Coastal Construction Starts $150M, 544-Unit Edgewater Tower

Miami-Dade issued a $150 million building permit on October 19 for a 39-floor, 544-unit residential tower at 1700 NE 4 Ave in Edgewater, county permit records show. Coastal Construction of Miami-Dade County is the general contractor, and the permit is held by an entity recorded as 1775 Biscayne L Cal LLC.

Why it matters

A $150 million permit at this stage is a construction start, not a filing or a rendering. Coastal Construction is one of South Florida’s busiest and most closely watched builders, with a track record of delivering supertall and large-scale residential towers across the county. Its name on a new 544-unit high-rise signals real near-term activity in Edgewater, a corridor that has drawn a wave of new residential towers north of downtown Miami as developers push beyond the saturated Brickell and Edgewater waterfront blocks closer to Biscayne Bay. For South Florida builders and trades, a permit this size means subcontractor bids, labor demand and material orders are already moving.

The numbers

The permit lists an estimated value of $150 million for 544 units across 39 floors, with about 840,000 square feet of building area, a construction cost of roughly $179 per square foot. The county charged $152,453 in permit fees on the filing. The property carries folio 0132310720010 at 1700 NE 4 Ave, legally described within the V Downtown plat. The proposed use is coded for residential buildings of five units or more, and the application itself was logged as new construction rather than a renovation or addition.

What’s next

No architect is listed on the permit record, and the county has not yet logged an inspection or certificate of occupancy date, both of which are normal at this early stage of a large multifamily build. Watch the Property Appraiser folio for the next assessed-value update once vertical construction is underway, and watch for Coastal Construction’s own project announcements, which typically follow a permit issuance by weeks rather than days.
