Can I use a prefab ADU in Sacramento?

Hello,

It's exciting to hear about your interest in adding a prefab ADU to your property in Sacramento. Prefab ADUs can indeed be a cost-effective and efficient solution, but there are several factors to consider. Let's break down your queries to help you make an informed decision.

### Zoning Laws and Regulations

In Sacramento, like many parts of California, recent laws such as SB-9 and AB-68 have made it easier to add ADUs by overriding some local restrictions. These laws aim to increase housing availability and allow for more flexibility in adding units like ADUs. Generally, Sacramento permits one ADU and one Junior ADU (JADU) per single-family lot. Given your lot size of over 8,000 square feet, you are likely in a good position to add an ADU, assuming you comply with setbacks and other local zoning requirements.

For zoning, Sacramento typically requires a minimum setback of four feet from side and rear property lines for ADUs. Additionally, your total lot coverage, including the primary dwelling and the ADU, should not exceed 40-50%, depending on the zoning district. It's advisable to consult the Sacramento Planning Division to confirm specific zoning codes applicable to your property.

### Permitting Process

For prefab ADUs, the permitting process is somewhat simplified compared to traditional builds due to standardized designs that often pre-approve certain elements. However, you will still need to obtain a building permit. The process involves submitting site plans, elevation drawings, and sometimes a landscape plan.

The fees for permits can range from $5,000 to $10,000, depending on the complexity of your project and whether any variances are required. Generally, the timeline for receiving permits can take anywhere from 4-8 weeks, although this can extend during peak building seasons.

### Utility Connections

Connecting utilities for a prefab ADU can be straightforward, but it requires proper planning. The complexity largely depends on your existing utility setup. For water and sewer connections, you might need to extend lines from the main house, which can cost between $3,000 and $8,000, depending on the distance and landscape challenges.

Electrical connections are usually simpler, with costs ranging from $1,500 to $3,000. However, if your current electrical panel cannot support the additional load, you may need an upgrade, which can add another $1,000 to $3,000 to your budget.

### Local Suppliers and Contractors

Sacramento has several contractors specializing in prefab ADUs. Companies like Connect Homes and Plant Prefab are well-regarded for their efficient designs and service. It's beneficial to get multiple quotes and check contractor references to ensure you're getting the best value and quality for your project.

### Cost and Timeline

For a prefab ADU in Sacramento, you're looking at a cost range of $70,000 to $150,000, depending largely on size, finishes, and utility complexities. This includes the unit itself, site preparation, utility hookups, and permits. Your $100,000 budget is feasible, especially if you prioritize essential finishes and keep customization to a minimum.

As for timelines, from initial planning to completion, expect the project to take anywhere from 6 to 12 months. This includes design and planning, permitting, site preparation, installation, and final inspections.

### Helpful Tips

1. **Consult with the City Early**: Engage with Sacramento's Planning and Development Department early in your planning. They can provide guidance specific to your property and help you avoid common pitfalls.

2. **Consider Financing Options**: Look into financing options such as home equity loans or specialized ADU loans, which some local credit unions and banks offer.

3. **Think About Future Needs**: Consider the long-term use of your ADU. Opt for designs that allow flexibility in usage, whether for rental, family use, or as an office space.

4. **Avoid Common Mistakes**: Ensure proper site drainage and plan for adequate access for installation. Also, check if your neighborhood has any homeowners association (HOA) restrictions.

### Next Steps

- **Site Evaluation**: Conduct a thorough site evaluation with a professional to assess feasibility.
- **Plan Submission**: Prepare your plans and budget, then submit your permit application.
- **Research Contractors**: Get quotes and timelines from at least three different prefab ADU providers.
- **Utility Assessment**: Have a utility assessment done to plan for connections.
