Apartment utilities come in many shapes and sizes, but they all serve one main purpose: to make a home more livable. In the simplest terms, utilities are services that provide energy or other necessities for the operation of a residence. Common examples include electricity, natural gas, internet and cable television service, water and waste management, telephone service, and trash removal. For larger buildings such as apartment complexes or condominiums, utilities may also include services like corporate security monitoring or garage door access control systems.
