What's the ideal size for an ADU in Sacramento?

Hi there,

Congratulations on taking the exciting step towards building an ADU (Accessory Dwelling Unit) in Sacramento! As someone who's navigated the complexities of ADU projects in California, I'm here to provide you with detailed guidance tailored to your needs and local regulations.

**1. Determining the Ideal Size for Your ADU:**

In Sacramento, you can indeed build an ADU up to 1,200 square feet. However, determining the right size involves balancing your budget, lot size, and intended use. Given your 7,500 square foot lot, a 1,200 square foot ADU could fit comfortably, but may not be the most cost-effective choice if you're aiming to keep costs under $150,000.

**Budget Considerations:** Typically, construction costs for ADUs in Sacramento range from $200 to $300 per square foot. A 1,200 square foot ADU could thus cost between $240,000 and $360,000, significantly exceeding your budget. To stay within your $150,000 budget, consider a smaller unit around 500 to 600 square feet, which could cost between $100,000 and $180,000.

**2. Property Tax Implications:**

In California, adding an ADU will increase your property taxes, but only based on the value of the new construction, not the entire property. For example, if your ADU adds $150,000 in assessed value, expect property taxes to increase by roughly 1.1% of that amount annually, or about $1,650.

**3. Rental Income Potential:**

When considering rental income, a smaller ADU might appeal to singles or couples, while larger units can attract families willing to pay higher rent. In Sacramento, a well-designed 600 square foot ADU can fetch between $1,500 to $2,000 per month, depending on location and amenities. Larger units could command more, but also come with higher upfront costs.

**4. Design Considerations and Regulations:**

- **Local Ordinances:** Sacramento's zoning laws are generally favorable towards ADUs. Under SB-9 and AB-68, your ADU can bypass certain density restrictions, and you won't need additional parking if your property is within half a mile of public transit.

- **Design Tips:** Focus on maximizing space efficiency with open floor plans and multifunctional areas. Consider energy-efficient designs to reduce long-term costs and appeal to eco-conscious tenants. Also, ensure compliance with Title 24, California's building energy efficiency standards.

**5. Actionable Steps:**

- **Consult with Experts:** Engage with local architects or ADU specialists familiar with Sacramento's permitting process. They can provide invaluable insights into cost-saving designs and materials.

- **Permitting Process:** Plan for a timeline that includes about 3-6 months for design and permits, and another 6-9 months for construction. Sacramento's streamlined ADU approval process often facilitates quicker permitting than other cities.

- **Choose Quality Materials Wisely:** While staying within budget, don't compromise on key quality features that boost longevity and tenant satisfaction, such as durable flooring and energy-efficient windows.

**6. Common Pitfalls to Avoid:**

- **Underestimating Costs:** Always include a 10-15% contingency in your budget for unexpected expenses.
- **Overlooking Utility Connections:** Ensure early assessment of utility connections, as these can sometimes lead to costly surprises.
- **Ignoring Local Resources:** The City of Sacramento offers resources and workshops on ADU development—take advantage of these.

**7. Next Steps and Resources:**

- Visit the [City of Sacramento's Planning Division](https://www.cityofsacramento.org/Community-Development/Planning) for ADU guidelines and resources.
- Consider reaching out to the Sacramento chapter of the American Institute of Architects for recommendations on reputable local architects.

Building an ADU is a significant investment, but with careful planning and the right team, it can enhance your property's value and provide a source of income. Feel free to reach out if you have more questions or need further assistance. Best of luck on your ADU journey!
