Is Flood Insurance Worth It for a Condo?
Often worth it. Your HO-6 excludes flood, and the HOA's master policy usually won't cover flood damage to your unit either.

Why your HO-6 won't save you here
Flood is excluded from your HO-6, and that holds even though the master policy covers the building's structure. The HOA's master policy almost never includes flood coverage either, since that's a separate policy insurers write against a specific flood zone and elevation. So if water rises from outside, a storm surge, a overflowing creek, heavy rain pooling against the foundation, neither policy responds, and the repair bill lands on you and possibly the HOA through a special assessment. Whether you need a flood policy depends on your unit's elevation and flood zone, which you can check through a flood map search by address. Ground-floor and below-grade units carry the most exposure. Upper floors still have some risk through shared systems, parking garages, or building mechanicals that flooding can knock out.
A separate flood policy on a condo often costs less than people expect, since it's rated on your unit and building type, not a whole house. Weigh that premium against a real repair bill. Flooring, drywall, cabinets, and your belongings are all excluded from your HO-6. If a special assessment follows a flood, having that coverage in place changes who absorbs the hit.
What a condo flood policy actually pays for
A flood policy for a condo splits the same way your HO-6 does. One part covers your unit's interior, the drywall, flooring, cabinets, appliances, and anything built in. Another part covers your personal belongings, up to a separate limit you choose. If you're on a ground floor or in a building with a below-grade parking garage or mechanical room, check what the HOA's policy actually carries for the building itself, because many associations do carry a separate flood policy on the shared structure even when they don't carry one on your unit. That gap, building covered, unit not, is exactly where a flood policy for your unit closes the hole.
Loss assessment coverage is the other piece worth checking. If flooding damages a shared area, a lobby, a parking level, the building's foundation, and the HOA doesn't have flood coverage on the master policy or its flood coverage falls short, the HOA can issue a special assessment to every owner to cover the shortfall. Many HO-6 policies include a loss assessment provision, but check whether it responds to flood specifically. Some policies exclude flood from loss assessment the same way they exclude it from the base coverage, which means you'd want the separate flood policy to reach that gap too, or a higher loss assessment limit written to include flood.
Cost depends mostly on your flood zone and your unit's elevation, including how high it sits relative to the building's lowest floor. A flood map search by address shows the zone, and some flood insurers also factor in the elevation certificate if the building has one on file. Ask the HOA whether an elevation certificate exists for the building. It can lower the rate meaningfully for upper-floor units in buildings built above the base flood elevation.
Timing matters more with flood insurance than with most other coverage. Most flood policies carry a waiting period before coverage takes effect, often around 30 days, so this isn't something to arrange the week a storm is forecast. If you're closing on a condo purchase in a flood zone, lenders may require proof of flood coverage before closing, which pushes the timing earlier than most buyers expect. Building the waiting period into the closing timeline avoids a gap where the unit is owned but not covered.
What happens if you skip it and a flood hits anyway
Without a flood policy, a flood claim has nowhere to go. The HO-6 excludes it, and the master policy likely excludes it too. FEMA disaster aid, when it's even available, is not insurance. It's typically a low-interest loan or a small grant, and it comes nowhere close to replacing flooring, cabinets, drywall, and belongings in a flooded unit. Owners who assume the HOA will absorb the cost are often surprised to learn the HOA has the same two options as them. Pay out of reserves, which are rarely built for this, or pass the shortfall to every unit owner through a special assessment.
A special assessment doesn't stay with the unit that flooded. It gets divided across the building, often by the same percentage each owner already pays in HOA dues. An upper-floor owner who never got water near their unit can still owe several thousand dollars because the parking garage or lobby flooded and the HOA's master policy didn't cover it. This is the scenario loss assessment coverage exists for, and it's worth reading that provision closely rather than assuming it applies to every peril.
Lenders add another layer to this. If the condo sits in a FEMA-designated high-risk flood zone, federal law requires a mortgage lender to keep flood insurance in force for as long as the loan exists, not just at closing. A lapse can trigger force-placed flood insurance, which the lender buys on the owner's behalf. It almost always costs more than a policy bought directly, and it typically covers only the lender's interest in the unit, not the owner's belongings or interior finishes.
Whether skipping flood coverage is a real option comes down to the flood zone designation and what the HOA's master policy actually carries. Both are worth confirming in writing rather than assuming. A building outside a flood zone with a master policy that includes flood coverage on common areas is a different situation than a ground-floor unit in a high-risk zone with an HOA that carries the minimum. The unit's flood zone and the HOA's insurance declarations page are the two documents that answer this, not a general sense of the building's risk.
Two documents settle this
Pull your unit's flood zone from a map search and ask the HOA for its insurance declarations page. Together they show whether you're exposed and whether the building's policy already covers the gap.
