Missing Middle Housing Study


Expanding Housing Choice: The MMHS Phase 1 Report


The Missing Middle Housing Study will explore how new housing types could help address Arlington’s shortfall in housing supply and gaps in housing choices. 

The study, which began in the Fall of 2020, is envisioned in three phases. Anticipated outcomes include:

  • A shared understanding of the problem
  • Options for County Board consideration
  • Policy/regulation changes to enable new housing types
  • Identification of issues for further study

The study is one element under the Housing Arlington Land Use Tools Initiative.

Research Compendium

As a precursor to the study kick off, the Research Compendium consists of five bulletins that provide everyone with a common background of knowledge. They introduce housing types and terms, survey Arlington’s current housing inventory, present background information on housing affordability, review the history of land use and zoning policies, and illuminate how these elements have shaped the way Arlington exists today.
