A co-op association in Idaho has to satisfy two things at once: the coverage architecture specific to co-op communities, and Idaho's own statutory and lender-warrantability requirements.
The corporation owns the entire building under one blanket policy, and coverage is built around the proprietary lease rather than around individually owned real-property units.

Idaho Co-op Insurance
A co-op community in Idaho sits at the intersection of two coverage questions. The first is structural to the association type: the corporation owns the entire building under one blanket policy, and coverage is built around the proprietary lease rather than around individually owned real-property units. The second is jurisdictional: Idaho's statute, its lender-warrantability climate, and its market conditions shape how that program has to be sized, documented, and placed. This page covers both, and how they meet.
The coverage architecture
What drives a co-op master policy
A cooperative's insurance architecture starts from a legal structure that looks similar to a condo on the surface but is fundamentally different underneath: the co-op corporation owns the building and the land outright, and shareholders hold shares in the corporation plus a proprietary lease granting occupancy of a specific unit, rather than owning real property directly. That means there is no equivalent to a condo's bare-walls-versus-all-in valuation-basis question, because there is only one owner of the physical structure. The corporation's master property policy is a single blanket placement covering the entire building, and it is written to full replacement cost the same way a condo master policy is, but with no unit-boundary allocation problem to solve.
The proprietary lease is the document that does the allocation work a condo declaration does: it typically defines what the corporation is responsible for maintaining and insuring (the building structure and systems) versus what falls to the shareholder (interior finishes, fixtures, and improvements within the unit), and shareholders carry their own policy, sometimes called an HO-6 equivalent or a co-op unit-owner's policy, to cover that interior piece plus their personal property and liability. Because the corporation, not each shareholder, is the sole named insured on the building, a shareholder's ability to get her own interior coverage placed correctly depends on the proprietary lease language, and mismatches between what the lease assigns and what the master policy actually covers create the same kind of claim-time surprise a condo valuation-basis mismatch does.
Directors and officers liability protects the co-op board in a structure economically similar to a condo board but with sharper edges: the corporation's board makes decisions that affect shareholder equity directly (approving or denying share transfers, setting maintenance charges, enforcing proprietary lease terms), which generates a distinct flavor of governance dispute. A fidelity or crime bond covering the corporation's funds, maintenance charges, and reserves rounds out the program, sized the same way as any association's, against reserves on hand plus a set period of assessments or maintenance charges.
•Blanket master property policy covering the entire building under a single corporate ownership structure
•Allocation of responsibility between the corporation and the shareholder as defined by the proprietary lease, not a declaration
•Directors and officers liability for board decisions on share transfers, maintenance charges, and proprietary lease enforcement
•Fidelity/crime bond covering the corporation's maintenance-charge receipts and reserves
•Shareholder interior/unit coverage gaps where the proprietary lease and the master policy do not align on responsibility
•General liability for common areas and corporate operations across the entire building
Idaho statutory backdrop
How Idaho law shapes the program
Idaho did not adopt the Uniform Common Interest Ownership Act, and its Condominium Property Act, at Idaho Code Title 55, Chapter 15, sets no specific property-insurance percentage. Idaho Code 55-1517 gives the management body an insurable interest and the authority to insure the project against fire and other casualty, but only if required by the declaration, the bylaws, or a mortgagee. The Act enables coverage rather than mandating a replacement-cost floor, and the contents-of-bylaws section at Idaho Code 55-1507 does not add one.
Because there is no statutory backstop, the governing documents and the lender standard are the real bar. A conventional loan sold to Fannie Mae requires master coverage at one hundred percent replacement cost under the Selling Guide, section B7-3, and many Idaho declarations independently require replacement-cost coverage. So while Idaho law itself sets no percentage, an Idaho condominium still has to meet the lender's replacement-cost standard to stay warrantable, which makes the valuation basis the decision that matters.
The Idaho Homeowners Association Act, at Title 55, Chapter 32, governs planned communities and is likewise silent on a specific insurance floor, leaving the declaration and lender requirements to control for single-family and townhome associations as well. Treat the declaration's insurance article as the operative standard and confirm it is actually met, since no state minimum will fill a gap.

How is co-op insurance different from condo insurance?
In a cooperative, the corporation owns the entire building and the land outright, and shareholders hold shares plus a proprietary lease granting occupancy of a unit, rather than owning individual real property. That means there is a single blanket master property policy on the whole building instead of a condo's bare-walls-versus-all-in valuation-basis question, and the proprietary lease, not a recorded declaration, is the document that allocates maintenance and insurance responsibility between the corporation and the shareholder.
Does a co-op shareholder need their own insurance policy if the corporation insures the whole building?
Yes. The corporation's blanket policy covers the building structure and systems, but the proprietary lease typically leaves interior finishes, fixtures, personal property, and personal liability to the shareholder. A shareholder's own policy needs to be scoped against what the proprietary lease actually assigns to them, since a mismatch between the lease language and the shareholder's policy is the same kind of gap a condo owner faces when their HO-6 does not match the master policy's valuation basis.
