Design and construction modular buildings installed in Maryland should comply with Model Performance Code (COMAR 09.12.50), which include:
2018 edition of IBC, IRC, IECC, IPC & IMC
2017 edition of NEC
The above codes became effective on March 25, 2019. There is a provision which allows a six months “grace period”, under which manufacturers shall start construction of all modular buildings designed to 2015 I-Codes before six months after State’s adoption of new codes.
The deadline for beginning construction of 2015 I-code buildings is 09/25/2019. Starting 06/25/2019, the DLLR office will begin providing a reminder note for all plans submitted for approval if they are designed to 2015 I-Codes.
Please note: after 09/01/2019, no plans will be approved if they are designed to 2015 I-Codes.
