If a client, property manager, or city asks for a certificate of insurance (COI), you can usually get one the same day from your agent. It's a one-page proof that your policies (general liability, auto, workers’ comp, etc.) are active and show the limits and endorsements the hiring party wants. Provide the exact certificate‑holder name and the contract wording for any additional‑insured language, and the agent will issue an ACORD‑style COI or attach the endorsement your client asked for. As of October 2026, most brokers and carriers handle these requests electronically and can issue corrected certificates quickly.
Below you'll find what a COI actually proves, the coverages hiring parties commonly demand from landscapers, the exact information your agent needs, sample COI wording you can paste into contracts, a decision checklist for tough requests, and the 10 questions you must ask your agent before you send a COI.

Key takeaways
- A COI is evidence of insurance, not the insurance policy — the policy language controls coverage. (csusb.edu)
- Commercial clients and municipalities commonly require general liability and commercial auto limits and to be named as an Additional Insured; wording matters (endorsement form, primary/noncontributory, waiver of subrogation). (dot.ca.gov)
- Most agents can issue or correct a COI the same day if you provide exact certificate‑holder and contract text; generating the COI itself is usually free — the cost is the policies, not the certificate.
- Keep a templated COI packet (exact names/addresses, contract clause, invoicing info) so you can respond fast and avoid losing jobs.
What is a certificate of insurance and why do clients ask for one?
A certificate of insurance (COI) is a standardized one‑page summary showing which policies you have, their policy numbers, effective dates, and limits. It’s issued by your insurer or broker as proof that coverage existed on the issue date. A COI is evidence only — it doesn’t change policy terms or create coverage the policy doesn’t already provide. Clients, landlords, property managers, general contractors, and public agencies use COIs to confirm you meet contract‑required coverages and to make sure they can be listed as an Additional Insured (AI) when needed. Municipal contracts and permit offices often demand COIs before allowing work or pulling permits. The COI speeds contract approval and signals you’re commercially responsible — but the policy and any attached endorsements decide whether a claim will be covered.
What coverages and limits do clients commonly require from landscapers?
There’s no single national rule — requirements vary by client, job type, and jurisdiction — but commercial contracting and municipal checklists repeatedly show the same baseline:
- Commercial general liability (CGL): often required at $1,000,000 per occurrence with $2,000,000 general aggregate for many properties and municipal contracts.
- Commercial auto liability: hired/non-owned and owned autos listed, commonly $1,000,000 combined single limit on commercial contracts.
- Workers’ compensation: statutory limits in the state where the work occurs; many contracts also ask for $1,000,000 employer’s liability. (purchasing.idaho.gov)
- Umbrella/excess: required on larger contracts to bump limits over the CGL/auto minimums. Municipal and institutional contracts are the best evidence of what’s typical: many city procurement rules and project specs explicitly list $1,000,000/$2,000,000 and require the city be named as an Additional Insured with specified endorsement language. Always check the job’s contract or RFP for exact wording — a certificate that lacks the precise endorsement the client specified can be rejected even if your limits meet the dollar amounts.
How to get a certificate of insurance (step-by-step)
- Read the contract or client request word‑for‑word. Copy the certificate‑holder name and the exact Additional Insured / waiver wording. Many rejections come from misspelled entity names or partial legal names.
- Call or email your insurance agent/broker and paste the exact text they requested into the message. Tell them which policies you want shown (GL, Auto, WC, Umbrella) and whether the client needs AI endorsement, waiver of subrogation, or primary/noncontributory language.
- Provide any contract or RFP attachment that shows the requirement so the agent can match it exactly and attach the correct ISO endorsement (CG 20 10 / CG 20 37 / CG 20 38 variants are common). If the client names a government entity, include whether the endorsement must be “to the extent of operations” or for “ongoing and completed operations.” (prismrisk.gov)
- Ask for the COI via email and request an attached copy of the actual Additional Insured endorsement (not just the certificate line). If the client needs “primary and noncontributory” status, make that explicit.
- Review the returned COI: confirm the insured name matches your legal business name exactly, the certificate holder is correct, the limits and policy dates are correct, and the requested endorsement language is attached or referenced. If anything is wrong, ask the agent to correct it and reissue the certificate. Many agents can reissue same‑day if they have the contract text.
