What's the ADU approval process like in San Francisco?

Hello there!

Embarking on the journey of building an ADU in San Francisco is an exciting opportunity to maximize your property’s value and functionality. Given your location in the Richmond District and your budget, it’s crucial to navigate the approval process with a clear understanding of the local regulations and requirements. Let’s break down your questions to give you a clearer path forward.

### Fast-Track Permits

San Francisco does offer a streamlined permit process for ADUs, often referred to as the "ADU Fast Track Program." To qualify, your project must meet certain criteria. Generally, your ADU should be a conversion of existing space (like a garage or basement) or a new construction that adheres to zoning and building codes without requiring significant variances. The fast-track process is designed to expedite projects that conform to these straightforward parameters, reducing the review period.

**Criteria for Fast-Track:**
1. **Zoning Compliance**: Your project must comply with local zoning ordinances. Since you're in the Richmond District, a typical residential area, check that your ADU plans align with RH-1 (Residential, House, One-Family) zoning regulations.
2. **Existing Structure Conversion**: Projects that involve converting existing structures are more likely to qualify.
3. **No Variances Required**: The project should not need variances or exceptions to zoning rules.

### Setbacks and Height Limits

San Francisco has specific regulations regarding setbacks and height limits, which can be quite strict, especially in densely populated areas. For detached ADUs, typical requirements include:
- **Rear Yard Setback**: Generally, you'll need a rear-yard setback of 4 feet.
- **Side Yard Setback**: Usually a 4-foot minimum.
- **Height Limit**: Detached ADUs typically have a height limit of 16 feet.

However, given the compact nature of San Francisco lots, it’s often possible to apply for exceptions if you can demonstrate that the ADU won’t impact neighbors’ privacy or access to light. Working with a knowledgeable architect familiar with local codes can help maximize your design within these constraints.

### Permitting Timeline

The timeline for obtaining permits in San Francisco varies. For a fast-track application, you could expect the process to take between 3 to 6 months. If your project requires more extensive review or variances, this timeline can extend up to 12 months or more. It's important to be prepared for potential delays, which are not uncommon due to the city's high volume of building applications and complexity of local regulations.

### Costs and Fees

Your budget of $200,000 is a reasonable starting point for an ADU in San Francisco, but it’s wise to anticipate additional costs:
- **Permit Fees**: Expect to pay between $5,000 to $10,000 for permits and inspections.
- **Impact Fees**: These can vary, but typically range from $4,000 to $12,000, depending on the size and scope of your ADU.
- **Design and Engineering Fees**: Plan to allocate around 10-15% of your total budget for architectural and engineering services.

**Unexpected Costs**: Be mindful of potential costs related to utility connections, especially if your existing systems need upgrading to accommodate the new unit. Soil tests and mitigation, if required, can also add unexpected expenses.

### Regulations and Laws

Several state laws such as California’s SB-9 and AB-68 have been enacted to facilitate the construction of ADUs by easing restrictions and streamlining approvals. These laws generally override local ordinances that are overly restrictive, so it's beneficial to familiarize yourself with them. However, local rules still apply, so your project must comply with San Francisco’s specific ordinances.

### Next Steps

1. **Consult with a Professional**: Engage with a local architect or ADU specialist who understands San Francisco’s unique building landscape. They can provide invaluable insights and help streamline the design and permitting process.
2. **Visit the San Francisco Planning Department**: Their staff can offer guidance specific to your property and help identify potential hurdles early on.
3. **Neighbors and Community**: Engage with your neighbors early in the process to discuss your plans. This can help mitigate any concerns and facilitate a smoother approval process.

### Final Tips

- **Documentation**: Keep meticulous records of all communications and documents submitted to the city.
- **Stay Informed**: Regularly check for updates from the San Francisco Planning Department to stay abreast of any changes in the ADU regulations.
- **Contingency Fund**: Maintain a contingency fund of at least 10-15% of your budget to cover unforeseen expenses.

Building an ADU in San Francisco is a complex but rewarding venture. With careful planning, professional guidance, and a clear understanding of the process, you’ll be well on your way to adding a valuable asset to your property. Good luck with your project!
