Two units go up for sale in Miramar Beach the same week. Same square footage, same view corridor, dues within fifty dollars of each other. One is in a resort tower built in the early 2000s. The other sits in a four-story building a few blocks down Scenic Gulf Drive that most buyers would describe as low-rise, almost boutique. On paper, the lower-dues unit looks like the better deal. It usually is not, and the reason has nothing to do with finishes or floor level.
Florida rewrote the rules on condominium reserves after the Surfside collapse in 2021, and the practical effect on the ground in Miramar Beach is that a building's monthly dues no longer tell you what they used to. A building that kept dues artificially low for a decade by skipping reserve contributions is now catching up, often through a special assessment that lands after you close rather than before. A building that raised dues years ago to fund its reserves honestly can look expensive on the surface while actually being the safer purchase. The dues sheet and the risk profile have quietly come apart, and almost nothing in a typical listing tells you which side of that split you are looking at.
Ask most buyers which Miramar Beach buildings fall under Florida's new structural reserve law and they will point to the tallest towers along Scenic Gulf Drive, places like Ariel Dunes I and II, the twin 24-story towers inside Seascape Resort that are the tallest residential buildings in Miramar Beach and South Walton. That instinct is understandable and it is also incomplete.
The law does not care how a building feels from the parking lot. Florida's Structural Integrity Reserve Study requirement, spelled out in Florida Statute 718.112(2)(g), applies to any residential condominium building three or more habitable stories in height, full stop. A four-story building on Scenic Gulf Drive, the kind of property people describe as an old Florida throwback with a small pool and a shared grill, clears that threshold as easily as a high-rise does. The narrow carve-out in the statute is for four-family dwellings with three or fewer habitable stories, essentially small residential buildings, not the resort-style condo buildings that make up most of Miramar Beach's inventory. A modest four-story association is in the same regulatory bucket as a 24-story tower. Height above three stories is the trigger. Everything past that line is treated the same under the law.
Buyers often conflate two separate requirements, and the difference changes what you should actually ask for.
| Requirement | What it measures | What sets the deadline |
|---|---|---|
| Structural Integrity Reserve Study (SIRS) | Whether reserves are fully funded for eight structural components: roof, load-bearing structure, fire protection, plumbing, electrical, waterproofing and exterior paint, windows and doors, and any other item over the statutory threshold | Building height (three or more habitable stories), not age. Existing associations had to complete their first SIRS by December 31, 2025, and reserve funding under that study had to begin January 1, 2026. |
| Milestone inspection | The physical condition of the structure itself, checked by a licensed engineer or architect | Building age. The statewide baseline is an initial inspection at 30 years, with some jurisdictions applying a 25-year trigger for buildings near the coast. Inspections repeat every 10 years after that. |
The distinction matters because a building can be well past its SIRS deadline while still years away from needing its first milestone inspection, or the reverse. A 2007-built resort tower and a four-story building from the 1990s both need a current SIRS on file today. Only the older one is anywhere near its milestone inspection window.
Ariel Dunes I and II were completed in 2007 with 462 units across the two towers. That puts them nowhere close to a milestone inspection, whether the county applies the 25-year coastal trigger or the 30-year statewide baseline. What it does not do is exempt them from the SIRS reserve mandate. Height put both towers in scope the moment the law took effect, regardless of how new they feel compared to their neighbors. A buyer touring Ariel Dunes should still ask for the current SIRS and the reserve funding percentage, the same as they would at a much older building.
Majestic Sun, the twin 12-story tower inside Seascape Resort, was built in 2001. Depending on whether Walton County's building official applies the 25-year coastal standard or the statewide 30-year baseline, Majestic Sun is either at the edge of its first milestone inspection window right now or has several years of runway left. That is not a detail a listing sheet will resolve for you. It is a two-minute call to the county building department, and it is worth making before you write an offer rather than after.
Buildings like Edgewater and Mainsail, both on the Scenic Gulf Drive stretch of Miramar Beach, raise the same set of questions regardless of exact completion year: has the SIRS been done, is the reserve fund tracking the schedule that study recommends, and has the association ever borrowed against future assessments to cover a shortfall. The four-story buildings on that same stretch, properties like Ciboney and The Crescent, deserve the identical checklist. Their lower height does not lower the bar.
Florida law already requires sellers and associations to hand over a specific set of documents to a prospective buyer, and the list under Florida Statute 718.503 is your leverage here. Before you go under contract on any Miramar Beach condo, ask for:
A building can look financially healthy in a monthly budget while quietly carrying debt service on a reserve loan that will show up in your dues later. That loan is legal under the current law, and it is also exactly the kind of liability a buyer needs to see coming rather than discover in year two.
Miramar Beach's condo market in early 2026 has been a market of two speeds. Listings across the ZIP code were spending somewhere in the range of 100 to 112 days on market, depending on the source, with list prices softening compared to the prior year. That average hides a real split. Buildings that came to market with a completed SIRS, a documented reserve funding history, and no surprise assessment pending have continued to close close to asking. Buildings where a pending or rumored assessment shows up in board minutes have sat, sometimes for months longer, while buyers wait for clarity or negotiate the assessment into the price.
That split is the practical version of everything above. The building's age and story count set which laws apply. The building's actual compliance with those laws, not its dues number, sets how it performs on the market and what it will cost you to own.
Does a four-story Miramar Beach condo really need a milestone inspection? Yes, once it reaches the age threshold. Florida's milestone inspection law applies to any residential condominium building three or more habitable stories, and a four-story building clears that bar the same as a high-rise. The only real exemption in the statute is for small four-family dwellings with three or fewer stories, which does not describe the resort-style four-story buildings common in Miramar Beach.
What if I'm under contract and the building hasn't completed its SIRS yet? Ask why. The statewide deadline for existing associations was December 31, 2025, so a building that still has not filed one is behind schedule, and that delay is worth understanding before you close. Request a firm timeline in writing and consider a contingency tied to receiving the completed study.
Can an association still skip reserve funding for anything? Only for non-structural items outside the eight SIRS categories. For budgets adopted after December 31, 2024, the structural reserves identified in the SIRS can no longer be waived or reduced by owner vote. Other capital items, like a clubhouse renovation or a landscaping fund, can still be waived if the membership chooses.
Buying a condo along Scenic Gulf Drive or inside a Seascape Resort tower is still a strong move for the right buyer, but the due diligence has changed since 2022 in ways a lot of listing sheets have not caught up to. If you want a second set of eyes on a building's reserve position before you write an offer, or you are trying to figure out whether a low dues number is a feature or a warning sign, Enslen Coastal Group can walk the documents with you and put the numbers in context before you decide.
