Building a burien DADU

[RJ Albers]

Was hoping to reach out to someone who has built a DADU in the burien area. I'm currently house hacking a SFH that has potential to construct a DADU. I've been quoted 330k for a 1k square ft build from mykabin. I've heard of people turning their DADU into a condo in the Seattle area but wasn't sure if it was possible in burien. I'm trying to figure out if it's more profitable to just get another SFH househack or to build the DADU. Any info from people who have been through the process of constructing one in the area would be much appreciated.
