Wilmer Valderrama Sued By Neighbor — STOP THE PARTYING!!

Wilmer Valderrama is either a loud, obnoxious, inconsiderate home owner … or his neighbor is a crotchety pain in the ass … this according to a new lawsuit obtained by our sources.

The former “70s Show” star is being sued by his next door neighbor Baruch Eichenbaum … who claims Wilmer has been throwing RAGERS at his L.A. home for years … and the noise is unbearable.

In the suit, filed in L.A. County Superior Court, the neighbor says he”s bothered by “ongoing and continuing loud and disturbing noises from the property” … from parties at all hours of the day and night.

Baruch also complains about constant noise from barking dogs.

Now here”s the rub — the neighbor says he”s fired off at least 7 letters to Wilmer and has made dozens of phone calls to the actor to no avail. Baruch says he”s also called the police on several occasions … and even contacted animal control about the dog barking.

But Wilmer”s parties don”t stop … allegedly … and Baruch claims the shindigs interfere with his sleep. 

Baruch wants a judge for order WIlmer to pipe down …AND he wants unspecified monetary damages. A rep for Wilmer had no comment.
