OCEANSIDE, N.Y. (CBSNewYork) – Town of Hempstead residents beware.

A local private company that processes building permits for homeowners is apparently trying to pull a fast one on Sandy victims who are working to rebuild their homes, Town Supervisor Kate Murray said.

My Expediter, LLC mailed out a deceptive document featuring an official town seal promoting its fee-based permit processing services to Oceanside homeowners, WCBS 880′s Sophia Hall reported.

“They took an official Town of Hempstead letterhead and put their advertisement saying that for $499 they would process the permits,” Murray said.

Sandy victims do not need to use any service for permits.

“There is absolutely no permit fees,” Murray said. “We have waived them all for renovations or rebuilds following Hurricane Sandy.”
