Can an ADU Share Utilities With the Main House?
When planning an ADU project, understanding how utilities connect to the main house is essential because these decisions affect costs, permits, and long-term functionality. A well-planned accessory dwelling unit considers how water, sewer, electricity, and gas will connect to the primary residence and whether the new dwelling unit will rely on existing utilities or require separate connections. Planning utility connections early helps homeowners avoid delays during the permitting process and ensures the project works efficiently for both the primary dwelling unit and the additional unit on the property.
