Onix Delray Beach Condos
Updated October 29, 2026
Onix Delray Beach (also written Onix) is a 26-residence boutique condominium at 318 Southeast 5th Avenue, three blocks from Atlantic Avenue. Pricing starts at $1.549 million for two- and three-bedroom residences of 1,400 to 2,000 square feet, which puts it roughly in the $775 to $1,100 per square foot range depending on plan. Vertical construction is underway.
What Onix costs per square foot, and why that number matters
Price ranges are useless for comparison. Price per square foot is how you actually decide between buildings. Here is the arithmetic, shown openly.
| Scenario | Price | Interior | Approx. PSF |
|---|---|---|---|
| Largest residence at entry pricing | $1,549,000 | 2,000 sq ft | ~$775 |
| Largest residence at top published price | $2,200,000 | 2,000 sq ft | ~$1,100 |
| Smallest residence at entry pricing | $1,549,000 | 1,400 sq ft | ~$1,106 |
These are computed from published price and size ranges, not from a per-plan price list, because the developer does not publish one. The practical takeaway is the band: Onix trades somewhere around $800 to $1,100 per square foot.
Now the comparison that matters. Glass House in downtown Boca Raton starts at roughly $1,210 per square foot on the same computation. Onix is meaningfully cheaper per foot than the new downtown Boca towers, and it is three blocks from Atlantic Avenue rather than three blocks from Mizner Park. If you have been told Delray and Boca are priced the same on new construction, they are not.
A discrepancy worth knowing about. Published completion dates for this building do not agree. Developer-supplied data currently indicates 2026. Other third-party listing sites variously show 2025, 2027 to 2028, and 2028. Vertical construction began relatively recently, which makes the earlier dates look optimistic.
I am not going to guess on your behalf. If your timeline matters - and on pre-construction it always does - ask me and I will confirm the current delivery estimate directly with the sales team rather than repeating a number off a web page.

Who this building actually suits
Twenty-six residences with ground-floor retail, three blocks off Atlantic. That is a specific proposition and it is not for everyone.
- It works if you want to walk to dinner on Atlantic without living on top of it, and you want a building small enough that you will know your neighbors.
- It works if you are coming from the Northeast and want Delray's scale rather than Boca's. Delray is a walking town in a way Boca mostly is not.
- It does not work if you want oceanfront. This is a downtown building, not a beach building, and the beach is a drive or a long walk.
- It does not work if you need four bedrooms or more than about 2,000 square feet. Look at Delray Ridge or the Boca towers instead.
Interiors and amenities

Onix was reported roughly one-third sold earlier in the sales cycle. That number moves. I can tell you which lines are actually left, what they are asking today, and whether the remaining inventory is the stuff you would want.

Onix is the entry point into new construction in downtown Delray. Delray Ridge is a different product entirely at a different price. Glass House is the Boca equivalent at a significant premium per foot.
Before you visit the sales gallery
- Bring your broker to the first visit. The gallery works for the developer. Developers here routinely welcome broker participation and pay the buyer's broker, so representation generally costs you nothing - but most require your broker to register with you on your first visit. Walk in alone and you may give that up permanently.
- Get the deposit schedule in writing. Florida pre-construction deposits are staged across construction milestones and held in escrow, with a statutory rescission window after you receive the condominium documents. That schedule, not the finish package, is the real commitment.
- Read the rental restrictions before contract if income is part of your plan.
- Treat the delivery date as an estimate. See the discrepancy noted above.
