A standard landlord policy covers more than people expect and less than they assume, and the gap between those two is where investors get hurt. The policy is built around sudden, accidental damage. What it leaves out are the predictable things: flood, earthquake, wear and tear, neglect, and coverage that can quietly fall away when a property sits empty. None of these are hidden, but nobody walks you through them at the point of sale, so they tend to surface at a claim. Knowing the exclusions is how you decide which ones to close.
The absolute exclusions: flood and earthquake
Two perils are carved out of every standard policy, no exceptions. Flood is always a separate policy, and a large share of flood losses hit property the owner considered low risk. Earthquake is likewise excluded and written separately, which matters across the West and Intermountain West. These are not gaps you patch with an endorsement on the regular policy; they are their own coverage, and on the wrong property, either one can be a total loss with nothing to respond.
The predictable exclusions: wear, tear, and neglect
Insurance covers accidents, not aging. A roof that wears out, pipes that corrode, a deck that rots: these are maintenance, and the policy will not pay to replace them. The sharper edge is that deferred maintenance can also undermine a claim that would otherwise be covered, because damage traced to a long-neglected system can be reduced or denied. This is the same logic behind why claims get denied more broadly: the policy expects the building to be kept up.
The conditional gap: vacancy
This is the exclusion that catches the most owners off guard, because the coverage exists right up until it does not. Most policies restrict or suspend coverage once a property has been vacant beyond a set period, since empty buildings carry higher risk of undetected water damage, vandalism, and loss. A rental sitting empty between tenants or during a renovation can lose protection at exactly the moment it is most exposed. A vacancy endorsement or a dedicated vacant-property policy keeps it in force through the gap.
The cost gaps: code upgrades, water backup, and the roof
Some exclusions are not about whether a loss is covered, but about how much. After a covered loss, an older building often has to be rebuilt to current code, and the extra cost of those upgrades is only covered if you carry ordinance and law coverage. Water that backs up through drains and sewers is typically excluded unless you add a water backup endorsement. And in hail country, the roof may settle at actual cash value rather than replacement cost, leaving a depreciation gap. None of these are headline exclusions, but each can be a five-figure surprise.
Close the gaps that fit your property
The goal is not to buy every endorsement; it is to match the closures to your real exposure. A coastal or low-lying property needs the flood conversation. A seismic-zone building needs the earthquake one. An older building needs ordinance and law. A property between tenants needs vacancy handled. A coverage review reads your actual policy against the property’s exposure and flags which exclusions are theoretical and which are real risks worth closing, so the gaps are a choice you made rather than a surprise you discover.
