Have you built an ADU in Unincorporated Contra Costa County and/or Walnut Creek?

[Julian Martinez]

Hey y'all- 

I'm in the process of converting a workshop on our property into an ADU, and would love to chat with someone local who's done this or something similar.

The property is in the City of Walnut Creek, but our address is technically in unincorporated Contra Costa County, so all of my permitting and inspections are being done through Contra Costa County. 

Our plans have been stamped by County Planning, Fire Protection District and Central Sanitation, and we're currently under review with County Building. I'm going through underwriting with Renofi for the financing. I've signed with a contractor (Modern Green Construction) to develop the ADU, I was referred to them by working with Realm Home. So I've talked to lots of folks who will help me get this done, but no one who has actually done it themselves.

I'd appreciate the chance to speak with someone who's done this- ADU development- in this area, either in the City of Walnut Creek specifically and/or someone who's had to experience with being in an unincorporated county area in general.

Thanks in advance, it's so great to have this community as a resource!
