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

Hello there!

I’m glad to see your interest in developing multiple ADUs in San Diego, particularly in the vibrant North Park area. The good news is that San Diego is indeed encouraging the development of ADUs, and under the right circumstances, you can have more than one on a single lot. Let's break this down comprehensively:

### Can You Build Multiple ADUs?

**State and Local Regulations:**

1. **State Law (SB-9 and AB-68):** California state laws, like SB-9 and AB-68, have significantly relaxed the restrictions on building ADUs. These laws facilitate the construction of multiple ADUs by allowing for the creation of up to two ADUs on a single-family lot, and in some cases, conversion of existing structures into ADUs.

2. **City of San Diego Regulations:** San Diego's local regulations align with state laws but also offer additional flexibility. As of the latest updates, you can generally build one detached ADU and one Junior ADU (JADU) per property. However, due to recent amendments, larger lots like yours may allow for more flexibility, especially if you’re considering converting existing structures.

### Key Considerations:

1. **Lot Size and Zoning Restrictions:** With a lot over 10,000 square feet, you have a good potential for adding multiple units. San Diego’s zoning ordinances now allow up to two detached ADUs on larger lots, provided they meet specific setback and coverage requirements.

2. **Parking Requirements:** San Diego has relaxed parking requirements for ADUs, especially if your property is within half a mile of public transit. If not, typically, you need to provide one parking space per ADU, but this can vary depending on the specifics of your lot and neighborhood.

3. **Utility Connections:** New ADUs typically require separate utility hookups, which can add to costs. However, the city often waives impact fees for ADUs under 750 square feet which might mitigate some of these costs.

### Cost and Timeline:

1. **Cost Estimates:** For San Diego, construction costs for ADUs generally range from $150 to $300 per square foot, depending on the complexity and finishes. With a $300,000 budget, you’re looking at roughly two 500-square-foot ADUs at the higher end of the cost spectrum.

2. **Timeline:** Permitting can take anywhere from 3 to 6 months, depending on the complexity of the project and the thoroughness of your initial application. Construction might take an additional 6 to 12 months. Start with a pre-application meeting with the city to get a more accurate timeline tailored to your project.

### Process and Permits:

1. **Initial Consultation:** Engage with an architect or a designer experienced in ADUs in San Diego. They can help navigate local zoning laws and design your units efficiently.

2. **Pre-Application Meeting:** This meeting with the San Diego Development Services Department can clarify any potential issues and streamline your application process.

3. **Permit Submission:** Submit detailed plans for review. Ensure they include site plans, floor plans, elevations, and any necessary engineering reports.

4. **Inspections and Compliance:** Throughout construction, expect several inspections to ensure compliance with building codes and safety standards.

### Tips and Warnings:

- **Maximize Efficiency:** Work with your architect to design space-efficient units that maximize livability while staying within budget and regulatory constraints.

- **Stay Informed on Local Ordinances:** Zoning laws can change. Keep abreast of any updates from the San Diego Development Services Department.

- **Common Mistakes:** Avoid starting construction without permits, as this can lead to fines and mandatory demolition.

### Next Steps and Resources:

1. **Contact Local Experts:** Consider hiring a local ADU consultant or architect who can provide insights specific to North Park.

2. **Visit the San Diego Development Services Website:** They have a wealth of resources, including checklists and guides for ADU development.

3. **Connect with Other Homeowners:** Local forums or neighborhood groups can provide firsthand insights and referrals for contractors and designers.

By navigating the regulatory landscape and planning carefully, you can successfully add multiple ADUs to your property, enhancing both its utility and value. Good luck with your project in North Park, and feel free to reach out if you have further questions!
