Maryland Remodeler Legislation, Codes, and Guidelines

Maryland's building codes for remodelers and residential renovations are primarily governed by the Maryland Building Performance Standards (MBPS), which are based on the International Code Council's (ICC) International Building Code (IBC), International Residential Code (IRC), and International Energy Conservation Code (IECC). These codes are adopted and administered by the Maryland Department of Labor, Division of Labor and Industry, Building Codes Administration.

State Statutes and Codes Adopted

Maryland has adopted the 2021 editions of the International Building Code (IBC), International Residential Code (IRC), and International Energy Conservation Code (IECC) as the foundation for its Maryland Building Performance Standards (MBPS). The state also adopts the International Existing Building Code (IEBC) and the Maryland Building Rehabilitation Code (MBRC). Local jurisdictions are required to adopt these state-adopted codes, but they may also implement local amendments to address specific community conditions, with the exception of the IECC and Maryland Accessibility Code, which can only be made more stringent by local jurisdictions.

Primary State Boards or Agencies

The primary state agency responsible for setting and administering building codes in Maryland is the Department of Labor, Division of Labor and Industry, Building Codes Administration. Additionally, the Maryland Home Improvement Commission (MHIC) licenses and regulates home improvement contractors, ensuring they meet specific standards for workmanship and consumer protection.

Classification of Remodels and Demolition Guidelines

Maryland's building codes do not explicitly define "cosmetic remodels" versus "structural alterations" in a single, universally applied definition. However, the distinction is generally made based on the scope of work and its impact on the building's structural integrity, safety, and occupancy.

Cosmetic Remodels: These typically involve superficial changes that do not affect the building's structure, systems, or occupancy. Examples might include painting, replacing flooring, or updating fixtures. While specific code language for "cosmetic damage" exists in other contexts (e.g., vehicle salvage), for building renovations, the focus is on whether the work impacts structural elements or life safety.
Structural Alterations: These involve changes to the building's load-bearing elements, structural frame, walls, or systems. Converting attics or basements to habitable living spaces, removing walls, or altering the building's footprint are considered structural alterations and require permits and adherence to the building codes. The International Existing Building Code (IEBC) and the Maryland Building Rehabilitation Code (MBRC) provide specific guidance for alterations and repairs to existing buildings.
Demolition Guidelines: Demolition permits are generally required for razing or removing a structure, or a significant portion thereof. The specific requirements for demolition permits vary by local jurisdiction. Typically, demolition plans must be submitted separately from construction plans and may require an asbestos survey, a pest control statement (rat eradication), and adherence to recycling requirements. If less than 50 percent of a building is being razed, an Alteration Permit may be required instead of a Razing Permit.
