Commercial construction in Florida costs roughly $175 to $455 per square foot for office space, $190 to $360 for retail, $80 to $160 for warehouses and $195 to $300 for multifamily, based on the latest published South Florida benchmarks. Those are hard construction costs only, and your project can land well outside them. This guide shows where the numbers come from, what they include, and how to turn a per-square-foot range into a budget you can actually use.

How we built these ranges

  • Source: the indicative construction cost table in RLB’s Q3 2026 North America report. RLB is an international cost consultancy that publishes these ranges quarterly for major markets. Miami is the Florida market in its table.
  • What the numbers are: hard construction costs in U.S. dollars per square foot of gross floor area. RLB notes that actual costs vary with site conditions, climate, specification standards and market conditions.
  • What’s excluded: land, design and engineering fees, permits and impact fees, financing, furniture and equipment, and owner contingency. Those soft costs come on top.
  • Why one market: we only publish figures we can source. RLB’s table covers Miami, so the ranges below are South Florida benchmarks. See the regional notes further down for how other Florida markets compare.

Florida commercial construction cost per square foot by building type

Cost escalation

RLB’s comparative cost index for Miami rose 4.55% from July 2025 to July 2026, slightly above the national figure of 4.45%. If your project won’t start for a year or more, carry escalation in the budget rather than pricing at today’s numbers.

How other Florida markets compare

RLB’s published table doesn’t break out Tampa, Orlando, Jacksonville or other Florida metros, so we don’t publish separate dollar figures for them. In practice, costs shift from the Miami benchmark because of:

  • Wind design: Miami-Dade and Broward are the only counties in the High-Velocity Hurricane Zone (HVHZ), with stricter product approvals and envelope requirements. Other regions use standard Florida Building Code wind provisions, which still require significant wind design along the coasts.
  • Labor and subcontractor markets: availability and pricing of trades vary across Florida’s metros and rural areas.
  • Site conditions: flood zones and high water tables on the coasts, karst and sinkhole-related foundation work in Central Florida, and stormwater requirements statewide.
  • Local codes and fees: county amendments, impact fees and permitting timelines differ by jurisdiction.

For a number specific to your site, the only reliable method is a takeoff from your drawings, priced to your local market. See our city pages for Miami, Fort Lauderdale, West Palm Beach, Tampa and Orlando.

Florida-specific cost premiums to watch

  • Impact-rated openings: windows, storefront and doors rated for wind-borne debris are often one of the largest envelope costs.
  • Roof systems and attachment: uplift requirements drive deck attachment, edge metal and roofing assemblies, with additional requirements in the HVHZ.
  • Rooftop equipment anchorage: curbs, tie-downs and engineered anchorage for mechanical units.
  • Coastal corrosion protection: the 2026 Florida Building Code adds corrosion-resistance requirements for fasteners and connectors within 3,000 feet of saltwater. See our 2026 code cost impact guide.
  • Flood design: elevation, floodproofing, flood-resistant materials and FEMA certifications in flood hazard areas.
  • Foundations: deeper foundations, ground improvement or dewatering where geotechnical reports call for them.

From cost per square foot to a real budget

A per-square-foot range is a starting point, not a budget. AACE International’s estimate classification (Recommended Practice 18R-97) shows how accuracy improves as design develops:

Estimate class Typical design maturity Typical use Typical accuracy range
Class 5 0% to 2% Concept screening Low: -20% to -50%; High: +30% to +100%
Class 4 1% to 15% Feasibility study Low: -15% to -30%; High: +20% to +50%
Class 3 10% to 40% Budget authorization Low: -10% to -20%; High: +10% to +30%
Class 2 30% to 75% Control or bid/tender Low: -5% to -15%; High: +5% to +20%
Class 1 65% to 100% Check estimate or bid Low: -3% to -10%; High: +3% to +15%

A benchmark range like the table above is roughly Class 5. A line-item estimate from schematic or design development drawings moves you to Class 3 or better, which is what lenders, investors and boards usually need.

Estimating by building type

Each building type has its own cost drivers. See what’s included and what to watch:

Frequently asked questions

What is the average cost per square foot for commercial construction in Florida?

Based on RLB’s Q3 2026 Miami benchmarks, hard costs range from about $80 to $160 per square foot for warehouses, $175 to $455 for office, $190 to $360 for retail, $195 to $300 for multifamily and $520 to $735 for hospitals. Soft costs, land and contingency are extra.

Do these ranges apply to Tampa, Orlando and Jacksonville?

They’re South Florida benchmarks. Other Florida markets differ because of wind design requirements, labor markets, site conditions and local fees. Use them as a reference point, then get a project-specific estimate.

Do the ranges include soft costs?

No. They’re hard construction costs per square foot of gross floor area. Design fees, permits, impact fees, financing, furniture and equipment, land and owner contingency are additional.

How fast are construction costs rising in Florida?

RLB’s cost index for Miami rose 4.55% between July 2025 and July 2026, compared with 4.45% nationally.

How accurate is a cost-per-square-foot estimate?

Very rough. Under AACE’s classification, a concept-level estimate can be 20% to 50% low or 30% to 100% high. A line-item estimate from drawings narrows that range considerably.
