Can I have multiple ADUs on one lot in Santa Ana?

Hello,

It's great that you're considering adding ADUs to your property in Santa Ana. Given California's recent legislative push to encourage ADU development, you're on the right track for maximizing your property's potential. Here’s a detailed breakdown of what you need to know and consider:

### Multiple ADUs in Santa Ana: Regulations and Possibilities

**1. Understanding Local Regulations:**

In California, state laws such as SB-9 and AB-68 have indeed made it easier to add ADUs. However, local jurisdictions like Santa Ana can impose additional regulations. Generally, the state allows for a primary residence plus one ADU and one Junior ADU (JADU) on a single lot.

In Santa Ana, you can typically build:
- **One detached ADU**
- **One Junior ADU (JADU)** within the existing structure of the primary dwelling.

Given your lot size of 10,000 square feet, there might be additional flexibility. However, it’s crucial to check the specific zoning of your property. Santa Ana’s zoning code can sometimes have area-specific restrictions, so visiting the Planning and Building Agency or reviewing their online resources would be a wise first step.

**2. Budget Considerations:**

With a budget of $150,000, constructing two smaller ADUs (one being potentially a JADU) is feasible, though it will require careful planning and budgeting. Here's a rough breakdown of potential costs in Santa Ana:

- **Design and Permits:** $5,000 - $15,000
- **Construction Costs:** $100,000 - $150,000 for a detached ADU, depending on size and finishes
- **Utility Connections:** $5,000 - $10,000
- **Landscaping and Site Prep:** $5,000 - $15,000

Given these numbers, you might aim for a modest detached ADU (around 500-600 sq ft) and a JADU for maximizing your budget.

### Design and Infrastructure Considerations

**1. Utility Hookups:**

- **Water and Sewer:** Ensure you have the capacity to support additional units. This often involves extending existing lines, which can be a significant expense if your current setup is inadequate.
- **Electrical:** You may need to upgrade your main electrical panel to accommodate additional load.
- **Gas:** If your ADUs will use gas, consider the cost of extending gas lines.

**2. Parking Requirements:**

The state has relaxed parking requirements if your property is near public transit. However, Santa Ana might still have specific requirements, so verify whether you need to provide additional parking spaces. Often, the presence of a driveway or garage can suffice.

### Permitting and Construction Timeline

**1. Timeline:**

- **Design and Permitting:** 3-6 months. This includes working with an architect or designer, submitting plans, and receiving approval from the city.
- **Construction:** 6-12 months, depending on the complexity and size of the ADUs.

Expect the entire process, from conception to completion, to take roughly 12-18 months.

### Tips and Common Mistakes

**1. Engage with Professionals Early:**
Hire an experienced architect or designer familiar with Santa Ana’s ADU regulations. They can help navigate zoning codes and streamline the permit process.

**2. Neighbor Relations:**
Communicate with your neighbors about your plans. This can help prevent complaints or issues during the construction phase.

**3. Verify Local Ordinances:**
Double-check any local amendments to state laws. Santa Ana might have specific requirements or incentives.

### Next Steps

1. **Visit Santa Ana’s Planning and Building Agency:** In-person visits can provide clarity on specific zoning and permitting requirements.

2. **Consult with an ADU Specialist or Architect:** They can offer personalized advice based on your property specifics.

3. **Explore Financing Options:** Consider home equity loans, construction loans, or state programs that might offer funding for ADU projects.

4. **Community Resources:** Check out local workshops or forums on ADU development. These can offer insights and connect you with professionals and other homeowners who have navigated this process.

By following these steps and considering local regulations, you’ll be well on your way to successfully adding ADUs to your property in Santa Ana. Best of luck with your project!
