STATE LICENSE
ConditionalMassachusetts Department of Agricultural …
OCABR's job chart lists routine landscaping, patios, and landscape masonry with no public-safety threat as requiring no CSL, no HIC registration, and no building permit. Exterior retaining walls require HIC registration on owner-occupied residential jobs, and a CSL and building permit when greater than 4 feet high; fences need a permit and CSL only at seven feet or higher.
Lawn care and landscape crews that apply pesticides — including herbicides — for hire need MDAR credentials: the Applicator (core) License for general-use pesticides ($75 exam registration + $28 online exam fee, $100 license) and a Commercial Certification for restricted-use pesticides ($125 exam registration, $150 license, two years of experience). Credentials renew every December 31 and require liability insurance with a pollution-exclusion endorsement.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide licensing is statewide through MDAR. Retaining walls, fences, and grading may need local permits and zoning review; the building official decides when a wall needs a CSL.
The local offices section below names the exact permit desk for every Massachusetts county on file.

MDAR's bulletin says the core Applicator License is usually held by people in lawn care, landscape, and ornamental tree care who apply general-use pesticides for hire.
All applicator credentials expire December 31; core licensees need 6 contact hours and commercial certifications 12 per category every three years.
Exterior retaining walls greater than 4 feet need a CSL and building permit, per OCABR's guidance chart.
