ADU Construction Services by D.A.R.T Construction in South Carolina
D.A.R.T Construction builds accessory dwelling units across South Carolina, handling projects from the initial feasibility check through to final inspection. Their scope covers a range of ADU types, including detached backyard cottages, garage apartments, over-garage suites, in-law suites, and backyard studios.
The team manages the full range of technical and regulatory requirements that come with ADU construction — utility coordination, setback and lot-coverage compliance, fire separation standards, and inspections. Throughout the build, they work to keep the property orderly and safe, and where possible, they phase the work so homeowners can remain in the primary residence during construction.
As an ADU contractor operating in tight urban and suburban sites, D.A.R.T Construction places emphasis on disciplined planning. They map access routes, protect existing landscaping, and stage materials to reduce disruption. Milestones are tracked, decisions are documented in writing, and issues are addressed before they affect the schedule. Their approach to accessory dwelling unit construction focuses on clean workmanship within compact footprints — precise framing, weather-tight shells, and finishes built for everyday use.
The ADU Build Process
D.A.R.T Construction follows a structured, phased process for every ADU build:
- Feasibility & Site Readiness — Local requirements are reviewed, setbacks and lot coverage are noted, utility locations are confirmed, and site access and staging are mapped before work begins.
- Scope, Estimate & Schedule — Scope and allowances are defined, a line-item estimate is provided, and a realistic timeline is set with inspection checkpoints and target dates.
- Preconstruction & Approvals — Permitting is coordinated, long-lead items are ordered, temporary services are arranged, and the site is prepared with fencing, erosion control, and safety signage.
- Structure & Systems — Foundations, framing, roofing, windows, and weatherproofing form the building envelope, while electrical, plumbing, and HVAC rough-ins are completed and inspected.
- Finish, Tie-Ins & Commissioning — Interior and exterior details are installed, utility tie-ins are completed, all systems are verified, and a thorough clean is carried out before the final walkthrough.

As a detached ADU builder and backyard cottage builder in South Carolina, they bring a practical approach to code compliance. Permits, documentation, and inspections are handled proactively so regulatory requirements don't stall the schedule.
