In an action to recover damages for personal injuries, the plaintiff appeals from so much of an order of the Supreme Court, Nassau County (Cozzens, Jr., J.), dated June 20, 2005, as granted that branch of the defendant’s cross motion which was for summary judgment dismissing the complaint.
Ordered that the order is reversed insofar as appealed from, on the law, with costs, and that branch of the cross motion which was for summary judgment dismissing the complaint is denied.
Thereafter, the plaintiff moved for leave to enter judgment upon Building’s default, and Building cross-moved, inter alia, for summary judgment dismissing this action on the ground that it was the plaintiffs employer and this action was barred under the relevant provisions of the Workers’ Compensation Law. Insofar as is relevant to this appeal, the Supreme Court granted that branch of the cross motion which was for summary judgment dismissing the complaint, finding that the Electrical corporations and Building “functioned as an alter ego of each other or as joint venturers.” We reverse.

Roosevelt Ave. Corp., 207 AD2d 388 [1994]).
Here, although Building’s proof established that it and the Electrical corporations were related entities, its proof failed to demonstrate anything other than that it and the Electrical corporations may have all been working at the Home Depot store on the same demolition project and that they may have had some owners in common and/or their offices at the same street address. This was insufficient to establish as a matter of law that the plaintiff should be barred from proceeding against Building by virtue of the applicable provisions of the Workers’
