A 220-unit condominium association required all contractors working on common elements to name the association as additional insured on their general liability policies. The requirement was in the standard contractor agreement template that management used for every hire. The COIs on file for the current painting contractor showed "Condominium Association of [Building Name] named as additional insured."

When a painting crew member was injured in a common area and filed suit against the association as well as the painting company, the association's attorney tendered the defense to the painting company's GL carrier. The carrier denied the tender.

The carrier's position: the painting company's policy had been endorsed to add additional insured status "per written contract" under form CG 20 26 - a blanket additional insured endorsement. But the carrier argued that the specific additional insured requirement in the contractor agreement constituted a "hold harmless agreement" rather than a contract requiring the contractor to add the association as an insured, and that the association was not entitled to additional insured defense under the policy terms.

The association spent $95,000 in defense costs before settling. The additional insured language on the COI had looked correct. The underlying endorsement form created a coverage dispute that cost six figures to resolve.

When a condominium association hires a contractor to work on common elements - the lobby, the parking structure, the pool, the roof, the building envelope - the association becomes legally connected to the contractor's work. If that contractor causes injury or property damage, the injured party will typically name both the contractor and the association in any lawsuit.

Without additional insured status on the contractor's policy, the association must fund its own defense from its own master policy or out of pocket. Its master policy responds - but the claim draws against its aggregate limits, creates a claims history, and drives future premium increases.

With proper additional insured status, the contractor's general liability policy:

  • Provides defense coverage to the association for covered claims arising from the contractor's work
  • Responds on a primary basis, before the association's master policy
  • Preserves the association's master policy limits for association-specific exposures

Additional insured status is the legal mechanism that aligns insurance coverage with where the exposure actually originates: the contractor's work.

Standard Additional Insured Language in Condo Rules and Contracts

Condo associations specify additional insured requirements in multiple documents, and the language matters.

In vendor/contractor agreements:

"Contractor shall name the Condominium Association of [Name], its board of directors, officers, and property management company as additional insureds on all commercial general liability policies, on a primary and non-contributory basis, for both ongoing and completed operations."

In community rules and regulations (for unit owner contractors):

"All contractors performing work within or affecting units or common elements shall maintain commercial general liability insurance naming [Association Name] as additional insured. A certificate of insurance evidencing such coverage shall be submitted to the management office prior to commencement of any work."

Key language elements to include:

  • Specific association legal name (not a shorthand or building address)
  • "Primary and non-contributory" basis
  • "Ongoing and completed operations" (or reference to both CG 20 10 and CG 20 37 endorsements)
  • Management company named if applicable
  • Board members named individually if required by the bylaws or D&O insurer

The Checkbox vs. Endorsement Problem

This is the most critical concept in additional insured compliance: the COI checkbox is not a guarantee of endorsement.

When a broker issues an ACORD 25 certificate, there is no checkbox for "additional insured." Instead, the broker types additional insured language into the Description of Operations field (Box G). This can be done accurately, inaccurately, or misleadingly - and the certificate does not prove that any endorsement was actually attached to the underlying policy.

The three most common versions of the problem:

Version 1: The generic statement. The COI states "Additional insured as required by written contract" without naming the association or referencing a specific endorsement form. This language does not confirm that an endorsement exists or that the association is actually added. If there is no underlying contract requiring the contractor to name the association as AI, the insurer may take the position that no additional insured status was triggered.

Version 2: The wrong endorsement. The policy has been endorsed under CG 20 26 (Blanket Additional Insured - Owners, Lessees or Contractors) rather than CG 20 10 and CG 20 37. CG 20 26 is a blanket endorsement that adds AI status "as required by written contract." It is subject to coverage disputes about what the contract actually requires. CG 20 10 (ongoing operations) and CG 20 37 (completed operations) are schedule endorsements naming the additional insured directly - they provide clearer, more reliable protection.

Version 3: The endorsement with limiting conditions. The endorsement has been issued but contains conditions that limit coverage in claim scenarios. Common limitations include: coverage applies only to ongoing operations (not completed operations), coverage is limited to the specific project described in the endorsement, or coverage is subject to the policy's contractual liability exclusion.

Endorsement Type How It Appears on COI Risk
No endorsement - broker notation only "Additional insured per contract" Carrier may deny tender; no policy basis
CG 20 26 (blanket) "Additional insured as required by contract" Coverage dispute on what contract requires
CG 20 10 only "Additional insured - ongoing operations" Gap for completed operations claims
CG 20 10 + CG 20 37 (schedule) "Additional insured - ongoing and completed ops" Strongest position; clearest coverage

How to Verify Actual Additional Insured Status

For major projects and high-risk vendors, verifying additional insured status requires more than reading the COI.

