Building Code Compliance. Subject to subsection (D)(7)(b) below, all ADUs and JADUs must comply with all local Building Code requirements.

"Sales, outdoor"
means a place where a sales transaction is made outside of an enclosed building. This shall include, but not be limited to, outdoor seating, sidewalk/parking lot sales, and automotive sale lots.
