Maryland, Calvert County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

Calvert County Remodeling and Renovation Permit Requirements

Calvert County's Division of Inspections and Permits is the Authority Having Jurisdiction (AHJ) for building and renovation permits. They are responsible for ensuring compliance with applicable codes through inspections and permit issuance.

Unincorporated Areas

Calvert County issues building permits for properties located in unincorporated areas of the county. If a property is within an incorporated city, that city's building department handles permit applications.

Permit Triggers for Demolition Work

Demolition work during a remodel generally requires a building permit. Specifically, residential demolition requires a building permit. Commercial demolition also requires a commercial building permit. Additional permits, such as a grading permit or a Historic Area Work Permit, may be required depending on the scope of the demolition and the property's location or historical designation.

Permit Requirements for Converting Non-Living Spaces

Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas typically requires several permits to ensure the work meets structural, safety, and energy code requirements.

Basements: Finishing or remodeling a basement into a living area requires a building permit. Electrical, plumbing, and mechanical permits are also necessary if those systems are being installed or modified. Properties served by well and/or septic systems may require review by the Environmental Health Department.
Garages: Converting a garage into a living space will require a building permit. If plumbing or electrical work is involved, separate permits for those trades are also necessary. Garages with living space must meet the same setback requirements as a primary structure.
Attics: While not explicitly detailed as a separate category, converting an attic into a habitable space would generally fall under "interior improvements" or "alterations" and would likely trigger the need for a building permit, along with any necessary electrical or plumbing permits.

For any of these conversions, detailed floor plans showing existing and proposed layouts are typically required as part of the permit application. Licensed professionals (e.g., Master Electrician, Master Plumber) are often required to pull trade-specific permits.

Note: The following state-wide building codes and regulations apply universally to all jurisdictions within Maryland, including Calvert County.

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.
