This video slideshow highlights the top ADU companies that are currently manufacturing prefab ADUs (Accessory Dwelling Units) in markets within the United States. By “top”, we recognize these firms as taking unique and innovative approaches to construction in general, ADUs in particular, while having ambitious goals to deliver high quality, affordable homes within reliable timeframes.

If any of these companies are not serving your specific market, we recommend contacting them to confirm future plans, as we expect several of these companies will be expanding their distribution over the coming months and years. Additionally, look for innovative local builders that are partnering with these types of disruptive manufacturers. Many, if not most, of these vendors prefer to partner with local contractors to perform the site prep work and final installations.

Also, be sure to review our collection of ADU-related articles.
