What a Certificate of Insurance Does Not Do, and Why DMV Contractors Get Burned

Ask a contractor whether the sub on site is insured and you will usually get a certificate handed over. Ask whether that certificate actually protects the business and you will usually get a pause.

It is worth being precise here, because the document itself is unusually honest about its own limits and almost nobody reads that part. And because the three jurisdictions we work in answer the underlying question in three genuinely different ways.

What the certificate says about itself

The standard form is the ACORD 25, Certificate of Liability Insurance. Its own header states that it is issued as a matter of information only, that it confers no rights upon the certificate holder, and that it does not affirmatively or negatively amend, extend or alter the coverage afforded by the policies listed.

Read plainly, that means a certificate is evidence that a policy existed on the day somebody printed it. It is not a contract, it is not a promise, and it cannot give you anything the policy does not already give you. A policy can be cancelled the week after the certificate is issued and the certificate will look exactly the same.

Certificate holder versus additional insured

These two get used interchangeably and they are not close to the same thing.

A certificate holder is simply the party the certificate was sent to. It usually means you get notice of cancellation. It does not mean you are covered.

An additional insured means you are actually an insured under someone else policy. That status is created by an endorsement to the policy, commonly a CG 20 10 for ongoing operations or a CG 20 37 for completed operations, or by a blanket additional insured provision in the form itself.

Completed operations is the one that gets dropped. A contractor who is an additional insured for ongoing operations only has no protection for a claim that surfaces after the job is finished, which is when most construction defect claims actually surface.

The practical rule, and it applies on every side of the river: collect the endorsement, not just the certificate. If a subcontractor cannot produce the endorsement page, you do not have what your contract says you have.

Three jurisdictions, three different answers

This is where contractors working across the DMV get caught. The same crew, doing the same work, faces different licensing law depending on which side of a line they are standing on.

Maryland

Maryland has no state general contractor license for commercial construction. There is no board, no exam, and no state insurance requirement for commercial work. What exists is a construction license sold by the Clerks of the Circuit Court, which is a revenue registration rather than a test of competence, plus the usual state trade licenses for electricians, plumbers and HVACR.

Residential is a different world. Anyone acting as a home improvement contractor needs a Maryland Home Improvement Commission license, and there is no dollar threshold in the statute. The scope is broad: additions, alterations, remodeling, repair, replacement, and adjacent work like driveways, decks, fences, garages and pools.

The number worth knowing: Maryland raised the MHIC general liability minimum from 50,000 dollars to 500,000 dollars, effective October 1, 2024. If you go looking, the Commission own licensing page still lists the old 50,000 dollar figure, which is why you will see both numbers quoted. The statute is what controls.

Instead of a surety bond, Maryland runs a Guaranty Fund for homeowners. It pays actual loss up to 30,000 dollars per claimant and 250,000 dollars in total for any one contractor, and it excludes attorney fees, consequential damages, court costs, interest and personal injury. The part that matters most: the Fund only responds to the acts of a licensed contractor. Hire an unlicensed one and the homeowner has no Fund, no bond, and quite possibly no general liability policy either.

Locally, Montgomery County adds a New Home Builder Registration for ground up residential work, and it requires proof of at least 500,000 dollars in liability coverage plus workers compensation. That chapter applies in Gaithersburg and Rockville as well as the unincorporated county. Prince George County has a similar registration for new residential construction. Howard, Anne Arundel and Frederick license trades and issue permits but do not license general contractors.

District of Columbia

DC requires a Basic Business License with a contractor endorsement, either General Contractor and Construction Manager or Home Improvement Contractor. The issuing agency is the Department of Licensing and Consumer Protection. It is no longer DCRA, which was reorganized in October 2022, with building permits and certificates of occupancy moving to the Department of Buildings. A surprising number of published guides still say DCRA.

DC is the only one of the three that writes the insurance limit into the license class. General contractor licenses run in five classes tied to the value of a single project, and each class carries its own general liability minimum, from 500,000 dollars per occurrence at the smallest class up to 2.5 million at the unlimited class. The policy must also name the DC Treasurer as an additional insured on a primary and non contributory basis, and the Director gets 30 days notice before cancellation or lapse.

