In Chattanooga, playing a radio, phonograph or musical instrument, or yelling and shouting on the street, is prohibited between 11:00 p.m. and 7:00 a.m. when it disturbs the quiet of nearby residents. Amplified sound at a home cannot exceed 50 dB(A) between 9 p.m. and 9 a.m.
Chattanooga prohibits operating lawn mowers, leaf blowers, weed-eaters, chain saws or other domestic tools outdoors between 9:00 p.m. and 7:00 a.m. Daytime use is allowed. There is no separate decibel limit for these tools.
Chattanooga sets dB(A) sound-level caps by vehicle type and speed zone: in 35 mph-or-less zones, motorcycles are limited to 82 dB(A) and cars under 10,000 lbs to 80 dB(A). Car stereos audible 50+ feet away are also prohibited.
Chattanooga bars construction, demolition, alteration, repair and street excavation in any residential district except between 7:00 a.m. and 8:00 p.m. Work outside those hours needs a building-inspector permit granted only for urgent public-health or safety necessity.
Keeping a dog that disturbs residents with frequent or long, continued noise is unlawful in Chattanooga. The code defines this as barking averaging 10 or more barks per minute over 5 minutes, audible from 100 feet or more away.
Chattanooga caps amplified sound equipment at 55 dB(A) between 9 a.m. and 9 p.m. and 50 dB(A) between 9 p.m. and 9 a.m., measured at the nearest residential property line, unless a permit from the chief building official is obtained.
Neither Hamilton County nor Chattanooga sets aircraft noise limits. Aircraft operations and noise are regulated by the FAA under federal law, which preempts local rules. Noise abatement at Chattanooga Metropolitan Airport (Lovell Field) is handled by the airport authority under FAA programs.
Chattanooga measures noise on the A-weighting scale with a standard sound-level meter. Core residential amplified caps are 55 dB(A) by day and 50 dB(A) at night; vehicle limits run 80–90 dB(A); permitted events may not exceed 70 dB(A) at a home.
Outdoor amplified music that is plainly audible 100+ feet away on someone else's residential-zone property is prohibited in Chattanooga. The Downtown Amplified Music District allows up to 80 dB(A) midday under an AMD permit, dropping to 65 dB(A) late night.
Chattanooga has no separate industrial-zone decibel table; industrial noise is governed by the general prohibition on unreasonably loud noise plus specific bans on unmuffled exhausts, steam whistles, loud loading, and mechanical refuse loaders operating 9 p.m.–7 a.m. near homes.
Inside Chattanooga, every short-term vacation rental (STVR) needs a city STVR certificate before it advertises or hosts guests. Certificates split into owner-occupied 'homestay' and non-owner-occupied 'absentee' types. Unincorporated Hamilton County adopted its own STVR permit through Development Services in April 2023.
A Chattanooga STVR certificate is valid for one year and must be renewed annually. The current certificate must be posted inside the rental in a conspicuous spot. Renewal opens 30 days before expiration and a certificate expired more than 30 days cannot be renewed.
Chattanooga does not impose an annual cap on the number of nights an STVR may be rented. Instead, the definition limits each booking to 30 days or fewer; a stay of more than 30 continuous days is no longer a short-term rental. Homestays and absentee rentals can operate year-round if
Chattanooga charges $250 to apply for and renew a homestay STVR certificate and $500 for an absentee STVR. On top of that, guests pay lodging tax: Hamilton County levies a 4% hotel/motel occupancy tax and Chattanooga adds 4%, plus Tennessee's 7% state sales tax and local sales tax.
Chattanooga's homestay STVR must be the operator's primary residence, defined as living there at least 183 days a year. Absentee STVRs are for properties that are not the owner's primary residence and are restricted to commercial zones that permit hotels, not ordinary residential neighborhoods.
Chattanooga does not require the host to be physically on-site during every stay, but it draws the key line between homestay rentals (the owner's own primary residence) and absentee rentals (no resident owner). Absentee rentals without an on-site host are confined to commercial hotel-zoned properties.
A Chattanooga STVR is capped at five bedrooms, and any STVR in the R-1 or R-2 residential zones may contain no more than five (5) bedrooms. Occupancy is tied to bedroom count, and the use cannot function as a hotel, rooming house, bed-and-breakfast, or boarding house.
Chattanooga's published STVR certificate materials focus on zoning, fees, and posting rather than a stated liability-insurance minimum, and no specific coverage amount is confirmed in the accessible code. Hosts should carry short-term-rental or homeowner liability coverage and confirm any insurance documentation the Land Development Office requires.
