A Parking Paradox

Minimum parking requirements affect developer behavior most where they are most controversial: in downtown neighborhoods. In suburbs where they may just mimic the market, the arguments for such rules are paradoxically even weaker.

One common argument against the abolition of minimum parking requirements is that abolition would be futile: developers generally build as much parking as the law requires and then some. 

A recent article in Access magazine by Cornell planning professor Michael Manville suggests otherwise. Manville studies the impact of Los Angeles’ "Adaptive Reuse Ordinance" (ARO), which provides that landowners who convert downtown commercial/industrial land to residential use need not build additional parking, even if city ordinances would otherwise require such parking. 

Manville finds that the overwhelming majority of ARO landowners provided some parking: only 13 percent of ARO apartments, and 31 percent of condominium buildings, were completely parking-free. However, this statistic underestimates landowners’ use of the flexibility provided by the ordinance, since some of the buildings may have had preexisting parking.

In addition, ARO buildings typically provided less parking (or at least less on-site parking) than Los Angeles law requires for other buildings.For condos, Los Angeles typically requires two parking spaces per unit; however, the minimum ARO unit provided 1.3 spaces. ARO apartment units typically complied with the city’s one-space-per unit requirement; however, ARO apartment parking spaces, unlike most Los Angeles parking spaces, are often off-site. The typical ARO unit had only 0.6 parking spaces; thus, many landowners leased parking from nearby parking spaces, providing the developers with additional flexibility and reducing housing costs.

Manville points out that his findings are limited to downtowns, where parking may be more expensive and people are more willing to live car-free. By contrast, in low-density suburban areas where parking is cheap and driving is universal, developers may be more willing to build huge amounts of parking. Yet the latter areas are, it seems to me, the least willing to experiment with parking reform.

These conclusion, if true, suggests a paradox: minimum parking requirements are most popular precisely where they have the least impact. If suburban landowners will build more parking than the law requires, isn’t the law kind of pointless? 

The traditional argument for minimum parking requirements is that they prevent people wasting fuel and time cruising for scarce parking spaces. But if suburban landowners will always build parking, there is no scarcity and hence no cruising.

A second argument for minimum parking requirements is that they prevent "spillover parking": that is, people parking in residential areas, inconveniencing residents who crave on-street parking spots. But this argument does not apply to many suburban areas because if parking is nearly always abundant, such spillover parking will never occur. Moreover, suburbanites are less likely to use parking than city drivers, because they usually park in their own driveways and garages. 

So in car-oriented suburbs, minimum parking requirements may not do much harm- but they don’t do much good either.
