General Liability Insurance in Maryland

Maryland landlords routinely require general liability insurance before any commercial space changes hands. Baltimore's commercial corridors, Montgomery County office parks and Prince George's County retail centers all share this expectation: a certificate of insurance on file before a tenant moves in. The requirement comes from the lease agreement, not state law, and most landlords set a minimum of $1 million per occurrence.

What you'll need:

• COI naming the landlord or property manager as certificate holder
• Limits of at least $1 million per occurrence / $2 million aggregate
• Additional insured status is commonly required

Maryland's mix of federal contractors, health care systems and professional services firms means clients bring demanding insurance expectations to service agreements. Businesses working in these environments will almost always need a COI before a contract is signed and sometimes before a bid is even considered.

Common examples:

• Janitorial and facilities cleaning services
• Building maintenance and property services
• On-site consulting and professional services
• Event vendors and trade show contractors

What you'll need:

• COI submitted ahead of the work starting
• Additional insured endorsement naming the client
• Coverage limits that satisfy the specific language written into the contract

Maryland ties contractor licensing to insurance more directly than most states. The Maryland Home Improvement Commission requires all licensed home improvement contractors to carry at least $500,000 in general liability coverage. This requirement took effect June 1, 2024, and applies at both initial licensing and renewal. The MHIC must be notified within 30 days of any policy lapse or cancellation.

Commercial construction licensing runs through each county's Clerk of the Circuit Court rather than a central state board, so insurance thresholds vary across Maryland's 23 counties. Public contracts and larger commercial projects consistently push limits to $1 million per occurrence or higher, with the project owner or agency named as an additional insured.

Common situations:

• MHIC licensing requires proof of coverage at application and each renewal
• County-level construction licenses require COIs as part of the permitting or registration process
• General contractors require subcontractors to carry their own coverage independently

What you'll need:

• COI meeting MHIC requirements with a minimum of $500,000 for home improvement work
• For commercial projects, $1 million per occurrence and $2 million aggregate is the standard expectation
• Additional insured, waiver of subrogation, and primary and noncontributory endorsements on commercial project contracts

Vendors working in Maryland shopping centers, managed commercial properties, or health care and institutional facilities must meet the insurance requirements those organizations set independently. Maryland's concentration of large hospital systems, federal facilities and university campuses pushes vendor insurance thresholds well above standard commercial minimums.

Common examples:

• Service providers and vendors working in retail or commercial developments
• Contractors on recurring service agreements with managed facilities or institutional campuses
• Businesses seeking a spot on approved vendor rosters for property management or facilities groups

What you'll need:

• COI submitted to the vendor compliance administrator or through the designated portal
• Policy terms that meet the vendor or facility agreement's requirements

Maryland government contracts require general liability coverage ranging from $1 million to $5 million, depending on the scope and complexity of the work. Baltimore County and other local jurisdictions require contractors to name the relevant government entity as an additional insured on all liability policies, with 30 days' notice required before any cancellation. 

State agency contracts and public procurement agreements carry their own insurance provisions. Contractors bidding on publicly funded work should review each contracting authority's requirements individually, as they vary across the state.

What you'll need:

• Policy documentation confirming coverage limits meet what the bid, permit or contract specifies
• Endorsements naming the applicable state agency or local government entity as required

Recommended GL coverage:

• Each occurrence: $2 million
• General aggregate: $4 million
• Products-completed ops aggregate: $4 million
• Medical payments: $10,000
• Damage to rented premises: $300,000

Why: The Johns Hopkins institutions alone account for nearly 94,000 jobs and $15 billion in economic output in Maryland, and the broader health care and life sciences ecosystem spanning Baltimore, Rockville and the I-270 corridor makes this the state's largest private employment sector. Clinical and pharmaceutical operations carry considerable products-completed operations exposure, and the contractual insurance minimums major hospital systems impose on vendors and service partners routinely exceed standard market limits.

Recommended GL coverage:

• Each occurrence: $2 million
• General aggregate: $4 million
• Products-completed ops aggregate: $2 million
• Medical payments: $5,000
• Damage to rented premises: $100,000

Why: The federal government employs over 140,000 people directly in Maryland, with state and local government adding nearly 340,000 more, and the surrounding network of defense and intelligence contractors supporting agencies like the NSA and NIH represents one of the largest government contracting ecosystems in the country. Maryland government contracts usually require minimum GL coverage limits ranging from $1 million to $5 million depending on contract complexity and risk level, making elevated limits a practical prerequisite for any business operating in this space.

Recommended GL coverage:

• Each occurrence: $1 million
• General aggregate: $2 million
• Products-completed ops aggregate: $1 million
• Medical payments: $5,000
• Damage to rented premises: $100,000

Why: Maryland ranks second in the Milken Institute's State Technology and Science Index and leads the nation in concentration of IT employment across the Baltimore-Washington corridor. Professional and technical services firms operating in this environment face client-facing premises liability at office locations alongside contractual GL requirements embedded in government and commercial service agreements. While physical exposure is lower than in high-risk trades, standard limits remain a baseline condition for securing contracts and commercial leases across the state.

Recommended GL coverage:

• Each occurrence: $1 million
• General aggregate: $2 million
• Products-completed ops aggregate: $2 million
• Medical payments: $5,000
• Damage to rented premises: $100,000

Why: Maryland requires general liability coverage by law for any contractor performing home improvements, and the type of work performed determines the coverage level required for licensing. Active residential and commercial development across the Baltimore-Washington corridor, combined with heavy infrastructure investment, keeps demand for contractor coverage high. Most commercial clients and project owners expect $1 million per occurrence as a contractual minimum, and job-site property damage and bodily injury claims are among the most frequently reported GL exposures across the state.

Recommended GL coverage:

• Each occurrence: $1 million
• General aggregate: $2 million
• Products-completed ops aggregate: $2 million
• Medical payments: $5,000
• Damage to rented premises: $300,000

Why: Retail trade ranks among Maryland's leading industries by employment. Large concentrations of retailers operate in the Baltimore metro, the DC suburbs of Montgomery and Prince George's counties, and Ocean City's seasonal coastal market. Slip-and-fall and premises liability claims are the primary GL drivers for retailers statewide, and Maryland's severe thunderstorms, high winds and flooding in 2024 created additional storm-related liability exposure for businesses with public-facing premises. Most commercial landlords require a certificate of insurance before executing any retail lease agreement.
