The Public Adjuster's Guide to the Vacancy Clause

Note: This guide is based on standard ISO commercial property and homeowners forms. Always verify specific policy editions and carrier-specific language.

The vacancy clause is one of the most punishing provisions in property insurance. Once a building has been vacant for more than 60 consecutive days, the clause either eliminates coverage entirely for certain perils or reduces payment on all other covered losses by 15%. For public adjusters, vacancy is a threshold issue: if the carrier invokes it successfully, the claim is either dead or deeply discounted before the scope of loss is even discussed.

What Does the ISO Vacancy Clause Actually Say?

The vacancy clause appears under "Loss Conditions" in the ISO Building and Personal Property Coverage Form, CP 00 10. The relevant provision reads:

"When this policy is issued to a tenant, and with respect to that tenant's interest in Covered Property, a building is vacant unless the tenant is customarily using the building to conduct its operations. When this policy is issued to the owner or general lessee of a building, the building is vacant unless at least 31% of its total square footage is: (i) Rented to a lessee or sub-lessee and used by the lessee or sub-lessee to conduct its customary operations; and/or (ii) Used by the building owner to conduct customary operations."

For owners, the test is mathematical: at least 31% of the building's total square footage must be rented and used for customary operations. "Total square footage" includes common areas — hallways, lobbies, stairwells, and mechanical rooms — not just leasable space. This distinction matters. A strip mall where tenants occupy 30% of rentable space may still fall below 31% of total square footage once common areas are included.

For tenants, the test is functional: the building is vacant when the tenant does not have enough business personal property inside it to conduct customary operations. A tenant who moves out but leaves behind a desk and a phone does not meet the threshold.

The Second Circuit addressed the "total square footage" calculation in Keren Habinyon v. Northern Assurance Co. of America (2d Cir. 2012), holding that the 31% threshold must be measured against the building's entire square footage, including common areas, not merely the portion available for lease. That ruling remains the leading authority on how to calculate the occupancy percentage.

"Vacant" vs. "Unoccupied" — A Distinction CP 00 10 Does Not Make

Some older policies and non-ISO forms distinguish between "vacant" (no contents, no people) and "unoccupied" (contents present but no one using the space). The ISO CP 00 10 does not use the term "unoccupied." Its test is activity-based: are customary operations being conducted? A building full of furniture but empty of activity can still be vacant under CP 00 10. Public adjusters should resist the instinct to argue "unoccupied, not vacant" on a standard ISO form — that distinction belongs to a different policy generation.

How Does the Vacancy Clause Work in Commercial Property Insurance?

Once a commercial building has been vacant for more than 60 consecutive days before the date of loss, the vacancy clause imposes a two-tier penalty:

Tier 1 — Total exclusion. The following six perils are excluded entirely:

• Vandalism
• Sprinkler leakage
• Building glass breakage
• Water damage
• Theft
• Attempted theft

Tier 2 — 15% reduction. For all other covered causes of loss (fire, windstorm, hail, explosion, etc.), the insurer reduces the amount it would otherwise pay by 15%.

In Pappas Enterprises, Inc. v. Commerce & Industry Insurance Co. (Mass. 1996), the court held that the 60-day vacancy clock does not reset when the policy renews. If a building was vacant for 45 days at the end of one policy term and remained vacant through the renewal, the clock continued running. This ruling eliminates the strategy of arguing that a renewal creates a new 60-day grace period.

Worked Example: 50,000 Sq Ft Strip Mall

A 50,000 square foot strip mall has one remaining tenant occupying 12,000 square feet — 24% of total square footage. The building has been in this condition for more than 60 days.

Scenario A — Water damage, 24% occupied: Water damage is one of the six excluded perils. The claim is denied entirely. Payment: $0.

Scenario B — Water damage, 32% occupied: A second tenant leases an additional 4,000 sq ft, bringing occupancy to 16,000 sq ft (32%). The building is no longer vacant. The water damage claim is paid in full.

