The Maryland lead certificate cycle, run for you.
Maryland’s Reduction of Lead Risk in Housing law is the reason this page exists. It covers every rental unit in the state built before 1978, which in Montgomery County means roughly 67,650 units, and it makes a current lead inspection certificate a condition of renting the unit at each change of occupancy. Most landlords meet the law for the first time mid-vacancy, with a lease signed and a move-in date bearing down. This page is the version we wish every owner had read a month earlier.
The cycle, in order
- Register the unit with MDE. Once per unit, renewed annually for a small fee. Unregistered covered units are out of compliance before anything else happens.
- Inspect at every change of occupancy. An MDE-accredited inspector checks the unit against the risk reduction standard, including dust wipe samples processed by a lab.
- Correct what fails, with accredited workers. Deteriorated paint and failed surfaces get treated: window treatments, trim stabilization, enclosure, or component replacement. Maryland requires accredited contractors for this work in covered units; handyman scraping is not a lawful shortcut.
- Pass clearance. Fresh dust samples after the work, verified by the lab, below the state standards.
- Hold the certificate. The certificate is your proof of compliance and your qualified defense under the statute. It belongs in the lease file, and a copy goes to the tenant with the required lead disclosure documents.
Where landlords lose money on this
Two places. The first is timing: booking the inspection after move-out instead of at notice, which puts the whole correction-and-clearance cycle inside the vacancy instead of alongside the outgoing tenancy. The second is over-scoping: paying for whole-house work when the standard requires treating specific failed components. Testing first and quoting per component, against the ranges on our cost page, is how both leaks get closed.
Rockville’s extra layer
The City of Rockville runs its own rental licensing program on top of the state law, and voucher units add federal HQS checks that flag deteriorated paint independently. A unit kept to the Maryland standard passes through all of it; the paperwork just needs to be kept straight, which is part of what we do. Area-specific failure patterns are covered on each service-area page, from Takoma Park’s Victorians to Wheaton’s ramblers.
Landlord questions, answered straight
Which of my rental units does the Maryland lead law cover?
Every residential rental unit built before 1978, anywhere in Maryland. Age of the tenant does not matter, condition does not matter, and single-family houses, basement apartments, and units in large complexes all count individually. If it was built before 1978 and someone pays rent to live in it, it is covered.
What is the difference between Full and Modified Risk Reduction?
Both are certificate standards for a unit at turnover. The Full standard is the more thorough treatment of the unit; the Modified standard, available in defined situations, focuses on passing the dust test and correcting specific conditions. Which one applies to your unit depends on its history under the statute; we sort that out per unit and price to the standard that actually applies.
What does the whole cycle cost per turnover?
If the unit passes inspection, you pay for the inspection alone, commonly a few hundred dollars. Units needing correction usually land between $2,500 and $6,000 all-in for component-level work plus clearance testing. First-time certifications on older stock can run more; repeat turnovers on a unit already brought to standard usually cost less. Our cost page publishes every range.
What happens if I skip it and rent the unit anyway?
The exposure stacks: MDE penalties, loss of rent remedies for the tenant, and, most seriously, near-strict liability if a child in the unit tests with an elevated blood lead level without a valid certificate on file. The certificate is also your qualified defense under the statute. It is cheap insurance against an uncapped downside.
I just bought an occupied pre-1978 rental. What do I do first?
Check the MDE registration and transfer it into your ownership, then locate the current certificate if one exists. Your inspection obligation triggers at the next change of occupancy, but deteriorated paint obligations apply continuously. Fifteen minutes of paperwork now avoids scrambling at move-out.
Can you handle a whole portfolio on a schedule?
Yes, and it is the cheapest way to run this. Rolling inspections timed to lease expirations, standardized window and trim treatments, batched clearance testing, and one point of contact for the paperwork. Per-unit costs drop meaningfully versus reacting to each turnover alone.
Turnover coming up?
Book the inspection at notice, not at move-out. We schedule the whole cycle.
