zMOD - Fairfax County Zoning Ordinance Modernization Project

Zoning Ordinance ModernizationIn 2017, Fairfax County launched a major initiative to modernize its Zoning Ordinance that was first established over 40 years ago. Dubbed “zMOD,” the effort will help the County carry out its strategic plan to grow and diversify its economy.  The modernization plan was presented on Tuesday, March 28, 2017 at the Fairfax County Board of Supervisors’ Development Process Committee.

“We want to be sure that our ordinance is forward thinking in terms of being able to accommodate uses that we don’t know about today that will be here in the future,” said Barbara Byron, Director of the Department of Planning and Development.  zMOD will work in tandem with the County’s existing process for amending its zoning laws by prioritizing proposed changes of county-wide significance.



Executive Summary and Public Hearing Draft

Links to the zMOD Public Hearing Draft are posted below, including one annotated version with footnotes and one clean version. An Executive Summary is included in the first 49 pages, which serves as a roadmap explaining the document and the notable changes from today’s Ordinance. A hyperlinked Table of Contents begins on page 51 and can be used to navigate through the different articles. Use-specific standards are hyperlinked in the Use Tables, and references to different sections and subsections are also hyperlinked throughout the document. Following adoption, the Ordinance will be relocated into an online platform with robust search features and additional hyperlinking capabilities.

The first phase of zMOD focuses on the following goals:

  • Modernizing the permitted uses and their regulations
  • Making the Zoning Ordinance easier to understand
  • Removing gaps and inconsistencies
  • Creating a streamlined, user-friendly document
  • Using more tables, graphics, and hyperlinks
  • Being usable on multiple platforms

To help implement zMOD, the County has hired consultant services, and has added two new staff positions to work on the project.
