The climatic and geographic design criteria per 2015 IRC table 301.2(1) for modular buildings must follow the requirements of the individual Maryland local Jurisdictions. The memo asks that the individual counties/cities are contacted for particular requirements for each jurisdiction however, an updated table is provided for reference only. This memo does supersede the three previously issued memos dated November 18, 2011. Please note: The current model performance code applicable to industrialized/modular buildings is COMAR 05.02.01. With the move of the Building Code Administration to DLLR, the COMAR designation is currently projected to be re-designed under COMAR 09.12.50 in March of 2019.
