Accessory Dwelling Unit (ADU) Primer Course

This is a non-credit course. Not for license renewals.

Increasing rates of prospective home buyers are interested in building an ADU (Accessory Dwelling Unit or what are also known as granny flats or mother-in-law apartments) on their property to provide income and housing flexibility. Real estate professionals who are on the cutting edge of this emerging development trend can best serve their clients by understanding site eligibility, development process and costs, and the return on investment of ADUs.

Attend this 3-hour training designed to help real estate professionals gain an introduction to ADU development. The course is developed and delivered by ADU guru, Kol Peterson of Accessory Dwelling Strategies LLC and author of Backdoor Revolution- The Definitive Guide to ADU Development. Kol is based in Portland, Oregon, where the epicenter of this movement has taken place and ADUs have recently surpassed single-family home construction in the city.

  • Review the demographics of current and soon-to-be ADU owners and renters
  • Understand what makes a property ADU-ready
  • Gain lessons learned from Portland's ADU-championing policies

  • Analyze cost scenarios, valuation, financing, and revenue-generating options for ADUs
