Can I build two units under SB-9 in San Diego?

Hello and welcome to the exciting world of developing additional units under California’s SB-9! Navigating the intricacies of this law in San Diego can indeed be complex, but with the right guidance, you can maximize your property's potential. Let’s break down your query step-by-step:

### Understanding SB-9:

SB-9, effective January 1, 2022, aims to alleviate California’s housing crisis by allowing homeowners to split a single-family lot into two and build up to two units on each resulting parcel. This means potentially four units on what was once a single-family lot, subject to local regulations.

### Lot Split and Development in San Diego:

1. **Lot Split Requirements:**
- Under SB-9, you can split your 6,000 square foot lot into two parcels. Each resulting lot must be at least 1,200 square feet, and the split should be roughly equal in size (no less than 40/60 distribution).
- You must own the property for at least three years prior to applying for a lot split to prevent speculative developments.

2. **Building New Units:**
- Once split, you can build two units on each parcel. However, San Diego's local ordinances, zoning laws, and design standards will apply.
- Note that SB-9 mandates that the new units should not be used for short-term rentals; they must be rented for terms longer than 30 days.

3. **Local Zoning and Fees:**
- San Diego may have specific design standards for SB-9 developments, so consult the local Planning Department for detailed guidelines.
- Application fees for lot splits and building permits in San Diego can vary, but be prepared for costs in the range of $10,000 - $20,000 for the entire process, including surveys, planning applications, and potential environmental reviews.

4. **Parking Requirements:**
- SB-9 generally requires one parking space per unit unless the property is within half a mile of a major transit stop or in a designated urban infill area, which San Diego often qualifies for.
- Verify with San Diego’s local planning department if your lot qualifies for parking exemptions.

### Budgeting and Construction Costs:

1. **Construction Costs:**
- In San Diego, the cost of building ADUs or additional units generally ranges from $150 to $300 per square foot, depending on finishes and complexity. For a basic build, keeping each unit around 500-600 square feet might help you stay within your $300,000 budget for two units.
- Consider modular or prefab options, which might reduce costs and construction time.

2. **Timeline:**
- The timeline for permitting can take 3-6 months, with construction taking an additional 6-12 months, depending on the complexity and contractor availability.

### Tips and Common Mistakes:

1. **Engage with Professionals Early:**
- Hire a local architect or ADU consultant familiar with SB-9 developments in San Diego. Their expertise can be invaluable in navigating local regulations and optimizing design and cost.

2. **Utilities and Infrastructure:**
- Consider infrastructure upgrades like sewer, water, and electrical connections, which can add significant costs and should be factored into your budget from the start.

3. **Community and Environmental Concerns:**
- Be prepared for potential community pushback or environmental assessments, especially if your lot is in a sensitive area. Early engagement with neighbors and thorough environmental reviews can pre-empt these issues.

### Next Steps:

1. **Consult with San Diego’s Planning Department:**
- Before proceeding, visit or contact the San Diego Planning Department to discuss your specific lot, zoning, and any unique local restrictions or incentives.

2. **Research Financing Options:**
- Look into local and state programs that might offer financial assistance or favorable loan terms for SB-9 projects.

3. **Stay Informed:**
- Regulations can evolve, and staying updated on any changes in local ordinances or state laws regarding SB-9 is crucial.

By carefully planning and utilizing local resources, you can successfully navigate the SB-9 legislation and add value to your property while contributing to San Diego’s housing needs. Best of luck with your development, and feel free to reach out with more questions as you progress!
