Can I design an ADU with a patio in Long Beach?

Design & Planning Long Beach, CA
Hi everyone,

I'm a homeowner in Long Beach considering adding an ADU (Accessory Dwelling Unit) to my property. Our lot is 6,500 square feet, and we’re hoping to stay within a $150,000 budget. I’ve read through some city guidelines, and it seems feasible, but I’m still unclear about a few things, especially regarding the design and planning aspects.

Firstly, I’d love to include a small patio with the ADU to create some outdoor space for tenants or guests. Does anyone know if there are specific regulations or restrictions in Long Beach that might impact including a patio in the ADU design? I want to ensure I don't exceed any lot coverage limits or encroach on required setbacks.

Additionally, I'm curious about any design guidelines I need to follow to ensure the ADU complements the main house in terms of aesthetics. Are there particular materials or design elements that I need to consider to meet city approval?

Lastly, I’ve seen some mentions of impact fees and utility connections potentially adding significant costs. Can anyone clarify how these might affect my budget, especially when adding features like a patio?

I'd greatly appreciate any insights or experiences you could share. It's a big investment, and I want to make sure I'm covering all my bases before moving forward. Thanks in advance!

Hello,

It's great to hear that you're considering adding an ADU to your property in Long Beach! An ADU can not only increase your property's value but also provide a versatile living space. Let’s dive into your questions to ensure your project is a success.

### Including a Patio in Your ADU Design

**Regulations and Restrictions:**
1. **Lot Coverage and Setbacks:** In Long Beach, the standard lot coverage for an ADU should not exceed 50% of the existing lot space. With your 6,500 square foot lot, this means you have ample room to include a patio along with your ADU without exceeding coverage limits. However, you need to observe the required setbacks. Generally, ADUs must maintain a minimum rear and side setback of 4 feet. Ensure your patio space respects these setbacks as well.

2. **Design Guidelines:** While Long Beach doesn't have overly prescriptive design requirements, your ADU should aesthetically complement the existing structures on your property. Consider using similar materials for the façade to create a cohesive look. For example, if your main house has a Spanish tile roof or stucco siding, incorporating these elements into your ADU design will likely facilitate smoother approval from city planners.

3. **Patio Specifics:** Patios are a great addition and usually don’t have separate restrictions apart from the setbacks. However, if you plan to build an overhead structure like a pergola, you might require additional permits.

### Budgeting: Impact Fees and Utility Connections

**Impact Fees:**
- Long Beach has waived impact fees for ADUs that are 750 square feet or smaller. If your ADU exceeds this size, expect fees ranging from $2,000 to $4,000.

**Utility Connections:**
- Utility costs can vary but typically range from $5,000 to $10,000 depending on the complexity of the work required. This includes connecting water, sewer, and electricity. It’s wise to consult with a local contractor early to get a more precise estimate.

### Design and Aesthetic Considerations

1. **Materials and Elements:** Choose materials that reflect the existing architecture and neighborhood style. Common materials in Long Beach include stucco, wood siding, and tile roofs.

2. **Sustainability:** Consider sustainable options like solar panels or energy-efficient windows, which can also qualify you for incentives and rebates.

### Navigating the Approval Process

1. **Planning and Permits:** Start by consulting with the Long Beach Development Services. They can provide specific guidelines and help you understand the permitting process. Typically, obtaining permits can take 4 to 6 weeks, assuming all documentation is complete and compliant.

2. **AB-68 and SB-9:** California’s AB-68 and SB-9 laws have streamlined the approval process for ADUs, making it easier to obtain necessary permits. These laws are designed to minimize local barriers and encourage the development of ADUs by reducing restrictions on lot sizes and parking requirements.

### Practical Tips

1. **Hire Experienced Professionals:** Engage with an architect or designer who has experience with ADUs in Long Beach. They can help ensure compliance with local regulations and streamline the design and approval process.

2. **Consider Future Needs:** Think about accessibility and future-proofing your ADU. Features like a zero-step entry or wider doorways can increase the unit's appeal to a broader range of tenants.

3. **Community Resources:** Attend local workshops or consult with community groups like the Long Beach Office of Sustainability, which often provides resources and guidance on ADU projects.

### Next Steps

1. **Feasibility Study:** Conduct a feasibility study with a local architect or ADU specialist to ensure your plans align with city regulations and your budget.

2. **Consultation with Long Beach Development Services:** Schedule a pre-application meeting to clarify any uncertainties and get tailored advice for your project.

3. **Budget Review:** Revisit your budget after obtaining quotes for construction, utilities, and permits to ensure you remain within your financial limits.

By following these steps, you can create a functional and aesthetically pleasing ADU with a patio that enhances your property. Best of luck with your project, and feel free to reach out if you have more questions!
