YORK HARBOR, Maine — Just what would Fanny Chapman have thought of Rod Stewart’s infamous disco era anthem “Do Ya Think I’m Sexy?’’? A few minutes walk from where the Gilded Age socialite summered in York Harbor many decades ago, Rod Stewart impersonator Rick Larrimore, suitably swaggering and shaggily coifed, cajoled the crowd at the York Harbor Inn’s Patriots’ Day weekend dinner show. It was his third “Rod’’ show there, and the Boston-based singer has packed the place every time.

Chapman might have been thrilled, too. Apparently, Fanny and her sisters, who Henry Adams’s used as models for characters in his novel, “Democracy,’’ hobnobbed with the glitterati and literati of the day, including at their York Harbor home, which is now the York Harbor Inn’s latest addition.

Just as there are three Yorks — York Village, York Harbor, and York Beach — known rather regally, as it turns out, as The Yorks, there are several parts to this inn. The Chapman Cottage came into the set in 2013, making it the sixth building.

Entering York Harbor, the quietest of the Yorks, from the south on Route 1A, the sunny-yellow painted Chapman mansion perches lady-like on a gentle knoll’s sweeping lawn. Summer homes and grand hotels once dotted this appealing stretch of southern Maine coastline. “The Yorks were full of Victorian hotels back then,’’ says the York Harbor Inn’s innkeeper, Garry Dominguez. “Most of those burned down, unfortunately. But it was known as the Newport of the North Country.’’

Dominguez bought the main inn, half a mile down Route 1A from the Chapman Cottage, with his twin brothers in 1979: “It had been empty for three years and was in rough shape,’’ the New Jersey native recalls.

Dominguez was drawn to the area for the same reasons people still pour in: “It’s the natural beauty that draws visitors,’’ he says. “The natural beauty of the ocean; and the beaches. Also, The Yorks are very well preserved, not overly built up. Building ordinances restrict building new hotels, so The Yorks, and York Harbor in particular, remain as they were.’’

He jokes that the ordinance cuts down on his competition. In fact, he is the competition: what comes under the York Harbor Inn umbrella expanded from the original 10 rooms with shared bathrooms — “That was very much accepted in the early 1980s,’’ shrugs Dominguez — to six different inns with 62 rooms. Now, each has a private bathroom, even in the old inn.

After the addition of the Yorkshire House and Harbor Cliffs, the Harbor Hill Inn opened in 2002, on what was part of the Hartley Mason estate. The old buildings were in teardown condition and Harbor Hill is the only newly built inn in the collection. The rest of the estate, across Route 1A from the main inn, had been leveled in the early 1990s, opening up the sea view to all, and transforming York Harbor.

“The will of Hartley Mason said that if no direct descendants succeeded him, the land by the cliff should be turned over to the town for a park,’’ says Dominguez. The idyllic, picturesque Hartley Mason Reserve frames the ocean directly in front of his inns: “It was great for the town and great for us,’’ he agrees.

Before the Chapman came into the fold, the adjacent 1730 Harbor Crest Inn was created from another summer cottage, known as the Mercer Mansion, and built by Fanny’s relative, Henry Chapman Mercer, a paleontologist. Mercer also founded the Moravian Pottery and Tile Works in Doylestown, PA, the family’s ancestral home. Moravian Pottery’s beautiful Arts and Crafts tiles were used in the Pennsylvania State Capitol’s mosaic floor, Grauman’s Chinese Theater in Hollywood, and the Casino at Monte Carlo in Monaco. They can be seen in the Harbor Crest’s fireplace surrounds in the dining room and lounge.

The Chapman and Harbor Crest (the latter is pet-friendly) offer understated boutique luxury (private decks, Jacuzzis, fireplaces), and the Chapman’s Tavern restaurant, which has fireplace and deck dining, allows longtime chef, Gerald Bonsey, who joined in 1980, to go left-field. “The menu is more traditional New England in our main inn,’’ says Dominguez. “The Chapman is a more trendy menu, more specialized; it’s a nice option for us to have when visitors and even locals are looking for something different.’’ But the original inn’s creaky New England charm and its 1637 Restaurant, named to honor the building’s history, and the Ship’s Cellar Pub, decked out like a ship’s cabin, remain very popular.

“It is our busiest by far,’’ Dominguez says of the Ship’s Cellar. “It was a horse stable back in the late 1700s, or early 1800s. Two of the stables had been converted into cocktail areas and it had a horseshoe bar in the lower room.’’ Apparently, just like Rod, it was a big hit in the 1970s. “Oh yes,’’ says Dominguez. “There’s plenty of stories there.’’
