NYS and NYC M/WBE Certified Contractor
Most people in Wall Street don’t have trouble deciding what they want. They have trouble finding a contractor who can actually deliver it inside a converted Art Deco tower with a condo board, a landmarks committee, and a building manager who needs three forms of insurance before anyone sets foot in the elevator.
That’s the real friction here. The bathroom itself the tile, the fixtures, the layout that’s the easy part. What slows everything down is the permit filing, the asbestos assessment required before demo in any pre-1987 building, the board approval process that can take weeks on its own, and the coordination with building management on working hours and elevator access. When your contractor doesn’t know how to navigate that, the project stalls before it starts.
When you work with us a contractor who handles all of it DOB filings, ACP5 asbestos documentation, insurance certificates that meet your building’s specific requirements the experience is completely different. You get a timeline that accounts for the real process, not an optimistic guess. You get a finished bathroom that holds up, with proper waterproofing built in from the start. And you don’t spend your evenings chasing down paperwork that we should have handled weeks ago.
Green Island Group is a full-service demolition, restoration, and remodeling contractor serving New York City and Long Island. We specialize in the kind of work that Wall Street demands, because the buildings along Wall Street and throughout the Financial District aren’t typical residential construction. They’re pre-war commercial towers some of them landmarked, most of them built before 1940 that were converted to luxury condominiums over the last two decades.
That means old cast-iron pipes, non-standard drain configurations, and building materials that may include asbestos. It means your bathroom renovation requires an environmental assessment before demolition can legally begin. We handle that in-house. No subcontracting to a separate environmental firm. No gap in project management while you wait for someone else to clear the site.
From One Wall Street to the Cocoa Exchange on Wall Street Court, the buildings in this neighborhood demand a contractor who understands what they’re working with before they open a wall. That’s exactly the kind of work we do.
It starts with a real assessment not a sales pitch. We look at your bathroom, your building, and your board’s requirements together, and we give you an honest picture of what’s involved. That includes identifying whether your building falls under NYC Landmarks Preservation Commission jurisdiction, what your condo board’s alteration agreement requires, and whether an asbestos assessment needs to be completed before any demo work begins. In most Financial District buildings, it does.
From there, we handle the DOB permit filing. For a bathroom renovation involving plumbing or electrical work which is almost always the case that means an ALT-2 permit, a licensed master plumber’s permit, and an electrical permit, all coordinated under one roof. We prepare the documentation your board needs to provide formal attestation in DOB NOW, which became a requirement in January 2026. You don’t have to figure out what that means. We do.
Once permits are approved and board sign-off is confirmed, demo and construction begin. We coordinate with your building management on elevator access, material delivery, working hours, and debris removal because your neighbors didn’t sign up for your renovation. The goal is a finished bathroom that looks exactly like what you chose, installed correctly, and signed off by the city.

A bathroom remodel in Wall Street isn’t a single trade job. It’s demolition, plumbing, electrical, waterproofing, tile, fixtures, and finish work all happening inside a high-rise building with strict rules about when and how contractors can work. We coordinate every one of those trades in-house, which means you have one contact, one timeline, and one contractor accountable for the result.
Waterproofing gets particular attention here. Hurricane Sandy left a 14-foot storm surge across the Financial District in 2012, and every building manager in Lower Manhattan has had moisture management on their radar ever since. Proper waterproofing in a shower enclosure or wet floor assembly isn’t just a code requirement in this neighborhood, it’s the difference between a renovation that holds and one that becomes a building incident. We treat it as a structural priority, not an afterthought.
For compact bathrooms carved out of converted office floors which describes a lot of units in Wall Street buildings we design specifically for the space you have. Wall-mounted fixtures, floating vanities, recessed storage, and wet room configurations are all standard parts of how we approach tight layouts. The goal isn’t to make a small bathroom feel acceptable. It’s to make it feel intentional.
Yes and in most cases, more than one. A bathroom renovation in a Manhattan condo that involves any plumbing or electrical work requires an ALT-2 permit filed with the NYC Department of Buildings, a separate plumbing permit pulled by a licensed master plumber, and an electrical permit for any wiring changes. These can’t be filed by just anyone the permit application requires a Registered Architect or Professional Engineer as the Applicant of Record.
