Louis Johnson Building

You’ll find the Louis Johnson Building right in the heart of downtown Largo, Florida. It’s one of those places that’s soaked up a century’s worth of stories since Louis Steele Johnson put it up in 1911. Back then, Johnson—who wasn’t just a local developer but also served as mayor twice—had big plans. He wanted a spot that mixed business and lodging, something that would help Largo grow into the kind of town he pictured.

On the ground floor, you’d have seen all sorts of activity: the Largo Hardware Company, Johnson’s own drug store, and even an ice cream parlor. Upstairs, his wife ran the Pinellas Hotel. There were ten guest rooms, and everyone shared the bathrooms. It was simple, but it worked. Don’t forget to check out this place in Largo too.

The building itself is a bit unusual—poured concrete blocks, shaped kind of like a trapezoid, topped off with a flat roof. That style, cast stone block, used to be everywhere in Florida, but now it’s pretty rare. The outside stands out too, with its two-story veranda, heavy cornice, and that hip roof—details you don’t see much these days.

But Johnson didn’t stop at just the building. He made a huge difference in Largo by setting up its first city water system. He drilled a well 178 feet down behind the building and ran water up to a big tank, finally putting an end to the old, unreliable household wells. That changed daily life for a lot of people.

As decades rolled by, the building changed with the times. The hotel rooms upstairs turned into apartments in the 1920s, and the Johnson family moved in. When Louis Johnson died in 1946, his son Charles E. Johnson kept the place going—living upstairs himself and running a welding and marine supply shop on the first floor. Even as the commercial spaces emptied out, family members stayed on the second floor well into the late 1980s.

In 1987, the building landed on the National Register of Historic Places. That’s a nod to how much it means to Largo—one of the few old commercial spots left from before 1930, and a lasting reminder of how people like the Johnsons helped shape the city.

Right now, the building’s only partly in use, but it still stands as a symbol of Largo’s journey from a tiny railroad stop to a real city. Its story—full of ambition, hard work, and deep roots—keeps drawing people in. More than just bricks and mortar, the Louis Johnson Building is a piece of Largo’s soul, and a tribute to the vision and grit that built the place.
