Two neighbouring towers in Key Biscayne can charge very different dues without either being the better building: what changes is what the dues include and what you pay separately. The useful question is not how much, but what it covers and who set it.
Association dues are the one ownership cost a third party sets for you and can raise without asking you. They come out of an annual budget the association approves, and that budget tells you whether the building is paying for its upkeep on time or postponing it. Low dues with empty reserves are not a saving: they are a special assessment that has not arrived yet, and whoever owns the unit when it is approved inherits it.
Key Biscayne moves through a different channel because the village keeps its own permit counter and because everything that reaches the island crosses a single bridge. For a buyer abroad that is not scenery, it is logistics. The contractor quoting a renovation prices in travel and the delivery window in which material can be unloaded; the appraiser and the inspector your lender sends depend on that same bridge; and scheduled work can stop because of a closure nobody told the buyer about. On top of that, the county does not grant the approval: height, setback, landscaping and dune protection rules are set by the village, and when the parcel touches the shore a state authority enters as well, so a wall, a dock or a pool may require more than one file. Ask your insurance broker how the carrier reads the exposure of that specific parcel and what it requires before issuing; ask your closing attorney whether dune restrictions or easements are recorded on title; ask the village which work is approved at the counter and which goes before a board. It also pays to learn who manages the building or the association, because on a small island the manager is the person who actually answers.
What is specific to Key Biscayne
A barrier island with its own village government, reached only by the Rickenbacker Causeway, with large parks at both ends. Oceanfront towers, low-rise buildings and a core of single-family homes inland. A single tolled road in; there is no rail and no alternative if the causeway closes.
- what the single road implies: evacuation, rush hour and closures for works or events
- the parcel's coastal exposure and what that means for insurance
- the village's own rules, which are not the county's
What to verify, step by step
- Ask for the association's current annual budget and the list of what the dues actually pay for: water, cable, the building's insurance, security, valet, gym.
- Ask separately for the list of what the dues do NOT cover, because parking, storage and the unit's electricity usually live there.
- Ask for the minutes of the meeting that approved the current dues, not last year's, and compare the two to see the trend.
- Ask in writing whether a special assessment is approved, under study or already being collected in instalments, and whether an unpaid balance travels with the unit.
- Ask how many units are delinquent, because the dues of those who do not pay end up covered by those who do.
- Check with the state condominium division what the association is required to hand you before closing.
Mistakes that cost money
- Comparing two buildings' dues without comparing what each one includes: high dues that cover water and insurance can cost less than low dues.
- Taking the figure in the listing at face value. The current dues are in the approved budget, not in the unit's brochure.
- Forgetting that the association can raise the dues after closing without the buyer having a vote in that decision.
Frequently asked questions
- Can the association raise the dues after I buy?
- Yes, and it is normal: dues are approved every year in the budget. Ask for the last several budgets to see how they have moved.
- If the previous owner left dues unpaid, do I pay them?
- That is precisely the question to ask in writing before closing, and to ask a Florida-licensed attorney, because the answer depends on the document the association issues and on how the closing is structured.
- What is an association estoppel?
- The certificate in which the association states what the unit owes and what charges are outstanding. It is always requested before closing, never after.
