Dartmouth's extensive coastline and wetlands make Conservation Commission review a central part of many projects. Work within 100 feet of a wetland, salt marsh, or coastal bank — and within the broader regulated zones along Buzzards Bay — falls under the Wetlands Protection Act and usually requires a Notice of Intent for grading, clearing, or hardscape. Retaining walls over four feet need a building permit and engineered plans, pools require permits and fencing, and coastal sites may face additional erosion-control and stormwater conditions. Allow generous lead time for shoreline filings.

Routine maintenance in Dartmouth runs roughly $50–$95 per mow given larger lots, with spring cleanups $300–$800 and fall cleanups $350–$1,000. Mulch is about $90–$140 per yard installed. Irrigation for a sizable lot typically runs $5,000–$10,000. Coastal hardscape — bluestone and stone patios built to handle exposure — commonly lands at $10,000–$20,000, and full design-build projects on large rural or waterfront lots range from about $25,000 to well past $100,000, with shoreline permitting adding to both cost and timeline.

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.
