Baltimore, Maryland Remodeler Local Permit Ordinances and Codes
Baltimore, Maryland Municipal Permit Ordinances for Remodelers and Home Renovations
In Baltimore, Maryland, the primary authority for building permits and home renovations is the Baltimore City Department of Housing and Community Development (DHCD). For Baltimore County, the Department of Permits, Approvals and Inspections (PAI) is the governing body.
Permit Triggers for Demolition vs. Building Permits
In Baltimore City, a demolition permit is required before any demolition work begins. Generally, a building permit is needed for any project that involves constructing, enlarging, altering, repairing, rehabilitating, demolishing, or moving any structure. This includes significant electrical, gas, mechanical, or plumbing system work, as well as changes to the use of a structure or land, or any grading or excavating. Renovations, modifications, and reconstructions almost always require a permit.
In Baltimore County, a razing (demolition) permit is required for all structures except those under 120 square feet. If less than 50 percent of a building is being razed, an Alteration Permit is needed instead of a Razing Permit. For both City and County, if the project involves structural changes, electrical, plumbing, or mechanical work, a building or alteration permit will likely be required.
Space Alterations: Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces like basements or garages into habitable areas in Baltimore City typically requires multiple permits, including a building permit for structural changes (framing, altering ceiling height, adding windows/doors/bedrooms), an electrical permit, and a plumbing permit if new fixtures are added. A mechanical permit is needed for HVAC system modifications, and a fire protection permit may be required if an existing sprinkler system is altered.
In Baltimore County, a building permit is generally required to convert unfinished basement space into a finished space if structural changes are involved, a new bedroom is added, or if the property is in a flood zone, historic district, or Chesapeake Bay Critical Area. Plumbing, gas fitting, and electrical work require separate trade permits pulled by licensed professionals.
It's important to note that in Maryland, a basement sleeping area requires an egress (Emergency Escape and Rescue Opening), which can be a window or door, meeting specific size and safety code requirements.
Fee Nuances and Inspection Stages
Permit fees in Baltimore City are generally based on the estimated construction value of the project. Additional fees may include plan review and inspection fees.
In Baltimore County, building permit fees vary widely based on the permit type, project size, and value. The county offers an online portal for permit applications and fee payments.
Inspections are a crucial part of the permitting process in both Baltimore City and County. For basement renovations, typical inspections include plumbing groundwork before covering floors, trade inspections (electrical, plumbing, mechanical, fire protection) before building inspections, and insulation inspections before drywall installation. Permits and approved plans must be available at the job site for inspections.

Remodeling and Renovation Permit Requirements for Baltimore City, Maryland
In Baltimore City, Maryland, the Department of Housing and Community Development (DHCD) serves as the Authority Having Jurisdiction for building and safety matters. This department is responsible for enforcing building codes and issuing permits for construction, renovation, and demolition projects.
Baltimore City is a consolidated city-county, meaning there are no unincorporated areas within its limits. Therefore, all properties within Baltimore City are subject to the same permit requirements and regulations enforced by DHCD.
Demolition Work During a Remodel
Demolition work, even as part of a larger remodel, often triggers the need for a permit in Baltimore City. This is especially true if the demolition involves:
- Removing any structural elements.
- Taking down load-bearing walls.
- Demolishing more than a minor portion of the building's interior or exterior.
- Any work that could affect the structural integrity or safety of the building or adjacent properties.
It is always advisable to consult with DHCD to determine if your specific demolition plans require a permit.
Converting Non-Living Spaces to Habitable Areas
Altering or converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas requires specific permits and must comply with current building codes. These projects are generally considered significant renovations because they involve changes to:
- Occupancy classification.
- Structural integrity.
- Egress (exits).
- Ventilation and insulation.
- Plumbing, electrical, and mechanical systems.
A permit is typically required for any work that changes the use of a space, increases the occupancy load, or involves substantial construction. This includes adding bathrooms, bedrooms, or kitchens to these areas. The process will likely involve plan reviews to ensure compliance with zoning, building, fire, and residential codes.

The following statewide building codes and regulations apply universally to all jurisdictions within Maryland:
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.
