Accessory Dwelling Unit aka "ADU", Granny Flats, Backyard Cottage

[John Arendsen]

I'm looking for information regarding existing companies that specialize in Accessory Dwelling Units in the Southern California area. I am a general and manufactured home contractor, real estate broker and developer looking for existing lines of products to market in the San Diego, Riverside and Orange County areas. 

If a manufacturer we would be seeking an exclusive licensing arrangement as we have a marketing, advertising and sales plan that we will be implementing in 2017. We are not new to this industry and have designed and built many of these structures over the years and currently own several.