Chattanooga's STVR review checks that a rental has adequate off-street parking for its guests under the property's zoning, but the city code does not publish a single fixed 'spaces-per-bedroom' figure for STVRs. Parking is evaluated with the certificate application by the Land Development Office.
Chattanooga does not set a separate STVR noise rule; short-term rental guests must comply with the city's general noise ordinance, which restricts loud, disturbing sound. Repeated noise or nuisance complaints can jeopardize an STVR certificate at renewal or lead to revocation.
Open burning of yard brush is banned county-wide from May 1 through Sept. 30. During the October–April season you need a permit from the Chattanooga-Hamilton County Air Pollution Control Bureau. County permits are $15; city permits $75.
Hamilton County does not impose a mandatory defensible-space or vegetation-clearance law like fire-prone Western states. Clearing brush is handled through the APCB burn-permit program and voluntary Firewise practices, not a required clearance zone.
Consumer fireworks are legal to buy and use in Tennessee, but discharge is restricted locally. In Chattanooga, fireworks must not be set off after 11:30 p.m. (extended to 12:30 a.m. on July 4th and New Year's Eve). Unincorporated county is more permissive.
Tennessee law requires an approved smoke alarm in every one- or two-family rental unit, audible in the sleeping rooms. Landlords must ensure alarms work before a new tenant moves in. Violations are a Class A misdemeanor under TCA 68-102-151.
Backyard fire pits, chimineas, and small recreational fires are allowed in Hamilton County without a burn permit, even during the May 1–Sept. 30 seasonal ban. Tennessee's fire code requires them at least 25 feet from any structure and constantly attended.
Small backyard cooking, warming, and campfires are permitted in Hamilton County without a burn permit, including during the seasonal ban. They must stay at least 25 feet from structures, be constantly attended, and be fully extinguished afterward.
Hamilton County has no separate propane-storage ordinance; storage follows Tennessee's adopted fire code and NFPA 58. On multi-family balconies, only small LP-gas containers of 2½ pounds or less water capacity are allowed near combustible construction.
Hamilton County is not divided into statutory wildfire-severity zones like Western states. Wildfire risk is managed by the Tennessee Division of Forestry, which requires a permit for any open burning within 500 feet of forest, woodland, or grassland from Oct. 15–Apr. 30.
Hamilton County has no smoker-specific ordinance. Wood and pellet smokers fall under the same Tennessee fire code as grills: fine at single-family homes, but banned on combustible multi-family balconies and within 10 feet of combustible construction.
Single-family homes can grill freely, but Tennessee's fire code bars charcoal and open-flame cooking devices on combustible balconies or within 10 feet of combustible construction at apartments and condos—unless the building is sprinklered or the LP container is 2½ pounds or less.
In Chattanooga, City Code § 24-286(e) bars parking or storing a recreational vehicle, camper, trailer or boat in a residential right-of-way between 9:00 a.m. and 7:00 p.m. Keep it on your own lot as accessory storage under zoning. The unincorporated county sets no street time limit; HOAs may be stricter.
On Chattanooga streets you must park parallel, facing traffic, with the right-hand wheels within eighteen inches of the curb (City Code § 24-289). Some neighborhoods are permit-only zones. In unincorporated Hamilton County, Tennessee's rules of the road (TCA Title 55-8) apply and there is no general county time limit.
Chattanooga bars parking a truck, trailer or vehicle with three or more axles, or over 14,900 lbs GVWR, in a residential district — on the street or on private property — except while loading (City Code § 24-286(f)). Properly zoned commercial or industrial property is exempt.
Neither Hamilton County nor Chattanooga has a dedicated residential EV-charging ordinance. A home Level 2 charger is installed under electrical and building permits using Tennessee's adopted electrical code (NEC). Commercial and multifamily charging must meet the applicable zoning off-street parking standards.
Neither Hamilton County nor Tennessee bans simple overnight street parking. Chattanooga has no citywide overnight ban, but a vehicle left illegally on public property over 48 hours (or unattended over 10 days) is "abandoned" under City Code § 24-341 and can be tagged and towed.
Chattanooga treats any discarded or abandoned vehicle on private land within the city as a public nuisance (City Code § 24-344) and bars leaving junked vehicles on streets (§ 24-343). Owners get at least 10 days' notice to remove; violations carry a fine up to $50 per day (§ 24-349).
In Chattanooga, marked freight curb loading zones may be used only for loading, and no longer than 30 minutes (City Code § 24-295); passenger loading zones allow only 3 minutes (§ 24-294). Off-street loading for new commercial development is set by zoning (Chapter 38 / RPA).
