Here’s a complete set of readings for you, ranked in priority order.
1. “AB 710 Will Reduce the Cost and Increase the Supply of Affordable Housing.”
a. This is the brief I co-wrote with Don Shoup and Mike Manville from UCLA.
b. Summary: Parking reductions tied to affordability covenants have had only induced market-rate developers to produce a trivial number of affordable housing units. Still, current parking codes constrain even developers of affordable housing. AB 710 will not significantly alter the existing incentives for market-rate developers to provide affordable housing. Moreover, it will significantly enhance the existing incentives and likely boost production among both affordable and market-rate developers.
2. SB 1818 Parking Incentives—Multiple Cities
a. A summary I produced comparing the SB 1818 parking reduction and existing parking codes in California’s seven largest cities—the locales where AB 710 will have the greatest impact.
b. Summary: SB 1818 offers no parking benefits for any units larger than a two bedroom, further evidence that AB 710 will not undermine important incentives.
3. “The High Cost of Free Parking,” Chapter 5
a. An excerpt from Don Shoup’s revolutionary treatise on how our approach to parking regulation has destroyed cities, damaged housing affordability and brought any number of additional evils.
b. Summary: On pages 141 to 153, in particular, Shoup presents studies showing how the costs of providing parking are inevitably passed on to the renters, buyers and other end-users of real estate. He also cites a study showing how housing with less parking commands lower market prices.
4. The Victoria Transportation Institute’s “Parking Requirement Impacts on Housing Affordability”
a. A broad overview of how parking costs flow through to housing prices
5. SCANPH’s “Parking Requirements Guide for Affordable Housing Developers”
A 2004 document that makes excellent points about parking requirements. Specifically:
a. Parking requirements increase development costs
b. They reduce the space available for other amenities and services
c. They produce less attractive designs
My favorite quote: “Is All This Parking Needed? No. Parking requirements have largely been arbitrarily determined and do not usually reflect the verifiable parking needs of the people who will make use of a development.”
6. Excerpt from the Dukakis Center’s “Maintaining Diversity In America’s Transit-Rich Neighborhoods: Tools for Equitable Neighborhood Change”
a. This report is often cited by those opposing AB 710. Interestingly, the only mention of parking requirements is on the two pages I’ve attached, in which the report says quite clearly, reducing them makes housing more affordable.
