How does an SB 2038 ETJ release work?

Senate Bill 2038, effective September 1, 2023, added Subchapters D and E to Chapter 42 of the Texas Local Government Code and created petition and election procedures for landowners to be released from a city's extraterritorial jurisdiction. After a valid petition, the municipality has 45 days to release the area or determine the petition invalid; if it does neither, the land is released by operation of law. There is no discretionary hearing in which the city weighs the merits, which is what makes the path predictable enough to underwrite.

Does leaving a city's ETJ always increase land value?

No. A release removes the city's subdivision review and its environmental and water-quality regulations, which matters most when a restrictive cover cap is the binding constraint on a cover-intensive highest and best use. It does not remove county regulations, TCEQ Edwards Aquifer rules, floodplain constraints, TxDOT access permitting or on-site wastewater limits. Senate Bill 1566 in 2025 also lets a city retain its water and sewer certificate of convenience and necessity over released land, so owners who depend on city utility service may gain little. The right question is whether release changes the number for that specific tract.

What did HB 2512 change about ETJ release eligibility?

HB 2512, effective September 1, 2025, narrowed SB 2038 by excluding areas under development agreements with municipalities over 900,000 in population, platted or unplatted lots under 12 acres unless bundled with other land, and single lots within platted subdivisions of 25 or more lots. The exclusions are not retroactive, so tracts eligible on August 31, 2025 could be ineligible days later. Several of the exclusions require reading development agreements and plat records rather than checking a map, which is why eligibility screening is the substantive work.

What happened with the 11017 Fitzhugh Road tract?

The ±55.58-acre tract at Fitzhugh Road and US 290 West sat inside Austin's ETJ and inside the Barton Springs contributing zone, carrying a 20% net-site-area impervious cover cap under the Save Our Springs ordinance despite being outside Austin's city limits. It was released from the ETJ under the SB 2038 petition path, which removed that cap and left county regulations and TCEQ Edwards Aquifer rules governing. The tract was brought to market at $15 million and closed with an institutional buyer in August 2026, with SCORE Property Group representing the sellers.

How an ETJ release changed what a ±55-acre US 290 tract was worth

Q: Can land outside Austin's city limits still be subject to Austin's impervious cover rules?

Yes. Texas Local Government Code §42.021 gives a city of 100,000 or more an extraterritorial jurisdiction reaching five miles past its limits. Inside that ETJ Austin has no zoning authority and levies no city property tax, but it does review subdivision plats and enforce its environmental and water-quality regulations. For land in the Barton Springs Zone that includes the Save Our Springs ordinance, which limits impervious cover to 15% of net site area in the recharge zone and 20% in the contributing zone — so an unzoned, untaxed tract in unincorporated Travis or Hays County can still carry Austin's tightest environmental standard.

A ±55.58-acre tract at 11017 Fitzhugh Road, where Fitzhugh meets US 290 West, sat inside the City of Austin’s extraterritorial jurisdiction and inside the Barton Springs contributing zone — which capped it at 20% impervious cover under the Save Our Springs ordinance. It was not in Austin’s city limits, paid no Austin city tax, and had no Austin zoning. It simply carried Austin’s tightest environmental standard because of a five-mile boundary line. Using the petition path created by Senate Bill 2038, the tract was released from Austin’s ETJ. Removing that cap changed what a developer could physically build on the site, and the property went to market at $15 million and closed with an institutional buyer in August 2026. Nothing about the dirt changed. The regulation that applied to it did.

The setup: an Austin address that was not in Austin

11017 Fitzhugh Road is in Travis County with an Austin 78736 mailing address, at one of the last large uninterrupted frontages where Fitzhugh Road meets US 290 West. On paper it looked like what it was — big, well-located Hill Country acreage on a corridor absorbing growth from both ends. In the underwriting it looked considerably worse, for a reason most buyers discover late.

Texas Local Government Code §42.021 gives a city of 100,000 or more an extraterritorial jurisdiction extending five miles past its limits. Austin’s reaches into Travis, Williamson, Hays and Bastrop counties. Inside that ETJ the city has no zoning authority and levies no city property tax, but it does review subdivision plats and it does enforce its environmental and water-quality regulations. For land in the Barton Springs Zone that means the Save Our Springs ordinance, adopted by citizen initiative in 1992, which limits impervious cover to 15% of net site area in the recharge zone and 20% in the contributing zone.

