Addy-Sea Inn

John and Jennie Addy, summer migrants from Pittsburgh, built the Addy Sea in 1901 as a family retreat on a corner lot at what is now Ocean View Parkway and North Atlantic Avenue in Bethany Beach, one of the town's earliest oceanfront homes. John Addy worked as a plumber, and the house was reportedly the first in the area wired for gaslight and fitted with indoor plumbing; some later accounts date the finished, expanded house to 1904. The Victorian-era structure took its present form with cedar-shingle siding and gingerbread trim, and its tin ceilings and fireplaces have since been restored.

Coastal storms forced two relocations: after a 1927 storm, the house was moved a block west of its original footing using manpower, mules, and log rollers, and a smaller structure sold off the property (Addy #3) was later donated and moved again, becoming Bethany Beach's Nature Center in 1998. The building's foundation was compromised but the structure remained standing through a major 1962 coastal storm. During the Great Depression the Addy children began renting rooms to make ends meet, starting the property's transition from private home to lodging house.

Leroy T. Gravatte III purchased the Addy Sea from the Addy family in 1974 and carried out renovations over subsequent decades, retaining the Victorian character while adding modern amenities. Jeff and Sherene Gravatte took over as innkeepers in 2016. Eventide Hospitality acquired the operating business in 2023 while the Gravatte family retained ownership of the property; the inn joined the Select Registry hospitality association on April 1, 2025, and was named a Best of Delaware honoree for Best B&B/Inn by Delaware Today in 2022.
