Condo Master Policy Deductible Calculator
Calculate how a condo association or HOA master policy deductible will be divided among unit owners after a hurricane, named storm, or other covered loss. This free deductible allocation tool shows the per-unit assessment amount, flags the gap between what a typical HO-6 loss assessment rider covers and what each owner will actually owe, and helps boards and unit owners plan before the next storm.

How Condo Master Policy Deductibles Work in Florida
Every Florida condominium association is required under Fla. Stat. §718.111(11) to carry a master insurance policy on all common elements, including the building structure, roof, exterior walls, and shared systems. That master policy almost always carries a separate, percentage-based hurricane or named-storm deductible — typically 2%, 3%, 5%, or 10% of the total Coverage A building value. For a $20 million building with a 5% hurricane deductible, that is a $1 million out-of-pocket cost to the association before insurance pays a dime.
The association cannot absorb that deductible on its own unless reserves are extraordinarily well funded. So the cost is passed through to unit owners as a special assessment. How that assessment is divided depends on the Declaration of Condominium — most Florida documents allocate by percentage of common element ownership (usually based on unit square footage), though some older buildings still allocate equally per unit. The gap between the assessment and what a unit owner's HO-6 loss assessment rider will pay is the single biggest financial surprise condo owners face after a hurricane.
What Is Loss Assessment Coverage and Why Is $2,000 Not Enough?
Loss assessment coverage is a rider on your individual HO-6 (unit owner) policy that reimburses you when the association levies a special assessment tied to a covered property or liability loss. Standard HO-6 policies often include only the statutory minimum — $2,000 in Florida. That was adequate when master policies carried small, flat-dollar deductibles. In the current Florida market, where percentage-based deductibles routinely produce $10,000-$25,000 per-unit assessments after a hurricane, $2,000 of coverage leaves most of the bill on the owner.
Most Florida insurance professionals now recommend $25,000 to $100,000 in loss assessment coverage for condo unit owners — the exact amount depending on your building's size, the master policy's deductible, and the association's reserve levels. The additional premium is typically small (often just a few dollars per month) relative to the protection. Review your HO-6 declarations page alongside the association's master policy declarations page to see the actual gap. For help disputing an underpaid claim or challenging how a special assessment was calculated, contact a Florida condo and HOA claims specialist.
Four Things Condo Boards and Unit Owners Miss on Master Policy Deductibles
The allocation method is set in the Declaration
The board does not choose how to split a special assessment — the Declaration of Condominium does. Most Florida declarations specify allocation by percentage of common element ownership, which is usually pegged to unit square footage. Larger units pay a larger share. Trying to impose equal-share allocation when the Declaration calls for proportional allocation (or vice versa) can trigger a unit owner challenge.
Named storm deductibles are different from hurricane deductibles
A named storm deductible can trigger when the National Hurricane Center names a tropical system — even if it never reaches hurricane strength. Hurricane deductibles only trigger when the storm is actually declared a hurricane. Many Florida condo master policies (especially in the surplus lines market) carry the broader named-storm language, which catches more losses than owners expect.
The deductible applies to the full Coverage A, not the damage
A 5% deductible on a $20 million building is $1 million — regardless of whether the damage is $1.5 million or $15 million. That calculation does not scale with the loss. On smaller covered claims, the deductible can exceed the damage entirely, leaving the association to cover everything and still have no payout from the carrier.
Reserves can be used — if the board votes
Florida's post-Surfside reforms (Fla. Stat. §718.112) require structural reserves that boards cannot waive. But operating reserves, if well funded, can sometimes absorb a portion of a hurricane deductible — reducing the per-unit special assessment. This requires a properly noticed board meeting, a majority vote, and careful documentation so unit owners don't later challenge the decision.
Condo Master Policy Deductible Calculator FAQs
A condo master policy hurricane or named-storm deductible is calculated as a percentage of the association's Coverage A (building replacement value) — typically 2%, 3%, 5%, or 10% in Florida. The percentage is applied against the total insured value, not against the damage amount. A 5% deductible on a $30 million building is $1.5 million, whether the damage is $2 million or $20 million. That amount is then divided among unit owners through a special assessment, using the allocation method specified in the Declaration of Condominium.
