Maryland Contractor Insurance & Bonding Requirements: A Complete Guide for Small Contractors
Maryland requires all home improvement contractors to comply with strict insurance and bonding mandates enforced by the Department of Labor, Licensing and Regulation (DLLR) and the Maryland Home Improvement Commission (MHIC). Failure to maintain current coverage or proper bonds can result in license suspension, fines, or inability to bid on projects. This guide details exactly what small contractors must carry — from minimum liability limits to bond types — to stay legally compliant and competitive in the MD market.
MHIC License Bond Requirements
All contractors performing home improvement work in Maryland must obtain an MHIC license and post a $20,000 surety bond with the Maryland Home Improvement Commission. This bond is not insurance; it protects consumers against fraud, misrepresentation, or failure to complete contracted work. The bond must be issued by a surety company licensed in Maryland and remain continuously active for as long as the MHIC license is valid. Contractors renewing their license annually must submit proof of bond renewal before expiration. Unlike performance bonds, the MHIC license bond does not cover construction defects or delays — only statutory violations under Title 8 of the Business Regulation Article. Sole proprietors, LLCs, and corporations are all subject to this requirement, regardless of business size or annual revenue. Importantly, the $20,000 amount is fixed and does not scale with project value or payroll. Contractors operating without a valid MHIC bond face immediate license revocation and may be barred from reapplying for up to two years. The bond must name the State of Maryland as obligee and include the contractor’s MHIC license number on the instrument.
General Liability Insurance Minimums by Project Size
Maryland does not mandate a statewide minimum general liability limit, but MHIC strongly recommends — and many clients require — specific coverage thresholds based on project scope. For residential projects under $50,000, $300,000 per occurrence/$600,000 aggregate is considered standard. Projects between $50,000–$250,000 typically require $500,000/$1 million, while contracts exceeding $250,000 often demand $1 million/$2 million. These thresholds align with industry best practices and public procurement standards used by Maryland counties like Montgomery and Prince George’s. Crucially, MHIC requires contractors to list their general liability policy number and insurer on their license application and update it within 30 days of any change. Policies must include completed operations coverage and be written by insurers authorized to do business in Maryland. Exclusions for mold, lead abatement, or residential construction must be reviewed carefully — many standard policies exclude these unless specifically endorsed. Contractors should also verify that their policy covers subcontractor negligence under vicarious liability clauses, as MHIC holds licensees accountable for their subs’ actions.
Workers’ Compensation & Additional Insured Endorsements
Under Maryland law (Labor & Employment Article §9-202), any contractor with one or more employees — including part-time, seasonal, or family members — must carry workers’ compensation insurance through the Maryland Workers’ Compensation Commission (MWCC). Sole proprietors with no employees are exempt but lose personal injury protection if injured on the job. Certificates of insurance must be filed with MWCC and made available upon MHIC inspection. Additionally, most general contractors and property managers in Maryland require subcontractors to name them as ‘additional insured’ on general liability policies — specifically via CG 20 10 or CG 20 37 endorsements. These endorsements extend liability coverage to the upstream party for claims arising out of the subcontractor’s negligent acts. Maryland courts uphold such endorsements only when the underlying policy includes ongoing operations coverage and the endorsement is attached prior to work commencement. Failure to provide valid certificates with correct endorsements can result in withheld payments or contract termination. Contractors should audit their policies annually to ensure endorsements remain active and match contractual obligations — especially for multi-year commercial maintenance agreements common in Baltimore and Annapolis.
License Bond vs. Performance Bond in Maryland
In Maryland, the MHIC license bond and performance bonds serve fundamentally different legal purposes and are governed by separate statutes. The $20,000 MHIC license bond is a statutory requirement tied directly to licensure and administered by the Maryland Home Improvement Commission under COMAR 09.08.01. It protects consumers from licensee misconduct, not project failure. In contrast, performance bonds — typically required for public works projects over $100,000 under Maryland’s Little Miller Act (State Finance & Procurement §17-101 et seq.) — guarantee completion of a specific contract. These bonds are procured separately, often at 100% of the contract value, and involve three parties: contractor (principal), owner (obligee), and surety. Private clients may also request performance bonds, especially for renovations exceeding $150,000. Unlike the MHIC bond, performance bonds are project-specific, expire upon job completion, and require financial underwriting based on contractor net worth and backlog. Maryland contractors frequently confuse the two — leading to gaps in protection. Note: MHIC does not accept performance bonds in lieu of the license bond, nor does a license bond satisfy public procurement bonding requirements. Both may be needed simultaneously depending on project type and client.

Do I need workers’ comp if I’m the only employee and use 1099 subcontractors?
Yes — if you have *any* W-2 employees, even one part-time worker, Maryland law requires workers’ compensation insurance. Independent contractors (1099) do not count toward the employee threshold, but misclassifying workers can trigger penalties from the MWCC and DLLR. You remain liable for injuries to misclassified subs.
Can I use my existing business owner’s policy (BOP) instead of standalone general liability for MHIC?
Only if your BOP explicitly includes commercial general liability with no exclusions for residential construction, completed operations, or personal injury — and lists your MHIC license number. Most BOPs lack the required endorsements and limits for home improvement work in Maryland.
What happens if my MHIC bond lapses during a project?
Your MHIC license becomes immediately invalid, exposing you to cease-and-desist orders, consumer complaints, and potential civil liability. Clients may terminate contracts, and you cannot legally solicit new work until the bond is reinstated and approved by MHIC — which may require a new application and background check.
