Maybe. It is generally the landlord’s responsibility to provide and pay for water for the dwelling.
The Governor has signed into law an act authorizing water sub-metering in residential tenancies. This statute overrules an advisory ruling issued previously by the Department of Public Health. The statute amends M.G.L. c. 186 by adding a new section. While paragraph (a) sets out the definitional section, the rest of the section allows the landlord to enter into with a residential tenant a new contract whereby the landlord may charge that tenant for water usage only if the landlord installs water conservation devices for all faucets, showerheads and toilets in the unit.
