What building in Miami-Dade County actually involves
Cost per square foot is one number. These are the local conditions behind it.
How busy this market is
Miami-Dade County ranks 16th of 67 counties in Florida for single-family permits issued in 2025, accounting for 2.4% of all the single-family homes permitted statewide that year.
That is an active market with a reasonable choice of builders.

What land adds on top
Land averages 30% of finished property value in Florida, which is a markup of about 43% on construction cost. For the $442,000 build above, that implies roughly $190,060 for the lot.
This is a statewide figure. Lots inside Miami-Dade County's built-up areas will run above it and rural parcels below, so treat it as an order of magnitude rather than a budget line.

Climate, spec and timing
- 523 heating and 3,923 cooling degree days a year in Florida — cooling drives the mechanical budget. (NOAA, 2016-2025 average)
- The median new home in the South is 2,162 sq ft and the Census median contract price there is $157.3/sq ft, excluding land — the same basis as our estimate above. (Census Survey of Construction 2025)
- Florida issued 111,173 single-family permits in 2025 overall. See the 35-year state history.
Reconciling our estimate with permit filings
The average declared valuation on Miami-Dade County permits was $475,296 per single-family unit, against our $442,000 estimate for a 2,000 sq ft mid-range build. These two numbers are not measuring the same thing and should not match: builders declare a valuation for permit-fee purposes, which is routinely below the finished construction cost, and the permits cover homes of every size and finish level rather than a 2,000 sq ft mid-range one. We show both because the gap between them is itself informative — and because quoting only the flattering one would be dishonest.
