Waterfront Overlay subdistricts: setback lines and height limits for all sixteen

Last verified August 7, 2026 against the Austin Land Development Code · Kimbrough Gray · KiliGray Homes

Each Waterfront Overlay subdistrict sets its own setback lines and height limit. Most height rules read "the lower of X feet or the maximum height allowed in the base zoning district," so they only cut what base zoning allows. Not all: City Hall permits 100 feet outright, and Rainey Street allows more than 40 feet through a density bonus.

Applies to: Property in any subdistrict of the waterfront overlay (WO) combining district. Which subdistrict a site falls in determines its setback lines, its height cap and any rules specific to that area.

The overlay caps base zoning — it never grants height

Read the sixteen subdistricts together and one phrase repeats almost everywhere:

the lower of [X] feet or the maximum height allowed in the base zoning district

That construction only ever reduces. If your subdistrict allows 60 feet and your base district allows 40, you have 40. The subdistrict figure is a ceiling on top of the ceiling, not an entitlement.

It also means the overlay number alone never answers the question. You need both — the subdistrict cap and the base district limit — and the smaller wins.

Subdistrict	§	Height cap	Notes
Auditorium Shores	731	25 ft in primary setback · 60 ft in secondary	Ground-level floor area capped at 2,000 sq ft (primary) and 75,000 sq ft (secondary)
Balcones Rock Cliff	732	35 ft
Butler Shores	733	basewall 45 ft north / 35 ft south of Barton Springs Rd	Basewall height, not building height
East Riverside	734	96 ft — the highest in the overlay
Festival Beach	735	60 ft
Lamar	736	35 ft within 140 ft of the Johnson Creek centerline · 60 ft elsewhere	Distance from a creek, not from the lake
Montopolis / River Terrace	737	60 ft in the secondary setback
North Shore Central	738	70° envelope from 45 ft above the boundary nearest the water	Surface parking prohibited except buses, taxis, loading, transit, accessible and park access
Rainey Street	739	40 ft residential/mixed-use in CBD, then 8:1 with affordability	See downtown
Red Bluff	740	35 ft within the secondary setback	Setbacks run from the 450 ft and 440 ft contour lines; natural exterior materials required adjacent to Town Lake
South Lakeshore	741	60 ft
South Shore Central	742	basewall 45 ft north / 35 ft south of Riverside Dr	Basewall height, not building height
Travis Heights	743	45 ft between Lady Bird Lake and Riverside Dr · 60 ft elsewhere
University / Deep Eddy	744	60 ft
Zilker Park	745	45 ft
City Hall	746	70° envelope from 45 ft or 100 ft	Exempt from the distinctive-top and basewall standards; at- or above-grade surface parking prohibited

From §§25-2-731 to 746. Every figure marked as a height cap is "the lower of that number or the base zoning district maximum". Basewall entries govern the required basewall, not the whole structure.

Two of these are basewall heights, not building heights. Butler Shores and South Shore Central both give 45 feet north and 35 feet south of their respective roads — but that governs the required basewall, not the maximum height of the structure. Reading them as building caps would understate what may be built there.

Where the setback lines actually run

The 15 and 30 percent impervious cover limits apply to the primary and secondary setback areas — but each subdistrict draws those lines differently, and not all of them measure from the lake:

Auditorium Shores — 1,200 feet landward of the Town Lake shoreline east of the Union Pacific Railroad. West of the railroad with Riverside Drive frontage, the primary setback covers the entire property.
North Shore Central — three lines at once: 100 feet from the Town Lake shoreline, 60 feet from the Shoal Creek centerline and 50 feet from the Waller Creek centerline.
Rainey Street — 150 feet landward, plus 50 feet from the Waller Creek centerline.
South Lakeshore — 65 feet landward, plus 50 feet south of Lakeshore Boulevard.
City Hall — a single line, 100 feet landward.
Red Bluff — measured from contour lines rather than water: 40 feet from the 450-foot contour between Pleasant Valley Road and the Shady Lane extension, and 40 feet from the 440-foot contour from there to US 183. Its secondary line sits 110 feet beyond the primary.

Red Bluff is the one to watch. A setback measured from a topographic contour moves with the land, so it cannot be scaled off a plan the way a shoreline offset can.

Two subdistricts use an angled envelope instead of a flat cap

North Shore Central and City Hall replace a simple height number with a geometric envelope: a structure must fit within a 70 degree angle starting at a line 45 feet above the property boundary line nearest the water, the base of the angle being a horizontal plane running away from the water's surface.

The effect is like the residential tent in reverse orientation — height is bought with distance from the shoreline rather than from a side lot line.

City Hall states it as an alternative: fit the envelope or stay under 100 feet. That "or" is the ordinance's own word, and we reproduce it rather than resolving it — deciding which limb governs would be inventing a rule the section does not state.

This page does not map the subdistricts. These sections describe setback lines within a subdistrict; they do not draw the subdistrict boundaries. Which one your site falls in is a mapping question, and the answer comes from the city, not from the code text. Each subdistrict also carries further rules — ground-level transparency percentages, curb cut placement, materials — that are not reproduced here.

Common questions

How tall can you build in the Austin Waterfront Overlay?

It depends on the subdistrict, and the cap is always "the lower of" the subdistrict figure or the base zoning maximum. East Riverside is the most permissive at 96 feet; the Auditorium Shores primary setback is the most restrictive at 25 feet. Several subdistricts sit at 60 feet.

Does the Waterfront Overlay increase the height I can build?

No. Almost every subdistrict height rule reads "the lower of X feet or the maximum height allowed in the base zoning district", so the overlay can only reduce what base zoning permits, never add to it.

Which Waterfront Overlay subdistrict allows the most height?

East Riverside, at the lower of 96 feet or the base district maximum. City Hall permits up to 100 feet as an alternative to fitting a 70-degree envelope.

How is the Red Bluff subdistrict setback measured in Austin?

From topographic contour lines rather than from the water — 40 feet from the 450-foot contour between Pleasant Valley Road and the Shady Lane extension, and 40 feet from the 440-foot contour from there to US 183. The secondary line is 110 feet beyond the primary.

What is the 70 degree envelope in the Waterfront Overlay?

In North Shore Central and City Hall, a structure must fit within an envelope formed by a 70 degree angle starting at a line 45 feet above the property boundary nearest the water, with the base of the angle a horizontal plane running away from the water.

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.
