Type Five

We had an excellent experience with Type Five (https://www.typefive.com/). We initially wanted a pre-fab ADU dropped onto our lot, but after many months of going down that road, the crane company said they couldn't deliver an ADU to sloping, flag-style lot. This turned out to be a blessing because we ultimately landed on Type Five who built us a much higher quality ADU in just a tiny bit more time. It is a beautiful house - and was in dwell! Their designs offer enough flexibility that we got exactly what we wanted -- a 2 bed, 1 bath, "L" shaped ADU with a living area, small kitchen, and laundry. I managed a heavy remodel 10 years ago, and this was a substantially easier experience! They communicated well with us, kept the project within the budget, and had good solutions to various challenges with our unique lot, including difficult fire sprinkler issues. I feel like we got all the benefits of a custom build, without the uncertainty. They essentially build the same structure each time, and all the subcontractors know what they are doing, so they are efficient and can accurately estimate the costs.  I encourage you to give them a hard look when considering ADU contractors!