Florida law (§718.111) requires special assessments to be allocated according to the Declaration of Condominium. Most Florida declarations specify allocation by percentage of common element ownership — usually based on the unit's under-air square footage relative to the total building square footage. Some older declarations allocate equally per unit regardless of size. Check your Declaration's allocation schedule before relying on any assumption. HOAs (as opposed to condos) operate under Chapter 720, which provides broader board discretion on allocation methods.
Loss assessment coverage is a rider on your individual HO-6 (condo unit owner) policy that reimburses you when the association levies a special assessment tied to a covered property or liability loss. Standard HO-6 policies in Florida often include only the $2,000 statutory minimum, which is insufficient for most modern master policy deductibles. Florida insurance professionals commonly recommend $25,000 to $100,000 in loss assessment coverage for condo owners, depending on building size and the master policy's deductible structure.
Operating reserves can sometimes be used to absorb a portion of a master policy deductible, reducing the per-unit special assessment. This requires a properly noticed board meeting, a majority vote, and compliance with Florida's post-Surfside reserve laws. Structural reserves (required under §718.112 for buildings with milestone inspection obligations) cannot be used for non-structural purposes. If the board is considering using reserves to soften a special assessment, consult counsel before voting — an improper reserve use can be challenged and reversed.
Unit owners can challenge special assessments on several grounds: the board did not follow proper notice procedures, the allocation method does not match the Declaration, the deductible was miscalculated, or the association's master policy claim was underpaid (which would have reduced the gap the assessment is trying to fill). If the assessment is tied to a claim the carrier underpaid, the most effective path is often to push back on the carrier — a successful claim dispute can reduce or eliminate the assessment entirely. A licensed public adjuster can review the master policy claim for this purpose.
Yes, with one important difference. Condo associations operate under Chapter 718 and are required to carry a master property policy on the building. HOAs operate under Chapter 720 and typically only insure common amenities (clubhouse, pool house, entry monuments) — each homeowner insures their own house. The allocation math in this tool works for both structures, but the per-unit assessment on an HOA master policy deductible is usually much smaller because the insured value is limited to common elements rather than entire residences.
The board can negotiate with the carrier at renewal to request a lower hurricane deductible (e.g. moving from 5% to 3%), though this comes with a higher annual premium. Wind mitigation improvements — roof upgrades, impact windows, hurricane straps — can qualify the association for premium credits that offset the cost of a lower deductible. A wind mitigation inspection every few years often reveals credits the carrier has not applied. Loss history, claims experience, and building age all factor into what deductible options the market will offer at renewal.

This Condo Master Policy Deductible Calculator is provided by Shoreline Public Adjusters, LLC for general informational and educational purposes only. The allocation calculations shown are illustrative examples based on common Florida condominium master policy deductible structures (2%, 3%, 5%, or 10% of Coverage A) and the two most common allocation methods (equal-per-unit or by-square-footage). Actual special assessments depend on the specific language in your Declaration of Condominium, bylaws, master policy terms, and applicable Florida statutes.
Shoreline Public Adjusters makes no warranties or guarantees, express or implied, regarding the accuracy, completeness, or applicability of any calculation or information on this page. Your actual per-unit assessment may differ based on the Declaration's allocation schedule, association reserves applied to the loss, the carrier's final payout, amendments to the Declaration, side agreements, non-standard allocation provisions for commercial units or limited common elements, and other factors this tool cannot account for. The loss assessment coverage gap shown is also an estimate — your HO-6 policy may contain sub-limits, exclusions, or allocation rules that alter the actual reimbursement.
This calculator does not constitute legal advice, insurance advice, or a binding evaluation of any claim or assessment. Nothing on this page creates an adjuster-client, attorney-client, or association-client relationship.
