Testimonials

The most Professional people you will meet. They know what they are doing

Aimee is so personal and knowledgeable! Explains all the questions I could ever think of.

Subject matter experts on all things ADU including SB10 and AB1033 processes.

Best team to have on your side to guide you through your home renovation to improve your living conditions. Extremely professional and knowledgeable.

It’s a pleasure seeing a builder so organized with people collaborating together with purpose: to help their clients. I got a chance to see their operations as well as their leadership in the launch of the Small Contractors Association.

I’m usually stingy with five-star reviews, but Apex Homes absolutely rocks. From the first call, they treated my scattershot sketches like gold—polished the design, wrangled the permits (so I never saw City Hall), and kept every penny transparent. Throughout, the process was par excellence. I’d highly recommend them. Thanks!

Working with Aimee has been a great experience! She’s knowledgeable, really takes the time to explain the process and help guide everyone from start to finish.

Aimee Tran of Apex Homes is an excellent representative. She is very knowledgeable and professional. She comes highly recommended.

Aimee was a pleasure to work with! She was very helpful and had strong communication in helping my family figure out the best course for us.

Aimee is really helpful. She provides lots of information reviewing the my project in the initial call. Also setting up a site visit right away. She coordinated the visit with a group of professionals helping me understand the situation more clearly and what needs to be addressed. It’s a great experience working with her.

If you want to learn more about ADU options I highly recommend reaching out to Aimee and the apex team, they are soo helpful! She’s super knowledgeable and passionate about her work which shows in the way she handled all of my questions! If you have any curiosities at all with ADUs, she is the one to ask away with!

Aimee was very helpful in explaining the ADU options they offer and showing us a couple of the models available. While we didn’t move forward at this time we will certainly keep them in mind when we do decide to proceed with turning our rentals in higher cash flowing assets. Thanks Aimee!

I am very satisfied with the service provided.The process was quick and smooth, and the coordinator was highly efficient and professional.The cost was reasonable, and the outcome exceeded my expectations.The team was trustworthy, reliable, and delivered excellent results.

I attended the Apex Homes ADU Design Builder workshop and I definitely learned a lot from thepanel of speakers. Aimee spoke well and answered the attendees questions eloquently. Aimee is an attentive and a detailed oriented person. I feel confident in Apex Homes expertise with Real Estate. I am looking forward to attending the next one and learning more on this topic.

We’re planning to build an ADU in our backyard, and approached Apex since they are a preapproved builder for the city. We contacted a sales representative, her name is Aimee N. Almost immediately she set us up for a consultation session meeting with Apex team including architect, project managers, operation managers. The session was to understand our goal and what Apex has to offer. We walked through their plan and d...
