On California’s Central Coast, where rents already run high, San Luis Obispo landlords give away something they could easily be recovering: the water their Cal Poly tenants use but never pay for directly. Water submetering closes that gap. In a market this tight, the off-campus housing around Cal Poly is prized and individually owned, mostly houses and small multifamily rented room by room to students who have zero reason to watch a meter they never see. Put an individual water meter on each unit and that changes overnight. True Submeter handles the metering and the automatic monthly billing, so every tenant pays for their own use and the full water bill returns to the owner. Consumption drops, the usual disputes over a split bill go quiet, and net operating income rises, with the typical payback landing near six months. When your rent is already premium, there is no reason to leave the water on the house.
