With our newly released pre-approved ADU plans, it's never been easier or more affordable to quickly build a high-end ADU in San Diego.
While building an ADU in the City of San Diego has become easier over the years thanks to friendlier building regulations, going the traditional design, permitting, and construction route still presents significant challenges.
That's why we've introduced our pre-approved San Diego ADU plans to help people homeowners or property investors quickly build a high-end ADU while saving time, money, and ultimately a ton of stress. These plans are based on our Prince House ADU project and can be customized to fit the size of your lot or any additional needs you may have for your project.
Watch the video in this section for a quick overview of what you get when you use our standard ADU plans for your project.
Once you're ready to move forward with your project, click the button below to get in touch with us to discuss what the design build process would look like using pre-approved ADU plans.
Our ADU floor plans are specifically designed to help you build an amazing ADU in a minimalist or modern style while offering you the flexibility to customize them to your lot. Make no mistake - this is anything but a cookie-cutter ADU.
We get it - the last thing you want is to end up with an ADU that looks like everyone else's.
That's why we've included several customization options (such as converting the design into a two-story duplex, adding a balcony, or scaling down the the footprint of the ADU to fit tighter lots) to allow you to end up with a one-of-a-kind ADU. And we'll be adding more customization options as time goes on.
For people with a tighter budget or those simply looking to shortcut the ADU development process, these pre-approved plans represent the best of both worlds. You can use the base framework of these ADU plans to build a modern or minimalist ADU for a reasonable cost and then customize them further to build a unique ADU tailored to your project goals.
