How Much Does It Cost To Finish A 1500 Square Foot Basement In Stone Mountain?

Homeowners in Stone Mountain often ask what it takes to turn a 1,500 square foot basement into livable space. The short answer: expect a range of $75,000 to $165,000 for a full finish in 2025, depending on design, materials, and mechanical work. Most projects with Heide Contracting: basement finishing services in Atlanta, GA. a mid-range scope land between $95,000 and $135,000. Homes in Stone Mountain and nearby East Lake, Decatur, and Tucker share common conditions: block foundations, mixed moisture history, and ceiling heights around eight to nine feet. Those details push budget and schedule more than many people expect.

This guide explains the real cost drivers, what choices matter, and how a contractor to finish basement projects in the Atlanta area prices the work. It also shows where to spend for value and where to hold the line without risking problems later.

The baseline: what a true “finished basement” includes

A complete finish goes beyond paint and flooring. It brings the space up to the standard of the main level. For a 1,500 square foot basement in Stone Mountain, a baseline scope usually includes framed walls, insulation, drywall, doors and trim, LVP or carpet, lighting, switches and outlets, paint, and a code-compliant bedroom with egress if planned. It also includes HVAC supply and return adjustments, dehumidification strategy, and some plumbing stub-ins if a bathroom or wet bar is part of the plan.

At this level, with plain finishes and an open layout, budgets often start around $50 to $65 per square foot. In real numbers, that places a 1,500 square foot finish near $75,000 to $97,500 before upgrades.

What pushes the cost up in Stone Mountain

Soils and water management matter here. Red clay holds moisture. Many homes near Stone Mountain Park have mild seepage or past hydrostatic pressure issues. Correcting that adds cost but protects the investment. Ceiling height is the second big driver; ductwork reroutes and beam cladding add labor. Then come the features: bathrooms, bedrooms, media rooms, and built-ins.

• Water and humidity control: Interior French drains with a sump typically run $4,000 to $10,000 for a 1,500 square foot footprint. A basic dehumidifier with a dedicated drain adds $900 to $1,800 installed. If wall efflorescence is present, budget for masonry prep and vapor barriers.
• Bathroom build-out: A full basement bath with a shower usually ranges $12,000 to $25,000. If the home needs a sewage ejector pump because the main line sits higher, add $3,500 to $6,000.
• HVAC modifications: Extending existing ductwork and balancing usually falls between $2,500 and $6,000. A separate mini-split for a media room adds $4,500 to $8,000.
• Egress and bedrooms: Converting space into a legal bedroom with emergency escape can require a code-sized window well. Cutting foundation and installing a unit ranges $4,500 to $9,500.
• Sound and media: Basic soundproofing (insulation and resilient channels) for a theater adds $2 to $5 per square foot of that room. A modest 7.2.4 prewire and equipment rough-in typically runs $2,000 to $4,500.

With one bathroom, an enclosed bedroom with egress, media prewire, mid-grade finishes, and moisture control, the 1,500 square foot project often reaches $110,000 to $145,000.

Finish levels and real examples

Entry level, clean and bright: Open plan, storage room left unfinished, LVP flooring, LED cans, painted drywall, minimal built-ins. No bathroom. Moisture control via dehumidifier. Typical cost: $80,000 to $100,000. This fits homes off Rockbridge Road where owners want play space and a gym.

Family zone with bath and flex room: Adds a full bath, a guest room with egress, better lighting layers, and a small wet bar. Typical cost: $115,000 to $145,000. Common in neighborhoods near Hugh Howell Road where guests visit often.

Entertainment focus: Theater with sound treatments, custom bar with undercounter fridge and ice, accent walls, upgraded stairs, and concealed storage. Typical cost: $145,000 to $165,000+. Seen in Smoke Rise where ceilings run higher and mechanical relocations are worth the spend.

Permits, codes, and inspections in DeKalb County

Basement projects in Stone Mountain require building, electrical, mechanical, and plumbing permits. DeKalb County enforces energy code for basement insulation, smoke and CO detectors tied to the home system, and proper stair geometry. Expect two to three inspections during framing, rough-in, and final. Permit fees vary by scope; $700 to $2,200 is a common range for a 1,500 square foot finish with a bathroom. A qualified contractor to finish basement spaces handles drawings, load calcs for any beam work, and coordinates inspections to keep the schedule tight.