Request endorsement documentation. Ask the contractor's broker to provide copies of the additional insured endorsements - specifically, identify the endorsement form number (CG 20 10, CG 20 37, or CG 20 26) and request the actual endorsement page, not just the declarations.

Review the endorsement text. Confirm:

  • The association's full legal name appears in the endorsement (for schedule endorsements)
  • The basis is primary and non-contributory (or request a separate endorsement for this)
  • Completed operations coverage is included if required

Check the basis language. If the association's contract requires "primary and non-contributory" additional insured status, confirm that language appears in the endorsement or in a separate additional endorsement addressing the primary and non-contributory requirement.

Common Deficiencies in Contractor COIs for Condos

Based on common patterns in condo COI compliance reviews, the most frequent deficiencies are:

  1. Missing additional insured entirely - COI submitted by contractor without any AI notation; broker did not add it.

  2. "Per written contract" only - No named insured on the AI notation; coverage depends on underlying contract language that may not trigger.

  3. Primary and non-contributory missing - AI status confirmed but not on a P&NC basis; association's own coverage becomes contributory.

  4. Ongoing operations only - No CG 20 37 for completed operations; gap for post-project claims.

  5. Wrong association name - Association nickname or address used instead of legal entity name.

  6. Management company not named - Contract requires management company as additional insured; COI names association only.

Bramble reads the association's vendor agreements and community rules, extracts the additional insured requirements, and compares the submitted COI against those specific requirements. When AI language is missing, insufficient, or incorrect, Bramble flags the specific deficiency with the contract language that is not satisfied - so the property manager knows exactly what to request from the contractor's broker.

FAQ

Frequently asked questions

What does 'additional insured' mean for a condominium association?

An additional insured endorsement on a contractor's general liability policy extends the contractor's coverage to the condominium association as if the association were also named on the policy. This means that if someone is injured on common element work performed by the contractor, the contractor's insurer defends and indemnifies the association — not just the contractor. Without this endorsement, the association's own master policy absorbs the loss.

Is the additional insured checkbox on a COI enough?

No. The checkbox on an ACORD 25 certificate is informational only — it does not by itself create coverage. What creates coverage is the actual endorsement attached to the policy, typically CG 20 10 (ongoing operations) and CG 20 37 (completed operations) for general liability. Boards and managers should request copies of the actual endorsement forms — not just the certificate — for any contractor working on the building's structural, mechanical, or common elements.

What endorsements should a condo association require?

For most condo contractors: (1) CG 20 10 for ongoing operations additional insured, (2) CG 20 37 for completed operations additional insured (critical for any work that creates a continuing condition — roofing, waterproofing, structural), (3) a waiver of subrogation in favor of the association on both general liability and workers' compensation, and (4) primary and non-contributory wording on the additional insured endorsement so the contractor's policy responds before the association's master policy.

How do you verify a contractor's additional insured status is real?

Two-step verification: (1) request the actual endorsement form from the contractor or their broker — not just the COI — and confirm the form number matches what your contract requires (CG 20 10, CG 20 37, etc.), and (2) verify the policy is in force on the date you're checking by calling the carrier or using a contract-to-COI verification platform that pulls policy status from the carrier directly. Roughly 31% of condo contractor COIs have AI status that does not actually exist when verified at the policy level.

What happens if a contractor's COI is missing additional insured status?

If a claim arises from the contractor's work and the additional insured status is missing or invalid, the association is exposed in three ways: (1) the contractor's insurer is not obligated to defend or indemnify the association, (2) the association's own master policy will be triggered, increasing premiums and potentially the deductible, and (3) the association's directors and officers may face board-level liability for failing to enforce the contract requirement. The fix is to halt the contractor's work until a corrected COI and endorsement are produced.

Do small condo contractors really need to provide endorsements?

Yes — and the size of the contractor is not a useful proxy for the size of the loss. A $400 painting job can produce a $1M premises liability claim if a passerby is injured. The standard practice is to require the same additional insured endorsements from every contractor working on common elements, regardless of the contract size. If a small contractor cannot produce the endorsements, that is a signal that their carrier may not have actually issued them, and the association should not allow the work to proceed.