Scenario C — Windstorm, 24% occupied: Windstorm is not one of the six excluded perils, so it is covered — but subject to the 15% reduction. On a $200,000 windstorm loss, the carrier pays $200,000 × 0.85 = $170,000.

Action: On any commercial property claim where occupancy is marginal, measure total square footage (including common areas) against the 31% threshold before engaging with the carrier on the merits. A single percentage point can be the difference between full payment and total denial.

How Does the Vacancy Clause Apply in Homeowners Insurance?

The homeowners vacancy framework is structurally different from commercial. Under the standard HO 00 03, there is no 31% occupancy threshold and no 15% reduction on covered perils. Instead, the homeowners form targets specific perils with outright exclusion after 60 consecutive days of vacancy.

The primary exclusion is for vandalism and malicious mischief: under HO 00 03, the insurer will not pay for loss caused by vandalism and malicious mischief if the dwelling has been vacant for more than 60 consecutive days immediately before the loss. There is no partial payment — the peril is simply excluded.

A functionally related exclusion applies to freezing damage. While the freezing exclusion is technically separate from the vacancy clause, it operates on the same logic: if the dwelling is vacant and the insured did not maintain heat or drain the water system, resulting freeze damage is excluded.

In Adkisson v. Safeco Insurance Co. of Indiana (E.D. Tex. 2024), the court examined whether a homeowner's property qualified as vacant under the policy's 60-day provision, reinforcing that the vacancy determination is a factual inquiry tied to the specific circumstances of occupancy.

In Columbia Lloyds Insurance Co. v. Mao (Tex. App. 2011), the court addressed vacancy in the homeowners context and held that the insurer bore the burden of proving the dwelling was vacant for the requisite period — a meaningful advantage for insureds in Texas jurisdictions.

Action: On homeowners files, do not assume the commercial vacancy framework applies. The homeowners form has no percentage-of-occupancy test and no 15% reduction. The fight is narrower — was the dwelling vacant for 60+ days, and was the peril one that the vacancy provision excludes?

Does the Vacancy Clause Apply to Buildings Under Construction?

Buildings under construction or renovation are generally exempt from the vacancy clause, but the ISO form does not define "under construction" or "renovation." This creates a gray zone that carriers exploit when renovation has stalled or is still in the planning phase.

In Farbman Group, Inc. v. Travelers Indemnity Co. (E.D. Mich. 2006), the court held that a building undergoing active renovation was not subject to the vacancy clause. The key word is "active" — the renovation must be underway, with workers on-site and permits pulled, not merely planned or contemplated. A building where the owner intends to renovate but has not yet begun construction does not qualify for the exemption.

Action: If the insured's building was under renovation at the time of loss, document the status thoroughly: active permits, contractor invoices, work schedules, and photographs showing ongoing work. The exemption depends on demonstrating that construction was actively underway — not that it was merely intended.

Vacancy Clause and Arson

Arson fires on vacant buildings present a nuanced coverage question. Vandalism is one of the six perils excluded entirely after 60 days of vacancy. Carriers sometimes characterize arson as a form of vandalism to invoke the total exclusion rather than the 15% reduction that applies to fire.

In Abudayya v. Country Mutual Insurance Co. (Ill. Cir. Ct. 2024), the court held that an arson fire constitutes a fire loss — a separate peril from vandalism — for purposes of the vacancy clause. The result: fire remains a covered peril subject only to the 15% reduction, not the total exclusion that applies to vandalism.

Dollar impact: On a $500,000 arson fire loss on a vacant building, the carrier's characterization determines the outcome. If arson = vandalism: payment is $0 (excluded peril). If arson = fire: payment is $500,000 × 0.85 = $425,000 (15% reduction). The difference is $425,000.

Action: When a vacant building sustains an arson fire, do not accept the carrier's characterization of the loss as "vandalism." Cite Abudayya and argue that fire is the operative peril, subject to the 15% reduction rather than total exclusion.

