The Department of Housing and Community Development is the statewide adopting authority. Local jurisdictions can amend the state codes to suit local conditions with the exception of the 2015 IECC and the MD Accessibility Code. Both codes can be made more stringent. Local jurisdictions can amend but must adopt the new editions although no penalties occur should a jurisdiction fail to adopt in a timely manner. Maryland’s law related to building codes is called the Maryland Building Performance Standards (MBPS). It requires each jurisdiction in Maryland to use the same edition of the same I-codes.
State of Maryland adoption of 2018 edition of I-codes and other codes, under Maryland Building Performance Standards and Model Performance Code, has become final in the Maryland Register, Volume 46, Issue 6, March 15, 2019 with an effective date of March 25, 2019.
Please review the information found here for code adoption:

No apparent amendments.
Maryland adopts the triennial edition of the I-codes 18 months after the first printing of the code. June/July adoption date is typical. The 2021 codes are in the process of review and should be adopted mid-year 2022. Howard County has adopted the 2021 in advance of statewide adoption.
