You might want to check with the city before you get in trouble PDX regarding variances, definitions of “mobile” and such. Your structure is definitely not to local code.

Now, with all of the building going on here in Portland, you MIGHT be able to get away with an unpermitted structure. The inspectors are awfully busy and all, but if they happen by your jobsite and notice it and recall that they don’t have anything on the books there, they might just stop. Then you will be looking at fines as well as tearing your structure down. Also worth considering is that getting any subs (like electricians) to work on an unpermitted structure is going to be a little harder.
