Short answer is no.
OAR 918-305-0000:
Existing Electrical Installations
Wiring installation in existing buildings in the State of Oregon that complied with the minimum electrical safety code standards, National Electrical Code or Oregon Electrical Specialty Code in effect at the time of installation shall not be considered in violation of the current minimum Electrical Specialty Code standards, unless the use or occupancy of the building is changed requiring different methods, alterations, or additions.

The thing I run into in older homes on a frequent basis that does not comply
'with Code in effect at the time of installation' is if someone installed grounded outlets or replace lighting fixtures on old ungrounded NM cable without protecting the circuit with a gfci or running a ground.
Then they will require those things to be brought up to code.
