Why Mountain View Homeowners Choose Mayers CNR for Their ADU
Mountain View is one of the most active ADU markets in the Bay Area. The rental demand near Google’s campus and the downtown Castro Street corridor is consistent and strong. Lot sizes in Mountain View’s residential neighborhoods are workable for detached ADUs, garage conversions, and JADUs. The City of Mountain View Community Development Department has a clear ADU permit process and the city has adopted state ADU laws that make the path to approval straightforward. We have built ADUs throughout Mountain View — Monta Loma, Cuesta Park, Whisman Station, and beyond.
Mayers CNR is fully licensed (CA #1063024), family-owned, and has completed hundreds of projects across the Bay Area since 2012.

Real ADU Reviews
We had a great experience with Mayer’s Construction on our JADU project. The team worked incredibly fast and respected our time, minimizing how much we needed to be involved in small details. They captured our vision and we would use them again without hesitation.
Thank you Mike and Nathan for working with us on getting our home remodeled and completed. We chose Mayer’s Construction and we’re glad we did. Natalee was our designer, Mike was our project manager. Daily updates throughout. Home looks beautiful and modern exactly like we wanted.
The team exceeded my expectations with their quality of work and attention to detail. Every aspect of the project was handled professionally and the result speaks for itself. I have referred them to three neighbors already.
