Compatibility on Corridors Overview
Compatibility on Corridors Overview
The purpose of the City of Austin's compatibility standards is to ensure that there is a transition between new, potentially taller development and less tall and dense residential development. The standards include specific requirements for building height, setbacks, scale, clustering, screening, and design. These standards may be modified by the City Council to respond to changing needs and conditions within the city.
On December 1st, 2022, the City Council adopted Ordinance No. 20221201-056, which modifies compatibility and parking standards for certain corridors to increase housing capacity and support transit investments. The ordinance reduces the distance at which compatibility standards apply, and allows greater height, and thus, more housing along the corridors in exchange for affordable housing, and reduces minimum parking requirements for residential or mixed use projects on listed corridors.
More information about the amendment can be found in backup materials that were shared with the City Council here.
Frequently Asked Questions (FAQs)
The following FAQs provide more information on the existing standards, the recently adopted changes, and where they apply.
1. What are the corridors currently under consideration to be added to the Corridor Overlay?
The corridors under consideration currently are an updated E. US 290 segment to include the section between Airport Blvd and Koenig Lane as a Larger Corridor, Menchaca Rd between S. Lamar & Ben White Blvd as a Medium Corridor, Menchaca Rd between Slaughter Ln and City Limits as a Medium Corridor, and E 51st St between Manor Rd and Ed Bluestein Blvd as a Medium Corridor. Corridors were selected based on Council direction outlined in Resolution No. 20220609-066. The corridors outlined in the direction were defined as follows: Light Rail Corridors to include Project Connect Light Rail Lines and their Future Extensions, Larger Corridors to include Austin Strategic Mobility Plan Level 5 Streets and Project Connect MetroRapid Routes excluding Future Extensions, and Medium Corridors to include Imagine Austin Corridors that have been constructed but do not qualify as Light Rail or Larger Corridors and 2016 Bond Corridor Construction Program corridors that do not qualify as Light Rail or Larger Corridors. Staff used these definitions to determine properties eligible for the Corridor Overlay. Properties that are eligible for the Corridor Overlay must front face or side face one of the listed corridors.
2. What are the city-wide compatibility standards and where can I find them?
Compatibility standards can be found in Title 25, Chapter 2, Subchapter C, – Land Development, Article 10. Compatibility Standards. The City of Austin's compatibility standards generally apply to sites that are within 540 feet (or nearly two downtown blocks) of the property line of an urban family residence (SF-5) or more restrictive zoning district. Compatibility standards also apply when a site is adjacent to a lot on which a use permitted in an SF-5 or more restrictive zoning district is located.
Current compatibility standards include:
Height and Setback Limitations
Scale and Clustering Requirements
Screening Requirements
The height and setback requirements of the city-wide compatibility standards are shown in the image below. Note: Compatibility height standards are applied in addition to any restrictions that apply to a site based on its base zoning, so depending on the zoning of the site, actual allowed heights could be lower than those shown on the diagram below. For example, most commercial zoning has a 60- or 65-foot height limit.
3. What are the existing off-street parking standards and where can I find them?
The City of Austin’s existing parking requirements can be found in Title 25, Chapter 6 – Land Development, Appendix A. -Tables of Off-Street Parking and Loading 271 Requirements. For multi-family residential development, the minimum off-street parking requirements are:
- Efficiency dwelling unit: 1 space
- 1 bedroom dwelling unit: 1.5 spaces
- Dwelling unit larger than 1 bedroom: 1.5 spaces plus 0.5 space for each additional bedroom
4. What are the recently adopted changes to compatibility standards on certain corridors?
The adopted amendment generally relaxes compatibility requirements for a residential or mixed-use project on sites with frontage along a defined set of corridors: Medium, Larger, or Light Rail Corridor. For all residential or mixed-use projects on sites with frontage along a corridor:
- Compatibility restrictions will end at 200’ from a triggering property on a Larger or Light Rail Corridor
- Compatibility restrictions will end at 300’ from a triggering property on a Medium Corridor
- Compatibility restrictions will be triggered by zoning only (not by use)
- Compatibility restrictions will only apply if the triggering property is on the same side of the corridor as the site
- An additional 5’ of compatibility height will be allowed
- Projects providing affordable housing may be granted a further reduction in compatibility. For residential or mixed-use projects sites with frontage along a corridor that provides affordable housing that meets the requirements of the code:
- Compatibility restrictions will end at 100’ from a triggering property on a Light Rail Line or Large Corridor
- Compatibility restrictions will allow 65’ of height at a distance of 150’ from a triggering property and 90’ of height at 250’ from a triggering property on a Medium Corridor
- Minimum parking requirements are reduced for residential or mixed-use projects on sites with frontage along corridors:
- 25% of what would otherwise be required for a Light Rail Line or Larger Corridor
- 50% of what would otherwise be required for a Medium Corridor
The compatibility height and setback requirements that would apply to eligible projects on sites with frontage along Larger and Light Rail Line Corridors are shown in the image below compared with previous standards. Note: Compatibility height standards are applied in addition to any restrictions that apply to a site based on its base zoning, so depending on the zoning of the site, actual allowed heights could be lower than those shown on the diagram below. For example, most commercial zoning has a 60- or 65-foot height limit.
The compatibility height and setback requirements that would apply to eligible projects on sites with frontage along Medium Corridors are shown in the image below compared with previous standard. Note: Compatibility height standards are applied in addition to any restrictions that apply to a site based on its base zoning, so depending on the zoning of the site, actual allowed heights could be lower than those shown on the diagram below. For example, most commercial zoning has a 60- or 65-foot height limit.
5. Where can I see a list and a map of the specific corridors where the Corridor Overlay currently applies?

7. How do Austin’s city-wide compatibility standards compare to other cities?
Compared to similar regulations in Atlanta, Denver, and Seattle, Austin’s city-wide compatibility standards are significantly more restrictive. All three cities have regulations that require additional setbacks and height limits adjacent to low-density residential zoning districts, known as “protected districts”. In Atlanta, setbacks vary by zoning district, but under the 45-degree plane (see below) a building can reach at least 110 feet in height at 100 feet from the protected district’s property line. Seattle has the least restrictive height restrictions with buildings able to reach over 300 feet in height at 100 feet from the residential property line. In Denver, zoning districts with a height maximum of 70 feet can reach full height at 40 feet from protected district’s property line. Generally, zoning districts that allow more height are limited to 75 feet within 175 feet of the protected district; however, this height restriction does not apply to all zoning districts, building forms, and contexts.
