ADU Design Tips for Roseville Homeowners

ADU Design Tips for Roseville Homeowners

Thinking about building an Accessory Dwelling Unit (ADU) on your property in Roseville? Whether you're adding a rental, guest house, or space for family, ADUs are one of the most popular ways to boost property value and maximize your lot. But before you start drafting plans, there are a few things you should know about designing an ADU that gets approved quickly in Roseville.

Understand Roseville’s Zoning & Setbacks

The City of Roseville allows both attached and detached ADUs, but they have specific rules about:

• Setbacks: Typically 4 feet from side and rear property lines
• Maximum size: Usually up to 1,200 sq. ft., depending on your lot size
• Height limits: 16 feet for single-story, more with stepbacks
• Lot coverage: Your ADU must stay within the total allowable buildable area

Before designing your ADU, it’s important to confirm your zoning designation and lot layout. Some properties in Roseville also fall under HOA or design review restrictions.

Keep It Simple to Save Time

The fastest ADUs to permit in Roseville are simple, single-story designs with straightforward layouts. Complicated rooflines, odd shapes, or second-story units usually take longer in plan review and may trigger additional engineering or neighborhood review.

We recommend starting with a clean rectangular footprint and focusing on maximizing interior layout, natural light, and privacy from the main home.

Plan Ahead for Utilities & Access

Roseville requires ADUs to have independent living features — meaning kitchen, bathroom, and private entry. Think about:

• Where will the ADU connect to sewer, water, and power?
• How will a fire department access the structure?
• Is there a clear path from the street or driveway?

Including these considerations early in your design will make your plan set cleaner and help you avoid costly changes during plan check.

You’ll Need These Plans for Submittal

A typical ADU plan set in Roseville includes:

• Site Plan (with setbacks, utility locations, and lot lines)
• Floor Plan (with dimensions, fixtures, and layout)
• Roof Plan & Elevations
• Electrical Plan
• Title 24 Energy Compliance documentation
• Structural Plans (if required)

The city is strict about formatting and scale — which is why working with a local drafter who knows what Roseville expects can save you weeks of back-and-forth.
