Webinar Overview

Many communities throughout Washington State are grappling with a housing supply problem, with construction of new accessory dwelling units (ADUs) being viewed as one part of the broader solution. ADUs have been around for decades in many parts of Washington, and state law requires a significant number of our state’s cities and counties to have adopted regulations encouraging new ADUs in single-family zones.

The number of ADUs created in accordance with local standards has remained relatively low, however, due in part to the difficulty in meeting those regulations and the associated costs related to them. This webinar will highlight four local governments that have revised their regulations and programs, in order to increase the construction of new ADUs.

Educational Objectives

This webinar will provide valuable information on:

  • Innovative local ADU regulations and programs, both for attached (AADUs) and detached (DADUs) dwelling units
  • How ADUs can fit into a community’s vision, comprehensive plan, and Housing Action Plan to address the wide array of housing needs
  • Examples of regulatory and non-regulatory strategies that effectively encourage the production of ADUs
  • Early results of increased ADU construction resulting from innovative local ordinances and programs
  • Tips on how local governments can reduce the cost of building ADUs for both homeowners and contractors

Who Should Attend?

City and county planners, housing planners, building officials, city managers, elected officials, and other people interested in housing and growth management.

There she worked to update the Housing Element of the Comprehensive Plan, created an implementation plan for the element, and drafted updates to the County’s accessory dwelling unit code. Since starting with the City of Langley a year ago, she inherited a number of recent innovative changes to the City’s code intended to encourage a greater diversity of housing types; one of those being updates to the City’s accessory dwelling unit code, which has proven quite effective so far.
