SB-9 (Lot Splits) Long Beach, CA
Hi everyone,

I’m a homeowner here in Long Beach, and I’ve been exploring the possibility of using SB-9 to split my lot. My property is around 7,500 square feet, and I’ve heard that SB-9 allows for lot splits, but I’m not entirely sure about all the requirements or implications. I’m working with a budget of about $150,000 for any additional construction or improvements needed after the split, and I want to ensure I’m making informed decisions every step of the way.

From what I’ve gathered, it seems like my lot size might meet the minimum requirements, but I’m unsure about the zoning regulations that could affect this process. Does anyone know if there are specific zoning districts in Long Beach that are more favorable for SB-9 lot splits?

Additionally, I’ve read that there are certain design and occupancy requirements post-split. Could anyone clarify what these might entail, especially in terms of owner occupancy? I’m also curious about how the split might impact property taxes or future resale value—are there any hidden costs I should be aware of?

I’d really appreciate insights from anyone who has gone through this process or has expertise in Long Beach real estate. I want to ensure I’m compliant with all the regulations and maximize the potential of my property. Thanks in advance for your help!

Hello there,

I’m glad to see your interest in utilizing Senate Bill 9 (SB-9) for a lot split in Long Beach. SB-9, which went into effect in January 2022, allows for certain single-family zoned properties to be divided into two lots and for the construction of additional housing units on them. Let’s dive into the specifics to help guide you through this process.

### Understanding the Basics of SB-9 in Long Beach

1. **Lot Size and Zoning Requirements:**
- **Minimum Lot Size:** SB-9 stipulates that the lot to be split must be at least 2,400 square feet. With your 7,500 square feet lot, you comfortably meet this requirement.
- **Zoning:** Your property must be in a single-family residential zone that permits such a split. Generally, Long Beach follows state law, but it’s crucial to verify if your specific zoning district has restrictions. Check with the Long Beach Development Services Department for any zoning overlays or specific neighborhood plans that might affect your property.

2. **Lot Split Requirements:**
- **Equal Division:** Each new parcel must be approximately the same size, with no parcel being smaller than 1,200 square feet.
- **Owner Occupancy:** You must sign an affidavit stating your intent to occupy one of the housing units as your primary residence for at least three years following the lot split. This is a critical requirement to prevent speculative developments.

3. **Design and Construction Considerations:**
- **Units Allowed:** After the split, each lot can accommodate up to two residential units, essentially allowing you to have up to four units on your original lot.
- **Design Standards:** Long Beach may have specific design standards for new constructions to maintain neighborhood character. These may include height restrictions, setbacks, and architectural styles.

### Financial Considerations

1. **Construction Costs:**
- Given your budget of $150,000, it’s important to plan carefully. Typical construction costs in Long Beach can range from $200 to $400 per square foot, depending on finishes and complexity. You might need to phase your project or seek additional financing.

2. **Property Taxes:**
- A lot split will likely reassess your property value, impacting property taxes. Consult with a local property tax advisor to understand these implications fully.

3. **Potential Resale Value:**
- The resale value may increase due to the additional units. However, ensure compliance with all regulations to avoid any devaluation due to non-compliance.

### Steps to Get Started

1. **Consult with Local Experts:**
- Hire a local real estate attorney or consultant familiar with Long Beach’s interpretation of SB-9 to guide you through legal and procedural nuances.

2. **Preliminary Planning:**
- Engage with a civil engineer or surveyor to draft a tentative map of the proposed lot split. This will be essential for your application to the city.

3. **Application and Approval:**
- Submit your lot split proposal to the Long Beach Planning Department. The city will review for compliance with SB-9 and any local ordinances. Expect this process to take several months.

4. **Environmental and Community Considerations:**
- Ensure no conflicts with environmental or wildlife protections. While SB-9 exempts certain CEQA reviews, local environmental reviews may still apply.

5. **Development and Construction:**
- Once approved, work closely with architects and builders to ensure that the new units comply with design standards and building codes.

### Tips and Warnings

- **Avoid Common Mistakes:** Ensure all affidavits and legal documents are correctly filed to prevent future legal issues.
- **Consider HOA and CC&Rs:** If your property is within a Homeowners Association, review any Covenants, Conditions, and Restrictions (CC&Rs) that might prohibit lot splits.
- **Community Engagement:** Communicate with neighbors to mitigate any opposition that could slow down the approval process.

### Next Steps

- **Research Local Contractors:** Start gathering quotes and timelines from contractors experienced with ADUs and lot splits in Long Beach.
- **Attend Workshops:** Check if Long Beach offers workshops or consultations on SB-9 and ADUs, as these can provide valuable insights and networking opportunities.

By following these guidelines and leveraging local resources, you can effectively navigate the SB-9 lot split process in Long Beach. Best of luck with your project, and feel free to reach out if you have more questions!
