Perini Tree Contractors

Cohasset's harbor, salt marshes, coastal banks, and rocky shoreline make it heavily regulated for landscaping. Work near these resources falls under the Wetlands Protection Act and the state's coastal resource-area rules, so the Cohasset Conservation Commission reviews grading, clearing, and hardscape near water — typically through a Notice of Intent, with coastal-bank and marsh work scrutinized closely. Many lots sit in FEMA flood zones with added rules, and historic-district properties may need design review. Retaining walls over four feet generally require a building permit and engineered plans; ledge removal or blasting carries its own permitting. Check with Conservation before any coastal-edge work.

Cohasset landscaping prices are among the highest on the South Shore — ledge, salt-tolerant material, coastal access, and the town's estate-scale projects all push costs up. Routine mowing runs about $60–$110 per visit, spring cleanups $400–$900, and fall cleanups $450–$1,200. Mulch and amendment run roughly $90–$150 per yard installed. Irrigation for a sizable lot runs $5,500–$12,000. A bluestone or granite patio commonly lands at $12,000–$25,000, while a full coastal design-build with stonework, salt-tolerant plantings, and outdoor living space ranges from about $35,000 well into six figures.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential landscaping work; ask for the registration number and check it before paying a deposit.