Home improvement contractors in DC post a 25,000 dollar surety bond and file a certificate of liability insurance naming DLCP as certificate holder. Worth knowing what that bond does and does not do: the surety is not responsible for completing the contract. It responds to a homeowner financial loss from a violation the contractor could be prosecuted for. It is a consumer protection device, not a performance guarantee.

Everyone also needs Clean Hands. If you owe the District more than 1,000 dollars in taxes, fines or water charges, or you have not filed a required DC return, the license does not issue.

One practical note for Maryland and Virginia firms working in the city: if your business is not physically located in DC, you do not need a DC certificate of occupancy. You still need the license, the insurance, the bond where it applies, and Clean Hands.

Virginia

Virginia amended its contractor license thresholds in 2025. The current classes are Class A at 150,000 dollars or more per contract or 1,000,000 or more annually, Class B from 30,000 to under 150,000 or 250,000 to under 1,000,000 annually, and Class C above 1,000 and under 30,000 or under 250,000 annually. A good deal of published guidance still quotes the old 120,000 dollar Class A figure.

Here is the part that surprises people. The Virginia Board for Contractors does not require general liability insurance to hold a license. Virginia checks financial responsibility, experience and the required coursework. It does not check your certificate. Which means a properly licensed Virginia contractor can be entirely uninsured and still be licensed.

What your customers require, which is stricter than any of them

Licensing law sets a floor. Contracts set the real requirement, and the gap between the two is where contractors lose money.

Public owners across the region ask for a fairly consistent shape: specified limits, additional insured status on a primary and non contributory basis, a waiver of subrogation, copies of the endorsements as proof, and thirty days notice of cancellation or non renewal. Private general contractors in Bethesda, Silver Spring, downtown DC, Fairfax and Alexandria ask for the same shape with limits that move by job.

Put that next to what the states actually mandate and the mismatch is obvious. A Maryland home improvement contractor carrying the 500,000 dollar MHIC minimum is fully compliant with state law and will still fail the insurance requirements of most commercial general contractors in the region. A Virginia contractor with no general liability at all is licensed and will not get past a prequalification form.

If your policy cannot deliver primary and non contributory wording, a waiver of subrogation, completed operations for additional insureds, and a per project aggregate, you will lose work over it long before any regulator notices.

Public work brings bonds into it

Both Maryland and DC require payment and performance security on public construction, at very different trigger points.

Maryland generally requires it once a contract exceeds the small procurement amount, which is 100,000 dollars for most units and 200,000 dollars for Department of General Services and Department of Transportation construction. Payment security must be at least 50 percent of the total amount payable. Maryland also voids pay if paid and waiver clauses on these contracts as against public policy.

DC starts far lower. Payment and performance bonds are required on contracts exceeding 25,000 dollars for construction, alteration or repair of a District public building or public work. The payment bond runs on a sliding scale: 50 percent of the contract up to a million dollars, 40 percent above that up to five million, then a flat 2.5 million.

If you are used to Maryland thresholds and you pick up a small DC job, that 25,000 dollar line is easy to walk past.

Workers compensation, and why you check the sub

Maryland and DC both require coverage from the first employee. Virginia is the outlier at three.

More important than the threshold is what happens upstream. In both Maryland and DC, if a subcontractor has not secured workers compensation, the contractor above them is liable for it and is treated as the employer for claim purposes. That is the real reason to collect a current workers compensation certificate from every sub on every job, and to check the date on it rather than filing it.

Maryland adds a further wrinkle. The Workplace Fraud Act applies specifically to construction and landscaping and presumes an employment relationship unless the employer can meet a strict test. Knowing misclassification carries a civil penalty of up to 5,000 dollars, and up to 20,000 dollars for someone who advises an employer to do it.

What it costs to get the license wrong

The fines are unpleasant. The contract consequences are worse.

Maryland. Acting as a home improvement contractor without a license is a misdemeanor carrying up to 1,000 dollars or six months for a first conviction, and up to 5,000 dollars or two years after that, with separate civil penalties of 1,500 dollars and 5,000 dollars. Maryland courts have held for decades that an unlicensed home improvement contractor cannot enforce the contract, cannot recover in quantum meruit, and cannot get a mechanic lien. There is some relief for a contractor who substantially complied and got licensed promptly, and an unlicensed subcontractor can still collect from a licensed general contractor, because the rule exists to protect homeowners rather than GCs.

