Our ADU Design & Construction Services in riverside

At ADUs by Avatar, we provide complete design-build ADU services for homeowners throughout Riverside and the surrounding Inland Empire. Our team manages the entire process from the initial feasibility review through final construction so homeowners have a clear and organized path to building their ADU.

ADU Assessment & Property Evaluation

Every property is different. We will review your property to determine what type of ADU may be possible based on zoning, lot size, setbacks, access, utilities, and local regulations.

During this stage we evaluate:

• Lot size and layout
• Zoning and ADU eligibility
• Utility access and connections
• Parking considerations
• Potential ADU size and placement

Custom ADU Design

Once feasibility is confirmed, we work with homeowners to create custom ADU designs that fit both the property and the homeowner’s goals.

Design services include:

• Custom floor plan development
• Detached ADU layouts
• Garage conversion design
• Attached ADU design
• Space planning and functionality
• Exterior design to match the existing home

Our goal is to design an ADU that maximizes both livability and property value.

ADU Permits & City Approvals

Navigating city requirements can be one of the most challenging parts of building an ADU. Our team helps guide the permitting process to help ensure your project meets local planning and building department requirements.

This process includes:

• Preparing permit-ready plans
• Submitting plans to the city
• Responding to plan check comments
• Coordinating with city departments
• Managing approvals required before construction

Detached ADU Construction

Detached ADUs are separate backyard homes built on the same property as the main residence. These units provide privacy and flexibility for rental income, family housing, or guest space.

Our team handles:

• Site preparation
• Foundation work
• Framing and structural construction
• Roofing and exterior finishes
• Plumbing, electrical, and HVAC
• Interior construction and finishes

Garage Conversions

Garage conversions are one of the most popular ways to add an ADU because the structure already exists.

We help homeowners convert existing garages into comfortable living spaces by handling:

• Structural upgrades
• Insulation and drywall
• Plumbing installation
• Electrical upgrades
• Kitchens and bathrooms
• Interior finishes

Garage conversions can often be one of the most cost-effective ADU options.

Full Design-Build Project Management

Building an ADU involves many steps and trades. Our design-build approach helps streamline the process by coordinating the entire project through one team.

We manage:

• Scheduling and construction timelines
• Subcontractor coordination
• Inspections and quality control
• Communication throughout the project

This helps homeowners move from concept to completed ADU with fewer complications.
