How Old Are Miami-Dade’s Homes? Year Built, City by City
When the homes in each Miami-Dade city were built, from the Census Bureau’s American Community Survey, with margins of error shown and the data free to download.

Research › Miami-Dade housing age
The median home in Pinecrest, South Miami, Miami Beach and Coral Gables was built in 1969, according to Census Bureau estimates, against 1980 across Miami-Dade County and 1988 across Florida.
“Homes” here means every housing unit: houses, townhouses, apartments and condos. The year is when the building was built, not when its wiring or panel was last updated, which the Census Bureau does not record. Each figure is an estimate with a margin of error, shown in the table.

Four older cities: Pinecrest, South Miami, Miami Beach, Coral Gables
In each of these four cities the median home was built in 1969, 11 years before the median for Miami-Dade County as a whole (1980). Between 51.5% and 52.7% of their homes were built before 1970. The margins of error on these medians are small enough (at most ±5 years, in South Miami) that all four are clearly older than the county median.
Miami-Dade’s housing is older than Florida’s: 49.6% of the county’s homes were built before 1980, against 34.0% statewide, and the county’s median year built is 8 years earlier than the state’s. It is about as old as the nation’s housing, where 49.7% of homes were built before 1980 and the median year is 1980.
The range inside the county is wide. In Miami Shores the median home dates from 1954; in Doral it dates from 2006, and 64.5% of Doral’s homes were built in 2000 or later.

Sorted from the oldest median year. ± is the margin of error at 90% confidence (years for the median, percentage points for the shares). †Wider margin of error. Communities are census-designated places, unincorporated areas the Census Bureau draws boundaries for. Source: Census Bureau, American Community Survey, 2020 to 2024 5-year estimates, tables B25034 (homes by year built) and B25035 (median year built). Shares are KRW Electric calculations from B25034.
Three places with a KRW Electric page are not in the table or the chart: Bay Harbor Islands, Surfside and Fisher Island. Their samples are small, and the margins of error on their shares are wider than 10 points, too wide to compare. Their figures are in the CSV, marked as not reliable. Coconut Grove is a neighborhood of the City of Miami, and the Census Bureau does not publish these tables for it separately; the City of Miami figures include it.
Homes from the 1960s and 1970s
28.8% of Miami-Dade’s homes (±0.5 points) were built from 1960 to 1979, against 23.9% across Florida. In Kendall the share is 49.5% and in Westchester 46.8%. Those decades matter for wiring: some homes built or rewired from the mid-1960s to the mid-1970s used aluminum branch wiring, which needs devices rated for it. Our post on aluminum wiring in older Miami homes explains how to tell. The Census Bureau does not record wiring type, so these figures cannot say how many homes have it.
What this means for an older home
- The age of the house is not the age of the wiring. Many older homes have had their panel replaced or circuits rewired, and the Census figure is the year the building went up. What matters is what is in the walls and the panel now.
- Insurers look at the electrical system on older homes. A four-point inspection asks when the electrical system was last updated; see our guide to the four-point inspection and your panel.
- Two-prong outlets usually mean no ground wire. The code allows several fixes; see two-prong outlets in older Miami homes.
- Adding big loads to an older home starts with the panel. An EV charger, a new air conditioner or a kitchen remodel can need more capacity than an original panel has; see EV charging in older Florida homes and panel upgrades.
- Not sure what you have? An electrical safety inspection looks at the panel, the wiring and the condition of the system, which also helps when you buy or insure a home.
Method, sources and limits
How we built it
All figures are from the Census Bureau’s American Community Survey, 2020 to 2024 5-year estimates: table B25034 (housing units by year the structure was built, in ten periods) and table B25035 (median year built). The shares built before 1970, before 1980, from 1960 to 1979 and in 2000 or later are our sums of the B25034 periods. Their margins of error use the Census Bureau’s formulas for derived estimates (ACS General Handbook). Medians and their margins are the bureau’s own.
How we checked it
Every median, margin and count on this page matches the bureau’s separate bulk download of the same tables (ACS summary file). Every share matches the bureau’s own percentages in its housing data profile (DP04) to within rounding.
Limits
- Homes means housing units. A single-family house counts once, and so does each apartment or condo unit, occupied or vacant. A condo in a tower built in 1970 counts as built in 1970.
- Year built is reported in a survey. People may not know exactly when an older building went up, so the early periods are less precise than the recent ones.
- These are estimates from a sample collected over five years. Each figure has a margin of error, shown as ±. Small places have wider margins; we left out three where they were too wide to compare.
- Places, not neighborhoods. Cities and villages are their legal boundaries; Kendall and Westchester are the Census Bureau’s statistical boundaries for those communities. Neighborhoods inside a city, such as Coconut Grove, are not shown.
- Nothing here describes the wiring or panel in any one home.
