This special edition ADU class is for attendees of the Build Small, Live Large ADU Tour. We will be referencing the ADUs that were on the tour, scheduled for Saturday, June 22nd. You must purchase tickets for that event separately at

Class Description

The goal for this class is to help you, the homeowner, build an Accessory Dwelling Unit (ADU) that will augment your property, maximize your space, and add flexibility to your life. This class will help you understand the essential elements of the ADU process from start to finish, which will result in a more beautiful space and will save you time and money.

The process of building an ADU can be complex, overwhelming and expensive. I am not a general contractor or an architect trying to sell you my services. I am a professional with subject matter expertise in ADUs and a lot of practical information to share about them.


You’ll Walk Away from the Class Understanding…

·The design, permitting, and building process

·Relevant green building approaches and certifications

·Financing, rebates, incentives, cost-saving design/build measures

·Resources, references and contacts to help you design and build your ADU

You’ll be able to ask questions of me and other attendees, and network with other local homeowners who are considering building an ADU. 

Attendees will also receive a copy of my book, Backdoor Revolution- The Definitive Guide to ADU Development, which will serve as reference of the content that we cover. 


· Registration cost is $95. You can register from this page.


·The course will go from 9:30am to 1:30pm with a 30-minute lunch break. The class is going to be a fast-paced course that will cover lots of material. Be prepared with questions and be ready to take notes.
