In which types of homes are people safest from fires? Alex Horowitz shares research showing that multifamily is safer than single-family housing, newer homes are much safer than older homes, and that a single stairwell’s just as good as two.

Your city just legalized “missing middle” housing in its zoning code… now what? With Memphis, Tennessee, as a case study, John Zeanah and Andre D. Jones discuss the hidden non-zoning barriers to developing small apartment buildings — and how to lower them. This is part 4 of our series on misaligned incentives in housing policy.

'Beyond Zoning' Abstract:

In recent years, planners have made zoning reform a key priority to enable housing supply, including “missing middle” housing … This article explores the barriers beyond zoning that can hold back development of middle-scale housing. It begins with a background on why these lesser-known codes matter for housing diversity. This is followed by a case study of a project in Memphis, highlighting the non-zoning barriers posed to the development of an infill collection of cottages and small apartment buildings, and how they were overcome. Next, the article delves into specific categories of barriers, from building codes and fire safety mandates to infrastructure and local ordinances, explaining how each can impede middle-scale housing projects. Finally, it concludes with an Action Steps for Planners section, offering implementable strategies for reforming codes and coordinating across departments to unlock middle-scale housing development.

The hosts gather to celebrate the 100th episode of UCLA Housing Voice. We also answer listener questions and announce the first book for our book club.

North American buildings are built different — literally. Councilmember Jesse Zwick explains how the organization behind our unusual standards is built to fail, and he makes the case for a new approach. This is part 3 of our series on misaligned incentives in housing policy.

Elevators in the U.S. and Canada cost 3–5 times as much as elevators in other high-income countries. Stephen Smith explains why and how our well-intentioned elevator standards make cities less safe and accessible. This is part two of our series on misaligned incentives in housing policy.

Abstract:

Americans make over 20 billion trips per year by elevator – twice the number of trips made by what people think of as mass transit. Despite the association between elevators and high-rises, the average elevator in the United States only has four landings, with elevators being as much a tool for convenience and accessibility as for able-bodied necessity.

But despite being the birthplace of the modern passenger elevator, the United States has fallen far behind its peers. Elevators in the United States have remained a fairly niche item in residential settings – expected in a high-rise or a big new mid-rise apartment building, but otherwise largely absent from the middle-class home. In absolute terms, the United States has fewer elevators than Spain – a country with one-seventh the population, and fewer than half the number of apartments. 

And behind its lack of elevators, North America faces a crippling cost problem. The price to install an elevator in a new mid-rise building in the United States or Canada is now at least three times the cost in Western Europe or East Asia. Ongoing expenses like service contracts, periodic inspections, repairs, and modernizations are just as overpriced. High-income countries with strong labor movements and high safety standards from South Korea to Switzerland have found ways to install wheelchair-accessible elevators in mid-rise apartment buildings for around $50,000 each, even after adjusting for America’s typically higher general price levels. In the United States and Canada, on the other hand, these installations start at around $150,000 in even low-cost areas.

This is the first episode of our series on misaligned incentives in housing policy. Michael Eliason shares insights from his book, Building for People, on building code reforms and eco-district redevelopment projects throughout Europe.

Housing vouchers provide critical assistance to low-income renters, but roughly 40% of vouchers go unused, in part due to difficulty finding landlords to accept them. Vincent Reina shares findings from a pilot program that instead gives cash assistance directly to tenants.

Abstract: 

This article examines a new rental assistance program in Philadelphia, called PHLHousing+, that disburses unconditional cash payments directly to tenants to eliminate their housing cost burden. The program is designed as a 2.5-year randomized controlled trial that aims to test the impact of direct- to-tenant cash assistance on household outcomes compared with traditional housing vouchers. The motivations for the program range from the need for more flexible tools that respond to the diverse needs of low-income renters to the desire for a robust evidence base on effective policies to improve household outcomes. The article also discusses the evolution of the idea behind PHLHousing+ before the COVID-19 pandemic through to its development, using knowledge obtained from upscaling local pandemic emergency rental assistance programs. Finally, the article describes the program’s implementation, including participant enrollment, strategies to minimize benefits loss, and cash disbursement mechanisms. It reflects on the lessons learned throughout this process, such as the importance of flexible funding and a strong research-practice partnership. The goal is to provide guidance to those planning similar programs and inform local and national policy, especially on direct-to-tenant, cash-based housing assistance.
