Panel and wiring questions

How deep is the trench for a detached garage or ADU?

Typically 18 to 24 inches for conduit. We can work around your landscaper.

Can an ADU get its own meter?

Sometimes. It depends on your utility's rules, and we'll walk you through them.

Do you charge for the quote?

No. An electrician looks at the job in person and quotes it, free.