Most agents treat COI issuance as routine administrative work and will produce a compliant COI quickly if you give exact names and contract language. If you expect frequent requests, set up an online COI portal with your broker so you can download certificates instantly.

What endorsements and certificate wording do clients most often demand?
Clients don’t just want limits — they want contract protections. The most common requests are:
- Additional Insured endorsement (AI): names the client on your CGL policy for liability arising from your work. Specific ISO endorsements (e.g., CG 20 10, CG 20 37) control scope; the contract should specify or cite the endorsement form.
- Primary and Noncontributory: makes your policy primary to the additional insured’s policy so the client’s insurance does not have to contribute first. This must be shown in the endorsement or via explicit policy language.
- Waiver of Subrogation: prevents your insurer from suing the client to recover paid claims. Contracts sometimes require waivers for both General Liability and Workers’ Comp.
- Notice of Cancellation: entities often require 30 days’ prior written notice of cancellation/nonrenewal (10 days for nonpayment for some insurers). This is typically a policy endorsement and should be noted on the COI or in the attached endorsement. (sandiego.gov) If a client asks only for “additional insured,” ask whether they want the AI for ongoing operations only or for ongoing and completed operations, and whether they need the CG 20 form number. A COI that says “Additional Insured: as required by written contract” is ambiguous and may be rejected. Use exact language.
Comparison: common policies landscapers show on a COI
| Coverage type | What it covers | Who needs it | Typical certificate trigger |
|---|---|---|---|
| Commercial General Liability (CGL) | Third‑party bodily injury and property damage, premises and operations, products/completed ops | All landscapers doing client work on others’ property | Required on almost every commercial/residential contract |
| Commercial Auto Liability | Liability from owned, hired and non‑owned vehicles | Landscapers who use trucks, trailers, ATVs on job sites | Required when trucks/vehicles are used to perform work |
| Workers’ Compensation & Employers’ Liability | Employee injury benefits; employer liability for workplace claims | Any business with employees (state rules vary) | Required by state law if you have employees |
| Inland Marine / Equipment Floater | Tools, mowers, trailers, equipment in transit or stored offsite | Firms with expensive mobile equipment | Requested when client wants protection for your equipment losses or as contract condition |
| Umbrella/Excess Liability | Additional limits over primary policies | Companies needing higher limits for larger contracts | Often requested to meet contract limits beyond CGL/auto |
| Typical contract minimums often seen on COI requests include $1,000,000 per occurrence and $2,000,000 aggregate for CGL and $1,000,000 for commercial auto — municipal procurement documents and property managers commonly use these figures. Always rely on the contract’s exact wording. | |||

Common mistakes that make COIs get rejected (so you avoid them)
- Misspelling or using an incomplete legal name for the certificate holder. If the hiring party’s legal entity is “ACME Property Management LLC,” using “ACME Property” will get it rejected.
- Sending only the COI without the actual Additional Insured endorsement when the contract asks for it. Many buyers insist on receiving the endorsement page, not just the COI line.
- Accepting vague language like “as required by contract” instead of pasting the contract’s endorsement text for the agent to attach.
- Not confirming automobile coverage includes hired and non‑owned autos when you use rental trucks or employee personal vehicles for work.
Decision checklist: should you agree to a tough COI demand?
- Is the request from a public agency or large property manager with standard clauses? If yes, get the exact clause and ask your broker to confirm the endorsement form they’ll attach.
- Will adding the Additional Insured endorsement or agreeing to primary/noncontributory materially change your coverage or increase premiums? Ask your broker to confirm — many endorsements carry no surcharge but some carriers limit endorsement scope.
- Does the contract require higher limits than your policy provides? If so, you’ll need an umbrella/excess policy or to negotiate limits. Don’t misrepresent your limits on the COI.
- If the request includes a waiver of subrogation, check whether your insurer will allow it and whether it applies to workers’ comp — not all carriers grant waivers automatically.
What does typical client insurance wording look like?
Clients usually supply their own insurance clause, and theirs controls. This example only shows the kind of wording many contracts use, so you know what to hand your agent. It is an illustration, not legal advice or a template to sign (replace the bracketed parts with the client's exact legal name):
- Certificate holder: [Exact legal name and address of hiring party].
