The International Code Council (ICC) is a driving force behind the standards and regulations that govern home remodeling across Maryland. By developing model codes that are adopted and adapted statewide, the ICC ensures that every remodeling project—whether a kitchen upgrade in Baltimore County or a new addition in Montgomery County—meets rigorous requirements for safety, energy efficiency, and quality.
ICC Codes: The Foundation of Maryland’s Building Standards
Maryland law requires every jurisdiction to adopt the same edition of the International Building Code (IBC), International Residential Code (IRC), and International Energy Conservation Code (IECC), all of which are developed by the ICC. These codes, with Maryland-specific modifications, collectively form the Maryland Building Performance Standards (MBPS). This means remodelers and homeowners across the state work from a consistent set of rules, ensuring high standards for construction and renovation.
Statewide Consistency with Local Flexibility
When the ICC releases a new edition of its codes, Maryland’s Department of Labor is required to adopt the new versions within 18 months. Local jurisdictions then have up to 12 months to review, amend (within certain limits), and adopt these codes for local enforcement. While counties and cities can make amendments to address unique local conditions, they cannot weaken the energy conservation or accessibility requirements—these can only be made more stringent. This approach guarantees a consistent baseline for safety and performance, while still allowing for local adaptation.
Remodeling Projects Governed by ICC Codes
For remodelers, ICC codes regulate nearly every aspect of a project, including:
- Structural changes such as removing walls or adding rooms
- Energy efficiency upgrades like insulation, windows, and HVAC systems
- Accessibility improvements including ramps and accessible bathrooms
- Mechanical, electrical, and plumbing work
- Fire safety and egress requirements
Most remodeling activities require permits, and plans must demonstrate compliance with the applicable ICC codes as adopted and amended by the state and local jurisdiction. Inspections during and after construction ensure that all work meets these standards.
Energy Efficiency and Sustainability
The International Energy Conservation Code (IECC), developed by the ICC, sets minimum requirements for energy efficiency in both new construction and remodeling. Maryland is an early adopter of new IECC editions, and the state requires local jurisdictions to enforce these standards without weakening them. This impacts everything from insulation and windows to HVAC upgrades, helping homeowners save on energy costs and reduce their environmental footprint.
Enforcement and Compliance
Local building departments are responsible for enforcing the ICC-based codes through plan reviews, permitting, and inspections. Remodelers must stay current with code updates and local amendments to ensure compliance and avoid costly violations or project delays.
The ICC’s Ongoing Influence
The ICC regularly updates its codes to reflect advances in building science, safety, and sustainability. Maryland’s commitment to timely adoption of these updates means that remodelers and homeowners benefit from the latest best practices in construction and remodeling.
In summary:
The International Code Council shapes remodeling in Maryland by providing the model codes that form the legal and practical foundation for all residential and commercial remodeling work. These codes ensure that projects are safe, energy-efficient, and accessible, while Maryland’s adoption process guarantees statewide consistency with room for local adaptation.
