In 1981, Maryland passed the Energy Conservation Building Standards Act
, which established the Maryland Building Performance Standards (MBPS - COMAR 05.02.07), which apply to all new and renovated residential and commercial buildings, and the Maryland Model Performance Code (MPC), which covers state-owned construction and industrialized/modular construction. The Act established a limited role for the Maryland Department of Housing and Community Development (DHCD). The Act also grants them rulemaking authority to amend the MBPS through publications in the Maryland Register and subsequent hearings on administrative actions.
On September 20, 2004, the 2004 MBPS -- based on the 2003 IBC (including Chapter 13- Energy Efficiency) -- became effective.
The next code iteration, the 2007 MBPS
, became effective July 1, 2007. The state adopted (with modifications), the 2006 editions of the International Building Code (IBC), the International Residential Code (IRC), and the International Energy Conservation Code (IECC).
Effective January 1, 2010, the 2010 MBPS
incorporated by reference the 2009 editions of the International Building Code (IBC), the International Residential Code (IRC), and the International Energy Conservation Code (IECC) with modifications by the state. Each local jurisdiction in Maryland may modify these codes to suit local conditions with exception to the 2009 IECC and the energy efficiency chapter (Chapter 13) of the 2009 IBC, which can be made more stringent but not less by the local jurisdictions. The energy efficiency chapter (Chapter 11) of the 2009 IRC has been deleted and replaced with a reference to the 2009 IECC.
Effective January 1, 2012, the 2012 MBPS
reference the 2012 ICC Codes, including the 2012 IECC, for all new and renovated residential and commercial buildings. This update also applies to the 2012 MPC
, which covers state-owned construction and industrialized/modular construction.
Effective January 1, 2015, the 2015 MBPS reference the 2015 International Building code, 2015 International Residential Code for One- and Two-Family Dwellings, and 2015 International Energy Conservation Code as modified by the Department. The updated editions of International Mechanical Code and International Plumbing Code are also included.
