Portland Oregon Zoning

[Gene Murashko]

I am looking at a property that is in Portland  (Lents area) and since zoning varies by county and city I have a question for the experts. It has 1 house on 2 lots totaling 9200 square feet. The house according to the owner is uninhabitable. Would I be able to have a 2-over-1 duplex on a lot like this and re-use utilities? I know this is becoming more popular in the portland area because of lack of undeveloped land.
