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

I'm a homeowner in Sacramento with a 9,000 sq ft lot, and I've been researching SB-9 to understand how it might apply to my situation. With a budget of around $200,000, I'm considering splitting my property, but I want to ensure I'm fully compliant with local regulations. From what I've gathered, SB-9 allows for lot splits and the potential for additional units, but the specifics can be quite nuanced, especially at the city level.

Here are some questions I have:

1. **Minimum Lot Size**: My current lot is 9,000 sq ft. After a potential split, what is the minimum lot size each parcel needs to be in Sacramento? I've read different requirements for various cities, and I want to ensure I'm following Sacramento's specific guidelines.

2. **Owner Occupancy Requirement**: I’ve heard that there might be an owner-occupancy requirement for one of the units post-split. Can anyone clarify how long I would need to live in one of the units in Sacramento before renting it out or selling?

3. **Permit Process and Costs**: What should I expect in terms of the permitting process and associated costs? I've accounted for construction in my budget, but I'd like a clearer picture of the potential administrative costs.

4. **Community Impact Considerations**: Are there any specific neighborhood considerations or community impact assessments that might be required here?

I really appreciate any insights or experiences you all can share, as I want to navigate this process smoothly and responsibly. Thanks in advance!

Hello there,

Navigating the nuances of SB-9, especially in Sacramento, can indeed be complex, but with the right information, you can make informed decisions about your property. Let’s dive into your questions:

### 1. Minimum Lot Size

Under SB-9, the state mandates that each parcel created through a lot split must be at least 1,200 square feet. However, local jurisdictions can impose additional rules. In Sacramento, your 9,000 sq ft lot would need to be split in a manner that neither parcel is less than 40% of the original lot size, provided each meets the 1,200 sq ft minimum. Therefore, you could split it into two parcels of 4,500 sq ft each, which aligns with both state and local requirements.

### 2. Owner Occupancy Requirement

Sacramento, like other California cities, adheres to the owner-occupancy stipulation set forth by SB-9. The law requires that one of the units on the newly split lot must be owner-occupied for at least three years from the date of the lot split approval. This is meant to ensure that homeowners remain engaged in their neighborhoods and prevent speculative sales. Be sure to document your residency to comply with this requirement.

### 3. Permit Process and Costs

The permitting process for lot splits and ADU construction in Sacramento involves several steps:

- **Pre-Application Consultation**: It's advisable to start with a consultation with Sacramento’s Planning Division. This can help clarify local zoning nuances and identify any additional requirements specific to your neighborhood.

- **Application Submission**: Complete and submit the application for a lot split. Be prepared to provide detailed site plans and project descriptions.

- **Review and Approval**: The city will review your application for compliance with zoning laws and other local ordinances. This step can take 60-90 days.

- **Permit Fees**: Sacramento's fees can vary but expect administrative costs ranging from $5,000 to $10,000, including application fees, environmental assessments, and impact fees.

- **Construction Permits**: Once your lot split is approved, you'll need separate building permits for any additional units. This could add another $3,000 to $7,000 to your costs, depending on the scope of work.

### 4. Community Impact Considerations

Sacramento places importance on community impact, particularly in established neighborhoods. You might need to conduct a neighborhood notification process or even a community meeting, depending on the scale of your project. This is to ensure that your plans align with neighborhood character and do not adversely affect the community. Engaging with local neighborhood associations early can also be beneficial.

### Additional Tips and Warnings

- **Consult a Professional**: Consider hiring a local architect or land use consultant who understands Sacramento’s specific regulations. They can provide invaluable insights and streamline your application process.

- **Budget Wisely**: While your construction budget is set at $200,000, keep a contingency reserve of around 10-15% for unforeseen expenses. Construction costs can fluctuate, and unexpected hurdles are common.

- **Stay Informed**: Regulations can change, so stay updated on local ordinances that might affect your project. Sacramento's official city website is a good resource, as is engaging with local real estate forums and community boards.

### Next Steps

1. **Schedule a Pre-Application Meeting**: Contact Sacramento’s Planning Division to discuss your project and gather more precise information tailored to your lot.

2. **Engage with Professionals**: Find a local architect and possibly a land use attorney to guide you through the process.

3. **Prepare Your Application**: Gather all necessary documents and site plans for submission. Ensure accuracy to avoid delays.

4. **Stay Connected with Your Community**: Attend local meetings and communicate with neighbors about your plans to foster support and address concerns early.

By carefully planning and leveraging professional guidance, your journey through the SB-9 process can be both rewarding and compliant. Good luck with your project, and feel free to reach out with more questions as you progress!