Moisture first, finishes second

Finishes fail when moisture is ignored. Efflorescence lines, small puddles after heavy storms, or that musty smell are all signals. Before drywall goes up, correct grading outside, extend downspouts past planting beds, and test for vapor drive. On the inside, use a capillary break at the slab (underlayment for LVP or carpet pad designed for basements), rigid foam or closed-cell spray foam on exterior walls where allowed, and a continuous vapor retarder. Skipping this step to save $3,000 to $8,000 can cost far more in mold remediation.

Where to invest vs. where to save

Spend on the building envelope, mechanicals, and lighting. Save on finishes that can be upgraded later.

• Invest: Drainage, insulation, dehumidification, egress, quiet HVAC, and layered lighting with dimmers. These affect comfort, safety, and resale.
• Save: Prefab bar cabinets instead of custom, LVP instead of site-finished hardwood, standard tile sizes, painted stair stringers instead of full refinish.

Timeline expectations

Most 1,500 square foot basements in Stone Mountain run 8 to 12 weeks of active construction after permits. Moisture remediation or structural changes can add two to three weeks. Special-order items like egress windows and custom shower glass can add another week if not ordered early. A clear schedule with milestone payments tied to inspections protects both homeowner and contractor.

Common line items with typical ranges

• Framing and insulation: $8,000 to $18,000 based on wall count and foam choices
• Drywall, doors, trim, paint: $15,000 to $28,000 for clean finishes and standard profiles
• Electrical (lighting, outlets, low-voltage rough): $6,500 to $12,000
• Flooring (LVP or carpet): $6,000 to $14,000 depending on product and stairs
• Plumbing rough and fixtures for one bath: $12,000 to $25,000
• HVAC modifications or mini-split: $2,500 to $8,000
• Moisture management: $4,000 to $10,000
• Egress window/well: $4,500 to $9,500 Real bids depend on access, stair geometry, ceiling obstructions, and existing panel capacity. Many Stone Mountain homes need an electrical panel upgrade when adding a theater or full bar; that adds $2,000 to $4,000.

Design choices that play well in Atlanta basements

Ceiling strategy sets the tone. A flat drywall ceiling looks clean but limits access; a well-planned drop in the mechanical corridor can hide main trunks and provide future service points without making the entire space feel low. Warm LED temps around 3000K work well with LVP and painted block. For floors, choose rigid-core LVP with an integral pad rated for basements. In the bath, use porcelain tile and a properly sloped shower pan with a dedicated exhaust fan on a humidity sensor.

Acoustic comfort matters in two-story homes. Insulate the basement ceiling cavities with mineral wool over living areas. Add a solid-core door at the stair. These small steps protect the main level from movie night bass and treadmill noise.

Resale and appraisal notes

Appraisers in the Atlanta metro give credit for finished basements but at a lower rate per square foot than above-grade space. Quality and functionality still pay off. A legal bedroom with egress and a full bath shows well in listings and draws more tour traffic. Clean moisture records and permit documentation reduce buyer hesitation. For Stone Mountain owners planning to sell within five years, aim for a neutral palette and durable materials that photograph well.

Getting an accurate quote in Stone Mountain, Decatur, and Tucker

Photos help, but site visits matter. A thorough contractor will check for slab flatness, foundation cracks, ceiling height at the lowest beam, and main drain elevation. They will confirm panel capacity, map ductwork, and test for moisture with a meter, not guess by smell. Expect a written scope that lays out framing, electrical counts, fixture allowances, and a clear line for bathroom and egress work.

Two or three competitive proposals are healthy. Be wary of a number that is 20% lower than the rest; it often omits moisture control, permits, or code-required egress, which surfaces as change orders later.

A quick checklist before you start

• Verify water management plans inside and out
• Decide on a bathroom location based on drain height
• Confirm egress needs if adding a bedroom
• Choose ceiling strategy by zone, not one-size-fits-all
• Lock lighting counts and switch locations early
