A condo association master insurance policy is the association-level policy that covers the building structure, shared systems, and common areas of the community, along with the association's liability. The policy form your association chooses (bare walls, single entity, or all-in) sets the line between where the association's coverage ends and each unit owner's coverage begins.
For boards and the brokers who serve them, the master policy is the financial backbone of the community. The practical question is rarely "are we insured?" but rather "are we insured for the loss we are actually worried about?" That question gets sharpest around catastrophe perils like wind and flood, where sublimits, deductibles, and slow claims can leave real gaps even when the policy technically responds. A growing number of associations close those gaps with a parametric layer – coverage that pays a predefined amount based on the measured intensity of an event rather than a line-by-line damage assessment.
This guide explains what the master policy covers, the main policy types, what shapes the coverage you get, and where parametric protection helps when a large event arrives.
What is a condo association master insurance policy?
The master policy insures the property the association owns collectively: the building structure, the roof, shared mechanical systems, and common areas such as lobbies, hallways, elevators, and amenities. It also carries the association's liability coverage for incidents that happen in those shared spaces.
It supplements rather than replaces the policies individual owners carry on their units. Think of the master policy as covering the shell and the shared spaces, while owners insure the inside of their own homes and their belongings. Your broker places and structures this coverage, and is the right first call whenever the building, occupancy, or shared amenities change.
What does a condo association master policy cover?
The master policy covers the building and shared property; individual unit interiors and owner belongings sit with the unit owner. The exact dividing line depends on the policy form, but the broad split looks like this:
Typically covered by the master policy | Typically the unit owner's responsibility |
The building structure and roof | Personal belongings inside the unit |
Shared and common elements (lobbies, hallways, elevators, pools) | Interior improvements and upgrades (depending on the form) |
Common-area liability (someone injured in a shared space) | Personal liability inside the unit |
Shared mechanical systems and equipment | Loss assessment exposure passed to owners |
The headline coverage is usually solid for everyday events: a burst pipe in a hallway, a fire in a shared mechanical room, a slip-and-fall claim in the lobby. Where boards get caught out is the large, infrequent event, and that is where reading past the coverage summary matters.
What are the main types of master policy?
The three common forms differ in how far the association's coverage reaches into each unit:
Policy form | What the association covers | What the owner typically covers |
Bare walls-in | Structure up to the unfinished interior surfaces | Fixtures, finishes, improvements, and belongings |
Single entity | Structure plus original fixtures and standard finishes | Upgrades, improvements, and belongings |
All-in (all-inclusive) | Structure, fixtures, and built-in features inside the unit | Personal belongings and certain improvements |
The form matters because it determines who repairs what after a loss. A community on a bare walls form pushes more responsibility to owners; an all-in form keeps more with the association. Confirming which form is in place is one of the most useful things a board can do with its broker, because residents often assume more is covered than actually is.
What determines how much a master policy covers?
Three factors shape the scope and adequacy of the coverage:
- The building itself. Construction type, age, roof condition, and any resilience features influence how a property is expected to perform in a major event. Two buildings with identical values can carry very different real-world exposure based on how they are built.
- Location and exposure. A coastal building and an inland one face different natural-event profiles, and the master policy structure usually reflects that through its catastrophe terms.
- The policy form and limits chosen. The form sets the breadth of coverage, while sublimits and deductibles set how far it stretches for specific perils.
The headline limit rarely tells the whole story. The catastrophe sublimits and deductibles sitting inside the policy are what determine how the program behaves under stress.
What is usually not covered, or only partly covered?
Most master policies respond well to routine losses, however the remaining exposure tends to concentrate in:
- Catastrophe sublimits for wind. Coverage for windstorm is often capped well below the building's full value through a sublimit. The policy responds, but only up to that capped amount, leaving the association to fund the rest.
- Flood and storm surge, treated separately from wind. Flood is usually handled on different terms than wind in a master policy. It is either excluded outright or written under its own, often modest, sublimit. For coastal communities, storm surge can be the single largest source of hurricane-related loss, which makes it the peril boards are most likely to be under-protected against, even when the wind coverage looks solid.
- Wildfire, especially in high-severity zones. Associations in high-severity wildfire areas increasingly find admitted carriers unwilling to renew coverage at all, pushing them into a state residual market such as the California FAIR Plan. Those residual markets typically insure the structure only, up to a set per-structure and per-association cap, and exclude landscaping, shared amenities, evacuation costs, and private firefighter fees, leaving associations to fund the community-facing part of a wildfire loss themselves.
