If you're planning a new concrete driveway in South Florida, the first question is always: how much will it cost? The short answer is $8 to $18 per square foot for a standard 4-inch broom-finish driveway in Broward, Miami-Dade, or Palm Beach County — but the real number depends on several factors specific to your property.
A typical two-car driveway (400-600 sq ft) runs between $3,200 and $10,800 installed. The wide range reflects differences in base preparation requirements, concrete thickness (4" vs 6"), finish type, reinforcement method, and site access conditions.
What Affects the Price?
Base preparation is the single biggest variable. Properties with stable limerock sub-bases need minimal prep, while sandy soils common in western Broward and Palm Beach require deeper excavation and compacted fill — adding $1-3 per square foot.
Concrete thickness matters for longevity. Standard residential is 4 inches, but properties with heavy vehicles or RV parking should use 6-inch slabs with wire mesh or rebar reinforcement.
Finish options range from basic broom finish ($8-12/sq ft) to exposed aggregate ($12-16/sq ft) to stamped decorative patterns ($14-22/sq ft).
Cost by County
Broward County averages $9-15 per square foot due to moderate soil conditions and competitive contractor availability. Miami-Dade runs slightly higher at $10-17 per square foot, driven by stricter permitting requirements and higher labor costs. Palm Beach County ranges from $10-18 per square foot, reflecting the premium finish expectations common in communities like Boca Raton and Wellington.
How to Get an Accurate Estimate
The only way to get a real number is a site assessment. Online calculators can't account for your soil conditions, drainage requirements, existing surface removal, or access limitations. A reputable contractor will visit your property, evaluate conditions, and provide a written proposal with line-item pricing — no hidden fees.
