What Drives Multi-Family Building Construction Costs in Coral Gables?
Coral Gables’s construction landscape is influenced by several high-cost factors. Land in prime locations like Mizner Park or near Florida Atlantic University ranges from $100 – $250 per square foot due to high demand and limited availability, while more suburban areas like West Boca offer slightly lower prices at $50 – $150 per sq ft. The city’s coastal location requires hurricane-resistant construction, including reinforced concrete, impact-resistant glass, and elevated foundations, which significantly increase material and labor expenses.
