ADU builder, excavation, and site work for Sanford homeowners and investors. Based 25 minutes away in West Newfield, Maine, Langone Site Services delivers turn-key ADU builds, custom homes, excavation, and septic systems across York County.
Sanford is the largest city in York County and one of the fastest-growing ADU markets in southern Maine. With Mousam Lake rentals, the Sanford Regional Airport expansion, and a revitalized downtown along Main Street, demand for detached accessory dwelling units and in-law suites has climbed steadily since Maine's LD 2003 passed.
A 600-800 sq ft ADU on a Sanford single-family lot typically rents long-term for $1,500-$1,900/month and short-term for $2,200-$2,800/month near Mousam Lake. We've built turn-key ADUs in Sanford neighborhoods from South Sanford to Springvale with permitting handled end-to-end.
We own our full excavation fleet — John Deere excavators, grading equipment, and dump trucks — so Sanford projects don't wait on rental equipment. Typical jobs: foundation dig, septic installation, driveways, drainage remediation, and site prep for new ADU and home builds.
Sanford falls under Maine's LD 2003 which requires the city to permit at least one ADU on most single-family lots. Sanford's zoning office has become faster at approving ADU plans when they arrive complete — we package every build with site plan, elevations, septic load calc, and DEP erosion control plan.
