Who is behind it, and what is there now
A name change the town wrote down, a vacant two acres, and eight slips approved this month
Start with identity, because this series has just had to kill a page for want of exactly what this project has. The town's own planning and zoning approval status sheet carries the entry verbatim as Porto Longboat Key Residences, with the name changed to Evolve, at this street address, described as an eight unit condominium project with an eight slip dock. That is a municipal government record naming both names against the address.
The state's version of the same project is less reliable. The state condominium file misspells the developer's name, transposing letters in the word Longboat. Two independent primary records, the county roll and the state corporate register, agree on the correct name and on a Sarasota mailing address. We checked rather than assumed, because the same assumption was a false positive on a Siesta Key street name in the previous batch.
One trap that will catch a casual researcher. The project's own marketing carries a Main Street address in Sarasota. That is the developer's sales office, not the building. The building is on Gulf of Mexico Drive in a different county. And a recent trade article about a Longboat Key building's colourful fifty year history is about a different property on the north end entirely. It is not this site.
On the county question, the state is right and our instinct was wrong. This is Manatee County, not Sarasota. The parcel returns a Manatee census identifier and a Manatee tax district from the county's own service, and it does not appear in the Sarasota roll at all. The key straddles the line; this address is north of it. Your taxes, schools, evacuation orders and deeds are all Manatee, while the town is the permitting authority.
The site itself is a clean sheet and the roll says so in four ways at once. Just over two acres, assembled from several parent parcels into a single folio created in October 2021, carried as vacant commercial with improvements, with zero living units and no year built. The improvement value is about $10,583 against land of about $1.89 million. That residual is paving and seawall remnants, not a building. Whatever stood here is already gone.
We can tell you what kind of thing it was without inventing a name. The parcel is classified commercial and the project needed its land use changed before homes could be approved on it, so a commercial property occupied this ground. No record we could reach names the business, and one promising article turned out to be about a different building. We leave it there rather than guess.
The entitlement path is the substantive story, and it is heavier than a routine approval. Four separate approvals landed in January 2023: a comprehensive plan amendment, a rezoning, a special exception and a site development plan. The plan amendment is the heavy instrument, because the town had to change the property's future land use designation from commercial before it could be rezoned at all. On a built-out barrier island that is not a formality.
We looked hard for a density story and did not find one, so we will not write one. There is no primary record of any tourism unit transfer, density unit transfer or relief from a density cap. The town's status sheet does not mention one. What the record supports is a land use change from commercial to residential, and nothing more.
The most current fact available is the marina, approved this month. The Town Commission approved a private dredge order by unanimous vote in September 2026: roughly 1,335 cubic yards of excavation for an eight slip basin, a new seawall encircling it, the basin held at least twelve feet clear of the property to the east, slips restricted to residents and guests, no commercial use and no boat ramp. Eight homes and eight slips is a one to one ratio, and the conditions are worth reading in the order rather than in a brochure.
Two fields on the official record are wrong here, and you should know which. The construction permit is classified as detached one and two family residential for what is an eight unit condominium, and the waterfront flag reads no on a bayfront parcel with an approved boat basin. Both are administrative artefacts. This series has been caught by roll fields before, including one that named a bank as the owner of nine units it had never been deeded.
Take these four to the sales gallery: the construction schedule now that the permit is open and the dredge order is approved; the dredge order itself and what the resident-only slip conditions mean for renting or selling a slip; when the declaration of condominium is expected to record; and what a reservation commits you to and how your deposit is held before that happens.
What this will actually cost
The bay side is taxed at a lower rate than the gulf side, and here is by how much
This town does something most buyers have never heard of, and it is directly relevant to which side of the road you buy on. Longboat Key levies separate bayside and gulfside rates. The bayside total for 2025 is 14.8362 mills. The gulfside total is 15.2534. This building is on the bay side, so it pays 0.4172 mills less. That is not a rounding difference across twelve levy lines.
The gap has a single cause and it is a fair one. The bayside district levy is 0.1391 mills against the gulfside district's 0.5563, and the gulfside levy funds beach renourishment. The properties that have the beach in front of them pay for keeping it there. On a Gulf front address that is money well spent. On this one it is money not spent.
