It was a rainy Tuesday when my neighbor’s upstairs pipe burst and flooded three units, including mine. That’s when I realized my standard policy barely covered the walls-in. If you own a townhouse, you already know it sits somewhere between a single-family home and a condo. And that messy middle gets even messier when you start looking at insurance by state.
Let me back up. A few months ago, my family and I were thinking of moving from Texas to Colorado. I had always assumed townhouse coverage worked the same everywhere. Big mistake. In Texas, hailstorms and tornadoes are a real threat. Most carriers there want you to buy separate wind and hail endorsements, even for the exterior structure that your HOA’s master policy supposedly covers. But here’s the catch: many HOAs only insure the bare shell. Anything inside your walls—cabinets, flooring, your custom light fixtures—falls on you. That’s where an HO-6 policy comes in.
Now, when I started calling agents in different states, the numbers shocked me. A similar townhouse in Florida cost nearly triple the premium of one in Ohio. Why? Hurricane risk and litigation. In Florida, insurance companies have been pulling out or hiking rates because of roof claims and sinkhole risks. One agent in Orlando told me, “If your townhouse was built before 2010, expect to pay a lot more for roof coverage.” And many policies now have a separate hurricane deductible—often 2% to 5% of the dwelling value instead of a flat dollar amount.
But go up north to Illinois or Michigan, and the conversation shifts to frozen pipes and sewer backups. I remember talking to a claims adjuster near Chicago. He said the most common townhouse claim wasn’t fire or wind. It was water damage from an ice dam or a failed sump pump. And here’s the thing: standard policies rarely include sewer backup unless you add an endorsement. That might only cost forty or fifty bucks a year, but tons of owners skip it. Then spring thaw comes, and they’re stuck with a basement full of mud.
Out west, the game changes again. In California, you’ll find that many insurers stopped writing new townhouse policies altogether after the recent wildfire seasons. Some friends of mine in Santa Rosa had to go with the state’s FAIR Plan just to get basic fire coverage, then buy a separate difference in conditions policy for theft or water damage. It’s messy, expensive, and confusing. One thing they all emphasized: check your HOA’s master policy for something called “loss assessment coverage.” If a wildfire damages the common structure—roof, exterior walls, the shared garage—and the HOA’s insurance falls short, they can bill each owner for the gap. Loss assessment coverage helps pay your share.
What about the Northeast? In New York or New Jersey, older townhouses are common. Many were converted from row houses built a century ago. Older electrical systems and lead pipes mean higher premiums. I spoke with an owner in Queens who had to replace all knob-and-tube wiring before any carrier would offer a standard HO-6. And then there’s the issue of ordinance or law coverage. If your unit gets damaged and local building codes require upgrades during repairs—say, bringing the electrical panel up to modern code—that extra cost isn’t covered unless you specifically add that endorsement.

So how do you actually compare insurance by state without losing your mind? Start with the HOA bylaws. That document tells you exactly what the master policy covers. Some HOAs insure the roof and exterior walls; others only insure the structure as originally built. If they cover “studs out,” you need walls-in coverage. If they cover “bare walls,” you need everything including fixtures and built-ins. Then, call three local independent agents in the state you’re moving to. Don’t just use online quotes. Agents know which regional carriers are stable and which ones are non-renewing people left and right.
Another practical tip: ask about claims-free discounts and protective device credits. In Arizona, many companies cut your premium if you have a fire sprinkler system inside your townhouse. In Washington state, a monitored water leak detector can save you 10 to 15 percent. But these vary wildly by state,and sometimes by zip code. I learned that the hard way when I assumed my Texas alarm system would get me the same discount in Colorado. Nope. The Colorado agent said they only recognize central station burglar alarms, not smoke detectors.
After months of research, I ended up staying in Texas for now. But the process taught me something important. You cannot guess. A townhouse in Oklahoma faces tornadoes; a townhouse in South Carolina faces hurricane-driven floods; a townhouse in Minnesota faces roof collapse from heavy snow. Each state has its own insurance culture, its own legal environment, and its own set of weather demons. The same square footage, the same build year, the same HOA setup—the premium can swing by hundreds or even thousands of dollars just by crossing a state line.
If you’re shopping around, don’t just look at the price. Look at what’s excluded. Does the policy cover water backup? Does it offer guaranteed replacement cost or only actual cash value on your personal property? Is there a separate wind/hail deductible? And most importantly, does your HOA have adequate liability coverage? Because if someone slips on the common staircase and sues, the HOA’s policy pays first, but any excess could come back to you through a special assessment. That’s when loss assessment coverage becomes your best friend.
One last thing. Talk to your neighbors. I know it sounds old school, but the couple two doors down who’ve lived in that townhouse for fifteen years will tell you more than any website. They’ll know whether the local insurer paid claims quickly after that last hailstorm, or whether they fought every single homeowner. Insurance by state isn’t just about rates. It’s about whether the company actually shows up when your living room has two inches of water. And that, my friend, is something no algorithm can predict.
