Missing Middle Housing Study


Phase 3

County Board Engagement

In 2020, the County began its Missing Middle Housing Study (MMHS) to explore how new housing types could address Arlington’s shortfall in housing supply. After two years of public engagement, the MMHS has reached its 3rd phase.

From September to October 2022, the Arlington County Board will host 3 Information Sessions and 11 Community Conversations regarding Missing Middle Housing. Participants will have the opportunity to learn, listen, reflect, and share their perspectives with County Board members and neighbors to inform the following steps of the MMHS process.

Click here to register if you would like to participate in one of these Information or Community Conversation sessions.

In addition to hosting community conversations and information sessions, the Board has also asked staff to develop draft zoning text and General Land Use Plan amendments for consideration by both the Planning Commission and County Board as early as late 2022. View a one-page overview of the Phase 2 Draft Framework and read the County Board's guidance to staff.

Phase 1

During Phase 1 (Oct. 2020 – Fall 2021) of the Missing Middle Housing Study, the study team relied on community engagement to identify priorities and concerns related to expanding housing supply and choice in Arlington and to determine housing types to study in Phase 2.

Community engagement took the forms of an online kick-off event, a virtual dialogue on the study’s Research Compendium, a virtual listening tour, and two online feedback opportunities.

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.
