Should local governments remove mandatory parking requirements to help lower the cost of new housing?
A UCLA study found that city-imposed parking mandates significantly increase the cost of building new apartments while impacting housing density nationwide. These requirements often force households to pay for parking spaces they do not use, as 71% of carless households currently subsidize this infrastructure.
Why it matters
Mandated parking minimums increase development expenses by 38% for small apartment projects, directly affecting the final price tag for renters and owners. Understanding these policy impacts helps residents evaluate how local zoning changes influence the affordability and availability of housing in their communities.
A national study reveals that 71% of carless households pay for unused parking, while underground parking spaces now cost an average of $73,000 to construct. These mandates contribute to an estimated $35,000 in added costs per apartment unit in developments like Weyburn Terrace.
The players
UCLA
The university whose researchers analyzed the relationship between municipal zoning requirements and housing construction costs.
The details
Zoning codes historically required developers to include a set number of parking spaces for every new residential unit, a practice that fundamentally shifted the economics of construction. Because building a single underground space costs an average of $73,000, these requirements create a high financial barrier that reduces the number of total units developers can afford to build. When cities like Seattle repealed these mandates, they avoided $537 million in construction spending over five years, demonstrating how policy shifts alter the supply and cost of local housing.
Timeline
1961: Oakland implemented a mandate requiring one parking space per apartment.
Over five years: Seattle saved $537 million in construction costs after repealing similar parking mandates.
Money Landscape
Parking mandates represent a decades-old zoning strategy that has fundamentally constrained the efficiency of the U.S. housing market. The recent shift toward repealing these requirements marks a departure from historical planning norms that prioritized vehicle capacity over residential density.
Renters in cities with strict parking mandates are likely paying a premium in their monthly lease to cover the construction and maintenance of unused parking. If you are shopping for a new apartment, consider asking a professional about local parking regulations and how they impact the total unit price versus building amenities.
The takeaway
The cost of building mandatory parking is often passed directly to residents, even those who do not own a vehicle. Consider reviewing your lease agreement or local municipal zoning board meeting minutes to understand how parking requirements may be influencing your housing expenses.
