Chateau Beach Residences, Sunny Isles Beach: What Buyers Should Check

Chateau Beach Residences is a 33-story curved glass tower at 17475 Collins Avenue in Sunny Isles Beach, completed in 2016. It is the boutique of the Sunny Isles oceanfront: just 81 residences, all of them large — two to four bedrooms from 1,465 to 9,051 square feet, with a median of 2,703 square feet — and there is no small entry point here at all. The tower was designed by Kobi Karp for Chateau Group, the Grosskopf family's firm, as its first Florida project, and its long curve follows the shape of the dunes. To the south sits Samson Oceanfront Park, which means the light and the views on that side can never be built out. One full floor — about 22,000 square feet — is given over to amenities run at hotel register. This is a top-tier building with top-tier carrying costs, and the monthly bill is the first thing a buyer should get straight.

Amenities and day-to-day living

The amenity program fills a full floor of about 22,000 square feet: an infinity-edge pool, a ballroom, a wine lounge with private lockers, a cigar bar with a walk-in humidor, a residents' Moon bar with ocean views, his-and-hers spa facilities, a fitness center, sauna and spa/hot tub, a business center, a clubhouse, and a community kitchen. Residences are reached by private elevators (semi-private for the two-bedroom lines), with 10-foot ceilings, walls of glass, and glass-edged balconies. At the top sit a Collection Residence, a two-story Sky Villa, and a two-story Penthouse Villa. Parking allocation varies by residence — the penthouse listing carries four spaces — so confirm what comes with the unit you are considering. The building trades more often than most at this price point: about one home in 19 changes hands in a typical year, so comparables usually exist.

What to check before you buy

• Monthly cost, honestly. No verified building-wide dues figure was found for this building, and at this size the bill is large. CondoBlackBook puts the average association fee at about $1.96 per sq ft per month; a current penthouse listing shows $17,545 a month for the 9,051 sq ft penthouse — about $1.94 per sq ft — which is consistent with that average. Get the exact figure for the residence you are considering, including what the dues cover, and use the monthly-cost worksheet in the Buyer's Guide, not just the mortgage payment.
• Milestone inspection. Florida milestone inspection rules generally apply at 30 years, or 25 years within 3 miles of the coast. This is an oceanfront building completed in 2016, so its first milestone inspection falls in the 2040s — around 2041 on the 25-year coastal rule — but confirm the building's milestone and SIRS status with the association rather than relying on a listing.
• 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 this building's position with its association.
• Owner-occupancy ratio. Lenders check this ratio before approving a mortgage, so confirm the current figure with the association — a building heavy on rentals can block financing. No verified owner-occupancy figure was found for Chateau Beach.
• Rentals. Rentals are rare here and sit at the top of the market — two residences were listed for rent in November 2026, one from $24,000 a month. No verified minimum lease term or rental cap was found in public sources; confirm the leasing rules with the association before you buy.
• Pets. No verified pet policy was found stated in public sources for this building. Confirm the current rules with the association before you buy if a pet is part of the plan.

Who this building suits

Chateau Beach Residences suits a buyer who wants a large oceanfront home in Sunny Isles Beach and is buying at today's prices rather than inheriting a 2015 basis — nothing here is small, the four-bedroom count is high for a building of 81 homes, and it trades often enough that comparables exist. It is a poor fit for a buyer who wants a modest entry point: the county assesses the least valuable home in the building above $1.25 million, and the monthly carrying cost runs with the size of the home. It is also a poor fit for anyone hoping to repeat the 2015 launch experience — of the original buyers who have since resold, nearly 43% sold at a loss.
