Cobb County Short-Term Rental Rules Explained

“Cobb County” is a single name covering several different sets of rules. For a short-term rental operator, that distinction is the whole game: a property in Marietta, a property in Smyrna, a property in Kennesaw, a property in Acworth, and a property in unincorporated Cobb County are each governed by a different authority — and applying the wrong one can mean an unnecessary permit, a missed obligation, or operating out of compliance without realizing it.

This post is a general orientation to how short-term rentals are regulated in Cobb County. It is not legal advice, and it is not a substitute for verifying current requirements directly with the relevant government office.

Cobb County Is Several Jurisdictions, Not One

Cobb County government has authority over unincorporated Cobb — land that isn’t inside any incorporated city. But Cobb also contains a number of cities with their own governments and their own ordinances, including:

• The City of Marietta (the county seat)
• The City of Smyrna
• The City of Kennesaw
• The City of Acworth

A property inside one of these cities follows that city’s rules. A property in unincorporated Cobb follows the county’s. These are separate systems with separate enforcement, and a registration or approval in one place does not carry over to another.

If you aren’t certain which jurisdiction your property falls under, don’t guess from a ZIP code or mailing address — those don’t reliably indicate municipal boundaries. Check your property tax records, look up the parcel in Cobb County’s GIS or property portal, and call both the county and any nearby city to confirm.

How Short-Term Rentals Are Generally Regulated Here

Across Georgia, cities and counties increasingly regulate short-term rentals through some combination of zoning, registration or permitting, and occupancy / hotel-motel tax, layered on top of private HOA covenants. Cobb County and its cities fit that pattern, but the specific mix differs by jurisdiction.

Unincorporated Cobb no longer leans on zoning alone. The Board of Commissioners adopted a short-term rental ordinance — Chapter 78, Division 11 — on 27 September 2022, and it took effect on 1 January 2023. It defines a short-term rental as lodging provided for compensation “for a period of time not to exceed 30 consecutive days,” and it requires a short-term rental certificate from the business license division before a property is rented at all. No more than one certificate is issued per dwelling unit; short-term rentals are permitted in all Residential (R) districts; the application must include a sworn statement that any applicable homeowners or property owners association has been notified; and penalties run $500 for a first violation in twelve months, $750 for a second, and revocation plus a twelve-month bar on reapplying for a third, with each night of unlicensed operation counted as a separate violation.

That ordinance applies only to unincorporated Cobb. Its Applicability section binds “any owner of any property within the unincorporated areas of Cobb County,” which means it does not reach Marietta, Smyrna, Kennesaw or Acworth. This is the single most common mistake in guides written about this county, and it cuts both ways: an owner inside a city may believe they need a county certificate they cannot obtain, and an owner just outside one may believe they are unregulated when they are not.

The cities set their own position, and it is not uniform. Marietta, notably, had adopted no dedicated short-term rental ordinance as of its council’s May 2026 discussion of the subject — the Marietta Daily Journal reported that operators there are not required to hold a business licence and that council members were debating whether to create a registry. Rules around occupancy, parking and quiet hours differ city to city, and the position in any one of them can change.

Because these frameworks have been revisited as the market has grown, treat any specific rule you read online — including this one — as a starting point, not a final answer.

What to Verify Before You List in Cobb

A sensible due-diligence sequence for any Cobb County property:

Step 1 — Confirm your exact jurisdiction. Unincorporated Cobb, Marietta, Smyrna, Kennesaw, or Acworth. Use parcel records and direct confirmation.

Step 2 — Contact the right authority for permitting/registration. Once you know the jurisdiction, ask that specific office (Cobb County, or the city’s planning / zoning / business-license department) what is currently required.

Step 3 — Check zoning. Confirm short-term rental use is allowed for your parcel’s zoning designation before you spend on furnishing or photography.

Step 4 — Read your HOA or condo documents. Many Cobb subdivisions and condo associations restrict short-term rentals outright. This is parallel to — and independent of — any government rule.

Step 5 — Understand your tax obligations. Identify which state and local lodging taxes apply, who collects them, and what you must file yourself. A licensed CPA who works with Georgia short-term rental operators is worth the call.

Step 6 — Verify anything legal with a professional. For interpretation of an ordinance or a tax-filing question, an attorney or CPA is the right source — not a blog post or a platform help article.

A Note on Cobb’s Demand Side

The reason owners work through Cobb’s compliance steps is that the underlying market is strong. Cobb is a corporate-heavy county anchored by major employers, Truist Park and The Battery, Kennesaw State University, and the Cobb Galleria — demand drivers we cover on our Cobb County market page. Getting compliance right simply protects that opportunity.

Rules Change — Confirm Before You List

Short-term rental regulation in Cobb County and its cities continues to evolve. Rules change frequently — confirm current requirements with Cobb County, or with the City of Marietta, Smyrna, Kennesaw, or Acworth as applicable, before listing your property or renewing any registration. A figure or rule that was accurate last year may not be accurate today.
