How to Start a Landscaping Business in Maryland (2026)

Last updated: February 25, 2026

Starting a landscaping business in Maryland is more regulated than most states because you’re dealing with three separate licensing agencies. The Maryland Home Improvement Commission (MHIC) requires a license for any landscaping work beyond basic mowing – anything where “a shovel goes in the ground” counts as home improvement. The Maryland Department of Agriculture (MDA) requires separate certifications for pesticide application and fertilizer application (Maryland’s Chesapeake Bay fertilizer law is unique in the country). And if you do tree work, the Department of Natural Resources (DNR) requires a Licensed Tree Expert credential. This guide breaks down every requirement from official Maryland sources so you can navigate the licensing maze and start legally.

How to Start a Landscaping Business in Maryland (Step by Step)

Step 1: Form Your Business Entity

Register an LLC with the Maryland State Department of Assessments and Taxation (SDAT). Filing costs $100 by mail or $150 online through the Maryland Business Express portal. Online filings are typically processed in 1-2 business days.

Apply for a free federal EIN from the IRS (immediate online). You need this to open a business bank account, hire employees, and apply for your MHIC license.

Important: Maryland LLCs must file an Annual Report with SDAT by April 15 each year ($300). Miss the deadline and your LLC will be forfeited.

Step 2: Get Your MHIC License

The Maryland Home Improvement Commission (MHIC) regulates landscaping as a home improvement trade. If your work goes beyond basic lawn mowing – planting, grading, installing hardscapes, irrigation, retaining walls – you need an MHIC license. The rule of thumb: if a shovel goes in the ground, it’s home improvement.

Lawn mowing only is exempt from MHIC licensing. If you only mow, trim, and edge, you do not need this license.

MHIC license requirements:

Experience: 2 years of verifiable trade experience in landscaping/home improvement
Exam: Pass the PSI home improvement exam (~$63 exam fee)
Insurance: $50,000 minimum general liability insurance (must be on file with MHIC)
Application fee: $281.25
Processing fee: $22.50
Guaranty fund contribution: $100
Total initial cost: ~$467
Renewal: Every 2 years, $456.25

Step 3: Get Pesticide Applicator Certification

If you apply pesticides (herbicides, insecticides, fungicides) for hire, you must be certified by the Maryland Department of Agriculture (MDA). This is separate from and in addition to your MHIC license.

Certification requirements:

Exams: Pass the core exam plus relevant category exams (Category 3A for ornamental/exterior pest control, Category 3C for turf pest management) – 70% passing score required
Individual certification: $75/year, plus $25/year for each additional category
Business license: $150/year (required for the business entity applying pesticides)
Required insurance: $100,000/$300,000 bodily injury and $15,000/$30,000 property damage liability

Step 4: Get Professional Fertilizer Applicator Certification

Maryland has a unique fertilizer law driven by Chesapeake Bay protection that no other state matches. If you apply fertilizer commercially, you must obtain a Professional Fertilizer Applicator certification from MDA. This is a separate certification from the pesticide license.

Certification costs approximately $100/year. You must pass a certification exam covering Maryland’s strict application rules:

Nitrogen limit: Maximum 0.9 lbs of nitrogen per 1,000 sq ft per application
Phosphorus ban: Phosphorus is prohibited unless a soil test shows a deficiency
Seasonal blackout: No fertilizer application between November 15 and March 1
Buffer zones: 10-15 foot setback from waterways required

These rules apply to every commercial application. Violating them can result in fines and loss of certification.

Step 5: Get Licensed Tree Expert Credential (If Doing Tree Work)

If you perform tree work for compensation – pruning, removal, diagnosis, treatment – you must be a Licensed Tree Expert through the Department of Natural Resources (DNR). Working on trees without this license is illegal in Maryland.

Requirements:

Education: 2 years of college (with coursework in arboriculture, forestry, or related fields)
Experience: 1 year of practical tree care experience
Exam: DNR tree expert exam at the Tawes State Office Building in Annapolis
Cost: $30 initial license fee, $20/year renewal
Continuing education: 8 CEUs per 2-year cycle

Many landscaping businesses skip tree work initially and subcontract it to a licensed tree expert until they can get their own credential.

Step 6: Get Insurance Coverage

General liability insurance is required for MHIC licensure ($50,000 minimum), but you should carry at least $1 million per occurrence for adequate protection. Landscaping businesses face higher liability risk than many trades due to property damage, equipment hazards, and chemical applications.

Workers’ compensation insurance is mandatory in Maryland for any business with 1 or more employees. Maryland’s threshold is lower than many states – there is no exemption for small employers. You must have coverage before your first employee starts work.

If you apply pesticides, MDA requires separate insurance minimums: $100,000/$300,000 bodily injury and $15,000/$30,000 property damage.

Step 7: Set Up Employer Tax Accounts (If Hiring)

Register with the Maryland Comptroller for income tax withholding and with the Division of Unemployment Insurance for UI tax. Report new hires to the Maryland State Directory of New Hires within 20 days.

Sales tax note: Landscaping labor services are generally not subject to Maryland sales tax. However, if you sell materials separately (plants, mulch, pavers sold as goods), those are taxable at the 6% state rate. If your service includes materials as part of a lump-sum contract, you pay sales tax on your cost of materials.

Frequently Asked Questions

Do I need a license to start a landscaping business in Maryland?

Yes, in most cases. If your work goes beyond basic lawn mowing – planting, grading, hardscaping, irrigation – you need an MHIC license from the Department of Labor. Lawn mowing only is exempt. If you apply pesticides or fertilizer, you need separate MDA certifications. Tree work requires a DNR Licensed Tree Expert credential.

Can I just mow lawns without an MHIC license?

Yes. Lawn mowing, trimming, and edging are exempt from MHIC licensing. However, as soon as you put a shovel in the ground – planting, installing beds, grading, building retaining walls – you’re performing home improvement and need the MHIC license.

What is the Maryland fertilizer applicator certification?

Maryland’s Chesapeake Bay protection law requires anyone applying fertilizer commercially to hold a Professional Fertilizer Applicator certification from the Department of Agriculture. This is unique to Maryland. Key rules include a max of 0.9 lbs nitrogen per 1,000 sq ft, a ban on phosphorus unless soil tests show deficiency, and a seasonal blackout from November 15 through March 1.

Do I need workers’ compensation insurance for my landscaping business?

Yes, for any business with 1 or more employees. Maryland requires workers’ comp starting with your very first employee – there is no small-employer exemption. Sole proprietors with no employees are not required to carry it but can opt in voluntarily.

Are landscaping services taxable in Maryland?

Landscaping labor is generally not taxable. Maryland does not charge sales tax on landscaping service labor. However, if you sell materials separately (plants, mulch, stone), those goods are taxable at the 6% state rate. In lump-sum contracts that include materials and labor, you pay sales tax on your cost of materials.

How much does it cost to start a landscaping business in Maryland?

A solo landscaping business (basic services, no tree work) can start for around $1,400-$3,000, including LLC formation ($100-$150), MHIC license (~$467), liability insurance ($500-$1,200/year), and basic equipment. Add pesticide, fertilizer, and tree expert certifications plus employees, and costs rise to $2,500-$5,000+ before equipment.
