Can I have multiple ADUs on one lot in San Diego?

Hi there,

Thanks for reaching out with your question! I’m glad to see you’re considering maximizing your property’s potential with ADUs. San Diego, like much of California, has been working to make it easier for homeowners to add ADUs, but there are still some specifics to navigate.

### Can You Have Multiple ADUs?

Yes, you can have more than one ADU on your property in San Diego, especially given your sizable 10,000-square-foot lot. California state laws such as SB-9 and AB-68 have greatly relaxed restrictions around ADUs. According to these laws, you can generally have:

1. **One Standard ADU**: This can be a detached or attached unit.
2. **One Junior ADU (JADU)**: A JADU must be created within the existing footprint of the primary residence and can be up to 500 square feet.

Given your lot size and zoning, you might be able to build both a detached ADU and a JADU, depending on specific local zoning ordinances.

### Zoning Considerations

For Clairemont and much of San Diego, the zoning will determine the exact possibilities. Most residential zones will allow at least one detached ADU and one JADU. Since you’re in Clairemont, check the specific zoning of your property through the San Diego Development Services Department (DSD).

### Parking Requirements

California state law has reduced parking requirements for ADUs significantly. If your property is within a half-mile of public transit, no additional parking is required for the ADU. In other cases, typically, one additional parking space per ADU might be required unless exemptions apply (e.g., converting existing garages).

### Budgeting and Costs

You mentioned a budget of $150,000 per ADU. This is feasible but tight, especially in San Diego, where construction costs can be high. Here’s a rough breakdown:

- **Design and Permitting**: $5,000 to $15,000
- **Construction Costs**: $150 to $250 per square foot, depending on the finishes and complexity.
- **Utilities and Site Prep**: $10,000 to $30,000

Given these ranges, a 500-square-foot ADU could cost between $75,000 to $125,000, with a 750-square-foot unit potentially costing $112,500 to $187,500. You might need to adjust your budget or simplify designs to stay within your limits.

### Incentives and Programs

San Diego offers some incentives for ADU construction, including permit fee reductions and expedited processing. The city’s **Affordable ADU Bonus Program** allows for increased density and additional units if you agree to rent your ADUs at affordable rates.

### Steps to Get Started

1. **Research Local Zoning**: Confirm your zoning and what’s permissible through San Diego DSD.
2. **Consult with an Architect/Designer**: They can help maximize space and design cost-effective structures.
3. **Budget Planning**: Get multiple quotes from contractors to ensure your budget aligns with your goals.
4. **Permitting**: Submit plans to the DSD for review. Thanks to California’s streamlined processes, this can be faster than before, but expect it to take 3 to 6 months.
5. **Construction**: Once permits are approved, construction can take anywhere from 6 to 12 months, depending on the complexity of the build and contractor availability.

### Tips and Warnings

- **Utilities**: Plan for the cost and logistics of connecting utilities. This can be a hidden cost that surprises many homeowners.
- **Hire Experienced Contractors**: Ensure your contractor has experience with ADUs in San Diego to avoid common pitfalls.
- **Neighbor Considerations**: Engage with neighbors early to mitigate any concerns about construction or increased density.

### Resources

- **San Diego Development Services**: [sandiego.gov/development-services](https://www.sandiego.gov/development-services)
- **California ADU Handbook**: This provides a comprehensive overview of state laws.
- **Local ADU Workshops**: Check for workshops or seminars hosted by local planning departments or housing advocates.

In conclusion, while the process can seem daunting, San Diego provides a relatively ADU-friendly environment. With careful planning and adherence to local and state regulations, you can successfully add multiple ADUs to your property. Good luck with your project, and feel free to reach out if you have further questions!
