Baltimore County Business License: Trader's License, Permits and Local Rules

Starting or operating a business in Baltimore County requires navigating several layers of permits and licensing requirements. Unlike some states with a single business license, Maryland requires different permits depending on your business type and location. This guide covers what you actually need, what it costs, and what local rules apply.

What You Need to Know First

Baltimore County has no single general business license. Most businesses that sell goods need a trader's license, issued by the Clerk of the Circuit Court in Towson. If you grow crops or manufacture goods, you are exempt from the trader's license requirement, but you may still need other permits depending on your specific operation.

Before the Clerk will issue a trader's license, you must:

• Have a Sales and Use Tax License from the Maryland Comptroller (free, obtained through the state's Combined Registration Application at businessexpress.maryland.gov)
• Obtain zoning approval from the county zoning commissioner for first-time licenses
• Not owe personal property tax or have missing filings with the Maryland State Department of Assessments and Taxation (SDAT)

The trader's license year runs May 1 through April 30. This matters: if you file in March, your first license covers only the remainder of that year and expires April 30.

Baltimore County Trader's License: Fee Structure by Stock Value

Baltimore County uses a stock value tier system spelled out in Business Regulation 17-1807(c)(4). Your license fee depends on the value of goods you keep in stock. Here are the 11 tiers:

Stock Value	License Fee
Up to $1,000	$20
$1,001 to $5,000	$40
$5,001 to $10,000	$80
$10,001 to $50,000	$160
$50,001 to $100,000	$375
$100,001 to $200,000	$450
$200,001 to $300,000	$500
$300,001 to $400,000	$775
$400,001 to $500,000	$1,000
$500,001 to $750,000	$1,250
Over $750,000	$1,600

You declare your stock value on the application. The Clerk may request documentation (inventory records, receipts, bank statements) to verify your stated value.

The Zoning Commissioner Approval Step

First-time traders must obtain approval from the Baltimore County zoning commissioner under Business Regulation 17-1805. This is not optional. The zoning approval confirms that your intended business use is permitted in your location under county zoning code. Without it, the Clerk cannot issue the license.

The zoning commissioner reviews whether your use class is allowed in the zone where you plan to operate. For example, a retail shop is allowed in commercial zones but not in residential zones. Some uses require special exceptions or variances, which can add time and cost to the process.

Contact the Baltimore County Department of Permits, Approvals and Inspections for zoning questions: they handle both zoning determination and building permits.

Building Permits and Code Compliance

Before you open your doors, you need a building permit if you are renovating, constructing, or substantially altering the space. Baltimore County requires permits for:

• Structural changes, additions, or alterations
• Electrical work (beyond very minor repairs)
• Plumbing installations or repairs
• HVAC installation or modification
• Fire suppression systems
• Tenant fit-out and interior modifications in commercial spaces

Building permits are issued by the Department of Permits, Approvals and Inspections in Towson. The permit cost varies by project scope and estimated cost of work. Work must pass final inspection before occupancy.

If you are leasing an existing space that is already permitted for your use, you may not need a building permit. Confirm with the department before starting work.

Plumbing and Electrical Licensing in Baltimore County

Maryland's State Board of Plumbing has no jurisdiction in Baltimore County. The county issues its own master plumber and gas fitter licenses. If you are installing plumbing, you must hire a licensed county plumber or pull the permit yourself if you are a licensed plumber.

Electrician licensing is more complicated. The Maryland Electricians Act of 2020 may have changed how local licensing works. Confirm current electrician licensing requirements and fees with the Baltimore County Department of Permits, Approvals and Inspections before hiring or licensing an electrician.

Liquor Licenses and Alcohol Sales

If you plan to sell beer, wine, or liquor, you need a license from the Board of Liquor License Commissioners for Baltimore County. License types and fees vary widely:

• Off-premises licenses (package stores, grocery stores, gas stations) allow you to sell sealed containers
• On-premises licenses (bars, restaurants) allow consumption on-site
• Licenses for beer and wine only cost less than full liquor licenses
• Special licenses exist for breweries, wineries, and distilleries

Liquor license requirements include posting public notice at the location, obtaining neighbor approval in some cases, and sometimes appearing before the Board. The Board meets regularly in Towson. Ask the Board for the current fee for your license type.

