A milestone date in the City of Hood River’s short-term rental regulations will arrive on Friday.  That will mark the seventh anniversary of their adoption, and that will end the amortization period for 60 licenses that involved pre-existing non-conforming uses.  City Planning Director Dustin Nilsen says those primarily involved home ownership and primary residency.  Nilsen said all affected license holders have been notified by mail.  He added that this marks the end of the implementation phase of the STR licenses.
