Maryland MHIC Insurance Requirement: $500,000
Effective June 1, 2024, Maryland home improvement contractors must maintain general liability insurance of at least $500,000. MHIC licensees also pay into the Home Improvement Guaranty Fund, which can reimburse homeowners for certain losses but does not protect the contractor.
Other Maryland Insurance Requirements
- Master plumbers: Plumbing work must be covered by liability insurance, including completed operations, of at least $300,000 bodily injury and $100,000 property damage.
- HVACR contractors: State HVACR licensees who contract for work must carry liability insurance.
- Electrical contractors: Many counties, such as Prince George’s County, set their own liability minimums for electrical licenses.
Maryland Workers’ Compensation for Construction Businesses
Maryland generally requires employers with one or more employees to carry workers’ compensation. Contractors should verify subcontractor coverage, since uninsured subcontractors’ workers can become the hiring contractor’s responsibility.

Residential vs. Commercial Contractor Insurance in Maryland
A contractor remodeling homes in Maryland faces different risks than one building commercial space. Residential work, such as rowhome renovations in Baltimore and remodeling across Montgomery and Howard counties, tends to produce claims for damage to finished interiors, water leaks after a job, and accidents involving service vehicles. Homeowners and lenders increasingly ask to see proof of insurance, and residential exclusions on some policies deserve a close look.
Commercial work, including government, healthcare, and commercial projects in the Baltimore-Washington corridor, typically comes with detailed insurance requirements. Expect requests for $1 million per occurrence and $2 million aggregate, additional insured and completed-operations endorsements, waivers of subrogation, and umbrella or excess limits. Contract language controls what is required, so contractors should review it before signing rather than after a claim.
In Maryland, home improvement contractors need an MHIC license, new home builders must register with the state, and commercial contractors are licensed by county. Confirming license status and insurance requirements before bidding helps avoid delays on both residential and commercial projects.
Common Coverage Gaps for Maryland Contractors
- Uninsured subcontractors: Maryland generally requires workers’ compensation for employers with one or more employees. Hiring subcontractors without current certificates can lead to audit charges or claims against your own policy.
- Personal vehicles used for business: Personal auto policies may not respond when a truck or van is used mainly for work or carries tools and materials between jobsites.
- Tools and equipment: General liability does not cover your own tools. Theft from trucks, trailers, and jobsites is one of the most common uninsured losses for contractors.
- Limits below contract requirements: State or local minimums are often lower than what owners and general contractors require, which can cost you a project or create a breach of contract.
- Weather-related claims: Nor’easters, coastal flooding, and severe storms can lead to water intrusion, storm damage, and incomplete-work claims. Completed-operations and builder’s risk terms should be reviewed before storm season.
- State-specific gap: MHIC licensees must carry at least $500,000 in general liability, so policies with lower limits can put a license at risk.

No. The fund can reimburse homeowners for certain losses but does not protect the contractor against liability claims.

State + Trade + Insurance Product Questions
16. How much does HVAC contractor general liability insurance cost in Maryland?
Premiums depend on your residential and commercial service mix, revenue, employees, claims history, and selected limits. Maryland HVAC contractors generally work under a Maryland HVACR contractor license, and commercial contracts often require higher limits than service work. A quote based on your actual operations gives the most accurate number.
17. Do plumbing contractors need commercial auto insurance in Maryland?
Plumbing businesses that drive vans or trucks to jobs in Baltimore and other Maryland communities should carry commercial auto insurance. Personal auto policies may exclude or limit vehicles used mainly for business or for carrying tools and materials.
18. Does an electrical contractor in Maryland need excess or umbrella liability insurance?
It is not always required by law, but commercial work such as government, healthcare, and commercial projects in the Baltimore-Washington corridor often requires limits above a primary general liability policy. Excess or umbrella coverage can help electrical contractors meet those contract requirements.
19. Do roofing contractors need tools and equipment insurance in Maryland?
It is not legally required, but it is common. Ladders, nail guns, and other equipment are frequently stolen or damaged, and general liability does not cover a contractor’s own tools. With nor’easters, coastal flooding, and severe storms driving storm work, roofing equipment often moves between many jobsites.
20. What type of bond does a general contractor need in Maryland?
Some counties require license or permit bonds, and Maryland public works projects require performance and payment bonds. Bonds guarantee obligations to the party requiring them and do not replace general liability or workers’ compensation insurance.
21. Does a general contractor’s workers’ compensation cover subcontractors in Maryland?
Maryland generally requires workers’ compensation for employers with one or more employees. A general contractor’s policy may be charged for uninsured subcontractors’ workers at audit, so collecting current certificates from every subcontractor helps control premium and claim exposure.
22. Do painters and flooring contractors need workers’ compensation in Maryland?
Maryland generally requires coverage for employers with one or more employees. Even when coverage is not legally required, many general contractors and property managers require artisan subcontractors to carry it before they can start work.
