A renewal notice shows that your home insurance premium is going up. It may not show why, or tell you which part of the policy changed. Put it beside your declarations page, often called the dec page, and your latest mortgage statement if you pay insurance through escrow. Each document answers a different question.

Start with the notice

Find the current premium, the renewal premium, the policy number and the date the new price takes effect. Check whether the notice describes a renewal or a change during the current policy period. That distinction matters when you ask the insurer what happened. A higher bill alone does not tell you whether the increase came from a coverage change, a corrected property detail or a change in pricing.

Disclosure requirements vary by state. Washington’s insurance commissioner describes a requirement for insurers to explain premium increases for home and auto policies, including condominium, manufactured home and renters policies. A further Washington requirement, scheduled for March 2027, calls for insurers to identify up to three primary reasons for an increase at renewal. Those dates and rules do not establish what an insurer must send in another state. Your state insurance department is the place to check local requirements.

If the reason is unclear, use the contact details printed on the notice or bill. A written question gives you a record of what you asked. Include your name, policy number and renewal date, then ask: What changed between the old premium and the new one? Did any coverage amount, deductible or property detail change?

Use the dec page to locate the change

The dec page is a summary, not the full policy contract. It is generally sent at renewal and shows the policy period, insured names, property address, coverage amounts and premiums. It may also identify an agent or broker and a mortgage company. The Maryland Insurance Administration’s guide to declarations pages explains what these entries mean. Read the old and new pages side by side. A different total premium is more useful when you can see whether any coverage line changed with it.

Coverage A generally refers to the dwelling. Its amount is intended to reflect an estimated cost to rebuild after a covered total loss, which can differ from the home’s sale price. Coverage B generally concerns separate structures, such as a detached garage. Coverage C concerns personal property, and Coverage D concerns loss of use, such as temporary housing after a covered loss. These labels help you find the right question to ask; the full policy wording controls the coverage terms.

Check the facts behind the price

First, confirm that the dec page covers the coming policy period. An expired page cannot verify what the new policy lists. Then check every insured name, the property address and the mortgage company. If the loan was refinanced, sold or paid off, ask the insurer to confirm that its records are current. An incorrect listing can cause trouble when a claim is filed.

Next, compare the old and new dwelling amounts. Ask what estimate supports the new amount and whether the policy uses replacement cost or actual cash value where those terms appear. They mean different things. The dec page cannot tell you by itself what it would cost to rebuild your particular home. The insurer or producer can explain the estimate it used, and local building-cost information may help you assess it.

Property facts deserve their own question. Did the listed square footage, number of stories, construction details or use of the home change? Was an addition or detached structure recorded? An insurer may use such details in pricing. A higher premium does not prove a detail is wrong, but a mismatch between the policy and the home is something you can point to precisely in a written request.

Trace the change into your mortgage payment

If your mortgage has an escrow account, your servicer may collect part of the insurance premium with each monthly payment. A premium increase can therefore appear later as a higher mortgage payment. The Consumer Financial Protection Bureau lists escrowed insurance and taxes among several reasons a mortgage payment can change. An adjustable rate, an ending temporary buydown or an ending interest-only period can also affect the amount due.

Compare the new insurance premium with the insurance charge shown in your escrow information. Then look for a separate shortage amount. For example, an annual premium increase of $240 works out to $20 a month when divided evenly, but an escrow shortage could add another amount to the payment. Do not assume the whole mortgage increase came from insurance. If the entries are hard to reconcile, ask the servicer for a written breakdown and ask the insurer to confirm the premium it billed. Federal escrow rules, including Regulation X at 12 CFR 1024.17, address how servicers handle escrow accounts and provide account information.

Know what the paperwork cannot settle

A surprise increase during the policy period calls for a different question from an increase at renewal: What policy provision and state rule permit this change now? One consumer insurance expert’s response discusses possible mid-term changes, but it is not a rule that applies to every policy. The policy wording and your state insurance department are better places to check the applicable requirements.

Keep the notice, both dec pages and any written replies together. Note which question each document answers and which remains open. If an explanation still does not account for the increase, your state insurance department can provide information about its rules and consumer resources. The goal is a clear account of the dates, policy details and amounts, not a guess based on the larger bill alone.
