lexington, Kentucky, recently proposed an ordinance that would allow accessory dwelling units. Nolan Gray explains how ADUs are good for renters, good for homeowners, and good for the city — and why Lexington’s ordinance is (almost) perfect.

"California ADU Reform: A Retrospective"

Gray explores how laws related to ADUs have been changing in recent years. Since streamlining the permitting process in 2016, California policymakers have laid out a statewide set of rules for legalizing ADUs. Gray states that ADU legalization has led to a building boom, and that ADUs now represent a large share of new housing that's being produced in many cities across the state. This legalization success serves as a model for future land-use reforms in California and other states attempting to address the housing shortage.
