Lead Registration

Mission Statement

The Maryland Department of the Environment's Lead Rental Registry mission is to protect families and prevent childhood poisoning from the exposure of lead by ensuring Property Owners register affected properties in compliance with the Maryland State Lead Laws.​


Who Needs to Register?

  • Residential rental properties built before 1978 are required to be registered and then renewed annually with Maryland Department of the Environment.
  • Residential rental properties built after 1977 and properties that have a passing Lead Free inspection certificate are exempt.
  • On or after January 1, 2015, all properties built prior to 1978 must have a new lead inspection certificate at each change of occupancy.

How Do I Renew My Registration?

There are two ways to renew properties in the lead rental registry: This can be done either online or via a paper form.

Renew Online

Paper Form

  • MDE strongly encourages owners to renew online.
  •  As of the 2022 renewal cycle, MDE is mailing a reminder postcard but not mailing printed renewal forms automatically to all owners.
  • If you wish to receive a printed renewal form instead of renewing online, please contact the Lead Rental Registry Section by email at mde.leadreg@maryland.gov. In the subject line of the email, type “Paper Renewal”, in the body type the 7 digit tracking number and the address to be mailed to. You may also call the Lead Rental Registration Hotline at 1-800-776-2706 (in-state) or (410) 537-4199 to request a form.​

  • If you are registering online between October 1st and December 31st you may immediately Renew that property(ies) after completing the initial Registration for it.
  • No matter how late in a calendar year you register a property(ies),  State law requires you to renew that property(ies) for the following year on or before December 31st of that same calendar year​.
