Utility connection requirements for an ADU in Sherwood usually involve tying into existing water, sewer, and electrical services from the primary dwelling, or establishing new connections if capacity allows.

Electrical service often requires an upgrade to the main panel or a sub-panel installation to accommodate the ADU's demand. Gas lines can be extended from the main house or a new meter installed, depending on the site and existing infrastructure.
