Bethesda, Maryland Remodeler Local Permit Ordinances and Codes
Bethesda, Maryland Municipal Permit Ordinances for Remodelers and Home Renovations
In Bethesda, Maryland, home renovation and remodeling projects are regulated by Montgomery County. The primary authority for issuing permits and enforcing building codes is the Montgomery County Department of Permitting Services (DPS).
Permit Triggers for Demolition vs. Building Permits
The distinction between requiring a demolition permit versus a standard residential building or alteration permit is based on the extent of the work:
- A demolition permit is required when a building is being razed or removed in its entirety.
- More specifically, a demolition permit is mandated if two-thirds (67%) of the first-story exterior walls of a single-family dwelling, duplex, or townhouse are removed, or if less than one-third of the existing first-floor exterior walls enclosing habitable space (above the basement or foundation) are left in place.
- An alteration permit is generally required for reconstruction or renovation to an existing structure that goes beyond simple repairs. This includes partial demolition that does not meet the criteria for a full demolition permit, as well as significant changes to the home's structure, layout, or systems.
- Cosmetic changes that do not affect the structure or utilities, such as painting, replacing countertops, installing new flooring, or replacing fixtures without altering plumbing lines, typically do not require a permit.
Space Alterations: Converting Non-Living Spaces
Converting non-living spaces like basements or garages into habitable areas requires specific attention to zoning and building codes:
- Converting an unfinished space into a habitable area, such as an Accessory Dwelling Unit (ADU), requires a building permit.
- These conversions must meet current building code requirements for features like ceiling heights, windows, stairs, and exits.
- All applicable zoning ordinance requirements must also be met.
- Specific regulations exist for Accessory Dwelling Units (ADUs), which can include basement apartments or apartments over garages. These units have size, height, and setback requirements based on zoning.
- Plumbing permits from the Washington Suburban Sanitary Commission (WSSC) are typically required for any new bathroom, bar sink, drain relocation, or gas line work within these converted spaces.
Fee Nuances and Inspection Stages
- Permit fees in Montgomery County are generally based on the project's scope and the Gross Building Area (GBA).
- Typical permit costs for kitchen remodels can range from $300 to $1,200, with larger or more complex remodels incurring higher fees.
- Additional fees may be assessed for permit revisions or re-inspections if work is not ready or if there are more than six deficiencies.
- Inspections usually occur in stages. For basement finishes, this can include rough-in inspections for electrical, mechanical, and building trades before insulation, followed by an insulation inspection before drywall.
- A "combo close-in" inspection can group electrical, mechanical, and building rough-in inspections.
- WSSC plumbing final inspections must be passed before other final trade inspections.
- Approved plans must be on the job site for each inspection.
- Re-inspection fees are charged if an inspection is disapproved or if the inspector cannot access the work.

Because Bethesda is located within Montgomery County, the following broader county regulations may also apply to your project:
Maryland, Montgomery County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Montgomery County, Maryland Remodeling and Renovation Permit Requirements
The Montgomery County Department of Permitting Services (MoDPS) is the Authority Having Jurisdiction (AHJ) for building and safety in Montgomery County, Maryland. This department oversees all aspects of construction, renovation, and demolition permits to ensure compliance with building codes and safety standards.
Unincorporated Areas
The rules and permit requirements for properties in unincorporated areas of Montgomery County are the same as those within incorporated municipalities, as MoDPS has county-wide jurisdiction.
Demolition Work
Permit requirements for demolition work during a remodel depend on the scope of the demolition. Generally, any demolition that affects the structural integrity of the building, involves the removal of load-bearing walls, or is a complete demolition of a structure will require a permit. It is advisable to consult with MoDPS directly to determine specific triggers for demolition permits based on your project's details.
Converting Non-Living Spaces
Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas is considered a significant alteration and typically requires a building permit. This process involves ensuring that the converted space meets all current building code requirements for egress, ventilation, insulation, electrical, and plumbing. Definitions for these spaces and the specific requirements for their conversion can be found within the Montgomery County Building Code and related regulations.

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.
