--- title: "Before You Buy a Texas Lot: A 5 Minute Check" description: "City or ETJ, platted or not, flood map, water and sewer, deed restrictions, access. The checks that decide what a Texas lot can actually hold." last_updated: "2026-11-03" --- # Before You Buy a Texas Lot: A 5 Minute Check Scroll any page of real estate listings across Texas and you'll see the same post a dozen times a day. Half an acre. City utilities ready. Not in a flood zone. Priced to sell. Some of those lots are great. Some will cost you a year. The difference usually isn't the price. It's six things you can check before you make an offer, most of them from your laptop. ## 1. City, ETJ or county? Start here Texas has three kinds of land, and each plays by different rules. Inside city limits, the city's zoning decides what you can build. Outside the city but inside its extraterritorial jurisdiction (the ETJ), the city can't zone. It can't regulate the use of a building, its height, its size or the units per acre. But its subdivision and plat rules still apply. Out in the county, there's no zoning at all, because Texas counties don't have that power. Here's the twist. Since 2023, SB 2038 lets owners petition to leave a city's ETJ, and Fort Worth alone has received release requests covering thousands of acres. A 2025 follow-up law, HB 2512, tightened the rules for small tracts, so a single small lot often can't leave on its own anymore. If a listing says "no city rules," ask which petition, and when. ## 2. Is it platted? A plat is the recorded map that makes a lot.. a lot. In Texas, splitting a tract into two or more parts generally requires a plat, whether it's done by deed, contract for deed or a metes and bounds description. That applies in cities, ETJs and counties, with some exceptions for larger tracts. Why it matters: in cities and ETJs, utilities generally can't connect water, sewer, electricity or gas to land that hasn't met the plat rules. An unplatted lot can be cheap for a reason. Ask the seller for the recorded plat, or look it up with the county clerk. ## 3. Where does the water go? "Not in a flood zone" is a claim, not a fact, until you've seen the map. Type the address into FEMA's Map Service Center. Zones starting with A or V are high risk. X is moderate to low. In the Houston area, Harris County's MAAPnext shows draft flood risk that may be ahead of the official maps. Don't count on the seller to tell you. Texas's flood disclosure form applies to residential property with a single dwelling, so a vacant lot typically won't come with one. Look at the ground too: low spots, drainage ditches and the creek two streets over. ## 4. Water, sewer and the MUD line on your tax bill "Utilities ready" can mean a tap at the property line or a main a mile away. Find out who holds the water and sewer rights for the area. The Public Utility Commission's CCN viewer shows which utility has the exclusive right to serve it. No sewer? Then you're on septic, and the state sets minimums. For newer single-family lots on their own septic system, TCEQ rules call for at least half an acre with public water, or a full acre with a private well. Older lots may be grandfathered. And check for a MUD, a Municipal Utility District. MUDs pay for water, sewer and drainage with bonds, and owners repay them through an extra property tax. The seller has to give you a MUD notice before you sign, so read it and find the current rate on the district's website. ## 5. Read the deed restrictions before you read the listing Deed restrictions are private rules recorded against the land, and they can say no where the city says yes. Single-family only. Minimum home size. No manufactured homes. They live with the county clerk, not the city. Search by subdivision, lot and block, and check Schedule B of your title commitment, where restrictions and easements are listed. If you don't object in writing, you've accepted them. ## 6. Can you get in, and what's underneath? Make sure the lot touches a public road or has a recorded easement. On a state highway, a new driveway needs a TxDOT permit from the local district office. Then look down. In Texas, the mineral estate is often sold separately, and it's the dominant estate. The Railroad Commission's GIS viewer maps wells and pipelines near the site. Finally, if the land has an agricultural valuation, changing its use triggers rollback taxes for the previous three years. Ask who pays. ## Put it together None of this needs a lawyer to start. It needs an address and a couple minutes of focus. If a lot passes all six, you've found something worth a survey and a title search. If it fails one, you've saved yourself the closing costs. Check the ground before you buy it! ## Sources 1.
