After lead paint remediation or renovation work on an older property, a dust wipe clearance test confirms that lead dust levels in the affected area are below the limits set by state and federal regulations before the space is reoccupied. This is a required step to close out most abatement projects and satisfy Maryland's certification requirements.

Current Lead Paint Testing Trends

  • A stricter dust-lead standard is now in effect

    Under updated EPA standards, any detectable level of lead in dust on floors and windowsills now counts as a lead hazard (the Dust-Lead Reportable Level) — a meaningful tightening from the older numerical thresholds, meaning post-work cleanup and clearance testing now have to meet a higher bar. (US EPA, cited in 2026 lead paint regulation coverage)

  • Enforcement penalties increased again for 2026

    The maximum daily civil penalty for RRP Rule violations rose to $46,989 per violation per day effective January 12, 2026, with federal enforcement priorities specifically naming painting contractors, landlords, and property managers working on pre-1978 housing. (US EPA enforcement alert, 2026)
