    William J. Thomann, Inc., Respondent, v Auburn Enlarged City School District, Appellant.
   — Order unanimously affirmed without costs. Memorandum: Supreme Court properly denied defendant’s motion for summary judgment and dismissal of the complaint.

Plaintiff failed to file the notice of claim required by Education Law § 3813 within three months of the time that the project was substantially complete (see, Castagna & Son v Board of Educ., 151 AD2d 392, 393; Public Improvements v Board of Educ., 81 AD2d 537, affd 56 NY2d 850). A question of fact exists, however, whether defendant is estopped from asserting the defense of failure to file the notice of claim (see, Welsh v Gindele & Johnson, 50 AD2d 971).

Supreme Court correctly denied the motion to dismiss the action as time-barred. The cause of action arose for Statute of Limitations purposes when plaintiff “should have viewed his claim as having been rejected” (Arnell Constr. Corp. v Village of N. Tarrytown, 100 AD2d 562, 563, affd 64 NY2d 916; see also, Central School Dist. No. 3 v Kosoff & Sons, 53 AD2d 1058, 1059). Plaintiff stated in its affidavit that it had no notice that its claims were rejected until one month before it served its complaint.
