Maryland

Updated 3/15/2025

Overview

Maryland follows the Maryland Building Performance Standards (MBPS), which requires all jurisdictions to adopt the same edition of the International Codes (I-Codes). The Department of Housing and Community Development serves as the statewide adopting authority. While local jurisdictions must adopt the latest editions of these codes, they can make amendments to address local conditions. However, amendments to the 2018 International Energy Conservation Code (IECC) and the Maryland Accessibility Code are restricted to only making them more stringent. There are no penalties if a jurisdiction does not adopt the latest edition in a timely manner.

Hybrid Adoption

A hybrid adoption system means codes can vary at state and local level. Many times the state establishes a base code for building regulations and local jurisdictions then have the authority to amend or adopt more stringent requirements. This allows flexibility for cities and counties to tailor codes to their specific needs while maintaining a foundational standard set at the state level.
