Real Stories, Real Results.
I used Urbatect for the structural review of my renovation plans. Mayank and his team were very prompt with their work for any follow up that was needed by the city as well. Overall a great team to work with. Highly recommended!
I had a wonderful experience talking with John Soliz, we then had a Zoom meeting with some of my family which proved to be professional and very informative.
I truly appreciated his time and expertise.

Great group of guys to work with. Always following up and very patient with roadblocks along the way.
As I figured out how to design my first house and needed engineering plans for my drawings, they guided me through the process so I will be able to submit to the city for building permits. Will have more plans coming their way!

Hi Milan - Thank you for your thoughtful feedback! We're really glad to hear that John made the planning process for your ADU in Richmond, CA, smooth and informative. We're excited to continue working with you and making your project a success!Thank you! 
I had a consultation with Alex Zambrano regarding building an ADU. He was very knowledgeable and understanding. He frequently stopped and asked me what questions do I have during our meeting. Did not use confusing lingo to confuse me at all during our meeting either. He did not make me feel bad at all even though my intentions were purely information on potential future ADU on a future purchase of a home with a bigger lot. If everyone at Urbatect is as friendly and patient as Alex is, the. All your clients are in great hands!!!!
