Internet and networking for an ADU
An ADU can either share the main home's connection over a fiber or conduit link, or take its own internet service. Sharing is cheaper and simpler; a separate service and separate network is the better choice for a tenant.
Likely causes
It is a separate building
Distance and separate electrical service both point to fiber rather than copper between the main house and the unit.
Privacy matters when someone rents it
A tenant on the same flat network can see household devices. Either a separate service or a properly separated network solves it.
Your options
Shared connection, separate network
Fiber from the house, then a small switch and access point in the unit on its own isolated network.
Its own internet service
Cleanest for a rental, with its own billing and no dependence on the main house.
Wire during construction
Drops at the desk, TV and one ceiling location cost very little before drywall and are a project afterward.
From the field
Almost every ADU we wire later would have taken twenty minutes of conduit during construction. If the unit is being built now, that is the moment to sleeve a path to the main house.
