BHR Construction: ADU and In-Law Suite Builder in Greenville County
BHR Construction specializes in accessory dwelling units (ADUs) and in-law suites across the Upstate South Carolina region. Whether the goal is multi-generational living, housing a returning college student, or generating rental income, they work with homeowners to build code-compliant living spaces on existing residential properties.
They handle three classifications of ADUs: detached ADUs, attached mother-in-law suites, and internal conversions. Each comes with its own cost profile, zoning path, and construction requirements — and BHR Construction works through those differences with homeowners before any plans are finalized.
- Detached ADUs — standalone structures with their own kitchen, bathroom, and HVAC system
- Attached suites — connected to the main home and sharing some utilities
- Internal conversions — self-contained spaces within the existing footprint, often paired with a broader addition or remodel
All work is designed to meet Greenville County zoning and code requirements. BHR Construction reviews septic capacity, HOA restrictions, and current ordinances before a project moves forward — reducing the risk of investing in a plan that won't receive permits.
What Goes Into the Estimate
Pricing for ADU and in-law suite projects is scope-driven. BHR Construction does not quote over the phone. Every estimate is conducted on-site, based on the specific conditions of the lot and the homeowner's goals. Factors that influence the final number include:
- ADU type — detached structure, attached suite, or internal conversion
- Square footage and number of bedrooms and bathrooms
- Septic system capacity and any utility extension required
- Whether the ADU shares walls or systems with the main home
- Finish tier — standard, designer, or luxury (Shaw, Pelican, Armstrong)
- Site access, grading, and any tree removal on the proposed footprint
A free feasibility consultation is offered, during which BHR Construction walks the lot and delivers a firm budget tier. This approach is intended to avoid surprises later in the process.
Design, Permits, and Build Process
BHR Construction approaches ADU projects in a structured sequence. The first step is a lot, septic, and zoning review. Greenville County rules around detached ADUs differ from city regulations, and septic capacity is frequently the factor that limits what's buildable. They pull current ordinances and assess the lot before any design work begins.
On the design side, the goal is for the finished ADU to look like it was part of the original property — with trim profiles, rooflines, and materials matched to the existing home. The intent is to add resale value rather than simply add square footage.
The build phase covers full mechanical, plumbing, and code-compliant egress. Detached ADUs receive their own kitchen, bath, and HVAC. The typical delivery window is 6 to 12 months, depending on scope and permitting timelines.
