Indiana lead rules in brief
- Renovation and abatement rules: Indiana 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 Indiana and where the labs are
In Indiana, 1,635,863 of 2,976,568 housing units (55%) were built before 1980, rank 16 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 |
|---|---|---|---|
| Marion County | 259,353 | 59% | 8 mi: ACT Environmental Services, Inc., Indianapolis |
| Lake County | 143,422 | 66% | 29 mi: Illinois Department of Public Health State of Illinois, IDPH lab division, Chicago |
| Allen County | 91,808 | 55% | 97 mi: ACT Environmental Services, Inc., Indianapolis |
| St. Joseph County | 76,339 | 64% | 76 mi: Illinois Department of Public Health State of Illinois, IDPH lab division, Chicago |

| Madison County | 41,755 | 70% | 24 mi: ACT Environmental Services, Inc., Indianapolis |
| Delaware County | 35,987 | 70% | 41 mi: ACT Environmental Services, Inc., Indianapolis |
Over 50 miles from the nearest listed site: Allen County, St. Joseph County, Vanderburgh County, Elkhart 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 Indiana
Indiana has 4 listed lead lab sites for about 1,635,863 homes built before 1980: one site per 408,966 older homes, the 25th most stretched of 32 states with a listed site (the middle state has one per 717,498).
- 4 of the 4 sites are accredited for paint chips (paint chips scraped from walls, trim or windows).
- 4 of the 4 sites are accredited for dust wipes (dust wipes from floors and window sills, the test used after renovation).
- 4 of the 4 sites are 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.
