Cobb County Ordinances: Property, Noise, Parking, and Fines

The Cobb County ordinances govern day-to-day life in the unincorporated parts of the county, setting rules on how tall your grass can grow, where you can park a work truck, when you can burn yard debris, how loud is too loud, and what you need before running a business from home. Most violations carry fines up to $1,000, and the full code is free to read online through Municode, the county’s official digital repository.¹² The county’s authority to adopt these rules comes from the home rule provision of the Georgia Constitution, which allows county governments to regulate local property and affairs as long as the rules do not conflict with state law.³

One scope note before anything else: these rules apply in unincorporated Cobb County. If you live inside Marietta, Smyrna, Kennesaw, Acworth, Austell, Powder Springs, or Mableton, your city has its own code, and county code enforcement does not handle complaints there.

Property Upkeep, Grass, and Litter

The county treats weeds and grass taller than 12 inches as a nuisance. Owners are also responsible for keeping their lots clear of litter, debris, and trash that could draw pests or feed a fire. Dumping litter on any public or private property is illegal unless the site is designated for disposal or the material goes into a proper receptacle. For larger loads — more than ten pounds or 15 cubic feet — the fine is $1,000 per occurrence, and the county can bill the violator for cleanup costs.⁴

Yard trimmings have their own rule that trips people up: they cannot be mixed with regular household trash. If your hauler picks them up, they must be sorted and kept separate. Everything else residential has to go out in tied plastic or plastic-lined bags.⁴

Vehicles Parked at Home

Inoperable and junk vehicles generate some of the most common citations in Cobb neighborhoods. Any vehicle, trailer, or manufactured home without a valid license plate and current decal cannot sit on residentially zoned property unless it is stored inside a completely enclosed building. A tarp or carport does not count. So a car in the driveway with flat tires or a missing engine qualifies as a violation if the registration has also lapsed.⁵

Commercial vehicles have separate limits. A household may keep only one business vehicle used exclusively by the resident, and no business vehicle rated above 12,500 pounds gross weight can be parked on residential property at all. You also cannot park on grass or on unimproved surfaces between the road and your home’s front setback line.⁵ Landscaping and hauling operations run out of the house are a frequent source of complaints under this rule.

Noise

The noise provisions sit in Chapter 50, Article VII, starting at Section 50-256. The general test is whether the sound is plainly audible at a significant distance from the property line of its source. Construction, amplified music, and motorized landscaping equipment are the usual triggers. Quiet hours during the late night and early morning tighten the restrictions on loud mechanical and amplified activities. Outdoor speakers can draw complaints during the day too if the volume carries onto neighboring lots. The working rule of thumb: if your neighbor can clearly hear it from their yard, you are probably over the line.

Animals and Pets

Chapter 10 is the county’s animal code.⁶ Off your own property, your pet must be under direct physical restraint — not a voice command, not a shock collar, but a leash or carrier. The county enforces this as a strict rule.

An animal that causes property damage or physical injury, or one that poses a credible threat based on a prior attack, can be classified as dangerous, which brings heightened requirements for the owner. Persistent barking that disturbs neighbors can become a nuisance complaint and, eventually, a citation. All dogs and cats over four months old must be vaccinated against rabies by a licensed veterinarian, and you have to be able to produce proof if an animal control officer asks.

Outdoor Burning

The burning rules in Chapter 54, Article VIII are stricter than many homeowners expect. The following are flatly prohibited regardless of weather or season:

Petroleum-based materials such as tires, plastics, and roof shingles, and anything else that produces black smoke.
Household garbage of any kind.
Burning anything in a barrel, except in an approved incinerator or combustion unit.
Burning on county, city, or private roads.
Burning yard waste on any property other than the lot where it was cut or fell.

