A house built in 1925 has been standing for a hundred years. It went up when Calvin Coolidge was president, when St. Petersburg was in the middle of the Florida land boom, when the streets of Crescent Lake were new and the oaks that now shade them were young. A century is a long time for a wooden house in Florida to survive. The ones that make it this far, and make it this far in good condition, are worth slowing down to look at properly.
This is a piece about one of them. The home at 800 18th Avenue North sits in the Crescent Lake neighborhood of St. Petersburg, and it carries its 1925 origins in the way the best homes of that era do. It also happens to be for sale, and I am the listing agent, so I will be upfront about that here rather than pretending otherwise. But what I actually want to do in this piece is show you the house and the neighborhood the way I would show them to a friend, because the house deserves that and the neighborhood does too.
If you want the full picture of Crescent Lake as a place to live, I have written about it at length, and I will point you to that work along the way.
The House
The home was built in 1925 as a Colonial, wood frame construction, and it sits on a landscaped corner lot of just under a quarter acre at 18th Avenue North and the surrounding residential streets. The main residence runs three bedrooms and two baths, with the total heated area across the property at just over 3,000 square feet. It is the kind of home that the 1920s built well and that a century has tested.
Inside, the 1920s craftsmanship is the point. The living room is generous, a full thirty feet long, with a decorative wood-burning fireplace, built-in bookshelves, and exposed beamed ceilings, the architectural detail that came standard in that era and that new construction rarely attempts now. A downstairs sunroom sits off the main floor, the kind of light-filled room that ends up being where people actually spend their time, reading or working. The dining room has a built-in corner hutch, original to the home’s idea of itself as a place for gathering. The kitchen has been brought current, granite counters, breakfast bar seating, pantry storage, hardwood floors, and a full set of new stainless steel appliances, while keeping the character of the rooms around it.
Upstairs, the original pine hardwood floors are still in place, running through three bedrooms that fill with natural light. The primary bedroom has a walk-in closet and its own adjoining sunroom, a flexible space that a buyer could use as a home office, a nursery, a fitness room, or convert down the line into a third bath.
The home has also had the unglamorous but essential work done, the work that determines whether a hundred-year-old house is a pleasure or a project. The roof is new as of 2024. The HVAC systems were replaced in 2021. The water heater is new as of 2025. The interior has been freshly painted and the home professionally staged. A buyer is getting the 1925 character with the 2020s systems already handled, which is a genuinely different proposition from a historic home that still has all that capital expense ahead of it.
Outside, the lot is built for Florida living. A heated saltwater pool with travertine decking. A covered pergola. Defined outdoor entertaining areas. Mature landscaping with lighted palms and travertine walkways. The detached guest apartments overlook the pool, which gives the whole back of the property a private, enclosed, resort-like feel rather than the exposed-backyard feel of most lots.
The Two Guest Apartments
The feature that genuinely sets this property apart from almost anything else in Crescent Lake is the pair of accessory dwelling units. Above and below the detached garage are two private one-bedroom guest apartments, each with its own kitchen, its own private entrance, and a view over the pool area.
That is an exceptionally rare configuration for this neighborhood, and it opens up options that a standard single-family home cannot. Multigenerational living, with aging parents or adult children housed close but independent. Long-term guest space. A genuinely separate home office or studio, away from the main house. Or rental income, whether longer-term or, where permitted, shorter-term.
If income is part of what draws you to this property, here is the honest framing. The home is currently vacant and the units are not leased, so there is no established rent figure to quote. Based on current Crescent Lake area rents for comparable one-bedroom space, each unit could reasonably be estimated in the range of roughly $1,700 per month, but that is a market estimate of potential rather than a guaranteed or in-place number. The MLS listing sets a three-month minimum lease period with no association restrictions on leasing. Any buyer evaluating the income side should verify the current permitting status of both units, confirm what St. Petersburg’s rules allow for the rental use you have in mind, and run the operating numbers with real figures. The two apartments are a real and valuable asset. The responsible way to value them is with verified numbers, and I am glad to walk any serious buyer through exactly that.
Crescent Lake, the Neighborhood
The reason a 1925 home at this address is worth attention is not only the house. It is where the house is.
Crescent Lake is one of the most established and most loved historic neighborhoods in St. Petersburg. It sits in the central part of the city, a few blocks north of downtown, built out mostly between the 1910s and the 1940s, with brick streets on many blocks and a mature oak canopy overhead. The neighborhood is small enough to walk end to end in about twenty minutes, and it is anchored by Crescent Lake Park, a genuine fifty-acre lake ringed by a walking path, with baseball fields, tennis and pickleball courts, a playground, and a youth center. This particular home sits just steps from the park, and roughly a fifteen-minute walk from downtown St. Petersburg and the St. Pete Pier.
I have written about this neighborhood and this park more than almost any other place in Tampa Bay, because it rewards the attention. If you want to understand the park itself, its hundred-year-old water tower and its history as a New York Yankees spring training site, that is in my piece on Crescent Lake Park for the historichomestampabay.com Journal. If you want the broader argument about why a working neighborhood park like this one matters, that is in my LinkedIn article on what the park reveals about urban public ground. For the deeper architectural and historical treatment of the neighborhood as a whole, see the Crescent Lake neighborhood guide.
And if you are seriously weighing a move to Crescent Lake and want the honest, practical version of what living here actually involves, block by block, including what surprises new residents and what to know before you buy, that is in my buyer’s guide for MiddletonTampaBay.com.
The short version is this. People who live in Crescent Lake use the park almost every day. They walk it in the morning, run it in the evening, take their kids to the playground, play pickleball under the lights. The neighborhood functions at a human scale that most American cities have lost. A 1925 home here is not sitting in a generic subdivision. It is sitting inside one of the genuine neighborhoods of St. Petersburg, the kind people put down roots in and stay.
What It Is Like to Live Here
Daily life in Crescent Lake has a particular texture. The park is the center of it. So is the walkability, the ability to get to the lake, the coffee shop, the 4th Street corridor, and in many cases downtown St. Petersburg itself without needing the car for every errand.
The neighborhood is also well positioned for the practical realities of St. Petersburg in 2026. Crescent Lake sits on relatively elevated ground compared to the low-lying coastal parts of the city, and it did not see the widespread flooding that hit other St. Petersburg neighborhoods during Hurricane Helene in 2024. Flood zone status still varies parcel by parcel and any buyer should verify the specific designation for this address, but the neighborhood’s elevation profile is one of the reasons buyers who look elsewhere in historic St. Petersburg often end up focusing here.
For a buyer, the combination on offer at 800 18th Avenue North is genuinely specific. A century-old home with real character. Two accessory dwellings that open up options most properties cannot. And a location inside one of the most established and most walkable historic neighborhoods in the city.
