Austin Permit Report: September 2026, Multifamily

Permit snapshot

What got permitted

Four projects carried September’s 398 multifamily homes.

The largest is 306 homes in 78702 on 5 permits. Over the last twelve months multifamily permitting is down 18% on the year before, and it is 76% of all homes permitted in Austin. The permit holder is usually the general contractor.

Pipeline

10,179 homes permitted since January 2025 haven’t been finished yet.

That’s the supply still coming: 84% of the 12,167 homes permitted in that time. 79% are in apartment buildings (5+ homes), and five ZIPs hold 47% of them, led by 78702 (1,640) and 78758 (1,427). Most permits get built: 94% of homes permitted 2016–22 were finished.

Permit issue time

A multifamily & mixed use permit takes a median 746 days to issue.

Median days from application to issue, permits issued Oct 2025 – Sep 2026. The last column removes the slowest 10% to account for stalled applications. *44% of multifamily & mixed use permits were applied for more than three years earlier, so that figure mostly reflects a backlog clearing.

Where

Every multifamily home permitted in September was in three zip codes.

Fastest riser: 78752, from 0 to 426 multifamily homes in Jul–Sep 2026 against a year earlier. Only permits inside the City of Austin full-purpose limits are counted, so ZIPs that straddle the city line show the city’s part only.

Who’s building

GS Construction Midsouth, LLC led with 426 homes in the last six months.

Multifamily homes permitted April – September 2026, out of 2,860. The permit holder is usually the general contractor rather than the developer, and one firm can appear under several names. 10 homes on 2 permits (3%) name no holder and are not ranked.
