How to use this

Utility pages stay canonical

This cluster matters commercially because some utilities publish official tester lists, others point users to county-certified tester directories or city portals, and the device expectations differ by irrigation, fire, and service-connection context. The metro page groups those routes without pretending Southern California is one authority.

Use this metro page to compare nearby utility workflows and public provider options, then drop into the exact utility page before acting on a compliance step.
