What it means
Condominium ownership splits a building into two insurance puzzles: the association insures the common structure, and each owner insures a unit, but the line between the two must be drawn somewhere. Bare walls coverage draws it at the unfinished surface, as the master policy stops at the bare framing and drywall, and everything inward belongs to the owner's policy.
The practical effect surprises first-time buyers, since the association's policy will not pay for your kitchen cabinets, bathroom fittings, flooring, or sometimes even the plumbing and wiring inside your walls, all of which is yours to insure through your own condominium unit-owner policy, often called an HO-6. The alternative approaches draw the line elsewhere.
Some master policies cover the unit as originally built, including standard fixtures, and a few cover everything except the owner's personal belongings, with the scheme set by the association's governing documents, so two visually identical buildings can sit at opposite extremes. Consumer guidance from the National Association of Insurance Commissioners urges unit owners to read exactly this boundary before a loss, because the most common condominium insurance failure is each party assuming the other's policy reaches further than it does.
The gap appears only after the pipe bursts. For a buyer, the discovery process is concrete: ask the association for its master policy and the declaration defining what it covers, then instruct your own insurer to fill everything left out, including interior structure, improvements, personal property, and liability.
Loss assessment coverage matters in the same conversation, since when a claim exceeds the association's limits or falls to its deductible, the shortfall is often assessed against unit owners, and an HO-6 policy with loss assessment cover absorbs that shock. Renovations raise the stakes silently.
A previous owner's marble bathroom and custom kitchen live on your side of the bare walls line, and an HO-6 limit set to the original fit-out underinsures the upgraded one, so improvements should be revalued into the policy after every renovation. Landlords who rent out their units face a further layer, because the tenant's belongings are their own problem but the landlord-owner still carries the interior structure and should also carry landlord liability, as the bare walls boundary follows ownership, not occupancy.
For managers of associations, the choice of boundary is a pricing decision. Bare walls master policies are cheaper for the association but push cost and confusion onto owners, while fuller coverage raises dues but simplifies claims, and either works if, and only if, every owner knows which world they live in.
The concept generalises to any shared-ownership property, because wherever two policies meet, the seam is where uninsured losses hide, and the cheapest premium is no bargain if it buys a gap. The takeaway is one sentence long: find the line, insure your side of it, and put the answer in writing before the water comes through the ceiling.
In practice
Real-world examples.
Example
A buyer discovers the master policy stops at the drywall and raises her HO-6 structural limit accordingly. She asks her insurer to cover the interior structure and the kitchen she is about to renovate. The premium rises a little, but the gap closes.
Example
An association switches from bare walls to all-in coverage to simplify claims after repeated disputes. Dues rise slightly to pay for the broader master policy. Owners no longer argue over whether a damaged fitting is theirs or the association's.
Example
An owner adds loss assessment cover after the association's large deductible is charged back to units. The deductible after a burst pipe is shared across all owners. The extra cover turns a surprise bill into an insured loss.
Formula
Calculation
There is no formula as such; the insurance need is arithmetic: owner's required cover = rebuild cost of interior structure + value of improvements + personal property + liability, minus anything the master policy provably covers inside the unit.
Worked example. An owner estimates $40,000 to rebuild the unit's interior structure, $50,000 of improvements such as cabinets and flooring, and $25,000 of personal property. Under bare walls coverage the master policy covers none of these, so the required property cover is $40,000 + $50,000 + $25,000 = $115,000, with a separate liability limit on top. The interior fittings alone, $40,000 + $50,000 = $90,000, match the loss in the case study below.Case study
Seen in the real world.
Fictional example. A fire damages a condominium unit whose association carries bare walls coverage. The master policy rebuilds the shell, but the $90,000 of interior fittings, flooring, and cabinetry falls to the owner's HO-6 policy, which pays because the owner insured the interior at renovation value rather than purchase price. The neighbouring owner, who had assumed the association covered everything, discovers that the same fire left her with a bill for the interior and no policy to pay it. The association circulates a plain-language note to all owners, with the master policy attached, and several owners review their own cover that month.
Watch out
Common mistakes.
- Assuming the master policy covers the interior. Under bare walls coverage it stops at the unfinished wall surface, and cabinets, flooring, and in-wall systems are the owner's responsibility unless their own policy insures them.
- Underinsuring renovations. Upgrades made by any previous owner sit on the owner's side of the line, and an HO-6 limit based on the original fit-out leaves improvements uninsured.
- Forgetting loss assessment. Association deductibles and shortfalls are frequently assessed to unit owners, and without loss assessment cover that bill arrives as a personal surprise.
Questions
People also ask.
What is bare walls coverage?
It is a condominium master policy approach that covers the building only up to the bare interior surfaces of each unit, leaving interior fittings, improvements, and contents to the unit owner's own insurance.
What policy fills the gap?
The owner's condominium unit policy, commonly called HO-6, can cover interior structure, improvements, personal property, liability, and loss assessments from the association.
How do I know where the line is?
Ask the association for the master policy and governing documents; the definition of what the association covers inside a unit is written there and varies widely between buildings.
