Garage Construction in Metro Atlanta
Whether you need a detached two-car garage, an attached addition, or want to convert an existing garage into living space, JMJ Construction Group builds garages across metro Atlanta and matches your home's roofline, siding, and trim so the new structure looks original, not improvised.
A garage is real construction: foundation, framing, roofing, electrical, and usually a permit and setback review. As a licensed Georgia general contractor, we own the full scope. Garage projects often overlap with our home addition work when a bonus room or suite is built above the garage.
Garages and conversions, matched to your home
Detached and attached garages
We build freestanding one, two, and three-car garages, as well as new attached garages that are structurally and visually integrated into your home. The right choice depends on your lot, setbacks, and how you'll use the space. A detached garage offers flexibility and workshop potential, while an attached garage adds everyday convenience.
- Detached one-, two-, and three-car garages
- New attached garages
- Workshops and detached storage
- Foundation, framing, roofing, and electrical are handled in-house
Garage conversions and bonus rooms
Converting an existing garage into a bedroom, office, gym, or in-law suite is one of the most cost-effective ways to add finished square footage, because the structure already exists. The work involves insulation, HVAC, proper egress, and finishes to meet living-space standards. We also build finished rooms and studios above the garage when you want to add space without giving up parking.
- Garage-to-living-space conversions
- Over-garage bonus rooms and studios
- Insulation, HVAC, and egress to code
- Single-to-double garage expansions
Matched to your home, built to code
A garage that clashes with the house hurts its value, so we match rooflines, siding, and trim on every build. And because new garages and conversions must meet setback and code requirements that vary across the metro, we confirm those and handle permitting and inspections before construction begins.
What goes into a garage project
Garage pricing depends on a few clear factors. Knowing them makes your estimate easy to read.
- Size: a single-car garage costs far less than a three-car or garage-with-bonus-room
- Detached vs. attached: each has different foundation, roof, and connection costs
- Finishes: insulation, drywall, and electrical for a workshop or living space, add scope
- Conversions: turning a garage into a living space adds HVAC, insulation, and egress
- Setbacks and permits: requirements vary by jurisdiction, and we handle them

Garage questions, answered
How much does it cost to build a garage in Atlanta?
It depends on the size, whether it's attached or detached, and how much of the interior you finish. A basic detached single-car garage and a large finished garage with a bonus room sit far apart. We provide a free, itemized estimate for your specific build.
How much does a garage conversion cost?
Converting a garage into living space usually costs less than building an addition from scratch because the structure already exists, but it does require insulation, HVAC, proper egress, and finishes. We'll price your specific conversion in a free, detailed estimate. Larger conversions overlap with our home additions work.
Do I need a permit to build a garage in Georgia?
Yes. New garages and conversions require permits and must meet setback and code requirements that vary by jurisdiction across the metro. As a licensed Georgia general contractor (GCI000260), we handle permitting and inspections for you.
Can you match my new garage to my existing home?
Absolutely, that's a priority on every garage we build. We match the roofline, siding, and trim so the garage looks like part of the original home and protects your property's value.
Are you licensed and insured?
Yes. JMJ Construction Group holds a Georgia GC license GCI000260 and carries liability coverage through Next Insurance, with proof available before work begins.
Do you offer free estimates?
Yes. We assess your property, talk through your goals, and provide a detailed written estimate at no cost and no obligation.
