Our Attached ADU Construction Services

Building an attached ADU involves more than adding space—it requires careful integration with your existing home and alignment with Sacramento County requirements. Our services are structured to guide you through each stage, helping you create a functional, compliant, and purpose-driven living space whether for family use or rental income.

Custom Attached ADU Design

We design layouts that balance privacy, accessibility, and flow while aligning with how you actually plan to use the space. Whether you're building for family or rental purposes, we consider room placement, separate access, natural light, and daily usability from the start. From kitchens and bathrooms to sleeping areas and storage, every element is planned to feel like a natural extension of your home—not an afterthought.

Attached ADU Design-Build

Our design-build approach keeps everything under one roof, so you’re not juggling multiple contractors or dealing with miscommunication between design and construction teams. We handle planning, permitting, and building as one coordinated process. This results in clearer timelines, fewer delays, and a smoother experience from concept to completion.

Site Feasibility and Property Evaluation

Before any design begins, we evaluate your existing home and property conditions. This includes identifying the best attachment points, reviewing access options, and mapping out utility pathways. This step helps prevent costly surprises and ensures your project is realistic, code-compliant, and aligned with Sacramento County requirements.

Sacramento County Permit and Planning Coordination

Permitting can be one of the most stressful parts of an ADU project. We prepare permit-ready plans, review zoning and setback requirements, and manage submissions to local authorities. Our experience with Sacramento County processes helps minimize delays and keeps your project moving forward with fewer obstacles.

Structural Tie-In and Home Integration

Connecting a new ADU to your existing home requires careful structural planning. We manage framing connections, load distribution, and safe openings while ensuring the new addition blends seamlessly with your current structure. Exterior finishes, rooflines, and transitions are designed to match your home’s look and feel.

Utility Integration for Attached ADUs

We plan and coordinate all major utility connections, including plumbing, electrical, HVAC, and water/sewer systems. Our approach ensures the attached ADU functions independently where needed, while remaining efficient and properly integrated with your home’s infrastructure.

Interior Build-Out for Full Living Function

We complete every part of the interior build to create a fully livable unit. This includes kitchens, bathrooms, laundry areas, and comfortable living spaces. Materials and finishes are selected for durability, ease of maintenance, and long-term performance.

Attached ADUs for Family Living

For homeowners supporting aging parents, adult children, or caregivers, we design spaces that provide both proximity and privacy. Layouts can include accessible features, private entrances, and comfortable living arrangements that make day-to-day living easier for everyone.

Attached ADUs for Rental Income

If your goal is rental income, we focus on layouts that support independent living. This includes separate entrances, efficient kitchen and bathroom designs, and durable finishes that hold up over time. The result is a space that is practical for tenants and manageable for property owners.

Conversion-Based Attached ADU Solutions

Not every project requires building from the ground up. If your home has underused space—such as a large suite, wing, or enclosed area—we can convert it into a fully functional attached ADU. This approach can reduce construction time and complexity while still delivering a complete living unit.

Attached ADU Construction Process

A well-executed attached ADU project requires more than just construction—it requires coordination, planning, and a clear step-by-step approach. Our process is designed to reduce uncertainty, keep your project on track, and ensure every phase is handled with attention to detail from start to finish.

Step 1: Initial Consultation

We start by understanding how you plan to use your attached ADU—whether for family living, rental income, or long-term flexibility. We review your property, discuss your goals, and outline a realistic budget range so you have clarity from the very beginning.

Step 2: Site Review and Feasibility

We evaluate your home’s structure, layout, and possible attachment points. This includes access, available space, and utility considerations. The goal is to confirm what’s feasible on your property before moving into design.

Step 3: Concept Planning and Scope Development

We translate your goals into a practical layout. This includes defining room placement, entrances, and overall functionality. At this stage, we also align the scope with your budget and intended use.

Step 4: Design and Permit Preparation

We develop detailed plans and coordinate all required documentation for submission. This step ensures your project aligns with Sacramento County requirements and is ready for approval.

Step 5: Permitting and Pre-Construction

We manage the permitting process and handle any revisions required by local authorities. At the same time, we prepare for construction by finalizing scope, materials, and scheduling.

Step 6: Construction and Integration

We complete the full build, including structural tie-ins, utility connections, and interior finishes. Each phase is executed with attention to detail to ensure the new unit integrates seamlessly with your home.

Step 7: Final Walkthrough

Once construction is complete, we walk through the finished ADU with you to ensure everything meets expectations and is ready for use, whether for family or tenants.
