ADU Construction Process

Building an Accessory Dwelling Unit (ADU) requires careful planning, expert coordination, and a clear understanding of each phase. A well-executed process ensures the project runs smoothly and efficiently from start to finish. Homeowners need a builder who can navigate each stage while delivering consistent communication and quality results. With property constraints, local regulations, and tight timelines often in play, a structured approach becomes essential to success.

Every site presents its own set of challenges and possibilities. A strategic construction process helps reduce delays, avoid budget surprises, and maintain alignment between design intent and finished product. This approach leads to an ADU that performs well, looks cohesive, and serves its intended purpose for years to come.

Doug Pruett Construction Company, Inc. specializes in thoughtful residential construction that respects both time and budget. Our experienced team understands how to guide clients through each stage while staying focused on long-term value.

Our Adu Construction Process

We follow this structured, step-by-step process that allows each ADU to take shape with precision, purpose, and clarity:

First Consultation and Site Assessment - Every project begins with a walkthrough and conversation to understand your goals and evaluate the site. We assess access points, grading, utility connections, and how the ADU will align with the main structure.
Feasibility and Budget Planning - We analyze local codes, setbacks, and zoning rules to confirm buildability. At the same time, we establish a realistic budget that allows for materials, permits, and potential contingencies.
Design Collaboration - Our team collaborates with you to finalize a layout that reflects your intended use of the space. We ensure that the floor plan is efficient, the exterior design complements the property, and the structure meets all relevant municipal requirements.
Permit Preparation and Approval - We prepare all necessary documentation for submission to your local planning and building departments. This includes architectural drawings, energy calculations, and structural engineering details.
Pre-Construction Preparation - Before breaking ground, we coordinate all materials, schedule trades, and confirm timelines to ensure a seamless project execution. Our crew prepares the site, installs any required erosion control measures, and secures the necessary inspections that must be completed before foundation work begins.
Foundation and Framing - Construction begins with the foundation system suited to your site. Once complete, we proceed to frame the structure, install the roof, and enclose the building.
Mechanical and Utility Installation - We install electrical, plumbing, HVAC, and any special systems according to plan. Each stage involves inspections to ensure all work complies with local codes.
Interior and Exterior Finishes - Once systems are in place, we complete insulation, drywall, flooring, cabinetry, trim, and exterior siding or finishes. We maintain consistent quality control throughout this phase to keep the project on track.

Our Cost-Effective ADU Construction Approach

Efficient construction starts with clarity and we begin each project with a clear understanding of scope, budget, and timeline, ensuring that no time is lost to miscommunication or rework. Our team ensures accuracy at every step, minimizing the need for costly changes during the build. This saves both time and resources, which ultimately keeps the overall cost under control.

We also take material selection seriously, helping clients make informed choices that balance aesthetics, function, and durability without unnecessarily exceeding their budget. Our approach yields a streamlined construction experience and a finished unit that embodies careful planning and responsible execution.
