Building is running ahead of the country here: 27.6 units permitted per thousand households against 11.0. Across 989,434 households that means roll-off demand from builders alongside the residential hauling.
17.4% of Austin residents moved in the last year, against 12.3% nationally. Moving is what generates junk: the garage that never got cleared, the furniture that does not fit the new place, the tenant who left half a flat behind. Across 989,434 households, that churn is the base load.
Renters occupy 41.7% of homes here, 6.9 points above the national 34.8%. With 989,434 households in the market, multifamily turnover is a standing source of scheduled work — the kind property managers call the same vendor for every month.
