Hi, Just needed to get some advice. New tenants just moved in couple weeks ago -drove past the property and saw they hung up banners along the front of property (hung on tree one end to gutter other end) When i asked PM to find out what those things are, tenants got angry and defensive and told him they were prayer flags. (very colorful and obvious from street) Just wanted to see if they are within their rights to put thosr banners in front (reason i asked is before when I was renting, there were so many things we are not allowed to do) Can we ask them to take it down? They did threathen to leave if the banners were taken down, but just want to know, legally what is allowed and what is not. Thanks. The property is in WA btw.
