Condo Insurance in Massachusetts, What HO-6 Covers and What the Master Policy Doesn't

Massachusetts has a huge condominium market, converted triple-deckers across Boston, Somerville, and Cambridge; new mid-rises in the Seaport and the Gateway Cities; suburban townhouse associations everywhere. Condo owners often assume the association's master policy covers them. It doesn't, not fully. The gap between the master policy and your personal HO-6 policy is where expensive surprises live. Here's how Massachusetts condo insurance actually works.

Two policies, two jobs

A Massachusetts condo is covered by two separate insurance policies:

1. The association master policy, paid for through your condo fees, covers the building structure and common areas.
2. Your personal HO-6 policy, that you buy individually, covers your unit's interior, your belongings, your liability, and the gaps the master policy leaves.

The critical question is where the master policy stops and your HO-6 starts, and that line is defined by your condo's master deed and bylaws, not by a universal rule.

The three master-policy types (read your bylaws)

Massachusetts condo master policies come in three flavors, and which one your association has determines how much your HO-6 must cover:

"All-in" (or "all-inclusive")

The master policy covers the unit including fixtures, built-ins, and often the original finishes (cabinets, flooring, etc.) as originally built. Your HO-6 covers your belongings, upgrades/improvements, liability, and loss assessment. Smallest HO-6 needed.

"Bare walls" (or "studs-in")

The master policy covers the structure only, the framing, exterior, roof, common areas, and stops at the bare studs. Everything inside the drywall surface is yours to insure: drywall, flooring, cabinets, fixtures, appliances, the works. Largest HO-6 needed, your dwelling coverage (Coverage A) has to rebuild the entire interior.

"Single entity" / "original specs"

A middle ground, the master covers the unit as originally built, but your upgrades and improvements are yours. Common in MA.

You cannot size your HO-6 correctly without knowing which type your association has. Get the master deed and the master policy's certificate of insurance, and have your agent read them.

What your HO-6 must cover

A properly-built Massachusetts HO-6 includes:

• Coverage A, Dwelling (walls-in): rebuilds your unit's interior to the extent the master policy doesn't. On a bare-walls association, this needs to be substantial, enough to redo drywall, floors, kitchen, baths. Under-insuring here is the most common MA condo mistake.
• Coverage C, Personal property: your belongings.
• Coverage E, Personal liability: if someone's injured in your unit, or you cause damage to a neighbor's unit (a common condo claim, your overflowing tub damages the unit below).
• Loss of use: living expenses if your unit is uninhabitable after a covered loss.
• Loss assessment coverage: this one is MA-condo-critical (see below).

Loss assessment, the coverage condo owners forget

When a loss exceeds the master policy's limits, or hits the master policy's deductible, the association can assess every unit owner their share. Examples:

• The building's roof is destroyed and the master policy's payout falls short → owners are assessed the difference.
• The master policy has a $25,000 deductible (common on MA condo master policies, and rising) and a covered loss occurs → that deductible gets assessed across the owners, or charged to the unit where the loss originated.

Loss assessment coverage on your HO-6 pays your share of these assessments. Given that MA condo master-policy deductibles have been climbing (some now $25,000-$50,000+), adequate loss-assessment coverage is essential , and the base limit on many HO-6 policies ($1,000-$5,000) is far too low. Many MA condo owners should carry $25,000-$50,000 in loss assessment to match their association's master deductible.

The master-deductible "gap", a growing MA problem

As master-policy deductibles rise, a specific gap has opened: if a covered loss originates in your unit (say, a burst pipe), the association may charge you the entire master-policy deductible, which could be $25,000+. Your HO-6's loss-assessment coverage (and sometimes a specific "master policy deductible" endorsement) is what protects you. Ask your agent specifically: "If I cause a loss and the association charges me their $X deductible, am I covered?"

What it costs in Massachusetts

Condo type	Typical HO-6 annual premium
Suburban townhouse / mid-size unit	$400 – $900
Boston / Cambridge / Somerville urban condo	$500 – $1,200
Larger / higher-value unit	$1,000 – $2,000
Coastal condo (Revere, Quincy shore, Cape)	$1,200 – $3,500+

HO-6 is generally affordable, which makes under-coverage (especially on walls-in dwelling and loss assessment) a false economy. The premium difference between adequate and inadequate coverage is small; the exposure is large.

Flood, separate, and relevant for coastal MA condos

As everywhere, the master policy and your HO-6 exclude flood. Coastal Massachusetts condos (Revere Beach, Quincy shore, Winthrop, Cape, South Shore) in FEMA flood zones need flood coverage, sometimes the association carries a master flood policy, sometimes individual owners must. Confirm which, and whether it's adequate, for any coastal MA condo.

Five questions for your condo HO-6

1. "Is my association's master policy all-in, bare-walls, or single-entity?" , determines how much dwelling coverage I need.
2. "What's the master policy's deductible, and does my loss-assessment coverage match it?", the growing MA gap.
3. "If I cause a loss (burst pipe, overflow), what's my exposure to the master deductible?"
4. "Is my dwelling (walls-in) coverage enough to redo my interior on a bare-walls policy?"
5. "For a coastal unit, who carries flood, the association or me, and is it enough?"

The Massachusetts condo owner's biggest insurance risk isn't the premium , it's the assumption that the master policy has them covered. Read the master deed, match your HO-6 to its gaps, and carry loss-assessment coverage that matches the association's deductible. The coverage is cheap; the gap is not.