Against the rest of the county the town sits comfortably in the middle. The mainland cities are far dearer, at roughly 19.17 and 18.41 mills, while the unincorporated county baseline is 13.31. Longboat Key's bayside rate is about 1.5 mills above that baseline and well over three mills below the dearest city. The town's own municipal component is only 1.96 mills of the total; the county and the school district carry most of the rest.
One thing this series has to correct as it crosses the county line. Sarasota County has no ad valorem community development districts at all, and we have said so repeatedly on pages a few miles south. That framing does not transfer. Manatee County has exactly one, inland on the mainland, nowhere near this key. This parcel carries no district assessment and no district name in its taxing authority string, so the answer here is still none, for a different reason.
On value, the two roll layers do something they almost never do. They agree exactly. The certified layer and the working layer both carry this parcel at $1,900,560, and it is real agreement rather than staleness: one was refreshed in June 2026 and the other in September 2026. We still print both rather than averaging, because on the last three projects in this series they disagreed, in one case by enough that a reader consulting only the certified layer would conclude the building did not exist.
Almost all of that value is dirt, which is what you would expect and worth confirming. The land component is about $1.89 million and the improvement component about $10,583, so roughly 99 per cent of the parcel's value is land. The assessment method on the roll is cost, and assessed equals taxable across every authority, because there is nothing built and nobody homesteaded.
One number on this parcel must never be read as a price. The last conveyance on the roll is a nominal corrective instrument recorded in May 2025 at ten dollars. That is a title cleanup or an entity level transfer, not a market sale, and quoting it as a purchase price would be badly wrong. Earlier trades reported in the press are secondary and we have not verified them against deeds, because this county's clerk publishes no route we could read.
The practical version: the rate is knowable today, the bay side genuinely costs less than the gulf side and you can check by how much, and there is no community development district on this parcel. Once the building exists and units are folioed, each unit's own assessment will drive the bill, and non ad valorem assessments are additional to every figure above.
The compliance clock
What a buyer can and cannot see before the declaration records
Almost everything Florida gives a condominium buyer attaches to a condominium that legally exists. This one does not yet, and the honest version of that is a list.
Here is what you cannot see, because it has not been created. No recorded declaration, so no unit boundaries, no percentage interests and no restrictions to read. No budget, no reserve schedule and no insurance position, because there is no association to hold them. No recorded sale to price against, because no unit has ever been conveyed. At a finished building all of those exist and can be demanded. Here they do not.
On the state's recorded condominium roll, the absence means something specific here. The state only requires registration above seven units, and at eight this project clears that comfortably. So its absence from the recorded roll most likely means the declaration genuinely has not recorded yet, rather than being a reporting artefact. That fits a building permitted in August 2026 and not yet under way.
What you can see is the town's file, and this town is unusually open about it. Its planning approval status sheet is published as a document anyone can read, and it is the record that identifies this project by both of its names. That is more than the unincorporated county a few miles south offers, where the building, fire, public works and enforcement modules are all behind a login. The town's own permit detail is thinner, but the approvals themselves are public.
On the structural obligations, the clocks have not started and one question is genuinely open. A structural integrity reserve study falls due within ten years of a condominium's creation, and this condominium has not been created. The milestone inspection regime turns on habitable storeys rather than units, and whether this building has two habitable levels or three depends on how its rooftop level is counted. No record we retrieved answers that, so we do not tell you the answer.
We can tell you why the question arises at all, because it is a design consequence. Natural ground here is about two feet and the base flood elevation is eight, so the lowest habitable floor has to sit roughly six feet above existing grade. That is why a building described as three storeys has an amenity and garage level at grade. Three storey over parking buildings on barrier islands are exactly where this test gets argued.
Turnover is the same story one step further out. Control of the association passes from the developer to the owners on thresholds tied to how many units have been conveyed, and none have. The developer will control the association through construction, the first budget and the first reserve decisions. At eight owners, those first decisions are spread very thinly, which cuts both ways.
What to ask for in writing at this stage: the expected recording date for the declaration; the draft declaration, budget and reserve schedule as soon as they exist; how many habitable storeys the building is being permitted as; what a reservation commits you to and how your deposit is held; and the expected turnover date.
