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

Hello there,

Congratulations on embarking on your ADU project in Pomona! Navigating utility requirements can be challenging, but I'm here to provide you with comprehensive insights tailored to your situation. Let's address your queries one by one:

### 1. Is a separate utility meter mandatory for ADUs in Pomona, or can the ADU share the existing utilities with the main house?

In Pomona, as is common across California, the requirement for separate utility meters for ADUs can vary based on several factors, including the utility company policies and specific project details. Generally, California's state laws, including SB-13 and AB-68, encourage the development of ADUs by easing requirements, including utility connections.

**Pomona typically does not mandate separate utility meters for ADUs.** You can often connect the ADU to the existing utilities of the main house. This includes water, electricity, and sewer lines. However, it's crucial to check with local building officials and Southern California Edison (for electricity) to confirm the latest local practices, as utility companies might have specific requirements.

### 2. If a separate meter is required, what are the cost implications, including installation and ongoing charges?

Should you decide or need to install separate meters, here are some cost considerations:

- **Electricity:** Installing a separate electrical meter can range from $1,500 to $3,000. This includes the cost of the meter itself and the service upgrade if needed.
- **Water:** A separate water meter installation typically ranges from $1,000 to $2,500, depending on the complexity of the installation and the distance from the main water line.
- **Sewer:** You might incur additional connection fees, which can range from $500 to $1,500.

**Ongoing Charges:** Separate meters mean separate utility bills. This can be advantageous if you plan to rent out the ADU, as tenants can be billed directly for their usage.

### 3. Are there any benefits to having a separate meter even if it's not required, perhaps in terms of property value or ease of renting out the unit?

Yes, there are several benefits to installing a separate utility meter:

- **Rental Potential:** If you plan to rent out your ADU, a separate meter simplifies billing and avoids disputes over utility usage.
- **Property Value:** Homes with distinct living spaces can be more attractive to buyers, especially if separate metering is already in place.
- **Energy Management:** Separate metering allows for more accurate energy tracking and encourages conservation.

### 4. Does the need for a separate meter depend on the size or design of the ADU?

The size and design of your ADU typically do not dictate the requirement for separate meters. However, larger ADUs or those with more substantial electrical needs (e.g., all-electric units) might necessitate service upgrades that make separate metering more feasible or even necessary.

### Practical Advice and Next Steps

1. **Consult Local Authorities:** Contact Pomona's Building and Safety Division to get the most accurate and recent information regarding utility connections for ADUs. They can provide specific guidelines and any local amendments to state laws.

2. **Speak With Utility Providers:** Reach out to Southern California Edison and your water provider to understand the process and costs associated with installing separate meters. They can also advise on any rebates or programs that might offset costs.

3. **Hire Experienced Professionals:** Consider hiring an architect or contractor with specific experience in Pomona's ADU projects. They can navigate local regulations and streamline your project.

4. **Review California ADU Laws:** Familiarize yourself with SB-9 and AB-68, which provide streamlined approval processes and limit the imposition of excessive fees for ADUs.

### Common Mistakes to Avoid

- **Overlooking Local Ordinances:** Even if state laws are permissive, local ordinances can impose additional requirements. Always double-check with local authorities.
- **Ignoring Utility Capacity:** Ensure that your existing utilities can handle the additional load from an ADU, particularly if you opt to share meters. An electrician can perform a load calculation for your property.
- **Budgeting Inadequately:** Factor in all potential costs, including permit fees, connection fees, and potential landscaping or trenching work for utility lines.

### Conclusion

Your decision on whether to install separate utility meters for your ADU in Pomona should balance compliance with personal and financial considerations. While sharing existing utilities is often feasible and cost-effective, separate meters can enhance rental operations and potentially increase property appeal. I recommend starting with a conversation with local building officials and utility providers to tailor your approach to Pomona's specific landscape.

Best of luck with your project, and feel free to reach out with further questions as you proceed through the process!
