As　regional　drought　conditions　continue　deteriorating　around　the　world,　residential　water　use　has　been　brought　into　the　built　environment　spotlight.　Nevertheless,　the　understanding　of　water　use　behavior　in　residential　buildings　is　still　limited.　This　paper　presents　data　analytics　and　results　from　monitoring　data　of　daily　water　use　(DWU)　in　50　single-family　homes　in　Texas,　USA.　The　results　show　the　typical　frequency　distribution　curve　of　the　DWU　per　household　and　indicate　personal　income,　education　level　and　energy　use　of　appliances　all　have　statistically　significant　effects　on　the　DWU　per　capita.　Analysis　of　the　water-intensive　use　demonstrates　the　residents　tend　to　use　more　water　in　post-vacation　days.　These　results　help　generate　awareness　of　water　use　behavior　in　homes.　Ultimately,　this　research　could　support　policy　makers　to　establish　a　water　use　baseline　and　inform　water　conservation　programs.
