Glen Cove is one of Nassau County's two cities, so it isn't part of any town. Its Building Department enforces the City's own building code and zoning chapters along with the New York State codes. Its own rule of thumb is: "if it involves structural changes, it requires a permit." The City moved its permits onto OpenGov in late 2024, so most filings now go online.

The City's own list of work that needs a permit includes additions (garages, porches and decks), structural interior work, finished basements, pools deeper than 18 inches (a half in-ground pool counts as in-ground), sheds including prefab sheds, wood and gas stoves and fireplaces, roofing, siding and replacement windows, signs, demolition, electrical service changes, A/C units and generators, PODS storage units, and home occupations. Fences, tree removal, tents and solar have their own applications.

• Applications go through OpenGov. The City's portal takes Building, Plumbing, Gas and A/C/Generator applications online.
• Open permits come first. The City's checklist says any open permits must be closed before it will consider new work on the property.
• Plans and survey. Building applications need signed and sealed drawings from a licensed architect or engineer, a PDF copy, and a survey that shows current conditions. Plumbing must be filed with the building application by a plumber licensed in Glen Cove.
• Certificate of Existing Use (CEU). If you're legalizing (maintaining) a dwelling, the City requires a CEU application. If the Building Department decides the evidence doesn't show the layout predates 1953, you'll need applications to maintain the structures as they are now.

The City says it plainly: if you sell a home that was modified without a permit, you'll need an architect or engineer, a permit for the work, and an inspection, and that can hold up the closing. Many lenders also want proof of a final inspection. The City asks homeowners to deal with this before they list, and we agree. Fixing it early is far easier than fixing it with a buyer waiting.

• OpenGov filings and CEUs. We pull the property's records, close old permits first (as the City requires), and handle the CEU or legalization filing and the review comments through to the final inspection.
• Free consultation and quote. We tell you what the City is likely to ask for before anything is filed.
• Typical timing: about 2–4 weeks for simple jobs (sheds, fences, decks, pools) and 4–8 weeks for more complex jobs. It varies by municipality and scope, and it's never guaranteed.
• Zoning variances: if the work needs one, we refer you to a zoning/land-use attorney and keep the permit side moving.

Call or text 516-399-0139. We usually get back to you within an hour or two. Open Monday–Friday, 8:30am–8:30pm. Weekend messages are returned by Monday.
