Fannie Mae Condo Insurance Requirements: The 2026 Master Policy Rules Lenders Check

To pass a Fannie Mae project review in 2026, a condo or co-op needs a master property policy covering 100% of replacement cost value, general liability of at least $1 million per occurrence, and fidelity coverage for everyone who touches association money. This year the Fannie Mae condo insurance requirements added a hard ceiling: the master-policy per-unit deductible cannot exceed $50,000. That cap took effect July 1, 2026, and it is quietly forcing hundreds of associations to rewrite their master policies before their next buyer can get a loan.

This guide breaks down each policy Fannie checks, what changed under Lender Letter LL-2026-03, and what a board or manager has to fix before renewal. Fannie owns the rulebook but does not explain it in plain terms, so the job here is translating the pinpoint guide sections into the decisions that keep a project warrantable.

What insurance does Fannie Mae require for a condo?

Fannie Mae requires four coverages from a condo or co-op project: a master property policy at 100% replacement cost, general liability of at least $1 million per occurrence, fidelity/crime coverage sized to the association's funds, and flood insurance when the buildings sit in a Special Flood Hazard Area. Each requirement lives in Fannie's Selling Guide chapters B7-3 and B7-4.

The anchor is the master property policy, the HOA commercial property coverage that insures the buildings, roofs, and common elements as one unit. Fannie requires it to carry a Condominium Association Coverage Form (or its equivalent) and to cover at least 100% of the project improvements' replacement cost, per Fannie Mae's B7-3-03. That form also has to recognize an insurance trustee, waive the carrier's right to recover from unit owners, and treat unit-owner insurance as primary. One quirk from the 2026 update: inflation guard is no longer required.

The liability line is the one boards underestimate. Fannie's B7-4-01 sets a floor of $1 million per occurrence, expects the policy to name the association as the insured with premiums paid as a common expense, and requires a severability of interests provision so one unit owner's negligence cannot void another owner's claim.

Fannie's $50,000 master deductible cap explained

For loan applications dated on or after July 1, 2026, Fannie Mae caps the per-unit deductible on a condo master property policy at $50,000 for all required perils. Lender Letter LL-2026-03 set that flat dollar limit and retired the older rule, which had allowed a deductible of up to 5% of the policy's face value. On a $30 million building, the old 5% math could push the deductible toward $1.5 million.

The change answers a hard property-insurance market. As carriers raised deductibles to hold premiums down, more condo master policies drifted past what Fannie would accept, and those projects quietly turned non-warrantable. A flat $50,000 ceiling gives a board one number to hold its carrier to, no matter what the building is worth.

A 90-unit condo: the old rule versus the new cap

Take a 90-unit condo with buildings valued at $24 million and a master policy that last renewed with a 5% deductible. Under the old rule, that deductible was $1.2 million, applied to whichever units a loss touched. The 2026 rule ignores the percentage entirely: anything over the flat $50,000 cap fails the project review, so a $1.2 million deductible blocks financing for all 90 units.

To stay warrantable, the board has to bring the per-unit deductible down to $50,000 or less, which usually means a higher premium or a restructured policy. At the same time, each owner's HO-6 has to absorb a $50,000 deductible share instead of the old $2,000 loss assessment default. It is the same building and the same carrier, but two numbers now have to move together.

Single-entity vs bare-walls: what the master policy must cover

Fannie expects the master property policy to insure the unit interiors to their original condition, unless the association's recorded documents assign that job to the unit owners. The industry has two names for the split: an all-in or single-entity policy covers the interiors and fixtures, while a bare-walls or studs-out policy stops at the unfinished surfaces and leaves cabinets, flooring, and built-ins to the owner.

The coverage structure decides how large the HO-6 has to be. Under a bare-walls master policy, the owner's HO-6 carries the entire interior, so a thin unit-owner policy leaves a real hole. Under an all-in policy, the HO-6 mostly fills the deductible and personal property. Reading the master policy's coverage form is the only way to know which one a building runs, and it is not always what the board assumes.

What the $50,000 cap means for unit owners

When a master policy carries a per-unit deductible, Fannie now requires the individual unit owner to hold a policy (usually an HO-6) that covers that owner's share of the deductible. A $50,000 master deductible does not disappear. It lands on whichever unit's loss triggered the claim, and the HO-6 is what stands between the owner and a five-figure bill.

The mechanism most owners miss is loss assessment coverage. A standard HO-6 often includes only $2,000 of it, far short of a $50,000 deductible share, though the limit can be raised with a supplemental loss assessment endorsement. That endorsement pays only when a covered peril triggers the assessment, not for routine special assessments like a planned roof replacement. Sizing the master limits and matching the unit-owner side to them is its own exercise, which the condo master policy minimum insurance limits breakdown walks through in detail.

Fannie's 15% reserve rule takes effect in 2027

Separate from insurance, Fannie's 2026 update raises the reserve bar. For loan applications dated on or after January 4, 2027, a condo budget must fund replacement reserves at a minimum of 15% of annual assessment income, up from 10%. An association with a reserve study completed or updated in the last three years, funded at the study's highest recommended level, is exempt from the flat 15% test.

Underfunded reserves and a non-compliant insurance program fail the same review for the same reason: they make a project non-warrantable, so no unit in it qualifies for a conventional loan. A board sitting at 11% reserves has until early 2027 to raise assessments or commission a reserve study, and raising dues is rarely a quick vote. The link between reserves, insurance, and eligibility is the through-line in warrantable vs non-warrantable condo insurance.

How lenders verify condo insurance at closing

A lender confirms a project's coverage through two documents: evidence of the master policy and a completed condo project questionnaire. For the master property policy, lenders generally want an ACORD 28 (Evidence of Commercial Property Insurance), which states limits and loss-payee protections that the residential ACORD 27 leaves out. The questionnaire is where the deductible, coverage form, and reserve funding get reported.

The questionnaire is also where a project fails without anyone reading the policy, because a single wrong answer on the deductible or reserve line flags the file. The details lenders demand, and the mistakes that stall a closing, sit in the condo insurance questionnaire the lender sends. Government-backed loans run a different track: the VA condo approval and insurance requirements and FHA's condo rules do not mirror Fannie's line for line, so a project cleared for one is not automatically cleared for the others.

What boards and managers should fix before renewal

Before the next renewal, pull the master policy declarations and check four lines against Fannie's 2026 rules: the per-unit deductible, the replacement-cost basis, the coverage form endorsement, and the liability limit. Any policy still showing a percentage deductible above $50,000 needs to be re-marketed now, not discovered at a buyer's closing.

• Convert every percentage deductible to a dollar figure and compare it to the $50,000 cap.
• Confirm the master policy is written at 100% replacement cost with the Condominium Association Coverage Form endorsement.
• Check the general liability limit is at least $1 million per occurrence.
• Verify fidelity/crime coverage reaches the management company, not just the board.
• Confirm whether the master policy is all-in or bare-walls, and publish unit-owner HO-6 requirements that match.
• Map the reserve budget against the 15% threshold arriving in January 2027.

A flat-fee brokerage like Coverwatch reviews an association's condo association insurance against these Fannie sections and flags the specific line that would fail a project review, before a renewal locks in a policy that quietly makes the building unfinanceable. The cheapest time to fix a $600,000 deductible is ninety days before renewal, not the week a seller finally has a buyer under contract.
