NYS and NYC M/WBE Certified Contractor
Most of Ridgewood’s housing stock was built between 1905 and 1915. That’s not a fun fact it’s a legal reality. Before a single wall comes down, New York City requires a certified asbestos assessment and a completed ACP-5 form from a DEP-certified investigator. Without it, the DOB won’t issue your demolition permit. Period. When you work with a contractor who handles both the asbestos side and the demolition side in-house, that step doesn’t stall your project. It just gets done.
The other thing that gets resolved is the party-wall problem. Ridgewood isn’t a neighborhood of detached ranch houses with open yards on either side. Your building shares walls, foundations, and utility connections with your neighbors. A crew that doesn’t understand attached rowhouse construction in a dense urban block isn’t just slow they’re a liability. We know exactly where one structure ends and another begins, and we work accordingly.
If your project is tied to flood damage, a burst pipe, or fire which in Ridgewood’s aging infrastructure is more common than most people expect having a contractor who works directly with your insurance carrier means one less thing you’re managing during an already stressful situation. The claim gets handled. The work gets done. You move forward.
Green Island Group has been operating across New York City and Long Island for over 12 years, with more than 5,000 completed projects across the state. We’re not a franchise. We’re not a referral network. We’re a licensed demolition and certified asbestos abatement contractor meaning the same company that assesses your building for hazardous materials is the same company that tears it down and clears the site.
We already know Ridgewood. Our team has been handling flood restoration and water damage work in the neighborhood’s pre-war buildings for years the kind of work that puts you inside century-old plumbing systems, horsehair plaster walls, and basements that weren’t designed for today’s storm loads. That experience matters when you’re pulling a demolition permit in a neighborhood with four NYC Landmarks Preservation Commission-designated historic districts and a DOB that doesn’t move on incomplete paperwork.
Our 4.7-star rating across 33 verified reviews reflects what consistent, accountable work looks like over time. Reviewers name the crew, describe the project, and talk about outcomes not just general satisfaction.
It starts with a site assessment. Before anything else, we evaluate the structure its age, its condition, what’s shared with adjacent buildings, and what’s hiding behind the walls. In Ridgewood, that last part is never a formality. Buildings constructed in the early 1900s routinely contain asbestos pipe insulation, lead paint, and materials that require certified handling before demolition can legally begin.
From there, a DEP-certified asbestos investigator completes the required ACP-5 assessment. If asbestos-containing materials are found, abatement is completed and documented before any demolition work starts and the NYC DEP is notified at least seven days in advance, as required. If the building is clear, that documentation goes straight to the DOB permit application. We manage all of this in-house. You’re not coordinating between two separate companies or waiting on a subcontractor to finish their piece before yours can start.
Once permits are issued, demolition proceeds according to the approved scope whether that’s a full teardown, a selective interior gut, or a partial structural removal. Debris is removed and the site is cleared to a condition ready for whatever comes next. If your project involves an insurance claim, we document everything the carrier needs and handle the billing directly. From the first call to a cleared site, you have one point of contact.

Demolition in Ridgewood isn’t one-size-fits-all, and we don’t treat it that way. Full building demolition, selective interior demo, gut renovations, basement ripouts, partial structural removal the scope depends on your property, your goals, and what the building actually requires once it’s been properly assessed.
Every project in Ridgewood begins with the mandatory asbestos survey because there’s no legal path around it. Buildings in this neighborhood predate the asbestos awareness era by decades, and the NYC DEP’s rules are clear: if asbestos-containing materials will be disturbed, they have to be identified and addressed before work begins. We perform that assessment in-house, which means no scheduling gap between the survey and the abatement, and no abatement-to-demo handoff delay between two separate companies.
For properties in or adjacent to Ridgewood’s historic districts including the Stockholm Street Historic District and the Central Ridgewood and Ridgewood South LPC-designated areas we account for any required Landmarks Preservation Commission review before the DOB permit process moves forward. If you’re on a block of the yellow face brick rowhouses that define this neighborhood’s architecture, that’s not a complication it’s just part of the process, and it’s one we’ve navigated before. Utility disconnection coordination, debris removal, and site clearance are included. You don’t manage the pieces we do.
Yes and it’s not optional. New York City requires a completed ACP-5 Asbestos Assessment Report, signed by a DEP-certified asbestos investigator, before the NYC Department of Buildings will issue a demolition permit. This applies to every building, regardless of size or scope of work. In Ridgewood specifically, where the overwhelming majority of residential buildings were constructed between 1905 and 1920, the likelihood of finding asbestos-containing materials is extremely high. Original pipe insulation, floor tiles, roofing materials, and plaster compounds from that era routinely contain asbestos.
