Nashville's Tree Protection: The Rules That Matter

Every city handles tree protection a little differently. In Nashville, Tennessee, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Protected Tree Species

Metro Code Chapter 17.24 protects landmark and specimen trees on public property and on private development sites. Removal of designated trees requires Urban Forester approval, and replacement is calculated by trunk diameter using density unit credits.

Key details: Code section: Metro 17.24. Standard unit: Tree density units (TDU). Penalty multiplier: Up to 3x replacement. Enforcer: Metro Urban Forester.

Unpermitted removal of a specimen or landmark tree on a regulated site can require replacement at three times the TDU value, plus restoration costs. Civil penalties under Metro Code can exceed 500 dollars per tree per violation.

This is not one of those rules that cities tend to ignore. Nashville actively enforces its protected tree species requirements.

Parkway Planting

NDOT and the Metro Urban Forester regulate planting in the public right-of-way, including parkways between sidewalk and curb. Residents must obtain a permit and plant approved species at proper spacing and clearances from utilities and signs.

Key details: Permit issuer: NDOT + Urban Forester. Free-tree partner: Root Nashville. Code basis: Metro Title 13 ROW. Owner duty: Establishment watering.

Unauthorized parkway planting can trigger removal at the property owner's expense and a citation under Metro right-of-way encroachment rules. Improper species near power lines may be re-pruned aggressively or removed by NES.

Urban Forest Equity

Root Nashville, a public-private partnership coordinated by the Cumberland River Compact and Metro, targets 500,000 new trees by 2050 with priority planting in low-canopy, high-heat neighborhoods identified through the Livable Nashville equity analysis.

Key details: Goal: 500,000 trees by 2050. Coordinator: Cumberland River Compact. Priority: Low-canopy neighborhoods. Funding: Public + private + 17.24 fees.

Root Nashville is a voluntary planting program with no penalties. Property owners who accept a free tree but neglect establishment watering may simply lose the tree without further sanction.

Nashville is more permissive than most cities when it comes to urban forest equity. That said, there are still limits.

Tree Removal Permits

Nashville requires tree removal permits for protected trees under the Metro Tree and Landscape Code (Title 17, Chapter 17.40, Article X). Trees with a diameter at breast height (DBH) of 12 inches or more on development sites are considered protected. The Urban Forestry Division reviews permit applications and may require replacement plantings.

Key details: Code Section: Metro Code Ch. 17.40, Article X. Protected Size: 12 inches DBH or larger. Review Agency: Urban Forestry Division. Replacement: Required at specified ratios or pay into Tree Fund. Penalty: Up to $1,000 per tree plus replacement.

Removing protected trees without a permit can result in fines of up to $1,000 per tree, required replacement plantings at enhanced ratios, and stop-work orders on development sites.

Compared to other cities, Nashville takes a harder line on tree removal permits. The enforcement and penalty structure reflects that.

Heritage & Protected Trees

Nashville provides enhanced protection for heritage and specimen trees through the tree protection ordinance (Chapter 17.40, Article X). Heritage trees — generally those of exceptional size, species, or historical significance — receive the highest level of protection and require Metro Council approval for removal in certain circumstances.

Key details: Code Section: Metro Code Ch. 17.40, Article X. Protection Level: Highest — enhanced protections. Removal Standard: Must show no reasonable alternative. Replacement: Enhanced ratios — 3:1 or higher. Administration: Urban Forestry Division.

Unauthorized removal of heritage trees carries the highest penalties under the tree ordinance, including maximum fines, enhanced replacement ratios (potentially 3:1 or higher), and potential legal action for damages.

This is one of the stricter rules in Nashville's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Tree Replacement Requirements

Nashville requires tree replacement when protected trees are removed during development. The Metro Tree and Landscape Code (Chapter 17.40, Article X) specifies replacement ratios based on the size and species of removed trees. Developers may plant replacement trees on-site or pay into the Metro Tree Fund.

Key details: Code Section: Metro Code Ch. 17.40, Article X. Standard Ratio: Caliper-inch-for-caliper-inch. Alternative: Payment into Metro Tree Fund. Warranty Period: Minimum 2 years. Approved Species: Nashville Urban Tree Planting Guide.

Failure to plant required replacement trees or maintain them during the warranty period can result in fines and required additional plantings. Development final inspections may be withheld until replacement requirements are met.

This is not one of those rules that cities tend to ignore. Nashville actively enforces its tree replacement requirements requirements.

Tree Ordinances

Nashville's tree protection regulations under Metro Code Chapter 17.24 and Title 17.40 Article X require tree surveys, preservation plans, and replacement for protected trees during development, enforced by the Metro Urban Forester.

Key details: Code: Title 17.40 Art. X; Ch. 17.24. Protected Size: 24-inch DBH or greater. Permit Required: Commercial and multi-family projects. Heritage Program: Historic and Specimen Trees registry. Enforced By: Metro Urban Forester.

Unauthorized removal of protected trees may result in fines and mandatory replacement at a ratio determined by the Urban Forester, including caliper-inch replacement requirements.

The Bottom Line

Nashville is tougher than many cities when it comes to tree protection. Out of the 7 rules covered here, 4 are rated strict. If you are a homeowner, renter, or business owner in Nashville, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