On top of the DOB filings, your condo board must formally approve the renovation before permits can even be submitted. As of January 2026, boards are required to provide attestation directly in DOB NOW before the filing is accepted. That approval process alone can take four to twelve weeks depending on your building’s board meeting schedule. Starting a renovation without understanding this sequence is one of the most common reasons projects get delayed or stopped entirely in Financial District buildings like those in Wall Street.
If your building was constructed before 1987 which covers the vast majority of residential buildings in Wall Street and the surrounding Financial District then yes, an ACP5 Asbestos Assessment Report must be filed by a licensed investigator before any demolition can legally begin. This is a New York City legal requirement, not a recommendation.
The pre-war buildings that define Wall Street Art Deco towers, Beaux-Arts conversions, early 20th century commercial buildings repurposed as condos were built during a period when asbestos was standard in floor tiles, pipe insulation, ceiling materials, and joint compounds. Skipping the assessment isn’t just a code violation; it exposes you and your contractor to serious liability. We handle the ACP5 process in-house, which means no gap between the environmental clearance and the start of demo work.
The construction phase of a full bathroom gut renovation typically runs four to eight weeks. But in a Financial District condo, the total timeline from decision to finished bathroom is usually longer often three to five months when you factor in board approval, permit filing, and inspection scheduling.
Board approval alone can take four to twelve weeks depending on when your building’s board meets and how quickly they process alteration agreement submissions. DOB permit review adds additional time on top of that. Building-specific working hour restrictions most Financial District buildings limit contractor access to weekday daytime hours also affect how quickly the construction phase moves. A contractor who gives you a four-week estimate without accounting for any of this is either unfamiliar with how NYC condo renovations actually work or is telling you what you want to hear. The real timeline includes all of it, and knowing it upfront is what lets you plan around it.
A full bathroom gut renovation in NYC typically ranges from $15,000 to $25,000 on the midrange end, and $30,000 to $75,000 or more for luxury finishes and high-end fixtures. In the Financial District, where residents are generally working with premium materials and higher-end expectations, most projects fall in the upper half of that range.
Beyond the base renovation cost, it’s worth budgeting a contingency of 15 to 20 percent above your project estimate. Pre-war buildings in Wall Street regularly turn up surprises during demolition old pipes that need replacement, non-standard framing, or materials that require remediation before work can continue. These aren’t worst-case scenarios; they’re common realities in buildings constructed in the 1920s and 1930s. A contractor who doesn’t mention contingency planning isn’t being optimistic they’re leaving you unprepared for what’s statistically likely to happen when you open a wall in a building that’s nearly a hundred years old.
Sometimes but it depends on where your plumbing stack is located and what’s directly below your unit. NYC’s building code includes what’s commonly called the “Wet Over Dry” rule, which generally restricts placing a wet zone like a bathroom directly over a dry zone like a bedroom or living room in the unit below. In office-to-residential conversions throughout Wall Street and the Financial District, this can be a real constraint because the original floor plans weren’t designed with residential plumbing stacking in mind.
That said, layout changes are often possible with the right planning. A licensed architect needs to review the existing conditions, confirm what the building’s plumbing infrastructure will support, and document the proposed changes for the DOB filing. The key is identifying these constraints before demo begins not discovering them mid-project. We assess layout feasibility during the initial walkthrough so you know what’s actually achievable before any decisions are locked in.
Everything is handled under one roof. Demolition, plumbing, electrical, waterproofing, tile, fixture installation, and finish work are all coordinated by us you’re not managing a separate plumber, a separate electrician, and a separate tile contractor who don’t communicate with each other. That single-contractor model matters more in a Wall Street condo than it would almost anywhere else, because every additional subcontractor is another approval your building management may need to process, another insurance certificate to verify, and another schedule to coordinate around building access restrictions.
The permit filing, board documentation, ACP5 asbestos assessment, and insurance certificates that meet your specific building’s requirements are all part of what we handle before construction begins. In a neighborhood where the regulatory process is genuinely complex and the buildings are genuinely unique, having one contractor who understands the full picture and is accountable for all of it is the difference between a renovation that moves forward and one that stalls at every step.
