If you’ve ever sat down to renew your homeowners policy and wondered whether you’re paying for too much coverage — or not nearly enough — you’re not alone. It’s one of the most common questions homeowners type into Google late at night, usually right after getting a renewal notice or hearing about a neighbor’s house fire. The honest answer is that “enough” coverage looks different for every homeowner, but there’s a clear formula you can use to figure out your number with confidence.
The biggest mistake homeowners make is assuming their home insurance should match what they paid for the house or what it would sell for on the market. That’s not how it works. To estimate the dwelling coverage portion of your home insurance, multiply the square footage of your home by the local cost per foot of residential construction while taking into account any special or custom features in your home.
This matters because your home’s market value includes the land it sits on, the neighborhood, school district, and local demand — none of which need to be “rebuilt” if your house burns down or is destroyed by a storm. Insurance only cares about the cost to rebuild the structure itself. In some markets, especially ones where land values are high relative to construction costs, this means your dwelling coverage could actually be lower than your home’s sale price. In other markets — particularly rural areas where labor and materials have to travel farther — it could be higher.
Making sure you’re properly protected on your home insurance policy involves checking the limits on five separate coverages: dwelling, other structures, personal property, liability, and loss of use. Getting the dwelling number right is the foundation, because nearly every other coverage limit on your policy is calculated as a percentage of it.
One of the most frustrating things homeowners discover after a major loss is that their dwelling limit hasn’t kept pace with construction costs. Lumber, labor, roofing materials, and skilled contractor availability all fluctuate, sometimes dramatically, especially after regional disasters when demand for contractors spikes and prices follow.
This is where many policies fall short. If your dwelling limit was accurate five years ago but your insurer never adjusted it, you could be significantly underinsured without realizing it until it’s too late — during a claim, when raising your limit no longer helps.
With extended replacement cost coverage, your insurer may pay up to 105% or 125% of your dwelling coverage amount so you have enough to rebuild. Some carriers also offer an inflation guard endorsement, which automatically adjusts your dwelling limit each year based on construction cost trends in your area, so you’re not stuck doing this math yourself every renewal period.

If you want a deeper breakdown of exactly what a standard policy covers and where the gaps tend to show up, KMO Insurance Agency has a home insurance guide that walks through coverage types in more detail.
If you have a detached garage, a shed, a fence, a gazebo, or a guest house, those structures typically aren’t automatically included under your dwelling coverage — they fall under what’s called “Other Structures” coverage, sometimes labeled Coverage B on your policy.
It’s typically set at 10% of your dwelling coverage, but you can increase that limit with an endorsement if needed. For most homeowners with a standard-sized shed or detached one-car garage, that 10% is plenty. But if you’ve converted a barn into a workshop, built a large detached studio, or have a guest house on the property, that default percentage may not come close to covering a full rebuild.
The fix is simple but often overlooked: walk your property, list every structure that isn’t physically attached to your main house, and get a rough rebuild estimate for each one. If the total exceeds 10% of your dwelling limit, ask your agent about increasing Coverage B specifically rather than just bumping up your overall dwelling number.
This is the coverage category where most people guess — and guess wrong, in both directions. Insurance companies usually set your personal property limit at a fixed percentage of your dwelling coverage limit. Often set at 50% or 70%, you can usually revise the limit up or down, depending on the value of your stuff.
For a lot of households, that default percentage works out fine. But if you’ve upgraded your electronics, furniture, or appliances recently, or if you own higher-value items like musical instruments, art, or a serious tool collection, that default percentage might leave you short after a total loss.
The only real way to know is to do a home inventory — even a simple one. The best way to estimate how much personal property coverage you need is to do a home inventory. This survey can also be useful when filing a claim. Walk through each room with your phone, take photos or a short video of your belongings (open closets and drawers too), and store that footage somewhere outside your home, like cloud storage. It takes less than an hour and can make a massive difference if you ever need to file a claim.
One more thing worth understanding here is the difference between actual cash value and replacement cost coverage on your belongings. Actual cash value pays you what your five-year-old couch is worth today — depreciated. Replacement cost pays what it costs to buy a comparable new couch right now. That difference can add up to thousands of dollars across an entire household, so it’s worth confirming which type of coverage applies to your personal property.
Liability coverage often gets the least attention, but it’s arguably one of the most important parts of your policy — because unlike dwelling or personal property coverage, liability protects your overall financial picture, not just your house.
Liability coverage starts at $100,000, but choose a limit that at least matches the total value of your assets (such as bank accounts, property, and investments). If someone is injured on your property, or you’re found responsible for damage to someone else’s property, your liability coverage is what stands between that lawsuit and your savings, retirement accounts, and future wages.
A good rule of thumb: add up your savings, your home equity, your retirement accounts, and any other significant assets. If that number is higher than your current liability limit, it’s worth talking to your agent about increasing it — or pairing your home policy with an umbrella policy for additional protection at a relatively low cost.
If a covered event — a fire, major water damage, or storm damage — makes your home temporarily unlivable, loss of use coverage (sometimes called Additional Living Expenses) helps pay for the cost of living elsewhere while repairs happen. That includes hotel stays, temporary rentals, restaurant meals beyond your normal food budget, and similar extra costs.
Additional living expense coverage is usually 20% of dwelling coverage and pays for temporary living costs after a covered disaster. For most households, that default percentage is reasonable, but if repairs in your area tend to take a long time — due to contractor shortages or hard-to-source materials — it’s worth asking whether that limit would realistically cover several months of temporary housing in your local rental market, not just a couple of weeks.
So how much home insurance do you actually need? Here’s the short version: start with an accurate dwelling coverage number based on rebuild cost, not market value. Let your other structures, personal property, and loss of use limits follow as percentages of that number, but double-check each one against your actual situation rather than assuming the default percentage fits. And make sure your liability limit reflects what you’d actually have to lose in a worst-case scenario.
An insurance agent in your community is in the best position to assist you with estimating your home’s reconstruction cost and selecting your Dwelling Coverage limit. They can factor in local construction costs, your home’s specific features, and risks unique to your area — things a generic online calculator can’t always account for. The Andover Companies
