How "Perfect" Building Codes Harm Housing Affordability and Accessibility

This conversation reveals a profound, hidden consequence of seemingly minor regulatory decisions: the systematic erosion of housing affordability and accessibility in the United States. By dissecting the history and economics of elevator adoption, the discussion highlights how a pursuit of perfection in building codes, driven by edge cases, inadvertently creates significant downstream costs. These costs manifest as fewer elevators, making multi-story buildings inaccessible to the elderly and disabled, and ultimately increasing the price of housing for everyone. This analysis is crucial for urban planners, policymakers, developers, and anyone concerned with the future of urban living, offering them a framework to understand how well-intentioned regulations can lead to unintended, detrimental outcomes, thereby providing a strategic advantage in advocating for more pragmatic and equitable building standards.

The Unseen Cost of "Perfect" Elevators

The narrative surrounding the scarcity of elevators in American buildings, particularly in new, multi-story apartment complexes, is not merely a matter of inconvenience; it's a systemic issue with deep roots in regulatory processes and a flawed pursuit of perfection. Stephen Smith, Executive Director of the Center for Building in North America, meticulously unpacks how a single amendment to a building code, proposed by a fire inspector in Glendale, Arizona, Greg Victor, inadvertently inflated the cost and complexity of elevators to a point where their inclusion in many new buildings became economically unviable. This cascade of consequences, from individual accessibility to the broader housing market, demonstrates a classic case of systems thinking gone awry, where a localized, well-intentioned solution creates widespread, negative downstream effects.

Initially, the problem appears straightforward: why are there so few elevators in the U.S. compared to countries like Greece, which has roughly half the elevators per capita despite a significantly smaller population? Smith’s investigation reveals that this isn't due to a lack of technological capability; the modern elevator is an American invention. Instead, the issue lies in the economics and regulatory landscape. In Europe, new three-story buildings commonly feature elevators that cost around €20,000-€30,000. In the U.S., a comparable elevator could cost $100,000-$150,000. This stark difference, as Smith explains, is not solely attributable to labor costs, though the specialized and highly unionized American elevator workforce does contribute. A significant factor is the insistence on assembling elevators on-site in the U.S., a practice that contrasts with the European method of factory assembly and on-site installation.

"The most cost effective way to build an elevator is to assemble the whole thing in a factory then ship it to the building site and drop it in with a crane. That's what they do in Europe. But in the United States, the elevator union insists on assembling the elevators themselves."

This on-site assembly, akin to children disassembling and reassembling building blocks, adds labor and time without necessarily improving the final product's functionality. However, even this doesn't fully account for the five-fold cost difference. The true culprit, as Smith elaborates, lies in the size of American elevators. Driven by a desire to accommodate the rarest of edge cases, such as a fully extended stretcher for a cardiac arrest patient, American building codes mandated larger elevator dimensions. This pursuit of accommodating a hypothetical, extreme scenario led to elevators so bulky and expensive that they became prohibitive for smaller apartment buildings and affordable housing projects.

"The perfect is the enemy of the good. This is American elevator policy. This too many people are dying in car accidents. Let's mandate that everyone has to drive to the store in a tank. Problem solved?"

This illustrates a critical failure in consequence mapping: optimizing for an infrequent, high-stakes event (a cardiac arrest requiring a stretcher) at the expense of a common, everyday need (accessible housing for a broader population). The consequence is a system that effectively segregates individuals who cannot easily navigate stairs, including the elderly and those with disabilities, from desirable living spaces. Smith himself experienced this firsthand when a chronic illness rendered him effectively disabled, making the third floor of his own building a significant barrier. This highlights how the "perfect" solution--an elevator large enough for any conceivable emergency--renders the elevator, and thus many buildings, entirely useless for a substantial portion of the population.

The amendment proposed by Greg Victor, which sought to mandate elevator accommodation for "whatever structure the jurisdiction has got," and later refined to a specific length, bypassed a rigorous cost-benefit analysis. The proposal was presented to a broader membership of building officials, where emotional appeals about potential medical emergencies carried more weight than the economic realities. The cost impact question on the amendment form was answered with "NONE," a deliberate omission that allowed the true economic consequences to be masked. This is where conventional wisdom fails when extended forward: assuming that making a system "perfect" for extreme cases will universally improve it. Instead, it creates a system that is unaffordable and inaccessible for the majority.

The Hidden Price of Perfection

The ripple effects of this single regulatory change are far-reaching. By making elevators prohibitively expensive, the code effectively dictates that many new multi-story buildings will rely solely on stairs. This creates a tiered system of housing: those who can afford elevators in larger, more expensive buildings, and those relegated to walk-ups, often in less desirable locations or with fewer amenities. The "YIMBY" (Yes In My Backyard) movement, with which Smith is aligned, fundamentally opposes regulations that stifle housing development and affordability. From this perspective, the elevator code is a prime example of how well-intentioned safety measures, when taken to an extreme, can actively work against the goal of creating more housing and more equitable access to it.

The core of the problem lies in how building codes are amended and enforced. The International Building Code (IBC), while aiming for standardization, is a living document subject to proposals from individuals and organizations. This process, intended to be responsive, can be exploited by those with specific agendas or a narrow focus, as demonstrated by Victor's amendment. Without robust mechanisms to assess the broader economic and social impacts of proposed changes, such amendments can pass, creating a domino effect that impacts housing supply, affordability, and accessibility across the nation.

The story underscores a critical insight: the pursuit of perfection in regulatory standards, without a thorough understanding of the cascading economic consequences, can lead to significant societal costs. This is where delayed payoffs create a competitive advantage for those who can anticipate and navigate these systemic inefficiencies. Developers who can find ways to build more affordably, perhaps by lobbying for more pragmatic code interpretations or by focusing on building types less affected by these costly mandates, will outcompete those who are constrained by outdated or overly burdensome regulations.

The consequence of making elevators so large and expensive is not just that fewer buildings have them, but that the very concept of multi-story living becomes less accessible. This creates a hidden barrier to entry for a significant portion of the population, effectively creating a "moat" of inaccessibility around buildings that could have been more inclusive. The YIMBY perspective argues that this is a direct consequence of prioritizing an idealized, albeit rare, scenario over the practical needs of a diverse population.

• Immediate Action: Advocate for transparency and rigorous cost-benefit analysis in the building code amendment process.
• Longer-Term Investment: Support organizations and initiatives that promote pragmatic, evidence-based building codes, focusing on broad accessibility rather than extreme edge cases.
• Immediate Action: Re-evaluate elevator size requirements in building codes to balance emergency preparedness with everyday accessibility and affordability.
• Longer-Term Investment: Promote modular and factory-built elevator systems to reduce on-site labor costs and complexity.
• Immediate Action: Educate developers and policymakers about the economic impact of oversized elevator requirements on housing affordability.
• Immediate Action: Challenge the assumption that "bigger is always better" when it comes to safety features, especially when it leads to exclusion.
• This pays off in 12-18 months: Develop and promote alternative accessibility solutions for buildings that may not economically support full-sized elevators.
