Multifamily utility submetering involves installing individual meters to measure water, gas, or electricity usage for each residential unit within a building. This method allows landlords to accurately allocate utility costs to tenants based on their consumption, promoting fair billing practices. Additionally, submetering encourages residents to conserve resources by providing them with a direct incentive to reduce their usage. Overall, multifamily utility submetering is a fair and efficient way to manage utility expenses in shared living spaces.
