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

Construction & Building Anaheim, CA
Hi everyone,

I'm a homeowner in Anaheim, California, and I'm exploring the idea of adding an ADU to my property. My lot is about 7,500 square feet, and I'm trying to keep the total project budget under $150,000. I've hit a bit of a wall while researching utility requirements, particularly regarding whether I need to install a separate utility meter for the ADU.

From what I understand, Anaheim might allow shared meters, but I'm not entirely sure. Does anyone know if a separate utility meter is mandatory for ADUs in Anaheim? If I can share the existing meter, are there specific requirements or limitations in doing so?

Additionally, I'm curious about how having a separate meter might affect utility costs. Would it likely increase the monthly expenses significantly compared to sharing the existing meter? Also, are there any incentives or rebates available if I opt for a separate meter?

I've read through some city documents, but they were a bit confusing, and I want to be sure before making any commitments. Any insights or experiences you could share would be greatly appreciated. Thanks in advance for your help!

Hello!

I'm glad you're considering adding an Accessory Dwelling Unit (ADU) to your property in Anaheim. This is a great way to increase your home's value and provide additional housing options. Let's dive into your questions about utility meters, costs, and other considerations.

### Utility Meter Options in Anaheim

In Anaheim, you are not required to install a separate utility meter for your ADU, but there are pros and cons to both shared and separate meter setups.

**Shared Meter:**
- **Pros:** Using a shared meter can save you the initial cost of installing a new one, which can range from $1,500 to $3,000 or more depending on the complexity of the installation and the need for additional infrastructure.
- **Cons:** You won't be able to separate the utility usage for billing purposes, which could be a disadvantage if you're planning to rent out the ADU and want to pass utility costs onto tenants.

**Separate Meter:**
- **Pros:** This provides a clear separation of utility usage, which is useful if the ADU is being rented out. It also allows for more accurate billing and can potentially increase the attractiveness of the rental.
- **Cons:** Besides the installation cost, separate meters can sometimes lead to slightly higher utility rates due to basic service charges on each meter.

In terms of utility costs, having a separate meter might marginally increase the monthly expenses due to these service charges, which in Anaheim could be around $10 to $30 per month per meter. However, this can often be offset by charging tenants directly for their usage.

### Regulatory Considerations

California has been actively promoting ADU construction through various state laws. For instance, **SB-9** and **AB-68** have streamlined processes and reduced barriers for ADU construction. These laws override local ordinances that conflict with state mandates, so you have more leeway in adding an ADU without some of the traditional regulatory hurdles.

Anaheim's specific regulations for ADUs comply with these state laws, allowing for reduced setback requirements (as little as 4 feet for side and rear setbacks) and eliminating minimum lot size requirements. This is advantageous for your 7,500 sq. ft. lot.

### Practical Steps and Timelines

1. **Consult with the City of Anaheim Planning Department:** Reach out to them early to understand specific zoning requirements and to verify if any local amendments affect your ADU.

2. **Hire a Professional:** Consider hiring an architect or a design-build firm experienced with ADUs in Anaheim. They can help you navigate the permitting process efficiently and ensure compliance with local codes.

3. **Permitting Process:** Typically, obtaining the necessary permits in Anaheim can take anywhere from 2 to 4 months. Be prepared for this in your project timeline.

4. **Construction:** Depending on the complexity of your ADU, expect the construction phase to take between 6 to 12 months. This includes site preparation, utility connections, and finishing touches.

### Cost Considerations

Your budget of $150,000 is reasonable for a standard ADU in Anaheim, especially if you focus on cost-effective design and construction techniques. Some cost-saving measures include:
- **Prefabricated ADUs:** These can significantly cut down on construction time and labor costs.
- **Simple Design:** Keeping the design simple and functional without extensive custom features can help stay within budget.

### Incentives and Rebates

Currently, there are no specific utility rebates for installing a separate meter for an ADU in Anaheim, but it's worth checking with Anaheim Public Utilities for any updates or energy efficiency programs that might help offset costs.

### Tips and Warnings

- **Watch for Hidden Costs:** Keep an eye on potential additional costs such as landscaping, driveway adjustments, and utility line extensions.
- **Consider Future Needs:** Even if you're not renting right away, a separate meter might add future flexibility for your property.
- **Engage Neighbors Early:** It's always a good idea to keep neighbors informed about your project, as this can help avoid conflicts during construction.

### Next Steps

1. **Research Financing Options:** Look into loans specifically for ADUs, like renovation loans or home equity lines of credit.
2. **Schedule a Consultation:** Book a consultation with a local ADU specialist who can provide tailored advice for your property.
3. **Gather Estimates:** Get quotes from multiple contractors to ensure you're getting a fair price for the work needed.

By following these steps and keeping informed about local regulations, you'll be well on your way to successfully adding an ADU to your Anaheim property. Good luck with your project, and feel free to reach out if you have more questions!
