Our Detached ADU Construction Services

Building a detached ADU involves more than just construction—it requires coordinated planning, clear decision-making, and a process that removes uncertainty at every stage. Our services are designed specifically for Sacramento County homeowners who want a straightforward path from idea to completed backyard unit.

From evaluating your property to managing design, permits, and construction, each service is structured to address common concerns like feasibility, cost clarity, timeline expectations, and compliance. This ensures your project moves forward efficiently while delivering a functional and long-lasting living space.

Site Feasibility Review and Property Assessment

We begin by evaluating your property to determine if and how a detached ADU can be built. This includes reviewing lot size, placement options, access points, setback considerations, and utility pathways.

This step provides clarity early in the process and helps prevent costly redesigns by identifying limitations, opportunities, and realistic build scenarios from the start.

Detached ADU Design and Floor Plan Planning

We design your detached ADU based on how you intend to use the space. Whether you are building for rental income, family housing, or flexible use, we focus on efficient layouts, privacy, and practical flow.

Every design decision is tied to usability—ensuring the unit feels livable, functional, and aligned with your long-term needs rather than just fitting within a footprint.

Structural Engineering and Construction Documents

We prepare detailed, build-ready plans that support a smooth construction process. This includes structural layouts, foundation planning, and technical documentation required for both approvals and execution.

Proper engineering reduces the risk of construction issues, unexpected changes, and delays once the project begins.

Detached ADU Permitting and Submittal Coordination

We manage the permitting phase by organizing documentation, coordinating submissions, and addressing review comments. This process is often one of the most confusing parts for homeowners, and structured handling helps keep the project moving.

Our goal is to simplify approvals and reduce back-and-forth by preparing plans that are aligned with expected requirements from the beginning.

Site Preparation and Foundation Work

Before construction begins, we prepare the site by clearing, grading if necessary, and establishing a stable foundation. This phase sets the groundwork for everything that follows.

Proper site preparation ensures structural stability and helps avoid issues that could impact the build later.

Full Detached ADU Construction

We manage the entire construction process under one coordinated system. This includes framing, roofing, exterior finishes, windows, interior build-out, kitchen and bathroom installation, flooring, and final detailing.

By handling all phases together, you avoid the complexity of managing multiple contractors and maintain consistency in quality, timeline, and execution.

Utility Planning and Connection Coordination

We plan and coordinate all necessary utilities, including water, sewer, electrical, and gas where applicable. Utility planning is a critical factor that directly impacts both functionality and cost.

Clear planning in this stage ensures the detached ADU operates efficiently as a fully independent living space.

Detached ADUs for Specific Use Cases

We tailor detached ADU construction based on how you plan to use the unit. This includes rental-focused ADUs, in-law suites, guest houses, retirement-friendly units, and backyard offices.

Designing with a specific use case in mind ensures the finished space is practical, comfortable, and aligned with your intended purpose.

Step-by-Step Detached ADU Construction Process

A clear, step-by-step process is essential to avoid delays, unexpected costs, and confusion during a detached ADU project. Each phase is designed to give Sacramento County homeowners clarity, control, and confidence as the project moves forward.

1. Initial Consultation

We begin by understanding your goals, property conditions, and how you plan to use the detached ADU. Whether your focus is rental income, family housing, or flexible space, this step helps define the direction of the project.

2. Site Review and Feasibility

We assess your property to identify placement options, access points, utility pathways, and any constraints that may affect the build. This step answers one of the most important questions early: what is realistically possible on your lot.

3. Design and Scope Development

We translate your goals into a functional plan that fits your space and intended use. This includes layout planning, size considerations, and ensuring the design aligns with both usability and build feasibility.

4. Engineering and Permit Preparation

We prepare detailed construction documents and technical plans required for approvals. Proper preparation at this stage reduces the risk of delays and ensures the project is ready for the next phase.

5. Permit Coordination

We manage the submission process and help move your project through approvals. This includes addressing feedback and keeping the process organized so you are not left navigating it alone.

6. Construction and Project Management

We oversee the entire build process, coordinating each phase from foundation to final finishes. Structured management helps maintain consistency in quality, timeline, and execution.

7. Final Walkthrough and Completion

Once construction is complete, we walk through the finished unit with you to ensure everything is ready for use. The result is a fully functional detached ADU that aligns with your original goals.
