Malcolm McVickar One of the talents of the NestADU team that I appreciated the most was their ability to LISTEN! I wanted to create a custom 850 sq.ft. ADU on my property next to my house and we had to deal with a narrow site with a steep sloping back yard, so this wasn’t any place for a drop-ship prefab. Everything had to be custom-designed for my aging grandmother. Bret and John were able to take my thoughts and my Grandmother’s preferences and turn them into a very detailed, creative solution that met our requirements and create a set of drawings that got us our permit on our first submittal! Hubert Yoshida My wife and I have been married for 60 years and were looking to build an ADU on our son’s property in central California. I have cancer and was looking to provide a home where my wife would be comfortable in the event that she would have to go on without me. We needed to find a contractor who we could trust to put together a complete package, would be responsive, offer custom options to fit our needs, and be sensitive to our family dynamics since it involved my son. We talked to several contractors, and found the process to be overwhelming. Finally, we contacted John Westcott, COO of Nestadu. We met him on a zoom call and he was very warm. understanding, clear, and professional. Later he and the CEO, Bret Ashworth, showed us an ADU that they had built on a lot in Novato, and came out to our site to verify its suitability. All this was done in a week! We had problems with the site but we would definitely use Nestadu when it comes to building an ADU. Joe McGrail Great communication throughout. The process was very simple and easy- as the website had said it would be. Highly recommend. MGM Very easy to work with. Transparent pricing and quality craftsmanship. 5/5. Fran John Customer service is excellent! Seamless process! I am very pleased with the final outcome of my new ADU.

What is the difference between Custom and Prefab ADUs?
Custom:
A Custom ADU is site-built on your property to meet your exact specifications. This option offers complete flexibility in design, materials, and layout to perfectly match your vision and the existing aesthetics of your property. Ideal for unique requirements and personalized finishes.
Prefab:
A Prefab ADU is a pre-designed, factory-built unit that is delivered fully assembled to your property. This option is typically faster and more cost-effective than custom builds, with a variety of design options to choose from. Perfect for those seeking a streamlined and efficient solution.
