If you own a building in Baltimore County that contains six dwelling units or fewer that you intend to rent, each rental unit must be registered or approved for exemption by Baltimore County before tenants move in.
There are a number of conditions that may qualify your property for exemption. Review the criteria listed on the Exemption Affidavit (PDF) and if any of these conditions apply, complete an application for exemption.
If your property is not qualified for exemption, follow the steps below to register it with Baltimore County.
Step 1: Know the Registration Fees
