When is an ACP 5 Form Required in NYC?

Shayan • June 11, 2025

An ACP 5 form is fundamentally required whenever you undertake renovation, alteration, modification, or demolition work in a building constructed before April 1, 1987, and that work necessitates a permit from the New York City Department of Buildings (DOB).


This core requirement applies to a broad spectrum of individuals and entities, including homeowners, contractors, developers, architects, and anyone else planning to disturb existing building materials in an older structure within the five boroughs. The overarching purpose of the ACP 5 is to formally declare that your proposed project will not disturb friable asbestos-containing materials (ACMs), or if ACMs are indeed present, that they will remain safely undisturbed throughout the scope of work.


Why Asbestos Regulations are Strict in NYC


New York City's built environment boasts a rich history, with a significant portion of its structures predating 1987. This year is a critical demarcation because it generally marks the period when asbestos was widely used in construction due to its remarkable properties, such as fire resistance and insulation. However, it's now well-established that disturbing asbestos can release microscopic fibers into the air, leading to severe and often fatal health conditions like lung cancer, mesothelioma, and asbestosis.


To safeguard the health of construction workers, building occupants, and the general public, the New York City Department of Environmental Protection (DEP) and the Department of Buildings (DOB) have implemented stringent regulations. The ACP 5 form is a cornerstone of this regulatory framework, acting as a crucial preliminary step before many construction projects can even begin.

Key Scenarios Where an ACP 5 is Mandatory


Let's delve into the specific scenarios that most frequently trigger the need to file an ACP 5:


  • Any Construction Project Requiring a DOB Permit in a Pre-1987 Building: This is the most pervasive trigger. If your project, regardless of its perceived size or complexity, requires a work permit from the NYC DOB, and the building in question was constructed before April 1, 1987, then an asbestos survey must be conducted. This survey will then dictate the necessity of an ACP 5. This includes a wide array of projects, from seemingly minor updates like plumbing or electrical system upgrades to more extensive structural changes or interior demolition.
  • Renovations and Alterations of Existing Spaces: Even if you're not planning a full-scale demolition, many renovation and alteration projects in older buildings will necessitate an ACP 5. This includes, but is not limited to, replacing drywall, flooring (especially vinyl asbestos tile), ceiling tiles, insulation (like pipe lagging or attic insulation), plaster, or disturbing caulking around windows and doors. Any activity that involves breaking, cutting, drilling, or otherwise disturbing these types of materials within a pre-1987 structure can potentially release asbestos fibers.
  • Partial or Full Demolition Work: All demolition projects, whether it's removing a single interior wall or an entire building, in structures built before April 1, 1987, unequivocally require an asbestos survey. Based on the survey findings, an ACP 5 form will be issued if no asbestos will be disturbed, or an ACP 7 form will be required if abatement of asbestos-containing materials is necessary prior to demolition.
  • Projects Where Asbestos is Identified but Will Remain Undisturbed: It's important to note that the presence of asbestos in a building doesn't automatically mean it needs to be removed. If an asbestos survey identifies ACMs in your building, but your proposed scope of work explicitly avoids disturbing these materials, a DEP-certified asbestos investigator can issue an ACP 5 form. This document certifies that, given the project plan, the asbestos will remain safely encapsulated and undisturbed.
  • Pre-Purchase or Due Diligence Asbestos Assessments: While not directly linked to obtaining a DOB permit for new construction work, an ACP 5 might be sought during real estate transactions involving older buildings. Savvy buyers or developers often request such assessments to understand potential asbestos liabilities for future renovations or redevelopment, ensuring a smoother and more informed transaction.


In essence, if your project involves physically interacting with or changing any existing building material in an NYC structure built before April 1, 1987, and you require a permit from the Department of Buildings, securing an ACP 5 form is a critical and legally mandated step. It's not merely a piece of paper; it's a fundamental element for ensuring compliance, safeguarding worker health, and protecting the wider public.

Navigating these regulations can be complex, and ensuring proper documentation is key. We offer comprehensive ACP 5 form services, providing the expertise and certified investigations needed to help you navigate these essential NYC environmental regulations efficiently.

To encapsulate lead paint, you seal it in place with a special coating that keeps the lead dust and chips from getting loose, instead of stripping everything off.

How Can I Tell if Paint Is Lead Based? Signs, Testing & Safety Tips

By Shayan Nadeem • February 23, 2026
Lead-based paint is paint that contains lead compounds as pigments or drying agents, which were widely used to make paint more durable and moisture resistant. When this paint deteriorates or is disturbed, it can create toxic dust and chips that pose serious health risks, especially to young children and pregnant women. If you’re wondering “how can I tell if paint is lead based” or “how to know if my house has lead paint,” the safest answer is that you can’t be 100% sure just by looking – you need proper testing, ideally by a certified professional .​ Why lead-based paint is a concern Lead-based paint is still found in millions of older homes and becomes dangerous when it peels, chips, or turns into dust, especially around windows, doors, stairs, and floors. Homes built before 1978 are more likely to contain lead-based paint because that’s when it was banned for residential use in the U.S. Lead dust and chips are a major source of exposure for young children, who may inhale dust or put contaminated hands or objects in their mouths. Even if everyone in the home feels fine, lead can still be present and causing harm without obvious symptoms.​ Clues your paint might contain lead These signs do not confirm lead, but they tell you it’s time to take the possibility seriously and consider testing: Age of the building: If your home or apartment was built before 1978, there may be lead-based paint somewhere in the structure.​ Location of the paint: High-friction and high-impact areas (window frames, sashes, doors and trim, stairs, railings, and floors) are common sources of lead dust when old paint wears down.​ Condition of the paint: Peeling, chipping, cracking, or “alligatoring” (paint that looks like reptile scales as it wrinkles and splits) is a classic red flag in older homes.​ Layers of old paint: Multiple thick layers of old paint on wood trim, doors, and windows in an older property may include at least one lead-based layer. These clues alone aren’t enough to say “yes, this is lead,” but they are strong reasons to get a proper inspection. Reliable ways to tell if paint is lead-based To truly answer “how can I tell if paint is lead based,” you need one of the following testing methods: EPA-recognized home test kits Available at hardware stores; you apply a chemical solution or swab to a small area of paint and watch for a color change indicating lead. Only use kits that are EPA-recognized, and follow the instructions closely for more reliable results.​ These kits can be a useful screening tool, but they are not as thorough as a professional inspection. XRF (X-ray fluorescence) inspection by a certified professional An EPA-certified lead inspector uses a handheld XRF device to scan painted surfaces and measure lead content without damaging your walls. XRF testing is fast, noninvasive, and considered one of the most reliable ways to determine whether paint is lead-based. As per Hud.gov , This method is commonly used in New York City and other jurisdictions to meet local and federal requirements. Laboratory analysis of paint samples A small paint chip is carefully collected and sent to a certified laboratory that analyzes the sample for lead content.​​ Lab testing is highly accurate but slower and may require a professional to collect samples safely so you don’t create unnecessary dust.​ According to CDC , lead paint inspection tells you which surfaces contain lead, while a risk assessment focuses on whether you have actual hazards like peeling paint and lead-contaminated dust – many homeowners choose to do both.​ For residents in the New York/New Jersey area, MJC offers professional lead paint inspections using approved methods:
