Asbestos Survey and Testing Requirements in Indiana
A plain-English guide for property managers, owners, and contractors: when a survey is legally required, what the process looks like, and what documents you need to keep on file before renovation or demolition begins.
Any renovation or demolition that could disturb suspect material
Buildings constructed or renovated before the 1990s should be treated as suspect until tested. The requirement is triggered by the work, not by the age of the building alone.
- Before demolition of any regulated facility, including partial demolition
- Before renovation that will disturb walls, flooring, ceilings, or mechanical insulation
- Before roof tear-off on older commercial structures
- During due diligence on a commercial or multi-family acquisition
- After water, fire, or storm damage in a pre-1990 building
- When a tenant build-out touches existing floor tile, mastic, or plaster
What an asbestos survey actually involves
1. Define the scope of work
The inspector needs to know exactly what will be disturbed — a single tenant suite, a roof replacement, or a full demolition. Scope drives how many samples are required and what the report has to cover.
2. Walkthrough and material identification
A licensed inspector walks the building and logs suspect materials: floor tile and mastic, pipe and boiler insulation, transite panels, roofing felt, joint compound, plaster, and ceiling texture.
3. Sampling
Bulk samples are collected in homogeneous groups following AHERA sampling counts, then sealed and chain-of-custody tracked to an accredited lab.
4. Lab analysis
Samples are analyzed by polarized light microscopy. Anything above one percent asbestos is a regulated asbestos-containing material.
5. Written report
You receive a report with sample locations, lab results, material condition, and recommendations. This is the document your general contractor, lender, and IDEM will ask for.
6. Notification and abatement, if needed
If regulated material will be disturbed, an IDEM notification is filed and licensed abatement is scheduled before the renovation trade goes in.
What to keep on file
If IDEM, a lender, or an insurer asks, these are the records that prove the work was done correctly.
- The inspection report with sample map and lab results
- The inspector's Indiana license number
- Lab accreditation documentation
- IDEM notification, when abatement was required
- Air clearance results after abatement
- Waste manifests showing licensed disposal

Common questions about asbestos testing
What is an asbestos survey?
An asbestos survey is a documented inspection of a building by a licensed inspector who identifies suspect materials, collects samples, and has them analyzed by an accredited lab. The result is a written report listing each material, its location, its condition, and whether it contains asbestos.
Is an asbestos survey required before renovation or demolition in Indiana?
Under the federal NESHAP rule, enforced in Indiana by IDEM, a thorough inspection for asbestos is required before most renovation and all demolition work on regulated facilities — which includes commercial buildings and multi-family properties with more than four units. The inspection is required even if you expect to find nothing.
How long does testing take?
Sampling on a typical commercial floor takes a few hours. Standard lab turnaround is two to five business days; rush analysis is usually available when a demolition date is fixed.
What happens if the survey finds asbestos?
Not every positive result requires removal. Material in good condition that will not be disturbed can often be managed in place. If the work will disturb it, licensed abatement with containment, air monitoring, and manifested disposal is required before the renovation proceeds.
Do I need a separate survey for each building?
Yes. A survey covers a defined structure and scope of work. Adjacent buildings, later phases, and areas not accessible during the original inspection need their own sampling and documentation.
Who can perform asbestos testing in Indiana?
Inspections must be performed by an Indiana-licensed asbestos inspector, and samples must be analyzed by an accredited laboratory. Ask for the inspector's license number and the lab's accreditation before work begins.
