We were looking at ways to invest our money. My wife and I thought, why don't we build an ADU for rental income? Also, someday we can move into it. So it has multiple purposes.

When we bought our house, Kristen was pregnant and we wanted Grandma to be around to help with the baby. And then ultimately, we wanted to be around for Mom when she gets older.

We decided to build an ADU because our family's property is a big lot. That's hard to find these days, especially with the cost of housing. Plus we are closer to my mom.

I decided to build an ADU because the property was a double wide lot. I'm a half mile from the beach and could see the view from the top of my house and thought, I have to take advantage of that.

I'm a product stylist and photographer. I decided to build an ADU because my business was taking off and I was spending a lot of time outside of the home. Building a studio lets me work from home more.

Why choose a design build ADU contractor?
You may be wondering if you should start with an ADU consultant, designer, architect, general contractor or ADU builder for your guest house project. The difference with a true design build ADU construction company is that the same company and team of people will be responsible for designing and permitting an ADU house that can also be built on budget. Incentives are fully aligned with the client; the entire project must be a success and run as quickly as possible.
