The 2024 Code constitutes a republication of the Montgomery County Code 2014, as updated through July 2024. Chapter 59 of the Montgomery County Code (the “Zoning Ordinance”) underwent a major revision in 2014. The new numbering scheme does not match that used in the prior Code. History notes appearing in parentheses at the end of each section in the Code trace the derivation of each section back to the 1965 County Code and to public local laws adopted by the General Assembly of Maryland. Legislation adopted by the county council is designated as L.M.C. (meaning Laws of Montgomery County) or as Ord. No. or Res. No. Executive orders which assumed the force and effect of local legislation are designated as Ex. Ord. Public local laws adopted by the General Assembly of Maryland are designated by year and chapter of the laws of Maryland (i.e. 1937, ch. 223). By the use of the comparative tables which appear at the back of this Code, the user of the Code may locate any legislation adopted by the county after the legalization of the 2014 Code and any public local law adopted by the General Assembly of Maryland which has been included herein. Legislation and any public local law adopted by the General Assembly of Maryland adopted prior to the 2014 Code may be located in the back of the 2004 Code.

The general index of the Code has been prepared with the greatest of care. Each particular item has been placed under several headings, some of the headings being couched in lay phraseology, others in legal terminology, and still others in language generally used by municipal officials and employees. There are numerous cross references within the index itself which stand as guideposts to direct the user to the particular item in which the user is interested.

A special feature of this Code to which the attention of the user is especially directed is the looseleaf system of binding and supplemental servicing for the Code. With this system, the Code will be kept up-to-date periodically. Upon the final passage of amendatory ordinances, they will be properly edited and the appropriate page or pages affected will be reprinted. These new pages will be distributed to holders of copies of the Code, with instructions for the manner of inserting the new pages and deleting the obsolete pages. Each amendment, when incorporated into this Code through a supplement, may be cited as a part of the 2024 Montgomery County Code, as amended. Since the 2024 Code is based on the 2014 Code as updated through July 2024, the first supplement to the 2024 Code will be the February 2025 Supplement, which will contain all applicable laws and ordinances effective through February 23, 2025. The successful maintenance of keeping this Code up-to-date at all times will depend largely upon the holder of the volume. As revised sheets are received, it will then become the responsibility of the holder to have the amendments inserted according to the attached instructions. It is strongly recommended by the publishers that all amendments be inserted immediately upon receipt to avoid misplacing them and, in addition, that all deleted pages be saved and filed for historical reference purposes.