- Additional Insured: “[Hiring party full legal name], its officers, directors, agents and employees” shall be named as Additional Insured on the Contractor’s Commercial General Liability policy with respect to liability arising out of Contractor’s operations and for ongoing and completed operations. CG 20 10 or equivalent endorsement must be attached.
- Primary/Noncontributory: The Contractor’s insurance shall be primary and noncontributory to any insurance available to the Additional Insured.
- Waiver of Subrogation: Waiver of subrogation in favor of the Additional Insured is required for General Liability and Workers’ Compensation (where allowed by law).
- Cancellation: Thirty (30) days’ prior written notice of cancellation or nonrenewal, or ten (10) days for nonpayment.
Ask your agent to attach the endorsement page that fulfills these points rather than relying on certificate text alone. Municipal procurement guides and city contracts commonly require precisely this level of detail.

How fast will you get a COI and does it cost extra?
Most brokers can issue a standard COI the same day you request one if your policies are active; many carriers and brokers now provide online portals where you can download certificates immediately. Generating the COI is typically administrative and provided at no charge — the policy premium is the actual expense. If a client demands special endorsements or a nonstandard endorsement form, the insurer may need to process an endorsement; that can take a few business days depending on the carrier. If you expect regular institutional work (HOAs, municipalities, property managers), ask the agent to set up a blanket/automatic process to deliver COIs and AIs so you don’t have to request them each time.
How to compare agent/broker service for COIs
When vetting agents, use these practical criteria:
- Speed: ask “how fast can you turn COIs and AI endorsements?” — expect same‑day for standard requests.
- Endorsement handling: confirm they will attach the actual endorsement page (not just a certificate line) and will reference ISO form numbers when the client asks.
- Portal & tracking: if you manage multiple accounts, a portal that stores issued COIs and auto‑sends renewals saves time.
- Licensing & carrier appointments: confirm the agent is licensed in your state and has access to markets that insure landscaping risk.
Questions to ask your agent (copy-paste)
- Exactly what endorsement form will you attach to name the client as Additional Insured (please cite ISO form number if applicable)?
- Can you make the contractor’s insurance primary and noncontributory and attach that endorsement?
- Will a waiver of subrogation be allowed for Workers’ Comp and General Liability for this contract?
- How fast can you issue a corrected COI if the client rejects the first one? (Expect same‑day or 1–2 business days.)
- Does this endorsement or change trigger any premium or underwriting review? If yes, what’s the likely timeline?
Frequently asked questions
Can I create and sign my own certificate of insurance?
No. Only a licensed insurer or an authorized agent/broker can issue a legitimate COI. Self‑issued COIs are meaningless and using one can amount to fraud.
If the COI lists the right limits but doesn’t have the endorsement attached, is that enough?
Often not. Many clients require the endorsement page itself; a certificate line that says “Additional Insured: per contract” can be rejected. Ask your agent to attach the endorsement.
Do COIs prove coverage for past work (completed operations)?
A COI is a snapshot of coverages as of the issue date. To prove coverage for completed operations you may need the right endorsement language and appropriate policy dates; contracts often specify ongoing and completed operations for the AI endorsement.
What if my client demands limits my carrier won’t offer?
If the client’s required limits exceed your policy, you must either buy an umbrella/excess policy, negotiate limits with the client, or decline the job. Never misstate limits on a COI.
Is there a central database clients use to verify COIs?
Large owners and general contractors often use certificate‑tracking systems and vendor portals that verify carrier NAIC numbers and policy dates; they may also call the issuing agent to confirm authenticity. If you submit frequently, ask your broker about integrating with the client’s portal.
Bottom line
Get a COI by asking your agent for one and providing the exact contract wording plus the precise legal name and address of the certificate holder. Most brokers can issue or fix a COI the same day if you give them the contract text and required endorsements; the certificate itself is usually administrative and provided at no extra charge. Save a COI packet with common certificate‑holder names and sample endorsement text, and keep an agent who responds quickly — that’s the fastest way to stop paperwork from costing you jobs. Next steps: copy the sample COI clause above into your client proposals and send that wording to your agent when you request a certificate. If you don’t yet have the right policies, talk to an agent about bundling CGL, commercial auto, workers’ comp, and an umbrella so you can meet common contract minimums without last‑minute scrambling.
