What Kitchen and Bathroom Remodels Cost in Nassau County
These are ranges, not quotes; a real number comes from a measured design and a written line-item proposal.
Kitchen remodel. Most full kitchen remodels run from about $25,000 to $100,000 or more. Sweeten’s Long Island cost guide puts a complete rip-and-replace of a roughly 120 square foot kitchen at $23,500 to $102,500 or more, and cabinetry is almost always the single largest line item. Plan on 2 to 4 months of active construction. Our kitchen remodel cost guide breaks down the minor, midrange, and upscale tiers.
Bathroom remodel. A midrange full bathroom starts in the low $20,000s, close to the national midrange bath average of roughly $26,000 in Zonda’s 2025 Cost vs Value report. Powder rooms cost less, and a large primary or spa bath can reach six figures. See the bathroom remodel cost guide.
Hold a contingency of 10 to 20 percent on a kitchen and 10 to 15 percent on a bathroom, because surprises behind the walls are common in Nassau’s older housing stock, from prewar North Shore colonials to the postwar capes and ranches across the county. Decide early whether the layout stays put: moving plumbing, gas, or a wall is the biggest swing cost in both rooms and is also what triggers permits.
How Permitting Works in Nassau County: Towns, City, and Villages
There is no county-wide building permit in Nassau. The county’s Building and Zoning Permits page (nassaucountyny.gov) directs homeowners to their city, town, or village for local building permits. Dozens of incorporated villages and two cities run their own building departments, so the first question is not just which town the house is in but whether it sits inside a village. The trigger is the same everywhere: cosmetic work in place usually needs no permit, while work that moves or adds plumbing, electrical, or gas, or touches a wall or structure, does. Our Long Island permit guide covers the full rules.
Town of Hempstead
The Town of Hempstead Department of Buildings, at One Washington Street, 2nd Floor, in Hempstead, enforces the town’s ordinances on the use and occupancy of buildings and structures, with applications filed through the Town’s Online Permit Center (hempsteadny.gov). Merrick, North Bellmore, and other unincorporated communities file here; villages inside the town file with their own building departments.
Town of North Hempstead
The Town of North Hempstead Department of Building, Safety, Inspection and Enforcement, at 176 Plandome Road in Manhasset, issues building, plumbing, and rental permits through the Town’s online portal (northhempsteadny.gov). The unincorporated parts of Manhasset, Port Washington, and Roslyn Heights file here. Much of the North Shore is inside villages that permit their own work: the Village of Roslyn Building Department reviews permit applications for compliance with the New York State Building Code and Village codes and states that work without the required permits is against the law (historicroslyn.org), and the Village of Great Neck Buildings Department, at Village Hall, 767 Middle Neck Road, issues building permits and inspects projects during and after construction (greatneckvillage.gov).
Town of Oyster Bay
The Town of Oyster Bay Building Division is at 74 Audrey Avenue in Oyster Bay, with a Building Division Annex at Town Hall South, 977 Hicksville Road in Massapequa. The Town lists any interior alterations and plumbing fixtures among the work that requires a permit (oysterbaytown.com). Glen Head, the hamlet of Oyster Bay, Syosset, Jericho, and Plainview file here. The Village of Sea Cliff Building Department, at Village Hall, 300 Sea Cliff Avenue, permits its own work and spells out the triggers: structural work involving framing, new wiring, panels, or circuits, and plumbing work that cuts, solders, or connects pipes, including PEX (seacliff-ny.gov).
City of Glen Cove
The City of Glen Cove Building Department at 9 Glen Street enforces the New York State Uniform Fire Prevention and Building Codes and states that if a project involves structural changes it requires a permit, with interior structural work and electrical service changes on its list (glencoveny.gov).
Fees and review times differ by municipality, so we confirm them when we prepare your drawings. D&V files the permit in its own name; if a contractor asks you to pull your own permit, treat that as a warning sign.
The Nassau County Home Improvement License
Separately from the building permit, Nassau licenses home improvement contractors at the county level. The Nassau County Department of Consumer Affairs, also called the Office of Consumer Affairs on parts of the county site, licenses home improvement businesses under Nassau County Administrative Code Section 21-11, and the county’s consumer checklist states that it is against the law to operate a home improvement business in Nassau County without a license (nassaucountyny.gov). Homeowners can verify a license and check complaint history by calling (516) 571-2600. D&V holds Nassau license 202187 alongside Suffolk HI-71989 and NYC 2100175-DCA.
Where We Work in Nassau County
Our Nassau portfolio is concentrated on the North Shore, with completed kitchens and bathrooms in Roslyn, Manhasset, Great Neck, East Hills, Glen Head, Sea Cliff, Glen Cove, and Oyster Bay, plus South Shore projects in Merrick and North Bellmore. Examples in our project portfolio include a 2026 kitchen remodel in Merrick, an indoor-outdoor kitchen in Oyster Bay, a first-floor remodel in North Bellmore, kitchens in Great Neck, Sea Cliff, and East Hills, and bathrooms in Roslyn, Glen Head, and Manhasset. We also serve the rest of the county, from Port Washington to the Five Towns.
The showroom sits on Route 25 in East Northport, about 20 minutes east of the Nassau line by Jericho Turnpike or the Northern State Parkway. As a rough guide, Syosset and Oyster Bay are about 20 to 30 minutes away, Glen Head, Roslyn, Manhasset, Merrick, and North Bellmore about 30 to 45 minutes, and Great Neck about 40 to 50 minutes in normal traffic.
Why Design-Build Matters in Nassau County
A traditional remodel involves a designer, a materials showroom, a general contractor, and a town or village building department. Design-build puts the first three under one roof and handles the fourth.
One contract, one point of contact. Design, selections, permits, and construction are priced in a single written proposal with line-item costs, a timeline, and specified materials.
Selections in a real showroom. Cabinetry including imported Italian kitchen cabinets, countertop slabs in quartz, granite, marble, and porcelain, tile through our discount tile program, vanities, shower doors, bathtubs, sinks and faucets, flooring, custom closets, and lighting are chosen side by side, which keeps material lead times inside the schedule.
Permits handled by the builder. Drawings are prepared for the specific town, city, or village, filed under our Nassau license, and the inspection schedule is built into the construction plan.
Every project follows the same path: a free consultation with a general estimate, an in-home measurement and structural evaluation, then a detailed written line-item proposal, with a dedicated project manager through construction. Our kitchen remodeling and bathroom remodeling pages describe what each project includes.