The area
One flood zone on this parcel, three velocity zones across the road, and a parcel that flooded in 2024
This is the sharpest single finding on the page, and it turns on one line in a surveyor's description.
We expected a barrier island mess and did not get one. A whole parcel query against the federal flood layer returns exactly one zone across the entire property, a coastal floodplain designation with a base flood elevation of eight feet. No velocity zone, no mapped wave action line, no primary frontal dune, and no zone break anywhere on the parcel. On the last barrier island parcel in this series the same query returned five zones.
We proved that negative rather than reporting it. Re-running the identical layers against a 300 metre buffer returned the full barrier island picture immediately: velocity zones at twelve, thirteen and fourteen feet, plus wave action lines, all of it across the road on the Gulf side. The layers work here. They simply return nothing extra on this parcel.
The reason is structural, permanent, and printed in the legal description. This parcel begins at the easterly right of way line of Gulf of Mexico Drive. It is on the bay side. The road itself separates the property from the Gulf front velocity zones opposite. That is a genuine, checkable difference between this address and a Gulf front one, and it will still be true in thirty years.
The storm side is where this site is exposed, and the two answers are not in conflict. This is evacuation level A, the first zone ordered to leave, and the parcel falls inside the category one surge envelope, which means it is inside all five. Level A is called in the weakest qualifying storm. Being out of the velocity zone is an insurance and construction fact. Being in level A is a life safety fact. They measure different things.
And this is not a model. It happened. The county's own observed inundation mapping for the September 2024 storm returns a positive hit on this parcel. The site was under water in that event. Natural ground measured about two feet against a base flood of eight, which is the same six foot gap that shapes the building's ground level.
The postcode claim record tells the same story in dollars, and it is one month rather than a pattern. This postcode has recorded about 2,918 federal flood insurance claims and roughly $206.5 million paid across the life of the programme. The single month of September 2024 accounts for 87.8 per cent of every dollar ever paid, and calendar 2024 as a whole accounts for 89.3 per cent. Those two figures measure different things and we keep them separate deliberately.
The gap between them is the second storm, and the history before both is small. October 2024 accounts for about 1.5 per cent, which is nearly the whole difference between the month figure and the year figure. Before 2023, this postcode's entire claim history across four decades totals under $12 million. That is a single event risk profile rather than a chronic one, and the parcel was inside that event's footprint.
On schools we are deliberately going to disappoint you, and we would rather do that than be wrong. This county publishes no queryable school attendance boundaries, unlike its parcel, evacuation and flood layers, and the district was redrawing its maps as recently as late 2025. So we name no schools. Every portal listing for this address will name three anyway. Ask the district.
What you need to know
Buying pre-construction with someone on your side
Representation costs you nothing and the timing is the catch: in a developer sales gallery your agent generally has to be with you or named at your very first contact for the registration to stand. Sort it out before you call.
The case for it here is that eight units is a very small denominator. Every decision the association will ever make, every reserve line, every insurance renewal and every seawall and basin maintenance bill will be shared between eight owners. On a bayfront parcel with a dredged basin and a new seawall, that is not an abstract point. Ask what the developer projects those costs to be, and on what basis.
Know what the statute gives you once documents exist. On a developer sale you are entitled to the prospectus and the condominium documents, and you have a rescission right measured in days from the later of signing or delivery of those documents. At this stage that window has not opened, because the declaration has not recorded. Ask how a reservation converts to a contract, and what happens to your money between.
On deposits the protection is narrower than most buyers assume. The first ten per cent is held in escrow. Above ten per cent the statute permits the developer to use the money for construction once work has begun, and here the permit is open but work has not visibly started. We did not search Florida regulatory enforcement records or civil dockets for any builder, developer, contractor or land-holding entity, so read the absence of any such note as unchecked, not clean. Get an independent inspection before closing whenever that comes, use the warranty window, and read the limited warranty before you sign.

Questions and answers
Evolve FAQ
Is Evolve the same project as Porto Longboat Key Residences?
