Is Building Insurance the Same as Property Insurance?
Not quite. Building insurance covers the structure, while property insurance is a broader term that can include belongings and liability too.

Your renewal going up without a claim or a change to the house usually comes down to rebuilding costs rising faster than the price you've been paying. Insurers adjust dwelling coverage, the part that rebuilds the structure, to keep pace with material and labor costs in your area, and that figure drives most of the premium. Check your renewal notice for the new dwelling coverage amount next to last year's. If it rose, that's likely the reason. If it didn't, the increase is worth comparing against what other insurers would charge to rebuild the same house.
Same house, different number
If the dwelling coverage on your renewal barely moved but the price did, another insurer may price the same rebuilding cost lower. Worth checking before you renew.
What's the difference between dwelling coverage and property insurance anyway
Dwelling coverage is a line on your policy. It's the dollar amount your insurer agrees to pay to rebuild your house if it's destroyed, and it's usually the single biggest number on your declarations page. Property insurance is the broader category that dwelling coverage sits inside, alongside coverage for other structures on the property like a detached garage or fence, your belongings inside the house, and liability if someone gets hurt there. A homeowners policy bundles all of that into one package. Building insurance, as a term, usually just means the dwelling part.
The dwelling number is what insurers adjust most often, and it's rarely about your house specifically. It's tied to what it would cost to rebuild a structure like yours in your area right now, using current material and labor prices. Lumber, roofing, concrete, and the cost of a contractor's time all move independently of anything happening at your address. When those costs rise, insurers raise the dwelling figure to match, and the premium follows. Your house didn't change. What it would cost to rebuild it did.
Belongings coverage and liability coverage also sit under the same policy, and either can move the price without you noticing why. Belongings coverage is often set as a percentage of dwelling coverage, so when one rises, the other usually does too. Liability limits can change on renewal as well, sometimes automatically, sometimes because your insurer adjusted its own guidelines. None of that shows up as a change to your house. It shows up as a change to the numbers behind the price.
Your declarations page lists each of these separately. Dwelling, other structures, personal property, and liability each get their own line and their own dollar figure. Comparing this year's renewal to last year's line by line will usually show which number moved and by how much. That's the figure worth bringing to another insurer, since rebuilding cost for your specific house shouldn't vary much between companies, but what they charge to insure that same cost often does.
Is building insurance a separate policy I should also have
No. Building insurance isn't a second policy sitting next to your homeowners policy. It's the part of the homeowners policy that already exists, the dwelling coverage line discussed above. If someone mentions building insurance, they're talking about the same dwelling figure on your declarations page, just using a different name for it. There's nothing extra to buy and nothing missing if you've never heard the term before.
Where this gets confusing is that building insurance is sometimes sold on its own in other contexts, like a landlord insuring a rental property with no interest in covering belongings inside it, since there aren't any that belong to them. A homeowner living in the house doesn't need that kind of split. Your policy already covers the structure, your belongings, other structures on the property, and liability, all under one roof, no separate purchase required.
What's worth checking instead is whether the dwelling amount on your policy actually matches what it would cost to rebuild your house today. This is a different question from whether the term building insurance applies to you. Rebuilding cost is specific to your house. Square footage, materials, roofline, foundation type, and local labor rates all factor into it. If that number is too low, a total loss could leave you short of what you'd need to rebuild, regardless of what the policy is called or how the premium compares to last year.
Some insurers offer extended or guaranteed replacement cost as an add-on, which pays above the stated dwelling limit if rebuilding costs run higher than expected after a major loss. That's worth asking about when comparing insurers, separate from whatever is driving this year's price increase. It doesn't change what building insurance means. It changes how much cushion exists if the dwelling figure turns out to be too low when it matters most.
Before you renew
Pull last year's declarations page and this year's side by side. Compare the dwelling figure, not just the total price, then see what another insurer would charge to rebuild the same house.
