Under the City of Austin HOME Initiative (Phase 1 & Phase 2), single-family lots can add detached ADUs, casitas, or duplex/three-unit infill. Austin UPC requires DFU (Drainage Fixture Unit) and WSFU load calculations to determine whether an existing 5/8″ or 3/4″ Austin Water meter can feed the ADU or requires a 1-inch tap upgrade.
