Austin school development standards: the Austin ISD line changes everything

Last verified August 14, 2026 against the Austin Land Development Code · Kimbrough Gray · KiliGray Homes

Section 25-2-833 applies to development of a public primary or secondary educational facility, except as provided in Section 25-2-835. Inside Austin Independent School District boundaries height may not exceed the lesser of 60 feet, 30 feet within 50 feet of single-family, or 40 feet within 100 feet. A public school is exempt from floor-to-area ratio limits.

Applies to: Development of a public primary or secondary educational facility, except as provided in Section 25-2-835 (School District Development Agreements). Section 25-2-833 divides most of its requirements according to whether the facility is within or outside the boundaries of the Austin Independent School District: Subsection (B) for setbacks, Subsection (C) for height, and Subsection (D)(2) and (D)(3) for compatibility.

The line that decides everything is not on a zoning map

Almost every rule on this hub turns on zoning. §25-2-833 turns on something else: whether the school sits inside or outside the boundaries of the Austin Independent School District.

Setbacks split on it. Height splits on it. Compatibility splits on it. And an AISD boundary is a school district boundary — it does not appear on a zoning map, and it does not follow the city limit. Austin contains several other districts, and the first question on any school project is which side of that line the site falls on.

	Inside Austin ISD	Outside Austin ISD
Setback	The setbacks the chapter would normally require	25 ft from an adjoining residential use
Height, general	60 ft	No general cap stated
Within 50 ft of single-family	30 ft	2 storeys or 30 ft, whichever is less
Within 100 ft of single-family	40 ft	3 storeys or 40 ft, whichever is less
Compatibility (Article 10)	Applies — minus opaque fencing, screening and security-light shielding	Exempt, but (D)(3)(a)–(b) apply instead
Floor-to-area ratio	Exempt	Exempt

§25-2-833(B) to (D). The FAR exemption is the only line that reads the same on both sides.

Height is a ladder that runs downward as you approach houses

Inside Austin ISD the cap is the lesser of three figures: 60 feet generally, 40 feet within 100 feet of a single-family district or use, and 30 feet within 50 feet of one.

Because it takes the lesser, the nearest condition always wins. A building 40 feet from a house is inside both the 50-foot and the 100-foot bands, and 30 feet is the answer.

Outside Austin ISD the same two bands appear, but each is expressed as storeys or feet — two storeys or 30 feet, three storeys or 40 feet — again whichever is less. A generous floor-to-floor height will hit the foot limit before the storey limit, so the storeys are a ceiling on top of a ceiling rather than an alternative to one.

Schools are exempt from floor-to-area ratio limits everywhere. §25-2-833(D)(1), and the only requirement on this page that reads identically on both sides of the district line. Whatever constrains a school building, it is not FAR — it is height, setbacks, and the proximity bands above.

Compatibility applies inside, with two things carved out

Inside Austin ISD a school is subject to Article 10 (Compatibility) — with two specific reliefs. No opaque fencing or screening is required around any building, and no shielding for security lighting.

Both carve-outs point the same way. Article 10 generally wants a development screened from its neighbours; a school wants sightlines into its grounds and lit approaches after dark. The code resolves that in the school's favour, and only on those two points.

Outside Austin ISD, two standards replace the whole article

Outside the district a school is exempt from Article 10 altogether — but §25-2-833(D)(3) substitutes two standards of its own, both aimed squarely at the neighbours:

Intensive recreational uses — a swimming pool, tennis court, ball court or playground, but not a multi-use trail — may not be built 50 feet or less from adjoining property in an SF-5 or more restrictive district, or carrying a use permitted in one.
Exterior lighting must be hooded or shielded so the light source is not directly visible from that same adjoining property.

Note what the trade actually is. Inside the district, a school keeps its unshielded security lighting. Outside it, a school loses Article 10 entirely but must shield its exterior lighting. The lighting relief and the lighting duty sit on opposite sides of the same line.

A development agreement can displace all of this. §25-2-833(A) applies the section except as provided in §25-2-835 (School District Development Agreements). That section is not carried on this hub. Where an agreement exists, read it before anything here.

Common questions

How tall can a school be in Austin?

Inside Austin ISD, the lesser of 60 feet, 40 feet within 100 feet of single-family, or 30 feet within 50 feet of single-family. Outside Austin ISD, two storeys or 30 feet within 50 feet, and three storeys or 40 feet within 100 feet — whichever is less.

What setback applies to a school in Austin?

Inside Austin ISD, the setbacks the chapter would otherwise require. Outside Austin ISD, no closer than 25 feet from an adjoining residential use.

Do compatibility standards apply to Austin schools?

Inside Austin ISD, yes — except that no opaque fencing or screening around a building and no shielding for security lighting is required. Outside Austin ISD, a school is exempt from Article 10 but must meet the recreational-use setback and lighting standards in (D)(3).

Are schools subject to FAR limits in Austin?

No. A public primary or secondary educational facility is exempt from requirements limiting floor-to-area ratio.

How close can a school playground be to houses?

Outside Austin ISD, an intensive recreational use — pool, tennis court, ball court or playground, excluding a multi-use trail — may not be built 50 feet or less from adjoining property in an SF-5 or more restrictive district or carrying a use permitted in one.

Does school lighting have to be shielded in Austin?

Outside Austin ISD, yes — hooded or shielded so the source is not directly visible from adjoining SF-5-or-more-restrictive property. Inside Austin ISD, shielding for security lighting is expressly not required.

Can a school district agreement change these rules?

Section 25-2-833 applies except as provided in §25-2-835 (School District Development Agreements), so an agreement can displace it.

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.
