Usmagazine.com did not say how Goldstein died, but noted he has a history of depression and drug addiction.
TMZ cited unnamed sources as saying prescription pill bottles and a pipe commonly used to smoke drugs were found near his body Friday afternoon.
His body was discovered by firefighters after a concerned friend notified police after being unable to get in touch with Goldstein, TMZ said.
Goldstein and Blink-182 drummer Travis Barker survived a plane crash that killed four others last year.
Sources told the entertainment news Web site Goldstein was sober for about nine years but had been suffering from post-traumatic stress related to the crash and was recently dumped by a girlfriend.
