Sewer status and lots
Nassau's health department puts Plandome among the North Shore communities without public sewer. Plandome covers 0.5 square miles; the roughly 568 parcels touching its boundary have a median size of 0.36 acres (about 15,500 sq ft). That is the 23rd-largest median parcel of the 133 Nassau places we measured. Nearby: Plandome Manor (not publicly sewered, median parcel 0.52 ac); Plandome Heights (not publicly sewered, median parcel 0.22 ac); Munsey Park (not publicly sewered, median parcel 0.25 ac). Plandome's status on the county sewer list is community-level; parcel checks matter at village edges and for older private connections.
Grant and permits
Because the county lists Plandome outside public sewer, its homes fall in the area Nassau's S.E.P.T.I.C. grant was designed for, subject to the program's property test. Permits come from the Village of Plandome; the contractor needs a Nassau County Home Improvement License, and no county rule we found requires an I/A system for an existing home.
For Plandome properties, Nassau grant amount and no-stacking details are on the Nassau County overview and Long Island grants guide.
