Asbestos testing labs in Ohio

Ohio asbestos rules in brief

• Who runs the program: Ohio EPA runs both the asbestos demolition/renovation notification program and the licensing and certification of asbestos companies and individuals. (OAC 3745-20; OAC 3745-22) source
• Licensing: Ohio EPA licenses and certifies asbestos companies and individuals; only a certified Ohio Asbestos Hazard Evaluation Specialist may inspect for asbestos, and contractors disturbing more than 50 square or linear feet of RACM on any structure must be Ohio EPA licensed. (OAC 3745-22) source
• Notice before work: When Ohio requires notification, the form must be postmarked or hand-delivered (not faxed or emailed) 10 working days before the demolition or the work that will disturb asbestos; Ohio EPA prefers electronic submission through its eBusiness Center. Every demolition of a 'facility' needs notification even if no asbestos is present; a residential building with four or fewer dwelling units is not a facility unless it is part of a larger installation. For a private single-family home, no notification is needed when the homeowner does the work, but a contractor who disturbs more than 50 square feet or 50 linear feet of regulated asbestos-containing material makes the job subject to notification and must be licensed by Ohio EPA. (OAC 3745-20; OAC 3745-22) source
• Homeowners: A homeowner who does the demolition or renovation of their own private single-family home does not have to file a notification; converting the home to commercial use, or a home that was ever a business, stays subject to the rules. source

Older homes in Ohio and where the labs are

In Ohio, 3,353,331 of 5,292,391 housing units (63%) were built before 1980, rank 7 of 45 states and DC by that share (Census ACS 2020–2024, table B25034). Homes of that age are the ones most likely to contain asbestos-containing materials such as insulation, flooring and popcorn ceilings. The counties with the most older homes, and how far each is from the nearest NVLAP-accredited asbestos lab site:

Over 50 miles from the nearest listed site: Franklin County. Many labs accept samples by mail; ask before you ship. Distance runs from the county’s centre (mean of its ZIP-code points) to the lab’s ZIP-code point, in a straight line.

How far the labs stretch in Ohio

Ohio has 3 listed asbestos lab sites for about 3,353,331 homes built before 1980: one site per 1,117,777 older homes, the 3rd most stretched of 35 states with a listed site (the middle state has one per 455,948).

• 3 of the 3 sites are accredited for material samples by PLM (pieces of popcorn ceiling, vinyl floor tile, pipe wrap or other building material).
• 2 of the 3 sites are accredited for air samples by TEM (air samples, such as the clearance test after asbestos removal).

Counts from the accreditation list; homes from Census ACS 2020–2024 (B25034). A site count, not capacity: one lab can process many samples, and many accept samples by mail.
