A renewal notice arrives with a materially higher number and no explanation beyond the number itself. The instinctive reading is that something you did caused it. Usually, several things you had no part in did.
Homeowners premiums are built from factors at three levels: the market, your area, and your household. Understanding which is which is what makes the conversation with your agent useful.
Market-level factors
Reinsurance costs
Insurers buy their own insurance from reinsurers, to cover the possibility of catastrophic losses. When reinsurance becomes more expensive, that cost flows into primary policies across entire regions, regardless of any individual household's record.
This is one of the largest drivers of broad, simultaneous increases, and it is completely invisible from a policyholder's perspective.
Construction costs
Your dwelling limit is meant to reflect the cost to rebuild. When materials and labour cost more, the limit needed to rebuild the same house rises — and premium follows the limit.
Many policies apply an inflation guard that raises the dwelling limit automatically each year. That is generally protective, since an under-insured dwelling is a serious problem at claim time, but it does mean your premium rises even in a year when nothing else changed.
Catastrophe experience
Large-scale weather events affect pricing across a state or region, not only the households that claimed. Insurers price forward-looking risk, so a severe season influences the following year's rates broadly.
Area-level factors
Territory rating
Insurers divide states into rating territories, and rates are filed per territory. A reassessment of wildfire exposure, flood risk, hail frequency or crime statistics can move your territory's rate with nothing changing at your address.
Fire protection classification
Properties are rated partly on distance to a fire hydrant and to a responding fire station, and on that station's classification. A station closing or a reclassification changes this. It moves rarely, but when it moves it can move noticeably.
Availability in your market
When insurers reduce writing in a state, competition falls. In several states this has pushed households toward FAIR plans, the coverage of last resort, which are typically narrower and more expensive than the standard market.
Household-level factors
Claims history
Your own claims, and in many states the claims history attached to the property from previous owners. This information sits in the CLUE report, a consumer report insurers consult when pricing.
You are entitled to your own CLUE report, and to dispute inaccurate entries, under the Fair Credit Reporting Act. Errors do occur — an inquiry recorded as a claim, or a claim attributed to the wrong address.
Credit-based insurance score
Most states permit insurers to use a credit-based insurance score in pricing. It is not the same as a lending credit score, though it draws on similar data. A handful of states restrict or prohibit its use.
Roof age and condition
One of the strongest single factors in current homeowners pricing. As a roof ages, some insurers raise the premium, some restrict settlement to actual cash value, and some decline to renew.
Changes you made
Renovations that raise rebuild cost, a pool, a trampoline, certain dog breeds, or converting part of the home to business use. Some of these you are contractually required to disclose.
Discounts that ended
Frequently overlooked. A new-home discount that ages out, a claims-free discount lost after a claim, a bundling discount that ended when the other policy moved, or an alarm monitoring contract that lapsed.
How to find out which apply to you
- Compare the two declarations pages side by side — this year's and last year's. Look for a changed dwelling limit, a changed deductible, and any discount that disappeared.
- Ask for a written explanation. Many states require insurers to explain a rate increase on request, and some require notice above a threshold.
- Request your CLUE report and check every entry against your recollection.
- Ask which discounts you now qualify for. They are not always applied automatically — a new roof, an alarm, a water shutoff device, or retirement changing your occupancy pattern.
- Check your state's rate filing records. Approved rate changes are public information in most states, and your Department of Insurance can tell you where to look.
If your dwelling limit rose automatically through an inflation guard, verify that the new figure is realistic rather than simply accepting or removing it. Both an under-insured and an over-insured dwelling limit cause problems — the first at claim time, the second on every premium.
What to do with the answer
That depends entirely on your circumstances, and we are not going to pretend otherwise. Shopping around, raising a deductible, and adding mitigation features are all things people do. Each has trade-offs, and none of them is advice from us.
What is worth saying is that a premium increase driven by reinsurance and construction costs will not be fixed by switching insurers, because it affects the whole market. An increase driven by a discount that quietly ended, or by an error on your CLUE report, might be.
What we are not saying
We are not telling you your increase is unjustified, and we are not telling you to switch. Rates are filed with and reviewed by state regulators, and an increase being unwelcome does not make it improper.
What we are saying is that the number on a renewal notice is the sum of many inputs, that most of them are not about you, and that you are entitled to ask which ones moved.
Where to verify this yourself
- Your declarations pages — this year against last year.
- LexisNexis — your CLUE report, which you are entitled to under the Fair Credit Reporting Act.
- Your state Department of Insurance — rate filings, notice requirements, and whether credit-based scores are permitted in your state.
- FTC and CFPB — your rights regarding consumer reports and how to dispute errors.