Hamilton County has no ordinance requiring a paved driveway. But Chattanooga City Code § 24-286(a)(2) prohibits stopping, standing or parking in front of any public or private driveway. Driveway design and new curb cuts follow zoning and need an access permit from the road authority.
Oversized vehicles — trucks, trailers or vehicles with three or more axles or over 14,900 lbs GVWR — may not park in a Chattanooga residential district, on the street or private property, except while loading (City Code § 24-286(f)). Junked oversized vehicles are a nuisance under § 24-344.
Residents may not paint public curbs. In Chattanooga, curb colors and no-parking signs are set by the city — parking against a yellow curb or a posted sign is prohibited (City Code § 24-286, § 24-287). Markings and striping are installed by the road authority; request a zone rather than
Chattanooga's zoning ordinance sends fence height to the Building Code. Under that code a building permit is generally required only when a fence exceeds 7 feet in height; shorter residential fences typically need no building permit but must still meet placement and sight-visibility rules.
Chattanooga zoning allows fences and walls to be built directly on the lot line, so a boundary fence between neighbors is permitted. The fence must still stay on your own property and out of easements and rights-of-way.
In Chattanooga, fence height is set by the Building Code, not the zoning ordinance. A building permit is generally required only for fences over 7 feet tall. Unincorporated Hamilton County follows its own Zoning Regulations via the Regional Planning Agency.
Chattanooga's zoning ordinance does not list prohibited fence materials for typical residential fences, but any fence at a street intersection must comply with the City Code's sight-visibility rules. The Building Code governs structural aspects of fence construction.
Chattanooga's zoning ordinance keeps fence requirements simple: fences and walls may be built on the lot line, and their height is governed by the Building Code. Fences must also stay clear of easements and meet corner sight-visibility rules.
Chattanooga zoning regulates retaining walls through the Building Code rather than the zoning ordinance. A structural retaining wall typically needs a building permit and engineering, especially above modest heights, and cannot sit inside a utility easement without approval.
Standard fence materials (wood, vinyl, chain-link, masonry) are allowed in Chattanooga; the zoning ordinance sets no general material list. The main constraint is corner sight-visibility, and structural walls follow the Building Code.
In Chattanooga's RN-1-7.5 single-family zone, homes need a 25-foot front setback, 5-foot interior side setbacks, and a 25-foot rear setback. Setbacks vary by zone; unincorporated Hamilton County uses its own Zoning Regulations.
Chattanooga limits maximum building coverage to 60% of the lot in its standard residential zones (50% for non-residential uses in those zones). A detached accessory building also cannot cover more ground than the main house.
Chattanooga caps building height at 35 feet across its RN-1 through RN-2 residential zones. Detached accessory structures are limited to 24 feet and can never exceed the height of the main house. Unincorporated county height limits come from the county Zoning Regulations.
Tennessee bans private possession of inherently dangerous (Class I) wildlife such as big cats, bears, and large primates; these may be kept only by zoos, circuses, and permitted propagators. Hamilton County and Chattanooga may add further local restrictions.
Beekeeping is legal in Hamilton County and is encouraged as agriculture under Tennessee's Apiary Act. The county sets no specific hive rule; on unincorporated land hives are broadly allowed, while Chattanooga zoning may set placement limits on residential lots.
Cats in Hamilton County are not required to be leashed, but every cat six months or older must be vaccinated against rabies under Tennessee law. Roaming cats causing a nuisance or found unvaccinated can be impounded by McKamey Animal Center.
Keeping chickens and livestock is generally allowed on agriculturally zoned unincorporated Hamilton County land, protected by Tennessee's right-to-farm law. Inside Chattanooga and other cities, zoning limits or bans fowl and farm animals on small residential lots.
In Chattanooga and Hamilton County, dogs must be leashed or confined whenever off the owner's property; letting a dog run at large is unlawful and enforced by McKamey Animal Center. State law also makes owners civilly liable for a loose dog's harm.
Neither Hamilton County nor Chattanooga bans specific dog breeds like pit bulls. Tennessee regulates dangerous dogs by behavior, not breed: any dog that attacks and seriously injures a person can be ordered destroyed under state law.
Hamilton County has no blanket ban on feeding wildlife, but a 2026 Tennessee law makes it a misdemeanor to feed black bears in posted no-feeding zones. Feeding that attracts nuisance animals or creates a health hazard can still be abated locally.
