ADU Building Services by Carolina's Building Company in Charlotte, NC
Carolina's Building Company is a Charlotte-based ADU contractor that handles the full process of adding an accessory dwelling unit to a residential property. Their services cover feasibility assessment, design, permitting, and construction — offering homeowners a single point of contact from the initial idea through to move-in day.
Homeowners across Charlotte are choosing to build ADUs for practical reasons. Some want a dedicated space for aging parents or adult children. Others are looking for a private home office or creative studio. Many are interested in generating rental income without purchasing a second property. Carolina's Building Company works with each of these scenarios, helping clients find a layout and approach that fits both their property and their budget.
Types of ADUs Carolina's Building Company Builds
Not every lot or household has the same needs, and Carolina's Building Company offers several accessory dwelling unit types to reflect that. The main options they work with include:
- Detached backyard cottage — A fully separate structure, suited to larger yards where strong privacy between units is a priority. This is a common choice for full-time living or long-term rental use.
- Over-garage suite — Built above an existing garage, this option keeps the yard open while adding a usable living or rental space.
- Attached side or rear unit — Connected to the main home, this works well on smaller lots or where shared access between occupants is acceptable.
- Interior conversion — Turning existing basement space or underutilized interior areas into a livable unit. Often the most cost-effective starting point.
- Garage conversion contractor work — Converting an existing garage into a living space, home office, or studio when the garage is no longer used for parking.
They also design ADUs intended primarily as workspaces or creative studios. These still meet local safety and building code requirements but are configured around work and hobbies rather than full-time residential use.
During an on-site meeting, the team reviews three key factors with the homeowner: how the space will be used day to day, the shape and slope of the yard, and the realistic budget range. From there, they develop a design-build plan that balances function, appearance, and cost in a transparent way.
Costs, Timelines, and Charlotte's ADU Regulations
Carolina's Building Company breaks down project costs into clear categories rather than presenting a single lump-sum figure. These categories typically include:
- Site preparation and foundation
- Structure and shell
- Interior finishes and fixtures
- Utility connections and any required upgrades
In general terms, interior conversions tend to be the most affordable since some structure already exists. Attached units and garage conversion projects sit in the middle range, while detached backyard cottage builds are typically at the higher end of the cost spectrum.
Most projects take between three and six months from start to finish. Variables such as grading, crew access, weather, permitting timelines, and HOA requirements can all affect the final schedule. The team provides a realistic range upfront and communicates progress at each stage.
Charlotte's updated zoning rules — the Unified Development Ordinance — have expanded opportunities for accessory dwelling unit construction, but clear boundaries still apply. Carolina's Building Company helps homeowners understand the specific rules for their address, including maximum unit size relative to the main home, placement requirements, height limits, and parking expectations. They also flag common issues early, such as utility easements, tree protection zones, and how existing structures on the lot can limit placement options.
Their process follows a structured six-step system:
- Feasibility and property review
- Concept planning and early budgeting
- Full design-build planning
- Permitting handled start to finish
- Construction with ongoing transparency
- Final inspection and move-in
