Agency: Indiana Department of Environmental Management (IDEM), Office of Air Quality — Asbestos (326 IAC 14-10; licensing under 326 IAC 18)
Official program page
IDEM says that, except for residential buildings with four or fewer dwelling units, facilities must be inspected by an Indiana-licensed asbestos inspector before demolition or renovation — and that every asbestos professional in the state needs an IDEM license (IDEM Asbestos). The rest of this page is about where that line falls.
The homeowner exemption
If you own or operate a noncommercial residential building with four or fewer units, IDEM says you are not required to get an asbestos inspection, notify IDEM, hold an asbestos license, or follow the state and federal emission-control work practices. You must still follow open-burning prohibitions, solid-waste disposal rules, and local ordinances (IDEM Exemptions).
Where the exemption stops
Owners of several properties may not divide a project to qualify. Buildings that are part of larger installations or are being converted for business or commercial use, urban renewal projects, and developments involving multiple homes are not exempt (IDEM Exemptions).
Inspection for everyone else
Asbestos inspections must be performed by an Indiana-licensed asbestos inspector at all demolition and renovation operations (except exempt homes) before any activity begins — including asbestos removal or job-site preparation (IDEM Asbestos Inspections).
Notification and waiting period
Owners or operators submit State Form 44593 for all demolitions and for renovations disturbing at least 260 linear feet on pipes, 160 square feet on other components, or 35 cubic feet, then wait at least 10 working days from the postmark or delivery date. Changes of 20% or more in regulated material need a new form (IDEM Notification Requirements).
IDEM notification fees
IDEM invoices building owners and managers quarterly: $150 for removal of more than 2,600 linear feet, 1,600 square feet, or 400 cubic feet of friable regulated material; $50 for less; and $50 per structure for demolitions (IDEM Notification Requirements).
Licenses and lookup
Inspectors need an IDEM-approved course, a passed exam, and a high school diploma or equivalent (two years of relevant experience can substitute). Contractors must carry at least $500,000 in asbestos liability insurance (IDEM license qualifications). Check any license in the Indiana Professional Licensing Agency’s free Search and Verify database, linked from IDEM’s find-a-professional page.
If your Indiana home is exempt, should you still test?
IDEM’s own answer for exempt homeowners who are concerned about asbestos is to follow its homeowner guidance, consult an Indiana-licensed asbestos professional, and use EPA’s asbestos resources (IDEM Exemptions). Its homeowner guidance says materials in good condition — not peeling, cracking or crumbling — can usually be left alone, and that if homeowners decide to remove asbestos, IDEM strongly recommends professional asbestos removal contractors (IDEM homeowner guidance, PDF).
That matters most for kitchen and bath remodels, floor-tile tear-outs, and basement boiler or pipe-wrap work — the jobs most likely to disturb material. EPA says you can’t tell by looking, and that a trained, accredited professional should take samples (EPA — Protect Your Family).
Disposal still applies to homeowners
IDEM’s homeowner guidance says residential structures are exempt from the state’s special asbestos disposal requirements, but not from the general rule that no one may store, process, or dispose of solid waste in a way that threatens health or the environment — and it tells homeowners to contact their health department about local ordinances (IDEM homeowner guidance, PDF). Open burning of asbestos is strictly prohibited (What IDEM Regulates).
Schools and workplaces
IDEM does not oversee AHERA, the federal law requiring school officials to inspect schools and keep management plans — EPA does — and it does not enforce workplace safety; INSafe, part of the Indiana Department of Labor, enforces the OSHA standards that cover exposure monitoring and protection during demolition and renovation (What IDEM Regulates).
Common asbestos materials checklist
EPA and state agencies list these as places asbestos may be found. Checking a box does not mean the material in your building contains asbestos — only a laboratory analysis can determine that. Use this list to brief a licensed inspector, then request a match below.

Do I need asbestos testing in Indiana?
Answer three questions. The result cites EPA’s “don’t disturb it — use a trained and accredited professional” guidance, plus this state’s official rules. It is educational, not a legal determination.
If you are planning to remodel, do not assume the work is risk-free. EPA’s homeowner guidance says remodeling can disturb building materials and that a trained and accredited asbestos professional should take samples for analysis. EPA also says taking samples yourself is not recommended, because sampling done incorrectly can be more hazardous than leaving the material alone.
Federal Asbestos NESHAP rules require a thorough inspection where demolition or renovation will occur at a facility — structures, installations, and buildings, excluding residential buildings that have four or fewer dwelling units. Any demolition or renovation at an institutional, commercial, or industrial building is regulated; at a minimum the thorough inspection requirement applies. The owner or operator must notify the delegated agency (often the state) before any demolition, and before renovations of buildings that contain a threshold amount of regulated asbestos-containing material. NESHAP does not require regulated ACM to be removed before demolition or renovation if the total amount to be removed or disturbed is less than 260 linear feet, 160 square feet, or 35 cubic feet. Houses demolished as part of a commercial or public project are not treated as exempt. Your state can be stricter than this federal floor — read the state notes below.
EPA says that if building materials in your home are not damaged and will not be disturbed, you do not need to have the home tested for asbestos. Material that is in good condition and will not be disturbed (by remodeling, for example) should be left alone.
For an owner-occupied home, start with EPA’s rule of thumb: leave undamaged material alone, and use a trained and accredited professional if you will remodel or if material is more than slightly damaged (Protect Your Family from Exposures to Asbestos). State licensing, inspection, and notification rules can still apply when a contractor does the work or when you renovate — check your state page.
Indiana: noncommercial homes with four or fewer units are exempt from IDEM’s inspection, notification and licensing rules, but not from disposal rules, burning bans, or local ordinances (IDEM Exemptions).
Rental housing and apartments are often treated more strictly than an owner-occupied single-family home. Landlords, property managers, and contractors more often need a licensed inspector and a licensed abatement contractor. OSHA regulates asbestos in construction and general industry; Maine DEP notes that OSHA rules apply whenever an employer/employee relationship exists. Read your state’s rental and multi-unit notes on this page.
EPA’s Asbestos NESHAP page states that any demolition or renovation operation at an institutional, commercial, or industrial building is regulated, and that at a minimum the thorough inspection requirement applies. Schools have extra duties under AHERA: inspections and response actions must be done by professionals trained under EPA’s Model Accreditation Plan, and school bulk samples and TEM clearance air samples must go to a NIST NVLAP-accredited laboratory. EPA also recommends accredited labs for non-school buildings.
EPA says asbestos-containing materials that are not damaged or disturbed are not likely to pose a health risk, and that the best step is usually to leave material alone if it is in good condition. Do leave undamaged asbestos-containing materials alone, and take every precaution to avoid damaging them.
If you suspect a material contains asbestos, EPA says not to touch it. Look for signs of wear or damage such as tears, abrasions, or water damage. Damaged material may release fibers, especially if it is hit, rubbed, handled, or exposed to vibration or airflow. If the material is more than slightly damaged, or you are going to make changes that might disturb it, repair or removal by a trained and accredited asbestos professional is needed.
EPA’s homeowner don’ts include: don’t dust, sweep, or vacuum debris that may contain asbestos; don’t saw, sand, scrape, or drill holes in asbestos-containing materials; and don’t use abrasive pads or a power stripper on flooring that may contain asbestos.