Tennessee law makes it unlawful for livestock owners to willfully let animals run at large, so Hamilton County livestock must be fenced or confined. Where livestock may be kept is set by county zoning for unincorporated land and by city codes inside towns.
Hamilton County sets no countywide numeric cap on household pets. Chattanooga and other cities regulate large numbers through kennel-permit and nuisance provisions rather than a flat limit, so many dogs or cats can trigger permit or nuisance rules.
Animal hoarding in Hamilton County is addressed through Tennessee's animal-cruelty laws and local nuisance and kennel rules. McKamey Animal Center investigates neglect, and keeping animals in unsanitary or overcrowded conditions can lead to seizure and criminal charges.
Chattanooga's Tree Ordinance does not prohibit homeowners from removing trees on their own private property, including backyards. Permits apply to public/right-of-way trees and to new development, which must meet tree-caliper requirements or pay into the city Tree Bank.
No Hamilton County or Chattanooga ordinance specifically bans or requires a permit for residential artificial turf. In required landscape areas of development, zoning standards may not credit synthetic turf as living landscaping. Check HOA rules, which the county and city do not enforce.
Pruning trees on your own private property in Chattanooga generally needs no permit. But street/public trees in the right-of-way are protected by the Chattanooga Tree Ordinance and may only be trimmed or removed with the city arborist's approval.
Chattanooga treats weeds like tall grass: grass, underbrush, or weeds must be kept under 10 inches. Overgrown lots are tagged as public nuisances by Code Enforcement. Unincorporated Hamilton County uses nuisance provisions instead of one countywide weed height.
Tennessee has no statewide homeowner lawn-watering ban, and neither Hamilton County nor Chattanooga imposes fixed watering days. During drought, Tennessee American Water requests voluntary conservation. Mandatory restrictions would only come if a severe, prolonged drought forced them.
In Chattanooga, grass, underbrush, or weeds must be kept under 10 inches tall. Code Enforcement tags overgrown lots. Tennessee counties zone unincorporated land, but this height rule is a Chattanooga city standard, not a countywide Hamilton County one.
Chattanooga encourages backyard composting and offers free mulch and compost to city residents. No ordinance bans a tidy home compost pile. The city collects brush, bagged yard waste, and loose leaves curbside; piles must not block streets, sidewalks, or drainage.
Rainwater harvesting is legal in Tennessee with no state permit or volume limit for non-potable uses like irrigation. Chattanooga actively encourages it, even reimbursing residents for rain barrels and stormwater features. Collected water cannot be used for drinking without treatment.
Neither Hamilton County nor Chattanooga requires homeowners to plant native species, and there is no ban on turf lawns. Native and pollinator plantings are encouraged. Zoning landscape standards mainly govern required buffers, parking-lot planting, and new development, not private yard plant choice.
A residential pool in Hamilton County needs a building/construction permit from the county (or city) Building Inspections Department, built to the adopted 2018 IRC. Public/community pools also require state plan approval from the Tennessee Department of Health before construction.
Above-ground pools holding water over 36 inches deep are treated as swimming pools under Tennessee law, so they need a barrier, and if installed after January 1, 2011, a pool alarm. A permit is generally required to install one.
Pools must be enclosed by a barrier. Tennessee's adopted residential code requires a 48-inch barrier around private pools, and the Tennessee Department of Health requires public pools be enclosed by a fence at least four feet high with self-closing, self-latching gates.
Tennessee law counts hot tubs and nonportable spas holding water over 36 inches deep as swimming pools, so barrier and pool-alarm requirements can apply. Spas with an approved lockable safety cover are commonly exempt from separate fencing under the adopted code.
Tennessee's Katie Beth's Law requires a pool alarm on any pool installed after January 1, 2011. Public pools must also post depth markers and "NO DIVING" signs where diving is unsafe under Department of Health rules.
Hamilton County allows home occupations as an accessory use without a separate license if they meet the zoning standards: only residents may work there, no more than 25% of the dwelling's floor area is used, no on-site sales, and no outside evidence of the business.
Under the Tennessee Food Freedom Act, homemade foods like baked goods, candies, jams, and dried mixes can be sold directly to consumers without a license, permit, or state inspection. There is no sales cap. Proper labeling is required and some perishable items remain restricted.
Home occupations are a permitted accessory use in Hamilton County's residential zones, allowed in the operator's own dwelling as long as no advertising sign, merchandise, products, or equipment is displayed for advertising. Inside cities, the municipal zoning code governs instead.
