North Carolina lead rules in brief

• Who runs the program: The NC Health Hazards Control Unit certifies people and firms doing lead-based paint management (abatement) and renovation work. source
• Renovation and abatement rules: North Carolina is EPA-authorized to run its own RRP program, 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
• State rule to know: North Carolina requires certification and permits for paid renovation, repair and painting projects that disturb lead-based paint in housing and child-occupied facilities (daycares, preschools, etc.) built before 1978.

Older homes in North Carolina and where the labs are

In North Carolina, 1,661,792 of 4,895,668 housing units (34%) were built before 1980, rank 40 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:

Over 50 miles from the nearest listed site: Cumberland County, Buncombe 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.
