78751 Building Permits: East 55th and Avenue D Shape a Small Sample

Last reviewed September 17, 2026 · City of Austin issued permit records · Kimbrough Gray · KiliGray Homes

Two base addresses have an outsized effect on the small 78751 sample in our September 2026 review. East 55th accumulates authorizations over three months, while an Avenue D record contributes four units in May. These examples explain why the housing-mix columns cannot substitute for reading the underlying unit records.

Applies to: Austin-issued residential records in ZIP 78751; buildings with five or more units excluded.

Local findings: September 2026 review

Reviewed 2026-09-17; records observed 2026-09-15. Period: September 2025–August 2026. Findings describe that saved window; the current comparison above can advance separately.

East 55th accumulates across three separate months

The six units associated with 605 East 55th arrive as one in March, three in May and two in July 2026. Each contributing record carries one unit and has a building-number suffix. The address is therefore counted in the unit flow in three months, even though its first appearance as a project group occurs only once. Treating every monthly contribution as a newly started development would overstate the number of distinct locations.

Avenue D is visible in Units but outside the three displayed mix sizes

A single record at 4115 Avenue D contributes four units in May. Together with East 55th’s three May units, it accounts for seven of that month’s ten units across 78751. This is a concrete example of the historical series containing records beyond the one-, two- and three-unit mix columns. The columns do not provide a full decomposition of the unit total.

The annual change is smaller than these two address contributions

The review records 39 units, versus 35 previously, spread across 24 base addresses and nineteen street labels. East 55th and Avenue D together contribute ten of the 39. This makes the actual permit files particularly valuable: a four-unit annual increase does not establish broad-based growth, and the two address groups need to be understood before choosing representative small-site comparables.

Planning context: Hyde Park: local housing, design and corridor recommendations.

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.

We are homebuilders, not the City of Austin. This page explains how we read the code in practice — it is not legal advice and it is not an official determination. Always confirm with Austin Development Services before you rely on it for a project. The authoritative text is the Austin Land Development Code; permitting questions go to Austin Development Services Department.
