A Step-by-Step Guide to Adding a Junior Accessory Dwelling Unit (JADU) in Santa Rosa, CA

Have you seen the new VESSEL modular home at the corner of Fulton Rd. and River Rd. in Santa Rosa? These could be a great option for a detached unit. Junior ADUs (Accessory Dwelling Units) are attached. Read below to learn more about them.

As a local real estate expert here in Santa Rosa, I’ve seen firsthand how adding a Junior Accessory Dwelling Unit (JADU) can significantly boost a property’s value. Time and time again, I’ve witnessed homeowners reap the financial rewards of this investment while also enjoying the practical benefits it provides. Whether you’re looking to create a rental opportunity or house a family member, a JADU is a fantastic way to make the most of your space. Here’s my personal guide to navigating the process.

1. Understand What Is A JADU

is essentially a compact living unit, up to 500 square feet, that’s created within the walls of your existing or planned single-family home. This can include converted spaces like attached garages. Each JADU needs to have an efficiency kitchen and its own separate entrance. The best part? It can share a bathroom with the main house. Just keep in mind that owner occupancy is required—you’ll need to live in either the main home or the JADU.

2. Check Zoning and Development Standards

The first thing I always tell my clients is to verify that their property’s zoning allows for a JADU. In Santa Rosa, this is typically allowed on lots zoned for single-family residences. It’s also important to be aware of local development standards like setbacks, height restrictions, and lot coverage. These will shape what’s possible for your property.

3. Prepare Plans and Documents

Documentation is key, and trust me, being thorough here saves headaches down the line. You’ll need:

Site Plan: This shows the layout of your property, including where the JADU will be located.
Floor Plan: Outlines the interior of the unit.
Foundation Plan, Construction Details, and Elevations: Required for any new structures.
Deed Restriction: A Declaration of Restrictions of Occupancy to confirm compliance with owner-occupancy rules.

4. Submit Your Application

Once your plans are ready, it’s time to submit a Building Permit Application to the City of Santa Rosa’s Planning & Economic Development Department. You can email everything to permitsubmittal@srcity.org. After submitting, the city will contact you about the application fee. I always recommend double-checking that all documents are complete before submitting to avoid delays.

5. Application Review

The city typically reviews applications within 60 days. If there are any issues, they’ll send feedback outlining what needs to be fixed. Once everything is approved, you’ll get the permits needed to start construction.

6. Begin Construction

With permits in hand, you’re ready to build. Whether you’re hiring a contractor or doing it yourself, make sure the work complies with local building codes. The city will conduct inspections at various stages of the project.

7. Final Inspections and Occupancy

When construction is complete, schedule a final inspection through Santa Rosa’s Automated Building Permit Inspection Request System. Once you pass, your JADU is officially ready for use!

My Pro Tips

Consult the Pros: I always advise working with architects and contractors who are experienced with local regulations. They can save you a lot of time and hassle.
Use Available Resources: The City of Santa Rosa’s website is packed with tools like the ADU Process Map and Application Checklist—don’t overlook them.
Think Financially: JADUs are an investment. I’ve seen how they can dramatically increase a property’s market value while providing ongoing benefits like rental income. It’s a win-win scenario for any homeowner.

Adding a JADU to your home is a rewarding project that provides both personal and community benefits. However, I encourage you to verify any and all information with the City of Santa Rosa, as requirements and regulations can change. If you're unsure about whether a JADU is the right move for you, or if you're contemplating whether to move instead, I’m here to help you weigh the pros and cons of each option. I’d be happy to provide personalized advice. Let’s work together to make your vision a reality!