District of Columbia. Working without the right license is a Class 1 infraction. Under the fine schedule effective January 1, 2026 that is 2,549 dollars for a first offense, rising to 5,098, 10,195 and 20,390 dollars. Where an unlicensed sub is used, both the licensed contractor and the unlicensed sub can be cited. DC is harsher than Maryland on payment: a contractor who accepts payment for home improvement work while unlicensed forfeits recovery on both the contract and quantum meruit, and getting licensed afterward does not cure it.

Virginia. Contracting or bidding without a license, or holding the wrong class for the value of the work, is a Class 1 misdemeanor with a fine of up to 500 dollars for each day in violation. The contract is generally unenforceable by the unlicensed contractor, so you can perform the work and be unable to sue to get paid. There is a narrow escape for a contractor who substantially performed in good faith without actual knowledge, but letting a license lapse creates a rebuttable presumption that you knew.

One more worth watching: DC enacted a General Contractor Licensing Amendment Act in late 2024 that would replace the current endorsement scheme with a licensing board, three license types and a guaranty fund. It has not been funded and is not in effect. Several published guides describe it as current law. It is not, yet.

What we would actually check

• Get the endorsement pages, not just the certificate, and confirm completed operations is included.
• Confirm primary and non contributory wording and a waiver of subrogation where the contract calls for them.
• Check the policy dates on every certificate in the file, and re collect at renewal rather than at the next job.
• Match the license class to the actual contract value, especially in Virginia and DC where the class is tied to the number.
• If you work across the line, confirm you hold the right credential in each jurisdiction rather than assuming one covers the others.
• For any DC public job, check the bond requirement at 25,000 dollars rather than at the Maryland threshold you are used to.

We work with contractors and subcontractors across Maryland, Washington DC and Northern Virginia, and this is the kind of thing that is cheap to sort out in advance and expensive to discover during a claim. If you want someone to read the certificates in your file before your next prequalification, send them over.

Frequently Asked Questions

Does a certificate of insurance give me coverage?
No. The ACORD 25 states in its own header that it is informational, confers no rights on the certificate holder, and does not amend or extend the policies listed. It is evidence that a policy existed when it was issued, nothing more.

What is the difference between a certificate holder and an additional insured?
A certificate holder receives evidence and usually notice of cancellation, and has no coverage. An additional insured is an actual insured under the other party policy, and that status exists only through a policy endorsement or a blanket additional insured provision.

Does Maryland require contractors to carry general liability insurance?
For home improvement work, yes. A Maryland Home Improvement Commission license requires general liability of at least 500,000 dollars, raised from 50,000 dollars effective October 1, 2024. There is no state general contractor license for commercial construction in Maryland, so commercial general liability requirements there come from contracts rather than from licensing law.

What insurance does DC require from a general contractor?
DC ties the minimum to the license class, ranging from 500,000 dollars per occurrence at the smallest class up to 2.5 million at the unlimited class. The policy must name the DC Treasurer as an additional insured on a primary and non contributory basis, and the Director must receive 30 days notice before cancellation.

Does Virginia require contractors to carry general liability insurance?
Not for licensure. The Board for Contractors reviews financial responsibility, experience and required coursework, and does not require a general liability policy. In practice nearly every customer will, and their requirements are stricter than the state ones.

What are the Virginia contractor license class thresholds?
After the 2025 amendment, Class A is 150,000 dollars or more per contract or 1,000,000 or more annually, Class B is 30,000 to under 150,000 or 250,000 to under 1,000,000 annually, and Class C is over 1,000 and under 30,000 or under 250,000 annually.

Do I need a separate license for each state in the DMV?
Generally yes. Maryland, DC and Virginia run separate systems with different requirements, and holding one does not satisfy another. A Maryland based contractor working in DC needs a DC Basic Business License with the right endorsement, the required insurance, a bond for home improvement work, and Clean Hands certification, though no DC certificate of occupancy if the business is not located in the District.
