Can I have multiple ADUs on one lot in Sacramento?

Hello,

Great to see your interest in developing ADUs on your property in Sacramento! With the recent legislative changes and the city’s push to encourage more ADU developments, Sacramento is indeed a promising place for your project. Let's break down your questions to help you move forward confidently.

### Number of ADUs on a Single Lot

In Sacramento, as per California state law (notably SB-9 and AB-68), property owners can build multiple ADUs. Generally, you can add one ADU and one Junior ADU (JADU) on a single-family lot. However, Sacramento’s specific city regulations may allow for more flexibility, especially with lots of your size. Given your 10,000 square feet lot, and considering the R-1 zoning, which typically allows for single-family residences, you might still be limited to these two additional units. However, it’s always worth consulting directly with the city’s planning department to explore any unique provisions or incentives they might have.

### Zoning Regulations in Sacramento

For properties like yours zoned as R-1, the addition of ADUs is generally permitted under Sacramento's updated zoning codes, aligned with state laws to facilitate ADU development. You should ensure that your ADUs comply with setback requirements, height limits, and lot coverage rules. Typically, ADUs cannot exceed 16 feet in height, and must maintain a four-foot setback from the rear and side property lines.

### Impact on Property Taxes and Utilities

Adding one or more ADUs will indeed affect your property taxes. While the base value of your lot remains unchanged, the value of the new structures will be added to the property’s assessed value. Expect an increase in taxes proportional to the construction cost, which could be approximately 1% of the construction cost per year.

Regarding utility connections, Sacramento’s utility connection fees have been reduced or waived in many cases for ADUs. However, this can vary based on the size and type of ADU. Speak with Sacramento's utility department to understand specific costs and any potential incentives or waivers that might apply.

### Construction Budget and Cost Considerations

For a budget of $200,000, you’re in a reasonable range for constructing a typical ADU in Sacramento. The cost of building an ADU can range from $150 to $300 per square foot, depending on the design, materials, and finishes. Assuming an average cost of $250 per square foot, you could potentially construct an 800 square foot ADU within your budget. However, always plan for a contingency of at least 10-15% for unexpected expenses.

### Permitting Process for Multiple ADUs

The permitting process in Sacramento is relatively streamlined compared to some other cities, thanks to state mandates to expedite ADU approvals. Typically, you should expect the process to take 60 to 90 days, depending on the complexity of your project and the current workload of the planning department.

To avoid common pitfalls:
- **Engage with a Local Architect or Designer:** They will ensure your plans comply with all local regulations and can help expedite the permit process.
- **Prepare a Comprehensive Application:** Include site plans, elevations, floor plans, and any other required documentation to avoid delays.
- **Communicate with Neighbors:** While not a regulatory requirement, keeping your neighbors informed can prevent disputes and foster goodwill.

### Next Steps and Resources

1. **Consult with Sacramento’s Planning Department:** They can provide precise details regarding your lot and any specific regulations or opportunities you might leverage.

2. **Hire a Professional:** An architect or contractor experienced with Sacramento ADUs can provide insights into cost-effective design and construction strategies.

3. **Explore State Resources:** The California Department of Housing and Community Development (HCD) offers guides and resources to aid in ADU development.

4. **Check Local Incentives:** Occasionally, Sacramento offers incentives for ADU construction, such as fee waivers or streamlined processes, particularly if your ADU will be used for affordable housing.

Building ADUs can be a great way to increase your property’s value and generate rental income, and with careful planning and expert advice, you can navigate the process smoothly. Best of luck with your project, and feel free to reach out if you have more questions!
