A city, and no town above it
Glen Cove is a city, and the Census Bureau treats it as its own county subdivision rather than as a place sitting inside a town. FEMA lists it as GLEN COVE, CITY OF (community status book for New York). That fact sits behind every records question here, because there is no town layer to route through. Permits, the certificate of occupancy, plumbing and electrical records and the violation history all rest with the city building department at 9 Glen Street, an address independently corroborated as city hall by the state health department's water contact list, which records GLEN COVE CITY as a community water system, identification number NY2902826, serving a listed population of 28,000. That list draws no service boundaries, so it confirms the address rather than the supply for any given house.
Eighteen register entries, seven of them Class 2
As the state's remediation site register stood on 20 September 2026, eighteen distinct programme numbers appeared under the locality the register spells "Glen Cove." The list is long, and it is a list of addresses rather than a statement about the city. Seven of the eighteen carry Class 2, which means the Department of Environmental Conservation has determined that "the disposal of hazardous waste has been confirmed and the presence of such hazardous waste or its components or breakdown products represents a significant threat to public health or the environment" (site classifications). The seven are:
- 130009, Photocircuits Corporation, 31 Sea Cliff Avenue
- 130017, Mattiace Petro Chemicals, Garvies Point Road
- 130032, Captain's Cove Condominiums, Garvies Point Road
- 130046, Li Tungsten, 63 Herbhill Road
- 130053A, Pass and Seymour, 45 Sea Cliff Avenue
- 130053B, Pall Corporation, 30-36 Sea Cliff Avenue
- 130071, Ronhill Cleaners, 71 Forest Avenue
Eleven more fill out the picture: 130028, Powers Chemco at 71 Charles Street, closed but under continued site management; a run of active brownfield and remedial entries along Garvies Point Road and Herb Hill Road; and several completed or no-further-action files, one listed under the name "K - Glen Cove (C) MGP" on Stanco St.
What none of that settles is anything about one house. Entries are pinned to street addresses and grouped by postal locality, which is not a municipal line, and the file proves it on itself: programme 130053, "Sea Cliff Avenue Industria," carries a Glen Cove locality alongside an 11579 ZIP code in the same row. Look a specific address up in the department's own database rather than working outward from a place name, then put question 18 to the seller, which asks whether petroleum or any hazardous substance has been released on the property or from it onto another.
Wastewater runs to the county, with two caveats
Beside the line the county prints as "Glen Cove City" stands the Nassau County Department of Public Works, 1194 Prospect Ave. No asterisk, no village collection layer, and the city does not appear among the thirty-four entries the same file marks "Not Publicly Sewered" (Sewer Districts by Community), though several places around it do. A Glen Cove plant is listed among the facilities in the county's sewage treatment consolidation study, yet no map exists showing whose flow arrives where, so this page attaches no plant to any address.
Nowhere in that file is a publication date printed, and the web server offers no modification time either, so how old the assignment is remains unknowable from outside. Its unit, moreover, is a community name and never a lot. Check the address in the county's land records lookup and let question 28 of the disclosure form carry the weight for the house actually being bought: public sewer, private sewer, septic or cesspool, with age, date last pumped and any known material defects.
A mixed stock, and what the mix asks of a buyer
Housing here runs to 11,462 units, the survey placing the middle of the construction range at 1960, plus or minus two years (B25035). Tenure runs close to even, with 5,656 of 11,095 occupied units owner-occupied and 5,439 rented (B25003). The structure table shows what that is made of: 5,591 detached single-family houses, 427 units in two-unit structures, 1,513 in three-and-four-unit structures and 990 in five-to-nine-unit structures, which is 2,930 units in buildings of two to nine, alongside 820 in the twenty-to-forty-nine range and 1,461 in buildings of fifty or more (B25024).
By age the city runs wide: 2,155 units from 1939 or earlier, 2,842 from the 1950s, 1,518 from the 1960s, 1,167 from the 1970s, and 1,152 built since 2010, being 792 in the 2010s and 360 in 2020 or later (B25034). Fuel oil heats 1,698 occupied units (B25040).
Every band asks something different. In a small multi-family building the questions are what divides the units, how an upper floor gets out, whether one flue is doing two jobs, and whether the unit count on the ground matches the count in the city's record. A pre-1940 detached house keeps its conversion history in the basement, and an oil-heated one brings a tank question along. A condominium or co-op purchase, by contrast, drops out of the disclosure statute altogether, since the state form excludes condominium units, cooperative apartments and property in a homeowners' association not owned in fee simple by the seller; the building's documents replace the form entirely.
Flood insurance and the map
FEMA carries the city as community 360465, first flood hazard boundary map 16 August 1974, initial FIRM 1 March 1978, currently effective map date 11 September 2009. Its record shows no Community Rating System entry, which rules out any rated discount on a policy written at a city address. No zone and no elevation for anywhere in the city belongs on a page like this one, and a Zone X label is not a clearance, because the 500-year band is drawn within it. Pull the panel at the FEMA Map Service Center and ask the seller questions 10 and 30 in writing.
