People search for a lead inspection and get quoted four different things. A landlord with a turnover needs one specific test, a buyer wants another, and a parent with a sick child needs a third. This page sorts them out using MDE’s own descriptions, then explains what a failure means, how long each certificate lasts, and who has to register. Where a rule is quoted, the MDE page it came from is named.
The four inspection types
| Test | What it measures | When it applies |
|---|---|---|
| Visual inspection | A surface by surface look for chipping, peeling or flaking paint, inside and out. | Part of every rental certificate. On its own it is the first half of a Modified Risk Reduction inspection after a defect notice. |
| Dust wipe sampling | Wipes from floors and sills in each room, analyzed by a qualified laboratory for lead-contaminated dust. | The test the Full Risk Reduction turnover certificate is built on. Also the clearance test after correction work. |
| XRF paint testing | A handheld analyzer reads lead content in the paint itself, component by component, without disturbing it. | The Lead Free and Limited Lead Free surveys, and pre-purchase or pre-renovation testing. |
| Risk assessment | Paint condition and dust, sometimes soil as well, read together to identify hazards and recommend treatments. | Occupied units with a child health concern, elevated blood lead follow-up, and grant or lender programs that ask for one. |
Which one the rental certificate needs
The dust test, with the visual check built in. MDE’s fact sheet Lead Paint Certificates for Rental Housing puts it in one sentence: the Full Risk Reduction standard is met by passing the test for lead-contaminated dust, provided that any chipping, peeling or flaking paint has been removed or repainted on the interior and exterior of the unit. After verifying paint condition, the inspector collects dust samples from each room, a qualified laboratory analyzes them, and the results must fall below specified levels. MDE’s Inspections for Rental Housing page adds that this inspection is generally conducted in a vacant unit prior to occupancy by a new tenant.
A Modified Risk Reduction inspection is the occupied-unit version: a visual inspection plus a dust inspection, triggered by a written notice of defective paint or by a high blood lead level in a child or pregnant woman living there, per the same MDE page. XRF testing is the route to a Lead Free or Limited Lead Free certificate, which is an exemption from the turnover cycle rather than a turnover certificate. The lead certificate pagelays out all four certificate types with MDE’s wording, and our article on inspection versus risk assessment covers the case where someone quotes you the wrong test.
Why the inspector has to be independent
Maryland separates the company that tests from the company that fixes. COMAR 26.16.01.09, Lead Paint Abatement Services Contractor Accreditation Requirements, says a contractor providing inspection or lead paint risk assessor services may not have a financial interest in the contractor conducting an abatement project for which it is providing services, and may not be a related party to the property owner. We arrange correction work with MDE-accredited crews, which is exactly why we do not inspect. What we do is match you with an MDE-accredited lead inspector who covers your county, confirm the property’s age and registration status first, and step back from the result.
What happens if you fail
The report lists the surfaces with deteriorated paint and the dust samples that came back over the state levels. Under COMAR 26.16.02.03 the inspector submits failing documentation to MDE within 30 calendar days, and a passing certificate within 10 calendar days of receiving the lab analysis. Between those two events, the owner corrects the listed items. The MDE Property Owner Compliance Summary requires that all work performed to meet any standard be done by persons or companies trained or accredited by MDE, so a handyman with a scraper is not a lawful fix. Then a fresh set of dust wipes, and if they pass, the certificate. Reading the report, and the order to fix things, is the subject of our failed inspection guide; correction prices are on the cost guide.
How long a certificate lasts
- Full Risk Reduction (turnover) certificate.Covers the unit until the next change in occupancy. MDE’s Lead Registration for Landlords page requires a valid lead inspection certificate at each tenant turnover unless the property is certified lead free.
- Limited Lead Free certificate. MDE says these are only good for two years, and the exterior must pass a re-inspection for chipping, peeling or flaking paint before the certificate expires. Miss the re-inspection and the original certificate is no longer considered valid.
- Lead Free certificate. A unit determined to be free of lead paint is exempted from registration fees and from further risk reduction inspection requirements, per MDE. There is no obligation under the law to abate a unit all the way to Lead Free; it is an option, not a mandate.
Who has to register with MDE
Owners of rental homes built before 1978, statewide, per the MDE page Lead Registration for Landlords. The Compliance Summary sets the initial registration deadline at 30 days after acquiring the property, requires the Notice of Tenants Rights and the Protect Your Family from Lead in Your Home brochure plus a copy of the current certificate to go to tenants, and says compliance is mandatory regardless of renovation history. MDE lists the current per-unit fee and renewal schedule on the landlord page. The two exemptions the summary names are transient lodging such as hotels and motels, and units an accredited inspector has certified Lead Free or Limited Lead Free. The full turnover cycle for Montgomery County owners is on our landlord guide.

Inspection questions, answered straight
Which inspection does the Maryland rental certificate actually need?
A dust inspection. MDE’s page Inspections for Rental Housing says a Full Risk Reduction certification requires a dust inspection, generally conducted in a vacant unit prior to occupancy by a new tenant, with samples from each room falling below specified levels. The inspector first confirms there is no chipping, peeling or flaking paint inside or out. A risk assessment or an XRF survey answers a different question.
Who is allowed to perform it?
Only an MDE-accredited lead paint inspection contractor. The MDE fact sheet Lead Paint Certificates for Rental Housing states that only accredited inspectors are qualified to provide these inspection services, and COMAR 26.16.02.03 has the certificate issued by an accredited lead paint visual inspector or risk assessor. MDE keeps a public list of accredited inspection contractors on its data viewer.
Why does this site match me with an inspector instead of inspecting?
Because Maryland keeps the tester independent of the fixer. COMAR 26.16.01.09 says a contractor providing inspection or risk assessor services may not have a financial interest in the contractor conducting an abatement project it is inspecting, and may not be a related party to the property owner. We arrange correction work with accredited crews, so the inspection has to come from someone else. We connect you with an accredited inspector who covers your county and stay out of the result.
What happens if the unit fails?
The inspector reports the failing surfaces and dust results and, under COMAR 26.16.02.03, submits the failing documentation to MDE within 30 calendar days. You correct the listed items using MDE trained or accredited workers, which the Property Owner Compliance Summary requires for all work performed to meet any standard, then an accredited inspector re-tests the dust. Our failed inspection article walks through the report.
How long does a certificate last?
It depends on the type. The turnover certificate covers the unit until the next change in occupancy: MDE’s Lead Registration for Landlords page requires a valid lead inspection certificate at each tenant turnover. A Limited Lead Free certificate, per MDE, is only good for two years and needs an exterior re-inspection before it lapses. A Lead Free certificate exempts the unit from further risk reduction inspections.
Who has to register with MDE?
Owners of rental homes built before 1978, per MDE’s Lead Registration for Landlords page. The Property Owner Compliance Summary adds that registration is due within 30 days of acquiring the property and that compliance is mandatory regardless of renovation history. MDE publishes the current per-unit fee and renewal schedule on the landlord page. Hotels, motels and similar transient facilities are exempt, as are units certified Lead Free or Limited Lead Free.
