Acre
An acre is a unit of land area equal to 43,560 square feet (about 0.405 hectares). In commercial real estate the acre is the standard unit for pricing and comparing land, but the number that actually drives value is not gross acreage — it is usable, buildable acreage after wetlands, setbacks, easements, and floor-area limits are applied.
Land in Florida is bought and sold by the acre, but two ten-acre parcels can carry wildly different values depending on how much of each is actually developable. Wetlands, conservation easements, retention requirements, setbacks, and zoning floor-area limits routinely strip usable area from raw acreage. This guide covers the acre as a measurement, how to convert acreage into buildable square footage, and the Florida-specific factors that separate gross acres from the acres a developer can actually build on.
The Acre as a Measurement
- 1 acre = 43,560 square feet (208.71 ft × 208.71 ft if square)
- 1 acre ≈ 0.4047 hectares; 640 acres = 1 square mile (a "section")
- Price per acre: The headline metric for raw and agricultural land
- Price per buildable SF: The metric that actually governs development land value
Converting Acreage to Buildable Square Footage
- Step 1 — gross to net: Subtract wetlands, easements, right-of-way dedications, retention/detention ponds, and required buffers to get usable acreage
- Step 2 — apply FAR: Buildable area = net land SF × the zoning floor area ratio. A 2.0 acre net site (≈87,120 SF) at a 0.5 FAR yields ≈43,560 SF of building
- Step 3 — check other caps: Height limits, parking ratios, and impervious-surface caps can bind before FAR does
- Density for multifamily: Residential land is often priced per door (units/acre allowed) rather than per SF
Gross vs Usable vs Buildable Acreage
- Gross acreage: The full parcel as surveyed — the number on the deed
- Usable acreage: Gross minus undevelopable areas (wetlands, floodway, easements, buffers)
- Buildable acreage: Usable area actually developable after zoning, setbacks, and site-plan constraints
- Underwriting rule: Never pay a per-acre price on gross acreage without confirming the usable/buildable fraction with a survey and a site-plan or zoning analysis
Florida-Specific Acreage Factors
- Wetlands and conservation: Florida's extensive wetlands and conservation easements often remove large fractions of raw acreage from development
- Stormwater/retention: Florida water-management district rules require on-site retention, consuming usable acreage
- Flood zones: Coastal and low-lying acreage may carry elevation and flood-zone constraints that raise cost or limit use
- Impact fees: Development is priced per unit/SF built, so impact fees effectively tax buildable area, not gross acres
- Covered land plays: An income-producing building on excess acreage can support a hold until entitlement — the covered land play

Frequently Asked Questions
How many square feet are in an acre?
An acre is exactly 43,560 square feet. If square, that is roughly 208.71 feet by 208.71 feet. One acre is about 0.4047 hectares, and 640 acres make up one square mile (a section).
How do you convert acres to buildable square footage?
First convert gross acreage to usable (net) acreage by subtracting wetlands, easements, right-of-way, retention areas, and buffers. Then multiply net land square footage by the zoning floor area ratio (FAR). For example, 2.0 usable acres (about 87,120 SF) at a 0.5 FAR yields roughly 43,560 SF of building — before checking height, parking, and impervious-surface caps that may bind first.
What is the difference between gross and usable acreage?
Gross acreage is the full surveyed parcel — the number on the deed. Usable acreage is gross minus undevelopable areas like wetlands, floodway, easements, and required buffers. Buildable acreage is the usable area actually developable after zoning, setbacks, and site-plan constraints. Two parcels with identical gross acreage can have very different buildable areas and therefore very different values.
Why does usable acreage matter more than gross acreage in Florida?
Florida has extensive wetlands, conservation easements, and water-management-district stormwater/retention requirements that frequently remove large fractions of raw acreage from development. Flood-zone and elevation constraints add cost on coastal parcels. As a result, paying a per-acre price on gross acreage without confirming the usable/buildable fraction — via survey and zoning analysis — is one of the most common Florida land-buying mistakes.
Who can help me analyze Florida development acreage?
Michael R. Linton at Linton Global Solutions analyzes gross-to-buildable acreage on Florida land and development deals — factoring wetlands, retention, flood zones, FAR, and impact fees so buyers price per buildable square foot or per door, not per raw acre. With 39 years of Florida CRE experience including land and covered-land-play transactions, Linton Global Solutions underwrites what you can actually build. Call (312) 612-1031.
Article Summary
An acre is 43,560 square feet, the standard U.S. land unit. In CRE the acre prices land, but value is driven by usable, buildable acreage — gross minus wetlands, easements, retention, and buffers, then filtered through zoning FAR, height, parking, and impervious caps. In Florida, wetlands, water-management retention rules, flood zones, and impact fees frequently strip large fractions from raw acreage, so buyers should price per buildable SF or per door. Mike Linton analyzes gross-to-buildable acreage on Florida land deals.
Key Takeaways
- ✓1 acre = 43,560 square feet ≈ 0.405 hectares.
- ✓Value tracks buildable acreage, not gross acreage.
- ✓Buildable SF = usable land SF × zoning FAR (then check caps).
- ✓FL wetlands, retention, and flood zones cut usable area.
- ✓Impact fees effectively tax buildable area, not raw acres.
- ✓Never pay per gross acre without a usable/buildable analysis.
