Why Single-Stair Buildings Are Shaking Up U.S. Housing: A $1,500 Lesson from Seattle
Single-stair apartment buildings are challenging traditional construction norms in the U.S., driven by housing shortages and high costs. But can this concept balance safety and affordability?
Why are single-stair apartment buildings causing such a stir in the U.S. housing market? As urban areas face intense housing shortages, this unassuming design choice is at the forefront of a growing debate over cost, safety, and density.
The Numbers Don't Lie
The raw data shows that building requirements for double staircases increase costs by 6% to 13%, taking up about 7% of floor space. This is a significant factor in a market where every square foot counts. In Seattle, single-stair apartments can offer rents starting at approximately $1,500/month for a studio, providing a glimpse into potential affordability in other cities if such reforms spread.
Over 30 locations across North America are now considering relaxing these restrictions, with rapid changes expected in local building codes.
Why It Matters
Historically, the U.S. has been a stickler for multiple stairways in residential buildings, unlike many parts of the world. The reason? Fire safety. Yet, this tradition hasn't kept up with the adoption of modern fire protection systems like sprinklers, which have reduced fire deaths by 90% between 2017 and 2021.
Seattle's bold move in the 1970s to allow single-stair buildings was a response to a housing crisis. Now, as cities like LA and Denver grapple with similar issues, the question is whether they're willing to make the same leap.
Experts Weigh In
According to Stephen Smith, executive director of the Center for Building in North America, the extra cost of a second stairway could halt much-needed housing projects. "It's not just about safety," he argues. "It's about making housing feasible in urban centers where every inch of space is at a premium."
Fire officials, however, remain skeptical. Karen A. Grove of the Seattle Fire Department highlights the additional burden on the department, as they become the fallback plan when a single exit is blocked. Meanwhile, advocates like Travis Morgan from the Livable Communities Initiative see these reforms as essential to creating livable, walkable communities.
What's Next?
Is this trend sweep the nation? With cities like Culver City and Denver already adopting Seattle-inspired ordinances, it's a movement that's gaining traction. But the path forward isn't without obstacles. Fire departments across the U.S. are apprehensive, citing safety concerns that might slow down these reforms.
For now, it's a balancing act. Cities must weigh the benefits of increased housing density and affordability against potential safety risks. The success of single-stair reforms could very well set a precedent for the rest of the U.S. housing market. Will we see a single-stair revolution, or will fear of the unknown hold us back?
This ends badly if the math doesn't add up. But if cities can adapt, we might witness a quiet revolution in how urban spaces are designed and lived in.
