Oct 16, 2024 Shane Phillips, a housing policy expert from UCLA, is joined by Mike Lenz, a former public policy professor at USC. They dive deep into the complexities of inclusionary zoning (IZ) in Los Angeles, challenging conventional beliefs about who bears its costs. Rather than developers, they argue all renters share the burden. Insights from a development simulator reveal potential impacts on housing production. The duo also reflects on the nuances of research data and the need for localized policy changes to truly address the affordable housing crisis.

Episode notes
Inspiration for Research
- Shane Phillips's research was inspired by Emily Hamilton's findings on inclusionary zoning's impact on housing prices.
- Hamilton observed faster price growth in areas with inclusionary zoning, despite no significant change in production.
Isolating IZ's Impact
- Inclusionary zoning policies often pair with upzoning, making it difficult to isolate IZ's impact.
- Shane Phillips focused on changing IZ requirements while holding other factors constant to simulate various scenarios.
Simulator Mechanics
- The Turner Housing Policy Simulator calculates the most profitable use for each parcel, considering zoning and market conditions.
- Applying development probabilities to each parcel allows for estimating citywide production over time.