So the tract had the worst of both structures: none of the entitlement certainty that comes with being inside a city, and all of the constraint. Twenty percent of net site area — not gross acreage, but net of critical water quality zones — is a hard ceiling on what a builder can put down in buildings, drives, parking and detention. It is the number that decides whether a site supports a real project or one pad and a lot of open space.

What changed in 2023

Senate Bill 2038 took effect September 1, 2023 and added Subchapters D and E to Chapter 42 of the Texas Local Government Code. For the first time it gave ETJ landowners an exit: a petition procedure to be released from a city’s extraterritorial jurisdiction, modelled loosely on annexation procedure. The mechanics are deliberately unfriendly to cities. The municipality has 45 days to release the area or to determine that the petition is invalid; if it does neither, the land is released by operation of law. There is no discretionary hearing in which the city weighs the merits.

The 89th Legislature narrowed the statute through HB 2512, effective September 1, 2025, which carved out areas under development agreements with municipalities over 900,000 in population, platted or unplatted lots under 12 acres unless bundled with other land, and single lots within platted subdivisions of 25 or more lots. Those exclusions are not retroactive, and they are precisely why eligibility screening — not form-filing — is the valuable part of this work. Four of the six exclusions cannot be checked from GIS data. We wrote the mechanics up separately in how to get your land out of a city’s ETJ and the screening rules in who is eligible for ETJ release.

What the release actually did to the asset

Releasing the tract from Austin’s ETJ removed the jurisdictional hook that carried the Save Our Springs standard with it. Practically, three things changed for a buyer:

	Inside Austin’s ETJ	After release
Impervious cover standard	Save Our Springs — 20% of net site area in the contributing zone	Austin’s cap no longer applies; county regulations and TCEQ Edwards Aquifer rules govern
Subdivision review	City of Austin plat review in addition to the county	County process
Who a developer underwrites against	A city with no tax base interest in the tract and a restrictive environmental code	Hays and Travis County regulations plus TCEQ 30 TAC Chapter 213

Note what did not change. The Edwards Aquifer rules still apply — an approved contributing zone plan is still required for regulated activities disturbing five acres or more. Wastewater is still the corridor’s real density governor, because there is no centralized sewer at that location and disposal happens on site. Floodplain, access permitting through TxDOT, and utility capacity from the West Travis County Public Utility Agency were all unchanged. An ETJ release is not deregulation. It removes one specific and unusually restrictive layer, and on this tract that layer happened to be the binding constraint.

Why that translated into price

Development land trades on buildable product, not on acreage. When the cover cap doubles or disappears, the set of buyers who can make the site work expands — and the bid moves with it. That is the whole mechanism. A 20% net-site-area cap on Hill Country acreage crossed by drainage produces a buildable envelope that supports a modest commercial node. Take the cap off and the same dirt supports a program that institutional capital can size. The tract was brought to market at $15 million and closed in August 2026 with an institutional buyer, with SCORE representing the sellers.

Two honest caveats, because case studies are usually written with the caveats removed. First, the release was one of several things that made the deal — frontage on a corridor with strong traffic counts, scale that is genuinely scarce this close to Austin, and a seller willing to run a real marketing process all mattered. Second, leaving an ETJ is not automatically good. Senate Bill 1566 in 2025 lets a city retain its water and sewer certificate of convenience and necessity over released land, so an owner who depends on city utility service can find that the exit does not deliver what they expected. The right question is never “can I get out?” It is “does getting out change the number for this tract?” Sometimes it does not.

How to tell whether this applies to your land

Three screens, in order. Jurisdiction: confirm on the City of Austin Jurisdictions Web Map or with SCORE’s free Austin ETJ map checker whether the tract is in the ETJ, in limited-purpose jurisdiction, or in full-purpose city limits — only ETJ land can petition out. Eligibility: screen against the SB 2038 and HB 2512 exclusions, several of which require reading development agreements and plat records rather than a map. Consequence: determine what the city’s regulations are actually costing you. If your tract is in the contributing zone and your highest and best use is cover-intensive, the answer can be a large number. If you are in the recharge zone with a conservation buyer, or you rely on city utilities, it may be nothing at all.
