Austin Subchapter E: design standards driven by the road you front, not a boundary
It has no boundary — that is the whole point
Everyone who has dealt with Subchapter F expects the same question: am I inside the line? Subchapter E does not work that way. There is no line.

Six roadway types
Because applicability keys off the street, identifying your roadway type is the first step in any Subchapter E analysis:
- Core Transit Corridors — roads with, or expected to have, the density, use mix and transit to support walking and transit.
- Urban Roadways — roads inside the Urban Roadway Boundary that are not Core Transit Corridors or Highways.
- Suburban Roadways — roads outside that boundary that are not Core Transit, Hill Country or Highway.
- Highways — freeways, parkways, expressways and frontage roads in the metropolitan transportation plan.
- Hill Country Roadways — those identified in §25-2-1103, such as RM 2222 and Southwest Parkway.
- Internal Circulation Routes — public streets or private drives edged by a curb within a development.
Two adjoining sites can therefore face different requirements, because one fronts a corridor and the other an internal drive.
If you are building a house, this mostly is not your problem
Worth saying early, because readers arrive here from residential pages: single-family residential use is exempt from the Article 2 site development standards, and a large share of the Subchapter reaches non-residential zoning districts only.
Where it does bite on housing is multifamily and condominium development — the private common open space and pedestrian amenity standards reach those directly, and any site plan of two acres or more.
It also matters on the commercial corridors that run through residential neighborhoods, which is why several neighborhood plans point at Subchapter E rather than writing design rules of their own.
Full compliance, partial compliance, exemption
Three tiers, and which one you land in is mostly about how much you are demolishing.
Full compliance (1.2.2) is required for new construction on previously undeveloped land, and for new construction or site development where the Director determines that all buildings on the site have been or will be demolished. Clearing a site completely pulls the whole Subchapter in.
Partial compliance (1.2.3) covers everything else, and the Director decides which standards apply. A new building or addition must meet Article 2 unless compliance is genuinely prevented by the location of retained buildings, the size or nature of the proposed building, topography, protected trees or critical environmental features, or the position of water quality and detention facilities — and any waiver must be to the minimum extent required.
Article 1 also carries a minor modification provision, giving staff room to administer the standards without a formal variance.
What is in the five Articles
- Article 1 — General Provisions. Applicability, the compliance tiers and minor modifications. Read this one whatever your project.
- Article 2 — Site Development Standards. How buildings sit relative to the street and to each other: sidewalks and building placement by roadway type, connectivity, entryways, exterior lighting, screening of equipment and utilities, private common open space, shade and shelter.
- Article 3 — Building Design Standards. Physical appearance — glazing and façade relief, and options to improve building design for commercial uses of 10,000 sq ft or more.
- Article 4 — Mixed Use. Standards and incentives, including the vertical mixed use provisions and opting in under 4.3.5.C.3.
- Article 5 — Definitions.
A few scoping details worth knowing: exterior lighting applies on all roadway types in all zoning districts; religious assembly use is exempt from the glazing requirements; and office development is exempt from one Article 2 section.
How we approach a Subchapter E site
Establish the roadway type before anything else. It determines which sections are even in play, and getting it wrong means designing to the wrong rules — or to none.
Then work out your compliance tier honestly. Teams sometimes plan a full site clearance without registering that doing so converts a partial-compliance project into a full-compliance one. That is a real cost, and it is decided by the demolition plan rather than the building design.
And read the waiver language in 1.2.3 carefully. The grounds are specific — retained buildings, topography, protected trees, critical environmental features, water quality facilities — and relief is expressly limited to the minimum extent required. It is not a general hardship provision.
Common questions
Send us an address and we will tell you what we find
We do this research ourselves on every project we take on — zoning, floodplain, watershed, trees, whether it is a legal lot. Send us an address and we will run it and tell you what we find. It works the same whether you own a vacant lot, a house you are thinking of adding a unit to, or a house you are thinking of replacing. No charge and no strings, and if it is a bad lot we will say so.
