ADU and Granny Flat Electrical Metering: A Guide for Signal Hill Homeowners
Signal Hill, California – with its beautiful Spanish-style homes nestled amongst the rolling hills and a famously temperate climate (even in winter!), is experiencing a surge of interest in Accessory Dwelling Units (ADUs) and granny flats. As more residents are creating separate living spaces on their properties, understanding the electrical requirements, particularly regarding metering, becomes crucial. Just Electric Services, with over 25 years of experience serving the San Gabriel Valley, including Signal Hill, is here to guide you through the process.
Understanding ADU Electrical Needs
Adding an ADU or granny flat often requires a new electrical service – that’s the connection from your main power source to the independent unit. However, simply installing a standard meter isn't always sufficient. Many homeowners are exploring sub-metering options.
- Separate Billing: Sub-metering allows you to accurately track electricity usage for the ADU separately, which can be beneficial for rental income or family living arrangements.
- Code Compliance: California’s electrical code (NEC) dictates specific requirements for ADUs, and correct metering is a key component of meeting those standards.
- Home Style Considerations: Signal Hill's historic homes often require careful consideration when adding new wiring or upgrades to accommodate an ADU - Just Electric Services specializes in working with older electrical systems safely and effectively.
Types of Metering for Your Signal Hill Project
There are several metering options available, each with its own implications:
- Separate Service: This involves running a completely new wire from the main service panel to the ADU. It's the most expensive but offers full independence.
- Sub-metering Within Existing Service: A single meter measures the total electricity usage of both your primary home and the ADU. This is simpler and cheaper but less granular in tracking individual usage.
- Bi-directional Metering (with a Split Panel): This offers the most flexibility, allowing for separate billing while still sharing some common circuits.
