It is the most common reason a demolition date slips, and almost nobody explains it before the deposit.
NESHAP stands for National Emission Standards for Hazardous Air Pollutants. The asbestos NESHAP is the federal rule that governs what has to happen before a building comes down, and in Illinois it is administered by the Illinois EPA. The two pieces that touch a normal demolition job are an inspection and a written notification.
For regulated buildings the notification has to be on file with the Illinois EPA at least ten working days before demolition starts. Ten working days is two calendar weeks, not ten days. That clock is the single most common reason somebody’s teardown date moves, and it moves for people who did not know the clock existed until the week they wanted the machine on site.
A detached single-family residence being demolished as a residence generally falls outside the regulated category. Farm buildings, commercial buildings, apartment buildings and institutional buildings generally fall inside it. That is a summary and not legal advice — the honest answer is that the building type decides it, and we walk through your specific building at the estimate rather than guessing from a web page.
A licensed inspector walks the building and samples the materials that historically contain asbestos: some old roofing and siding, pipe and boiler insulation, floor tile and the mastic under it, and certain wallboard compounds. It is not a demolition of the building, it is a few hours and some samples. Anything found that is regulated has to be removed by a licensed abatement contractor before the structure comes down.
Because it is a calendar item, not a surprise. Told at the site walk it costs you two weeks of planning. Found the morning the machine arrives it costs you the mobilization, the date, and sometimes a lot more than that. We would rather be the contractor who mentioned it in week one.
A detached single-family home being demolished as a residence generally falls outside the regulated category, which is why most house teardowns around here do not carry an inspection requirement. Farm, commercial, apartment and institutional buildings generally do. We look at your specific building at the estimate rather than assuming, because the building type is what decides it.
At least ten working days before the work starts, which is two calendar weeks rather than ten days. That clock is the most common reason a demolition date slips, and it is the reason we ask about the building age on the first call.
Anything regulated has to be removed by a licensed abatement contractor before the structure comes down. It is its own scope and its own schedule. We help you line it up and then work behind it, so you are not managing two contractors who have never spoken to each other.
An asbestos inspection has to be done by an inspector licensed by the Illinois Department of Public Health. It is not something a demolition contractor can sign off on, and we do not pretend otherwise. What we can do is tell you at the estimate whether your building is likely to need one, and hand you names of people who do it, so you are not starting that search cold.
Under the federal NESHAP rule a residential building with four or fewer dwelling units is not a regulated facility, so a duplex or a four-flat generally sits outside it the same way a single-family house does. Five units and up and it is in. That line catches people out on older rental property, which is why we ask how many units are in the building before we put a date on anything.
For friable surfacing material most inspectors work to what the trade calls the 3-5-7 rule, from the AHERA protocol: three samples under 1,000 square feet, five between 1,000 and 5,000, and seven above that. Pipe insulation, floor tile and other materials follow their own counts. It matters to you because sample count drives the lab bill and the turnaround, and both of those sit in front of your demolition date.
