This page covers the execution layer for a burned house in Katy: whose permit, whose clerk, what the flood pool does to a rebuild, and what the lot is worth once the structure is written off. The statutory layer that applies identically in every Texas county sits on our page about Texas disclosure and insurance claim requirements.
Three Counties, One Postal Name
The City of Katy is one of the few municipalities in the state that spans three counties at once: Harris, Fort Bend and Waller. Surrounding it, the far larger area that everyone calls Katy is unincorporated territory, mostly Harris and Fort Bend, with no city government of any kind. Cinco Ranch, most of the Grand Parkway corridor subdivisions, and a great deal of the 77450 and 77494 postal geography are county, not city.
This matters immediately and concretely. A deed recorded in Fort Bend County costs $13 for the first page plus $4 for each page after. The same deed recorded in Harris County costs $25 for the first page plus $4 after. Both clerks index by grantor and grantee, and neither will accept a filing for property in the other's county. Owners with an heirship or probate problem discover this early, because the probate court that has to be opened is also the one in the county where the property sits.

The Reservoir Flood Pool Is the Fact That Moves the Number
A significant part of the Katy area sits inside the Barker Reservoir flood pool, land the Army Corps of Engineers can inundate during a controlled reservoir release. This is not a FEMA flood zone question and it is not answered by a standard flood-zone lookup. It is a separate, specifically enumerated item on the Texas seller's disclosure notice, which asks whether the property is located in a reservoir flood pool.
For a fire file the consequence is financial rather than legal. A rebuild inside the pool faces an insurability question that a rebuild half a mile east does not, and buyers who understand the area price that in. It also means that a property with fire damage and pool exposure has a much smaller retail buyer pool than the fire alone would suggest, which is why owners here frequently do better selling the lot than restoring the house and discovering the constraint at listing.
Permits: The Line Runs Through Subdivisions, Not Around Them
Inside the city limits, repair and demolition permits come from the City of Katy's building department. Outside them, an unincorporated Harris County address is permitted by the Harris County Permits Office in the Office of the County Engineer, and an unincorporated Fort Bend County address by that county's engineering department. The relevant fact for an owner is that no single map of "Katy" tells you which one applies. The city limit line runs through the area in an irregular shape, and adjacent streets can fall on opposite sides of it.
Unincorporated Harris County has a further wrinkle worth knowing: the county has required residential building permits for single-family and duplex homes only since 1 September 2009. Anything built in the county portion of Katy before that date went up without county residential plan review. That is a repair-scoping issue, not a legal one, but it means the as-built condition of an older county house is less documented than a city one, and surprises behind the drywall are more common.
We do not publish a Katy permit fee figure because the city has not confirmed one to us in writing, and a wrong number costs you real money. Call Katy City Hall for the current demolition and residential repair schedule before you budget. Ask specifically whether your address is inside the city limits, since much of what carries a Katy postal address is not.
What the Arithmetic Looks Like Here
Katy's dominant housing stock is brick-veneer slab-on-grade tract construction from roughly 1985 onward, in master-planned subdivisions with active homeowners associations. Two features of that stock drive the fire economics.
First, the houses are large. A 2,600 to 3,400 square foot rebuild at prevailing metro construction pricing is a $430,000 to $700,000 project before soft costs, and a partial fire that compromises the roof structure across a house that size very rarely repairs cheaper than it rebuilds. Second, the lots are ordinary. Unlike the inner loop, where dirt can carry most of the value, a Katy lot is worth what a builder will pay for one more finished parcel in a subdivision that already has hundreds. There is no teardown premium to fall back on.
The practical result is that Katy fire files cluster at the two ends. Contained kitchen and garage fires in a structurally sound house repair well and are worth restoring. Anything that opens the roof across multiple trusses tends to fail the arithmetic outright, because the rebuild cost lands near the finished value and the land underneath will not absorb the difference.

MUD Districts and the Closing You Did Not Expect
Nearly all of residential Katy outside the old city core is served by municipal utility districts rather than a city water department. A MUD is a separate taxing entity with its own board, its own bonds and its own rate structure, and it appears on the tax bill alongside the county and the school district. On a sale, the buyer receives a statutory MUD notice, and the title company obtains a certificate from the district confirming the account status.
For a burned property this creates a small but real friction. Water service to a destroyed structure is usually cut, but the account remains open with the district, and unpaid district assessments follow the property. Any unresolved balance surfaces on the title commitment and has to be cleared at closing. It is not a large sum. It is a delay if nobody starts on it until the week of funding.

Katy in the Wider Metro
The tri-county pattern here has a close analogue on the south side of the metro, where Missouri City sits astride the Fort Bend and Harris line for the same historical reasons, and the same recording-fee difference applies to a fire-damaged property in Missouri City. The permitting pattern, by contrast, matches the unincorporated territory north of the metro, so the county process described for selling a burned house in Cypress applies to the county portions of Katy almost exactly. And owners weighing a rebuild against the architectural review that comes with a master-planned deed restriction will find the same dynamic set out on our page about Sugar Land fire damage sale economics.
Katy Questions
Which County Is My Katy House In?
The City of Katy straddles Harris, Fort Bend and Waller counties, and the unincorporated areas marketed as Katy sit mostly in Harris and Fort Bend. The county determines which clerk records the deed and what that costs, and the two most common counties here charge materially different filing fees for the same document.
Does the Barker Reservoir Flood Pool Have to Be Disclosed?
Yes. The Texas seller's disclosure form asks specifically whether the property is located in a reservoir flood pool, alongside the floodplain and prior-flooding questions. For Katy properties inside the Barker pool this is a known, mapped condition, and it belongs on the form regardless of whether the property has ever taken water.
Do I Need a Permit to Demolish a Burned House in Katy?
Yes, but from different offices depending on the address. Inside the city limits the City of Katy building department issues it. Outside them, in unincorporated Harris or Fort Bend County, the county permits office does. Filing with the wrong one costs the time it takes to discover the error.
Will You Buy a Katy House With an Unpaid MUD Balance?
Yes. District assessments are handled at closing like any other lien against the property. Start the certificate request early, because the district issues it on its own schedule and it is a common cause of a closing slipping a week.
