Waltham, Massachusetts landlords rent to a tenant base that rarely stays put: Brandeis and Bentley students, lab and biotech workers on short assignments, and families cycling through Greater Boston. Most of them live in the older multifamily lining the streets off Moody Street, buildings plumbed with a single water meter and never set up for anything else. With Massachusetts water and sewer rates among the highest in the country, that one meter is an expensive arrangement. Water submetering divides the bill by unit. True Submeter installs an individual water meter on each unit and sends every tenant an automatic monthly invoice for exactly what they used, so the cost tracks the person creating it. Usage falls once tenants can see it, shared-bill disputes end, and net operating income improves. Massachusetts has particular requirements for billing tenants for water, so confirm what applies to your property before installing anything.
