Fort Bend The Mistake Everyone Makes With a City Mailing Address
It is the single most common error we run into in this county, and it isn't limited to homeowners. Out-of-town contractors get it wrong. So does most of the content written about this market. The assumption goes like this: my mail says Katy, or Richmond, or Rosenberg, so that city's building code and permit process apply to my house. In Fort Bend County, that assumption is very often false, and the Texas Supreme Court has said so directly. A Texas city cannot enforce its building codes or require building permits inside its extraterritorial jurisdiction (ETJ) — that's the holding in Town of Lakewood Village v. Bizios, 493 S.W.3d 527 (Tex. 2016), for general-law cities, extended to home-rule cities like the ones in this county by Collin County v. City of McKinney, 553 S.W.3d 79 (Tex. App.—Dallas 2018). A mailing address is assigned by the post office. Jurisdiction is a legal boundary drawn somewhere else entirely, and the two rarely line up the way people assume.
Where This Actually Plays Out in Fort Bend
This isn't a hypothetical. Cinco Ranch and Aliana sit in Houston's ETJ. Pecan Grove is split between Houston's ETJ and Richmond's, with some parcels landing in neither. Harvest Green's own MUD bond disclosure describes that same three-way split. All of these communities carry city-sounding mailing addresses. None of them are under a city electrical code, because none of them are inside city limits. What cities do retain inside their ETJ is platting authority — the power to control how land is subdivided — and that's exactly where the confusion starts. People see a city reviewing a plat and assume the same city reviews electrical work. It doesn't follow, and the case law is explicit that it doesn't.
The Map Is Not Fixed
Even a correct ETJ map has a shelf life. Since SB 2038 took effect in 2023, landowners can petition or vote their way out of an ETJ entirely, and it isn't a rare, theoretical process — more than ten thousand acres have already come out of Fulshear's ETJ alone. A map that was accurate two years ago may already be wrong. That matters here specifically because Fulshear sits at the center of the county's fastest growth, which means the ground is still shifting under whatever boundary line you last looked up.
The Practical Test
Skip the map and go to the source. Two checks settle it:
- Call the city and ask about the parcel, not the neighborhood. Give them the address or the parcel ID and ask directly: is this parcel inside your corporate limits, or in your extraterritorial jurisdiction? Neighborhood names and mailing addresses mean nothing to this question — parcel-level status is the only answer that counts.
- Pull your property tax statement and look for a city line item. If a city is taxing the parcel, the parcel is inside that city. If the only line items are the county, the school district, and a MUD, there's no city in the picture at all — which also means no city electrical code applies.
- Get it in writing before you rely on it. A verbal answer from a call center is a starting point, not a record. If a permit decision or a large project hinges on jurisdiction, ask for the determination by email.
If the parcel comes back inside city limits, the applicable National Electrical Code edition varies quite a bit by which city — Fulshear and Meadows Place are still on the 2014 NEC, Missouri City and Richmond are on the 2023 NEC, and Rosenberg's own published guidance doesn't fully agree with itself on which edition applies, so that one is worth confirming directly rather than assuming. If the parcel comes back in an ETJ or fully unincorporated, there's no city electrical permit process to navigate at all — though that doesn't mean no rules apply, just that the state license and code compliance still matter regardless of who is or isn't inspecting.
Why This Matters Before You Add a Big Load
This distinction isn't academic when you're planning real work. A panel upgrade or an EV charger installation in Cinco Ranch is a different permitting conversation than the identical project a few miles away inside Houston's or Richmond's actual limits — not because the electrical work changes, but because who reviews it, if anyone, does. Pecan Grove is its own case study in how messy this can get, straddling two cities' ETJs with parts in neither; if that's your neighborhood, it's worth reading how three sets of rules apply to houses standing side by side. Knowing your actual jurisdiction before a project starts saves a permit call that never needed to happen, or catches one that does.
The takeaway: don't trust your mailing address to tell you who governs your parcel — check with the city directly and confirm it against your tax statement before you assume any city's electrical code applies to your house.
