Renewal cycleEvery 2 years
CE requiredNone
Bond / suretyNot applicable — a credential/certification, not a contractor license.
InsuranceNot applicable.
Renewal details, what you'll need & where to file
About the CE rule:
Renewal is a refresher, taken before you expire NOT CE — renewal is an MDE-accredited refresher, and MDE guidance is that a refresher may only be taken BEFORE the prior accreditation expires; once expired, the INITIAL course is required again. Two-year cycle (federal EPA RRP is five — these are separate clocks, not alternatives).
Four credentials — which you need depends on the work WHICH ACCREDITATION YOU NEED DEPENDS ON THE WORK, and this entry does not decide that for you:
  • renovation/repair/painting on pre-1978 housing is the FEDERAL EPA RRP credential — Maryland is NOT EPA-authorized for RRP, so EPA administers it here directly;
  • that same work in a pre-1978 RENTAL disturbing ≥6 sq ft additionally requires MDE-approved lead-safe work practices training;
  • ABATEMENT (work designed to permanently eliminate lead hazards) requires an MDE accredited contractor plus an accredited supervisor on site;
  • inspection / risk assessment requires an MDE accredited inspector or risk assessor.
The abatement boundary is enforced on site You cannot classify abatement as RRP to stay on the cheaper credential — MDE enforces the boundary by site inspection.
A lapsed SDAT filing can block the renewal Applications and renewals run through MDE's LRCA database, and an entity must be in SDAT Good Standing to be approved — so a lapsed SDAT annual report can block a lead renewal.
What we have and have not confirmed EXACT CREDENTIAL NAMES AND PER-TYPE CITATIONS ARE NOT YET CONFIRMED AGAINST MDE'S OWN PUBLISHED WORDING — confirm your specific accreditation, its renewal URL and its cycle directly with MDE before relying on this entry for compliance. Cycle, fee band ($125–250), ~60-day approval, the refresher-before-expiry rule and the SDAT coupling are verified; the credential taxonomy above is verified in substance but not in MDE's exact titles.
If you miss the deadline
No statutory grace period after expiration — an expired license is void. Reapplication wait period can be 6+ months for denials.
What you'll typically need
  • Your MDE Lead license / registration number
  • Current general-liability insurance certificate
  • Bond / surety on file
  • The renewal fee (confirm the current amount with the authority)
Where to file
→ Renew at the issuing authority
General guidance — always confirm the exact requirements with the issuing authority before paying or submitting.
