An unfinished basement is the most affordable way to add living space to a Henry County home. You already have the foundation, the walls and the roof. Here’s what McDonough-area homeowners should know about costs, timelines, permits and moisture before finishing a basement.
Basement finishing cost in Henry County
| Project scope | Typical range | What it usually includes |
|---|---|---|
| Basic finish | $15,000 – $28,000 | Framing, insulation, drywall, flooring, lighting and HVAC extension. No bathroom. |
| Full living space | $28,000 – $45,000 | Adds a full bathroom, a bedroom or office, and egress windows. |
| Premium suite or in-law apartment | $45,000 – $65,000+ | Wet bar or kitchenette, multiple rooms, higher-end finishes. |
Step 1: Deal with moisture first
Georgia’s clay soil and humidity make moisture the number one basement issue. Before any framing goes up, we check for water stains, efflorescence (white residue on concrete), musty smells and grading that slopes toward the house. Fixing a moisture problem first costs far less than tearing out finished drywall later. Waterproof flooring like LVP is a smart choice for basements.
Step 2: Plan the layout
Popular basement layouts in Henry County include:
- Family or media room with recessed lighting and a TV wall
- Home office away from household noise
- Home gym with rubber or LVP flooring
- Guest or in-law suite with a bedroom and full bathroom
- Wet bar or game room for entertaining
Adding a bathroom adds the most value and the most cost, especially if the basement wasn’t plumbed for one.
Step 3: Permits and code
Finishing a basement generally requires a building permit in Henry County, Clayton County and Spalding County, along with inspections for framing, electrical and plumbing. A bedroom needs a code-compliant egress window. We pull the permits and schedule inspections as part of every basement project. Permitted work also protects your resale value, because buyers and appraisers ask.
Step 4: Timeline
A basic finish usually takes 4–6 weeks. A full suite with a bathroom and kitchenette can take 8–12 weeks, partly because of inspection scheduling.
Ways to keep costs in check
- Leave some areas unfinished for storage and mechanicals.
- Put a bathroom where the plumbing rough-in already exists.
- Choose LVP over carpet or tile for durability and cost.
- Ask about our 20% senior and military discount and $0-down financing.
