Before any land clearing project in Austin, the permit question comes up. The answer isn’t simple because it depends on where your property is, how much land you’re clearing, and whether any protected trees are involved. Getting this wrong costs time and money, and starting to clear without the required permits can result in stop-work orders and mitigation requirements that are expensive to fix after the fact. This guide covers which triggers require permits in Austin and the surrounding area, so you know what to confirm before any work starts.
Ace Construction Texas handles land clearing projects across Austin and Central Texas. We work with third-party permit partners on projects requiring City of Austin review or TCEQ permits, and we confirm what’s needed before estimating every project. The permit landscape in the Austin metro varies significantly between in-city properties, unincorporated county land, and the surrounding municipalities.
The Three Main Permit Triggers for Land Clearing in Austin
| Permit Type | Trigger | Issuing Authority |
| Heritage Tree Permit | Removing a Heritage Tree in Austin city limits (protected species at size threshold) | City of Austin — Austin Urban Forestry, Development Services |
| TCEQ Construction General Permit | Any land disturbance of 1+ acres (clearing, grading, excavation) | Texas Commission on Environmental Quality (TCEQ) |
| Grading / Land Disturbance Permit | Grading that affects drainage or impervious cover within city limits | City of Austin — Development Services |
| Waterfront / Environmental Overlay | Clearing near creeks, floodplains, or in overlay zones | City of Austin — specific to overlay zone requirements |
Heritage Tree Permits in Austin
Austin’s tree protection ordinance is one of the most significant permit requirements for land clearing within the city limits. The ordinance protects trees that meet specific diameter thresholds, which vary by species. Live oaks at 19 inches in diameter or greater, measured at 4.5 feet above grade, are classified as Heritage Trees and require a permit for removal. Other protected species have their own thresholds under the ordinance.
Austin Urban Forestry, part of Austin Development Services, reviews Heritage Tree removal applications. Simple tree removal requests that meet specific waiver criteria may be processed quickly. Mature trees, trees in good condition, or trees in special zones like the Waterfront Overlay require more review and often require mitigation. Mitigation can take the form of replacing or planting trees on the property, making a payment to the city’s tree fund, or a combination of both.
Heritage Tree protection also applies to trimming. Improper trimming of a Heritage Tree can result in the same fines and remediation requirements as removal without a permit. We confirm the heritage tree status at the start of every clearing project in Austin and sequence our work around any identified permit requirements.
TCEQ Construction General Permit (CGP)
Any project in Texas that involves land disturbance of one or more acres requires a Construction General Permit from TCEQ. This permit requires the preparation and implementation of a Stormwater Pollution Prevention Plan, or SWPPP. The SWPPP documents the erosion controls that will be installed on the site to prevent sediment from leaving the property and entering stormwater systems during and after construction.
Most residential land-clearing projects involving a single standard lot are less than 1 acre and do not require a CGP. Larger residential lots, acreage properties, subdivision development, and commercial projects routinely trigger the one-acre threshold. We confirm acreage and confirm CGP applicability at the start of any project where the size is close to the threshold.
The CGP application is submitted to TCEQ online before clearing begins. We work with permit partners who are experienced with SWPPP preparation and can turn this around efficiently for projects that need it.
Clearing Near Creeks and Floodplains
Properties near Barton Creek, Onion Creek, Walnut Creek, and other Austin waterways may fall under the City of Austin’s Waterfront Overlay District or Barton Springs Zone, which imposes additional vegetation-protection requirements beyond the standard ordinance. Clearing near these corridors can require review and approval from Austin’s Watershed Protection Department in addition to standard Development Services permits.
Properties in Buda near Onion Creek and in Manor near Walnut Creek also have floodplain considerations when clearing and grading. We confirm environmental overlay and floodplain status at the start of every project near these waterways rather than discovering the requirements mid-project.
Permit Requirements Outside Austin City Limits
Properties in unincorporated Travis County outside Austin’s city limits generally have fewer tree protection requirements than in-city properties, though the TCEQ CGP still applies for projects over one acre. Properties in the Hill Country Roadway Overlay District near the Austin ETJ have additional protections.
Each surrounding municipality has its own clearing and tree ordinances. Georgetown has tree protection requirements. Round Rock and Cedar Park have their own development regulations. For projects in any municipality, we confirm which ordinances apply before starting.
Properties in Hays County and Williamson County in unincorporated areas generally have lighter clearing requirements than in Austin, but the TCEQ CGP threshold still applies. We handle permit confirmations and project coordination throughout the Central Texas metro area.
How We Handle the Permit Process
Permit requirements for land clearing in Austin are not a reason to skip the project, but they are a reason to confirm requirements before scheduling. Projects that start without required permits can face stop-work orders that halt all activity on the site until compliance is achieved. Mitigation requirements imposed after unpermitted tree removal can cost significantly more than the original permit process.
We confirm permit requirements at the estimate stage, not after the contract is signed. For projects requiring Heritage Tree review, SWPPP preparation, or grading permits, we factor the permit timeline into the project schedule and work with our permit partners to move through the process efficiently. We also work with site preparation and grading scopes that follow clearing, so we can coordinate the full sequence from permit application through site-ready condition.
To schedule a site visit and discuss permit requirements for your property, call 512-265-1198 or submit an estimate request. We’ll walk the property, identify protected trees, confirm environmental overlay status, assess acreage relative to CGP thresholds, and tell you what permits your specific project requires before any work begins.
