Parking minimum requirements — zoning code provisions that mandate a minimum number of parking spaces for new development based on land use type — have shaped urban development patterns in North American cities for over 70 years. The academic and policy critique of parking minimums has grown substantially since Donald Shoup’s influential “The High Cost of Free Parking” (2005), and several cities have acted: eliminating or significantly reducing parking minimums in urban cores, transit corridors, and increasingly city-wide. Understanding the policy rationale, the evidence from cities that have reformed, and the implications for parking operators and investors is increasingly important as the reform trend expands.
The Case Against Parking Minimums
Distortion of development economics: Parking minimums require developers to provide a defined parking count regardless of actual demand. In urban markets with adequate transit and walkability, required parking often exceeds actual demand — resulting in excess supply that sits underutilized and inflates development cost.
Cost burden passed to consumers: Structured parking costs $20,000 to $50,000 per space to build; surface parking forecloses higher-value land uses. These costs are typically passed to tenants and buyers in the form of higher rents and purchase prices, effectively subsidizing parking for car-owning residents and workers at the expense of all residents.
Land consumption and urban form: Parking minimums have historically required that a significant fraction of urban land serve as parking — suppressing density, creating unwalkable street environments, and increasing the distances between destinations that make driving necessary.
Induced vehicle ownership and VMT: Making free or low-cost parking abundant in housing and employment centers increases vehicle ownership rates and vehicle miles traveled among residents who would use transit or active transportation if parking were less abundant or more costly.
Cities That Have Eliminated or Reduced Parking Minimums
The parking minimum reform movement has accelerated in the 2020s:
Minneapolis: Eliminated citywide parking minimums in 2021 as part of its 2040 Comprehensive Plan implementation. The first major U.S. city to do so without limiting the elimination to specific zones or districts.
San Jose, California: Eliminated parking minimums citywide in 2022, making it one of the largest U.S. cities to do so.
Austin, Texas: Eliminated parking minimums citywide in 2023, with a process that was remarkably broad-based in its political support.
Buffalo, New York: Eliminated parking minimums as part of its 2017 Green Code overhaul, one of the earlier citywide eliminations.
Hartford, Connecticut; Raleigh, North Carolina; Lexington, Kentucky: Among other mid-size cities that have eliminated or substantially reduced parking minimums.
California statewide: California AB 2097 (2022) prohibits cities from imposing parking minimums on residential or commercial development within one-half mile of public transit with adequate service — effectively eliminating parking minimums for transit-adjacent development statewide.
The reform has extended beyond the most transit-rich cities; its expansion to Austin, San Jose, and Raleigh (cities with significant car culture) suggests that the policy arguments have achieved broad political viability.
Impacts on Development Economics
Eliminating parking minimums does not eliminate parking demand — it allows the market to determine the optimal parking supply for each development:
Reduction in parking provided: Developments built without parking minimums often provide less parking than the minimum would have required, but not zero — developers provide the parking that the market supports at the projected price point and tenant mix.
Lower development cost: Reducing structured parking increases the financial feasibility of infill development. Several housing studies have found that eliminating parking minimums near transit enables housing construction that would not pencil with the required parking cost burden.
Shift toward paid parking: When parking is no longer bundled with residential or commercial tenancy as a required minimum, developers are more likely to charge separately for parking access — which reduces unnecessary vehicle ownership and creates a parking revenue stream.
Increased development activity: Several cities that have eliminated parking minimums have observed increased development applications in affected areas, particularly for smaller infill projects where parking minimums were the primary feasibility barrier.
Implications for Parking Operators and Investors
Increased demand for third-party parking: As new development provides less bundled parking, residents, employees, and visitors in those developments who do own vehicles have demand for third-party parking. Established parking facilities near minimums-reform areas may see demand from vehicle owners in nearby parking-minimal buildings.
Parking supply rationalization: In markets where excess supply previously existed because minimums required more parking than demand justified, reform allows supply to align more closely with actual demand — potentially improving utilization and revenue per space for remaining facilities.
Reduced future supply competition: New development in minimums-reformed areas provides less parking than previously. This is favorable for existing parking facilities in those areas, as less competing supply enters the market.
Parking unbundling as a revenue model: Multifamily developments that previously included parking in rent (to satisfy minimum requirements) are shifting to unbundled parking pricing. This creates opportunities for third-party parking operators to offer residential parking programs to residents of adjacent unbundled developments.
Investment risk in markets with reform: Parking facility investors in markets with active minimum reform should assess whether the reform reduces the pipeline of parking-minimal new development (which would reduce demand for third-party parking in those areas) or reflects a market with sustained parking demand that the minimum was merely suppressing.
Frequently Asked Questions
Does eliminating parking minimums reduce parking supply? Not necessarily. It removes the floor on required supply, allowing developers to provide what the market supports. In transit-strong markets, parking provided in minimums-reformed areas often falls below what minimums would have required. In car-dependent markets with limited transit, developers continue providing parking at or near previous minimum levels because the market demands it.
What is Donald Shoup’s argument against parking minimums? Shoup argues in “The High Cost of Free Parking” that parking minimums mandate a parking supply that exceeds demand, creating excess supply that is typically priced at or near zero, which subsidizes driving, increases vehicle ownership, and distorts land use toward auto-dependency. He advocates for eliminating parking minimums and pricing on-street parking at market rates to manage demand efficiently.
How do parking minimums affect housing affordability? Structured parking adds $20,000 to $50,000 per space to development cost, and underground parking can add $40,000 to $90,000 per space in high-cost markets. When parking minimums require each housing unit to include 1 to 2 parking spaces, the cost burden is significant — particularly for affordable housing developments where the cost cannot be offset by higher rents.
Will parking minimum reform reduce parking revenue for commercial parking operators? The relationship is complex and market-dependent. In markets with genuine parking demand suppression (more demand than the current supply serves efficiently), reform may allow supply reduction that improves utilization and revenue per space. In markets where excess supply already exists, reform that reduces future supply competition may improve existing operator economics. Each market requires independent analysis.
Takeaway
Parking minimum reform has moved from an academic policy proposal to an implemented reality in an expanding number of North American cities. The policy case against parking minimums — excess supply, development cost burden, induced driving — has achieved broad political traction that would have been difficult to predict a decade ago. For parking operators and investors, the reform trend is a market environment shift that requires understanding: reduced new supply from minimums-reformed development, potential demand from parking-minimal buildings, and changed investment assumptions for parking facilities in reform markets. The operators who understand their specific market’s reform status and demand dynamics will make better-informed investment and operational decisions than those treating parking minimum policy as purely a planning department concern.
