Manufactured Homes as ADUs

A comprehensive look into manufactured homes as an affordable ADU option

Close More

Join us for this special edition 1.5 hour training on the possibilities of manufactured homes as an affordable option for ADUs. 

Manufactured Homes have been around for decades, and have evolved with the times. They are banned in some jurisdictions from being an ADU due to legacy zoning codes. But, where they are allowed to be built and installed as ADUs, they offer an affordable and streamlined way to add one to a property. All of California allows for HUD manufactured homes as ADUs. 

Join us to hear from one of the top teams in building manufactured homes as ADUs, Crest Backyard Homes based in the San Diego region, as they provide an overview of how this building type can meet the needs of homeowners looking for a relatively affordable, quick, prefab ADU option.

You will learn about the financing, appraisals, construction, and delivery of manufactured ADUs as a cost-effective housing solution.

This 1.5 hour class is designed for building professionals, architects, real estate, agents, contractors, developers, and anyone interested in implementing creative solutions in the growing ADU industry.


The webinar will conclude with a 30-min Q&A session with our instructors:
