What does co-op building property insurance cover?
Co-op building property insurance is the blanket policy a cooperative corporation carries on the entire building it owns, insuring the structure, mechanicals, and apartment interiors at replacement cost. Because the corporation holds title and shareholders hold proprietary leases, there is no bare-walls form choice. It excludes a shareholder's furnishings, which sit on an HO-6.
Why a co-op insures the whole building on one blanket policy
A housing cooperative is a corporation that owns the entire building; residents buy shares and hold a proprietary lease, not a deed.
The corporation is on title for the whole structure
Because shareholders hold proprietary leases rather than deeds, the corporation owns the roof, mechanicals, and apartment interiors alike.
An underlying mortgage sits on the building
Most co-op corporations carry a blanket underlying mortgage, and that lender requires replacement-cost settlement and a mortgagee clause.
The stock is older and urban
Housing cooperatives concentrate in pre-war urban buildings with elevators, steam heat, and central boilers.

What's covered, and what isn't
In the policy
Co-op building property insurance on one blanket limit
The corporation owns the whole structure, so co-op building property insurance covers the roof, exterior walls, lobbies, hallways.
Replacement-cost settlement for the underlying-mortgage lender
The blanket underlying mortgage requires the master policy to settle on a replacement-cost basis with no depreciation and to name the lender as mortgagee.
Increased cost of a code-compliant rebuild
Ordinance-or-law coverage pays the added cost of rebuilding an older cooperative to current code after a covered loss.
Building systems, boilers, and steam heat
Equipment breakdown covers sudden mechanical or electrical failure of the central boiler, steam-heat plant, elevators.
Loss of maintenance charges after a covered loss
Business income on a co-op replaces the maintenance charges the corporation loses when apartments are uninhabitable during a rebuild, not owner assessments.
Not in the policy
A shareholder's furnishings and betterments
Personal property, and any improvement a shareholder made inside their apartment, are the shareholder's responsibility, not the corporation's.
Covered by each shareholder's HO-6 co-op policy
Board decisions and proprietary-lease disputes
A suit over a rejected purchase application, a lease-termination fight, or a wrongful board decision is a management-liability claim against the directors.
Covered by Directors & Officers
Theft of corporate funds and managing-agent dishonesty
A managing agent or board member diverting the corporation's reserves, maintenance receipts, or underlying-mortgage escrow is a fidelity loss.
Covered by Crime & Fidelity
Injury to residents and guests in common areas
A slip in a lobby, a fall on an icy sidewalk, or an elevator injury is a bodily-injury claim against the corporation, not damage to the building.
Covered by General Liability
Earthquake and flood
Standard property forms exclude shake and rising water.
Covered by Earthquake / flood policy
Claims commercial property pays
A co-op loss runs through the corporation, not a patchwork of owner policies, so the blanket limit, the valuation, and the building's age decide the outcome. These are the property claims cooperative corporations actually face, with the typical cost to repair and settle each.
Central boiler or steam-heat plant failure
The central boiler or steam riser fails in winter, cutting heat to every apartment and damaging the mechanical room and floors below.
$100K–$2M+
Fire or water loss through an older building
A fire spreads through a shared shaft or a riser fails and water travels down through several apartments.
$250K–$5M+
Ordinance-or-law rebuild on a pre-war structure
A covered loss damages a pre-war cooperative, and the city requires the rebuild to meet current electrical, fire, and accessibility codes.
$150K–$3M+
Coinsurance shortfall on a stale valuation
The building was insured to a replacement value set years ago and never re-appraised.
$50K–$1M+
Ranges are typical repair and settlement bands for these claim types, not a quote. Actual exposure depends on construction, building age, the central systems, the blanket limit, and the valuation basis.
What hoa buyers are required to carry
The limits contracts and statutes set for this line, and what moves your premium and terms.
- Underlying-mortgage lender
- 100% RC + mortgagee clause
- Fannie Mae / Freddie Mac (share loans)
- 100% RC, deductible ≤ $50,000
- Governing documents
- Coverage per the proprietary lease
The blanket mortgage requires the master policy to insure 100% of replacement cost on a replacement-cost settlement basis, with the lender named as mortgagee and lender's loss payee on an ACORD 28. A shortfall blocks a refinance.
For a conforming share loan, the master policy must insure 100% of the project improvements' replacement cost, settle on a replacement-cost basis, and cap the single-occurrence deductible at $50,000 per unit under Lender Letter LL-2026-03, effective July 1, 2026.
The certificate of incorporation, bylaws, and proprietary lease dictate what the corporation must insure and to what value. The board can be liable to shareholders for failing to maintain the blanket coverage the proprietary lease promises.
- Blanket limit and valuation
- Replacement cost of the entire building is the primary rating base, and because the corporation insures the whole structure on one limit.
- Building age, construction, and central systems
- Pre-war and mid-century construction, a central boiler, steam heat, and elevators rate very differently from newer stock.
- Loss history and water-damage frequency
- Multi-year loss runs set the rate and the deductible.
- Location and catastrophe exposure
- Urban location, high-rise height, and coastal or high-wind exposure drive the rate and can force a percentage named-storm deductible.
Endorsements that close the gaps
The base form is the start. These add-ons are where the policy gets built to fit hoa.
Ordinance or law coverage
Splits into three parts: loss to the undamaged portion a code officer condemns (Coverage A), demolition (Coverage B).
Agreed value
Waives the coinsurance clause when the carrier and corporation set the insured value up front, removing the coinsurance-penalty risk on a partial loss.
Equipment breakdown (boiler and machinery)
Covers sudden mechanical or electrical failure of central boilers, steam plants, elevators, and pumps that a standard property form excludes.
Business income (loss of maintenance charges)
Replaces the maintenance charges the corporation loses while apartments are uninhabitable, written as actual loss sustained.
By the numbers
The lender floors, ownership rules, and coverage-form facts that surface when a cooperative corporation gets its blanket building policy quoted or a share-loan lender reviews the master policy.
- Fannie Mae co-op master-policy floor
- 100% replacement cost, deductible ≤ $50,000
- Co-op legal structure
- Corporation owns building; shareholders hold proprietary leases
- Mortgagee interest on the master policy
- ACORD 28 + lender's loss payable clause
- Ordinance-or-law structure
- Coverage A, B, and C
- Business income for co-ops
- Loss of maintenance / common charges
For a conforming share loan, Fannie Mae requires the master policy to insure 100% of the project improvements' replacement cost and settle on a replacement-cost basis. Lender Letter LL-2026-03, effective July 1, 2026, caps the single-occurrence deductible at $50,000 per unit.
In a housing cooperative the corporation owns the entire building and land, and residents buy shares carrying a proprietary lease rather than a deed. This is why the corporation insures the whole structure on a blanket policy instead of dividing it with owner HO-6s.
A lender on the underlying mortgage receives an ACORD 28 with coverage extended as mortgagee and lender's loss payee. Under the standard loss-payable clause the lender's recovery is protected even against exclusions the insurer could raise against the insured.
Ordinance-or-law coverage is written in three parts: Coverage A pays for loss to the undamaged portion a code officer condemns, Coverage B pays demolition, and Coverage C pays the increased cost of rebuilding to current code.
A well-built co-op property form includes business income covering the loss of monthly maintenance or common charges, not rent, so the corporation's operating revenue is replaced while apartments are uninhabitable, funding the mortgage and taxes during restoration.
Common questions
about commercial property for hoa insurance
It comes down to ownership. In a condominium each owner holds a deed, so the master policy divides the building against each owner's HO-6, and the bare-walls, single-entity, or all-in choice sets where the master stops. A cooperative has no such split: the corporation owns the whole building and shareholders hold proprietary leases, so it insures the entire structure, apartment interiors included, on one blanket limit. The HO-6 still carries furnishings and personal liability.
Because the corporation owns the building as a single asset, not a stack of separately deeded units. A blanket limit insures the whole structure under one shared amount rather than a fixed limit per apartment. At a near-total loss a scheduled per-unit policy strands coverage on undamaged apartments while leaving damaged ones short, whereas a blanket limit applies wherever the loss lands. It also mirrors the underlying mortgage, a blanket lien on the building.
Most cooperatives carry a blanket underlying mortgage on the building, repaid through shareholder maintenance. That senior lender imposes commercial-mortgagee terms: the master policy must insure 100% of replacement cost, settle on a replacement-cost basis, and name the lender as mortgagee and lender's loss payee. Banks financing individual apartments through share loans add their own loss-payee interest, so the certificate satisfies debt at two levels. A valuation gap or lapsed mortgagee clause can block the refinance.
Yes for the interior itself, no for the shareholder's furnishings or improvements. Because the corporation holds title, the blanket policy insures the apartment's original walls, floors, and built-in elements, broader than a bare-walls condo master. It does not reach personal property, installed betterments, or personal liability; those belong on the shareholder's HO-6. Most proprietary leases require that HO-6, and boards increasingly enforce it, since a shareholder without one has no coverage for contents.
Because their pre-war construction, wiring, plumbing, and layouts no longer meet current code. The base property limit rebuilds only to the code the building was originally built under. But a code officer often requires the repaired sections, and sometimes undamaged ones, brought up to current electrical, fire, accessibility, and structural code, or demolished as non-conforming. That cost hits reserves unless ordinance-or-law limits are bought high enough, so older cooperatives raise all three coverages above the grant.
It is the business income grant, written for how a cooperative earns money. A commercial version replaces lost rent; a co-op collects maintenance, so this replaces the maintenance the corporation loses when apartments are uninhabitable during a rebuild. That is operating revenue, not an owner assessment. Maintenance funds the underlying mortgage, real-estate taxes, live-in payroll, and operating costs. Written as actual loss sustained over the period of restoration, it keeps the corporation solvent without special-assessing shareholders.
