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.
Bird Song’s burst arrives after Sweet Bark’s winter activity
Bird Song Circle contributes 43 units, with twenty in April 2026 and 22 in May; one more arrives in June. Sweet Bark Street contributes 37, concentrated in December and January, with nineteen and thirteen units respectively. The two street sequences overlap little in this review. Combining them into an annual total hides when each set of authorizations entered the record.
Ermis Farm extends the pattern into later months
Ermis Farm Road adds 25 units between April and August, including nine in June. Bird Song, Sweet Bark and Ermis Farm together contribute 105 of the ZIP’s 216 units. The other 111 units are distributed elsewhere. These three street names are therefore useful filters for understanding a large part of the total, without treating them as the entire 78745 market.
The annual increase needs a separate project-timing explanation
The prior year recorded 140 units, compared with 216 in the reviewed period. Meanwhile, newly counted site groups fall from 56 to 42. That combination is not a measured increase in units per actual development: older groups can receive later authorizations. The unit records resolve to 131 base addresses. Follow those contributing records before making a conclusion about the number or size of competing projects.
Planning context: South Austin: residential cores, transition districts and Ben White.

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.
Send us an addressWe 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.
