Why adus & in-law suites works the way it does in Greer
About Greer, SC. Greer straddles the Greenville–Spartanburg county line and sits next to GSP International Airport and the BMW manufacturing campus. That proximity makes it the default landing spot for transferring engineers, executives, and supplier-company hires moving into the Upstate, and the housing stock reflects that — a mix of newer master-planned subdivisions, golf-course communities, and older small-town blocks around downtown Greer.
What it means for adus & in-law suites. Greer's flatter, gently rolling terrain on the eastern side of Greenville County tends to produce cleaner residential lots than the city core, but build sites near the airport face FAA height considerations and noise overlays. Greenville and Spartanburg County code paths both apply depending on address, which surprises some out-of-state buyers. Common work here is new custom homes in gated communities, large additions to 90s-era homes that are aging into a remodel cycle, and corporate-relocation builds where the family is closing on a relocation timeline driven by an employer start date.

What We Do
One Property, Three Generations, Zero Compromise
Mother needs her independence; you need yours. Detached ADUs ($100K–$300K+) with their own kitchen, bath, and HVAC. Attached mother-in-law suites under $100K sharing utilities with the main home. Internal conversions for the in-between. Greenville County zoning, septic, and HOA review — we walk the lot before you fall in love with a plan that won't permit.
- Three classifications — detached, attached, or internal — chosen against your lot reality
- Designed to look like they were always there: matched trim, rooflines, finishes
- Greenville County code-compliant — adds resale value, not backyard sheds with electrical
- Permits, septic capacity, and zoning review handled before the first wall goes up

What Affects the Price
Every job is different. Here's what we look at when we put together your estimate — so there are no surprises on job day.
ADU type: detached structure, attached suite, or internal conversion
Square footage and number of bedrooms / baths
Septic system capacity and any utility extension required
Whether the ADU shares any 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
We don't quote over the phone. Every estimate is done on-site because that's the only way to give you a number you can count on. No ballparks, no surprises.
Our Process
How We Approach
ADUs & In-Law Suites
Lot, Septic & Zoning Review
Greenville County zoning rules around detached ADUs are not the same as the city's, and septic capacity is the most common silent disqualifier. We walk the lot, pull current ordinances, and tell you up front what's possible — before you fall in love with a plan that won't permit.

Design It To Look Like It Was Always There
Trim profiles, rooflines, and material selections matched to your existing home. The goal is resale-positive, not 'backyard shed with electrical.' Three ADU classifications — detached, attached, or internal — chosen against your privacy, septic, and cost realities.

Permit, Build & Hand Over Two Front Doors
Full mechanical, plumbing, code-compliant egress. Detached ADUs get their own kitchen, bath, and HVAC. Mother needs her independence; you need yours. The result is a structure that adds resale value and gives every generation under your roof their own space.

Common Questions
ADUs & In-Law Suites FAQ
Answer
Three classifications. Detached ADUs share no walls with the main home — fully self-sustaining with their own kitchen, bath, and mechanical. Attached units share an external wall with the main home (often called mother-in-law suites). Internal ADUs convert existing home space into a self-contained living area.
