The State Street Inn is located in a historic Tudor Revival home at 228 N State Street. The home is part of the Victorian Dover Historic District, listed on the National Register of Historic Places. It was built circa 1911 for Mr. and Mrs. Walt Conaway.

Later, it was the home of Simeon Selby Pennewill (1867-1935), who served as Delaware's Governor from 1909-1913. Governor Pennewill was elected as a 41-year-old bachelor, although he was married twice later in life. Before serving as Governor, he served two terms in the Delaware State Senate. He was educated nearby at the Wilmington Conference Academy, which later became Wesley College.

Modern Day:

At some point (date unknown), the home was converted to a bed-and-breakfast called the "Tudor House." Sadly, the inn eventually closed and fell into disrepair.

In 2003, the home was purchased by Mike and Yvonne Hall. From 2003-2005, the home was extensively renovated and returned to bed-and-breakfast use. The kitchen was updated, and many of the home's original features were restored.

In 2017, the Inn was sold to its current owners, the Breukelman family.

Today, the home retains its historic charm. The State Street Inn is nestled among a diverse collection of stately homes, most constructed during the late 19th or early 20th centuries.
