International Energy Conservation Code (IECC) Information Page

Purpose: To help building officials, designers, and builders in Maryland evaluate and attain compliance with the International Energy Conservation Code.

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 building codes that are the International Building Code (IBC), the International Residential Code (IRC), and the International Energy Conservation Code (IECC). The State has modified the IBC and the IRC to coincide with other Maryland laws. The International Building Code (IBC), the International Residential Code (IRC), and the International Energy Conservation Code (IECC), with modifications by the State, constitute the Maryland Building Performance Standards (MBPS).

On March 25, 2019, the State of Maryland adopted the 2018 IECC with implementation by local jurisdictions required by March 25, 2020. The Maryland Department of Labor's Division of Labor & Industry, Building Codes Administration Office performs codes administration for the State of Maryland.