The Vacancy Permit Endorsement

ISO Form CP 04 50 — the Vacancy Permit endorsement — suspends the vacancy exclusions for a specified period. When attached to the policy, the endorsement overrides the vacancy clause penalties, allowing coverage to continue even though the building would otherwise be considered vacant under the standard 60-day provision.

The critical timing requirement: the vacancy permit must be obtained before the 60-day clock expires. If the building has already been vacant for more than 60 days when the endorsement is requested, it may be too late — carriers are not obligated to issue the endorsement retroactively.

Even with the vacancy permit in place, some perils may still be excluded or restricted. Vandalism and sprinkler leakage are commonly carved out of vacancy permit endorsements depending on the carrier's underwriting appetite. Always read the specific endorsement language.

Action: At intake, check whether the policy includes CP 04 50. If it does, confirm the endorsement's effective dates and any peril-specific exclusions that survive the permit. If it does not, and the building is approaching the 60-day vacancy threshold, advise the insured to request the endorsement immediately.

Property Types Most Vulnerable to the Vacancy Clause

Certain property types are disproportionately exposed to vacancy clause disputes:

• Seasonal businesses: Properties that close for an off-season — beach rentals, ski lodges, agricultural operations — can easily exceed 60 consecutive days of non-use.
• Strip malls near the 31% threshold: A single tenant departure can push occupancy below 31% of total square footage, triggering the clause without the owner realizing it.
• Properties in lease-up: Newly constructed or recently acquired commercial buildings that have not yet secured tenants are vacant from day one.
• Buildings with stalled renovations: If construction stops — due to permitting delays, financing issues, or contractor disputes — the construction exemption may no longer apply.
• Inherited and estate properties: Properties passing through probate or estate administration often sit vacant for months while legal proceedings unfold.

In Sinjel v. Ohio Casualty Insurance Co. (S.D. Miss. 2023), the court examined vacancy in the context of a property that had been transitioning between uses, reinforcing that the vacancy determination turns on the specific facts of occupancy and use at the time of loss.

Vacancy Clause Comparison: Commercial vs. Homeowners

Vacancy Clause FAQ

Does the vacancy clause apply if a building has furniture but no occupants?

For commercial policies, yes — the test is whether 31% of total square footage is rented and used for customary operations, not whether the building contains property. For homeowners, the answer is fact-dependent: courts examine whether the dwelling is being used as a residence, and the presence of personal property is one factor but not dispositive.

Does the 60-day vacancy period reset when the policy renews?

No. In Pappas Enterprises, Inc. v. Commerce & Industry Insurance Co. (Mass. 1996), the court held that the 60-day clock runs continuously and does not reset at policy renewal. Vacancy days from the prior term carry forward.

Can a carrier deny a fire claim on a vacant building?

Fire is not one of the six excluded perils under the commercial vacancy clause. A fire loss on a vacant building is covered, subject to a 15% reduction. If the carrier characterizes an arson fire as "vandalism" to invoke the total exclusion, cite Abudayya v. Country Mutual Insurance Co. (Ill. Cir. Ct. 2024), which held that arson fire is a separate peril from vandalism.

Does the vacancy clause apply during renovation?

Buildings under active construction or renovation are exempt from the vacancy clause. However, the renovation must be actively underway — not merely planned. In Farbman Group, Inc. v. Travelers Indemnity Co. (E.D. Mich. 2006), the court required evidence of ongoing construction activity to support the exemption.

What is a vacancy permit endorsement?

ISO Form CP 04 50 is the Vacancy Permit endorsement. It suspends the vacancy clause exclusions for a specified period. The endorsement must be obtained before the 60-day vacancy period expires. Even with the permit, certain perils — typically vandalism and sprinkler leakage — may remain excluded.

Vacancy Clauses and Policy Analysis

The vacancy clause is a binary switch: once the carrier establishes that the building was vacant for more than 60 consecutive days, the claim either loses entire categories of coverage or takes an automatic 15% haircut. The occupancy percentage, the peril classification, the construction exemption, and the presence of a vacancy permit endorsement are all determinable from the policy and the facts available at intake.
