So the house near you will have 9 adult men in recovery... we had a sober house in our suburban neighborhood that housed a handful of women and it was not a problem at all. If they are "working the program" and are straight out of a rehab situation, I'll bet they won't give you much reason for concern. They might be standing outside on the sidewalk smoking a lot, but generally speaking, if they are staying sober, they are just living their lives and if they start drinking, someone--whoever is responsible for the sober house--will kick them out.
