FAQ
Do I need permit approval from the NYC Landmarks Preservation Commission (LPC) to install an outdoor heat pump or air conditioning condenser at my Locust Valley home?
No. Locust Valley is in Nassau County within the Town of Oyster Bay, outside NYC boundaries. The NYC LPC has no jurisdiction here. Unless your house is one of the few individually designated Town of Oyster Bay historic properties, you only need a standard mechanical/building permit from the Town of Oyster Bay Department of Planning and Development.
