Austin full-purpose vs. limited-purpose vs. ETJ: what each jurisdiction means for commercial property

The four labels, side by side

The City of Austin publishes its boundaries as a single GIS layer — “City of Austin Jurisdiction and Regulatory Boundaries,” last updated March 27, 2026 on the open data portal — with coded values FULL, LTD, 2MILE, and 5 Mile ETJ. The same layer drives the Jurisdictions Web Map that city departments use to determine everything from library-card eligibility to which development rules apply. Here is what each label changes for an owner or buyer of commercial land.

Full purpose: the city limits proper

Full-purpose annexation is what most people mean by “in the city.” Per the City of Austin Planning Department, in full-purpose areas the city provides full municipal services, assesses taxes, and enforces all city ordinances and regulations; residents vote in every city election and may run for office. The FY2026-27 budget adopted August 12, 2026 set the city rate at $0.579948 per $100 of assessed value, the maximum allowed without voter approval and up from $0.524017 the prior year. On a commercial parcel appraised at $5 million that is roughly $29,000 a year in city tax alone, before county, school, and any special district levies. In exchange you get zoning entitlements that lenders and developers can underwrite, Austin Water and Austin Energy service where the city holds the certificated area, and city fire, police, and street maintenance. Austin continues to add full-purpose territory by owner request — on May 21, 2026 Council annexed the 2,614-acre “Dog’s Head” tract in eastern Travis County at the owner’s request, and in July 2026 approved a 1.9-acre church tract near 11819 IH-35 and 37 acres of county right-of-way in East Austin. Since the 2019 changes to Texas annexation law, annexation is voluntary: landowners must consent.

Limited purpose: zoning without taxes or services

Limited-purpose annexation is the label that trips up out-of-market buyers. Under Texas Local Government Code §43.121, a home-rule city of more than 225,000 people may annex an area within its ETJ “for the limited purposes of applying its planning, zoning, health, and safety ordinances.” The city’s own description is blunt: limited-purpose annexation extends the city’s land development and environmental ordinances (and sometimes health and safety), but the city collects no taxes in limited-purpose areas and does not provide municipal services such as police protection. Statute backs that up — §43.130(c) bars the city from imposing a tax on property or residents in a limited-purpose area, though it may charge reasonable fees such as building inspection and permit fees. Voting is partial: residents may vote for council and on charter amendments, may not vote in bond elections, and are not eligible to run for city office.

Two things matter for a commercial owner in an LTD area. First, your land is zoned. Austin’s subdivision staff note that limited-purpose jurisdiction “has zoning and requires City review,” so a use change runs through the rezoning process exactly as it would inside the full-purpose limits. Second, limited-purpose status is designed to be temporary. Section 43.127 requires the city to annex the area for full purposes by the date in its regulatory plan and to take specific planning steps in each of the first three years, and §43.128 lets any affected person petition the district court to compel either full-purpose annexation or disannexation if the city misses the deadline. That obligation can be waived and the date postponed by written agreement between the city and a majority of affected landowners — and such a waiver binds all future owners. If you are buying LTD land, ask for that agreement in diligence; it tells you whether full-purpose annexation (and the city tax bill) is scheduled, deferred, or indefinitely waived.

ETJ: unzoned, untaxed, but not unregulated

Texas Local Government Code §42.021 sets the ETJ by population: one-half mile for cities under 5,000, one mile for 5,000–24,999, two miles for 25,000–49,999, three and a half miles for 50,000–99,999, and five miles for cities of 100,000 or more. Austin is in the last tier, so its ETJ is the unincorporated land within five miles of its full-purpose boundary that is not inside another city or another city’s ETJ; it currently extends into Travis, Williamson, Hays, and Bastrop counties. The city’s Planning Department states the limits of its authority there plainly: “there is no traditional zoning authority in the ETJ, and the City does not regulate land use. However, the City can enforce environmental regulations … approve subdivision plans, sign ordinances, and a few other non-zoning regulations.” No city taxes are collected; public safety, roads, and parks come from the county or special districts.

So what is the difference between 2 Mile ETJ and 5 Mile ETJ on the map? Both are ETJ in the statutory sense, and both carry the same headline consequences for a commercial tract: unzoned, no city property tax, city subdivision review, city water-quality and environmental standards (including the Save Our Springs rules in the Barton Springs Zone), and county-issued permits for septic, floodplain, and driveways. The 2-mile and 5-mile labels are the City of Austin’s own GIS classification of bands within that area — the city’s library system, for instance, treats both bands identically for residency. The practical advice is the same for either label: pull the Jurisdictions Web Map result, then confirm with the city’s Jurisdictional Matters staff and a Land Use Assistance meeting exactly which chapters of the Land Development Code will govern your tract before you price it.

Why the label moves the number

Jurisdiction shows up in a land valuation three ways. Entitlement risk: full-purpose and LTD tracts carry a zoning district a developer can underwrite or rezone; ETJ tracts have no zoning to grant and no zoning to fight, which is a feature for some uses and a financing problem for others. Carry cost: the city rate of $0.579948 per $100 applies only to full-purpose land, so an ETJ or LTD holding avoids it while you wait for the market. Utilities: the city lists extension of water and sewer infrastructure as a benefit of full-purpose annexation, but only where the tract is not inside another utility’s certificated service area — in the ETJ, a will-serve letter from whoever holds the CCN is the gating item, not the jurisdiction label. And since September 1, 2023, ETJ landowners have had an exit the other two categories do not: Senate Bill 2038 created petition and election paths to be released from a city’s ETJ, narrowed in 2025 by HB 2512. We cover the mechanics in who is eligible for ETJ release and what release costs and how long it takes.

How to check a specific parcel

Open the City of Austin Jurisdictions Web Map at maps.austintexas.gov/GIS/JurisdictionsWebMap, click “I want to…” and then “Find My Jurisdiction,” and enter the house number and street. The Address Description returns the label — Austin Full Purpose, Austin LTD, Austin 2 Mile ETJ, Austin 5 Mile ETJ, or another city’s jurisdiction — along with annexation history. For a faster read across many parcels, SCORE’s free Austin ETJ map checker runs on the same city boundary layer. Three cautions from our own diligence work: the appraisal district’s taxing-unit list is a lagging indicator, not a jurisdiction determination; a mailing address that says “Austin” means nothing; and split-jurisdiction tracts exist, in which case the city reviews any portion inside the full-purpose limits under city standards.

How SCORE helps

Steven Owen underwrites Austin land the way an engineer with an NYU Stern finance MBA reads a boundary map: jurisdiction first, because it sets the entitlement path, the tax carry, and the utility answer before a single comp is pulled. SCORE tracks jurisdiction, CCN service areas, and floodplain for every parcel in its proprietary Central Texas database, prepares SB 2038 ETJ release petitions for eligible owners, and represents sellers and buyers of development land across all four counties Austin’s ETJ touches. See development land and ETJ release.
