A co-op association in MA has to satisfy two things at once: the coverage architecture specific to co-op communities, and MA'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.

MA Co-op Insurance
A co-op community in MA 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: MA'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
MA statutory backdrop
How MA law shapes the program
The Massachusetts condominium statute is General Laws Chapter 183A. Section 10 authorizes the organization of unit owners to obtain insurance on the common areas and facilities, written in the organization's name and without prejudice to each owner's right to insure the unit, but it does not set a specific replacement-cost percentage the way the 80 percent-floor states or the full-replacement-cost states do. In Massachusetts there is no statutory property-insurance floor. The master deed and bylaws, together with the lender's requirements, set the property standard, not the statute.
Chapter 183A does prescribe a fidelity requirement. For a condominium with more than ten units, Section 10 requires the organization to maintain blanket fidelity coverage against the dishonest acts of any person responsible for handling association funds, in an amount equal to at least one-fourth of the annual assessments, excluding special assessments, written in the organization's name and with advance written notice of cancellation or material change. That one-fourth figure is an exact statutory floor, and it should be recomputed each year as the budget and assessments change.
Because Chapter 183A is a condominium statute with no property percentage, and because Massachusetts has no separate planned-community act to fall back on, size the master property program to full replacement cost and the Fannie Mae Selling Guide warrantability bar rather than to a statutory minimum that does not exist here. Confirm the master policy is actually written to full replacement cost, since nothing in the statute forces that result on its own.

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.
