A barn typically has an inhouse trainer. If that trainer does not cover certain disciplines that boarders are looking for then yes, outside trainers should be allowed. It keeps a wider variety of boarders attracted to the barn.
Our barn allows this, without fee, if it meets the above criteria. In other words there is no conflict of interest. But there is no exclusive use of the arena. As a boarder I appreciate this, because it helps keep my lesson fees lower. I understand the reasons for charging a trainer, and again I appreciate that my boarding facility doesn't. I'm sure if there was a trainer conflict or other issues with the non-resident trainer that the outside trainer would be blocked.
The barn can charge a trainer a "usage" fee, but most likely that trainer will just turn around and pass this off on your boarders who are taking the lessons.