Yes, and we can prove it from a government record rather than from marketing. The Town of Longboat Key's own planning and zoning development approval status sheet carries the entry verbatim as Porto Longboat Key Residences with the name changed to Evolve, at this street address, described as an eight unit condominium project with an eight slip dock. That is the strongest identification in this whole series: a municipal planning record naming both the old name and the new one against the address. We print both names because a buyer who heard about this project a year ago will be searching the old one. One trap worth flagging: the project's marketing materials carry a Main Street address in Sarasota. That is the developer's sales office. The building is on Gulf of Mexico Drive.
Which county is it in?
Manatee. That surprises people, because Longboat Key reads as Sarasota in almost every way that matters socially, and the key genuinely does straddle the county line. We tested it rather than assuming: the county parcel record returns a Manatee census identifier, a Longboat Key jurisdiction, and a Manatee tax district, and the parcel does not appear in the Sarasota roll at all. The practical consequences are real. Your property tax bill, your school district, your evacuation notices, your emergency services and your recorded deeds are all Manatee County, while the town itself is the zoning and permitting authority. Anyone researching this address in Sarasota County records will find nothing, and will probably conclude the wrong thing from it.
Is it built, and when will it be?
Not built and not visibly started. The construction permit issued in August 2026 at an eight million dollar declared construction value and is open, corroborated independently by local reporting on the September 2026 dredge approval, which noted the project should get underway shortly. But the county roll still carries this parcel as legally vacant: zero living units, no year built, and an improvement value of about $10,583 against land of about $1.89 million, which is a residual for paving and seawall remnants rather than a building. On timing, we will not give you a false precision. The entitlements were granted in January 2023 and the permit issued about 43 months later, which is a slow entitlement to permit interval, but it is not the same measurement as the application to occupancy figures this series tracks elsewhere and we do not mix them. What we can say is that comparable projects in this corpus have run three to six and a half years from application to occupancy, and this one has only just reached the start of construction.
What about the boat slips?
They are real, they are municipally approved, and they are restricted. The Town Commission approved a private dredge order by unanimous vote in September 2026 for the project's eight slip private boat basin. The approved work is roughly 1,335 cubic yards of excavation with a new seawall encircling the basin, and the basin must sit at least twelve feet clear of the adjoining property to the east. The conditions are the part worth reading: the slips are restricted to residents and their guests, there is to be no commercial use, and there is to be no boat ramp. Eight residences and eight slips is a one to one ratio, which is unusual, but the approval is an order with conditions attached rather than an open permission, and a buyer should read the order itself rather than a brochure line about a private marina.
What is the flood and storm position?
Better than a barrier island address usually is on the flood maps, and worse than most buyers expect on storms. We queried the federal flood layer against the whole parcel polygon rather than a point, and it returns exactly one zone across the entire property, a coastal floodplain designation with a base flood elevation of eight feet. There is no velocity zone anywhere on the parcel, no mapped wave action line, and no primary frontal dune. To prove that was a real negative rather than a failed query we re-ran the same layers against a 300 metre buffer and got the full barrier island picture immediately: velocity zones at twelve, thirteen and fourteen feet, all across the road on the Gulf side. The parcel's own legal description begins at the easterly right of way line of the road, and that one line of surveying is why. The storm side is harsher. This is evacuation level A, the first zone ordered out, inside the category one surge envelope, and the county's own observed inundation mapping records this parcel as flooded during the September 2024 storm. Natural ground here is about two feet against a base flood of eight.
What should I be most careful about here?
Four things. First, nothing about the condominium exists yet as a legal object: no recorded declaration, no budget, no reserve schedule, no association and no recorded sale. Second, at eight units this project clears the state's registration threshold comfortably, so its absence from the recorded condominium roll most likely means the declaration genuinely has not been recorded yet, rather than being a reporting lag. Third, two fields on the county roll are demonstrably unreliable here: the permit is classified as detached one and two family residential for an eight unit condominium, and the waterfront flag reads no on a bayfront parcel with an approved boat basin. Fourth, we deliberately do not name your schools. This county publishes no queryable attendance boundaries and was redrawing its maps as recently as late 2025, so every school assignment you will see on a listing portal for this address is unverified.
