Can American cities grow AND stay affordable?

Key Takeaways Copied to clipboard!

• The core economic paradox discussed in "Can American cities grow AND stay affordable?" is that growth, often driven by initial low costs, inevitably threatens that very affordability.  Copied to clipboard!
• Huntsville, Alabama, is proactively addressing the national housing shortfall by encouraging diverse housing production, including apartments and townhomes, and by having ample land for expansion.  Copied to clipboard!
• Increasing housing supply, even by building expensive units, can help maintain overall affordability by preventing higher-income earners from displacing residents in existing, cheaper housing stock, though low-income residents still require direct subsidy.  Copied to clipboard!

Huntsville Growth and Affordability

(00:00:14)

• Key Takeaway: Huntsville, Alabama, is experiencing significant daily population growth, attracting residents with space/defense jobs and relatively low housing costs, such as $1,250 for a three-bedroom apartment.
• Summary: Huntsville sees about 18 people move there daily, supported by aerospace jobs and cultural amenities. A resident pays $1,250 monthly for a three-bedroom apartment, which is considered a steal compared to places like Montana and Florida. Housing costs per square foot in Huntsville are approximately 25% cheaper than the national average.

Growth Threatens Low Cost

• Key Takeaway: Rapid population influx driven by low costs creates an economic paradox where growth itself threatens the initial affordability that attracted newcomers.
• Summary: Residents like Rachel are concerned that expansion inevitably leads to rising prices, illustrating the economic paradox where low cost of living drives growth, which then erodes affordability. This challenge is exemplified by cities like Austin and Atlanta, which experienced massive cost increases following periods of rapid growth.

Austin’s Rapid Cost Flip

• Key Takeaway: Austin serves as the primary example of a city rapidly transforming from an affordable, isolated area into a booming employment center, causing housing costs to more than triple over two decades.
• Summary: Austin became a booming center due to tech jobs and culture, leading to enormous growth rates over the last decade. While national home prices doubled over the last two decades, Austin’s prices more than tripled. Escaping this challenging loop requires substantially higher rates of housing production.

Huntsville’s Proactive Planning

(00:04:30)

• Key Takeaway: Huntsville city planners anticipated the national housing crisis around 2013 and focused on increasing housing supply, adding 16,000 apartment units since 2020 within the city limits.
• Summary: Huntsville’s planning manager, Dennis Madsen, recognized the impending national housing shortfall (estimated at 2.8 million units nationally) early on. Their primary strategy has been increasing housing supply, resulting in 16,000 new apartment units added since 2020 within the city. The South generally builds faster due to fewer building regulations and more available land.

Diversifying Housing Supply

• Key Takeaway: To maintain affordability, cities must diversify housing types, as building even expensive units helps by absorbing demand from higher-income residents who would otherwise push down-market prices.
• Summary: When physical expansion is limited, diversification of housing types is key, including traditional homes, apartments, and townhomes. Building higher-end units prevents affluent renters from competing for less expensive units, thereby protecting affordability for those willing to pay higher rents.

Zoning and Missing Middle

(00:07:14)

• Key Takeaway: Outdated zoning codes, historically favoring single-family homes, restrict the creation of ‘missing middle housing’ like quads, which better serve diverse modern family structures.
• Summary: Many cities struggle because zoning codes were built to support only the classic nuclear family structure prevalent in the 1950s. This excludes diverse modern households who might prefer or afford ‘missing middle housing,’ such as quads (a house divided into four units). Reestablishing codes to allow this diversity is a major focus for current planners.

Growth vs. Affordability Nuance

(00:08:41)

• Key Takeaway: Growth and high costs are not always contradictory; high costs often signal high appeal, but low-income residents require additional subsidy regardless of market growth.
• Summary: High costs in desirable places like Manhattan or San Francisco reflect the overall quality of life people seek, suggesting growth and cost are linked to appeal. However, even with growth, low-income people require additional subsidy to afford quality housing. Huntsville continues to grow, expecting over a thousand new jobs from Space Command relocation.
