Oklahoma Landscaping Contractor License Requirements (2026)

Oklahoma does not issue a state-level landscape contractor trade license. The mandatory state credential is a Commercial Pesticide Applicator certification from the Oklahoma Department of Agriculture, Food, and Forestry (ODAFF) Consumer Protection Services under 2 O.S. §3-82 for any commercial pesticide application. The Oklahoma Water Resources Board (OWRB) regulates large irrigation withdrawals. Tulsa, Oklahoma City, and Norman require local landscape contractor registration.

Regulatory Oversight

Under Oklahoma Statutes Title 59 §1000 et seq. (plumbing) and §1680 et seq. (electrical and mechanical/HVAC), Oklahoma Construction Industries Board (CIB) is the body that issues this license and enforces compliance with it. The Oklahoma Construction Industries Board licenses individual journeymen and contractors for the electrical, plumbing, and mechanical (HVAC/refrigeration) trades statewide, administers PSI examinations, and conducts disciplinary proceedings. Oklahoma has no statewide general contractor license — general contracting is regulated by individual cities.
