Take a look at what real property owners and builders have to say about working with QuickenPlans.
For many years I have been working with the architectural & structural engineers at QuickenPlans. Because I have been in this business for more than 40 years I can honestly let you know that you will not find a different construction document business with as much integrity, transparency, communication, and efficiency as QuickenPlans.

A couple of years ago, we worked with a local architect on a room addition plans, and it was a nightmare - constant delays, excuses, and poor performance. The worst part was that I was charged way more than it should have cost, as I found out later. So, when we decided to go for an ADU, we were very hesitant to start and obviously decided to use another company. That's when we came across the folks from QuickenPlans. QuickenPlans team delivered as promised; the plans were good, and the 3D modeling is really handy to understand what the future structure will look like. We completed our plans in 4 months (most of it was on our side - we took our time to work on the details) and are already in construction now. Highly recommend this team !

Contracted QuickenPlans to design a large deck for the front of our house. They were very diligent and provided exactly the support we required.

We interviewed multiple designers and architects for our addition project and ultimately hired QuickenPlans. It was a great experience - even though design and permitting is a lengthy and frustrating process, having QuickenPlans team was a lifesaver for us. They guided us through all the steps and demonstrated in-depth experience in navigating all requirements. I love the plans we received from them and am looking forward to seeing it built! Btw, they also connected us with a great GC they had worked with, which adds a ton of confidence when your designer and builder are working hand in hand!

I had a consultation for my room addition project with Quickenplans recently- they were recommended by my neighbor who did his addition with them. Those guys really know their stuff, very detailed and have a lot of experience with design and permitting. We're still deciding on the project but if we move forward we would go with them.

Alok K. | Fremont, CA
Our client received a violation notice from the city for an unpermitted addition. The guys from QuickenPlans helped us put together a set of plans for legalization and advised on how to address the city’s comments.
Xavier S. | Los Angeles, CA
My contractor recommended hiring QuickenPlans for our remodeling project as his designer was unavailable. It was hard for us to quickly get up to speed with all the details about the plans and permits (it is so cumbersome!), but the team did a great job guiding us through all the steps. They even coordinated the design with our contractor so we could stay on budget. They also recommended making some changes to our initial design to save on framing. While I wouldn’t want to go through the permitting process again, if I had to, I’d prefer to do it with QuickenPlans.
Joanne S. | Santa Monica, CA
We are working on a custom home design with Quickenplans. All is good so far; we hope to get through to the finish line soon.

Sathya I. | Los Altos Hills, CA
We just kicked off a big renovation and chose QuickenPlans for the design work. Honestly, I was really impressed right from our first chat. They made sense of all the zoning stuff and helped us figure out what we could do with the space. They were super patient and quick to answer our endless questions. We’re pretty excited to see everything come together with the final plans they whipped up for us!

We use them regularly for as-built plans and construction docs for our projects in the South Bay and Peninsula—they always deliver big time.
