For homeowners in Marietta, the decision to hire a certified arborist is not just a matter of preference, but a crucial one. The impact of tree work on safety, permits, insurance coverage, and cost cannot be overstated. Choosing the right professional can mean the difference between a smooth, compliant job and a costly problem.


Across Marietta and nearby communities—East Cobb, Kennesaw, and Smyrna—local rules and permitting apply to pruning and tree removal. Certified arborists are knowledgeable about navigating these requirements, carry the proper insurance, and document their work. This guide explains when permits are required and what liability looks like in such cases.

What a certified arborist means

A certified arborist is a tree-care professional who has passed a rigorous examination and maintains continuing education in tree biology, pruning, risk assessment, and safe removal techniques. Their expertise, backed by recognized industry standards and proper insurance, ensures the safety of your home and your financial security.

How To Verify

  • Ask for the arborist’s certification number and expiration date. A current credential confirms recent training and active status; an expired one indicates that the certification has been terminated.

  • Make sure the name on the credential matches the legal business name on your written estimate. Mismatched names can indicate a borrowed license or an undisclosed subcontractor, which can complicate liability in the event of a claim.

  • Request Certificates of Insurance for general liability and workers’ compensation, issued directly by the insurer. Review effective dates and limits, and ask to be listed as the certificate holder so you receive the document from the carrier. This protects you if property is damaged or a worker is injured.

  • Confirm in writing who will handle Marietta permits and any HOA approvals. Unpermitted removals can result in fines, stop-work orders, or replanting requirements; a qualified company will manage the paperwork and include these fees in the proposal.

  • Get a detailed scope of work and job plan in writing. It should specify which trees/limbs are being pruned or removed, the methods and equipment to be used (climbing, aerial lift, rigging), lawn and property protection, utility locates, cleanup and debris haul-off, stump-grinding depth, and the start/finish timeline.

Why It Matters In Marietta

Marietta places its tree rules in the zoning code to protect healthy trees and ensure hazardous or dead trees are handled safely. For many removals, the city requires a Notification of Tree Removal before work commences. That submittal typically includes photos, a simple site sketch, and—when safety or health is the reason—an arborist’s note. Missing or incorrect paperwork can delay your project or trigger fines.

Common triggers for city notice/approval (not a complete list):


  • Trees over a specific trunk diameter or trees on commercial or multifamily sites.

  • Removals tied to building, grading, driveway, or utility work.

  • Trees in buffers, setbacks, or near the public right-of-way.

  • Trees are claimed to be dead, dying, or dangerous.

What a certified arborist does for you:


  • Confirms whether notice or a permit is required and prepares the documentation.

  • Provides a signed hazard/health assessment with supporting photos.

  • Coordinates with the city and any HOA, and schedules inspections if needed.

  • Keeps records to ensure your project remains compliant and you avoid stop-work orders.


Working with a certified arborist in Marietta means your tree work follows local rules, protects your liability, and moves forward without costly surprises.

Who Pays If Someone Gets Hurt

Tree work is hazardous. If a worker is uninsured and gets injured on your property, the claim can fall on you. Protect yourself by requiring written proof of general liability and workers’ compensation before any work begins. Request Certificates of Insurance issued by the carrier, verify the effective dates and limits, and ensure the insured business name matches the one in your estimate. If subcontractors will be used, confirm they’re covered under those policies.

Obtain a detailed scope of work in writing and confirm that the contractor will adhere to Marietta rules and handle any required city paperwork. “Cheap” hired help can look good up front, but uncovered damages, fines, or injury claims are far more expensive later.

Utility Lines And The 811 Rule

Before stump grinding, planting, or any removal where roots may be disturbed, request a utility locate (811). This free service marks underground gas, electric, water, and communications lines so crews can work safely and avoid costly outages or injuries. Schedule the locate ahead of your job date and keep the flags/paint in place until the work is completed.


If trees are near overhead lines, only qualified line-clearance professionals should work in that area. A certified arborist will coordinate with the utility and plan safe methods to ensure your project remains compliant and incident-free.

Step-by-Step Tree Service Process in Marietta

1. Assessment by a Certified Arborist

A certified arborist conducts a comprehensive inspection of the tree’s structure, defects, and overall health. This thorough assessment provides you with a clear plan, complete with photos and recommendations, before any work begins, instilling confidence in the proposed course of action.


2. Paperwork and Permits When Needed

If the city requires notification, your arborist will prepare the form with details such as trunk diameter (DBH), species, photos, and a site sketch. This ensures compliance and avoids delays.


3. Safe Tree Removal or Pruning

Trained crews utilize proper rigging, protective gear, and safe methods to safeguard your roof, driveway, and surrounding areas. This is where certification, training, and insurance coverage are most important.



4. Cleanup and Stump Grinding

After removal, you can choose stump grinding or complete stump removal. If you plan to plant new vegetation or install hardscape, utilities should be marked in advance through Georgia 811 to prevent costly damage.

When to Choose a Certified Arborist in Marietta

Hazard Concerns

If you notice cavities, internal decay, or a leaning trunk that is leaning toward your home, driveway, or power lines, a certified arborist can assess the risk and recommend safe action.

Work Near Structures or Utilities

Tree projects close to roofs, driveways, or power service lines require specialized rigging and protective methods that certified professionals are trained to handle safely.

City Paperwork and Permits

Marietta often requires official notifications or permits for tree removals. A certified arborist can prepare the necessary forms, photos, and site sketches to keep your project compliant.

Insurance and Storm Recovery

After storm damage, insurance companies may request professional documentation. A certified arborist provides records that protect your claim and help ensure repairs are covered.

Large or Complex Projects

Multi-tree removals or projects involving heavy rigging and planning require experience and advanced equipment. Certified arborists manage these jobs to minimize property damage and liability.

How to Check Arborist Credentials in 60 Seconds

Certification Number

Every certified arborist has a credential ID with an expiration date. Always confirm that it is valid and up-to-date before making a hiring decision.

Proof of Insurance

Request a current Certificate of Insurance (COI) that includes both workers’ compensation and general liability coverage. This documentation protects you from liability in the event of an accident.

Written Plan

A professional arborist should provide a detailed scope of work that references Marietta’s permit requirements when removal is involved. This ensures compliance and prevents costly project delays.

Local References

Request references from past clients in your neighborhood. Speaking with nearby homeowners gives you confidence in the arborist’s reliability and the quality of their work.

Peace of Mind

A true professional will provide documentation quickly and without hesitation. If details are vague or missing, consider it a warning sign to look elsewhere.

Frequently Asked Questions

  • Do I need city approval to remove a hazardous tree?

    Yes. If a tree is dead, dying, or poses a danger, Marietta often requires a Notification of Tree Removal. City staff will verify the condition, and a certified arborist can prepare photos and documentation.

  • What about healthy trees on private residential lots?

    Healthy tree removals may not always require approval, but rules often apply when tied to development or grading. To avoid violations, contact Marietta Development Services or have an arborist review your property first.

  • Can I trim branches hanging over my property line?

    You can cut limbs that extend onto your side of the property, but you cannot trespass or damage the tree itself. A certified arborist ensures pruning is safe, legal, and healthy.

  • Does Cobb County require a permit?

    In unincorporated Cobb County, large-scale removals or land-disturbance projects may need a timber harvest permit or Site Plan Review. Always confirm requirements with the County Development Office or let an arborist coordinate.
