In Pass-a-Grille, a Historic Plaque Is Also a Flood Strategy, With Limits

The Seahorse Restaurant has stood at 800 Pass-a-Grille Way since 1937, when it opened as a tavern. It became a drive-in restaurant the following year. Helene and Milton put several feet of water inside it in 2024. Owners Anayeri Gomez and Carlos Calvillo told the Tampa Bay Times the repair took five or six months of construction and seven to eight months of waiting on permits. They rebuilt the booths and decor from memories and old photographs so the room would look the way regulars remembered it.
The less visible step came first. In November 2024 the St. Pete Beach Historic Preservation Board granted the Seahorse local historic designation. The Times reported in January 2026 that the designation protects the building from potentially having to elevate, floodproof, or demolish after a future flood that damages more than half its value.
Plenty of Pass-a-Grille property owners made the same move after the storms. If you're shopping for an older cottage south of the Don CeSar, a historic plaque now tells you something about the flood rules. It protects some kinds of work and leaves other kinds exposed, and that split decides what you can do with the house later.
The City of St. Pete Beach's 2026 substantial improvement packet explains that the city applies the federal substantial improvement and substantial damage standard to buildings in Special Flood Hazard Areas. If repairs or improvements cost 50 percent or more of the building's value, the building has to meet current Florida Building Code and city flood rules. That can mean elevating it.
The value in that formula belongs to the structure alone. The city defines market value as the value of the buildings, "excluding the land." That figure comes from an independent appraiser or from the Pinellas County Property Appraiser's just value, adjusted to approximate market value. In Pass-a-Grille, much of a property's price sits in the land under it. The 50 percent line is measured against the cottage, so a renovation that sounds moderate can cross it.
Timing matters too. Before the storms, St. Pete Beach added up improvement costs over five years. Ordinance 2024-16, adopted December 10, 2024, cut that to one year. The count starts with the first permit issued after September 23, 2024. The same ordinance leaves certain code-compliant flood and wind mitigation, some energy-efficiency work, and specified mechanical replacements out of the running total. Every other permit a seller pulled counts toward the 50 percent line, which makes a seller's permit history a key due diligence item.
The city's definition carries an exception. Substantial improvement does not include "any alteration of a historic structure provided that the alteration will not preclude the structure's continued designation as a historic structure." That one sentence explains the rush to the register.
The city's register of locally designated historic properties starts on January 6, 1994. It lists 2506 Pass-a-Grille Way, the Hurley Realty building, as designation #1. Thirty years later, on September 5, 2024, 2507 Pass-a-Grille Way received #80.
Then the pace changed. Numbers #81 through #120 were issued between November 7, 2024 and May 1, 2025. The board kept going. It approved five more designations on June 5, 2025 and five more on October 2, 2025, all by 5–0 votes.
Many of those additions sit in the Casablanca, De Bazan, and Maritana streets near the Don CeSar rather than in Pass-a-Grille itself. A good number are on the historic grid, though:
Requests kept coming in 2026. The June 12 agenda included The Wharf at 2001 Pass-a-Grille Way. July 9 brought re-designation of the dwelling at 107 6th Avenue plus its accessory dwelling. August 6 listed 114 11th Avenue. The records we reviewed don't show final votes on those three. The city's published register also stops at May 2025, so it undercounts current designations.
Here is where the shortcut gets narrower. The city tightened the details in its Land Development Code through Ordinance 2024-18, adopted January 14, 2025, and amended the section again on January 27, 2026. Under Section 28.5 of the code, a designated building can be excluded from the substantial improvement definition only when three conditions hold:
Exterior work beyond ordinary maintenance that crosses the 50 percent threshold goes to the variance process in Section 28.16. In practice, the exemption fits the Seahorse approach of restoring what was there. A new second story, an enclosed porch, or a reworked facade sends the project back into the variance process.
The kind of listing matters as well. Pass-a-Grille has a National Register historic district, and plenty of houses there count as contributing structures. The city's 2026 substantial improvement packet addresses that status directly:
"Note that the City has higher standards for issuance of floodplain management variances and status as a contributing property to a nationally-designated historic district alone is not sufficient to pursue a variance."
The packet points owners to the historic preservation office if a structure is individually listed on the local registry or listed as a resource in a locally designated district. If that review finds the work won't jeopardize designation, the owner doesn't need to complete the substantial improvement packet. The Seahorse shows the difference. The Times reported that it was removed from the National Register district's contributing list in 2003 and still received local designation in 2024. For flood rules, the local register is the list that matters.
Local designation in St. Pete Beach is voluntary and requires the owner's written consent. Once a property is designated, the owner needs a Certificate of Appropriateness before permits for new construction, additions, moving the building, or demolition. Ordinary exterior maintenance that doesn't change materials, design, or appearance doesn't need one.
How permanent the designation is depends on whether the owner took a preservation incentive. Without one, the owner can end the designation any time after 12 months by giving the board at least 30 days' written notice. With one, the property stays designated for the life of its structures, and the restrictions transfer to a buyer for the rest of that period. For a buyer, the questions are whether the designation came with an incentive and whether the seller can document that.
Designation has not stopped every teardown. The register marks 202 and 204 Pass-a-Grille Way, circa 1917 and 1910, and 2311 Pass-a-Grille Way as demolished in 2024. On March 5, 2026, the board approved demolition, with no stay, of 103 1st Avenue, which had been designation #3. When a property has used an incentive, the code says the board can't deny a demolition request but can impose a stay of up to 90 days to explore alternatives.
Put together, a designated Pass-a-Grille cottage gives a buyer a clear way to restore the building after a flood and a slower, discretionary path for anything that changes how it looks. A buyer planning a faithful restoration can treat the plaque as an asset. A buyer planning to enlarge the house should expect the variance process. These are the questions to settle before the inspection period ends:
Does living inside the Pass-a-Grille National Register district exempt a house from the 50 percent rule? Not by itself. The city's 2026 packet says contributing status in a nationally designated district alone is not enough to pursue a floodplain variance. The exemption path runs through the local register.
Can a buyer remove a designation the seller applied for? If no preservation incentive was used, the code allows termination any time after 12 months from designation, with 30 days' written notice to the board. If an incentive was used, the designation stays for the life of the structures.
