Home insurance in Katy, three counties and a reservoir to the east
Katy has two facts worth knowing before anything else. It sits in three counties, which quietly changes what a policy costs from one subdivision to the next. And its most expensive flooding on record happened to houses that were not in a mapped flood zone — which is the single strongest argument against reading a lender's requirements as a risk assessment.

Harris, Fort Bend and Waller
One address, three sets of answers
Katy sits outside the designated catastrophe area, so wind and hail stay inside the homeowners policy rather than moving to a separate windstorm policy.
That part is settled and it is settled the same way in all three counties — which makes Katy the mirror image of Pearland on the other side of the metro, where crossing a county line changes whether wind is a separate policy at all. Here the wind answer never moves. What moves is everything else:
- Harris County The eastern side of the area
- Valuation through HCAD, courts in Harris County. Second-tier for TWIA purposes and nowhere near the designated slice, so wind and hail stay inside the homeowners policy.
- Fort Bend County South of the interstate
- Valuation through the Fort Bend Central Appraisal District, courts in Fort Bend County. Inland, outside the designated catastrophe area entirely.
- Waller County The northwestern edge
- Valuation through the Waller County Appraisal District, courts in Waller County. A different territory again, and often a different fire protection class, which carriers rate on directly.
Two houses in the same school district can sit in different counties, and the difference shows up as a quote gap neither owner can account for. It is worth knowing which one your deed says before assuming somebody negotiated better.
Addicks and Barker
The flooding here happened outside the map
The homeowners policy excludes flood in Texas, everywhere, without exception. In Katy that exclusion is not a technicality — it is the main event.
Most Harris County flooding has historically occurred outside the mapped Special Flood Hazard Area, the 1 percent annual chance floodplain where a federally regulated lender is obliged to require flood insurance. The Addicks and Barker reservoirs sit immediately east of Katy, and the properties affected when they filled and released were substantially properties that no map had flagged and no lender had required a policy for.
The practical rule that falls out of it: a lender not requiring flood insurance is a statement about a map, not about your house. The mapped area describes where a requirement applies. It does not describe where water goes. Our flood insurance page covers how the separate policy is written, and the 30-day waiting period — which is the detail that removes the option of buying one when a forecast appears.
Inside the policy
What your wind and hail deductible is worth
Because wind and hail stay inside the homeowners policy here, so does the deductible that applies to them — and it is written as a percentage of your dwelling coverage rather than as a dollar amount. Multiply the two together and the result is usually the largest number you are carrying on the policy.
Our wind and hail deductible article works it through, including the case that surprises people most: a hail claim smaller than the deductible, which pays nothing at all. Roof age interacts with it directly, and that is covered on the roof age page.

Katy questions we get every week
Which county is Katy in?
Three. The city and the wider Katy area span Harris, Fort Bend and Waller counties. It decides your appraisal district, the territory a carrier rates you in, and which court would hear a license petition. Unlike Pearland, none of the three is a first-tier coastal county, so the wind answer is the same across all of them.
Is Katy in the TWIA area?
No. The designated catastrophe area in Harris County covers city limits east of State Highway 146 — La Porte, Morgan's Point, Pasadena, Seabrook and Shoreacres — and Katy is on the opposite side of the metro. Wind and hail are normally included in your homeowners policy, subject to a percentage deductible.
Do I need flood insurance if I am not in a flood zone?
It is worth serious thought here more than almost anywhere in the metro. Most Harris County flooding has historically happened outside the mapped Special Flood Hazard Area, and the Addicks and Barker reservoirs sit immediately east of Katy. A lender not requiring flood insurance is a statement about a map, not about your house.
Why is my quote different from a neighbour's a few streets away?
Often the county. A Katy address can be in Harris, Fort Bend or Waller, and territory rating, fire protection class and county-level loss history all move with that boundary. Roof age and the claims history attached to each individual property do the rest.
Does hail damage count against me even if I do not file?
Loss history follows the property, and a claim below your deductible pays nothing while still being capable of being recorded. That is a trade-off worth working through before filing rather than after — start by converting your percentage deductible into dollars so you know what the threshold actually is.
Do you have an office in Katy?
No — one office, at 360 FM 1959 in Houston, about forty-five miles east. Independent placement is done by phone and email, and the address is what decides the carrier. Monday to Thursday, 9:00 to 5:00; Friday, 9:00 to 4:00.
