If you have a permit with a printed expiration date of 3/1/20 or after you may continue to use it until 30 days after the Covid-19 State of Emergency is lifted in the State of Maryland.
If you have no permit because you moved to an RPP area or bought a new car or have new license plates, you can apply for a permit online and the Parking Authority will mail you a permit. For most, you will not need to come to their office, even if you need a new permit.
Please open this link for important information about what you, as a resident in an RPP area, need to do (which may likely be nothing!) to avoid getting a ticket.
