Condo insurance confuses owners for a structural reason: the building is covered by two policies that meet at an invisible boundary, and almost every unpleasant surprise in condo claims comes from misunderstanding where that boundary sits. The association's MASTER POLICY insures the shared structure; your HO-6 — the condo owner's policy — insures inward from wherever the master policy stops, plus your belongings, your liability, and several protections specific to association life. This article covers the boundary, the HO-6's working parts, and the gaps that surprise Claremont owners. It deepens the condo and townhome guide and borrows the standing frame of the insurance guide: concept-level throughout, with your association's actual documents and your own agent governing the specifics — and in California's tightened market, the shop-when-escrow-opens rule applies to condos exactly as to houses.
The boundary: what the master policy actually covers
Master policies come in conceptual flavors, and the association's CC&Rs and policy documents say which one governs your building. The spectrum runs from BARE-WALLS coverage (the master policy insures the structure to the unfinished surfaces of your unit — everything inward, from drywall and flooring to cabinets and fixtures, is yours to insure) through ALL-IN or ORIGINAL-SPECIFICATION coverage (the master policy extends to the unit's interior finishes as originally built, leaving your upgrades and everything after to you). The difference is not academic: between bare-walls and all-in lies the entire interior of your home, and an HO-6 sized for the wrong assumption is either an expensive redundancy or — far worse — a five-figure gap discovered at claim time. The move is mechanical: get the master policy summary from the escrow package (the process guide lists it) or from the association, hand it to your insurance agent, and let the HO-6's dwelling coverage be built from what the master policy actually excludes rather than from a guess.
The HO-6's working parts
Beyond the interior-structure piece, the policy carries the familiar personal lines: PERSONAL PROPERTY (your belongings, ideally on replacement-cost terms); LIABILITY (which follows you, not just the unit); and LOSS OF USE (temporary housing while a covered claim makes the unit unlivable — worth a hard look in stacked buildings, where a neighbor's fire or water event can displace you through no event of your own). Then the two condo-specific coverages that do the most quiet work. LOSS ASSESSMENT COVERAGE: when the association suffers a covered loss that exceeds the master policy — or eats a master-policy deductible — it can assess the shortfall across owners, and loss assessment coverage answers that bill up to its limit; it is routinely cheap to increase, and the master policy's deductible size (rising sharply market-wide in recent years) is the number that tells you how much you want. MASTER-DEDUCTIBLE EXPOSURE generally: associations increasingly carry large water-damage deductibles specifically, and some CC&Rs push the deductible for a unit-originating claim onto that unit's owner — a sentence in the documents that decides whether a burst supply line costs you your HO-6 deductible or the association's much larger one. The water theme is no accident: water is the dominant condo claim, it travels through shared assemblies into neighboring units, and it is exactly why the leak-sensor guide's cheap protective layer earns its keep in stacked buildings especially.
The buyer's and owner's checklist
AT PURCHASE: read the master-policy summary and the CC&Rs' insurance and deductible-allocation sections before quoting; have your agent size dwelling coverage from the boundary and loss-assessment coverage from the master deductible; and confirm the lender's requirements, since condo loans expect both policies to be adequate. AS AN OWNER, RE-CHECK ON TWO TRIGGERS: when the association renews or changes its master policy (deductibles move, and your HO-6 should move with them — renewal summaries are worth actually reading), and when you renovate (upgrades beyond original specification are typically yours to insure regardless of master-policy flavor, and undocumented improvements are unclaimable improvements — keep the receipts in the house file). And the market note this cluster cannot skip: associations themselves face California's hardened insurance market, and a master policy that non-renews or jumps in cost lands on owners as dues increases or assessments — one more reason the association's insurance line-item belongs in the financial reading the reserves guide teaches. This is general information, not insurance advice; the CC&Rs, the current master policy, and your agent govern.

Frequently asked questions
What does an HO-6 condo policy cover?
Everything inward from where the association's master policy stops — interior structure per the boundary, personal property, liability, loss of use — plus the condo-specific pieces: loss assessment coverage for shortfalls the association bills across owners, and protection against master-policy deductible exposure. The master policy's actual terms decide how much dwelling coverage you need.
What is the difference between bare-walls and all-in master policies?
Bare-walls insures the structure only to your unit's unfinished surfaces — drywall, flooring, cabinets, and fixtures are yours to insure. All-in extends to interior finishes as originally built, leaving upgrades to you. The entire interior of your home lies between the two definitions, so the HO-6 must be sized from the association's documents, not a guess.
What is loss assessment coverage?
Coverage for your share when the association assesses owners for a covered loss exceeding the master policy — or for a master-policy deductible. With association deductibles rising sharply, especially for water, it is routinely the cheapest meaningful increase on an HO-6; size it from the master policy's current deductible.
Who pays when water from my unit damages the building?
It depends on the CC&Rs: some associations push the master-policy deductible for a unit-originating claim onto that unit's owner — a sentence that can turn a burst supply line into the association's large deductible on your bill. Read the deductible-allocation language, insure accordingly, and consider leak sensors; water is the dominant condo claim.
