FAQ
Do I need a building permit or historic preservation approval to install an outdoor heat pump or replace an AC condenser in Manhasset?
Yes, replacing or adding exterior HVAC equipment requires a mechanical building permit issued by the Town of North Hempstead Building Department. If your property is a Town-designated historic landmark or within a recognized historic preservation area, any work involving exterior lineset penetrations or visible outdoor machinery requires a prior Certificate of Appropriateness (COA) from the Town of North Hempstead Historic Landmarks Preservation Commission.