A home occupation in unincorporated Hamilton County may display no advertising sign except one nameplate no larger than two square feet. On parcels mapped "Live & Work" in the East Brainerd Corridor plan, one non-illuminated nameplate up to nine square feet is allowed.
A day care center in unincorporated Hamilton County needs a special permit approved by the county, with a site plan, county-approved access, a secured playground, and the neighborhood's residential character maintained. Small home childcare is also licensed by the Tennessee Department of Human Services.
Vacant lots in Chattanooga must be mowed and kept free of litter. City code bars depositing litter on any vacant or occupied property regardless of ownership, and the 10-inch overgrowth limit applies to all premises, including empty lots.
Chattanooga has adopted the International Property Maintenance Code and enforces blight through its Code Enforcement office. Deteriorated structures, accumulated junk, and inoperable vehicles on private land are prohibited. Unincorporated Hamilton County relies on county nuisance rules and city standards.
Neither Hamilton County nor Chattanooga imposes a dedicated yard-sale permit for occasional residential sales; they are allowed as an accessory home use. Temporary sale signs must follow the city sign code and cannot be placed in the public right-of-way.
Chattanooga property-maintenance rules require premises to be kept free of accumulated garbage, rubbish, and refuse. Trash must be stored in containers, not piled or scattered. Code Enforcement handles complaints inside the city; unincorporated county follows nuisance rules.
In Chattanooga, grass, underbrush, and weeds on any premises must be kept below 10 inches. Owners and tenants are responsible for the whole lot, including the strip to the street. Overgrowth is a common code-enforcement violation.
Chattanooga requires garbage carts within 2 feet of the curb, at least 3 feet from any obstruction, and 5 feet from parked vehicles. Wheels and handle face the curb and lid arrows point to the street, out by 7:00 a.m.
The City of Chattanooga collects residential garbage weekly. Carts must be at the curb by 7:00 a.m. on your collection day, and all waste should be in tightly secured bags. Unincorporated Hamilton County residents use county convenience and recycling centers.
Chattanooga bars depositing litter on any vacant or occupied property, and Tennessee's litter law (TCA 39-14-502) makes littering a crime countywide. Penalties scale from a Class C misdemeanor for small amounts up to a Class E felony for large or commercial dumping.
Chattanooga collects bulk items (furniture, mattresses, appliances) and brush on a monthly, four-area rotating schedule. Each service is limited to 12 collections per property in any 12 months. Pile items at the curb, in separate piles, by 7:00 a.m. Monday of your week.
Chattanooga offers biweekly curbside recycling. Accepted materials include cardboard, paper, plastic bottles with necks (no clamshells), and clean steel and aluminum cans. Recyclables must be clean, loose (not bagged), with the cart lid fully closed by 7:00 a.m.
Chattanooga zoning lets an existing detached garage be legally converted into an accessory dwelling unit. Once approved as an ADU, it may add cooking facilities and must meet the 800-square-foot ADU standards; otherwise garages cannot contain kitchens above parking.
A detached carport in Chattanooga may not sit closer than five feet to any lot line, is banned from required front and corner side setbacks, and cannot exceed 24 feet wide, 22 feet long, and 15 feet high.
In Chattanooga, a detached shed or accessory structure must sit at least five feet from interior side and rear lot lines, stay out of front and corner side yards, top out at 24 feet, and never exceed the height or footprint of the main house.
In Chattanooga (Hamilton County's seat), one accessory dwelling unit is allowed per single-unit detached lot, capped at 800 square feet, on a permanent foundation and same owner. Detached ADUs go in the rear or interior side yard only.
Chattanooga has no separate tiny-home ordinance; a backyard tiny house is regulated as an accessory dwelling unit. It must sit on a permanent foundation, stay under 800 square feet, and cannot be a shipping container or recreational vehicle.
Chattanooga treats political signs as exempt yard signs needing no permit. They may be up to 32 square feet and 10 feet tall, but all political yard signs must be removed within 15 days after the election they refer to.
Garage-sale signs in Chattanooga are permit-exempt yard signs. They may be up to 32 square feet, displayed no more than 15 days before and 30 days after the sale, and cannot be attached to trees, poles, or placed in the right-of-way.
Chattanooga zoning limits lighting to one footcandle at any lot line and requires all outdoor luminaires to be shielded so no glare falls on adjacent lots or the public right-of-way, protecting neighbors from spillover light.
Chattanooga's zoning code requires all outdoor luminaires to be full cutoff design, caps permitted lighting color temperature at 3200K, and bans searchlights, laser lights, and neon or LED outlining of buildings, cutting glare and skyglow.
