1. Understanding ADU Permits in Roseville

Before applying for a permit, it’s important to know what type of ADU you’re planning:

Detached ADU – A standalone unit in your backyard.
Attached ADU – An addition to your existing home (e.g., basement or garage conversion).
Junior ADU (JADU) – A smaller unit (up to 500 sq. ft) within the primary home.

Each type has different requirements, so confirming your project’s scope early will streamline the permitting process.

2. Step 1: Check Zoning and Feasibility

Roseville has specific zoning laws that dictate where and how ADUs can be built. Key considerations include:

Property Size & Setbacks – Minimum distances from property lines.
Maximum ADU Size – Typically 1,200 sq. ft for detached units.
Parking Requirements – Some ADUs may need additional parking spaces.

Before investing in plans, verify that your property meets these standards. ADU Builders Placer can help assess your lot and ensure compliance.

3. Step 2: Prepare Your ADU Plans

To submit for a permit, you’ll need detailed construction plans, including:

Site plans showing property lines and setbacks.
Floor plans with dimensions.
Elevation drawings (for detached ADUs).
Utility connections (water, sewer, electrical).

Tip: Roseville offers pre-approved ADU plans, which can speed up approval. If you’re working with a design-build firm like ADU Builders Placer, they’ll handle this step for you.

4. Step 3: Submit Your Permit Application

Once your plans are ready, submit them to the City of Roseville Planning Department. Required documents typically include:

Completed permit application.
Construction drawings.
Proof of property ownership.
Fees (varies based on ADU size and type).

Processing Time: Under California law, ADU permits must be reviewed within 60 days if they meet all requirements.

5. Step 4: Address Plan Check Comments

After submission, the city will review your application and may request revisions. Common corrections include:

Adjusting setbacks or height limits.
Clarifying utility connections.
Updating fire safety measures.

Working with an experienced builder can minimize delays at this stage.

6. Step 5: Receive Approval & Begin Construction

Once approved, you’ll receive your ADU permit and can start construction. Key reminders:

Inspections Required – The city will inspect at various stages (foundation, framing, final).
Stay Compliant – Any changes to the approved plans may require re-review.

7. Common ADU Permit Challenges & How to Avoid Them

Delays Due to Incomplete Plans – Ensure all drawings meet city standards before submitting.
