Meadowcreek Neighborhood Association

Could someone tell me the type of people that the group home on Shady Meadow and Forest Creek services. I live about five doors down from it and the person that I saw lock on the porch yesterday made me feel a little unsafe.  Are there any rules about group homes moving into your neighborhood?  When I worked at Martin Luther Homes in San Antonio the company had to inform the neighborhood of the people mental level and they also had to see if the neighbors wanted the home in their neighborhood.
