Then use a deodorizer in the paint to help freshen up the smell, and open the windows to flush it out.I have no idea what else to do to eliminate the odor.

Is there a best way or a way to get rid of the odor and keep it away?

I plan on using Zinsser BIN primer on the floor but would like to get as much of the odor up as possible before applying. 

The odor from the porch was so strong that the upstairs tenant, who has only lived there for less than two months, had to burn incense in her apartment because of the odor.

My parents house reaked of pet urine before they moved in and after removing the carpet the entire concrete slab was spraye with Kilz and that took care of all the odor.

Yes, an ozone machine will, but to be clear, it is only neutralizing the odors - it is not eliminating the source. 

If that doesn't work, use whatever legal means are available to get rid of him as quickly as possible.For those of us in states where marijuana is illegal, we can report the odor to the police and they can handle it.

The only thing that finally killed the odor for good was Kilz oil based primer.  

The odor does seem to be worse on windy days.

The odor permeates into all of the rooms in my apt making relaxing and sleeping somewhat difficult.
