How much yard space do I need for an ADU in Santa Clarita?

Hello,

It's great to hear that you're considering adding an ADU to your property in Santa Clarita! I'll do my best to guide you through the process with information that's both practical and specific to your situation.

### Yard Space and Setbacks

Firstly, when it comes to yard space for an ADU in Santa Clarita, the city follows California's state-mandated guidelines, which have been designed to encourage the development of ADUs. There's no minimum lot size requirement per se; instead, the focus is on compliance with setback requirements and ensuring the ADU fits comfortably within your existing property layout.

For Santa Clarita:
- **Setbacks:** Typically, you'll need to maintain a minimum setback of 4 feet from the rear and side property lines. The front setback usually follows the same requirements as the primary dwelling, which can vary, so it's best to check with the city's planning department.
- **Separation:** If the ADU is detached, a minimum distance (often around 6 feet) from the main dwelling is generally required.

Given your 8,500 square feet lot, you should have ample space to work with these requirements, assuming your main house and any other existing structures allow for it.

### Budget Considerations

With a budget of $150,000, your project is quite feasible, especially if you're considering a one-bedroom unit. In Santa Clarita, construction costs for ADUs can range from $150 to $300 per square foot, depending on finishes and complexity. A modestly designed 500-square-foot one-bedroom ADU could fit well within your budget if planned carefully.

### Parking Requirements

Under California state law (referencing AB-68 and SB-9), parking requirements for ADUs have been relaxed significantly:
- **Parking Waivers:** If your property is within half a mile of public transit, no additional parking is required. Given your location, it's worth checking if this waiver applies. Alternatively, if your ADU converts existing structures, like a garage, additional parking may not be required.
- **Standard Requirement:** If a waiver does not apply, typically one parking space per ADU is required, which can often be tandem space on your existing driveway.

### Size Recommendations

For a one-bedroom ADU, a size between 400 and 600 square feet is generally comfortable and cost-effective. This size offers a good balance between livability and budget, especially considering construction costs.

### Local Considerations and Common Mistakes

- **Permitting:** Always start with a visit to the Santa Clarita Planning Division. They can provide guidance specific to your parcel and any unique zoning considerations. Remember, permits are essential before starting construction.
- **Utilities:** One common oversight is underestimating the cost and complexity of connecting utilities. Ensure you budget for water, sewer, and electrical connections, which can sometimes add unexpected costs.
- **Design Efficiency:** Work with a designer experienced in ADU projects to maximize space efficiency. Modular designs and pre-approved plans can also save time and money.

### Next Steps

1. **Preliminary Planning:** Sketch a rough layout considering setbacks and existing structures. This will help when consulting with professionals.
2. **Consult Professionals:** Engage with an architect or ADU specialist to refine your design and develop a detailed plan.
3. **Budgeting and Financing:** Explore financing options if needed. Some local credit unions offer ADU-specific loans.
4. **Permitting Process:** Submit your designs to the Santa Clarita Planning Division for review. This can take several weeks, so plan accordingly.
5. **Construction:** Once permits are approved, hire a reputable contractor. A typical ADU project might take 6-12 months from start to finish.
