I think that might be a Hobo spider-- they look very similar to the Brown Recluse but so far there's no scientific evidence that they're especially harmful to humans. Brown Recluse spiders usually have larger spinnerets (butts) and the trademark "violin" marking on the top of their abdomens, and this one has neither.
The Brown Recluse doesn't do well in colder climates. They rarely make it as far north as San Jose, let alone Oregon.
