Do I need a separate utility meter for my Glendale ADU?

Construction & Building Glendale, CA
Hi everyone,

I'm in the early stages of planning an ADU (Accessory Dwelling Unit) on my property in Glendale, CA, and I'm trying to wrap my head around the utility requirements. My lot is just under 7,000 square feet, and I'm working with a fairly tight budget. I've read a bit about the utility setup for ADUs and I’m particularly concerned about whether I need a separate utility meter.

From what I understand, California law has some allowances for ADUs to share utilities with the primary residence, but I've also come across info suggesting that separate meters might be necessary under certain conditions. Can anyone clarify if Glendale requires a separate utility meter for an ADU, or if I can share the existing utilities with the main house?

Additionally, I’d love to know:
1. What are the pros and cons of having a separate utility meter versus sharing one with the main house?
2. If separate meters are required, how much should I factor into my budget for installation?
3. Are there any specific Glendale regulations or rebates I should be aware of regarding utility setups for ADUs?

I’ve tried digging through the city’s building codes and some contractor sites, but I’m hoping someone with firsthand experience or expertise can provide more insight. Thanks so much for your help!

Hello there!

It's fantastic that you're embarking on the journey of adding an ADU to your property in Glendale. ADUs can not only increase your property value but also provide versatile living spaces. Let’s dive into your questions about utility meters and provide you with some detailed guidance.

### Utility Meter Requirements in Glendale

In Glendale, as in much of California, the requirement for separate utility meters for ADUs largely depends on the specifics of your project and your personal preferences. According to California state laws, notably AB-68 and SB-9, ADUs can often share utility connections, including water, sewer, and electricity, with the primary residence. Glendale adheres to these state guidelines, allowing shared utilities in many cases. However, there are scenarios where separate meters might be beneficial or even required.

#### When is a Separate Meter Required or Advisable?

1. **Zoning and Usage**: If you plan to rent out the ADU separately, having a separate meter can simplify billing and tenant management. It can also be advantageous if you're considering selling the ADU as a separate unit in the future, as allowed under SB-9.

2. **Energy Efficiency and Rebates**: Sometimes, separate meters can qualify you for specific utility rebates or energy efficiency programs. It’s worth checking with Glendale Water & Power for any current incentives.

3. **Construction Requirements**: In some cases, depending on the existing load and the size of the new unit, electrical upgrades might necessitate a new meter. Consulting with a licensed electrician early in your planning process can help determine this.

#### Pros and Cons of Separate Meters

- **Pros**:
- Simplified billing for tenants.
- Potential eligibility for energy rebates.
- Independence in utility usage.

- **Cons**:
- Initial installation costs.
- Potential increase in monthly service fees.

### Cost and Budgeting

For budgeting, consider the following typical costs in Glendale:

- **Electrical Meter Installation**: Installing a new electrical meter can range from $1,500 to $3,500, depending on your existing setup and any necessary upgrades.
- **Water and Sewer Connections**: These can vary more widely, from $2,000 to $5,000, especially if trenching is required to extend lines to the ADU.

Keep in mind these are estimates, and actual costs could vary based on site conditions and specific contractor rates.

### Timeline for Installation

Utility meter installations can take anywhere from a few weeks to a couple of months, depending on the complexity of the work and permitting process. Here’s a typical timeline:

1. **Consultation with Electrician/Plumber**: 1-2 weeks to evaluate needs and provide estimates.
2. **Permitting Process**: Typically 4-6 weeks. Glendale’s Building and Safety Division is reasonably efficient, but always plan for potential delays.
3. **Installation**: 1-2 weeks post-permit approval.

### Local Considerations and Regulations

- **Permits**: Ensure you have all necessary permits from Glendale’s Building and Safety Division. This includes electrical and plumbing permits for new meter installations.
- **Rebates and Incentives**: Check with Glendale Water & Power for any current rebates for energy-efficient upgrades. They occasionally offer incentives for solar installations which could offset utility costs.

### Practical Advice and Next Steps

1. **Start with an Assessment**: Hire a professional to assess your current utility setup and discuss your ADU plans. This will give you clarity on potential costs and requirements.

2. **Contact Glendale Water & Power**: They can offer specific guidance and inform you about any incentives or special considerations.

3. **Consider Future Needs**: Think about your long-term plans for the ADU. If it will be a rental, a separate meter might make sense despite the upfront cost.

4. **Engage a Local ADU Specialist**: Working with a consultant familiar with Glendale's specifics can streamline the process significantly.

5. **Stay Informed About Laws**: Keep an eye on evolving California and local ADU regulations, as these can impact your project.

By carefully planning and consulting with professionals, you can ensure that your ADU is both a functional and financially sound investment. Best of luck with your project, and don't hesitate to reach out to local resources or forums for ongoing support!
