Suppose that Shoepke wants to file a trespass lawsuit against some teenagers who continually throw Frisbees over his land. Shoepke discovers, however, that when the city put in the Frisbee golf course, the neighborhood homeowners signed an agreement that limited their right to complain about errant Frisbees. What is this type of promise or agreement called in real property law? 

Vern Shoepke purchased a two-story home from Walter and Eliza Bruster in the town of Roche, Maine. The warranty deed did not specify what covenants would be included in the conveyance. The property was adjacent to a public park that included a popular Frisbee golf course. (Frisbee golf is a sport similar to golf but using Frisbees.) Wayakichi Creek ran along the north end of the park and along Shoepkes property. The deed allowed Roche citizens the right to walk across a five-foot-wide section of the lot beside Wayakichi Creek as part of a two-mile public trail system. Teenagers regularly threw Frisbee golf discs from the walking path behind Shoepke’s property over his yard to the adjacent park. Shoepke habitually shouted and cursed at the teenagers, demanding that they not throw objects over his yard. Two months after moving into his Roche home, Shoepke leased the second floor to Lauren Slater for nine months. (The lease agreement did not specify that Shoepke’s consent would be required to sublease the second floor.) After three months of tenancy, Slater sublet the second floor to a local artist, Javier Indalecio. Over the remaining six months, Indalecio’s use of oil paints damaged the carpeting in Shoepke’s home. Using the information presented in the chapter, answer the above question.
