City of Atlanta · 2026 guide

Atlanta tree protection, in plain language.

Know which trees are regulated, how projects affect roots, where to apply, and when an arborist report or tree protection plan may help.

Pruning, removal, damage, or other work affecting a public tree requires City authorization.

Measure the main stem diameter four and one-half feet above natural grade.

01 / First question

Is the property actually inside the City?

An Atlanta mailing address does not prove City of Atlanta jurisdiction. The city crosses Fulton and DeKalb counties, while many “Atlanta” postal addresses sit in other municipalities or unincorporated areas.

Best first step

Search the official City GIS property viewer by address or parcel. If the property is not shown within City limits, identify the incorporated city or unincorporated county before using this guide.

02 / Permit paths

The reason for removal changes the process.

Healthy trees

Removal is not automatic.

A regulated healthy tree requires a permit. The City reviews whether a permitted improvement reasonably requires removal, whether the design minimizes impacts, and whether preservation, planting, density, and recompense requirements are met. Landscape-only and forest-improvement paths also have specific criteria.

Dead, dying, or hazardous

Apply for a DDH determination.

The owner or authorized agent applies with property and tree information plus photos. Seven or more trees require an assessment by a registered tree professional. The City Arborist makes the final DDH determination. Approved DDH removals usually avoid replacement and recompense, subject to listed exceptions.

Imminent failure

Emergency removal is narrowly defined.

First request immediate approval from the City Arborist. If the Arborist cannot be reached and the tree presents an imminent likelihood of failure, the ordinance allows removal followed by a retroactive application and evidence within five business days. A failure to prove the condition can trigger replacement, recompense, and fines.

Invasive or undesirable

A permit is still required at the threshold.

Private-property invasive or undesirable trees at six inches DBH or greater require a permit. Posting is not required. Replacement or recompense generally does not apply, except that removing seven or more undesirable trees outside a building, demolition, or land-disturbance permit can trigger tree-for-tree replacement or a tree-density demonstration.

Public trees

Do not treat the right-of-way as private.

Any tree on a right-of-way, in a park, or on other public property is regulated regardless of size. Pruning, removal, or other work requires authorization through the public-property process. Public tree removal carries separate replacement rules.

03 / Construction impact

Tree protection is a site-design issue, not just a fence detail.

Construction, demolition, grading, trenching, paving, utilities, equipment, and material storage can affect regulated trees even when no trunk is removed.

Critical root zone1 foot radius per 1 inch DBH

The default CRZ for a free-standing tree without apparent root restrictions. The City Arborist may adjust it for documented site conditions.

Atlanta Code § 158-26Current municipal code
Saved tree80% CRZ protected

A saved tree generally keeps at least 80 percent of its CRZ at natural grade and the full structural root plate protected.

Atlanta Code § 158-52(b), 158-63Current municipal code
Prescription range20%–33% impact

The City Arborist may approve this impact range only with an approved arboricultural prescription and mitigation.

Atlanta Code § 158-64Current municipal code
Structural root plateFully protected

No cut, fill, or land disturbance is normally allowed in the SRP because it anchors the tree.

Atlanta Code § 158-52(b), 158-63Current municipal code

04 / Plans + prescriptions

What a project team may need to submit.

Construction, demolition, land-disturbance, and landscape-related tree-removal applications require a scaled site plan reviewed by the City Arborist. The ordinance calls for a tree survey of regulated trees, including DBH, species, location, CRZ, SRP, boundary-tree status, removal or save status, and protection measures. A licensed land surveyor must provide tree locations and existing-condition surveys where required.

Arboricultural prescription

Where the City allows certain CRZ impacts, a registered certified arborist may need to prescribe and oversee mitigation such as root pruning, canopy pruning, mulching, watering, soil care, and enhanced protection, with reporting and a five-year survivability assessment.

05 / Replacement + recompense

Approval to remove can still carry an offset.

Healthy trees approved for removal are generally replaced inch-for-inch: one caliper inch of replacement for each inch of removed DBH. Replacement plantings receive a 1.25-times caliper credit. On-site tree density must still be met, and monetary recompense cannot replace that minimum.

For 2026, remaining unplanted replacement caliper inches are multiplied by $140. Beginning in 2027 the rate adjusts annually for inflation. Conditional caps, credits, planting feasibility, zoning, project type, and public-tree rules can materially change a calculation, so use the City-approved plan and current rate.

06 / Professional registration

Submitting professionals must be registered with the City.

Tree service companies working in Atlanta, and arborists, foresters, landscape architects, or other professionals who prepare or sign tree protection plans, permit documents, condition assessments, species identification, or arboricultural prescriptions must meet the registration requirements in section 158-33. Arborists submitting or signing permit documents must hold current ISA or ASCA certification.

Source review

Current through August 25, 2026.

Reviewed against the City ordinance resource page, the current codified Chapter 158 text including the February 2026 amendments, City Arborist materials, City forms, ATL311 guidance, and the Accela permitting portal.

The City adopted the revised ordinance in June 2025 for a January 1, 2026 effective date. The current code includes corrections and clarifications adopted in February 2026, including the 26-O-1015 amendments. Project requirements can depend on submission timing, later amendments, administrative standards, and the City Arborist's findings.
