Why We Can’t Build Apartments Like This Anymore

In most of the United States, apartment buildings taller than three stories generally need two separate exit stairs. But architects, housing advocates, and lawmakers argue that this rule has also made many small apartment buildings difficult—or financially impossible—to construct. The alternative is known as a point access block: an apartment building organized around one central stair and elevator core. Removing the second staircase can eliminate long interior corridors, make narrow infill sites easier to develop, and allow apartments to have windows on multiple sides. That can mean more daylight, better ventilation, and more practical three- and four-bedroom homes. Critics see something more dangerous: the return of single-stair tenements and buildings with no backup escape route during a fire. In this video, we examine how a staircase can shape an entire neighborhood. We compare Lincoln Park in Chicago, where older courtyard buildings and walk-up apartments became difficult to replace, with Capitol Hill in Seattle, where the building code has allowed single-stair residential buildings as tall as six stories under specific safety conditions. But this video is not really just about stairs. It is about how zoning laws, parking requirements, permitting systems, and building codes quietly determine which kinds of homes are possible. When cities make small apartment buildings illegal or uneconomical, development does not stop. It becomes concentrated into fewer, larger, and often more expensive options. A single staircase will not solve the housing crisis. But it reveals how one technical rule can reshape apartment layouts, development economics, neighborhood demographics, and the kinds of cities America is able to build. #Architecture #HousingCrisis #UrbanPlanning SPECIAL THANKS Evan Montgomery — Coproducer Daniela Osorio Sanudo — Graphics Chris Campos — Camera JB Pritzker and Team CHAPTERS 00:00 - Controversial Stair 00:43 - Point Access Block 2:19 - Lincoln Park Approach 4:09 - Capitol Hill Approach 5:53 - Safety Impact 7:37 - Legislation 8:51 - Over Regulation 9:53 - Housing Variety BIBLIOGRAPHY 1.
