Ask a Katy homeowner where they live and you get one word. Ask a contractor who actually works here and you get a follow-up question: which Katy? Across four adjacent ZIP codes, the median year a home was built spans twenty years. In 77450 — the side of town that includes original Cinco Ranch, which broke ground in 1991 under Newland Communities — the median home dates to 1994, with a median value of $361,400. In 77449, to the northeast, the median build year is 2004 and the median value $255,900. In 77494, where Jefferson Development Company began Firethorne in 2005, the median home was built in 2011 and is valued at $476,200. And in 77493, where Cane Island opened in spring 2015 under Rise Communities, the median build year is 2014 and the median value $358,100. Those figures come from the American Community Survey's 2024 five-year estimates, with one honest caveat: ZIP-code statistical areas do not match postal boundaries exactly, and 77449 reaches into areas many locals would call Cypress. Treat them as eras, not property lines.
Twenty years is not a rounding error. It is the difference between a kitchen that is original and overdue and a kitchen that is merely not what you would have chosen. A remodeling contractor who does not ask which Katy you live in is guessing.
A 1994 house and a 2014 house are different projects
In the older ZIPs, the work is replacement-driven. A mid-1990s kitchen has usually reached the end of its first life all at once — cabinets, counters, layout, and often the plumbing and electrical behind them — which is why kitchen remodeling in 77450 tends to mean rethinking the room, not refreshing it. The same logic holds for bathroom remodeling, where thirty-year-old tubs, tile, and valves age as a set. In 77494 and 77493, the work is discretionary and upgrade-driven: finishes, an island reconfiguration, a primary bath brought up to taste rather than up to function. Same city, entirely different scope, budget shape, and sequencing. We plan them differently because they are different.
The ground under Katy varies more than people think
Two facts about the ground here are worth knowing before structural work, and neither is cause for alarm. First, the Katy area of Fort Bend County currently has the highest measured land-subsidence rate in the greater Houston region — roughly 3 centimeters per year since 2020, averaging 2.64 centimeters per year from 2021 through 2025, with one Katy-area GPS station recording about 35 centimeters of movement between 2007 and 2025. That comes from a peer-reviewed 2025 review in Groundwater. Subsidence is slow, broad, regional movement layered on top of ordinary clay behavior; it does not mean any particular home is compromised. It does mean foundation performance in Katy is its own conversation, distinct from inner-loop Houston.
Second, the soil is not uniform. Two very different soil series occur across the area. The Lake Charles series is a true Vertisol — 45 to 60 percent clay that opens cracks one to two inches wide and a foot or more deep for 60 to 90 days in most years. The Katy series, named for this very area, is an Alfisol instead: a sandy loam surface over 25 to 30 percent clay, with a seasonal perched water table rather than dramatic shrink-swell. Which one sits under your slab varies parcel to parcel, and the professional way to find out is the USDA Web Soil Survey, which reports the dominant series and its shrink-swell rating for a specific lot. Where a project needs a structural conclusion beyond that, we hand the question to a state-licensed Texas structural engineer rather than asserting it ourselves.
Your permit depends on which side of a line you sit
Katy addresses do not all answer to the same permitting office, and the differences are practical. Inside the incorporated City of Katy, residential work is permitted under the 2021 International Residential Code, adopted by Ordinance 3116 in 2023. In unincorporated Harris County, Texas Local Government Code § 233.153 governs — with a carve-out worth knowing: where a city has adopted a building code in its extraterritorial jurisdiction, the city's code controls even outside city limits. Which rules govern your parcel is an address-level question, and confirming it is part of our first week, not a surprise in month two. On the Fort Bend County side, the county issues a Development Permit triggered by any fully enclosed structure or new concrete slab of 400 square feet or more — so a 380-square-foot slab-on-grade sunroom falls below the county trigger and a 420-square-foot version does not, a distinction worth knowing at the sketch stage. And in unincorporated Waller County, development permits have been required since 2013, with fees that double if work starts before the permit issues. Sorting this out — and sequencing HOA architectural review ahead of it — is core general contractor work, and it is where a locally grounded one earns their keep.
