Atlanta & Georgia Homeowners — Read This Before You Convert Your Garage Into an ADU…

Your Atlanta Garage Is Sitting There Doing Nothing for Your Property Value — Here's How Georgia Homeowners Turn It Into a Fully Livable ADU Without Breaking Ground on New Construction

Atlanta homeowners who've priced out a detached ADU from scratch usually land on the same realization — the garage sitting on their lot is already most of the structure they'd be paying to build. The slab's there. The framing's there. What's missing is permitting, utilities, and someone who knows how to turn a place for parking a car into a place someone can legally live.


Art Design & Construction coordinates every step of a garage-to-ADU conversion — design, permitting, and every licensed trade — under one written contract with one accountable project lead, so what starts as an empty garage ends as a code-compliant, livable space.

What every Georgia homeowner should confirm before hiring any garage-to-ADU conversion contractor:

→ A written estimate before demolition begins

→ Proof of licensing for all trade work

→ A single named project manager accountable for results

→ Confirmation your existing garage foundation and framing were actually inspected, not assumed

→ Permitting and code-compliance handled as part of the project scope, not billed as a surprise later

Art Design & Construction meets every one of these standards. Every project. Without exception.

Why So Many Atlanta Garage-to-ADU Conversions Stall Out Before They're Livable — and What Happens When Nobody Checks the Structure First

It starts with a number that sounds too good to be true.


A detached ADU built from scratch runs well into six figures — but a garage conversion?


That's supposed to be the cheap version. The foundation's already poured. The walls are already framed. How expensive can it really be to just... finish it?


Then someone actually opens the walls. The slab wasn't poured to residential living-space standards, and now it needs supplemental footing before anyone can legally put a bedroom on top of it. The garage's single electrical circuit was fine for a car and a lawnmower — it's nowhere close to code for a kitchen, a bathroom, and a mini-split system.


And the permitting office in Cobb County doesn't process a "garage conversion" the same way it processes a simple remodel, because legally, you're not remodeling a garage anymore.


You're building a dwelling. None of this means the garage conversion isn't worth doing — it almost always still costs less than ground-up new construction, and it still adds real, appraised value. It means the "cheap and easy" version of this project doesn't actually exist. The version that goes smoothly is the one where somebody assessed the actual structure before quoting a number, instead of assuming a garage is a garage is a garage.

"A garage conversion isn't a discount ADU — it's a full ADU build that happens to start with a head start on the foundation and framing. Treat it like a shortcut and you'll find out the hard way what the garage was never designed to do." — Art Design & Construction

We manage the full garage-to-ADU conversion process across Marietta, Woodstock, Roswell, and all of Georgia — structural assessment, design, permitting, and every licensed trade — under one written contract with one accountable project lead who inspects the actual structure before anyone commits to a number.

Frequently Asked Questions About Garage Conversion ADUs in Atlanta GA

Real answers to what Atlanta homeowners ask most before converting a garage into an ADU.

Q1: How much does it cost to convert a garage into an ADU in Atlanta?

Typical range runs $60,000–$150,000 (Angi Cost Guide), but the real number depends entirely on your existing garage's foundation, framing condition, and how much utility work is required. We inspect the actual structure before giving you a number — not a range that turns into a moving target.

Q2: Is a garage conversion actually cheaper than building a detached ADU from scratch?

Usually, yes — you're starting with an existing foundation and framing instead of building both from nothing. But it's not automatically cheap; older garage slabs and single-circuit electrical often need real structural and utility upgrades to meet residential living-space code.

Q3: Are you a licensed general contractor?

We operate as a construction manager, coordinating a network of licensed trade professionals on every project — giving you one accountable team instead of managing subcontractors yourself.

Q4: Do you handle permitting with Cobb County for a garage conversion?

Yes — and it matters more here than on a typical remodel, because a garage-to-ADU conversion is legally a change of use, not a cosmetic update. Permitting is mapped into your project timeline from the design phase.

Q5: Can any garage be converted into an ADU?

Most can, but not all garages are equally ready — foundation type, ceiling height, and existing utility access all affect scope and cost. We assess your specific structure before confirming feasibility.

Q6: What's the difference between a detached and attached garage conversion?

A detached garage conversion becomes a fully independent structure. An attached conversion requires additional work to separate it — structurally and often for utilities — into a legally independent dwelling unit.

Q7: Do garage conversion ADUs add real value to my property?

Garage conversion ADUs consistently rank among the higher-ROI ADU types, since you're not paying to build a foundation and shell from scratch — most of that cost is already sitting on your lot.

Q8: How is an ADU different from just finishing a garage as a bonus room?

An ADU is a fully independent dwelling unit — its own kitchen, bathroom, and separate entrance, built to residential living-space code. A bonus room doesn't require the same utility or code work, but it also can't be rented or lived in independently.

Q9: Who's the best garage conversion ADU contractor in Atlanta?

When that's for you to decide against your own walkthrough — you can ask any contractor you're considering three things: did they actually inspect your garage's structure before quoting, is my timeline mapped against permitting, and will I have one point of contact. If the answers aren't clear, keep asking.

Georgia-wide, we manage the whole thing: assessment, permitting, licensed trades, one accountable team. —