Even otherwise legal burns are off-limits on windy days (sustained winds of ten miles per hour or higher) or when cloud cover or rain would trap smoke near the ground. The fire chief can impose a blanket burn ban whenever local conditions make outdoor fires hazardous, and a ban covers residential fire pits too.⁷

Fines for burning violations escalate on a set schedule. A first violation gets a written warning. A second brings a $100 fine. The third jumps to $250, the fourth to $500, and a fifth or later violation can reach $1,000 and up to six months in jail.⁷

Fences and Sheds

Fence heights depend on where the fence sits on your lot. A fence or wall in the front yard adjacent to a public road right-of-way cannot exceed six feet. Rear-yard fences can go up to eight feet, with that cap counting posts and any decorative ornaments on top. All fences must be kept structurally sound, no fence may stand within a public right-of-way, and corner lots can face extra visibility rules near intersections.

Sheds have two sets of rules you have to pass separately. Georgia’s base building code exempts one-story storage sheds from building permit requirements when the floor area is 120 square feet or less. Cobb County’s zoning code then requires that any accessory building up to 144 total gross square feet sit at least five feet from the property line and stay under 15 feet in height. Skipping the building permit does not excuse the zoning setbacks, lot coverage, or height limits. If you add electrical, plumbing, or gas to a shed, those trade permits are always required.

Running a Business From Home

Anyone engaged in business in unincorporated Cobb County, full-time or part-time, must obtain an Occupation Tax Certificate before starting operations. The definition is broad: any trade, occupation, profession, or commercial enterprise carried on for gain, directly or indirectly. Independent contractors working on 1099s need their own certificate.⁸

Home-based businesses, called customary home occupations in the zoning code, are exempt from the Certificate of Occupancy that commercial locations have to get, but they still need the Occupation Tax Certificate. The zoning code limits what the activity can look like from the street: no storage of materials, equipment, or business vehicles on the property beyond the single business vehicle allowed per household, and sales of goods from the home are generally not allowed in residential zones.⁸⁵

One deadline that catches owners off guard: business personal property owned on January 1 — equipment, furniture, inventory — must be reported on Form PT-50P by April 1 each year. A 10 percent penalty applies to assets that go unreported or are reported late.⁸

Zoning and Signs

Land use questions, such as whether you can build an addition, convert a garage, add a second unit, or operate a particular kind of business, are governed by the zoning resolution in Chapter 134. Each residential district has its own minimum lot size, setbacks, floor area, and density rules, so checking your zoning classification is the first step before any project. Almost all signs also require a permit before installation, with only limited exceptions for certain temporary directional signs. Temporary on-premises signs like banners get a semiannual permit covering two 60-day display periods separated by at least 30 days.

How to Report a Violation

If you want to report an abandoned vehicle, an overgrown lot, illegal dumping, or any other suspected violation, the complaint goes to the county’s Community Development department. The online portal lets you search by address and submit an inquiry without creating an account. You can also email comdev@cobbcounty.gov or go in person to 1150 Powder Springs Street, Suite 400, in Marietta, Monday through Friday, 8:00 a.m. to 5:00 p.m.⁹

A code enforcement officer investigates after a complaint comes in. If the officer confirms a violation, the owner usually gets a warning notice or citation explaining what to fix and by when. Minor issues often close out without penalties when owners act quickly. Serious or repeated violations escalate to fines, administrative hearings, or court.

Fines, Court, and What Enforcement Actually Looks Like

Ordinance cases are heard in Cobb County Magistrate Court.¹⁰ Georgia law caps the penalty any county can impose for an ordinance violation at $1,000 in fines, six months in jail, or both. Jail sentences come with built-in leniency: the judge must probate at least 120 days of any sentence, so you would not serve the full term unless you violated the conditions of probation, and if a probated sentence is revoked, the maximum time actually served in a county jail is 60 days.¹¹

Some chapters write their own escalating fine schedules below those state caps, like the burning rules above. The penalty imposed cannot exceed whatever cap the specific ordinance itself sets, even where state law would allow more. Timelines vary: a simple complaint the owner fixes right away may never reach a courtroom, while a contested citation or repeat violation can take 30 to 45 days or more to get a hearing. If you receive a notice or citation, the document itself will specify your deadline to correct the problem and, if applicable, your court date.
