Zoning Reform: A Key Step in Solving America’s Housing Affordability Crisis

The United States faces a significant housing deficit, with estimates indicating a shortage of 3-4 million units. This shortage disproportionately impacts low- and middle-income households, driving up prices and putting housing out of reach for many. At the heart of this issue are restrictive zoning rules that limit the construction of higher-density housing, particularly in urban areas where demand is highest. However, there are promising signs of change.

Zoning Reform in Action: Success Stories from Across the U.S.

Several cities are leading the charge in zoning reform, proving that smart policy changes can make a real difference:

• Minneapolis, MN: By eliminating minimum parking requirements for new developments and allowing more housing near transit and commercial areas, Minneapolis increased its housing stock by 12% from 2017 to 2022. Much of this growth came from mid-sized apartment buildings (20+ units), which helped stabilize the city’s rent prices. While rents increased by only 1% in Minneapolis during this period, they rose by 14% across the rest of Minnesota.
• Houston, TX: In Houston, policymakers reduced minimum lot sizes from 5,000 square feet to 1,400, sparking a townhouse construction boom. The increased housing stock has slowed rent growth and provided more options for renters and buyers alike.
• California: At the state level, California passed legislation in 2020-2021 to address its severe housing shortage, including laws to streamline permitting for accessory dwelling units (ADUs). By 2022, over 28,000 ADU permits had been issued, highlighting the potential of small-scale, infill development to expand housing options quickly.

Challenges Ahead: The Need for Broader Zoning Reform

Despite these successes, much of the U.S. remains heavily restricted by zoning rules that limit housing diversity. In many cities, over 75% of residential land is zoned exclusively for single-family homes. This creates an environment where alternative housing options, like row houses and apartments, are often prohibited, exacerbating the shortage and driving up prices.

According to Pew Charitable Trust, the dynamics seen in Minneapolis pre-2017 are mirrored nationwide. Housing shortages have driven up rents and home prices in nearly every state, with underproduction worsening in 75% of U.S. metropolitan areas.

Building Beyond Zoning Reform: Addressing the Supply Chain and Labor Shortages

While zoning reform is essential, it’s only part of the solution. Expanding housing stock also requires addressing labor shortages in construction, an issue that may be even harder to solve long-term. Without enough skilled workers, increasing the housing supply will remain a challenge.

A Vision for the Future of Housing

To solve the affordable housing crisis, innovation is needed on multiple fronts. As American architect David Wallance suggests, the goal is to “harness global forces to build equitable housing and cities” and make quality, affordable housing available as a well-designed, accessible product. At Hive Modular, we’re committed to advancing this mission by rethinking traditional construction and using modular approaches to deliver high-quality, efficient housing.

The journey is challenging, but zoning reform, combined with innovative construction approaches, is key to realizing a future where housing is both affordable and available for all.
