How Chattanooga Handles Landscaping Rules: A Practical Guide

Chattanooga maintains 131 local ordinances across all categories, and 4 of those deal specifically with landscaping rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Chattanooga falls on the strict-to-permissive spectrum compared to other cities.

Tree Trimming

Chattanooga requires property owners to prune trees overhanging streets and sidewalks to a minimum clearance -- eight feet over sidewalks, twelve feet over most streets, fourteen feet over truck routes.

Key details: Governing law: Chattanooga City Code § 32-311(a)-(b). Sidewalk clearance: 8 feet minimum. Street clearance: 12 feet minimum. Truck thoroughfare clearance: 14 feet minimum.

Failure to maintain required clearance or remove hazardous limbs is enforced by the City Forester as a nuisance under Sec. 32-319--32-321, with a written abatement notice, a City-performed fix billed to the owner, and a possible civil penalty.

Weed Ordinances

A separate, older Chattanooga nuisance provision also caps weeds at 10 inches: growth over that height, or that breeds mosquitoes or smells foul, is a declared nuisance.

Key details: Height threshold: Over 10 inches = nuisance. Also covers: Mosquito-harboring, odor-emitting growth. Abatement window: 15 days after posted notice. Appeal: Hearing before city council in 5 days.

Failing to cut weeds over 10 inches within 15 days of the County health director's posted notice lets the City abate the nuisance and place a lien on the property for the costs (§§ 20-23, 20-27).

Tree Removal & Heritage Trees

Chattanooga can order a private property owner to remove dead or diseased trees that endanger life, property, or nearby trees, giving the owner fourteen days to comply before the City removes it and bills them.

Key details: Governing law: Chattanooga City Code § 32-315. Who decides: City Forester. Compliance window: 14 days from written order. Cost if City removes: billed as special assessment.

Missing the fourteen-day removal window lets the City remove the tree and bill the owner directly, collected the same way as other special assessments against the property.

Native Plants

Chattanooga generally requires grass and weeds kept under 10 inches, but Sec. 21-136(d) exempts City approved RainSmart Yards and projects approved through the RainSmart Rewards program that adhere to the program's maintenance requirements, giving certified native-plant and rain-garden landscaping a path around the standard overgrowth ordinance.

Key details: General height limit: 10 inches, grass/weeds/underbrush. Exemption program: RainSmart Yards / RainSmart Rewards. Exemption condition: Must meet program maintenance requirements. Enforcement: City abates and bills owner, Sec. 21-137. Emergency exception: No citation during declared disaster.

Growing regular grass, weeds or underbrush over 10 inches without RainSmart Yards or RainSmart Rewards approval is prosecutable under Sec. 21-136(b), and the City can enter the property to cut the growth and bill the owner for the cost plus administrative fees. Sec. 21-137 requires the Code Official to give written notice and a chance to remedy the violation, with abatement costs becoming a lien on the property if the owner does not comply within ten days.

The rules around native plants in Chattanooga lean permissive, but that does not mean anything goes.

The Bottom Line

Chattanooga's landscaping rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Chattanooga is broadly strict or permissive.
