Is Parking Cash-Out Worth It? Comparing Cost-Effectiveness And Climate And Equity Benefits In The Bay Area And South Coast Air Quality Management Districts, Fynnwin Prager, Tianjun Lu, Ashley Membere, Parveen Chhetri

Mineta Transportation Institute

This research explores the potential impacts of California parking cash-out policy changes on the Bay Area and LA County. Parking cash-out—a California law since 1992—requires that certain qualifying employers who subsidize employee parking offer employees the option to give up their parking space and receive cash instead. Studies show parking cash-out substantially reduces VMT and emissions, yet enforcement remains voluntary. Current policy covers few firms (<1%) and employees (around 11%) in the study regions. Policy reform to include companies with 20+ employees could increase this to 18%. Our experimental-design survey (n=963) explores behavioral changes in response to multiple policy variables and finds that 76.9% of employees would accept cash-out if offered, and that participants who had to pay the market rate for parking and were full-time commuters were more likely to switch to using public transportation at lower cash minimums. VMT related to employees covered by parking cash-out are substantial (5.6 million in the Bay Area; 5.7 million in LA County), and account for a combined 6,593 daily tons of GHG. As even limited adoption could have significant environmental benefits, parking cash-out would be a more cost-effective approach to reducing VMT than traditional TDM programs such as trip-reduction programs, workplace parking taxation, or transit subsidies and road diets, though further evidence on the direct influence of parking cash-out on commuter behavior is needed.
