SB-9 (Lot Splits) Anaheim, CA

Hello everyone,

I'm a homeowner in Anaheim, and I've been exploring the possibility of doing a lot split under SB-9. My property is a corner lot, roughly 8,500 square feet, and I'm considering this option to create an additional dwelling space for my aging parents. I've read through some of the basics of SB-9, but I'm still unsure about a few things and would appreciate some expert guidance.

Firstly, are there specific zoning restrictions in Anaheim that might affect my ability to do a lot split under SB-9? From what I understand, SB-9 allows up to two units on each lot, but I'm not clear on how local regulations might impact this.

Secondly, I’ve heard that SB-9 requires the property owner to live on-site for a certain period. Can anyone confirm the details of this requirement? If I proceed with a lot split, can I live in one of the new units while renting out the other?

Additionally, I’m on a budget—around $100,000 for this project. Does anyone have experience with the cost of splitting a lot and constructing a new unit in Anaheim? Are there hidden costs I should anticipate?

Lastly, are there any community or environmental reviews I should be aware of before starting this process?

Thanks in advance for any advice or experiences you can share. I'm hoping to make the best decision for my family, so your insights would be invaluable!

Hello and thank you for reaching out with your questions on navigating the SB-9 lot split process in Anaheim. It's great that you're looking into this to create a living space for your parents. Let's dive into your queries step-by-step, ensuring you have a clear understanding of what's involved.

### Zoning Restrictions in Anaheim

As of the latest information, SB-9 allows homeowners to split a single-family lot into two separate lots and build up to two residential units on each lot. However, local jurisdictions, like Anaheim, can impose additional regulations. Anaheim’s zoning regulations can potentially impact your plans, especially regarding setbacks, minimum lot sizes, and parking requirements.

1. **Minimum Lot Size:** SB-9 requires each lot to be at least 1,200 square feet. Since your lot is 8,500 square feet, theoretically, you could divide it into two lots of 4,250 square feet each, which is well above the minimum.

2. **Setbacks and Building Requirements:** Anaheim may have specific setback requirements, which dictate how far structures must be from property lines. Typically, these are around 4 feet from side and rear property lines under SB-9, but check with Anaheim’s Planning Department for any specific rules.

3. **Parking Requirements:** Generally, SB-9 mandates one parking space per unit unless the property is within half a mile of public transit. Verify if your lot qualifies for this exemption.

### Owner Occupancy Requirement

SB-9 stipulates that the property owner must sign an affidavit stating they will occupy one of the housing units as their primary residence for at least three years
