Our Prefab ADU Installation Services

We provide full-scope prefab ADU installation services throughout Sacramento County, covering every stage from feasibility to final turnover.

Site Assessment and Feasibility

We conduct a detailed evaluation of your property to determine the most efficient and code-conscious approach for prefab ADU installation. This includes reviewing access routes for delivery trucks and cranes, identifying setback requirements, analyzing slope and grading conditions, and locating utility connection points. We also assess potential constraints such as overhead lines, tight lot configurations, and neighborhood access limitations commonly found across Sacramento County.

Permit Coordination and Planning

We support the planning phase by aligning your prefab ADU installation with Sacramento County regulations and local jurisdiction requirements. This includes coordinating documentation, reviewing plans for compliance, and preparing your project for smooth approval and execution. Our goal is to reduce delays by ensuring everything is aligned before construction begins.

Site Preparation

Our team prepares your property for installation through professional grading, excavation, trenching, and staging setup. We ensure proper drainage, stable soil conditions, and clear access for delivery and crane operations. This phase is critical for preventing installation issues and keeping your project on schedule.

Foundation Installation

We build precise slab or raised foundations designed specifically for prefab ADUs. Our process focuses on accurate measurements, proper leveling, reinforcement, and anchoring preparation. A well-executed foundation ensures safe placement, structural integrity, and long-term performance of your ADU.

Delivery and Crane Coordination

We manage all logistics related to prefab unit delivery and placement. This includes route planning, crane access evaluation, staging coordination, and safe lifting procedures. On installation day, we ensure the unit is properly aligned, positioned, and secured with minimal disruption to your property.

Utility Hookups

We handle the connection of essential systems, including water, sewer, gas, and electrical services. This may involve trenching, tie-ins, and electrical panel upgrades depending on your property’s infrastructure. Our approach ensures your ADU is fully functional, efficient, and ready for inspection.

Exterior Completion

After placement, we complete all exterior work required to protect your ADU from the elements. This includes roofing integration, siding installation, flashing, insulation, window and door fitting, and weatherproof sealing. Proper exterior completion ensures durability and long-term performance.

Interior Finish Work

We finalize the interior to make your ADU fully livable and ready for use. This includes drywall, painting, flooring, trim, kitchen installation, bathroom setup, and fixture connections. Our focus is on delivering a clean, functional, and move-in-ready space.

Final Inspection and Turnover

We prepare your prefab ADU for final inspection by reviewing all work, addressing any required corrections, and ensuring compliance with local codes. Once approved, your unit is ready for occupancy, rental use, or immediate integration into your property.

How Our Prefab ADU Installation Process Works

Every prefab ADU installation project follows a structured, step-by-step workflow designed to reduce delays, eliminate guesswork, and ensure your unit is installed correctly the first time. Our process is built around real-world installation challenges in Sacramento County, including access limitations, utility coordination, and inspection requirements.

Step 1: Property Review and Feasibility Analysis

We begin with a detailed on-site evaluation of your property. This includes analyzing access routes for delivery trucks and cranes, confirming zoning setbacks, reviewing slope and grading conditions, and identifying existing utility connection points. We also assess potential risks such as overhead power lines, narrow driveways, and tight lot configurations commonly found in areas like Midtown Sacramento, Land Park, and older neighborhoods.

At this stage, we answer critical questions early so you avoid costly surprises later in the project.

Step 2: Planning, Permits, and Project Coordination

Once feasibility is confirmed, we align your project with Sacramento County and city-specific requirements. We coordinate planning documentation, review compliance factors, and establish a clear installation timeline. This phase ensures all moving parts—from prefab manufacturer schedules to local approvals—are properly aligned before work begins.

This reduces delays, prevents rework, and keeps your project moving efficiently.

Step 3: Site Preparation and Foundation Construction

We prepare your site through grading, excavation, trenching, and drainage setup. Proper site preparation ensures stability and accessibility for installation day. We then construct a slab or raised foundation designed specifically for your prefab unit, ensuring accurate leveling and dimensional precision.

A properly built foundation is critical for safe placement, structural performance, and long-term durability.

Step 4: Prefab Delivery and Crane Placement

We coordinate all logistics related to delivery and placement of your prefab ADU. This includes planning transport routes, setting up staging areas, and scheduling crane operations. On installation day, we manage safe lifting, precise alignment, and secure placement of the unit onto the foundation.

This is one of the most critical phases of the project, where experience and coordination make a significant difference.

Step 5: Utility Connections and System Integration

After placement, we connect all essential systems, including water, sewer, electrical, and gas where applicable. This may involve trenching, tie-ins, and panel upgrades depending on your property’s infrastructure. We ensure all systems are properly integrated, functional, and ready for inspection.

This step transforms the structure into a usable living space.

Step 6: Exterior and Interior Completion

We complete all remaining work required to finalize your ADU. Exterior work includes roofing connections, siding, windows, doors, and weatherproofing to protect against the elements. Interior work includes drywall, painting, flooring, cabinetry, kitchen and bathroom installation, and fixture setup.

This phase focuses on turning the installed unit into a finished, livable environment.

Step 7: Final Inspection, Compliance, and Turnover

We prepare your ADU for final inspection by reviewing all completed work and addressing any required corrections. Once approved, your prefab ADU is ready for occupancy, whether for rental income, extended family use, or personal living space.

The result is a fully installed, move-in-ready ADU that is built to meet local requirements and your long-term goals.
