Permits & Regulations Long Beach, CA

Hello everyone,

I'm a homeowner in Long Beach, CA, and I've been exploring the idea of building an ADU in my backyard to create additional living space and potentially some rental income. My lot is about 6,000 square feet, and my budget is somewhat modest, so I'm trying to make sure I get everything right the first time to avoid costly mistakes.

I've read through the city's website and found some basic information about ADU size limits and setbacks, but I'm still a bit confused about the specific permit requirements. Can anyone clarify the exact permits I need to apply for before starting construction?

Additionally, I’m curious about the timeline for approval. How long does it typically take from application to final green light? I’d like to avoid any unexpected delays.

Another concern I have is around parking requirements. Given my budget constraints, I’m hoping to avoid adding additional parking spaces, but I’m not fully clear on Long Beach’s stance on this.

Lastly, I've heard there might be some incentives or fee waivers for building an ADU. Does anyone know if Long Beach offers anything like this to help offset the costs?

I appreciate any insights from those who've navigated this process already or from experts who are familiar with Long Beach's regulations. Thanks in advance for your help!

Hello!

It's fantastic to hear you're considering an ADU (Accessory Dwelling Unit) in Long Beach. ADUs are a great way to maximize your property's potential, generate rental income, and contribute to the housing solutions in California. Let's dive into your questions to help you navigate this process smoothly.

### Permit Requirements

In Long Beach, you'll need to secure several permits before breaking ground on your ADU:

1. **Planning Permit**: This ensures your ADU complies with local zoning laws. Long Beach's zoning laws align with California state mandates, so you can generally expect the process to be straightforward if your design adheres to standard requirements.

2. **Building Permit**: Required for any structural work, this permit ensures the construction is up to code. You'll need detailed architectural plans for submission.

3. **Utility Permits**: Depending on your ADU's design, you might need separate permits for electrical, plumbing, and mechanical work.

4. **Environmental Review**: Typically handled within the planning permit process, but if your property is in a special zone (like a coastal zone), additional review may be required.

### Timeline

The timeline for approval can vary, but here's a general breakdown:

- **Initial Application Review**: 30-60 days. Long Beach aims for efficiency, influenced by state laws like AB-68, which mandate timely processing.
- **Revisions and Resubmissions**: If changes are needed, add about 2-4 weeks.
- **Final Approval**: Once all conditions are met, another 2-4 weeks.

In total, expect around 3-6 months from initial application to final approval, assuming no major hiccups.

### Parking Requirements

Long Beach adheres to California's ADU-friendly parking regulations. Typically, new ADUs don't require additional parking if:

- Your property is within half a mile of public transit.
- The ADU is part of an existing structure.
- The area has designated street parking.

Given Long Beach's urban layout, your property may already meet one of these exemptions, saving you the cost of additional parking spaces.

### Incentives and Fee Waivers

Long Beach offers several incentives to encourage ADU construction:

- **Impact Fee Waivers**: ADUs up to 750 square feet often qualify for waived impact fees, saving you a substantial amount.
- **Permit Fee Reductions**: Some programs reduce permit fees to promote affordable housing.
- **Financing Programs**: Local credit unions and banks may offer favorable loan terms for ADU construction.

### Costs

For Long Beach, you can expect the following cost ranges:

- **Design and Permits**: $5,000 - $15,000
- **Construction Costs**: Approximately $150 - $250 per square foot, depending on finishes and complexity.
- **Total Estimated Cost**: For a 600 square foot ADU, expect around $90,000 - $150,000.

### Steps to Get Started

1. **Research and Plan**: Utilize resources like the Long Beach Development Services website for guidelines and local ADU workshops for initial insights.

2. **Hire Professionals**: Engage an architect or designer familiar with Long Beach's ADU regulations. A seasoned contractor can offer valuable input during the design phase to ensure compliance and cost-effectiveness.

3. **Prepare Your Application**: Compile all necessary documents, including site plans, floor plans, and utility plans.

4. **Submit Your Application**: File your application with the Long Beach Development Services. Keep in touch with them to track progress and respond promptly to any requests for additional information.

### Helpful Tips

- **Engage Early with Neighbors**: Open communication can mitigate potential disputes and delays.
- **Stay Updated on Local Ordinances**: Regulations can change, so keep abreast of any local adjustments to ADU policies.
- **Consider Pre-Approved Designs**: Long Beach may offer pre-approved ADU plans that can speed up the process and reduce costs.

For further assistance, consider reaching out to local ADU experts or join community forums where homeowners share their experiences. The Long Beach Development Services office is also a valuable resource for up-to-date information and guidance.

Building an ADU is a significant investment, but with careful planning and adherence to local regulations, you can create a valuable addition to your property. Best of luck with your project!