- The association's deductible. After a major event, the association pays the deductible before any payment flows. For catastrophe perils this can be a percentage of insured value, which translates into a significant out-of-pocket sum the reserve fund has to absorb.
- Speed and cash flow. Even when a claim is fully covered, traditional loss adjustment can take months. An association still has to keep the lights on, pay vendors, and reassure residents while it waits.
None of this means the master policy is doing its job poorly. It means the policy is built for breadth, and the catastrophe tail is where a board's real financial volatility lives.
How can an association close those gaps?
A growing number of associations add a parametric layer on top of the master policy. Parametric insurance pays a predefined amount based on the measured intensity of an event (for example, a wind speed or a modeled water elevation at the property), rather than on a line-by-line assessment of damage.
For a condo board, that translates into things the master policy struggles to deliver:
Restored protection above a sublimit
A parametric layer can be structured to respond when a catastrophe sublimit is exhausted, helping bring total protection back in line with the building's actual exposure.
Liquidity for the deductible
Instead of absorbing a large first loss from reserves, the association can receive a trigger-based payout to cover the deductible and immediate costs.
Dedicated flood and storm surge protection
Because flood sits outside, or on much thinner terms than, the wind coverage in most master policies, a parametric storm surge layer can be sized specifically to close that gap for coastal buildings, paying out based on modeled peak water elevation at the property. Depending on the building and the storm, a parametric named-windstorm layer can sometimes cover flood-driven losses too since its trigger is the storm's track and intensity rather than the peril that caused the damage, so whether a community needs one combined layer or two separate ones is a sizing question best worked out with a broker, not a default assumption either way.
Wildfire protection built around a satellite trigger
A parametric wildfire layer pays out when a wildfire breaches a predefined perimeter around the property, typically 100 meters, verified using satellite imagery rather than an on-site adjuster. It can be used to buy down a residual-market deductible, or to fund the landscaping, shared amenities, evacuation costs, and private firefighter fees that a program like the California FAIR Plan leaves out entirely.
Smaller, more predictable special assessments
When a shortfall lands on the association, boards typically close it with a special assessment, a one-time bill unit owners have to pay on short notice, often on top of an already stressful event. Over 60% of HOAs report issuing at least one special assessment per year. A parametric payout that fills the sublimit gap, funds the deductible, or covers an excluded peril reduces the amount the board needs to raise from owners, and in some cases removes the need for a special assessment altogether.
Speed and transparency
Because the trigger and the payout are defined and agreed in advance, there is no drawn-out adjustment, and funds can arrive within days to weeks of an event, exactly when an association needs cash to act.
Each layer is structured around the community's specific building, exposure, and budget, so it complements the master policy rather than duplicating it. The point is not to replace the master policy; it is to make sure the program holds together when a large event, wind, flood, or wildfire, tests it.
How Descartes works with your broker
Descartes Underwriting designs parametric coverage that complements an association's existing master policy. We work through your broker, who keeps the client relationship and remains your single point of contact, while we focus on structuring a layer that fits the building, the exposure, and the budget.
What that looks like in practice:
- Built around your community. Rather than an off-the-shelf product, the layer is shaped to the specific building and the gap you are trying to close, whether that is a catastrophe sublimit, a deductible, or the need for fast cash after an event.
- Designed to track real exposure. We use detailed data and modeling so the payout is designed to correspond as closely as possible to how a given building is actually affected by an event, which keeps the coverage relevant and the terms transparent.
- Fast, predefined payouts. Because the trigger and payout are agreed up front, there is no loss-adjustment process to wait through, and funds can reach the association within days to weeks.
- A partner to the broker. The aim is to make it easy for your broker to bring the association a solution to a problem the standard program leaves open, with the technical work handled on our side.
Descartes was founded in 2019 with a focus on protecting organizations against climate and catastrophe risk, and works with corporate brokers globally. For an association, the relevant point is simpler: a complementary layer that is transparent, quick to pay, and built specifically for the gap in your program.
Illustrative examples
The following are simplified scenarios with hypothetical figures, used only to show the mechanics. They do not describe specific communities, actual policies, or real claim outcomes.
Example 1: A board that needs cash quickly after an event
- The setup: The program is a tower: the master policy covers the underlying repair, and a smaller parametric layer sits alongside it to fund the deductible and interim costs the master policy won't advance until the claim settles.
