Maryland Landscaping License Requirements

Maryland treats landscaping and improvements to land adjacent to a residence as home improvement. A contractor offering or performing that work for an owner needs a Maryland Home Improvement Commission (MHIC) contractor license; the statute does not establish the $1,000 threshold previously stated here. Pesticide application and fertilizer application are separate regulated activities. A business applying pesticides for hire must meet the Maryland Department of Agriculture (MDA) pesticide business-licensing and certified-applicator requirements. Lawn-care professionals hired to apply fertilizer to non-agricultural turf must be certified by MDA or work under the direct supervision of a certified person, and the employing business must be licensed. These MDA credentials apply only when the landscaping business performs the regulated application work.

Regulatory Body

Maryland Department of Labor — Division of Occupational and Professional Licensing (MD DOL) administers the credential or scope-specific rules discussed here under Maryland Code, Business Regulation and Business Occupations Articles. Whether that pathway applies depends on the work scope and conditions explained below. The Maryland Department of Labor houses the occupational boards that license home improvement contractors, master electricians, plumbers, and HVACR contractors statewide, adopts technical codes by reference, and conducts disciplinary proceedings.

Eligibility Requirements

Applicants must be at least 18 years old. Applicants must provide a Social Security Number. No Maryland residency requirement.

Good moral character

For MHIC, applicants with a home-improvement-related misdemeanor or a felony must provide conviction records; MHIC evaluates the conviction and fitness factors described in its applicant FAQ.

Background investigation

MHIC’s current contractor requirements call for conviction records when applicable; a fingerprint requirement was not confirmed on the official MHIC requirements page.

Experience and Education

Plan to substantiate 2 years of MHIC requires at least two years of home-improvement, construction, and/or related education. If the business applies pesticides or fertilizer, meet the separate MDA qualification, certification, supervision, and business-license requirements that apply to that activity. with hard records. Payroll, tax, project logs, and supervisor verification are what the board relies on when it reviews the claim.

Accepted proof of experience or eligibility

MHIC documentation of qualifying experience or related education and financial solvency
MDA applications and supporting documents when applying pesticides or fertilizer for hire

Education substitution

MHIC accepts related education as part of the required two years of home-improvement, construction, and/or related education; confirm how MHIC will evaluate a particular program.

Exam Requirements

Testing provider or authority: PSI Services LLC (MHIC); Maryland Department of Agriculture for pesticide and fertilizer credentials when applicable. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

MHIC contractor examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
MDA pesticide examinations required for the activity and category — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
MDA Professional Fertilizer Applicator certification examination, when fertilizer is applied — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: Confirm the current PSI and MDA examination fees before registering. MDA’s 2026 Professional Fertilizer Applicator exam application lists a $100 certification fee.

Retake policy: For MHIC, wait 30 days after a first failed attempt and 60 days for later requests; the exam fee is due for each attempt. Confirm pesticide and fertilizer retake rules with MDA.

Insurance and Bonds

The cited state source set does not require a contractor license surety bond for this credential. Contractors should still confirm project-specific bond, permit-bond, or public-works bond requirements before bidding.

General liability

MHIC requires at least $500,000 in general liability insurance for original and renewal contractor licensure. MDA coverage requirements are separate when the business performs regulated pesticide or fertilizer work.

Workers' compensation

Under Labor and Employment Article §9-402, each employer must secure compensation for covered employees through authorized insurance, an eligible self-insurance arrangement, or another statutory method.

Additional financial requirements

MHIC requires proof of financial solvency based on business scope and size, assets, liabilities, credit report, and net worth. An applicant that does not meet its guidelines may use a surety bond or indemnitor. MHIC also collects Guaranty Fund assessments.

Fee Schedule

Step-by-Step Application Roadmap

Confirm whether the offered landscape work is home improvement. Landscaping and improvements to land adjacent to a residence are within the statutory MHIC definition. Confirm the project’s scope before contracting.
Document MHIC experience, related education, and financial solvency. Prepare two years of qualifying home-improvement, construction, and/or related education, plus the financial materials MHIC requests.
Secure MHIC liability insurance. Maintain at least $500,000 general liability coverage for original and renewal MHIC licensure.
Pass the MHIC contractor examination. All MHIC contractor applicants must pass the PSI-administered examination before applying.
Submit the MHIC contractor application. Use MHIC’s current fee schedule: original contractor application, processing, and Guaranty Fund charges currently total $403.75 before the PSI exam and insurance.
Add MDA pesticide licensing only if applying pesticides. A landscaping business that applies pesticides for hire must meet the separate MDA business-license and certified-applicator requirements.
Add MDA fertilizer certification and business licensing only if applying fertilizer. Lawn-care professionals applying fertilizer to turf must be certified or directly supervised by a certified person; the business employing them must be licensed by MDA.
Follow site-specific environmental and local requirements. Confirm applicable local permits, erosion/sediment controls, and Maryland nutrient-management restrictions for the actual site and scope.

Common Filing Mistakes

Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a Maryland Landscaping application.

Using an unsupported dollar threshold

Landscaping and improvements to land adjacent to a residence are listed in Maryland’s home-improvement definition. Do not rely on the former $1,000 threshold; verify scope with MHIC before contracting.

Missing MHIC financial-solvency review

MHIC requires more than experience and an exam: it reviews financial solvency and may require a surety bond or indemnitor when its guidelines are not met.

Applying pesticides without the MDA path

Pesticide application for hire has separate MDA business and certified-applicator requirements. Add them only when the landscaping business performs that regulated work.

Applying fertilizer without certification or business licensing

MDA requires lawn-care professionals applying turf fertilizer to be certified or directly supervised by a certified person, and it requires the employing business to be licensed.

Relying on stale environmental dates or thresholds

Nutrient-management, erosion/sediment, and local-permit requirements can turn on the site and scope. Use current MDA, MDE, and local authority materials rather than a generic statewide project threshold.

Frequently Asked Questions

Do I need an MHIC license for landscape work?

MHIC and Maryland law list landscaping and improvements to land adjacent to a residence as home improvement. A contractor offering or performing that work for an owner needs an MHIC license. The statute does not establish the $1,000 threshold previously stated here.

What is the Professional Fertilizer Applicator credential?

MDA says lawn-care professionals hired to apply fertilizer to turf must be certified or work under the direct supervision of a certified person. The business employing certified fertilizer applicators also must be licensed. These rules apply when the business applies fertilizer, not to landscaping work that does not include fertilizer application.

Do landscape companies need pesticide licensing?

Only if they apply pesticides for hire. MDA’s pesticide program separately regulates commercial pesticide businesses, certified applicators, and employee registration. Confirm the category and company requirements with MDA for the pesticides and work offered.

Are there special Chesapeake Bay rules?

Maryland’s Lawn Fertilizer Law imposes nutrient-application restrictions and requires certification and business licensing for professionals who apply turf fertilizer. MDA’s current Turfgrass Nutrient Management Program is the appropriate source for current dates, restrictions, reports, and penalties.

How often does MHIC renew?

MHIC licenses run for two years from original issuance. MDA pesticide and fertilizer credentials have their own renewal and recertification schedules; do not assume the MHIC cycle applies to them.
