knew owner, do i tell the old tenants to ditch the jungle gym?

[John Summerhays]

hello i'm a new investor with my first rental property in Easton PA, taking over management the old landlord allowed the current tenants to keep a trampoline and a jungle gym in the yard which i'm against. The tenant is okay with removing the trampoline but is against getting rid of the jungle gym claiming that its her tenant right to keep her property there because she pays for the yard. she has yet to sign my new lease and the previous "management" never had an official lease explaining such discrepancies. Im mostly just afraid of her kids or neighbors getting hurt and starting a lawsuit

is it within my right as the current owner to tell her to remove the jungle gym? or am I better off leaving it and writing it into my lease that i wont be held accountable for any injuries?
