Or a professional theater in your area may have secured rights to produce the play, barring all other local productions until its run has closed. The availability of a play can change from day to day, which is why restrictions don't appear in most play catalogs. Restrictions exist because professional producers and touring groups pay much higher royalties than nonprofessionals, thus guaranteeing them exclusivity and a certain amount of freedom from competition. As a rule, all productions in New York and Los Angeles must be cleared, so allow for extra time if your theater is located in these areas. Other major cities like Chicago, Seattle or San Francisco may require additional clearance as well. License, Rights
