Oceania, Sunny Isles Beach: What Buyers Should Check

Oceania is Sunny Isles Beach's original resort community: five towers built through the 1990s on a private island at the south end of the beach, between 164th and 165th Streets. Three towers (I, II, and III) stand directly on the ocean; two towers (IV and V) sit across Collins Avenue on Oceania Island, on the Intracoastal, with a private marina. All five share the Oceania Beach Club — restaurant, spa, tennis, and private beach — and a gated, resort-style campus built on the grounds of the old Castaways motel, demolished in 1984. It is the largest and oldest oceanfront community in the sweep, and the entry point to Sunny Isles luxury: the smallest residences and the lowest dues of any oceanfront complex on Collins Avenue.

Amenities and day-to-day living

The shared Oceania Beach Club is the center of the community: an oceanfront restaurant and café, a 30,000-square-foot spa and fitness center, a full-service spa and beauty salon with sauna and steam rooms, lighted tennis courts, racquetball and squash courts, a basketball court, a putting green, and a private beach with cabana service and beach attendants. The Oceania marina across Collins on the Intracoastal offers boat slips sold or rented to residents when available. Each tower also has its own amenities: Tower IV has its own fitness center, tennis courts, community room, business center, and pool deck (described in listings as undergoing a complete renovation in 2026); Tower V has a lap pool and hot tub, fitness room with sauna, children's play area, social rooms, a dog-walk area, tennis courts, concierge, valet, and assigned garage parking. Services across the complex include 24-hour security and valet, concierge, and beach service. Parking is valet with assigned garage spaces — most residences have two, and larger homes have more; Tower V includes townhouses with private garages and elevators. Pets are generally allowed with restrictions across the towers — size, breed, and count limits are common, and Tower V listings note a $350 pet deposit — confirm the current pet rules with the association before you buy.

What to check before you buy

• Monthly cost, honestly. Dues vary by tower and unit. Median association fees across current MLS listings are about $1,642 a month at Tower III (~$0.97 per sq ft), about $1,667 a month at Tower IV (~$0.81 per sq ft), and about $1,723 a month at Tower V (~$0.75 per sq ft), as of November 2026. Homes.com ranges run wider — roughly $100–$4,116 a month depending on tower and unit — so get the exact figure for the residence you are considering, and use the monthly-cost worksheet in the Buyer's Guide, not just the mortgage payment. These figures exclude any special assessment.
• Owner-occupancy ratio. Lenders check this ratio before approving a mortgage, so confirm the current figure for the tower you are buying into with the association — a building heavy on rentals can block financing. No verified owner-occupancy figure was found for any Oceania tower.
• Reserves and assessments. Ask what reserves are funded, what assessments are planned or already approved, and where the building stands on its Structural Integrity Reserve Study (SIRS). Under Florida's SIRS rules, reserves for SIRS items are no longer waivable — but confirm each tower's position with its association. Note that Oceania V has its own association, separate from the other four towers.
• Milestone inspection — this one matters now. Florida milestone inspection rules generally apply at 30 years, or 25 years within 3 miles of the coast. Towers I, II, and III were completed in 1990–1991, so their first milestone inspections are already due or past under either rule — ask the association for the completed reports and any assessments that followed them. Tower IV (1995) is in the same position. Tower V (2002) is the exception: its first inspection falls around 2027 on the 25-year coastal rule, or 2032 on the 30-year rule. For a 1990s tower, the milestone report is not a future event — it is a document that should already exist.
• Rentals — the rules differ by tower. Tower III allows annual leases only (12-month minimum). Towers IV and V allow up to two leases a year with a 6-month minimum, and no nightly or seasonal rentals. Leasing rules for Towers I and II were not verified per tower. Rental rules are set by each condominium's declaration and can be amended by the board, so verify the current rules for the specific tower with the association before you buy for rental income.

Who this building suits

Oceania suits a buyer who wants the resort-community lifestyle — beach club, marina, tennis, restaurants, gated island — at the lowest price and dues of any oceanfront complex in Sunny Isles Beach, and who is comfortable with a 1990s building rather than new construction. Towers I, II, and III suit a buyer who wants to be directly on the sand; Towers IV and V suit a boater, or a buyer who wants Intracoastal and skyline views with the marina at the door. It is a poor fit for a buyer who wants new construction, the newest finishes, or a small, quiet boutique tower — and a poor fit for anyone who will not ask for the milestone reports on a 30-plus-year-old building before signing.
