Premium ADU construction and coastal site work for Kennebunk property owners. Based 35 minutes away in West Newfield, Maine, Langone Site Services delivers turn-key ADU builds, custom homes, excavation, and septic systems across York County.
Kennebunk and Kennebunkport form one of Maine's most valuable coastal real-estate markets. Lot values routinely exceed $300k before any vertical construction, making ADUs and in-law additions an especially strong investment for owners of larger parcels in Lower Village, West Kennebunk, and along Route 35.
Short-term rental economics in Kennebunk are some of the strongest in the state — a finished 1-bed ADU can earn $3,500-$5,000/month during summer peak. We build to a premium interior spec (LVP or hardwood, granite, Andersen windows, on-demand hot water) that holds up to coastal rental wear and Kennebunk's discerning tenant pool.
Kennebunk lots often present unique site challenges — tight setbacks, mature trees, high water tables near the Mousam River, and tight access off narrow village streets. Our owned small-footprint excavator fleet handles those lots where larger contractors need to rent specialty equipment.
Kennebunk permits ADUs under Maine LD 2003 but requires review by the planning office. Lots in the shoreland zoning district (within 250 ft of the Mousam River or tidal waters) carry additional DEP requirements — Langone carries Maine DEP Erosion and Sediment Control certification, which is usually mandatory for shoreland work.
