Delaware Landscaping Contractor License Requirements (2026)

Delaware does not issue a state-level landscape contractor trade license. Every landscape business must register with the Delaware Division of Revenue for a Business License under 30 Del. C. §2301 (typical landscaper classification fee $75 plus 0.3983% gross receipts tax). Any commercial application of pesticides or herbicides requires a Commercial Pesticide Applicator license from the Delaware Department of Agriculture (DDA) Pesticides Section under 3 Del. C. Chapter 12. Tree work beyond incidental landscape pruning requires a separate Delaware Tree Expert license issued by DDA Forest Service under 3 Del. C. Chapter 10.

Regulatory Body Profile

Licensing for this trade is governed by Delaware Division of Professional Regulation (DPR), the agency that issues and regulates the credential under Delaware Code Title 24 (Professions and Occupations); Title 30 (Business License, Division of Revenue). The Delaware Division of Professional Regulation administers the trade licensing boards for electricians, plumbers, HVACR, and master pipefitters. Delaware does not issue a state general contractor license — any person doing contracting work in Delaware must instead hold a Delaware Business License from the Division of Revenue.