If the assessment finds asbestos-containing materials, abatement must be completed and the NYC DEP must be notified at least seven days before abatement activities begin. Only after that documentation is in order can the demolition permit move forward. Working with a contractor who handles both the asbestos assessment and the demolition in-house like we do means this step doesn’t create a scheduling gap or delay your project. It’s built into the process from the start.
Residential demolition costs in New York City generally range from $6,000 to $25,000 for a standard structure, but the real number for a Ridgewood project depends on several factors specific to this neighborhood. The age and size of the building matter, but so does what the asbestos assessment turns up. If abatement is required before demolition can begin, that adds cost though having one contractor handle both eliminates the markup that comes with subcontracting the hazmat work to a third party.
Attached rowhouse construction also affects cost in ways that detached suburban teardowns don’t. Party walls, shared foundations, and the precision required to demolish one unit without disturbing an adjacent occupied building all factor into the scope and timeline. NYC DOB permit fees are calculated based on street frontage multiplied by the number of stories at $0.25 per unit, with a minimum fee of $250. The most accurate way to understand your specific cost is a site assessment we provide written estimates that spell out scope, permit costs, debris removal, and timeline so there are no surprises once work begins.
Full demolition of a landmarked building in New York City is extremely rare and requires NYC Landmarks Preservation Commission approval, which is almost never granted for outright teardowns. However, most demolition projects in Ridgewood’s historic districts involve partial demolition, selective interior work, or gut renovations and those projects have a clearer path forward. The key is understanding which type of LPC review applies to your specific property and scope of work before you file anything with the DOB.
Ridgewood has four LPC-designated historic districts Stockholm Street, Ridgewood North, Ridgewood South, and Central Ridgewood plus ten districts listed on the National Register of Historic Places. If your property falls within or adjacent to any of these areas, LPC review is typically required before the DOB permit process can be completed. A contractor unfamiliar with this layer of the process can inadvertently trigger stop-work orders or violations that cost far more than the permit fees they were trying to avoid. We account for LPC requirements as part of the standard permit process for any Ridgewood project where it applies.
If your demolition is the result of flood damage, a burst pipe, fire, or storm damage which in Ridgewood’s aging pre-war housing stock is a common trigger the insurance side of the process doesn’t have to be something you manage separately from the physical work. We work directly with insurance carriers, document the damage and scope in the format carriers require, and bill insurance directly on your behalf.
This matters in Ridgewood specifically because the neighborhood’s infrastructure vulnerabilities are well-documented. High water tables, aging storm drainage systems, and original plumbing in buildings over a century old create recurring conditions for emergency water and fire damage events. When a basement floods at 2 a.m. or a pipe fails in February, the last thing you need is to coordinate between a demolition crew, an adjuster, and a separate remediation company. Having one contractor who handles the assessment, the demolition, and the insurance documentation keeps the process moving and reduces the administrative load on you during an already difficult situation.
The honest answer is that the timeline depends heavily on how prepared your application is when it’s submitted. A complete, well-documented filing including the ACP-5 asbestos assessment, utility disconnection confirmations, and any required LPC approvals moves through the DOB review process significantly faster than an incomplete one. Incomplete applications are the most common cause of permit delays in New York City, and they’re entirely avoidable with the right preparation upfront.
For a standard residential demolition in Ridgewood, a well-prepared application can move through DOB review in a matter of weeks under normal processing conditions. Projects that require asbestos abatement add the mandatory seven-day DEP notification window before abatement can begin, which needs to be factored into your overall timeline. Properties in or adjacent to Ridgewood’s LPC historic districts add an additional review step that should be initiated early in the process. We manage the permit application from start to finish the goal is to submit it right the first time so you’re not waiting on a correction notice to restart the clock.
Yes in ways that matter a lot in Ridgewood’s housing stock. A full teardown removes the entire structure down to the foundation. Selective interior demolition sometimes called a gut renovation demo strips the interior of a building down to its structural bones while the exterior walls, roof, and foundation remain. In Ridgewood’s attached rowhouses and six-family walk-ups, selective interior demo is often the right approach because the exterior masonry is structurally sound and, in many cases, architecturally protected.
The technical demands are different too. Removing plaster, lath, flooring, fixtures, and non-structural walls from a 110-year-old building without compromising the structural integrity of the remaining shell or the adjacent occupied building on the other side of a shared wall requires a level of precision that a general demolition crew without urban rowhouse experience may not have. The asbestos survey requirement applies equally to selective interior work, since disturbing walls, floors, and ceiling materials in a pre-1920 building carries the same regulatory exposure as a full teardown. We handle both scopes, and the process assessment, permits, abatement if needed, physical work, and site clearance follows the same structured approach regardless of whether you’re gutting one floor or taking down the whole building.
