After forming your LLC and getting your EIN, licensing is the next piece most contractors get wrong. The rules vary by state, county, trade, and service type. Most operators either over-comply, under-comply, or just guess.
This guide maps the full licensing landscape for exterior home service contractors. What you actually need, what different license types cover, trade-specific requirements, and what happens when you skip something you shouldn’t have.
Most exterior home service contractors need at minimum a local business license from their city or county. Trade-specific licenses vary by state and service type. Chemical applications require a pesticide applicator license in virtually every state. Check your state’s requirements before your first paid job.

License Lookup by State →The Two Types of Licenses Most Contractors Need
Contractor licensing operates on two separate tracks that most new operators confuse. Understanding the difference prevents gaps that can cost you real money.
1. Business License (Local)
A general business license is issued by your city or county. It gives you the right to operate a business in that jurisdiction. It has nothing to do with trade skills — it is purely administrative. Most jurisdictions require it. Fees run $25 to $150 per year and it renews annually.
Forming an LLC does not replace a local business license. They come from different agencies and serve different purposes. You need both.
2. Contractor or Trade License (State)
A contractor license is a state-issued credential that verifies competency in a specific trade. Requirements vary dramatically — some states require formal exams and experience hours, others require only registration and a fee, and some trades have no state licensing requirement at all.
The key question is not whether a license exists for your trade — it’s whether your state requires it for paid commercial work.

Licensing Requirements by Trade
Here’s where each major exterior home service trade stands on licensing. These are general patterns — always verify current requirements with your state’s licensing board or department of commerce.
Basic mowing typically requires only a local business license. Chemical applications — fertilization, weed control, pest treatments — require a pesticide applicator license in almost every state.

Licensing requirements in this industry are all over the map. Some states license everything. Others license almost nothing. The same service might require a $500 exam in one state and a $75 registration in the next.
| Requirement Level | What It Means | States (Examples) |
|---|---|---|
| No state license | Local business license only required for most trades | TX, FL, CO, WY (for many trades) |
| Registration only | File with the state, pay a fee, no exam required | VA, TN, MN, WI (varies by trade) |
| Exam required | Pass a competency test administered by the state | CA, NC, SC, NV, MD (varies by trade) |
| Experience + exam | Document field hours and pass a written exam | GA, AZ, MS, AL (varies by trade) |

Permits — Different from Licenses
Licenses authorize you to operate a business. Permits authorize specific jobs or installations. The distinction matters because many contractors who are properly licensed still get caught operating without required job-specific permits.
Common permit requirements for exterior home service work:
- Retaining walls — most municipalities require a permit for walls over a certain height, typically 2 to 4 feet
- Fencing — permits often required for new fence installation, especially in regulated neighborhoods
- Irrigation systems — many jurisdictions require permits for new irrigation installs
- Drainage modifications — grading and drainage work that affects runoff may require permits
- Outdoor structures — pergolas, gazebos, and covered patios often require building permits

Working in Multiple Cities or Counties
If your service area crosses city or county lines — which is common for most growing operations — you may need separate business licenses in each jurisdiction. Some counties are structured so that a county license covers unincorporated areas, while incorporated cities within that county require their own license.
The practical approach: research each jurisdiction where you work regularly. Budget $25 to $100 per jurisdiction per year. Keep a renewal calendar so nothing lapses.

What Happens If You Skip Licensing
Operating without required licenses isn’t just a legal risk — it creates practical business problems that compound over time.
Fines and stop-work orders are the obvious ones. But unlicensed contractors also face voided contracts (you may be unable to collect payment in court), denied insurance claims, and personal liability for job-site incidents that would otherwise be covered. In some states, knowingly operating without a required license is a criminal misdemeanor.

Special Certifications Worth Having
Beyond required licenses, several voluntary certifications significantly improve your marketability with commercial clients and HOAs.
- ISA Certified Arborist — the industry standard for tree care professionals. Required or strongly preferred by most commercial and municipal tree work contracts.
- TCIA Accreditation — Tree Care Industry Association credential for tree service companies. Signals safety standards and professional practices.
- EPA RRP Certification — required for any work on pre-1978 properties that may disturb lead-based paint. Applies to more exterior contractors than most realize.
- ICPI Certification — Interlocking Concrete Pavement Institute credential for hardscaping installers. Valued by commercial clients and carries a premium.

Most exterior home service contractors need at minimum a local business license, and many need additional state or trade-specific credentials depending on what services they offer. The cost of getting licensed is a fraction of the cost of operating without one when something goes wrong. Research your specific requirements, get compliant before your first paid job, and build a renewal system so nothing lapses mid-season.
Frequently Asked Questions
Do I need a license to mow lawns?
For basic mowing, most states do not require a specific contractor license. However, most cities and counties require a general business license to operate commercially. If you apply any fertilizers, herbicides, or pest control products, a pesticide applicator license is required in virtually every state regardless of whether mowing itself requires a license.
What is the difference between a business license and a contractor license?
A business license is a general permit from your city or county authorizing you to operate a business in that jurisdiction. A contractor license is a state-issued credential that verifies trade competency. They serve different purposes, come from different government entities, and many contractors need both. Forming an LLC does not replace either one.
How do I find out what licenses I specifically need?
Start with your state’s contractor licensing board or department of commerce website. Search your trade specifically — requirements vary by trade even within the same state. Then check your city and county websites for local business license requirements. Our state-by-state guide and license lookup tool are good starting points but always verify with the issuing agency directly.
What happens if I work without a required license?
Consequences include fines, stop-work orders, voided contracts, denied insurance claims, and personal liability for job-site incidents. In some states, knowingly operating without a required license is a criminal misdemeanor. The penalties vary by state and trade but are consistently more expensive than getting licensed in the first place.
Do I need a separate license for every city I work in?
Potentially yes. Many cities require their own business license separate from state licensing and separate from neighboring cities or county licensing. If you regularly work in multiple jurisdictions, research each one. The cost is typically $25 to $100 per city per year — manageable, but easy to miss if you don’t track it.
