The St. Augustine, Florida, house claimed to be the oldest continuously inhabited house in the United States is the González–Álvarez House.
Also called the Oldest House, it stands at 14 St. Francis Street in St. Augustine. Its present structure has a complex construction history, with the earliest surviving portions generally dated to about 1723, though archaeological evidence indicates that the site was occupied earlier.
The building reflects St. Augustine’s changing colonial history. Spanish construction techniques, including coquina masonry, were later modified during British and second Spanish periods. Early documented residents included Tomás González y Hernández and his family; the property later passed to Joseph Peavett and Gerónimo Álvarez.
The wording is sometimes misunderstood: the claim concerns a surviving historic dwelling and its long-occupied site, not an unbroken record of residents in the exact same building. It is now a house museum operated by the St. Augustine Historical Society and became a National Historic Landmark in 1970.
