SB-9 (Lot Splits) Fremont, CA
Hello everyone,

I’m a homeowner in Fremont, California, and I’m looking into the possibility of taking advantage of SB-9 to split my property. I’ve done some initial research, but I’m hoping to get a clearer understanding of the process and timeline for getting approval from the city.

My lot is about 10,000 square feet, which I believe meets the minimum size requirement. I’m working with a budget of around $150,000 for the initial phases, including planning and splitting costs. I'd love to hear from anyone who’s gone through this in Fremont or has insights into how it works here.

Firstly, what’s the typical timeline from the application submission to approval for a lot split under SB-9 in Fremont? I’d appreciate any specific steps and approximate durations involved.

Secondly, are there common constraints or challenges specific to Fremont that could potentially delay the approval process? For instance, are there neighborhood-specific regulations I should be aware of?

Thirdly, I’ve heard that infrastructure requirements, like road access and utility connections, can complicate things. How does Fremont handle these issues, and should I expect any significant costs or hurdles?

Lastly, if anyone has experience with local architects or consultants familiar with SB-9 projects, I’d be grateful for recommendations.

Thanks in advance for your insights—it’s a bit overwhelming, and I just want to ensure I’m fully prepared before moving forward!

Hello,

It's great to see you exploring the potential of SB-9 to enhance your property in Fremont. Navigating the nuances of property splitting can indeed be overwhelming, but with the right information and planning, you can streamline the process. Let's break down your questions and provide you with a clear roadmap.

### Timeline for SB-9 Lot Split Approval in Fremont

1. **Initial Research and Preparation (1-2 months):** Before submitting your application, ensure your property complies with SB-9 requirements. With your 10,000 sq ft lot, you meet the minimum size, but you should verify any specific zoning or historical district considerations unique to your neighborhood. Fremont’s planning department can provide insights into any local constraints.

2. **Application Submission and Review (3-6 months):** Once your application is submitted, the City of Fremont has a statutory requirement to process SB-9 applications within 60 days. However, this timeline can extend if there are issues or additional documentation required. It's crucial to have all necessary documents, including surveys and environmental reports, ready to avoid delays.

3. **Approval and Conditions (1-2 months post-review):** After initial review, the city may impose conditions that need to be met before final approval. These could include infrastructure upgrades or modifications to meet local code requirements.

### Common Constraints and Challenges in Fremont

- **Zoning and Neighborhood Regulations:** Fremont, like many California cities, has unique zoning laws. While SB-9 overrides some local restrictions, it's advisable to check for any specific neighborhood regulations or Homeowners’ Association (HOA) rules that might affect your project.

- **Environmental and Historical Assessments:** Properties in historical zones or areas with potential environmental impacts (e.g., flood zones) might require additional assessments, which can extend the timeline and increase costs.

### Infrastructure Requirements

- **Road Access and Utility Connections:** Fremont requires that each lot must have adequate access to public streets and utilities. If your lot split necessitates new road access or utility hookups, you may face significant costs. Utility connection fees can range from $10,000 to $20,000 depending on the services required. Engaging with Fremont’s Public Works early in your planning will help identify these needs.

- **Utility Easements:** Ensure any new lot configurations maintain compliance with existing utility easements. This can sometimes require rerouting utilities, which can add both time and cost.

### Recommendations for Local Experts

For architects and consultants, I recommend seeking professionals with experience in SB-9 projects. Firms like Dahlin Group in Pleasanton or Studio S Squared Architecture in San Jose have a solid reputation for handling complex residential projects in the Bay Area. They can provide valuable insights specific to Fremont’s requirements.

### Practical Advice and Next Steps

1. **Engage Early with City Planners:** Schedule a pre-application meeting with Fremont’s planning department. This can help clarify specific requirements and avoid common pitfalls.

2. **Budget Wisely:** Your $150,000 budget for planning and splitting is a good start, but ensure you have contingencies for unexpected costs, particularly with infrastructure.

3. **Stay Informed on Legislation:** Keep abreast of any changes to California housing laws or local ordinances that may impact your project. SB-9 is relatively new, and interpretations can evolve.

4. **Consider Professional Project Management:** If possible, engage a project manager experienced with SB-9 projects. They can coordinate between architects, the city, and contractors, potentially saving time and money.

### Resources

- **City of Fremont Planning Department:** [Fremont Planning](https://www.fremont.gov/planning)
- **California Department of Housing and Community Development:** [HCD SB-9 Page](https://www.hcd.ca.gov/sb-9)

Taking these steps will not only help streamline your approval process but also ensure that your lot split under SB-9 aligns with both your goals and regulatory requirements. If you have any more questions or need further clarification, feel free to reach out. Best of luck with your project!
