Installing or updating a commercial sign in Maryland involves more than good design—it requires compliance with state and local signage laws. Following the correct regulations helps businesses avoid fines, delayed approvals, or costly removals.
This guide breaks down everything Maryland business owners, contractors, and property managers need to know—especially those working in Baltimore City and Baltimore County.
1. Maryland’s General Commercial Signage Regulations
Maryland does not have one statewide signage code. Instead, each county and municipality sets its own rules. However, most jurisdictions follow similar standards around size, placement, illumination, and permitting.
What Counts as a “Commercial Sign”?
A commercial sign includes:
-
Wall signs
-
Monument signs
-
Pylon or pole signs
-
Awning signs
-
Window lettering
-
Digital or LED message boards
-
Building-mounted illuminated signs

Do You Need a Sign Permit in Maryland?
In most Maryland counties and cities, YES—a sign permit is required for:
-
Permanent exterior signs
-
Signs with electrical components
-
Digital or illuminated displays
-
Structural modifications
-
Temporary banners above a certain size
General Standards (Common Across MD Jurisdictions)
Most Maryland municipalities regulate:
-
Maximum sign area based on zoning
-
Maximum height for freestanding signs
-
Setbacks from sidewalks, roads, and property lines
-
Lighting and brightness limits
-
Material safety and structural integrity standards
Source: Maryland local signage standards are established at the municipal level. Counties follow zoning-based regulations modeled after the Maryland Department of Planning’s municipal zoning guidance, which includes specific rules for size, siting, and illumination.
2. Baltimore City & Baltimore County: What Businesses Must Know
Baltimore City Signage Rules
Baltimore City requires businesses to obtain a Sign Permit issued through the Department of Housing & Community Development.
Key rules include:
-
Compliance with the Baltimore City Zoning Code (Title 17)
-
Additional restrictions in CHAP (historic) districts
-
Regulations on digital illumination and LED brightness
-
Oversight from the city’s Zoning Administrator for special sign types
Historic districts with additional signage rules include:
Fells Point • Mount Vernon • Federal Hill • Bolton Hill • Charles Village
Quoted Source (Paraphrased):
According to the Baltimore City Zoning Code, signs in historic districts must “complement the architectural character of the district” and require review by the Commission for Historical and Architectural Preservation (CHAP).

Baltimore County Signage Rules
Baltimore County regulates signage through the Baltimore County Zoning Regulations (BCZR).
Important highlights:
-
Sign size is tied to the zoning district (e.g., BL, BM, BR zones)
-
Roof signs are restricted in many zones
-
Electronic message centers must auto-dim at night
-
Additional restrictions apply near residential boundaries
Quoted Source (Paraphrased):
The BCZR Section 450 outlines commercial sign requirements, including limits on “maximum sign area,” “total allowable sign height,” and “illumination standards for electronic signs” in business districts.

3. Common Signage Mistakes Maryland Businesses Should Avoid
Avoid these frequent violations:
1. Installing a Sign Without a Permit
This is the #1 reason Baltimore businesses receive violation notices.
2. Oversized Signage
Each zoning district sets a maximum square footage.
3. Incorrect Setbacks
Signs too close to roads or sidewalks can violate sightline rules.
4. Lighting Violations
Many Maryland counties restrict brightness, color temperature, and hours of illumination.
5. Using Non-Approved Materials (Especially in Historic Districts)
CHAP requires specific materials and design compatibility.
6. Not Anchoring or Mounting to Code
Unsafe installations fail inspection and must be corrected.
