What it's actually like to live here
The pitch is boutique living on the bayfront. With only 117 units across 28 floors, the building stays quiet, and the amenity deck still covers the essentials: an infinity-edged heated pool and whirlpool, a poolside barbecue and bar, a fitness center, a spa, and a cardio room. A climate-controlled wine cellar and a billiards and sports lounge round it out, with 24-hour concierge and valet.
At 117 units, Onyx trades the crowds of the mega-towers for a quieter bayfront building with a full amenity deck.
Floor plans and what units cost
Residences run from one to three bedrooms plus penthouses, roughly 942 to 1,508 square feet, so there is a real spread between the smaller lines and the larger bay-facing units. As of the latest MLS pull there are 6 active units asking $620,000 – $870,000. The middle of that sat near $809,500, or about $615 a square foot (SEFMLS, live).
Monthly maintenance runs around $2,030 at the median across active units, which reflects the staffed services and amenity base. Always confirm the exact figure and what it includes for the specific unit you’re considering.
One to three bedrooms plus penthouses, roughly 942 to 1,508 square feet, so the line and the view drive the number.
The Edgewater location
The address is 665 NE 25th Street, in the heart of the Edgewater bayfront. The Design District’s luxury retail and Midtown’s shopping are minutes north, Wynwood is a short drive inland, and Downtown, the Adrienne Arsht Center, and the causeways to South Beach are all close. The map, walk-time list, and nearby-buildings sections above show exactly what is within reach.

Buying and owning at Onyx on the Bay
Onyx on the Bay reads differently from its neighbors because it is small. With 117 units it skips the crowding and elevator waits of the mega-towers, and the no-weight-limit pet policy pulls buyers who get shut out of stricter buildings. There are currently 6 active units on the market (SEFMLS, live), so there is real, current inventory to price against. It sits in the heart of the Edgewater bayfront, so the location is identical to the bigger towers without the density.
Before you commit, confirm three things in writing: the HOA dues and what they include, the pet bylaws, and the minimum lease term. The pet policy here is a draw, two pets with no weight limit, but policies change, so get the current rule in writing if that is part of why you are buying.