- The event: A storm damages the lobby and elevators, and residents expect them back in service within days.
- The gap: The master policy will pay eventually, but adjustment can take months. The deductible and interim costs (temporary equipment, expedited vendor fees) still need funding now.
- The parametric response: Sized to the deductible and interim costs, not the repair itself, the parametric payout arrives in about two to three weeks.
Example 2: A coastal community hit by storm surge
- The setup: The master policy either excludes flood or caps it at $2 million, well below what a major surge event can cause to ground-floor space and mechanical systems.
- The event: A hurricane pushes an 8-foot storm surge into the property, similar in scale to the flooding Hurricane Ian drove into low-lying Florida coastal communities in 2022.
- The gap: Flood-related damage, debris removal, and lost revenue exceed the master policy's flood sublimit, or are not covered at all, because flood sits outside the wind terms.
- The parametric response: A storm surge layer tied to peak water elevation at the property pays out once a threshold is reached, funding cleanup, mechanical repairs, and lost revenue without a lengthy adjustment.
Example 3: An association pushed into a wildfire residual market
- The setup: After repeated non-renewals, the association's coverage moves to a state residual market such as the California FAIR Plan, which insures the structure only, up to a $20 million per-structure and $100 million per-association cap, and excludes landscaping, shared amenities, evacuation costs, and private firefighter fees.
- The event: A wildfire breaches the community's perimeter, damaging the clubhouse grounds and forcing a multi-day evacuation.
- The gap: The residual market policy responds to the structural damage, but the landscaping, shared amenities, and evacuation costs fall entirely outside it, and the claim itself can take months to settle.
- The parametric response: A wildfire layer triggers once the fire crosses a 100-meter perimeter around the property, confirmed by satellite imagery, and pays out within weeks, funding landscaping repairs, evacuation costs, and private firefighter fees without waiting on the residual-market claim.
Example 4: A coastal community with a capped wind sublimit
- The setup: The master policy caps named-storm coverage at a $10 million sublimit, roughly 25% of the building's value.
- The event: A severe storm produces about $18 million of wind damage.
- The gap: The master policy pays up to its $10 million sublimit, leaving an $8 million shortfall the association would otherwise fund itself.
- The parametric response: A wind layer sized near the $8 million gap, set to respond once a defined wind speed is reached at the property, closes the shortfall and brings total protection back toward the building's true exposure.
Frequently asked questions
How much insurance should a condo association carry?
Enough to rebuild the property at current replacement cost and to absorb the deductible and any catastrophe gap, wind or flood, without destabilizing the reserve fund. The right figure depends on the building and its exposure, so it is best confirmed with a broker who knows the community.
Does the master policy cover individual units? Generally, no. The master policy covers the building and shared areas; coverage for the inside of a unit and an owner's belongings usually comes from a separate unit-owner policy. Where the line falls depends on the policy form (see above).
Who is responsible for the deductible after a claim?
The association pays the master policy deductible. In many communities, governing documents allow part of that cost to be passed to unit owners through a loss assessment, which is why owners are often encouraged to carry loss assessment coverage.
How often should an association review its master policy?
At least annually, and any time the building value, occupancy, or shared amenities change materially, also the right moment to check whether catastrophe sublimits and deductibles still match the building's exposure.
Can a small association benefit from a parametric layer?
Yes. Because parametric structures are built around a specific budget and exposure, they can be sized for smaller communities as well as large ones. The starting point is the size of the catastrophe gap, not the size of the association.
How do I get a quote?
Coverage is placed through a broker, who markets the association's needs and can present both the master policy and complementary layers such as parametric wind and storm surge cover. Have the building's replacement value, construction type, and current program details ready, so the quote reflects the community's real exposure rather than a generic estimate.
What does a condo association parametric insurance policy include?
Three elements: a defined trigger (e.g., a wind speed or modeled water elevation measured at or near the property), a predefined payout tied to that trigger, and terms agreed up front so there is no loss adjustment after an event. It sits alongside the master policy, sized to the building's exposure and budget, and designed to pay quickly once the trigger is met.
What perils can Descartes cover?
Beyond the wind, flood, and storm surge coverage this guide focuses on, Descartes structures parametric layers across the full range of catastrophe perils real estate assets face, including hurricanes and tropical cyclones, flood (pluvial, fluvial, and storm surge), wildfire, earthquake, and severe convective storms such as hail and tornadoes. An association's program can combine layers across more than one of these perils depending on its exposure.
