A general contractor’s liability policy can cover an indemnity promise when the contract is an “insured contract” and you are taking on another party’s liability for injury or property damage to someone else. Arizona law voids some indemnity wording, and endorsements on your policy can narrow what is covered, so the clause and your forms have to be read together.
For an Arizona general contractor, the practical question before signing is specific: “If this owner is sued over an injury on our project, what did we just promise to pay, and will our policy pay it?” This guide covers how indemnity clauses interact with commercial general liability (GL), what Arizona’s anti-indemnity statutes allow, and what to check before the next contract.
Does general liability cover an indemnity clause in a construction contract?
Often, within limits. An indemnity clause is a contract promise to pay for, defend or hold harmless another party for certain claims. GL policies exclude liability you take on by contract, with two exceptions that matter to contractors. As IRMI’s explanation of contractual liability describes, the exclusion does not apply to liability you would have even without the contract, or to liability assumed in an “insured contract.”
In the standard ISO form, an insured contract includes the part of any contract related to your business under which you assume the tort liability of another party to pay for bodily injury or property damage to a third person. That covers the typical owner-contract promise to protect the owner when a visitor or worker sues over a jobsite injury. It does not turn GL into coverage for every promise in the contract:
- Not your own losses: agreeing to pay for delays, defective work or the owner’s own property is a different question from assuming tort liability to a third party.
- Not professional services: the standard definition excludes indemnifying architects, engineers or surveyors for their professional work.
- Not some railroad work: construction or demolition near railroad property is carved out and usually needs separate coverage.
What indemnity does Arizona law allow in construction contracts?
Arizona limits how far an indemnity clause can reach, and the rule depends on who you are contracting with. These summaries are general education, not legal advice; have counsel review the specific contract.
- Private projects: A.R.S. § 32-1159 makes a clause in a construction or architect-engineer contract void and unenforceable to the extent it requires you to indemnify, hold harmless or defend another party for loss or damage resulting from that party’s sole negligence.
- Public projects: for contracts with the state and political subdivisions, A.R.S. § 34-226 limits indemnity to the extent the loss is caused by the negligence, recklessness or intentional wrongful conduct of the contractor, its employees or subcontractors. Broader defend, indemnify, insure or hold-harmless wording is void.
- Accommodation access: both statutes allow a contractor to fully indemnify a third party who lets the contractor use its property as an accommodation for work performed for someone else.
Because § 32-1159 applies only to sole negligence, a private owner can still ask you to cover losses where it shares fault. That is the range where your policy wording does the most work.
Which policy endorsements narrow contractual liability coverage?
Two ISO endorsements are worth finding on your forms schedule. CG 24 26 amends the insured contract definition so coverage applies only when the injury or damage is caused, in whole or in part, by you or those acting on your behalf. In practice, that removes coverage for promises to pay for losses where you had no fault at all. CG 21 39 removes paragraph f of the definition entirely, so a typical construction indemnity clause would no longer be an insured contract.
Some insurers use their own wording with the same effect. Ask for the actual endorsements, not a quote summary, and compare them with the indemnity language in your standard owner and general contractor agreements.
Who pays the other party’s defense costs?
Many clauses require you to defend the owner as well as indemnify it. According to IRMI’s analysis of insured-contract defense, the standard GL form can pay an indemnitee’s defense in two ways:
- Outside your limits, as supplementary payments, when conditions are met and kept: you and the indemnitee are named in the same suit, the insurer sees no conflict of interest, both of you ask the insurer to defend with the same counsel, and the indemnitee cooperates with the investigation and shares the suit papers.
- Inside your limits, as damages, when those conditions are not met. In that case, defense costs reduce the limit left for any settlement or judgment.
That difference matters most on a serious injury claim, where defense costs can consume a large share of a limit. It is also one reason contracts often pair indemnity with an umbrella or excess requirement.
How do common indemnity clauses compare?
Hypothetical Arizona scenario: A general contractor signs a private commercial build-out contract in Phoenix. A delivery driver trips over materials staged by a subcontractor and sues the owner and the general contractor. The owner tenders its defense to the general contractor under the contract, and the general contractor tenders to its subcontractor under the subcontract.
| Clause or situation | Arizona and policy questions | Record to collect |
|---|---|---|
| “Broad form”: you cover the owner even for its sole negligence | Private: void to the extent of the owner’s sole negligence under § 32-1159. Public: limited by § 34-226. | Signed contract and every amendment |
| Owner shares fault with you or a subcontractor | Often enforceable on private work; is it an insured contract under your forms, and does CG 24 26 apply? | Forms schedule and all endorsements |
| “To the extent caused by” your negligence | Matches the public-contract standard; usually the narrowest promise to make | Contract clause and incident facts |
| Duty to defend the owner | Are supplementary-payment conditions met, or will defense erode limits? | Suit papers, tender letters and counsel agreement |
| Indemnity of the owner’s architect or engineer | Professional services are excluded from the standard insured contract definition | Design responsibilities and any professional liability policy |
| Your subcontractor indemnifies you | Does the subcontract flow down equal or broader protection, and does the subcontractor’s policy support it? | Subcontract, certificate and endorsements |
Indemnity is a promise in a contract; additional insured status is a right under another party’s policy. Owners usually ask for both. The additional insured and waiver guide covers that side, and the subcontractor risk guide covers what to collect from downstream trades.
What should you check before signing the next contract?
Use this checklist to turn “Are we covered for the indemnity clause?” into specific questions your broker and attorney can answer.
- Is the project public or private? That decides whether § 34-226 or § 32-1159 applies, and how broad the clause can be.
- Whose fault does the clause cover? Look for “sole negligence,” “regardless of fault,” “to the extent caused by” and “arising out of.”
- Does the clause require you to defend, and from when? A duty to defend from the first allegation is broader than reimbursing costs later.
- Does your policy treat this as an insured contract? Ask for CG 24 26, CG 21 39 or any similar contractual-liability endorsement on your forms schedule.
- Are design responsibilities involved? Design-build or delegated design can raise professional liability questions that GL does not answer.
- Do your limits fit the promise? Compare occurrence, aggregate and umbrella limits with the contract and the project’s exposure.
- Do your subcontracts match? Flow down indemnity, additional insured and limit requirements, and collect the endorsements, not only certificates.
Keep a contract file for each project: the signed agreement and amendments, the insurance exhibit, certificates and endorsements received, and any tender letters. When a claim arrives, report it to your insurer promptly using your policy’s instructions, and send any tender of defense you receive to your agent and insurer the same day.

Does my general liability policy cover the indemnity clause in my owner contract?
It can, when the clause makes the contract an insured contract: you assume another party’s tort liability for injury or property damage to a third party. Endorsements such as CG 24 26 or CG 21 39 can narrow or remove that coverage, so check your forms.
Is a broad form indemnity clause enforceable in Arizona?
Not to the extent it covers the other party’s sole negligence on a private construction contract, under A.R.S. § 32-1159. Public contracts are limited further by A.R.S. § 34-226. Have an attorney review the specific wording.
What is the difference between indemnity and additional insured status?
Indemnity is your contractual promise to pay for or defend another party. Additional insured status gives that party rights under your insurance policy directly. Owners usually require both, and each depends on different wording.
Do defense costs for the owner reduce my policy limit?
They can. Under the standard form, an indemnitee’s defense can be paid outside your limits as supplementary payments if specific conditions are met; otherwise it is paid as damages, which reduces the limit available.
