A growing consensus argues that minimum parking requirements (MPRs) make housing more expensive. This paper examines two claims from this discussion: (1) that MPRs discourage the construction of small units; (2) that the costs of building required parking are "passed on" to buyers and renters in the form of higher prices and rents. However, the mechanisms behind these two effects have never been made explicit in the literature. This paper proposes, for each claim, a plausible mechanism relying on the specific choices of housing suppliers and consumers. We propose that MPRs discourage small units because they eliminate the most profitable floorspace/parking bundle to supply to relatively lower-income households. We propose that parking costs may be passed on by reducing the supply of housing on offer at a given price.

Where curb parking is overcrowded, drivers who are searching for a rare open curb space congest traffic, pollute the air, and produce carbon dioxide. To avoid these problems, some cities have established Parking Benefit Districts that charge market prices for curb parking and spend the revenue to pay for public services on the metered blocks. A case study of Manhattan’s Upper West Side found that charging market prices for the currently unmetered curb spaces would eliminate 22 tons of carbon dioxide emissions per block per year and yield at least $1,025 per household per year to improve public services.

We estimate the off-street parking supply of the seven most economically productive cities in Santa Clara County, California, better known as Silicon Valley. Using assessor data, municipal zoning data, and visual inspection of aerial imagery, we estimate that about 13 percent of the land area in these cities is devoted to parking, and that more than half of the average commercial parcel is parking space. This latter fact suggests that minimum parking requirements, if binding, depress Silicon Valley’s commercial and industrial densities, and thus its economic output. In an exploratory empiri...

Researchers used Seattle as a case study to find the association between TNC trips and on-street parking occupancy. They found that up to a certain point, more Uber trips meant more parking occupancy. But model predictions show that once TNC trips reach about three times what they were in 2016, parking revenues will likely decline. The final report offers policy options to help cities plan accordingly.

To alleviate many parking-related externalities, several rapidly growing cities globally are optimizing parking through “smart-parking” programs, invo…

Improving the way developers and planners assess parking demand.

Residents are often offered on-street parking at a fraction of the market price which may cause excess car ownership. However, residential parking cos…

Investigating emerging transportation services is critical to forecasting mode choice and providing appropriate infrastructure. One such infrastructure is parking, as parking demand may shift with the availability of ride-hailing services. This study uses ethnographic methods—complemented with passenger surveys collected when driving for Uber and Lyft in the Denver, Colorado, region—to gather quantitative and qualitative data on ride-hailing and analyze the impacts of ride-hailing on parking, including changes in parking demand and parking as a reason to deter driving. The study also examin...
