Missing Middle Housing—
not too big, not too little, just right.

What’s lacking, shown in yellow, are the diverse and complementary missing middle homes, such as duplexes, triplexes, and townhomes. Source: Missing MIddle Housing.

If you’re in the market to rent or purchase a home in Michigan, you’ll likely have two primary options: a single-family home or a unit in a larger apartment or condo building close to a downtown center. You may be able to find something like a duplex or a townhome, but they’re rare because of how most cities zone residential areas. In Traverse City, for instance, about 83% of land zoned residential is reserved for single-family homes.

With housing in short supply today, many are advocating changing zoning rules to allow for more diverse housing styles.

It wasn’t always like this.
East Coast early American cities tend to have a more diverse mix of housing since more of the land was built out when missing middle housing types were the norm. This is why New York and Washington, D.C., as shown above, look so different. Looking at zoning maps, it’s common to find land that allows for greater design combinations along rail lines and historic streetcar routes. This same pattern can be found in Michigan’s older cities.
We see more multi-family housing in historic neighborhoods across Michigan. Before the 1940s, designs like duplexes and triplexes were exceedingly normal. Traverse City didn’t zone for single-family until 1943—an unusual zoning restriction at the time. If you look, you can still find beautiful multi-family homes in older parts of town. But the city adopted a zoning code in 1978 that made single-family the dominant presence it is today.

The beauty of choice

The benefits that missing middle homes bring to a city are convincing more communities to adopt policies that make them easier to build.

  • The first big benefit is that multifamily homes add greater population capacity to a city. The square footage may be the same as a single-family home, but it can house multiple families or individuals.
  • The cost to own or rent can be reduced. While a duplex or triplex will cost around the same amount to build as a single-family home of the same size, the cost can be shared by two or more families.
  • Another benefit is hidden density. Well-designed 2-,3-, or 4-unit homes can fit attractively into single-family neighborhoods from a scale and architecture standpoint, essentially blending into the feel of the block. 
  • Multifamily homes can be more energy efficient. Designs like townhomes that share walls reduce the surface area exposed to the elements, losing less heat (or cooling) and saving money and natural resources.
  • Missing middle homes can improve equity. Single-family zoning across the country perpetuates and worsens economic and racial segregation since homes in those areas tend to be priced higher. Desirable downtowns like those in the Grand Traverse region should consider affordable missing-middle housing strategies to ensure that families with more moderate incomes can live in the area.
  • Multifamily homes need less land than single-family, so they can help reduce the rate of suburban sprawl, preserving farmland and fo
