How would the Odessa Kopbusters decoy operation translate to Portland?

Professor Bogdanski links to this story about a reality program called Kopbusters and a stunt it pulled in Odessa, Texas.  The producer rented a house, covered the windows, and installed a grow light above two small tree seedlings.  According to the producer, 24 hours after he turned on the grow light, the Odessa police obtained a search warrant and raided the house last week, looking for the marijuana.  They didn't find any marijuana, but they did find the live surveillance cameras and a poster explaining that they had been set up. 

Though there are a few holes in Kopbusters' explanation of what it did, it's still a delightful story.  It did give me this cheeky idea: if I announced that I intended to build some condominium towers and a center for high-tech research in Portland, how long would it be before the City came around to me with a trolley and a handout?
