How to handle utility connections for an ADU in Long Beach?

Construction & Building Long Beach, CA
Hi everyone,

I'm in the process of planning an ADU on my property in Long Beach and could use some guidance on handling the utility connections. I live on a 6,000 square foot lot, and my budget is pretty tight, so I want to make sure I'm making informed decisions without breaking the bank. I've read a bit about utility connections but still have some lingering questions.

Firstly, I'm wondering if I need separate utility meters for the ADU or if it can share with the main house. Would having separate meters significantly impact costs, either upfront or ongoing? I've heard mixed opinions on this.

Secondly, I'd like to know if there are specific city requirements for water, sewer, and electrical connections that might differ from state guidelines. I want to ensure I'm compliant with Long Beach regulations.

Lastly, I've come across terms like "trenching" and "easements" during my research. Could someone explain what these entail and if there are particular challenges or costs associated with them in our area?

Any advice from those who've been through this process or professionals in the field would be greatly appreciated. I want to make sure I'm not missing any crucial steps and that I'm prepared for what's involved.

Thanks in advance for your help!

Hello,

Embarking on the journey to add an Accessory Dwelling Unit (ADU) to your Long Beach property is an exciting venture, and handling utility connections wisely is crucial to staying on budget and ensuring compliance. Let’s address your questions in detail.

### Separate vs. Shared Utility Meters

**Utility Meters**: You have the option to either share the utilities between your main house and the ADU or install separate meters. While sharing is initially cheaper, separate meters can provide more accurate billing and potentially increase the ADU’s appeal for future tenants or buyers.

1. **Costs**: Installing separate meters can be costly. For instance, separate electrical meters can range from $2,000 to $5,000, while water meters might add another $2,000 to $7,000, depending on the distance from the main line and other site-specific conditions. These are rough estimates and can vary based on site conditions and the specific contractors you engage.

2. **Benefits**: Having separate meters can simplify billing if you plan to rent out the ADU, providing each unit with its own utility bills. This setup can also help avoid disputes over utility usage.

3. **Shared Utilities**: If cost-saving is a priority, sharing the existing infrastructure is feasible. However, ensure your current system can handle the additional load, particularly for electricity and plumbing. Consult with a licensed electrician and plumber to evaluate your current system’s capacity.

### Long Beach-Specific Requirements

**Water, Sewer, and Electrical Connections**: Long Beach adheres to California state regulations but also has its own local ordinances. Here’s what you need to know:

1. **Water and Sewer**: The city requires that any new construction, including ADUs, comply with existing capacity and water conservation efforts. You’ll need to work with the Long Beach Water Department to understand any specific requirements or fees. The sewer connection might involve a capacity charge, typically a few thousand dollars, based on connection size and impact assessment.

2. **Electrical**: The Long Beach Building and Safety Bureau will review your electrical plans to ensure compliance with local codes. You’ll need permits for any new electrical work, which should be factored into your timeline and budget.

3. **Permits and Inspections**: Expect to budget around $1,000 to $3,000 for various permits, depending on the complexity of your project. Timelines for approvals can range from a few weeks to a couple of months, so plan accordingly.

### Understanding Trenching and Easements

**Trenching**: This involves digging to lay down utility lines. The cost can vary significantly, often around $10 to $30 per linear foot, depending on soil conditions and depth requirements. If your lot requires extensive trenching, this can add up quickly.

**Easements**: These are rights to use a portion of the property for utilities. Ensure you have clear title and understand any existing easements on your property, as they can affect where you place utility lines. Contact the Long Beach City Clerk’s office for records and consult with a surveyor if needed.

### Tips and Warnings

- **Hiring Professionals**: Engage local professionals familiar with Long Beach regulations. This can prevent costly mistakes and streamline the permit process. Check references and previous work to ensure quality and compliance.

- **Budgeting for Contingencies**: Always budget an additional 10-15% for unexpected costs. Utility connections often reveal surprises once excavation begins.

- **Stay Informed on Legislation**: Keep abreast of California’s ADU laws like SB-9 and AB-68, which facilitate ADU construction but also come with specific requirements.

### Next Steps

1. **Consult with Local Experts**: Reach out to the Long Beach Development Services or a local ADU consultant to get a detailed analysis of your property and potential costs.

2. **Obtain Multiple Quotes**: Get multiple bids from licensed contractors for the utility work to compare costs and timelines.

3. **Plan Your Timeline**: Consider starting utility work early in the construction process, as delays here can set back your entire project.

4. **Permitting and Inspections**: Begin the permit application process early to avoid delays. Stay in touch with your assigned inspector to ensure a smooth approval process.

Embarking on your ADU project in Long Beach with these insights should help you manage utility connections effectively and maintain your budget. Good luck with your project, and feel free to reach out if you have further questions!
