Ohio lead rules in brief
- Renovation and abatement rules: Ohio is not on EPA's list of states authorized to run their own RRP program, so EPA runs the RRP program there, and it has an EPA-authorized lead-based paint (abatement, inspection and risk assessment) program. (TSCA sections 402 and 404; 40 CFR Part 745) 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 lead-based paint (EPA: homes built before 1978). The counties with the most older homes, and how far each is from the nearest NLLAP-recognized lead lab:
| County | Homes built before 1980 | Share of homes | Nearest listed lab site |
|---|---|---|---|
| Cuyahoga County | 494,874 | 80% | 4 mi: Cleveland Analytical LLC, Cleveland |
| Franklin County | 306,426 | 51% | 89 mi: ALS Laboratory Group, Environmental Division (Cincinnati), Cincinnati |
| Hamilton County | 277,032 | 73% | 10 mi: ALS Laboratory Group, Environmental Division (Cincinnati), Cincinnati |
| Montgomery County | 186,023 | 74% | 36 mi: ALS Laboratory Group, Environmental Division (Cincinnati), Cincinnati |
| Summit County | 169,141 | 68% | 28 mi: Cleveland Analytical LLC, Cleveland |
| Lucas County | 146,506 | 73% | 43 mi: Accurate Analytical Testing, LLC, Romulus |
| Stark County | 119,743 | 71% | 41 mi: AT Labs., a Unit of Assay Technology, Youngstown |
| Lorain County | 82,713 | 61% | 22 mi: Cleveland Analytical LLC, Cleveland |
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. EPA’s NLLAP list prints a city but no ZIP code; a lab known only from that list is placed at its city’s most common ZIP code.

How far the labs stretch in Ohio
Ohio has 5 listed lead lab sites for about 3,353,331 homes built before 1980: one site per 670,666 older homes, the 20th most stretched of 32 states with a listed site (the middle state has one per 717,498).
- 2 of the 5 sites are accredited for paint chips (paint chips scraped from walls, trim or windows).
- 5 of the 5 sites are accredited for dust wipes (dust wipes from floors and window sills, the test used after renovation).
- 1 of the 5 sites is accredited for soil (soil from play areas and the drip line around the house).
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.
