HO3 vs HO6 is a comparison of jobs, not qualities: the HO3 is the standard homeowners form, insuring a whole house from foundation to roof, while the HO6 is the condo unit form, insuring from the walls in because an association's master policy already carries the building. Choosing between them is automatic, your deed decides, but understanding what each covers, and how each is sized, is where owners actually go wrong.
What the HO3 carries
The HO3 bundles dwelling coverage on an open-peril basis, everything not excluded, for the structure, other structures like garages and fences, personal property on a named-peril basis, per the family the Insurance Information Institute cites, liability, medical payments and additional living expenses. Its central number is the dwelling limit, set from reconstruction cost at local prices, and its premium tracked the $1,411 US average in 2021 NAIC data reported by the III. Its structural exclusions, flood and earth movement, need separate policies, and its standard upgrades, replacement cost on contents, extended replacement cost, ordinance-or-law on older homes, complete it.
What the HO6 carries, and where the master stops
The HO6 insures unit improvements and betterments, the interior finishes on your side of the boundary the association's master deed draws, bare-walls masters leave floors, cabinets and fixtures to you, all-in masters cover original finishes, plus contents, liability, displacement and loss assessment coverage for your share of association deductibles and shortfalls. Its central numbers are two: the improvements limit at real construction prices, and the loss assessment limit sized against the master's actual deductibles, which storm-state associations pass to owners after events. The same structural exclusions apply, and the NFIP unit policy carries the flood side where water argues.
The mistakes each form invites
HO3 owners err on the dwelling limit, insuring to market price rather than rebuild cost, and on skipped endorsements, the water backup and ordinance-or-law elections whose absence surfaces at claim time. HO6 owners err on the boundary, insuring finishes the master already covers or, worse, assuming the master covers what it does not, and on loss assessment left at token defaults while their association carries a six-figure wind deductible. Both err identically on the exclusions: rising water is flood on every form, and FEMA's FloodSmart reports almost one-third of NFIP flood claims come from outside high-risk zones. The five-minute fix for both: read the declarations, and for the HO6, read the master's too.
Questions people ask about ho3 vs ho6
Which do I need, HO3 or HO6?
The deed decides: a house you own whole takes the HO3; a condo unit inside an association takes the HO6, with the master policy carrying the building.
What is the HO6's boundary?
The master deed's line: bare-walls masters leave interior finishes to your policy, all-in masters cover original finishes but not upgrades. Read it before sizing anything.
Do both forms exclude flood?
Yes, rising water is excluded from every homeowners and condo form; separate NFIP coverage carries it, and many claims arise outside mapped zones per FloodSmart.
What is loss assessment coverage?
The HO6 election paying your share when an association divides its deductible or an underinsured loss among owners. Size it against the master's real numbers.