Ask the Board for its current timeline from application to approval.

Local Taxes That Apply in Baltimore County

Beyond the Maryland state income tax (2% to 6.5%, depending on income bracket), Baltimore County imposes:

• Local Income Tax: 3.20% for calendar year 2026, withheld from employee paychecks or paid quarterly by self-employed persons
• Business Personal Property Tax: $2.75 per $100 of assessed personal property value (2026-2027 rate from SDAT). Businesses report tangible personal property (equipment, inventory, fixtures) on an annual return to the county assessor.
• Admissions and Amusement Tax: 10% on admission charges and amusement services
• Hotel Rental Tax: 9.5% on room charges in Baltimore County hotels (if applicable to your business)
• Sales Tax: Maryland has a single statewide sales tax of 6% and no local sales taxes, so Baltimore County adds no rate of its own. A Sales and Use Tax License from the Comptroller is required before the Clerk will issue a trader's license.

File annual personal property tax returns with the county assessor and local income tax returns with the Maryland Comptroller.

Baltimore County Zoning: What You Need to Know

Baltimore County has a detailed zoning code that regulates land use, building height, setbacks, parking, and sign sizes. Your first step is to confirm that your business use is allowed in the zone where you want to operate. This is what the zoning commissioner approval covers for first-time traders.

Common issues that require zoning review:

• Home-based businesses in residential zones (most are prohibited or heavily restricted)
• Off-site parking in a different zone than your business
• Signage exceeding the zoning square-footage limit
• Outdoor storage or manufacturing operations
• Change of use in a previously permitted space

The zoning code is available online from the Baltimore County Department of Permits, Approvals and Inspections, or you can call them directly to verify that your planned use is allowed.

Enterprise Zones and Tax Incentives

Baltimore County has three designated enterprise zones where certain businesses may qualify for tax incentives and expedited permitting:

• Chesapeake Enterprise Zone
• Southwest Baltimore County Enterprise Zone
• Woodlawn Enterprise Zone

If your business is located in one of these zones and qualifies under state and county criteria, you may be eligible for an enterprise zone property tax credit. Contact the Baltimore County Department of Commerce to determine your eligibility.

The Application Process: Step by Step

Here is the typical path to getting your trader's license:

1. Get a Sales and Use Tax License. Apply online at businessexpress.maryland.gov. This is free and usually approved within days.
2. Obtain Zoning Approval. Contact the Baltimore County Department of Permits, Approvals and Inspections with your address and planned business use. They will confirm whether your use is allowed in that zone. If approved, they issue a zoning letter.
3. Prepare Your Application. Get the trader's license application from the Clerk of the Circuit Court in Towson. Fill in your business name, address, stock value, and ownership information.
4. Submit to the Clerk. Bring the application, zoning approval letter, and Sales and Use Tax License confirmation to the Clerk's office. Pay the fee based on your stock value tier.
5. Receive Your License. Ask the Clerk how long issuance takes. The license is valid until April 30 of the next year.

Special Situations and Additional Permits

Certain businesses need additional permits beyond the trader's license:

• Food Service: Restaurants, bakeries, and food trucks need health permits from the Baltimore County Department of Health.
• Childcare: Daycare centers and family childcare homes need licenses from the Maryland State Department of Education, Office of Child Care.
• Home-Based Businesses: Most are prohibited in residential zones unless they are specifically allowed by code (e.g., professional offices, but not retail or manufacturing). Even allowed home businesses may need a separate home occupancy permit.
• Signage: Signs in Baltimore County may need a permit, especially if they are over a certain size or height. Internal illuminated signs have different rules than roof-mounted signs.
